Micranops australasiaticus, sp. nov. (Figs 59–61) Type specimens: Holotype ♂, Democratic Republic of Timor-Leste: Maupitine (8.47319S, 127.14378E), 24.V.2012 (AMS). Paratypes (2 specimens): 1 ♂, Australia, Northern Territory, Nourlangie Creek: 8 km N Mt Cahill (12.48S, 132.42E), 26.X.1972, leg. Britton (ANIC); 1 ♀, same data, leg. Colless (ANIC). Description: Macrophthalmous species with palisade fringe of abdominal tergite VII; examined specimens macropterous with elytral sutural length about as long as pronotum and functional metathoracic wings. Body color medium brown with slightly lighter brown pronotum; appendages light brown. Body surface subnitid with very fine, dense, setose punctation. Head about 1.2 times longer than wide, with moderately convex temples and straight posterior margin. Eyes 0.48–0.54 times as long as temples. Nuchal groove 0.25 times as wide as greatest head width. Trichobothrial cavity guttiform, with tapered anterior end connected to dorsoposterior margin of eye. Antenna from moderately elongate pedicellus and antennomere 3 gradually wider toward somewhat transverse penultimate antennomeres; antennomere 10 about 0.8 times, antennomere 11 about 1.4 times as long as wide. Total body length 2.0–2.3 mm; forebody length 1.2–1.3 mm. Male: Protarsomeres 1–4 dilated, approximately twice as wide as long. Abdominal sternite VII without diagnostic characters. Abdominal sternite VIII with subbasal ridge straight and posterior margin triangularly incised to approximately 0.2 of sternite length; lateral setae long, up to 0.3 times as long as sternite length (cf. Fig. 158). Aedeagus with lobe-bearing apical portion occupying about 0.25 of aedeagal length (Fig. 59), in dorsal view long-oval, about three times as long as wide (Fig. 61); phallobase extended beyond base of ventral process, there moderately concave ventrally (Fig. 59) and almost straight laterally (Fig. 61). Apical lobes each with sublateral, subapical group of very fine setules (Fig. 60), in ventral view with round, narrow apex (Fig. 60), and ventrally extended into long, subtriangular, hyaline lobe (Fig. 59); in dorsal view, apical lobes parallel laterally, but evenly, convexly narrowed toward round apex (Fig. 61). Dorsal lobe in lateral view occupying about 0.15 of aedeagal length (Fig. 59), in dorsal view triangular with subacute apex (Fig. 61). Ventral lobe absent. Ventromedial endophallic lobe long triangular with moderately distad curved, subacute apex, running between ventral extensions of apical lobes, and protruding beyond these extensions ventrally and proximally (Fig. 59); distal margin of ventromedial endophallic lobe strongly sclerotized and bearing two minute denticles (Fig. 59). Endophallic sclerites as in Figs 59–61. Ventral process reaching ventromedial endophallic lobe, in lateral view narrow, at widest point about 0.4 times as wide as aedeagus at same level, evenly curved distad, but in apical portion curved ventrad and gradually tapered toward narrow apical end (Fig. 59); in ventral view, ventral process at base about 0.5 times as wide as aedeagus at same level, after that gradually widened toward broad, subtruncate end with short, pointed median tip, widest subapically, here about 1.3 times as wide as aedeagus at same level (Fig. 60) and notably protruding over contour of aedeagus (Figs 60, 61). Dorsomidlongitudinal split including dorsodistal opening occupying about 0.7 of length of phallobase (Figs 59, 61); latter therefore over same length collapsed in dry specimens (Fig. 59). Postforamen notably projecting distoventrad (Fig. 59). Circoforamen about 2.5 times as long as median foramen (Fig. 60). Length of aedeagus 0.37 mm. Female: Protarsomeres 1–4 somewhat dilated, less than twice as wide as long. Distribution: Micranops australasiaticus is known from northern Australia and the island of Timor and thus an Australasian faunal element. Bionomics: Micranops australasiaticus was caught in flight with yellow pans and light traps. Etymology: The epithet australasiaticus [Latinized adjective (“the Australasian”), derived from Australasia] refers to the distribution of this new species in the Australasian biogeographical region.
