Chrysonotus dichrous Schiner, 1868 : 62 Schiner, 1868 : 62 Taxonomic revision of the Neotropical genus Himantigera James, 1982 (Diptera: Stratiomyidae: Sarginae), including the description of two new species and a key to the known species Fachin, Diego Aguilar Hauser, Martin Zootaxa 2018 2018-12-14 4531 4 451 498 (Schiner, 1868) Fachin & Hauser 2018 Schiner 1868 [151,542,1555,1581] Insecta Stratiomyidae Sargus GBIF Animalia Diptera 35 486 Arthropoda species dichrous comb. nov.  ( Fig. 132, A–E; A–C, holotype, NMW)     Chrysonotus dichrous   Schiner, 1868: 62(original description). Type locality: Venezuela(see comments below). Holotype ♀[NMW].   Diagnosis.This species can be easily distinguished from the other Neotropical  Sargusby an entirely metallic blue to purple abdomen ( Fig. 132) that strongly contrasts to the color of the thorax, which is mostly orange in both sexes except for an oval-shaped medial dark brown macula on the scutum, a dark brown ventral mark on the katepisternum, a medially dark brown laterotergite and a dark brown mediotergite with purple reflections in males ( Fig. 132, D–E). The fore and mid legs are mostly orange and the hind leg is often entirely dark brown, but it can be almost entirely orange on its femur and tibia. Male holoptic and female dichoptic, upper frons dark brown to black with metallic blue reflections, with a well-marked white callus frontally subdivided into two spots by a dark brown line in both sexes. Male often smaller and slender than females.   Material examined.

Squares represent holotypes, and circles paratypes and additional material.  Geographic distribution.  Colombia( Boyacá, Cauca, Cundinamarca) and Venezuela.   Comments.This species clearly belongs to the genus  Sargus. The color pattern of  S. dichrous( Schiner, 1868)  comb. nov.seems to be unique among Neotropical  Sargus,making it readily identifiable. Besides the records included here, there are additional females from Colombiain LACM. The typelocality of this species as indicated in the original description is “ Colombia”, but the label on the type( Fig. 132, A–C) reads “ Venezuela”. It was stated as being a male in Schiner (1868)and in Woodley (2001), but it is a female. 2117740476 [383,566,1661,1683] NMW Venezuela Venezuela 35 486 1 1 holotype 2117738906 [633,792,1376,1401] NMW Venezuela Lindig Alte Sammlung 39 490 1 1 holotype 2117744362 2000-03-11 2000-03-17 2000-03-11 LACM, USNM P.
