Chilicola (Chilicola) aisenensis Toro and Moldenke

Abstract

Chilicola (Chilicola) aisenensis Toro and Moldenke Chilicola (Chilicola) aisenensis Toro and Moldenke, 1979. An. Mus. Hist. Nat. Valparaíso 12:102. Male Diagnosis: C. aisenensis males have a clypeus with an inverted T-shape mark similar to that of C. rubriventris (Fig. 2B). The hind tibia of C. aisenensis has the expanded ventral margin, preapical concavity, and apical transverse lamina common to most other members of the subgenus. The hind tibia can be differentiated from those of C. rubriventris, C pangue, and C. luzmarieae by the expanded ventral margin that forms a smooth convex curve, thickest at midlength and gradually tapers to the preapical concavity (Fig. 2C). The male of C. aisenensis also lacks the process on S1 that is present in C. colliguay, C. pangue, and C. rubriventris but is somewhat swollen as in C. luzmarieae and C. venticola. Females are unknown. Description: Male: Length 5.9mm, forewing length 3.8mm, head width 1.6mm. Colouration: Black-brown with following parts yellow: labrum; base of mandible; inverted T-shape on clypeus (Fig. 2B); lower paraocular area to just below antennal socket medially, to below epistomal suture laterally (Fig. 2B); dot on apicoventral surface of scape; anterior spot on tegula (remainder pale straw); apex of fore and mid femur; fore tibia except ventral surface suffused with brown; fore tarsus; apex and base of mid tibia and ventral surface suffused with brown; basoventral surface of mid basitarsus; base and apex of hind tibia and along anteroventral margin (Figs. 2C, D); base of hind basitarsus; dorsal surface of fore and mid trochanter with yellow-orange apex; ventral surface of antenna orange-brown from apical half of pedicel to terminal flagellomere; anterior margin of apical impressed areas of T1-T7 testaceous; wing venation brown except for testaceous basal regions of R, M+Cu, and V. Pubescence: Long and thick on face and gena (1-3OD, longest medially; OD~ 0.14mm), with dense, short hairs on vertex (~1.5OD); flagellomeres with short setae; pronotum with short (
