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

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.
