New synonymy in Platyphora Gistel (Coleoptera, Chrysomelidae, Chrysomelinae)

Abstract

New synonymy in Platyphora Gistel (Coleoptera, Chrysomelidae, Chrysomelinae). Doryphora cliensStål, 1858 is considered a synonym of Doryphora congenerStål, 1858.

Keywords:
Beetles; Chrysomelini; Insecta; Taxonomy

The genus PlatyphoraGistel, 1857 presents 452 species distributed from Mexico to Argentina and 182 species occur in Brazil (Blackwelder, 1946; Daccordi, 1994; Sekerka, 2016). The study of the type specimens of Platyphora allows us to propose a new synonymy in P. congener (Stål, 1858).

The original descriptions of Doryphora congener and Doryphora cliensStål, 1858 are very similar and only some differences were related to the color of the elytra and ventral region. The comparisons of the holotype photos of D. congener (Figs. 1,2) and D. cliens (Figs. 4,5), deposited in NHRS, and the comparative examination of 48 specimens helped us to observe that the differences between these species are only due to intraspecific variation (Figs. 1-6, 11-16). Also, the male genitalia of specimens from different localities (Espírito Santo, Rio de Janeiro and São Paulo) were dissected and no differences were observed. Therefore, Doryphora cliens is here considered a synonym of Doryphora congener.

Platyphora congener (Figs. 1-3, 11-16) is similar to Platyphora histrio (Olivier, 1807) (Figs. 7, 9) and Platyphora circumflexa (Stål, 1857) (Figs. 8,10) and differs by projection of the mesosternal process well developed, enlarged and not curved and by the elytra with a narrow yellow stripe restricted to the outer margin. In P. histrio and P. circumflexa the projection of mesosternal process is shorter and curved. In P. histrio the lateral and anterior margins of elytra present a narrow yellow stripe. P. circumflexa presents two stripes on lateral margins of elytra, one external yellow and another internal, black.

Geographical distribution. Brazil (Espírito Santo, Minas Gerais, Rio de Janeiro, Santa Catarina, São Paulo).

Type material. We examined the holotype photos of P. congener (Figs. 1-3) from Brazil, and P. cliens (Figs. 4-6) from Brazil and P. circumflexa (Figs. 8,10) from Bahia, Brazil, taken by Dr Johannes Bergsten (NHRS) and the syntype of Platyphora histrio (Figs. 7,9) from Brazil taken by Dr. Antoine Mantilleri (MNHN).
