NATIONAL MUSEUMVol. 87 Washington : 1939 No. 3075A TAXONOMIC STUDY OF NEOTROPICAL BEETLES OFTHE FAMILY MORDELLIDAE, WITH DESCRIPTIONSOF NEW SPECIES By Eugene Ray The Morclellidae are an obscure family of small or minute beetlesthat have never commanded much attention, owing to the relativelyinnocuous habits of the adults and larvae. Very little has ever beendone with this group except in a taxonomic way, and not a singlecomplete life history is known.Unfortunately, many of the forms collected in obscure places areknown only from unique specimens. It seems unlikely that taxono-mists will ever arrive at a point where unlimited material will beavailable for all species, and, no doubt, many uniques will remainalone in collections for years to come. However, some of thesesingle individuals are sufficiently distinct from their closest alliesin the matter of actual description and structural characters to per-mit their proposal as new names. It has been the policy of thepresent writer to describe such uniques only when they can be sepa-rated on the basis of characters that are known not to vary in othermembers of the family. Many more, which seem distinct but areclosely allied to known forms, have been set aside without names,because the characters needed for their separation are known to bevariable in certain cases. No description has been made on thebasis of color and pubescent markings alone, since these featuresare often considerably aberrant, but rather, when one or more struc-tural points of differentiation can be found, the color and pattern165175?39 1 271 272 PROCEEDINGS OF THE NATIONAL MUSEUM vou 87 of pubescence are distinct enough to make immediate, superficialseparation possible. In all cases a combination of characters, ratherthan a single one, has been used for specific and generic diagnosis.A peculiar characteristic has been observed in the present study.At the ends of the tarsi are the tarsal claws, which are distinctstructures bearing one or more teeth on their mesal surfaces. Theseteeth apparently vary in number, position, and shape according tothe species being considered. At present it seems premature to statedefinitely that these will form a new character of specific value,but there is apparently a diversity of detail that seems to providemuch the same diagnostic character as that provided by the geni-talia in certain other groups.Closely appressed to the tarsal claws, and scarcely distinguishablewithout being mounted on a slide, is an additional pair of tarsal "claws," somewhat less heavily chitinized than the other pair. These "claws" are attached to the pretarsus at the same point as the otherpair. Their specific value is probably somewhat less than that ofthe external pair, owing to their lesser chitinization, which permitsa bending into various shapes before the integument hardens uponemergence of the adult insect" This character has been observedonly in the subfamily Mordellinae, the Anaspinae apparently beingwithout it. In addition, all the Anaspinae that the writer has ob-served have but the single terminal tooth on the tarsal claw.One new genus and 29 new species are herein recorded. Thirtyothers are found to be much more widely distributed than has hith-erto been supposed. Mention of described species is limited to thoseforms known only from restricted localities. One other species istaken out of synonymy.This study has been based primarily on material received fromthe United States National Museum and the Mexican Departmentof Agriculture, together with a small series of specimens from theUniversity of Puerto Rico and the Deutsches Entomologisches In-stitut. The types of all new species are deposited in the NationalMuseum.^ Paratypes, when available, remain in the collection ofthe writer.Grateful acknowledgment is made to officials of the NationalMuseum ; Dr. A. Dampf , chief entomologist of the Mexican Depart-ment of Agriculture; Prof. S. A. Danforth, of the University ofPuerto Rico; and Dr. Walther Horn, director of the DeutschesEntomologisches Institut. My thanks are due to Miss Kathryn Sum-merman and Julius Bosen, graduate students in the Department ofEntomology at the University of Illinois, for their kind assistance ? The types of Mordella militaris, new species, received from the Deutsches Entomo-logisches Institut, are returned to that institution.

Busck) ; one from Trinidad Rio, Panama, March 8, 1912 (A.Busck) . This species, originally described from Florida, has, I believe,been wrongly suppressed as a synonym of G. hilaris (Say) (1835,p. 190) since the publication of the J. B. Smith paper in 1882.Additional specimens, from the Dominican Republic and Panama,as recorded above, tally more closely with the Florida types in theUnited States National Museum than with true specimens of hilaris{vide Barber, on pin label of specimen, det. 1935). Structurally,there can be no doubt that the two species are distinct. Comparisonof specimens of hilaris from Illinois with the above-mentioned exam-ples of hieroglyphica shows distinct differences in the maxillary palpi,antennae, and tarsal claws (fig. 17, k^ I). In addition, the pattern ofthe dermal color and pubescence of the dorsal surface is distinctlydifferent. In my opinion there can be no doubt that hieroglyphicamerits valid specific standing.Genus TOMOXIA CostaTomoxia Costa, Fauna Regni Napoli, Mordellidae, p. 8, 1854.TOMOXIA SPINIFER ChampionTomoxia spinifer Champion, Biologia Centrali-Americana, Coleoptera, vol. 4,pt. 2, pp. 261, 462, pi. 9, figs. 8, 8a, 1S91.Three specimens: One from Turrialba, Costa Rica (Schild andBurgdorf) ; one from Livingston, Guatemala, April 5 (Barber andSchwarz) ; one from Peru, October 3, 1935, found dead in dried woodat Washington, D.

TAXONOMIC STUDY OF MORDELLIDAE?RAY 277TOMOXIA SERRICORNIS, new speciesFiGUBE 16, gThis species is most closely allied to Komi Ray (1936b, p. 147)but may adequately be separated from the latter member of thegenus by the more parallel-sided form, difference in color and patternof pubescence, the greater length of the intermediate tarsi and ofthe outer tibial spur, and the shorter elytra.Length : 3.4 mm. ; including anal style, 4.1 mm.

Morrison).MORDELLOIDES, new genusThis genus is allied to both Zeamordella Broun (1886, p. 847) andMordella Linnaeus (1758, p. 420). From the former it may be sepa-rated by the angular insertion of the distal segment of the maxillarypalpi, the much longer length of the posterior legs, the thin, filiformtarsi, and the much longer, acute anal style. From Mordella it maybe separated by the semicircular scutellum, the lengthy intermediatetibiae, the angulate anterior angles of the pronotum, the single flat-tened spur of the posterior tibiae, and the truncate apex of the lastventral segment. From Reynoldsiella Ray (1930, p. 184), to which 278 PROCEEDINGS OF THE NATIONAL MUSEUM vol.87genus it is also allied, it may be separated by the presence of a sub-apical ridge on the posterior tibiae, the much narrower shape of thebody, the flat tibial spur, and characters as mentioned in comparisonwith MordelJa above. Mordelloides, Zeamordella^ and Reynoldsiellamay be linked together because of the semicircular scutellum.The single broad, flattened spur of the posterior tibiae is uniqueamong known Mordellidae and will readily separate this form fromany other member of the family.Form suboval, moderately robust, convex. Distal segment of maxil-lary palpi broadly, equilaterally triangular, inserted at the corner.Antennae subserrate, distal segment distinctly longer than penulti-mate segment. Pronotum much broader than long, anterior anglesobtuse, not rounded. Scutellum fairly large, semicircular. Mesoster-num produced posteriorly in the form of a rounded lobe. Posteriorcoxae elongate, contiguous, meeting in a depressed sutural line ; ante-rior margin of latter part closely connected with rounded lobe ofmesosternum. Anal style long, more than four times length of lastventral segment, broadest at its basal fifth, then suddenly narrowedand attenuate to apex, curved ventrad. Intermediate tibiae longerthan their tarsi, the latter filiforta ; posterior tibiae with but a single,broad, flattened, tibial spur, concave on its anterior surface, convexon its posterior surface.The genotype is Mordelloides acuticauda^ new species, describedbelow. MORDELLOIDES ACUTICAUDA. new speciesFigures 17, i; 19, hThe single, flattened spur of the posterior tibiae, the semicircularscutellum, the peculiar antennae, and other generic characters willserve adequately to separate this species from any of its allies thatmight superficially resemble it.Length : 2.3 mm. ; including anal style, 5.8 mm.

Bodydensely covered with fine, recumbent, flavous pubescence.Antennae 0.5 mm. long, reaching intermediate coxae; segment 2twice as long as 1; 3 slightly longer than 4; 4-6 equal 7-10 broad-ened, forming a loose, elongate club, each segment distinctly broaderthan long; 11 as long as 10, but narrower, broadest subbasally, sidesand apex rounded. Distal segment of maxillary palpi enlarged,elongate, with form of a scalene triangle, apical margin veryobliquely truncate, corners and sides rounded; terminal segment oflabial palpi slender, apical half prolonged, acuminate. Pronotumdistinctly broader than long (0.65 by 0.45 mm.), apex and sidesbroadly rounded in a continuous semicircle, broadest at base, basalangles acute, base arcuate, midbasal lobe short, but rounded; entiresurface covered with fine, transverse strigae. Scutellum moderatelylarge, semicircular. Elytra almost two-thirds longer than broad(1.25 by 0.8 mm.), lateral margin distinctly curved, broadest sub-medially, apical fourth broadly rounded, apices individually curved ; basal fourth of surface faintly covered with transverse strigae. Pe-nultimate and antepenultimate segments of anterior and intermediatelegs much shortened, as broad as long. Tarsal claws with but thesingle distal prolongation.Type locality.?Ponce, Puerto Rico.ry;?e.?Female, U.S.N.M. No. 52921. TAXONOMIC STUDY OF MORDELLIDAE?RAY 313 'Remarks.?The type and seven female paratypes were collected atPonce, Puerto Rico, August 7, 1933, on flowers of Randia mitis(R. G. Oakley). Another female paratype, from the same locality,was taken on August 8, 1935 (R. G. Oakley). Since six of the speci-mens have protruding genitalia and all are alike in other respects,I am obliged to consider them as apparently all females.The markings on the elytra vary considerably in both width offasciae and depth of color. In one specimen they are visible onlywhen turned at an angle to the disk.Genus ANTHOBATULA StrandAnthobatula Strand, Acta Univ.

A. multipilis is not closely allied to anyof the North American members of the genus.Length : 2.1 mm. Form oblong-ovate, rounded anteriorly and pos-teriorly, broadest near middle of elytra. Derm piceous, dull, apexof front, clypeus, metasternum, abdomen, legs, and antennae casta-neous, maxillary palpi and genitalia flavous. Body densely coveredwith fine, short, recumbent pubescence, silvery on dorsal surface, par-taking of ground color ventrally.Antennae 0.7 mm. long, reaching intermediate coxae; segments3-6 equal; 7-10 each twice as long as 5 but slightly broader; 11slightly longer and narrower than 10, sides straight, apex rounded.Distal segment of maxillary palpi enlarged, with form of an elon-gate, scalene triangle, basal and apical angles acute, mesal angleobtuse, all rounded, sides straight, except apical fifth of lateralmargin, which is distinctly rounded. Pronotum one-half broaderthan long (0.9 by 0.6 mm.), sides and apex broadly rounded in asingle continuous curve, basal angles obtuse, base arcuate, midbasallobe very short, but rounded. Scutellum subtriangular, sides andapical angle rounded. Elytra but one-half longer than broad (1.5by 1 mm.), sides visibly rounded, broadest postmedially, apicesindividually rounded; surface completely covered with numerous,fine, transverse strigae. Intermediate and posterior tibiae approxi- 314 PROCEEDIlSrGS OF THE NATIONAL MUSEUM vol. 87mately equal in length to their tarsi, third and fourth segments oflatter structure short, fourth segment dilated, receiving distal seg-ment in a cavity near basal margin. Tarsal claws with but a singletooth, the distal prolongation.Type locality.?Cayamas, Cuba.Type.?M^\Q., U.S.N.M. No. 52932.Reriiarlcs.?The type was taken on January 17, the allotype onJanuary 16, seven paratypes (2 males, 5 females) were taken Jan-uary 22, February 3, January 20, February 10 (2), February 24,and June 10; all were taken at Cayamas, Cuba (E. A. Schwarz).There is some variation in the color of the ventral surface and inthe extent of the castaneous area on the front and clypeus. It isentirely possible that some specimens in a larger series would beentirely piceous. LITERATURE CITEDBroun, T.18S6. Manual of New Zealand Coleoptera, pt. 4.Champion, G. C. *1891. Mordellidae.
