Santis, Marcelo Domingos de & Nihei, Silvio Shigueo, 2016, Review of the New World genus Cholomyia (Diptera, Tachinidae), with a new species from Costa Rica, Revista Brasileira de Entomologia 60 (3), pp. 217-226 : 224-225

C. zumbadoi sp. nov.

( Figs. 37–44 )

Diagnosis. C. zumbadoi differs from C. acromion and C. filipes , and it resembles more with C. inaequipes , by having the mid leg approximately twice the length of the other legs, two katepisternal setae, postpronotum with two basal setae and abdominal syntergite I + II entirely yellow. Moreover, C. zumbadoi differs from C. inaequipes by having the anepisternum with 4–5 upward setae on anterodorsal corner, surstylus without concavity and curved externally in profile view, ejaculatory apodeme narrow at base and very wide at apex (about twice the basal width), about 1.3× longer than cerci and pregonites with basal portion narrowed.

Description

Male ( Figs. 37–40 )

Body length: 8.3 mm in average (8.0– 8.8 mm; n = 4). Wing length: 8.4 mm in average (8.0– 8.5 mm; n = 4).

Colouration. Genal groove dark yellow. Antenna yellow. Proboscis and palpus pale yellow. Prescutum usually with yellow pruinosity. Thorax dark brown. Fore leg with yellow femur, mid and hind femur yellow (except for blackish posterior margin about distal ¼), and all legs with tibia and tarsus black. Abdomen yellow, but light brown thin band on posterior margins on tergite III (about ¼) and tergite IV with black posterior margin, about distal 2 ⁄ 3 of width.

Head. ( Figs.39, 40 ) Frontal vitta narrow.Gena, when seen in profile, about 0.4–0.5 times as height as eye. Gena and parafacial with thin pale pruinosity.

Thorax. ( Figs. 37, 38 ) Postpronotal lobe with 2 basal setae. Supra-alar setae 1 + 2. Postalar setae 1 to 2. Scutellum with one basal, one discal (weak or absent), one subapical and one apical (generally decussate) pairs of setae. Anepisternum setae with 5–6 of strong setae and with 4–5 developed upward setae on anterodorsal corner. Katepisternal setae 2 (anterior and posterior).

Wing. R 4+5 setulose dorsally from Rs node until half of distance to r-m crossvein and R1 fully setulose dorsally (scarce in the median region). Rs node with 5 setulae ventrally.

Legs. ( Fig. 38 ) Fore femur with row of PD and PV setae, fore tibia with 2 PD and 1 PV setae on median third, and 1 D and 1 PV preapical setae. Mid leg very elongate, twice longer than other legs, 20.5 mm in average (20.3–20.8 mm; n = 4), mid femur with 4 supramedian AD setae, 1 preapical PV seta; mid tibia with 2 supramedian AD setae, and 1 D, 1 V and 1 P preapical setae. Hind femur with a row of AV (usually) and AD setae, 1 submedian D seta, and 1 preapical P seta; hind tibia with 1 supramedian AD seta, 1 median AD seta, 1 median AV seta, 1 submedian D seta and 1 DV preapical seta.

Abdomen. ( Figs. 37, 38 ) Syntergite I + II with 2 pairs of lateral marginal setae. Tergite III (rarely) with 1 lateral marginal pair of seta. Tergites IV and V with 2 pairs of lateral marginal setae and 1 pair of median marginal setae.

Male terminalia. ( Figs. 41–44 ) Cerci tapered at apex, touching each other or not, in posterior view ( Fig. 44 ), narrowed tip without curvature in profile ( Fig. 43 ). Surstylus without narrowing near the apex, in posterior view ( Fig. 44 ), slightly curved posteriorly, with absence of concavity, in profile ( Fig. 43 ). Base of pregonite sub-triangular with basal portion narrowed, postgonite rod-shaped with strong setae, beginning at the base of distiphallus ( Fig. 42 ). Ejaculatory apodeme very wide at apex, with conspicuously supersized, about 1.3× length of cerci ( Fig. 41 ).

Female. Unknown.
