Peckia (Euboettcheria) anguilla (Curran & Walley, 1934)

(Figs 5, 39–44)

Description of female terminalia. Posterior margin of T5 elliptical, brown, with golden microtrichosity dorsally and silver spots laterally (Figs 42–44). T6 divided into two halves, orange with a row of setae near posterior margin. Spiracle 6 located on intersegmentary membrane, spiracle 7 located on T6. T8 absent (Fig. 39). Epiproct undivided, covered with long and fine setae. Cercus covered with long and fine setae. Hypoproct represented by a triangular membranous area covered with fine, long setae (Fig. 40). ST6 rectangular, covered with setulae and with a row of setae near posterior margin. ST7 square, with fine small setae near posterior margin. ST8 triangular, covered with fine small setae (Fig. 39). Spermathecae rounded (Fig. 41).

Material examined. BRAZIL. Espirito Santo: Novo Horizonte, Conceição da Barra, X.1972, leg. Alvarenga & Roppa (1 ♀, MNRJ). Pará: Almeirim, Jari, 8.XII.2006, on rotting beef lung, leg. T. Gardner (5 ♂♂, MPEG). Rio de Janeiro: Angra dos Reis, 11.XII.1972, leg. H.S. Lopes (1 ♀, MNRJ); same data but 1.IV.1972 (1 ♀, MNRJ).

Distribution in Brazil. Amazonas, Ceará, Distrito Federal, Espírito Santo, Mato Grosso, Minas Gerais, Pará, Paraná, Rio de Janeiro, Roraima, São Paulo.

Remarks. The female terminalia of P. (E.) anguilla and P. (E.) collusor are morphologically similar since they both have T5 with an elliptic posterior margin, spiracle 6 located on the intersegmentary membrane and spiracle 7 located on T6 (Figs 39, 42, 45, 48). However, P. (E.) anguilla differs from P. (E.) collusor in having ST8 triangular while in P. (E.) collusor it is oval, reduced and joined to ST7 by a membranous region (Figs 39, 45).

Peckia (E.) anguilla has a wide distribution, but it is uncommon and has usually been collected with traps baited with bovine lung in Brazil’s Amazonian forests (Dias et al. 1984; Carvalho-Filho & Esposito 2009; Sousa et al. 2011, 2015). It is associated with forested environments (Dias et al. 1984).
