description: Chilicola (Chilicola) pangue Toro and Moldenke
Chilicola (Chilicola) pangue Toro and Moldenke, 1979. An. Mus. Hist. Nat. Valparaíso 12:103. Male.
Diagnosis: The male of C. pangue is the only member of this subgenus to have a clypeus that completely lacks yellow colouration (Fig. 5A). This species is very similar to C. rubriventris but can be differentiated by clypeal colouration and S7, the dorsolateral lobe of which has a tapered apex in C. pangue (Fig. 5E) but is clavate in C. rubriventris (Fig. 1G). Females of C. pangue are unknown.
Description: Male: Length 8mm, forewing length 5.0mm, head width 1.9mm.
Colouration: Black-brown with following parts yellow: mandible dorsally for basal half, apex orange-red; lower paraocular area proximal to epistomal suture with small spot (Fig. 5A); femoral apex and tibial base of all legs; anterodorsal surface of fore tibia; mid trochanter with yellow-orange apex; fore and mid distitarsi; apicoventral surface of hind tibia; basoventral surface of hind basitarsus; ventral surface of flagellomeres orangebrown; apical impressed areas of T1-T3 testaceous; tegula brown; wing venation brown except for testaceous basal regions of R, M+Cu, and V.
Pubescence: Long and coarse on mandible, face, gena (longest medially), and vertex (1-3OD, OD= 0.165mm); flagellomeres with short setae and long, sparse setae on dorsal surface; sparse dorsally on thorax except near lateral margins (2OD); long on lateral surface of thorax especially ventrally and on posterior surface of propodeum (2-3OD); apical impressed portions of T1-T5 with sparse hairs, denser laterally (<1.5OD); dense ventrally oriented hairs on S1, laterally on S2-S3 (<2OD); moderately dense hairs on fore and hind coxa and hind femur (1-2OD); curved hairs on fore tarsus (~1.5OD).
Surface sculpture: Microsculpture granular, surface moderately dull except face below antennae moderately shiny; clypeus granulose with fine, sparse punctures except laterally (i=1-3d); dense punctures on lower and upper paraocular areas and frons (i~d); surface of frons irregularly striate; punctures very dense on dorsal surface of thorax (i<d); moderately dense on lateral thoracic surface (i=1-2d); dorsal area of propodeum reticulate anteriorly with coarse, longitudinal striae posteriorly; punctures on terga moderately dense (i=1-2d).
Structure: Head broader than long (95:75); IOC slightly larger than OOC (19:17); eyes convergent below, UOD:LOD (62:45); clypeus broader than long (68:46); dorsal margin of labrum broadly concave; vertex slightly convex behind ocellar triangle in frontal view; frontal line above supraclypeal area carinate; weak, median, longitudinal groove on clypeus; ratio of lengths of pedicel:F1-F3 — 13:13:16:18; gena more than half as wide as compound eye in lateral view (14:24); relative lengths of scutellum: metanotum: dorsal area of propodeum — 25:13:16; maximum length to maximum depth of hind femur — 63:35; hind tibia with anteroventral margin expanded (Figs. 5C, D), maximum length, width, depth — 45:15:22, maximum depth immediately basal to strong preapical concavity; apex of hind tibia with transverse lamina; length of hind tibia, hind basitarsus — 34:21; S1 with apically concave process; S7 ventrolateral lobes moderately broad with apical concavity, dorsolateral lobes moderately long, tapered apically (Fig. 5E); S8 lateral lobes with basally oriented spines, spiculum with bifurcate apex (Fig. 5F); gonoforceps elongate (Fig 5G).
Material Examined: CHILE, Region IV, Coquimbo (El Pangue), 1400m, 24.viii.1956, collector not known, holotype male (AMNH).
Geographic Distribution: This species is known only from the type locality and type specimen above (Fig. 7).
Comments: This species is apparently very rare and is only known from the holotype. The type locality is frequently visited by collectors, although usually not so early as late August. The correct area was visited by A. Ugarte P. in early September, 2004 and although bees were collected from Adesmia bushes, no C. pangue were found. The holotype was collected almost 50 years before this revision and no new specimens are known to have been collected since.
