Hylaeogena bellamyi Hespenheide , new species ( Fig. 8 )

Description. Holotype female. Roundedpentangular to ovate, broadly truncate in front, attenuate behind, moderately shiny; inconspicuously, minutely, and sparsely setose above and beneath, scutellum glabrous, black; ventral 1/2 of front with faint reddish or golden reflections, dorsal 1/2 of front, pronotum, and elytra with bluish reflections, stronger on elytra; 2.95 mm long, 1.95 mm wide ( Fig. 8 ). Head: Nearly transverse, 1.15 mm wide, very weakly convex, with very weak medial depression; surface sparsely, finely punctate and shagreened; epistomal area broad, deeply emarginate but not carinate along base, antennae inserted on outer margins of antennal cavities just interior to inner margins of eyes, pore in antennal cavity slightly above and interior to antennal insertion, additional pores at inner margin of eye, and directly above antennal insertion. Pronotum: Shallowly convex in cross-section, 3-1/3X as wide as long at middle, 1/3 narrower at apex than at base, and widest at base; sides weakly rounded to nearly quadrate apical angles; anterior emarginate with broad, shallow medial lobe; base subequal to humeral angles of elytra, angling backward to elytral lobe where it is narrowly emarginate, then nearly transverse anterior to scutellum, posterior angles slightly obtuse; weakly arcuate prehumeral carinae 1/2 length of pronotum; surface very weakly depressed along sides, disk finely punctate and shagreened. Scutellum: Shagreened, triangular, 2X as wide as long. Elytra: As wide as pronotum at base and widest at basal 1/3; humeral angles subquadrate; sides expanded behind base to basal 3/8, then narrowed to tips which are conjointly rounded; lateral margins nearly linear, and nearly straight from base to apex when viewed from side; each elytron with small, oval depression at base, and deeper, broader depression behind humerus along lateral margin to middle; surface polished along suture behind scutellum, otherwise finely, weakly rugulose, punctate in rows. Venter: Prosternum deeply rectangularemarginate in front; prosternal process broad, sides parallel between coxal cavities and rounded-truncate at apex. Hypomeron with strong, narrow antennal groove internal to pronotal margin for 1/2 length of margin. Abdomen beneath sparsely ocellate punctate; intervals faintly shagreened; last ventrite narrowly rounded at apex with deflexed teeth – 3 broad truncate medial teeth flanked on each side by 1 narrower truncate tooth and 1 much shorter acute tooth.

Type Material. Holotype: PANAMA: Chiriquí, Caldera (3 km NE) at Rio Chiriquí, 450 m, 01.06.1983, P. J. Spangler, R.A. Faitoute, W.E. Steiner ( USNM).

Etymology. The species is named in honor of C. L. Bellamy.

Discussion. This species is closer to H. capitata than to H. speculum but differs from the former species in being only inconspicuously rather than conspicuously setose on much of the dorsal surface and having only seven larger, mostly truncate teeth on the last abdominal ventrite, rather than about a dozen smaller acute teeth.
