Peckia (Peckia) chrysostoma ( Wiedemann, 1830)
( Figs 20 View FIGURES 11–20 , 37–38 View FIGURES 35–38 , 69–74 View FIGURES 69–74 )
Description of female terminalia. Posterior margin of T5 elliptical, brown, with golden microtrichosity dorsally and gray microtrichosity laterally ( Figs 72–74 View FIGURES 69–74 ). T6 divided into two halves, brown, with golden microtrichosity and a row of setae near posterior margin. Spiracles 6 and 7 located on T6. T8 absent ( Fig. 69 View FIGURES 69–74 ). Epiproct triangular, covered with long setae. Cercus covered with long and fine setae. Hypoproct covered with long and fine setae ( Fig. 70 View FIGURES 69–74 ). ST6 square, covered with robust setae near posterior margin. ST7 rectangular, with setae restricted to posterolateral margin. ST8 wider than long, with short setulae and a pair of robust lateral setae near posterior margin ( Fig. 69 View FIGURES 69–74 ). Spermathecae globular, with parallel grooves restricted to distal half and a small rounded chamber where they receive the spermathecal duct ( Fig. 71 View FIGURES 69–74 ).

Remarks. The female terminalia of P. (P.) chrysostoma , P. (P.) pexata and P. (P.) uncinata share spiracles 6 and 7 both situated on T6 ( Figs 69 View FIGURES 69–74 , 93 View FIGURES 93–98 , 99 View FIGURES 99–104 ). The posterior margin of ST7 of P. (P.) pexata has no setae ( Fig. 93 View FIGURES 93–98 ), which are present on ST 7 in P. (P.) chrysostoma ( Fig. 69 View FIGURES 69–74 ). Peckia (P.) uncinata can be distinguished from P. (P.) chrysostoma in having posterior margin of ST8 folded ( Fig. 99 View FIGURES 99–104 ), whereas in P. (P.) chrysostoma it is flattened ( Fig. 69 View FIGURES 69–74 ).
The shape of the male cercus of this species is highly variable, as previously mentioned by Lopes (1976), and some specimens within this range of variation were described as two new species by Lehrer (2006). In the Brazilian Amazon, we collected some small specimens (6.5–8.0 mm) with an elongate and sinuous, ventrally-curved cercus ( Fig. 20 View FIGURES 11–20 ) together with the common, large, habitual specimens with cercus not particularly elongate and only slightly curved ventrally ( Fig. 38 View FIGURES 35–38 ).
Peckia (P.) chrysostoma is one of the most common and widely distributed species in the genus, occurring in cities, secondary forests, and pristine forests of the Brazilian Amazon ( Sousa et al. 2011). One of us (FSCF) collected this species on the stinkhorn fungus (Phallus sp.; Phallales: Basidiomycota) and on flowers of Casearia sp. ( Salicaceae ).
