Posterior margin of T5 elliptical, brown, with golden microtrichosity dorsally and gray microtrichosity laterally ( Figs 72–74 ). 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 ). Epiproct triangular, covered with long setae. Cercus covered with long and fine setae. Hypoproct covered with long and fine setae ( Fig. 70 ). 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 ). Spermathecae globular, with parallel grooves restricted to distal half and a small rounded chamber where they receive the spermathecal duct ( Fig. 71 ). Material examined. BRAZIL .

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 , 93 , 99 ). The posterior margin of ST7 of P. ( P. ) pexata has no setae ( Fig. 93 ), which are present on ST 7 in P. ( P. ) chrysostoma ( Fig. 69 ). Peckia ( P. ) uncinata can be distinguished from P. ( P. ) chrysostoma in having posterior margin of ST8 folded ( Fig. 99 ), whereas in P. ( P. ) chrysostoma it is flattened ( Fig. 69 ). 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 ) together with the common, large, habitual specimens with cercus not particularly elongate and only slightly curved ventrally ( Fig. 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 ).
