Figs 12–13
Diagnosis
Vein R 1 bare. Male: scutellum without apical setae; vesica narrow at base and expanded at apex in ventral view (Fig. 12E); juxta strongly membranous, smooth and not differentiated from paraphallus (Fig. 12D–E). [Female unknown.]
Etymology
The species epithet ‘ pallida ’ should be treated as a noun in apposition. The name is a Latin adjective ‘ pallida ’ (= Latin), meaning ‘pale’, and alluding to the light apex of the distiphallus.
Material examined
Holotype COLOMBIA • ♂; Caquetá, Chiribiquete National Park, W Campamento; alt. 840 m; 26 Nov. 1992; G. Andrade-C leg.; NHRS [lost].
Paratype COLOMBIA • 1 ♂; same collection data as for holotype; NHRS [lost].
Description
Male (n=2)
Length: 5–6 mm. Differs from D. phoenix sp. nov. as follows:
Frons about0.30 × head width at level of ocellar triangle; 7–9 well-developed frontal setae reaching level of apex of pedicel; gena and genal groove with slightly yellowish-silver pollinosity (Fig. 13A); acrostichals 3 (weakly differentiated) + 1; dorsocentrals 4 (anteriormost shorter) +3 (two minor anterior); intra-alars 2+ 2; meral setae 5–7; abdomen dark brown, with slightly yellowish-silver pollinosity; T4 with 1–2 pairs of lateral marginal setae; row of about 10 marginal setae on T5; marginal setae of ST2–4 slightly differentiated from discal setae; short median incision at posterior margin of ST5 (Fig. 12A); surstylus slightly curved (Fig. 12B); vesica narrow at base and expanded at apex in ventral view (Fig. 12E); juxta arching over acrophallus, strongly membranous, smooth and not clearly differentiated from paraphallus (Fig. 12D–E); median stylus narrow and with apical spines (Fig. 12D–E); lateral stylus equipped with strong spines apically and base curved towards ventral margin of paraphallus (Fig. 12D–E).
Female
Unknown.
Distribution
Colombia (Caquetá).
Remarks
Dexosarcophaga pallida sp. nov. is morphologically similar to Dexosarcophaga currani Dodge, 1968. Males of both species have a stick-like vesica in lateral view (Fig. 12D; Mello-Patiu 2002: figs 53, 56) and a membranous projection from the ventral part of the paraphallus at the level of the acrophallus (Fig. 12D; Mello-Patiu 2002: figs 53, 56). The latter projection may be formed by the paraphallus or be a composite of both the paraphallus and the juxta. These two species can be differentiated by the following features: vesica strongly bifurcated at apex (Fig. 12E) and lateral and median styli approximately ⅓ the length of paraphallus (Fig. 12D–E) in Dexosarcophaga pallida sp. nov., versus vesica slightly bifurcated at apex (Mello-Patiu 2002: fig. 58) and lateral and median styli approximately ½ the length of paraphallus (Mello-Patiu 2002: figs 53, 56–57) in Dexosarcophaga currani.
