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.
