Peckia (Peckia) hillifera ( Aldrich, 1916) 

( Figs 16 View Figure , 35 View Figure , 81–86 View Figure )

Description of female terminalia. Posterior margin of T5 triangular, brown with gray microtrichosity and with a row of robust setae near posterior margin ( Figs 84–86 View Figure ). T6 divided into two halves, yellow, with golden microtrichosity and a row of robust setae near posterior margin ( Fig. 81 View Figure ). Spiracle 6 located on intersegmentary membrane, spiracle 7 located on T6. T8 absent ( Figs 81, 84 View Figure ). Epiproct triangular, covered with fine setae. Cercus covered with long and fine setae. Hypoproct triangular, covered with fine setae ( Fig. 82 View Figure ). ST6 square, covered with setae distally and with robust setae near posterior margin. ST7 square, with short, sparsely distributed setulae and a median depression. ST8 reduced, wider than long, with a row of median setulae and two pairs of robust, median setae ( Fig. 81 View Figure ). Spermathecae globular, with grooves and a small rounded chamber where they receive the spermathecal duct ( Fig. 83 View Figure ).

Remarks. Peckia (P.) hillifera  is very similar to P. (P.) lutzi  , since them both have gena and parafacial with gray microtrichosity; males have vesica with a rounded lobe proximally and apex hook-shaped, and females have T5 with a triangular posterior margin. In addition, these species are both associated to coastal environments. However, males of P. (P.) hillifera  differ from those of P. (P.) lutzi  in having juxtal lateral plate square and short (shorter than length of phallic tube), as opposed to pointed and longer than length of phallic tube ( Fig. 16 View Figure ). Females of P. (P.) hillifera  have ST8 wider than long and spiracle 6 located on the intersegmentary membrane ( Fig. 81 View Figure ), while in P. (P.) lutzi  ST7 and ST8 are fused and spiracle 6 is located on T6 ( Fig. 87 View Figure ).

Peckia (P.) hillifera  has been recorded from Bahamas, Cuba, Jamaica, Mexico, Panama, Puerto Rico, Trinidad & Tobago, Venezuela and the USA, and the above records are the first for Brazil. It seems to be restricted to coastal environments of the Brazilian Amazon such as mangrove forests and beaches, where it is relatively common. We reared some specimens from a dead crab [Ucides cordatus (Linnaeus)].
