Cucullomyia albuquerquei Lopes, 1976b: 750 View in CoL . Type locality: Brazil, Piauí, Valença . Titanogrypa (Cucullomyia) albuquerquei View in CoL ; Pape 1996: 431. (catalogue).

Type-material examined. HOLOTYPE ♂: BRAZIL, Piauí, Valença , 27.iii.1975, Dalcy O. Albuquerque leg. ( MNRJ) [lost].

Diagnosis. Scutellum with a lateral patch of whitish hair-like setulae; vesica with a proximal membranous projection and two distal membranous projections as lateral flaps, sclerotised portion with a pointed ventroapical projection in profile ( Figure 2 View Figure 2 (d,e)); juxta lobular, distally narrower in lateral view ( Figure 2 View Figure 2 (e)); median stylus long, with base broad with internal dentate margins and apical spines ( Figure 2 View Figure 2 (d,e)); lateral styli with base laterally curved, divergent apex and dentate in distal half ( Figure 2 View Figure 2 (d,e)).

Redescription. MALE (n = 1). Body length = 8.0 mm.

Head. Parafacial and fronto-orbital plates with golden pruinosity; fronto-orbital plate with sparse setulae; parafacial plate with row of setulae close to eye and measuring about 0.57 of distance between vibrissae; frons about 0.26 head width at level of ocellar triangle; frontal vitta entirely blackish; rows of frontal setae parallel except anteriormost 2 slightly divergent, 7 well-developed frontal setae reaching level of base of pedicel, the uppermost one shorter than the others; reclinate orbital seta present, proclinate orbital setae absent; outer vertical setae 0.5x inner vertical setae and divergent; ocellar setae as developed as upper frontals; ocellar triangle dark brown; postocellar and paravertical setae present; postocular area with golden pruinosity; gena with golden pruinosity at the top and silver at the bottom, black setae in anterior part and whitish setae close to occiput; postgena with silvery pruinosity and numerous whitish setae; face with silvery pruinosity; facial ridge black with silvery pruinosity, with short setulae in lower half; antenna dark brown, total length 0.90 of distance from insertion to vibrissal level, first flagellomere brown with grey pruinosity and approximately 2.0x longer than pedicel; arista long plumose on basal 2/3; palpus blackish.

Thorax. Black with silvery-grey pruinosity, postpronotum, notopleuron, anepisternum, anepimeron, and katepisternum with slightly yellowish pruinosity; chaetotaxy: acrostichals 0 + 1, pre-sutural dorsocentrals poorly differentiated, except one setae close to the head and one near suture; post-sutural dorsocentrals 4 (anteriormost poorly differentiated, 3 posteriormost well developed with gradual growth), intra-alars 1 + 2, supra-alars 2 + 3, postpronotals 3, notopleurals 4; katepisternals 3; postalar wall setulose; postalar callus with 2 setae; scutellum with a patch of whitish hair-like setulae on lateral margin and reaching ventral part of the scutellum, a pair of basal, lateral and subapical setae (lateral pair shorter), a pair of preapical discal setae, and no apical setae; meral setae 7–9; proepisternum bare; prosternum setulose. Wing. Hyaline, with dark brown veins; tegula dark brown; basicosta yellowish; vein R1 bare; vein R4+5 with setulae dorsally on 1/2 of distance to crossvein r-m; cell r4+5 open at wing margin; third costal sector bare ventrally. Legs. Blackish-brown with silvery pruinosity, pulvilli yellowish-brown; mid femur with a row of 3 − 4 median anterior setae, a row of anteroventral setae, 2 preapical posterior setae, 2 median setae and a ctenidium of 5 − 7 spiniform setae on posteroventral surface; mid tibia with 2 median anterodorsal, 1 basal and 1 median posterior setae, and 1 median posterodorsal seta; hind femur with a row of anterodorsal setae, a row of anterior setae in the proximal half, 1 apical dorsal and 1 apical posterodorsal seta, and rows of anteroventral and posteroventral setae; hind tibia with 1 median anterior seta, 1 basal, 1 median and 1 apical seta in the same position of the anterodorsal and posterodorsal surfaces, and a median anterodorsal seta; hind coxa and trochanter with normal setae.

Abdomen. Dark brown with yellowish grey pruinosity on T1 + 2− T3; T4− T5 reddish brown with yellowish pruinosity; T1 + 2− T4 with lateral marginal setae; T3− T5 with a set of long setae with wavy apex on ventral surface, more numerous on T5; T4 with a pair of median marginal setae; T5 with a complete row of marginal setae (ca. 10); ST2 − 4 rectangular with long setae in distal half; ST5 deeply cleft, short base, long and narrow arms, and longer setae at the arm apex ( Figure 2 View Figure 2 (a)).

Terminalia . Reddish brown; syntergosternite 7 + 8 with yellowish pruinosity and sparse setulae; epandrium with yellowish pruinosity and a pair of developed dorsal setae; surstylus short and clavate, only apical setae, and a small concavity at the apical margin ( Figure 2 View Figure 2 (b)); cercal prongs narrow and parallel in posterior view, with distal end slightly tapered and curved in profile ( Figure 2 View Figure 2 (b)); pregonite long, with curved and spatulate apex ( Figure 2 View Figure 2 (c)); postgonite shorter than the pregonite, with a long median setae and small setulae ( Figure 2 View Figure 2 (c)); basiphallus about 2.5x the paraphallus length, paraphallus with 2 dorsal keels ( Figure 2 View Figure 2 (c,e)); vesica 2x longer than wide in lateral view, sclerotised portion with pointed ventroapical projection, with a proximal membranous projection and two distal membranous projections as lateral flaps ( Figure 2 View Figure 2 (d,e)); juxta lobular, distally narrower in lateral view ( Figure 2 View Figure 2 (e)); median stylus long, with broad base with internal dentate margins and apical spines ( Figure 2 View Figure 2 (d,e)); lateral styli with base laterally curved, divergent apex and dentate in distal half ( Figure 2 View Figure 2 (d,e)).

Female. Unknown.

Distribution (Neotropical). Bahamas, Brazil (Piauí), Cuba.

Comments. Titanogrypa (C.) albuquerquei closely resembles T. (C.) pedunculata and T. (C.) alvarengai in possessing vesica with a proximal membranous projection and without spines in the distal portion ( Figures 1 View Figure 1 (e), 2(e) and 3(e)). This species differs from other congeneric species mainly by having cercus with distal end slightly tapered and curved in profile ( Figure 2 View Figure 2 (b)) and by the unique shape of the membranous basal projection of the vesica when compared to the other species ( Figure 2 View Figure 2 (e)).
