Taxonomic revision of Mycolybas Crotch, 1876 (Coleoptera: Erotylidae) Author Lopes, Peterson Lásaro text Zootaxa 2006 1373 1 35 journal article 10.5281/zenodo.174955 52ea66ac-64b3-4d2f-b228-7fa4671f902f 1175-5326 174955 Mycolybas sanguinosus ( Motschulsky, 1858 ) ( Fig. 10 , 19 , 20, 24 , 49, 50 , 60 ) Ischyrus sanguinosus Motschulsky, 1858 : 116 . Holotype : Colombia (ZMUM—not examined). Mycolybas sanguinosus : Crotch, 1876 : 474 ; Gemminger & Harold 1876 : 3691 [cat.]; Kuhnt 1909 : 91 , 1911: 67; Blackwelder 1945 : 468 [chkl.]; Alvarenga 1994 : 44 [cat.] Mycolybas sanguinosa : Blackwelder 1945 : 468 [chkl.] Etymology: sanguinosus— blood red, in Latin, and pennis— wing, in Greek. The name refers to the reddish elytra and pronotum, according to the original description ( Motschulsky 1858 ). Diagnosis: Elytra orange red (SSO-6-9°), pronotal color stronger (fig. 10). Body oval (fig. 12, 15, 19), slightly convex (fig. 11). Nine elytral striae, the most external absent on the anterior third, punctation very small (fig. 49, 50). Pronotal median lobe not truncate at scutellum (fig. 10, 19); legs scarlet orange (SO-7-10°—fig. 10); pro-, meso- and metacoxal lines present (fig. 60). Redescription: length: 5 mm ; thorax-abdomen: r = 0.7. Sternal color lighter and less strong than elytral or pronotal. Elytral pubescence absent. Thorax (fig. 10, 19, 60): pronotum: r = 0.5; prosternum: prosternal suture complete. Scutellum: r=0.6. Sternum scarlet orange (SO-7-12°). Metasternum: r = 0.4, supracoxal lines present, metepisterna: r=5.0. Legs (fig. 12, 19): tibiae slightly expanded distally. Elytra (fig. 49, 50): r = 2.4. Abdomen: scarlet orange (SO-7-10°). Material Examined: Colombia— one exemplar, possibly syntype ( ZMUM ). Intraspecific variation: Unknown. Geographical distribution: Colombia . Discussion: Mycolybas sanguinosus does not match at least some characters of the genus (absence of coxal lines, truncate base of scutellum and tibiae moderately expanded distally). However, M. sanguinosus remains in Mycolybas until a comprehensive phylogenetic analysis is completed.
