description: Neboissomina persona sp. nov.
Figs 3–5, 24
Diagnosis. Neboissomina persona is most similar to, N. krokale and N. mida, in the inferior appendages which are fused into large, ovoid plates, however in N. persona the apex is truncate distally separating it from the 2 other species where the apices are tapered into a single point.
Description. Head, body, and wings light brown, abdomen paler ventrally; wings similar to those of N. jardinei, new species (Fig. 2); length of each forewing: male 2.6–3.5 mm, female 2.6–3.4 mm, about 3.3 times width; length of each hind wing 3.4–3.7 times width. Wing venation: Each forewing with forks 2, 3, 4 and 5 present; fork 2 length 1.4–1.8 times length of fork 3; fork 3 with variable footstalk, fork 3 length 1.3–4.5 times length of footstalk, footstalk fork 3 length 1.1–2.6 times length of cross-vein m; cross-veins r-m and m nearly contiguous at fork 3, r-m and m separated by 0.4–1.0 times length of cross-vein m; fork 5 length about 1.7 times length of fork 4. Hind wings each with forks 2, 3 and 5 present; footstalk of fork 2 length 0.0–2.4 times length of cross-vein r-m, fork 2 length 1.2–1.5 times length of fork 3.
Male. Tergum X membranous, with 1 pair of long, slender dorsal processes, widely separated at base, converging distally (Fig. 5). Superior appendages short, robust, each with length about 3 times width (Fig. 3) in lateral view, length about 2.5 times width in dorsal view, slightly dilated distally (Fig. 5); pair of long, dorso-ventrally flattened (depressed) processes (mesal processes of tergum X) ventro-basal of superior appendages. Phallus simple, tube-like, distal part dorso-ventrally flattened; with pair of long, slender processes (phallic guides) arising from near bases of inferior appendages (Fig. 3). Inferior appendages longer than superior appendages, fused; in ventral view forming large, ovoid shield, truncated distally, length about twice width (Fig. 4); in lateral view slender, about 5 times longer than wide, dilated near middle (Fig. 3).
Female. Genitalia with pair of small robust obliquely truncate lobes on sternite VIII (Fig. 24).

Etymology. Persona, “mask” in Latin, refers to the shape and markings on the fused inferior appendages of the male genitalia.
Distribution. Neboissomina persona has been collected from 7 localities in northeastern Queensland (latitudinal range 16°49'– 18°57'S).
