Polietina prima

Polietina prima (Couri & Machado, 1990)

Cyrtoneurina prima Couri & Machado, 1990: 659. Holotype female (MNRJ); six paratypes females (MNRJ). Type locality: Represa dos Ciganos (Parque Nacional da Tijuca), Rio de Janeiro, Brazil.

Polietina nigra Couri & de Carvalho, 1996: 825. Holotype male (MNRJ), 15 paratypes females (MNRJ). Type locality: Una, Bahia, Brazil. Syn. nov.

Remarks. Polietina prima was described by Couri & Machado (1990) in Cyrtoneurina Giglio-Tos, 1893 based on seven females collected in Represa dos Ciganos (Parque Nacional da Tijuca), Rio de Janeiro. Couri & Pamplona (1997) transferred these species to Polietina and re-described it based on type-material (MNRJ). Nihei & de Carvalho (2007: 489) included a short description of the male of P. prima, indicating that marginal spines process of cercal plate has downwardly orientated spines. Polietina nigra was described based on 16 specimens, 1 male (holotype) and 14 females (paratypes), from Una, Bahia and 1 female (paratype) from Rio de Janeiro. For the present manuscript, we analyzed male specimens previously identified as P. nigra and P. prima. We are not able to find any conspicuous difference between them. The examined male genitalia of both species is very similar to drawings made by Couri & de Carvalho (1996: figs. 1 – 5), even when compared with figures of phallus and associated structures in Nihei & de Carvalho 2003: figs 1 – 2, where slight difference can be seen in the shape of pregonite. Also, the ovipositor of Polietina prima and Polietina nigra are very similar (Couri & Machado 1990: fig. 2; Couri & Carvalho 1996: figs. 6 – 7). The only difference in adult chaetotaxy is a variation of the number of setulae on the anteroventral face of the hind tibia, which is used in the key for the identification of species (Nihei & de Carvalho 2007). In the present study, this is considered an intraspecific variation.

Polietina prima has a wide area of distribution (Löwenberg-Neto & de Carvalho 2013), and all specimens were collected in forested sites. It is a synanthropic species collected with banana mixed with ‘ rapadura’, a Brazilian sweet made from sugar cane (D’Almeida 1993). Polietina prima is larviparous, with third instar larvae found in the female abdomen (Couri & de Carvalho 1996).
