(figures 13A–H, 14A–F)

Pityocera (Pseudelaphella) patellicornis, Henriques & Gorayeb, 1993: 5 ; Henriques, 1997: 62.

Type locality. Brazil, Pará, Conceição do Araguaia.

Diagnosis. size varying from 9.3 to 13.8 mm; frons parallel sides; gena and parafacial pruinose, face and clypeus smooth and shiny light brown; beard white; antennal flagellum orange, with five free flagellomeres darkened; femora yellow, tibiae and tarsi more darkened.

Description, Holotype ♀. based on a specimen from Conceição do Araguaia, Pará. Body length 12.8 mm (fig. 13A); wing length 11.2 mm; wing width 3.7 mm.

Head (fig. 13B): eyes without color pattern when dry, densely pilose. Occiput with yellowish white hair. Frons parallel, D.I. 1.0, F.I. 3.2; with yellowish brown pruinosity and black pilosity. Subcallus glabrous, with pruinosity identical to frons. Face smooth and shiny (translucent yellow) with some sparse black hairs; clypeus smooth and shiny, light brown; parafacial and gena with whitish pruinosity and white beard. Antenna (fig. 13C) scape and pedicel with yellowish brown pruinosity and dark hairs; flagellum orange, without pruinosity; eight flagellomeres, flagellomeres 1–3 fused, 4–8 free (darker); first flagellomere (although hard to see due to the almost complete fusion with the second) higher than long, with tuft of dorsal hairs; apical flagellomere with black hair. Palpus with first segment tubular and short, less than half of the second; second segment with basal and median enlargements, occupying more than half of the length, hairs only on external margins; central area yellowish and bare remainder narrow and completely pilose; proboscis slender and very long, over twice the length of the head.

Thorax: scutum dark brown, with black hairs and three longitudinal bands of brown pruinosity; post-pronotal lobe, notopleura, post-alar callus and scutellum apex with brown pruinosity. Notopleura with tuft of black hairs (dorso-lateral view). Pleura with dark integument covered by greyish brown pruinosity and predominantly white hairs. Legs slender; coxae with pruinosity and pilosity similar to pleura; trochanters and femora yellow with sparse black and white pilosity; tibiae and tarsi yellow, darker due to black pilosity in dorsal view. Wing infuscated; r5 cell closed with petiole very long; appendix of R4 vein very short; venation dark brown.

Abdomen: tergites 1–2 bright yellow with dark spot in the middle; tergites 3–7 dark brown with bright posterior transverse bands; pilosity predominantly black, with some white hairs.

Terminalia (paratype). Tergites IX and X, cercus and hypoproct as in figure (fig. 13F). Tergite IX fused, a little narrower than tergite X. Tergite X rectangular, divided into two pieces. Cercus with margins rounded and apex slightly acuminate. Hypoproct rounded, reaching the first third of the cercus length. Hypogynium + hypogynial valve (fig. 13G). Hypogynium subtriangular with lateral margins straight from the second basal third to the apex, and slightly rounded on the first third; apex with a v-shaped slit reaching the hypogynial valve. Genital fork (fig. 13H) with arms slender, but with great distal expansions heavily sclerotized; anterior margin with sharp median indentation; lateral extremities pointed; spermathecal ducts long and little sclerotized; spermatheca (fig. 13H) heavily pigmented, thin, with apex narrowed.

Paratypes variation. Body length 9.3–13.8 mm; wing length 9.0– 11.8 mm; wing width 2.9–3.9 mm; F.I. 2.7–3.2; D.I. 1.0;

Male (figs. 14A–F): similar to the female in terms of pruinosity and pilosity patterns. Differs in the following characters: head holoptic (fig. 14A); ommatidia equally sized; first flagellomere more elongated (fig. 14B); palpus porrect, with first segment a little shorter than the second; second segment of the palpus without distal narrowing, with central area bare.

Terminalia. (figs. 14C–F). Epandrium, cercus and hypoproct as in figure 14E–F. Epandrium fused, with lateral margins rounded slightly excavated in the apex (dorsal view). Cercus subrectangular. Hypoproct elongated and acuminate, exceeding the apex of the cercus. Hypandrium + gonocoxite, gonostylus and aedeagus as in figure 14C–D. Hypandrium + gonocoxite robust, with anterior margin straight; gonocoxite hollow (dorsal view) developed reaching approximately half of its length. Gonostylus elongate with slightly proximal-posterior indentation and apex pointed (beak shaped); aedeagus slender without anterior enlargement; slightly more robust than the gonocoxal apodemes; length subequal to the gonocoxal apodemes.

Distribution. Brazil (Pará, Maranhão, Ceará, Tocantins, Rondônia, Mato Grosso, Goiás, Mato Grosso do Sul), Bolivia (Santa Cruz).

Etymology. “ rhinos ” = nose and “ lissos ” = smooth, both from Greek.

Discussion. similar instance to P. pernaquila sp. nov. here described as a new species, but formerly treated as P. patellicornis in Henriques & Gorayeb (1993) and Henriques (1997). Mistake associated with a specimen from Bolivia, deposited at MPEG, which was identified by Fairchild in 1979 as P. patellicornis (figs. 13D–E). This specimen has face completely smooth and shiny, clearly differing from the Lectotype of P. patellicornis , which has the face completely pruinose.
