| Popis: | Chilicola (Oroediscelis) jaguense Packer and Dumesh, new species urn:lsid:zoobank.org:act: D3 B78728 -37FB-4BDE-B0C7-5090BF9B44D2 (Figs. 70���71, 143) Diagnosis. This is the only species in which the female has a yellow marking on the face. Additionally, the combination of: malar space 6.5 mm and T1 doubly punctate, serves to separate the female from all other species in the subgenus. It is most similar to C. huarpe Packer and Dumesh, n. sp., from which it can be differentiated based upon the yellow facial maculation, longer metapostnotal striae and longer malar space. Description. Female. Length 6.8 mm; forewing length 4.55 mm, head width 1.6 mm. Head: 1.2 X as long as wide, 99:81; black, yellow-orange mark above and below anterior tentorial pit, and on apical 1/3 of malar space. Face below antennae shining, weakly imbricate, most strongly on upper 2/3 of clypeus; clypeus and supraclypeal area deeply punctate, i=1���4 d; lower paraocular area deeply punctate, i=0.5���2 d; frontal area densely and evenly punctate, i~0.5 d; facial fovea shiny, punctures small to minute, widely separated; vertexal area coarsely punctate, punctures almost crowded. Malar space shorter than wide (8:11). Longest hairs on face above antennal sockets, 1.3 MOD, longer on vertex Mesosoma: pronotum and anteromedial portion of mesoscutum doubly punctate, small punctures dense, iMetasoma: terga shiny, shallowly imbricate; T1 doubly punctate scattered minute punctures among larger ones, i=1���3 d on disc; apical impressed area mostly densely punctate, i=1���2 d, apical 1/3 of area impunctate; T2��� T3 larger punctures denser, i=1���2 d; (remaining terga telescoped and not visible). Male: unknown. Material studied. Holotype female: ARGENTINA, La Rioja, Jag��e, 9.iii.1970, C. Porter & L. Stange, ���Entomofauna Subandina��� [IML] [See Figs. 184���185 for distribution map]. Etymology. The species is named after the type locality. Comments. The sole specimen is sufficiently distinctive to warrant description despite the fact that females of the subgenus are often difficult to separate.
