Parasycorax satchelli (Barretto)  

( Figures 1–8 View FIGURES 1 – 8 )

Sycorax satchelli Barretto, 1956: 73   –75; Figs. 9 View FIGURES 9 – 16 –18.

Material examined. BRAZIL, Espirito Santo, Cariacica municipality, Reserva Biológica Duas Bocas, 20 º 28 ’S, 40 º 46 ’W, 1.XI. 2007, Santos, C.B. col., two males (MZUEFS); Cariacica municipality, Alto Alegre, 02.V. 2008, Santos, C.B. col., six males (MZUEFS); Viana municipality, Formate, 11.VIII. 2008, Santos, C.B. col., 1 male (MZUEFS).

Diagnosis. Male. Scape cylindrical and the same length as the pedicel ( Fig. 1 View FIGURES 1 – 8 ); antenna with 13 flagellomeres, with the terminal flagellomere having a small apiculus ( Fig. 2 View FIGURES 1 – 8 ); ascoids present on all flagellomeres, sinuous, 2.0 times as long as flagellomere. Palpus with four segments, the last one being approximately 2.0 times as long as third segment ( Fig. 3 View FIGURES 1 – 8 ). Wing ( Fig. 4 View FIGURES 1 – 8 ): Sc incomplete not reaching the wing margin; distal end of Sc slightly sclerotized; sc-r short; h lost; R 2 + 3, R 4, R 5 and M 1 not reaching the wing margin; Rs not reaching R 1; R 5 incomplete at base; r-m absent; CuA 1 incomplete at base, not reaching CuA 2; m-cu present. Gonocoxite slightly longer than wide; base of the gonocoxite having a lateral group of short sensorial setae ( Fig. 5 View FIGURES 1 – 8 ). Gonostylus with three long spines, one being apical and the other two articulated along their mid-ventral surfaces; presence of a group of long apical bristles; base of the gonostylus having a dorsal group of short sensorial setae ( Fig. 7 View FIGURES 1 – 8 ). Aedeagus bifid ( Figs 7, 8 View FIGURES 1 – 8 ), with the distal end directed upward ( Fig. 8 View FIGURES 1 – 8 ). Aedeagal apodeme almost with the same length as the aedeagus ( Fig. 7 View FIGURES 1 – 8 ). Paramere plate-like, without long bristles ( Fig. 7 View FIGURES 1 – 8 ).

Female. Similar to male except in relation to the following characters: ascoids shorter than in males, 0.60–0.75 times as long as flagellomere; spermatheca in pairs, spherical, covered with small bristles.

Comments. The type specimens of P. satchelli   (holotype male, three paratype males, and five paratype females) were not found in the Departamento de Parasitologia of the Universidade de São Paulo, Ribeirão Preto, Brazil where they had been deposited by Professor Mauro Barretto. The Mauro Barretto collection was deactivated at the Departamento de Parasitologia – USP, Ribeirão Preto and no longer exists. Other type specimens of Barretto’s species of Trichomyia   and Maruina   (which had been deposited in the same Department of Parasitology) were localized in the Departamento de Ciências Farmacêuticas da Universidade de São Paulo, Ribeirão Preto; however, the Bruchomyiinae   and Sycoracinae   described by him were not found there.

Distribution. São Paulo (Horto Florestal da Cantareira, near to the city of São Paulo; Mogi das Cruzes), Espírito Santo (Cariacica municipality near the capital Vitória – a new record).

Habitat. All Brazilian localities where P. satchelli   was recorded are in the Atlantic Rain Forest Biome. The specimens from Espírito Santo were collected in the forest with a CDC light trap placed 15m above ground level.
