description: Hypogena brasiliensis (Kulzer, 1962)
(Figs 1, 15, 16)
Ulosonia brasiliensis Kulzer, 1962: 94.
Type Material: HOLOTYPE (male) labeled: (a) on green paper “ Brazil / S Leopoldo”; (b) on red bordered paper “ HOLOTYPUS / Ulosonia brasiliensis / det. H. Kulzer 1962 ”; (c) Tenebrionid Base / Aaron D. Smith / Catalog # 20134” (NHMB). PARATYPE (male) labeled: “ Brasilien, S. Leopoldo ”. (NHMB). This paratype has not been examined. (See Fig. 15 for holotype).
Additional material examined: (3 males, 1 female): BOLIVIA: 1 female. TB# 20933 (FSCA). BOLIVIA: Santa Cruz: 1 male. TB# 20934 (ADSC). COLOMBIA: 1 male. TB# 20879 (FSCA).
Diagnosis: The supraorbital horns of this species are similar to those of H. brasilica, but do not curve inwards and are thicker than in that species. The clypeal horn is much thicker (three times as thick) as one supraorbital horn. All the horns are produced perpendicular to the head and continue without bending. The pronotum has punctures of two sizes. The coarse punctures are much larger and more distinct than in other species in this genus. The coarse punctures are scattered throughout the pronotum. Presently there is no identified female for this species. But it is assumed that, similar to other members of this genus, that the female will be similar in most characters except for the absence of the horns (Fig. 15).
Redescription: Male. Size: 8—9 mm; 3—4 mm.
Head. Clypeal horn long (4:1; 5:1), thick; somewhat flattened; three times thickness, at base, then one supraorbital horn (7:3); produced perpendicularly to head (8:1); finely punctate (9:1). Supraorbital horns long (10:1; 11:1), thin and are not curved laterally (12:0); not bent forward (14:0); produced perpendicularly to head (13:1); horns finely punctate (15:1). Antennae bearing stellate sensoria (22:0). Third antennomere less than 1.5 times size of fourth but more than 1.5 times size of second (18:1; 19:2). Vertex and frons punctate, punctures smaller than eye facet (26:1; 28:1). Gena not extending laterally past eye (36:0). Groove on mandible present, continuing to attachment point on cranium (44:1). Labrum fully setose (39:1).
Thorax. Pronotal puncturing biordinal in size (54:1); coarse punctures numerous and scattered over pronotum (57:2); coarse punctures more than two times size of fine punctures; in lateral view, pronotum not arched (58:0). Lateral margins of pronotum subparallel (61:1). Margins of pronotum expanded less than size of one coarse puncture (62:1). Anterior edge of pronotum not reaching middle of eye (63:0). Hypomeron laterally rugulose (75:2); not punctate; not pubescent (76:0). Mesepisternum with punctures larger than eye facets and separated by less than one diameter (71:2; 72:1). Prosternal process not continuing past posterior edge of pronotum (69:0). Elytra striate and punctate (46:1; 47:1); punctures separated by less than one diameter (48:0). Elytral interstices convex, and punctate (49:1); puncture size smaller than one fourth strial puncture size (50:1); punctures separated by more than one diameter (51:1).
Legs. Tarsi pubescent. Cuticular outgrowths present on proximal two protarsomeres (86:1). Apical spurs present on tibiae (85:1). More than seven socketed spines present on lateral edge of protibial (81:1). Brush of setae present on apex of tibiae (84:1).
Abdomen. Abdominal sternites punctate, first three abdominal sternites setose (94:3).
Distribution (Fig. 16): Brazil (Rio Grande do Sul), Columbia. A second male specimen was identified from comparison with the Holotype, despite being collected 3,000 miles away from the holotype.
