Diagnosis: The male of this species has two short conical horns that arise from between the eyes and a very short clypeal horn. These horns project forward, parallel to the body. The clypeal horn may be absent or simply a tubercle projected forward at the anterior edge of the clypeus. The pronotal punctures for this species are of two sizes and the coarse punctures are scattered throughout the pronotum. The prosternum does not bear setae. The female is similar in most regards, except for the presence of the horns ( Fig. 32 View FIGURE 32 ).

Redescription: Male. Size: 6—7 mm; 2—3 mm.

Head. Clypeal horn short (4:1; 5:0). equal thickness to supraorbital horns (7:1); projected forward (8:0). Supraorbital horns short, barely reaching past eye (10:1; 11:0); projected forward (13:0); not bent after initial production (12:0; 14:0); finely punctate (15:1). Vertex and frons punctate; punctures smaller than eye facets (26:1; 28:1). Antennae bearing stellate sensoria (22:0). Third antennomere of same size as fourth and more then 1.5 times size of second (18:0; 19:2). Gena not extending laterally past eye (36:0). Clypeus pointed from production of clypeal horn (29:2). Mentum trapezoidal, flat and lightly setose (40:0; 43:0; 41:1). Labrum fully setose (39:1). Groove on mandible present, continuing to connection point to cranium (44:1).

Thorax. Pronotal puncturing biordinal in size (54:1). Coarse punctures numerous; scattered throughout prono- tum (57:2). From lateral view, pronotum not arched (58:0). Lateral margins of pronotum subparallel (61:1). Margin of pronotum expanded more than diameter of one coarse puncture (62:2). Row of cuticular teeth present on posterior edge of metasternum (77:1). Anterior edge of pronotum reaching middle of eye but not past eye (63:1). Prosternum punctate; punctures smaller than eye facet (67:1); separated by less than one diameter (68:1). Hypomeron laterally rugulose (75:2). Mesepisternum punctate; punctures smaller than eye facet (71:1); separated by more than one diameter (72:0). Elytra striate and punctate (46:1; 47:1); punctures separated by more than one diameter (48:1). Elytral interstices convex and punctate (49:1); punctures larger than one fourth strial puncture size (50:0); separated by less than one diameter (51:2).

Legs. Tarsi pubescent. Cuticular outgrowths present on proximal two protarsomeres (86:1). Tibiae with two apical spurs (85:1). Lateral edge of protibia with seven or more socketed spines on distal half (81:1; 82:1). Apex of tibiae with brush of setae (84:1).

Abdomen. First three visible abdominal segments weakly laterally rugulose (89:1; 90:1; 91:1). All abdominal sternites punctate. Punctures on first four abdominal segments coarsely punctate; Last abdominal sternite finely punctate. All abdominal sternites with setae arising from punctures; setae longer on first abdominal segment than on last (94: 3).

Female. Similar to male, except as follows: Cuticle on intraocular space narrowly raised near eye (23:1); Intraocular space impinging on eye (24:1). Clypeus with punctures smaller than eye facets and spread evenly across clypeus (31:1; 32:2). Anterior edge of clypeus flat with corners rounded (30:1). Clypeus tumid (33:1).

Distribution ( Fig. 33 View FIGURE 33 ): Peru (Lima), Guatemala, USA (Texas, California, Arizona), Costa Rica, Mexico (Sonora, Colima, Baja California, Veracruz, Tamaulipas, Nuevo León, Baja California Sur).
