Stirellus lesioensis View in CoL sp. nov.

( Figs 23–24 View FIGURE 23 View FIGURE 24 )

Description. Length. Male: 4.1–4.2mm ..

Coloration. General color stramineous with brown or orange-red marks ( Fig. 23 View FIGURE 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 View FIGURE 23 ). Frontoclypeus brown with sordid white arcs reaching only part way across ( Fig. 23D, E View FIGURE 23 ). Forewing translucent with fuscous tint and white veins ( Fig. 23 View FIGURE 23 A–C). Femora and tibiae with dark brown marks ( Fig. 23C View FIGURE 23 ). 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 View FIGURE 23 A–C). Crown with anterior margin forming right angle in dorsal view, slightly longer than width between eyes ( Fig. 23A, B View FIGURE 23 ). Anteclypeus parallel-sided, extending slightly beyond normal curve of genae ( Fig. 23D, E View FIGURE 23 ). Pronotum median length slightly longer than median length of crown. Mesonotum and scutellum together nearly as long as pronotum ( Fig. 23A, B View FIGURE 23 ). Forewing macropterous, with few to many supernumerary crossveins ( Fig. 23 View FIGURE 23 A–C).

Male genitalia. Pygofer side long, with few macrosetae dorsally, dorsal margin slightly concave distally, posterior margin nearly truncate ( Fig. 24A View FIGURE 24 ). Subgenital plate slightly concave laterally, macrosetae uniseriate laterally ( Fig. 24C View FIGURE 24 ). Style apophysis digitate, laterallylaterally curved, preapicalpreapical lobelobe poorlypoorly developed, roundedrounded ( Fig. 24D View FIGURE 24 ). Con-Con-Connective Y-shaped, stem broad and shorter than arms ( Fig. 24E View FIGURE 24 ). Aedeagal shaft bent dorsad near base, long, very slender, sinuate in lateral view, apex abruptly tapered to point in dorsal view ( Fig. 24 View FIGURE 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 View FIGURE 23 ), presence of supernumerary crossveins on the forewing, and the relatively long, apically truncate male pygofer ( Fig. 24A, B View FIGURE 24 ). The Australian species S. hanuala also has supernumerary crossveins on the forewing but its forewing is truncate apically rather than rounded.
