Posterior margin of T5 triangular, reddish, with golden microtrichosity and a row of robust, spine-like setae near posterior margin ( Figs 78–80 ). T6 divided into two halves, brown, covered with golden microtrichosity and with grooves on its surface (visible in dry specimens) and robust setae near posterior margin. Spiracles 6 and 7 located on T6. T8 absent ( Figs 75, 78 ). Epiproct triangular, poorly sclerotized, reduced to a patch of setae on the membrane, near the cercus. Cercus covered with fine setae. Hypoproct triangular, covered with long and fine setae ( Fig. 76 ). ST6 elongate, with a pair of robust setae near posterior margin. ST7 shieldshaped, without setae. ST8 wider than long, with lateral margin curved inward and a row of setae near posterior margin ( Fig. 75 ). Spermathecae globular, with grooves and a small rounded chamber where they receive the spermathecal duct ( Fig. 77 ). Material examined. BRAZIL .

( P. ) gulo shares some morphological similarities with those of P. ( P. ) hillifera and P. ( P. ) lutzi , such as T5 with a triangular posterior margin ( Figs 78 , 84 , 90 ). In addition, these three species are found mainly along the coast. Females of P. ( P. ) gulo can be distinguished from females of P. ( P. ) hillifera and P. ( P. ) lutzi by the following features: T5 reddish with spots of silver microtrichosity and a row of thick spine-like setae near posterior margin; ST6 with only one pair of median robust setae; T6 with grooves on its surface ( Figs 75, 78 , 81, 84 ). In P. ( P. ) hillifera and P. ( P. ) lutzi T5 is brownish-black with spots of silver microtrichosity and with a row of long, not spine-like setae near posterior margin; ST6 has more than one pair of robust setae near posterior margin, and T6 lacks grooves on its surface. In addition, P. ( P. ) gulo is a large and robust species, reaching up to 20 mm in length, while P. ( P. ) hillifera and P. ( P. ) lutzi reach about 17 mm . This species was collected only on oceanic beaches and in mangroves in the Brazilian Amazon, with traps baited with rotting organic matter (dead fish and crab, fermented banana and pineapple); it seems to be restricted to estuaries and marshy coastal habitats ( Reeves et al. 2000 ; Buenaventura & Pape 2013 ). Its larvae appear to breed only in dead crabs ( Reeves et al. 2000 ; Méndez & Pape 2002 ), which is consistent with some specimens obtained from a dead crab [ Ucides cordatus (Linnaeus)] collected by Dr. Rita Santos (College Bragança, Universidade Federal do Pará ) in mangroves of the Brazilian Amazon.
