SERIAL PUBLICATIONS OF THE SMITHSONIAN INSTITUTION

The emphasis upon publications as a means of diffusing knowledge was expressed by the first Secretary of the Smithsonian Institution. In his formal plan for the Institution, Joseph Henry articulated a program that included the following statement: “It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge.” This keynote of basic research has been adhered to over the years in the issuance of thousands of titles in serial publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series:

Smithsonian Annals of Flight

Smithsonian Contributions to Anthropology

Smithsonian Contributions to Astrophysics

Smithsonian Contributions to Botany

Smithsonian Contributions to the Earth Sciences

Smithsonian Contributions to Paleobiology

Smithsonian Contributions to Zoology

Smithsonian Studies in History and Technology

In these series, the Institution publishes original articles and monographs dealing with the research and collections of its several museums and offices and of professional colleagues at other institutions of learning. These papers report newly acquired facts, synoptic interpretations of data, or original theory in specialized fields. These publications are distributed by subscription to libraries, laboratories, and other interested institutions and specialists throughout the world. Individual copies may be obtained from the Smithsonian Institution Press as long as stocks are available.

Kornicker, Louis S. Myodocopid Ostracoda from Southern Africa. Smithsonian Contributions to Zoology, number 214, 39 pages, 24 figures, 1976.—Ostracoda from Lüderitz Bay, South-West Africa, identified by Klie (1940) as Asterope grimaldi Skogsberg, 1920, and Asterope muelleri Skogsberg, 1920, were restudied and referred to three new species: Cylindroleberis kliei, Parasterope beta, and Parasterope kappa. The new species are described and illustrated. Paradoloria dorsoserrata (Müller, 1908), the type-species of the genus Paradoloria, is redescribed from syntypes from off the coast of South Africa. The identification by Klie (1940) of Paradoloria dorsoserrata in Lüderitz Bay is tentatively confirmed. It is concluded that ostracodes from the vicinity of Japan identified by Poulsen (1962) as Paradoloria dorsoserrata were correctly referred by Hanai (1974) to Paradoloria pellucida (Kajiyama, 1912).

OFFICIAL PUBLICATION DATE is handstamped in a limited number of initial copies and is recorded in the Institution’s annual report, Smithsonian Year. SI PRESS NUMBER 6068. SERIES COVER DESIGN: The coral Montastrea cavernosa (Linnaeus).

Introduction

Skogsberg (1920:510) reported Asterope grimaldi Skogsberg, 1920 (= Cylindroleberis grimaldi), from the Mediterranean Sea near Monaco. Later, Klie (1940:409) reported it from Redfort Bay and Lüderitz Bay, South-West Africa. Its absence from the coast of Mauritania (Kornicker and Caraion, 1974) suggested a disjunct distribution of the species—the Mediterranean Sea and South-West Africa. For this reason, it seemed advisable to reexamine Klie’s specimens. These were obtained from the Hamburg Zoological Museum and are described herein as Cylindroleberis kliei, new species.

Skogsberg (1920:483) reported Asterope muelleri Skogsberg, 1920 (= Parasterope muelleri), from the English Channel and the Mediterranean Sea. It has since been reported from many localities including the Bahamas (Kornicker, 1958:239), the West Indies (Poulsen, 1965:370), and off Mauritania (Kornicker and Caraion, 1974:8). Klie (1940:409) reported the species from Lüderitz Bay, South-West Africa. Klie’s identification was questioned by Poulsen (1965:370), Kornicker (1974:36), and Kornicker and Caraion (1974:8). Because of this, the specimens identified by Klie were obtained from the Hamburg Zoological Museum and restudied. Most were found to be very closely related to Parasterope muelleri Skogsberg, but sufficient differences were detected to refer them to Parasterope beta, new species. Three specimens in the same vial as the specimens identified as A. muelleri by Klie (= Parasterope beta) are described herein as Parasterope kappa, new species.

Müller (1908) described Paradoloria dorsoserrata (as Cypridina dorsoserrata) from Simonstown, South Africa, and Klie (1940) reported the species from Lüderitz Bay, South-West Africa. Poulsen (1962) reported it from off Misaki, Japan, but Hanai (1974:119) referred Poulsen’s specimens to Paradoloria pellucida (Kajiyama, 1912). Examination of syntypes of P. dorsoserrata described below leads me to concur with Hanai. I also examined a juvenile (described below) from Lüderitz Bay in the collection reported on by Klie (1940), and tentatively agree that P. dorsoserrata was present in the bay. Hanai (1974:119) designated P. dorsoserrata the type-species of Paradoloria.

ACKNOWLEDGMENTS.—I thank Dr. Gerd Hartmann, Hamburg Zoological Institute and Museum, for sending specimens reported on by Klie (1940), and Dr. H.-E. Gruner, Berlin Zoological Museum, for sending syntypes of Paradoloria dorsoserrata (Muller, 1908). Criticisms of the manuscript by Dr. Thomas E. Bowman and Ms. Maura McManus are appreciated. Preliminary camera lucida drawings of appendages were made by Mr. Paul Mazer, who also inked the final drawings. The assistance of Mr. Walter R. Brown and Ms. Mary J. Mann, who operated the scanning electron microscope, is acknowledged with thanks.

CYLINDROLEBERIDIDAE Müller, 1906

CYLINDROLEBERIDINAE Müller, 1906

Cylindroleberis Brady, 1868

A vial containing 46 specimens identified by W. Klie as Asterope grimaldi Skogsberg was received from the Hamburg Zoological Museum. These had been collected in Lüderitz Bay in February, 1938, by Dr. v. Levetzow. Klie (1940) had reported 50 specimens from Lüderitz Bay and 1 specimen from Redfort Bay. This indicates that the specimens I studied represent the bulk of the collection. All the specimens in the vial are referred to Cylindroleberis kliei, new species.

The new species brings to two the number of species of Cylindroleberis reported from the west coast of Africa.

The new species, C. kliei, differs from both species in having more bristles on the posterior infold between the list and edge of valve, and in having processes on the posterior infold. The carapace of C. kliei also differs from that of C. verrucosa in not having teeth along the lower margin of the incisur.

Parasterope Poulsen, 1965

Two vials containing 78 specimens identified as Asterope muelleri Skogsberg by W. Klie were received from the Hamburg Zoological Museum. These had been collected in Lüderitz Bay in February, 1938, by Dr. v. Levetzow. Klie (1940) had reported 97 specimens of A. muelleri from that locality. This indicates that the specimens I studied represent the bulk of the collection. I divided the specimens into three groups: one group consists of 48 specimens of Parasterope beta, new species; a second group consists of 3 specimens of Parasterope kappa, new species; and a third group consists of 27 specimens, mostly juveniles, of Parasterope species indeterminate. All specimens were returned to the Hamburg Zoological Museum.

The two new species bring the number of species of Parasterope reported from the western coast of Africa to 7. Of the 7, only 4 have adult females with tumid (pear-shaped) carapaces in lateral view. Because the new species are easily distinguishable from the nontumid species on shape of carapace, the key above is just for tumid species.

Sexual dimorphism: In addition to usual differences, the dorsal margin of the mandibular basale of the male bears 1 midbristle absent on the female. The posterior of the female bears 4–5 sclerotized lateral crescents absent on the male. The furca of the female bears 9 claws, whereas, that of the male bears only 8. The presence of a midbristle on the dorsal margin of the mandibular basale of males and its absence on females has been previously noted on Parasterope quadrata (Brady, 1898) and Homasterope maccaini Kornicker, 1975 (Kornicker, 1975).

Comparisons: The specimens upon which the new species, Parasterope beta, is based had been identified by Klie (1940) as Asterope muelleri Skogsberg, 1920 (= Parasterope muelleri), a species very close to the new species. The main difference between them is that the dorsal margin of the mandibular basale of the adult male of P. beta bares a midbristle which is absent on P. muelleri. The maximum reported carapace length of adult females of P. muelleri is 1.41 mm, whereas, the range of the length of carapaces of adult females of P. beta is 1.47–1.60 mm. The new species is also closely related to Parasterope alpha Kornicker and Caraion, 1975, which was described from a single adult female from the continental shelf off the Islamic Republic of Mauritania. The species are separated mainly by the number of ommatidia in the lateral eyes: 13-14 for P. alpha and 18-19 for P. beta. Also, the distal bristle on the dorsal margin of the basale of the maxilla of P. beta is longer than that bristle of P. alpha. When the male of P. alpha becomes known, the relationship between P. alpha and P. beta should be reassessed.

Sexual dimorphism: The 2nd joint on the exopodite of the 2nd antenna of the adult male of P. kappa is only slightly longer than the 3rd joint. On adult males of most species of Parasterope the 2nd joint is considerably longer than the 3rd. Unfortunately, the c- and g-bristles of the 1st antennae of the only male P. kappa in the collection are broken, but their slender bases suggest that they may not be extremely long like on adult males of most other species of Parasterope.

Comparisons: The combination of a short bare bristle on the ventral margin of the mandibular basale proximal to the U-shaped depression, the small size of the carapace, and the number of ommatidia in the lateral eyes of the male and female (13–14) distinguishes P. kappa from other species in the genus.

Paradoloria Poulsen, 1962

Three species in the vicinity of South Africa and South-West Africa have been referred to the genus Paradoloria (Poulsen, 1962:147–149): P. dorsoserrata (Müller, 1908), P. vanhoeffeni (Müller, 1908), and P. capensis (Cleve, 1905). The description of P. capensis is inadequate to refer it to Paradoloria with certainty (Poulsen, 1962:147; Kornicker, 1975:141).

TYPE-LOCALITY.—Simonstown, Union of South Africa, 35°15′S, 19°45′E, bottom sample.

DISTRIBUTION.—In addition to the type-locality, the species has been reported from Langebaan, Velddrift, and Kometje, Union of South Africa, by Hartmann and Schröder (1975:360, table 4), and from Lüderitz Bay, South-West Africa, by Klie (1940:406) and Hartmann and Schroder (1975:360, table 4).

MATERIAL.—Through the courtesy of Dr. H. -E. Gruner, I received from the Berlin Zoological Museum a vial containing 2 labels, “Gaussexp. 166-Simonst.,” and “Types, Kat. Nr. 19097, Species Cypridina dorsoserrata G. W. Muller, 1908, Fundort Simonstown, South Africa, Biotop 35°15′S, 19°45′E, bottom sample, gesammelt von l.VII. 1903, Dat. Deutsche Südpolar Exp., determiniert von G. W. Müller.” The vial contained 109 specimens and 1 larval clam. I dissected 2 adult females designated herein “Müller female specimen number 1 and number 2,” and 1 adult male designated herein “Müller male specimen number 1,” and partly dissected 1 adult male designated herein “Muller male specimen number 2” and 1 female designated “Müller female specimen number 5.” Also partly dissected were I A–1 male and I A–2 ?male. All specimens were returned to the Berlin Zoological Museum.

I received from the Hamburg Zoological Museum through Dr. Gerd Hartmann a vial containing 3 labels: “art”; “07”; “Asterope mülleri Skogsberg, D. S. W. Africa: Lüderitz Bucht, February 1938. Coll. v. Levetzow.” The vial contained in addition to 72 cylindroleberids, 1 juvenile cypridinid, which I have identified as Paradoloria dorsoserrata. The specimen was returned to the Hamburg Zoological Museum.

Genitalia: Not developed.

Lateral eye: Well developed.

Posterior: Margin smooth (Figure 23b).

Note: Specimen examined assumed to be a male because of the presence on the 7th limb of a peg opposite the comb.

DESCRIPTION OF A JUVENILE ?MALE, KLIE SPECIMEN FROM LÜDERITZ BAY, (see “Material,” page 23) (Figure 24).—Carapace similar to that of A-l male described above (Figure 24a); length 1.50 mm, height 1.01 mm.

FIGURE 23.—Paradoloria dorsoserrata (Müller), Müller specimen number 4, A-2 ?male, syntype, length 1.32 mm: a, complete specimen showing outline of lateral eye; b, posterior of body, anterior to left. Müller specimen number 3, A 1 male, syntype, length 1.71 mm: c, outline of complete specimen; d, posterior of body, anterior to right; e, right copulatory organ, anterior to right. Müller male specimen number 2, adult male, syntype, length 2.05 mm: f, posterior of animal (stippled) shown inside the shell. (Same magnification in micrometers: b,d.)

(Same magnification in micrometers: b,d,e.)

Second antenna: Similar to that of adult male but with only 2 long bristles and 1 short bristle on 1st endopodite joint.

Seventh limb: Each limb with 11 tapered bristles and a single peg with small teeth on inner margin opposite comb.

Furca (Figure 24b): Similar to that of adult male but with only 9 claws and claw 3 shorter than claw 4.

Medial eye and rod-shaped organ (Figure 24d): Similar to that of adult male.

Lateral eye: Well developed (Figure 24c).

Posterior: Margin very weakly undulate.

Upper lip (Figure 24e): Similar to that of adult male.

Remarks: The presence of a peg opposite the comb of the 7th limb suggests that the specimen is a male, but no copulatory organ was observed. The 7th limb contained about the same number of bristles present on the A-2 ?male described above, but that specimen had a smaller carapace. I have tentatively identified the specimen as P. dorsoserrata; however, it will be necessary to examine adult males and females of specimens identified by Klie as P. dorsoserrata in order to verify his identification.

SEXUAL DIMORPHISM.—In addition to usual dimorphic characters such as differences in the 1st antennae, the following differences were observed.

Carapace: Caudal process of male carapace slightly more prominent than that of female.

Seventh limb: Terminal jaw bare on female, with spinous process on male.

Posterior: Smooth on female, serrate on male.

Lateral eye: Slightly larger on male.

REMARKS CONCERNING SPECIMENS FROM JAPAN REFERRED TO P. dorsoserrata BY POULSEN (1962).—Because of differences in the endopodite of the 2nd antenna, number of furcal claws, and the posterior margin of the body of the male, I concur with Hanai (1974) that the Japanese and South African forms are not conspecific. The Japanese forms were correctly referred by Hanai (1974:119) to Paradoloria pellucida (Kajiyama, 1912).

Copy must be typewritten, double-spaced, on one side of standard white bond paper, with 1½″ top and left margins, submitted in ribbon copy with a carbon or duplicate, and accompanied by the original artwork. Duplicate copies of all material, including illustrations, should be retained by the author. There may be several paragraphs to a page, but each page should begin with a new paragraph. Number consecutively all pages, including title page, abstract, text, literature cited, legends, and tables. The minimum length is 30 pages, including typescript and illustrations.

The title should be complete and clear for easy indexing by abstracting services. Taxonomic titles will carry a final line indicating the higher categories to which the taxon is referable: “(Hymenoptera: Sphecidae).” Include an abstract as an introductory part of the text. Identify the author on the first page of text with an unnumbered footnote that includes his professional mailing address. A table of contents is optional. An index, if required, may be supplied by the author when he returns page proof.

Two headings are used: (1) text heads (boldface in print) for major sections and chapters and (2) paragraph sideheads (caps and small caps in print) for subdivisions. Further headings may be worked out with the editor.

In taxonomic keys, number only the first item of each couplet; if there is only one couplet, omit the number. For easy reference, number also the taxa and their corresponding headings throughout the text; do not incorporate page references in the key.

In synonymy, use the short form (taxon, author, date:page) with a full reference at the end of the paper under “Literature Cited.” Begin each taxon at the left margin with subsequent lines indented about three spaces. Within an entry, use a period-dash (.—) to separate each reference. Enclose with square brackets any annotation in, or at the end of, the entry. For references within the text, use the author-date system: “(Jones, 1910)” and “Jones (1910).” If the reference is expanded, abbreviate the data: “Jones (1910:122, pl. 20: fig. 1).”

Simple tabulations in the text (e.g., columns of data) may carry headings or not, but they should not contain rules. Formal tables must be submitted as pages separate from the text, and each table, no matter how large, should be pasted up as a single sheet of copy.

Use the metric system instead of, or in addition to, the English system.

Illustrations (line drawings, maps, photographs, shaded drawings) can be intermixed throughout the printed text. They will be termed Figures and should be numbered consecutively; however, if a group of figures is treated as a single figure, the components should be indicated by lowercase italic letters on the illustration, in the legend, and in text references: “Figure 9b.” If illustrations (usually tone photographs) are printed separately from the text as full pages on a different stock of paper, they will be termed Plates, and individual components should be lettered (Plate 9b) but may be numbered (Plate 9: figure 2). Never combine the numbering system of text illustrations with that of plate illustrations. Submit all legends on pages separate from the text and not attached to the artwork. An instruction booklet for the preparation of illustrations is available from the Press on request.

In the bibliography (usually called “Literature Cited”), spell out book, journal, and article titles, using initial caps with all words except minor terms such as “and, of, the.” For capitalization of titles in foreign languages, follow the national practice of each language. Underscore (for italics) book and journal titles. Use the colon-parentheses system for volume, number, and page citations: “10(2):5–9.” Spell out such words as “figures,” “plates,” “pages.”

For free copies of his own paper, a Smithsonian author should indicate his requirements on “Form 36” (submitted to the Press with the manuscript). A non-Smithsonian author will receive 50 free copies; order forms for quantities above this amount with instructions for payment will be supplied when page proof is forwarded.
