Head and trunk yellow; antenna black; wings hyaline, pterostigma and fore wing vein Rs+2r black; propodeum, legs and metasoma brown. Gena in lateral view trapezoidal (Fig. 6 C). Epicnemial carina absent on mesopleuron. Weakly inflated scutellum (Fig. 6 D), in lateral view evenly rounded. Fore wing vein Rs+2r curved and thickened at its basal quarter (Fig. 6 E–F); marginal cell with a conspicuous glabrous proximal region (Fig. 6 F); vein cu-a reaching M+Cu basad of Rs&M (Fig. 6 F). Description (Holotype). Female. Mandible slender, apically strongly compressed and twisted about 90°; outer tooth acute, as long as inner one; outer mandibular surface with a shallow concavity crossing mandible at basal boundary of compressed area. Labrum 0.25x as long as wide basally. Malar space 0.25x as long as basal mandibular width. Clypeus weakly convex in lateral view, with margin truncate, about 1.5x as broad as long. Face alutaceous with setae sparcer centrally. Gena in lateral view trapezoidal (Fig. 6 C). Lateral ocellus contiguous with eye. FI = 52%. ECI = 0.96. Occipital carina absent. Antenna with 66 flagellomeres; twentieth flagellomere 2x as long as broad. Mesoscutum polished, densely pilose, evenly rounded in lateral view; without notaulus. Mesopleuron polished, pilose; alutaceous below and smooth above mesopleural furrow, with a conspicuous glabrous region anterior to speculum. Epicnemial carina interrupted centrally on sternum; absent on pleuron. Scutellum smooth and shiny; 1.1x as long as anterior width; weakly inflated; without lateral carina; in lateral view evenly rounded. Metapleuron weakly convex, alutaceous. Submetapleural carina weakly broadened anteriorly. Posterior transverse carina of mesosternum reduced to lateral vestiges. Propodeum densely pilose, abruptly declivous in lateral view; anterior transverse carina complete, not touching lateral longitudinal carina; posterior transverse carina complete; median longitudinal carina complete, thin apically; lateromedian longitudinal carina absent; anterior area longitudinally rugose; posterior area weakly rugulose; lateral longitudinal carina complete. Fore wing length 15.4 mm; AI = 0.67; CI = 0.29; ICI = 0.99; SDI = 0.87; SRI = 0.45; vein cu-a reaching M+Cu basad of Rs&M (Fig. 6 F). Discosubmarginal cell (Fig. 6 F) with a glabrous area anteriorly, from pterostigma to half length of vein Rs+2r which is abruptly curved and thickened on its basal quarter; 1m-cu abruptly curved at middle, straight at both basal and apical halves, without ramellus. Marginal cell (Fig. 6 F) with a conspicuous glabrous area basally, reaching two thirds of Rs+2r length. Left hind wing R1 with four hamuli, right one with three hamuli; Rs with basal half of first abscissa weakly bowed, distal half and second abscissa straight; BCI = 0.57; basal abscissa of Cu1 about 2.3x as long as cu-a. Mid leg with equal sized tibial spurs. On hind leg, coxa in lateral view 2x as long as maximum wide, at middle; fourth tarsomere 3.6x as long as broad apically; claws long, with pectinae with uniform height towards apex. Metasoma long and slender. Tergite 2 in lateral view 4x as long as posterior width; laterotergite pendant; thyridium oval, separated from anterior margin by 6.6x its length. Ovipositor straight and slender (Fig. 6 G); subapical notch with two steps-like sculpture on its apical rim inner surface; with 4 teeth on lower valve apex. Head and trunk yellow. Propodeum, legs and metasoma brown. Antenna black. Mesoscutum with three broad black longitudinal fasciae. Apical half of tergite 3 and posterior tergites infuscate. Wings slightly infumate, pterostigma and fore wing vein Rs+2r black. Males. Similar to females. Genitalia with gonostipes fused dorso-basally (Fig. 10 G); gonocardo fused to gonostipes without ventral apophysis (Fig. 10 E, G); gonostipes with shallow dorsal longitudinal sulcus, without sculpture (Fig. 10 F–G); apical indentation of gonostipes ellipsoid; gonostipital arm acuminate; gonolacinia with short spines concentrated in a single region; distivolsella spatulate. Aedeagus stem (Fig. 10 H) is abruptly thickened at its basal third; in lateral view, dorsal surface is straight. Aedeagus apical process forms a right angle with the stem dorsal line in lateral view; ventrally, it is convex. Variation. Ranges for some features varying among the observed specimens are: FI = 52–57%; ECI = 0.69– 0.99; number of flagellomeres = 59–66; fore wing length = 12–15.4mm; AI = 0.46–0.81; CI = 0.26–0.62; ICI = 0.94–1.14; SDI = 0.8–0.94; SRI = 0.44–0.5; BCI = 0. 45–0.6; number of hamuli on hind wing R1 vein = 3–4; basal abscissa of hind wing Cu1 vein 2–3.6x as long as cu-a. The male collected in São Paulo in 1961 has the propodeal lateromedian longitudinal carina present between the posterior transverse carina and the propodeum apex. Comments. The apex of metasoma is missing in one of the specimens collected in São Paulo, which prevents identification of its sex. The geographical coordinates of the type locality were obtained from the work of Marinoni and Dutra (1991). Etymology. This species is named after Leotacílio da Fonseca, in recognition of his valuable contribution to the study of the insects of Estação Ambiental Peti, Minas Gerais. Distribution. Stauropoctonus leotacilioi sp. n. is described from Brazil: Minas Gerais, São Paulo and Paraná states. Material examined. Holotype (♀). Brasil, Paraná, São José dos Pinhais. (BR277-km54) 10.iv.1985, C.I.I.F. (Luminosa). [DZUP] Holotype condition. Tarsomeres 2–5 of right middle leg and tip of left antenna are missing. Apart from that it is in good condition.
