Subgenus Chilicola Spinola s. str.

Chilicola Spinola, 1851, Hist. Fis. Pol. Chile. Zool. Type Species: C. rubriventris Spinola, 1851, designated by Sandhouse, 1943

Diagnosis. The following unique characteristics allow species of the subgenus Chilicola s. str. to be differentiated from related subgenera: face slightly concave in lateral view [Fig. 14I; Chilicola (Chilioediscelis) has erroneously been reported to also have a concave face (Michener 1995, 2000)], distal margin of clypeus curved around lateral margin of labrum (Fig. 14B), S6 of females with apical spine (Fig. 15 L), mesepisternum and S2 of males with dense pubescence (Figs. 12D, 12H respectively), S7 of males with curved, apically oriented dorsal process (Figs. 1–6, 16B), Chilicola s. str. and C. (Chilioediscelis) share the following: vertex sometimes concave (Fig. 14 K), hind tibial spurs robust and curved (Fig. 15F), frons of females with longitudinal striae (Fig. 13D), fore femur of males robust, and spiculum moderately broad and long (Fig. 16D). Chilicola s. str. displays the following plesiomorphies that differentiate it from C. (Chilioediscelis): male clypeus with granulose sculpture (Fig. 12K), pronotal lobe entirely black (Fig. 10A), episternal groove extends below scrobal groove (Fig. 13H), inner tooth of hind claw well developed (Fig. 15G), and S2 scopa of females corbiculate (Fig. 12I).

Description. Black-brown; males with variable patterns of yellow on face and legs except anterior surface of male fore tibia always yellow (Figs. 10E) and fore and mid distitarsi always yellow-orange; females often with orange-red on metasoma (Fig. 11H); face slightly concave; distal margin of clypeus curved around lateral margin of labrum; head broader than long; eyes convergent below; clypeus broader than long; frons with slight depression above antennal sockets; episternal groove extends below scrobal groove; hind femur of males robust with broad concavity on ventral surface continuous with flattened ventral surface of hind trochanter; hind tibial spurs robust and curved; hind tibia of some males expanded with ventral concavity (Figs. 1E, 2C, 4E, 5C); S1 of males with or without ventrally oriented process (Figs. 15I, J); males with dense hairs on S2; females with weak hind leg scopa; S2 of females with corbiculate scopa; microsculpture granular; punctation variable except dense on lower and upper paraocular areas and frons; S6 of females with apical spine; S7 of males with two lateral lobes, dorsal lobes curved, apically oriented (Figs. 1–6); S8 with long, moderately broad spiculum; penis valve with pair of large, dorsal, membranous appendages (Figs. 1–6).
