Trigonopeltastes aurovelutinus Curoe, 2011

Remarks.

The male of this species was previously unknown so a description of the key characters is given below. One male specimen was examined labeled "Mex: Guerrero / Acuhuezotla / IX-29-94 Chemsak" (EMEC).

Description of male

(Figs 46-51). Color: similar to the description of the females ( Curoe 2011; Figs 46-47); dorsal surface black except elytra uniformly orange with darker sutural line. Legs orange with black tarsi and metatibia (Fig. 47). Head: Surface glabrous except for light, setose patches at base of clypeus and apex of frons, without cretaceous markings (Fig. 50). Pronotum: Surface of disc dull-black with shiny micropunctures (Fig. 50); setae scattered across disc but not obscuring surface as seen in the Curoe (2011) figure of the female (perhaps due to abrasion). Marginal bead complete; with thick, scale-like setae. Pronotal disc with more-or-less complete inverted triangle indented into the surface with thick scale-like setae (Fig. 50). Elytra: Orange, glabrous, without cretaceous markings (Figs 46-47). Pygidium: Surface with white, scale-like setae covering disc (but not obscuring surface, perhaps due to abrasion), without cretaceous makings (Fig. 49). Venter: Surface covered with white, scale-like setae. Visible abdominal sternites with erect, white setae scattered medially. Legs: Protibia with 2 teeth near apex (Fig. 47) (female with third medial tooth; Curoe 2011). Metatibia with a distinct, medial protuberance along inner surface (Fig. 46), surface distad to this protuberance smooth with fine striations that may be for stridulation (a key diagnostic character not found in male Trigonopeltastes simplex and not apparent in the description and figure of the female Trigonopeltastes aurovelutinus ). Parameres: Robust with lateral notches towards apex (Figs 48, 51).
