The genus Peckia Robineau-Desvoidy (Diptera: Sarcophagidae) in the Brazilian Amazon: a new species, new records, descriptions of female terminalia and key to species Author Camargo, Sofia Lins Leal Xavier De Author Carvalho-Filho, Fernando Da Silva Author Esposito, Maria Cristina text Zootaxa 2018 2018-09-20 4483 1 1 35 journal article 29137 10.11646/zootaxa.4483.1.1 ea44347b-d895-4d9a-940f-7f2c8e3c62be 1175-5326 1438483 852D819B-E69C-411B-B086-B3660F38B487 Peckia ( Peckia ) hillifera ( Aldrich, 1916 ) ( Figs 16 , 35 , 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 ). T6 divided into two halves, yellow, with golden microtrichosity and a row of robust setae near posterior margin ( Fig. 81 ). Spiracle 6 located on intersegmentary membrane, spiracle 7 located on T6. T8 absent ( Figs 81, 84 ). Epiproct triangular, covered with fine setae. Cercus covered with long and fine setae. Hypoproct triangular, covered with fine setae ( Fig. 82 ). 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 ). Spermathecae globular, with grooves and a small rounded chamber where they receive the spermathecal duct ( Fig. 83 ). 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 , 8–13.XI.1995 , mangrove, leg. N. Bittencourt ( 1 ♂ , MPEG ), same data but 9– 13.VIII.1995 . 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 ). Females of P. ( P .) hillifera have ST8 wider than long and spiracle 6 located on the intersegmentary membrane ( Fig. 81 ), while in P. ( P .) lutzi ST7 and ST8 are fused and spiracle 6 is located on T6 ( Fig. 87 ). 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)].
