description: Dexosarcophaga lopesi Dodge, 1968 (Figs. 28­35)
Dexosarcophaga lopesi Dodge, 1968: 430. Type­locality: Panama, Barro Colorado Is.; male holotype, SEM. Ref.­ Lopes, 1974c: 520 (holotype examined).
Male – Total length = 8 mm.
Head – Fronto­orbital and parafacial plates gray with intense golden microtomentum, with a row of black setulae along eye margin; frontal vitta dark brown, anteriorly reddish; frons 0.22 X head width; frontal row of 11 bristles; 1 reclinate fronto­orbital bristle, proclinate absent; outer vertical bristle not differentiated from the postocular setae; gena gray with golden microtomentum and black setae; postgena gray with black setae; antenna dark brown, first flagellomere with gray microtomentum, pedicel 0.42 X as long as first flagellomere, arista long plumose on basal 1/2; palpus dark brown.
Thorax – Gray with golden microtomentum, more intensely in postpronotal area. Prosternum bare. Chaetotaxy: acrostichals 3 (weakly differentiated) + 1, dorsocentrals 3 + 4 (two posteriormost longer), intra­alars 2 + 2, supra­alars 2 + 3, postpronotals 3, postalars 2, notopleurals 4, scutellum with 2 strong marginals intercalated by 2 weaker ones, 1 small apical, discals 1, meropleurals 8­9, katepisternals 3 (in a line). Wing hyaline, R1 bare, R4+5 setulose in basal 1/2 to crossvein r­m, costal spine not differentiated, third costal sector without ventral setulae. Legs black, mid femur apically with posteroventral ctenidium (6 spines), mid tibia ventrally with 1 median setae [hind legs lost in the holotype].
Abdomen – Gray with the usual silver tesselation and slightly golden microtomentum laterally; T1+2–3 without median marginal bristles, T4 with a pair of median marginals; ST1­2 with long black hair­like setae.
Terminalia – Syntergosternite 7+8, epandrium and cercus dark brown with sparse gray microtomentum; epandrium with some differentiated dorsal bristles and syntergosternite 7+8 with 3 pairs of marginal bristles (Fig. 28); cercus moderately curved forwards in lateral view (Figs. 28, 29); surstylus clavate with elongated setae in apical half (Fig. 28); gonopod with enlarged base and fine setae along ventral margin (Figs. 30, 31); paramere narrow and slightly curved, with a strong bristle on anterior margin (Figs. 30, 32); phallus and juxta similar to those of D. itaqua (Figs. 30, 33, 34); lateral stylus long with simple base and dentate apex (Figs. 33, 34); median stylus represented by a small, double, rugose lobe between the apices of the lateral styli (Figs. 33, 34); vesica well sclerotized, laterally bearing a pair of small median apophyses, bifurcated at apical portion with convergent and pointed extremities seen in ventral view (Figs. 33, 35).
Female – unknown.
Material examined – Panama. Barro Colorado Is., 1 male (holotype), 20.XI.1956, Rettenmeyers (SEM).
Distribution – NEOTROPICAL – Panama.
Remarks – The phallus of this species closely resembles that of D. transita and D. itaqua, the most noteworthy difference among them is the shape of the vesica, which has small lateral apophyses and convergent apical arms in D. lopesi (Fig. 35). The ST5 of the holotype was not dissected to avoid damaging the type.
