Stylogaster latifrons

description: Stylogaster latifrons sp. n.   Figs 163–172  
 Etymology: From the Latin latus (broad) and frons (forehead), a significant character of the new species being the broad frons with vertical setae close to the eye margin.   
 Diagnosis: Stylogaster latifrons sp. n. has a broad frons, the distance of the vertical seta to lateral ocellus being greater than the distance between the lateral ocelli (Fig. 166); occiput with only 3 long white setulae ventrally, and mouth opening with 5 or 6 short black setulae. The terminalia are diagnostic, with some long setulae distally on cercus (Fig. 171).   
Description (based on holotype):  
 Male.   
 Overall length ca 4.7 mm.   
 Head: 1.3 mm high. Eye red-brown, with a few scattered inconspicuous ommatrichia. Facets on inner side slightly enlarged. Ocelli pale yellow. Ocellar tubercle brown, with 1 pair of ocellar setae. Ocellar triangle occupies virtually entire frons, reaching as far as antennae (Fig. 166). Ocellar triangle brown. Frons brown lateral to ocellar triangle, with 2 discernible small fronto­orbital setae.Antenna yellow, basal flagellomere brown distally and dorsally. Arista brown, 3 segments evident. Arista situated dorsally at apex of basal flagellomere (Fig. 165). Scapus with few black setulae dorsally. Pedicellus with black setulae. Shape of antenna as illustrated in Fig. 165. One vertical seta positioned close to eye (Fig. 166). Face pale yellow with silver pruinosity. Occiput blackish brown, distinctly silver pruinose; with row of regularly-arranged small white setulae, and three long white setulae ventrally. Five or six short, black setulae on mouth opening. Proboscis pale yellow basally, becoming black distally, except for yellow-brown distal division of labellum. Labrum ca 1.9 mm, labellum approximately same length.   
 Thorax: Yellow-white; mesoscutum (with exception of postpronotum and postalar calli), scutellum and triangular area of mediotergite brown. All setae black. Two notopleural setae, 1 supra-alar seta (1 damaged), 2 postalar setae (1 damaged), 1 praescutellar dorsocentral seta (1 damaged), 1 apical scutellar seta (2 damaged), 1 seta on anepimeron (2 damaged) and 1 seta above fore coxa on propleuron (1 damaged). A few black setulae on anepimeron. Black semi-adpressed setulae on mesoscutum partly arranged in rows and forming medial row of denser setulae.   
 Wing: Length 4.6 mm. Generally clothed in microtrichia, but bm and partly cup without microtrichia. Hind margin of wing with black or brown setulae. Venation as in Fig. 167. Haltere uniformly pale yellow, with areas of sensillae at base. Fore and mid leg pale yellow-white. Hind leg brown with pale area medially on hind femur and hind tibia with yellow-white subapical area.   
 Legs: Mainly with black or brown setulae, only fore and mid tibiae with pale yellow setulae. All setae black. Fore coxa with 2 distinct setae and several black setulae. Mid coxa with 1 black seta and additional black setulae. Hind coxa with 1 lateral black seta and with strong black setulae distally on anterior surface. Hind trochanter without teeth or dense setulae. Mid femur with a row of regularly-arranged, black setulae posteriorly in basal half. Hind tibia with 4 short, black spines on anterior surface. Claws dark brown basally, distally black. Pulvilli brown. Empodia short, brown.   
 Abdomen: Mainly pale brown, tergite 1 dark brown, tergites 2–4 with dark brown hind margin, tergite 6 dark brown laterally (Fig. 164). Tergites with semi­adpressed black setulae. Tergite 1 with long black setulae laterally, tergite 2 with 3 black lateral setae on either side of anterior margin. Terminalia as illustrated in Figs 168–172. Cercus triangular (Fig. 171). Dorsal margin concave. Some conspicuous long setulae distally (Fig. 171). Cercus with small inconspicuous lappet ventrally. No black setae. Surstylus without black teeth. No setulae on inner surface. Phallus sheath as illustrated in Fig. 170. Black setae basally and slightly darkened apex conspicuous.   
 Female. Unknown.
