An unknown Calliphora-like tachinid fly. The most interesting character seems to be the males have the postabdomen large, exposed and forming a verticle declivity. Males of tribe Parerigonini have the same postabdomen but following Crosskey (1973) I don't get to genus satisfactorily (Zita being the closest). Body length around 11.5mm.
Some notes from a male specimen:
HEAD: palpi thin, weakly broadened apically, with short black setae apically, longer black setae along length; eyes practically bare (only sparse minute setae detectable under high magnification), upper occiput with yellow hairing beyond the postocular row of black setulae.
THORAX: propleuron haired; 4 strong sternopleurals, 3+1; three propleural seta, none distinctly differentiated; three prostigmatic setae, none distinctly differentiated; no distinctly differentiated pteropleural seta; tuft of setulae (infrasquamal hairs) present on top of mediotergite; prosternum without distinct large setae; barette with only a group of 4 weak setulae anteriorly at the swelling immidiately above the hypopleuron; both thoracic spiracles golden orange.
WINGS: node of R4+5 with three bristles above and below; second costal sector haired below, though hairing more restricted to a single line of setae; cell r5 open; lower calypter without any noticeable fine erect hairs, broad apically, close to scutellum but not against.
ABDOMEN: sternites visible; T1+2 excavate to margin; T1+2 with lateral marginals; T3 with a pair of medial discals, a pair of medial marginals, and a short series of lateral marginals; T4-T5 with a pair of medial discals, marginals along the length; postabdomen large, exposed and forming a verticle declivity.
LEGS: mid tibiae with ventral bristle set around ¾ along length; hind tibiae lack preapical posterodorsal bristles.
