( Figs 23–24 ) Description. Length. Male: 4.1–4.2mm .. Coloration. General color stramineous with brown or orange-red marks ( Fig. 23 A–C). Crown with pair of small apical submedial spots, four spots between anterior eye angles and two spots on posterior margin; pronotum, mesonotum and scutellum symmetrically marked with brown or orange-red ( Fig. 23A, B ). Frontoclypeus brown with sordid white arcs reaching only part way across ( Fig. 23D, E ). Forewing translucent with fuscous tint and white veins ( Fig. 23 A–C). Femora and tibiae with dark brown marks ( Fig. 23C ). Abdominal sternites variably infused with dark brown. FIGURE 22. Stirellus sagittarius A, B: male pygofer lobe, lateral view; C: male pygofer and segments X and XI, dorsal view; D: valve, subgenital plates and styles, ventral view; E, F: style, dorsal view; G: connective, dorsal view; H: aedeagus, dorsal view; I: aedeagus, lateral view; J: connective and aedeagus, lateral view. FIGURE 23. Stirellus lesioensis sp. nov. A, B: habitus, dorsal view; C: habitus, lateral view; D, E: face. A, D: holotype, male; B, C, E: paratype, male. Morphology. Head nearly subequal in width to pronotum, subconical, anterior margin rounded to face, angled in dorsal and lateral view ( Fig. 23 A–C). Crown with anterior margin forming right angle in dorsal view, slightly longer than width between eyes ( Fig. 23A, B ). Anteclypeus parallel-sided, extending slightly beyond normal curve of genae ( Fig. 23D, E ). Pronotum median length slightly longer than median length of crown. Mesonotum and scutellum together nearly as long as pronotum ( Fig. 23A, B ). Forewing macropterous, with few to many supernumerary crossveins ( Fig. 23 A–C). Male genitalia. Pygofer side long, with few macrosetae dorsally, dorsal margin slightly concave distally, posterior margin nearly truncate ( Fig. 24A ). Subgenital plate slightly concave laterally, macrosetae uniseriate laterally ( Fig. 24C ). Style apophysis digitate, laterallylaterally curved, preapicalpreapical lobelobe poorlypoorly developed, roundedrounded ( Fig. 24D ). Con-Con-Connective Y-shaped, stem broad and shorter than arms ( Fig. 24E ). Aedeagal shaft bent dorsad near base, long, very slender, sinuate in lateral view, apex abruptly tapered to point in dorsal view ( Fig. 24 F–H). Material examined. Holotype : Ƌ, REP OF CONGO Dept Pool , Abio Lesio-Louna Pk , 03° 06′ 020" S 15° 31′ 440" E , 330m , MT, 29 viii 2008 , coll. Braet & Sharkey ( INHS ) . Paratype : 1Ƌ, same data as holotype ( INHS ) . Etymology. The species epithet is based on the type locality. Distribution. Republic of Congo . Remarks. This species can be distinguished from other species of Stirellus by the distinctive color pattern of the crown ( Fig. 23A, B ), presence of supernumerary crossveins on the forewing, and the relatively long, apically truncate male pygofer ( Fig. 24A, B ). The Australian species S. hanuala also has supernumerary crossveins on the forewing but its forewing is truncate apically rather than rounded.
