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
).
