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).
