Figs 39–41 View FIGURES 36 – 44 , 52 View FIGURES 45 – 53

Diagnosis. Wellsomina ampulla can be separated from other Wellsomina species by the broad, rounded mesal flange or lobe on each superior appendage.

Description. Head, body and wings light brown; wings similar to those of W. stuarti ( Fig. 7 View FIGURES 7 – 11 ), length of forewing: male 2.6–2.9 mm, female 3.0– 3.1 mm. Wing venation: forewing length about 3.4 times width, each with forks 2, 3, 4 and 5 present; fork 2 relatively short, fork 2 footstalk relatively long, length about 1.4–2.2 times length of cross-vein r -m, length of fork 2 about 1.6–1.9 times length of fork 3; fork 3 very short, length of fork 3 about 0.6–0.7 times length of footstalk, footstalk of fork 3 very long, length about 3.5–4.1 times length of cross-vein m. Hind wing length about 4 times width, each with forks 2, 3 and fork 5 present, all short; fork 2 footstalk relatively long, length about 3.2 times length of cross-vein r -m.

Male. Tergum X membranous. Superior appendages complex, in dorsal view each with broad, rounded dorsomesal flange or lobe with spines mesally, ventrodistal lobe with 1 spine apically ( Fig. 41 View FIGURES 36 – 44 ); in lateral view superior appendages bifid, club shaped. Phallus simple, tube-like, truncated apically ( Fig. 39 View FIGURES 36 – 44 ). Inferior appendages strongly depressed, in ventral view fused, flask shaped, rounded laterally, with pair of digitiform processes distally, separated by narrow notch ( Fig. 40 View FIGURES 36 – 44 ); in lateral view slender, narrowed slightly in distal 1/ 4th ( Fig. 39 View FIGURES 36 – 44 ).

Female. Genitalia with abdominal sternite VIII relatively broad, basally with relatively short, slender digitiform mesal process; segment IX relatively short, broad-based, tapered distally; segment X relatively long, slender with 1 pair of small cerci ( Fig. 52 View FIGURES 45 – 53 ).

Holotype male: Queensland, Dulhunty R., Telegraph Crossing, 11°50'S, 142°30'E, 10 Feb 1992, Cartwright and Wells ( NMV, T- 20843).

Paratypes: 1 male (specimen CT-437 figured), 5 females (specimen CT-520 figured), same site and collectors as holotype, 8–9 Feb 1992.

Etymology. Ampulla - Latin word for flask (inferior appendages).

Remarks. Wellsomina ampulla is an uncommon species taken only at the type locality on Cape York Peninsula, north-eastern Queensland (latitude 11°50'S).
