Diagnosis: The male of this species can be readily identified by the three long, thin, erect horns that are placed between the eyes and on the clypeus. The horns are equal in length and thickness. This species is also distinctive in the coarse punctures on the pronotum are almost always closely concentrated in the center of the disc. The female is similar in all respects, except that the horns are not present and the frons is more punctate ( Fig. 36 View FIGURE 36 ).

Redescription: Male. Size: 7—8 mm; 2—3 mm.

Head. Clypeal horn long, thin (4:1; 5:1); not emarginated (6:0); equal in thickness to one supraorbital horn (7:1); equal in length to supraorbital horns; produced perpendicular to head (8:1); not curved; finely punctate (9:1). Supraorbital horns long, thin (10:1; 11:1); bent slightly inwards (12:1); produced perpendicular to head (13:1); not curved forward (14:0); finely punctate (15:1). Antennae with stellate sensoria (22:0); third antennomere same size and fourth and more than 1.5 times size of second (18:0; 19:2). Vertex and frons of male almost smooth (26:0; 28:0). Anterior edge of clypeus flat with corners rounded (29:1). Mentum trapezoidal, flat, punctate and lightly setose

(40:0; 43:0; 42:1; 41:1). Labrum fully setose (39:1). Groove on mandible present, continuing to connection point to cranium (44:1).

Thorax. Pronotum with puncturing biordinal in size (54:1); coarse punctures concentrated primarily on disc (57:1). Lateral margins of pronotum subparallel (61:1). Marginal edges of pronotum expanded more than one coarse puncture’s diameter (62:2). Anterior edge of pronotum reaching middle of eye, but not past middle of eye (63:1). Short setae on prosternum arising from punctures (70:1); puncturing on prosternum smaller than one eye facet (67:1); prosternal punctures separated by less than one diameter (68:1). Hypomeron laterally rugulose (75:2). Mesepisternum punctate; punctures smaller than eye facets (71: 1); separated by more than one diameter (72:0); not setose (73:0). 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 of strial puncture size (50:0); separated by more than one diameter (51:1).

Legs. Tarsi pubescent. Cuticular outgrowths present of proximal two protarsomeres (86:1). On lateral edge of protibia, seven or more socketed spines on distal third of protibial (81:1; 82:0). Medial edge of protibial with entire length (83:1). Apex of protibia bearing brush of setae (84:1).

Abdomen. First three visible abdominal segments laterally rugulose (89:1; 90:1; 91:1); fourth and fifth abdominal sternites punctate. All abdominal segments setose (94:3); setae arising from punctures.

Female. Similar to male, except as follows: Intraocular space raised and extending transversely inwards (23:2); intraocular space impinging on eye (24:1). Punctures of vertex and frons smaller than eye facet (25:2; 27:2). Clypeal punctures smaller than one eye facet spread evenly across clypeus (31;1; 32:2). Clypeus tumid (33:1).

Distribution ( Fig. 37 View FIGURE 37 ): Cuba, Trinidad, Mexico (Chiapas, Nuevo León, Yucatan, San Luis Potosi, Tamaulipas, Veracruz, Sonora, Puebla, Baja California Sur, Oaxaca, Nayarit), Belize, Panama ( Panama), Venezuela (Bolivar, Zulia), Columbia, Ecuador (Guayas), Cayman Islands, Costa Rica (Guanacaste, Heredia), El Salvador (San Salvador), USA (Texas, Florida), Guatemala (Escuintla, Petén). The type material is from Jamaica.
