Hypogena amazonica ( Kulzer, 1962)

( Figs 11 View FIGURE 11 , 12 View FIGURE 12 )

Ulosonia amazonica Kulzer, 1962: 97 .

Type Material Examined: HOLOYPE (male) labeled: “Teffé (Ega) Amazones, M. de Mathan, 3. Trimestre, 1878” ( MNHN). ALLOTYPE (female) and PARATYPES (one male, one female) labeled same as HOLOTYPE. PARA- TYPE (male) labeled: (a) Teffé (Ega) / Amazonés / M. de Mathan / 3e Trimestre 1878”; (b) “ PARATYPUS / Uloso-

nia / amazonica / n sp. / det. H. Kulzer 1961”; (c) on blue paper “Tenebrionid Base / Aaron D. Smith / Catalog # 20135” ( NHMB). PARATYPE (female) labeled: (a) Teffé (Ega) / Amazonés / M. de Mathan / 3e Trimestre 1878”; (b) “ PARATYPUS / Ulosonia / amazonica / n. sp. / det. H. Kulzer 1961”; (c) on blue paper “Tenebrionid Base / Aaron D. Smith / Catalog # 20136” ( NHMB).” (See Fig. 11 View FIGURE 11 ) .

Notes: Several additional paratypes were described in Kulzer (1962), but not examined during the current study. These specimens should be in the Hungarian Natural History Museum ( HNHM) and the Muséum National d’Histoire Naturelle ( MNHN) .

Additional material examined. (5 males, 10 females): BRAZIL: Pará: 1 male. TB# 19670 ( RLAC) . BRAZIL: Rio de Janeiro: 6 females. TB# 19660-19664, 19671 ( BMNH) . BRAZIL: Rondônia: 1 female. TB# 20837 ( FSCA) . PERU: Amazonas : 1 male. TB# 19672 ( BMNH) . country not specified: 3 males, 3 females. TB# 19665-19669, 19673 ( BMNH) .

Diagnosis: Supraorbital horns thicker than in H. brasilica , arising perpendicularly from the head and then curve forward slightly, not as distinctly as in H. triceratops or H. laevicollis . The clypeal horn in this species is short, conical, and forward projecting. Males of this species bear a distinctive pointed process on the medial side of the proximal portion of the profemur, lacking in all other known Hypogena species. Pronotal punctures of two sizes present, coarse punctures scattered over the pronotum. Female specimens are similar to males, except without horns or profemoral process ( Fig. 11 View FIGURE 11 ).

Redescription: Male. Size. Length 7—8 mm, width 2.5— 3 mm.

Head. Clypeal horn short (4:1; 5:0), conical; base of clypeal horn twice as thick as one supraorbital horn (7:2); finely punctate (9:1). Supraorbital horns long (10:1; 11:1); produced forward (13:0); curving forward slightly after initially produced (14:1); finely punctate (15:1). Third antennomere 1.5x longer than 2nd or 4th antennomere (18:2; 19:2); antennae with stellate sensoria (22:0). Puncturing on vertex and frons smaller than eye facets (26:1). Gena not extending laterally past eye (36:0). Mentum trapezoidal (40:0), flat (43:0), punctate (42:1), and lightly setose (41:1); Labrum fully setose (39:1). Groove on mandible extending to connection point on cranium (44:1).

Thorax. Pronotal puncturing biordinal in size (54:1); coarse punctures numerous and scattered throughout pronotum (57:2). In lateral view, pronotum slightly arched (58:1). Lateral margins of pronotum subparallel (61:1). Edge of pronotum expanded less than diameter of one coarse puncture (62:1). Anterior edge of pronotum reaching past eye (63:2). Hypomeron laterally rugulose (75:2). Prosternum punctate (67:1); punctures not bearing short setae (66:0); separated by more than one diameter (68:0). Mesepisternum with punctures smaller than one eye facet and separated by less than one diameter (71:1; 72:1). Row of cuticular teeth present on posterior edge of metasternum (77:1). Elytra striate and punctate (46:1; 47:1); punctures separated by less than one diameter (48:0). Elytral interstices convex and punctate (49:1); punctures larger than one fourth strial puncture size (50:0); punctures separated by more than one diameter (51:1). Legs. Tarsi setose. Protarsi bearing cuticular spines on proximal two tarsomeres (86:1). Tibia with two apical spurs (85:1). On lateral edge protibia bearing more than seven socketed spines on distal third (81:1). No medial marginal spines on protibial (83:0). Medial edge of femur bearing a cuticular process (79:1).

Abdomen. First three visible abdominal sternites are laterally rugulose (89:1; 90:1; 91:1). All abdominal sternites punctate; first three sternites coarsely punctate. First three abdominal sternites setose; setae arising from punctures (94:2). Remaining sternites finely punctate.

Female. Similar to male, except as follows: Clypeal and subraorbital horns absent; intraocular space extending transversely inwards (23:2); intraocular space impinging on eye (24:1). Puncturing on vertex smaller than eye facet (25:1). Puncturing on frons smaller than eye facet (27:1). Clypeus finely and evenly punctured on clypeus (31:1). Anterior edge of clypeus flat; anterior corners rounded (30:1); clypeus tumid (33:1). Cuticular process not present on medial edge of profemur.

Distribution ( Fig. 12 View FIGURE 12 ): Brazil (Pará, Rondônia, Amazonas, Rio de Janeiro), Peru (Amazonas).
