Peckia (Peckia) hillifera ( Aldrich, 1916)

( Figs 16 View FIGURES 11–20 , 35 View FIGURES 35–38 , 81–86 View FIGURES 81–86 )

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 FIGURES 81–86 ). T6 divided into two halves, yellow, with golden microtrichosity and a row of robust setae near posterior margin ( Fig. 81 View FIGURES 81–86 ). Spiracle 6 located on intersegmentary membrane, spiracle 7 located on T6. T8 absent ( Figs 81, 84 View FIGURES 81–86 ). Epiproct triangular, covered with fine setae. Cercus covered with long and fine setae. Hypoproct triangular, covered with fine setae ( Fig. 82 View FIGURES 81–86 ). 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 FIGURES 81–86 ). Spermathecae globular, with grooves and a small rounded chamber where they receive the spermathecal duct ( Fig. 83 View FIGURES 81–86 ).

Material examined. Brazil. Pará: Bragança, 11.III.2008, leg. R. Santos (6 ♀♀, 3 ♂♂, MPEG); Bragança, Ilha Canelas , 0°47'06"S 46°43'41"W GoogleMaps , 8–13.XI.1995, mangrove, leg. N. Bittencourt (1 ♂, MPEG), same data but 9– 13.VIII.1995 GoogleMaps .

Distribution in Brazil. Pará * (new country record).

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 FIGURES 11–20 ). Females of P. (P.) hillifera have ST8 wider than long and spiracle 6 located on the intersegmentary membrane ( Fig. 81 View FIGURES 81–86 ), while in P. (P.) lutzi ST7 and ST8 are fused and spiracle 6 is located on T6 ( Fig. 87 View FIGURES 87–92 ).

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)].
