Diagnosis. The male of Neboissomina topendica sp. nov. is most similar to those of N. jardinei , N. kuranya Cartwright 2011 , N. riyala , and N. philsuteri Cartwright 2011 in possessing inferior appendages which are fused to form a single large sub-rectangular plate, but it is distinguished by the three, minute, acute projections apicolaterally and apicomesally on each inferior appendage, in ventral view.
Description, male. Spur formula: 3:4:4. Head, body, and wings light brown, abdomen paler ventrally; wings ( Fig. 6 View FIGURES 6–12 ) similar to those of N. jardinei ( Cartwright 2011, fig. 2), length of each forewing: male 2.3–3.1 mm, female 2.8–3.1 mm, length about 3.0 times width; length of each hind wing 3.2–3.3 times width. Wing venation: Each forewing with forks 2, 3, 4, and 5 present; fork 2 sessile, length about 1.5 times length of fork 3; fork 3 with length of fork about twice length of footstalk, fork 4 about 0.8 times length of fork 3, fork 5 about 1.6–1.7 times length of fork 4. Hind wings each with forks 2, 3, and 5 present; fork 2 sessile, its length about 1.7 times length of fork 3.
Male. Tergum X membranous, with pair of long, slender dorsal sclerotized processes converging near middle and diverging posteriorly ( Fig. 9 View FIGURES 6–12 ). Superior appendages short and robust ( Figs 7, 9 View FIGURES 6–12 ), in lateral view appearing subrectangular, very slightly tapered posteriorly, length about 2.8 times width, apices slightly rounded ( Fig. 7 View FIGURES 6–12 ), in dorsal view slightly dilated in posterior third ( Fig. 9 View FIGURES 6–12 ); pair of long, slender curved processes (mesal processes of tergum X) ventral to superior appendages. Phallus simple, tube-like ( Figs 7, 8 View FIGURES 6–12 ) with elongate, slender process partly embedded and emergent posteriorly ( Fig. 7 View FIGURES 6–12 ). Inferior appendages slightly longer than superior appendages, fused ( Figs 7–9 View FIGURES 6–12 ), in ventral view large, subrectangular shield, truncate posteriorly, length about 1.5 times width, with acute apicolateral corners and acute apicomesal projection ( Fig. 8 View FIGURES 6–12 ), in lateral view robust, tapered basally, very slightly tapered posteriorly, appearing sub-trapezoidal, length about 3 times width ( Fig. 7 View FIGURES 6–12 ).
Female. Unknown.
Etymology. Topendica —based on the colloquial regional name for the locality (Top End of the NT).
Remarks. At least thirty males of N. topendica have been collected from 3 localities in the Top End (latitude range 12.80– 14.59 °S), including sites in Kakadu NP and in the greater Darwin area.
