Genus Bobilla Otte & Alexander, 1983

Bobilla Otte & Alexander, 1983: 693 .

TYPE SPECIES. — Nemobius bivittatus Walker, 1869 by original designation.

ILLUSTRATIONS. — Habitus: Fig. 4B ; Otte & Alexander 1983: fig. 133. Male genitalia: Otte & Alexander 1983: fig. 136. Calling songs: Otte & Alexander 1983: fig. 135.

EMENDED DIAGNOSIS. — Large nemobiines, with rounded head in front view. Eyes small and not at all protruding; distance between epistemal suture and lower margin of eye greater than eye mid width. Ocelli set as a flat triangle; all large, but median ocellus more protruding. Maxillary palpi elongate; joint 5 very little widened apically, truncate distally. Pronotum transverse in males, less so in females; anterior margin slightly concave, posterior margin convex; lateral lobe squared, more narrow distally.TI with a large outer tympanum; no inner tympanum; two long and ventral apical spurs. TII with three apical spurs, the dorsal inner small, the dorsal outer lacking. TIII with three inner and three outer subapical spurs, all alternate; spurs growing longer distally, outer spurs shorter than inner spurs. TIII with three inner and three outer apical spurs; ventral inner and outer spurs the smallest and subequal; median inner and outer spurs subequal; dorso-inner spur the longest, longer than half hindbasitarsomere. Basitarsomeres all long, tarsi longer than tibiae mid length.

Coloration. Variegated light brown, dark brown and yellow. Head dorsum and DD anterior part lighter. Face, cheeks and lateral field darker. Scape and first two antennal articles lightly coloured. Legs 1 and 2 and tibiae III annulated. Cerci long, divergent.

Male. FWs well-developed and overlapping, but not covering whole abdomen. Stridulatory apparatus complete. Mirror very short, not filled by apical reticulation; asymmetrical, wider toward right FW outer side, than toward its inner side. Apical field very reduced. Lateral field wide, with several closely-set, longitudinal parallel veins (five or six in material at hand). Subgenital plate wide and low. Male genitalia wide, with short pseudepiphallic sclerite; pseudepiphallic median distal lobes very short, which gives the genitalia of some species a very distinctive shape with a pseudepiphallus very short in mid dorsal area; pseudepiphallic lateral lobes bigger and longer laterally; pseudepiphallic parameres reduced.

Female. FWs variously reduced, sometimes hardly visible from beneath pronotum, overlapping or not on mid line. Ovipositor short, shorter than FIII; apex short, not widened; dorsal valves with longitudinal carina and more or less crenulated margin.

DISTRIBUTION. — Australia, New Zealand and New Caledonia.

HABITAT. — Bobilla species have been found by day and night in the leaf litter.
