( MZSP)  ; 1 ♂ [dissected], São Paulo, Salesópolis, Estação Biológica de Boraceia , 850 m, 17.x.1963, Rabello & Medeiros leg. ( MZSP)  .

Distribution. Brazil (state of São Paulo).

Diagnosis. Ormiophasia lanei  can be distinguished from other species of Ormiophasia  by fronto-orbital plate with silver pruinosity, clearly contrasting with yellow pruinosity on lower parts of head ( Figs 5FView FIGURE 5, 7FView FIGURE 7); clypeus darker than frontoclypeal membrane; wing hyaline ( Fig. 26FView FIGURE 26); surstylus slender ( Fig. 39CView FIGURE 39), strongly inflected, with posterior outer surface covered with strong setae in upper two-thirds; and apex of male cerci about 1/4 length of cerci, subquadrate in posterior view and 1/3 width of cerci, abruptly constricted. Ormiophasia cruzi  also shares with O. lanei  the shape and color of the head, with the contrast of pruinosity ( Figs 5DView FIGURE 5, 7DView FIGURE 7). However, the former differs from the latter by clypeus of same color as frontoclypeal membrane, wing weakly infuscated around veins M 1 and dm-cu ( Fig. 21GView FIGURE 21), surstylus slender with posterior outer surface covered with weak setae in upper two-thirds ( Fig.View FIGURE 39 39A), and apex of male cerci about 1/3 length of cerci, subquadrate in posterior view and more than 1/2 width of cerci, gradually constricted.

Redescription of male. Body length unavailable (specimens with distorted abdomen); wing length 7.84–8.83 mm (8.29 mm) (n = 4).

Coloration. Head yellow-pruinose, except fronto-orbital plate with silver pruinosity, clearly contrasting with yellow pruinosity on lower parts of head ( Fig. 5FView FIGURE 5). Frontal vitta brown. Ocellar triangle dark brown. Fronto-orbital plate and lunule gray. Antenna yellowish-orange. Parafacial, gena, facial ridge, face and mouthparts brownish-yellow, except clypeus (dark brown). Occiput brown in upper area, becoming brownish-yellow in lower area. Thorax silver-pruinose ( Figs 9FView FIGURE 9, 11FView FIGURE 11). Scutum brown; presutural scutum with three silver-pruinose stripes merged posteriorly after suture. Postpronotal lobe and lateral surface of thorax brownish-yellow. Scutellum and subscutellum brown. Wing hyaline ( Fig. 26FView FIGURE 26). Tegula, basicosta, veins, halter and calypteres brownish-yellow. Legs brownishyellow. Abdomen brownish-yellow at base, becoming brown after tergite three; with silver pruinosity.

Head ( Figs 5FView FIGURE 5, 26A, CView FIGURE 26). Elliptic in frontal view; ratio of head height/head width 0.80. Ocelli 1.5 times the diameter of dorsal ommatidia. Postocellar setae 2. Frontal vitta entirely obliterated. Frontal setae 6–7, convergent, posterior ones shorter and weaker. Arista bare. First flagellomere 2.3 times as long as pedicel. Face 1.2 times wider than facial ridge. Facial ridge 2.6 times wider than parafacial.

Thorax. Basisternum 0.59 times as high as wide (26E); median upper margin rounded, subtriangular. Prosternal tympanal membrane 0.56 times as high as wide. Proepimeral setae 1, upcurved. Anterodorsal corner of anepisternum with 1–2 weak setae, about 1/2 length of first notopleural seta; posterior row with 6–8 setae. Meral setae 4–6. Wing. Three times longer than wide. Basicosta subequal in width to tegula. Base of vein R 4+5 with 2–3 dorsal and 1–5 ventral setae. Section of vein M between crossvein dm-cu and M 1 straight. Legs. Fore femur with row of 10–11 dorsal setae from base to apex and row of 14–15 posteroventral setae from base to apex. Fore tibia with row of 3–4 equally-spaced anterodorsal setae and 1 preapical seta. Mid femur with 2–3 posteroventral basal setae. Hind femur with row of 12–14 anterodorsal setae from base to apex and 3–4 anteroventral basal setae. Hind tibia with 1–2 posterodorsal median setae and 1 preapical seta.

Terminalia ( Fig. 39CView FIGURE 39). Sternite 5 subquadrate; lateral distal lobes not pronounced. Anteroventral epandrial process extending beyond ventral epandrial margin. Dorsal surface of epandrium short, posterior margin slightly higher than anterior margin; lateral ventral margin sharply curved; posterior area articulated to surstylus with open, rounded arch. Surstylus slender, strongly inflected, thicker than apex of cerci in lateral view; posterior outer surface covered with strong setae in upper two-thirds. Cerci: basal margin with distinct median projection; apex about 1/4 length of cerci, subquadrate in posterior view, narrow and tapered in lateral view; apex 1/3 width of cerci in posterior view, abruptly constricted; apex with anterior surface straight, without bend. Postgonite slightly curved, apex tapered in lateral view.

Description of female. Differs from male as follows. Body length 8.11 mm; wing length 9.14 (n = 1). Head ( Figs 7FView FIGURE 7, 26B, DView FIGURE 26). Frontal vitta 1.5 times width of fronto-orbital plate. Fronto-orbital plate with silver pruinosity, clearly contrasting with yellow pruinosity on lower parts of head. Frontal setae 8, from lunule to posterior orbital proclinate seta; second or third anteriormost frontal seta stronger and subequal to subvibrissal setae. First flagellomere 2.5 times as long as pedicel.

Remarks. The female was associated with the males both by being from the same locality and through color of clypeus and body, and head pruinosity. The female of O. lanei  is described for the first time in the present study. Description of the female prothorax was not possible, since there was only one specimen for study and we decided to preserve it intact. As already observed by Tavares (1964: 41), the male terminalia of O. lanei  are very distinct among species of the genus. The subquadrate shape of the cerci apex and the strong inflection of the surstylus are evident. Tavares also assigned to O. lanei  the presence of two pairs of discal scutellar setae ( Tavares 1964: 41), arising at the level of the subapical pair. However, this character is not present in the holotype and in the additional material examined, all of which have only one pair. Regarding its distribution, Ormiophasia lanei  seems to be restricted to the Atlantic Forest of São Paulo state.
