Chilicola (Oroediscelis) capillitas Packer and Dumesh, new species urn:lsid:zoobank.org:act: D1B5000A-338E-4BE1-8684-8D7A913DE892 (Figs. 5–11, 84, 149, 151) Diagnosis. The male of C. capillitas can be differentiated from those of all other species of C. (Oroediscelis) by the combination of: yellow marks on clypeus present; processes on S5 absent; and form of the processes on S4 which are long, comparatively straight, not apically concave and, in profile, slightly concave ventrally towards the apex which is produced slightly ventrally and weakly hook-like. Other species with yellow on the clypeus, lacking processes on S5, and with long processes on S4 have the latter bent ventrally and diverging apically (C. cuzcoensis Michener), apically concave (C. styliventris Friese, C. abrebotellas Packer and Dumesh, n. sp., C. fritzi Packer and Dumesh, n. sp.), or with processes relatively short and flat apicoventrally (C. rozeni Packer and Dumesh, n. sp.). The female can be differentiated by the combination of: malar space approximately 3/4 as long as wide; metapostnotum with nearly all striae surpassing midlength; and punctures on vertexal area large and dense. Description. Male: Length 6.5 mm; forewing length 4.5 mm, head width 1.6 mm. Head: about 1.1 X as long as wide, L:W 91:81. Clypeus with apical yellow band, paraocular area yellow to above level of dorsal margin of clypeus, mandible with basal yellow maculation (variable in size). Clypeus and supraclypeal area punctures small, distinct, irregularly spaced, i=1–4 d and i=0.5–4 d respectively; lower paraocular area punctures sparse below, i~d above; frontal area deeply alveolate-punctate. Clypeus with weak longitudinal depression. Malar space 3/4 as long as wide (9:12); lower ocular tangent above middle of clypeus. Longest hairs on face 3 MOD; genal beard with hairs 4 MOD posteriorly. First flagellomere as long as second on anterior surface (12:12) but longer on posterior surface (15:12); F2 and F3 with one subapical seta as long as succeeding flagellomere and one approximately half as long. Mesosoma: pronotum finely, densely punctate; mesoscutum and mesoscutellum punctures distinct, mostly i=0.5–1d, with a few larger interspaces on discs; metanotum irregularly punctate, i=0.5–2 d; mesepisternum punctures i~d, sparser above scrobal groove; metepisternum longitudinally striate above, shiny weakly microsculptured below; obscurely, sparsely punctate throughout. Metapostnotum shorter than mesoscutellum (17:20); with fine, longitudinal, irregular, sometimes anastomosing and interrupted striae; lateral surface of propodeum coarsely imbricate; weakly, sparsely punctate. Longest hairs of mesosoma 3.5 MOD, on mesepisternum, metanotum laterally and dorsolateral area of propodeum; longest hairs on mesoscutum ~1.4 MOD. Stigma shorter than marginal cell on wing margin (35:47), distal stigmal perpendicular slightly apical to first submarginal crossvein. Metafemur with posteroventral margin sharp. Metatibia more than 3X as long as greatest depth, 64:19, which is at apex of apical tooth of posterior crest; subapical brush incomplete; bare area of ventral surface shining, without microsculpture; posterior crest mostly straight, ending in a strong, acute tooth; anterior crest evenly rounded in anterior view. Metabasitarsus shorter than remaining tarsomeres combined (44:55), ventral process at basal 1/4, anterior process at midlength, apex of anterior process somewhat obtuse to somewhat acute (the two sides of the holotype vary). Metasoma: somewhat dull due to microsculpture except apical impressed areas shiny; punctures distinct, i~d on disc, apical impressed areas finely punctate to close to apex, i=1–2 d; apicolateral patches of white, plumose hairs on T1–T3. S1 longest hairs posteriorly, 2.2 MOD; S2 longest hairs anterolaterally, 3 MOD; S3 apicolateral erect hairs <2 MOD; S4 long hairs anterolaterally, 3 MOD; S5 long hairs anterolaterally, 4 MOD; apical fringe of robust setae absent; S6 hair tuft ~2 MOD. S2 with weak and S3 with strong sublateral bosses; processes of S4 long, <4 MOD, subparallel in ventral view, inner margins slightly curved laterad; in profile, ventral surface straight except weakly concave for apical 1/3, apex pointed; S5 unmodified; S6 apicolateral fovea 3X longer than wide, mesal margin raised, surface of disc concave; apical impressed area distinct, membranous, long, 1.1 MOD, hair fringe subequal in length to apical impressed area. Terminalia: refer to Figs. 7–9. Female: As in male except for usual secondary sexual characteristics (number and form of flagellomeres, number of metasomal terga and sterna, terminalia, and leg and sternal modifications in males) and as follows: Length 6.5 mm, forewing length, 5 mm, head width 1.6 mm. Face and mandibles black. Frontal area distinctly punctate, i
