Neboissomina , new genus

Type species. Neboissomina jardinei , new species, by original designation.

Diagnosis. Male genitalia with inferior appendages, fused, forming a large ovoid or subquadrate plate; with a pair of long, dorso-ventrally flattened mesal processes of tergum X. Female genitalia typically with a pair of small lobes or occasionally without obvious lobes on sternite VIII. The forewings have both forks 2 and 3 long and with short footstalks, and the hind wings with fork 3 longer than the footstalk. Head with occipital warts aligned transversely.

Description. Adults small; length of each forewing: males 2.4–3.1 mm, females 2.7–3.1 mm; forewings narrow, each with length 3.3–4.0 times width; head dorsally with occipital warts aligned transversely, scutellum with heart-shaped scutal wart (Fig. 1). Wing venation: Each forewing with R1 divided distally (sometimes reunited near wing margin), forks 2, 3, 4 and 5 present; fork 2 long, sessile, length of fork 2 ranges from 1.3–2.3 times length of fork 3; fork 2 nygma absent; fork 3 length 0.9–4.5 times length of footstalk, footstalk of fork 3 length 2.6–7.0 times length of cross-vein m, cross-veins r-m and m usually contiguous or nearly meeting at fork 3; fork 4 slightly shorter than fork 3; discoidal cell closed, length about 3 times width. Hind wings each with length 3.8–4.7 times width, forks 2, 3 and 5 present, fork 2 footstalk length 2.0–5.0 times length of cross-vein r-m, discoidal cell length about 3 times width, 2 anal veins (Fig. 2). Male genitalia with superior appendages in dorsal view club shaped with slightly dilated apices; inferior appendages fused, forming a large, ovoid or subquadrate plate with pair of long, dorso-ventrally flattened (depressed) processes (mesal processes of tergum X) ventro-basal of superior appendages (Figs 3– 23). Female genitalia typically with a pair of small lobes on sternite VIII, segment IX long, tapering distally, with several pairs of hairs; and segment X short, about half length of segment IX, with pair of cerci (Figs 24–28).

Etymology. Neboissomina - named after Dr Arturs Neboiss, for his great contributions to the study of Trichoptera in Australia, combined with part of generic name Ecnomina (Greek, “little outlaw”). The gender of Neboissomina is feminine.
