Peckia ( Euboettcheria) collusor ( Curran & Walley, 1934) View in CoL

( Figs 11–12 View FIGURES 11–20 , 45–50 View FIGURES 45–50 , 119 View FIGURES 117–120 )

Description of female terminalia. Posterior margin of T5 elliptical, brown, with golden microtrichosity ( Figs 48– 50 View FIGURES 45–50 ). T6 divided and with posterior margin separated, orange with a row of setae near posterior margin ( Figs 45, 48 View FIGURES 45–50 ). Spiracle 6 located on the intersegmentary membrane, spiracle 7 located on T6. T8 absent ( Fig. 45 View FIGURES 45–50 ). Epiproct divided, covered with setae. Cercus covered with long setae. Hypoproct large, poorly sclerotized and without setae ( Fig. 46 View FIGURES 45–50 ). ST6 wider than long, with posterior margin widened; with a row of robust setae near posterior margin. ST7 narrowed posteriorly, with anterior margin longer than posterior one, without setae. ST8 represented by a small oval plate, joined with ST7 by a membranous region and covered with setulae ( Fig. 45 View FIGURES 45–50 ). Spermathecae rounded, without grooves or marks ( Fig. 47 View FIGURES 45–50 ).

Remarks. The female terminalia of Peckia ( E.) collusor are similar to those of P. ( E.) epimelia in having ST6 widened posteriorly, ST8 reduced and spiracle 6 located on intersegmentary membrane ( Figs 45 View FIGURES 45–50 , 51 View FIGURES 51–56 ). Peckia ( E.) collusor can be distinguished from P. ( E.) epimelia by the square posterior margin of ST7 and the presence of a membrane between ST7 and ST8 ( Fig. 45 View FIGURES 45–50 ). The female terminalia of P. ( E.) collusor share with P. ( E.) anguilla T5 with an elliptic posterior margin, spiracle 6 located on intersegmentary membrane and spiracle 7 located on T6, but it differs in the shape of ST8 (see Remarks under P. ( E.) anguilla ).

This is one of the most common species in the Brazilian Amazon. It is easily collected in forested environments (d’Almeida 1984; Esposito & Linhares 2002) and is considered to be asynanthropic ( Dias et al. 1984). This species has frequently been collected in the Brazilian Amazon with traps baited with large or small dead animals (fishes, large toads, birds, rats, and pigs) ( Dias et al. 1984; Esposito & Linhares 2002). In addition, P. ( E.) collusor has been reared from a pupa of Brassolis astyra Godart ( Lepidoptera : Nymphalidae ) ( Lopes 1935), feces (d’Almeida 1988), and a dead Hemidactylus mabouia Moreau de Jonnès (Reptilia: Squamata : Gekkonidae ) (personal observation by the second author).
