Description
Stirellus lesioensis sp. nov.
(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.
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.
