Mycolybas rufipennis Guerin 1956

Mycolybas rufipennis Guérin, 1956 (Fig. 8, 9, 17, 18, 20, 23, 53, 54, 59) Mycolybas rufipennis Guérin, 1956: 63; Alvarenga 1994: 44 [cat.]. Holotype: Brazil—Amazonas: Manaus, J. Guérin col., J. Guérin det. 1954 (MZSP—examined). Etymology: rufus— reddish brown, Greek, and pennis— wing, Greek. Epithet refers to reddish brown elytra (Guérin 1956). Diagnosis: elytra ruby scarlet (RS- 5 - 3 °), head and pronotum dark brown (S- 1-12 °— fig. 8). Seven elytral striae, the most external absent on anterior third, punctation diameter ~0.02 mm (fig. 53, 54). Pronotal median lobe not truncate at scutellum, scutellum dark brown (fig. 8, 18); prosternal suture incomplete (fig. 9, 59); sternum, legs and abdomen dark brown (fig. 9); meso- and metacoxal lines present (fig. 59). Redescription: Length: 8 mm; thorax-abdomen: r = 0.4. Body ovoid (fig. 8, 16), strongly convex (fig. 12, 17). Elytral pubescence absent. Head (fig. 20): antennae (fig. 23) dark brown; club wide, flattened, with three antennomeres. Thorax (fig. 8, 9, 17, 18, 59): pronotum: r = 0.6, prominent anteriorly; prosternum: procoxal lines absent. Scutellum: r = 0.5. Metasternum (fig. 59): r = 0.3, supracoxal lines present, metepisterna: r = 3.1. Legs (fig. 9, 59): tibiae slightly expanded distally. Elytra (fig. 53, 54): r = 2.2. Material examined: Holotype only. Intraspecific variation: Unknown. Geographical distribution: Brazil (Amazonas). Discussion: Mycolybas rufipennis exhibits characters otherwise atypical of Mycolybas (absence of coxal lines, truncate base of scutellum and tibiae moderately expanded distally). However, M. rufipennis remains in Mycolybas until a comprehensive phylogenetic analysis is completed.Published as part of Lopes, Peterson Lásaro, 2006, Taxonomic revision of Mycolybas Crotch, 1876 (Coleoptera: Erotylidae), pp. 1-35 in Zootaxa 1373 on pages 29-30, DOI: 10.5281/zenodo.17495

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 °).

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.Published as part of Lopes, Peterson Lásaro, 2006, Taxonomic revision of Mycolybas Crotch, 1876 (Coleoptera: Erotylidae), pp. 1-35 in Zootaxa 1373 on pages 30-31, DOI: 10.5281/zenodo.17495

Intraspecific variation: Integument color varies from orange red (from SSO- 7-11 ° to SSO- 9-12 °), scarlet orange (SO- 8-12 °), reddish orange (OOS- 8 - 7 ° and OOS- 10 - 8 °), to orange (O- 14 - 8 ° and O- 15 - 10 °), sometimes with a thin pale strip on elytral and pronotal margins, and pronotal color slightly stronger than elytral; some exemplars show slightly darker legs, whereas others have apical darkening on the elytra. Several have the 10 th stria, with more scattered punctation than the ninth. Striae sometimes more evident, with punctation diameter ~0.04 mm. Geographical distribution: Honduras (Francisco Morazán), Costa Rica (Guanacaste, Heredia, Limón, San José), Panama (Chiriqui), Colombia (Cundinamarca), Brazil (Amazonas, Pará, Bahia, Mato Grosso, São Paulo, Rio de Janeiro, Paraná, Santa Catarina, Rio Grande do Sul), Peru, Paraguay (Alto Paraná, Cordillera, Caazapá, Itapúa), Argentina (Misiones). Discussion: morphological similarity between M. lucidus, M. cruentatus and M. egae was noticeable. After comparisons among the antennal color, elytral punctation, body size and shape and other structures, these species were determined to be synonymous. The main diagnostic character for M. melanocorynus is the laterally-expanded tarsomeres, also found in males of M. lucidus. After comparing holotypes and identified material of both species, and specimens of M. melanocorynus being mostly males (except for a female identified by K. Delkeskamp), M. melanocorynus was determined to be synonymous with M. lucidus.Published as part of Lopes, Peterson Lásaro, 2006, Taxonomic revision of Mycolybas Crotch, 1876 (Coleoptera: Erotylidae), pp. 1-35 in Zootaxa 1373 on pages 24-29, DOI: 10.5281/zenodo.17495
