Parasycorax satchelli (Barretto)

( Figures 1–8 )

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

Material examined. BRAZIL, Espirito Santo, Cariacica municipality, Reserva Biológica Duas Bocas, 20º28’S, 40º46’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 ); antenna with 13 flagellomeres, with the terminal flagellomere having a small apiculus ( Fig. 2 ); 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 ). Wing ( Fig. 4 ): Sc incomplete not reaching the wing margin; distal end of Sc slightly sclerotized; sc-r short; h lost; R2+3, R4, R5 and M1 not reaching the wing margin; Rs not reaching R1; R5 incomplete at base; r-m absent; CuA1 incomplete at base, not reaching CuA2; m-cu present. Gonocoxite slightly longer than wide; base of the gonocoxite having a lateral group of short sensorial setae ( Fig. 5 ). 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 ). Aedeagus bifid ( Figs 7, 8 ), with the distal end directed upward ( Fig. 8 ). Aedeagal apodeme almost with the same length as the aedeagus ( Fig. 7 ). Paramere plate-like, without long bristles ( Fig. 7 ).

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.
