Porphyrochroa neblina View in CoL sp. nov.
(Figs. 11a–m; 19a; 20)
Diagnosis: P. neblina sp. nov. differs from all other studied species due to the presence of two anteroventral spines on the base of the midleg. Is closely related to P. distinctipennis due to the ventral projection on the base of the circus, but differs due to the absence of hypandrial setae.
Description. Male: body length 3.3 mm; wing length 3.5 mm.
FIGURE 11. Porphyrochroa neblina sp. nov., holotype male: a, Tergites 6–8, dorsal view; b, Sternites 6–8, dorsal view; c, Terminalia, lateral view; d, Hypandrium, phallus, cercus and subepandrial sclerite, lateral view; e, Epandrium, lateral view; f, Hypandrium, posterior view; g, Ejaculatory apodeme, anterior view; h, Cercus, dorsal view; i, Subepandrial sclerite, ventral view. Female: j, distal abdominal segments, lateral view; k, abdominal sternites, dorsal view; l, abdominal tergites, dorsal view; m, genital fork, dorsal view. Abbreviation: a cerc, anterior cercus; cerc, cercus; ej apod, ejaculatory apodeme; goncx apod, gonocoxal apodeme; hypd, hypandrium; p cerc, posterior cercus; ph, phallus; sbepand scl, subepandrial sclerite; ST, sternite; T, tergite; vpc, ventral projection of cercus.
Frons and face shiny brown. Frons slightly narrower than width of anterior ocellus, sides subparallel, with five setae. Face slightly longer than frons, length about twice width of frons. Proboscis light-yellow, length equal to height of head. Palpus brown, with one small and almost apical seta. Ocellar tubercule with vitreous light-yellow ocellus; two weak proclinate ocellar setae; two proclinate and convergent postocellar setae. Antenna with scape, pedicel and flagellum brown; scape and pedicel medially verticillate; flagellum about four times longer than scape and pedicel combined. Postcranium shiny brown, with distinct brown setae and gray pruinescence; one pair of parallel vertical setae; postocellar setae distinct, light-brown, arranged in complete single serie. Gena and postgena with setae brown to black and sparse gray pruinescence. Thorax shiny brown, with gray pruinescence conspicuous. Thoracic setae: 3 slender ktg; 4 sctl, larger internal pair; aprn broken; 4 prepm; 1 pprn; 3 acr; 4 dc; 1 spal presut; spal psut broken; 3 ntpl; 2 pal. Legs with coxae, trochanters and basal fifth of femora yellow, remaining segments brown. Hind tibia with four pairs of long dorsal setae; posterior basal tarsomere with two long dorsal setae; mid basal tarsomere with two anteroventral spine in basal region. All legs with short distinct setae. Wing hyaline, elongate and narrow, with conspicuous pterostigma; anal lobe slightly wide ( Fig. 19 View FIGURE 19 a). Halter brown. Abdomen shiny dark-brown, with metallic green luster in diverse light incidence angles. Sternites shiny dark-brown. Tergite 7 with pair of posteroventral protuberances (Fig. 11a); tergite 8 smaller than former ones (Fig. 11a); sternites 6, 7 and 8 with proportional sizes in dorsal view; sternite 8 wider than long (Fig. 11b) and sternites 6 and 7 inclined in lateral view (Fig. 11c). Terminalia: hypandrium without setae (Fig. 11d); in posterior view, with three superior projections (Fig. 11f). Epandrium semirectangular with long setae in the dorsal region (Fig. 11e). Cercus elongate and wide in lateral view (Fig. 11d); in dorsal view with rounded apex, internal ventral projection and spiniform setae internally (Fig. 11h); ejaculatory apodeme with three projections in anterior view (Fig. 11g); subepandrial sclerite elongate (Fig. 11i).
Paratype (female): Similar to male in all respects except red proboscis, ocellus and eyes; dark-brown antenna. Sternites and tergites as in Figures 11k; l. Fork genital as in Figure 11m. Cercus folded outside (Fig. 12j–l).
Distribution: BRAZIL (Amazonas).
