Genus Caledonina Desutter-Grandcolas View in CoL , n. gen.
TYPE SPECIES. — Caledonina chopardi Desutter-Grandcolas , n. sp.
ILLUSTRATIONS. — Habitus: Fig. 9A View FIG . Male genitalia: Fig. 9 View FIG F-H.
ETYMOLOGY. — Genus named after its geographical origin.
DIAGNOSIS. — Very small (body less than 5 mm long), brightly coloured species; head and DD light orange and brown ( Fig. 9A, B View FIG ); LL shiny black; FW lateral field party dark brown; legs light yellow. Pronotum transverse, much wider than long. TI with a large outer tympanum, no inner tympanum. TII with two long apical spurs. TIII with three pairs of apical spurs; four inner and three outer subapical spurs. Tarsi all long, longer than half tibiae.
Male. FWs long, covering almost the whole abdomen. Stridulum complete; mirror partly reticulated. TIII upper inner subapical spur short, wide and thick (probably glandular, as in Pteronemobiini : Fig. 8D View FIG ). Male genitalia wide, with short pseudepiphallic sclerite; pseudepiphallic median distal lobes very well developed, turgescent and covered with long setae; pseudepiphallic lateral lobes almost as long as median lobes, connected both to median lobes and to pseudepiphallic parameres.
Female. Unknown.
DISTRIBUTION. — Endemic to New Caledonia; known from Aoupinié mountains only.
HABITAT. — See below Caledonina chopardi, Desutter-Grandcolas , n. gen., n. sp.
REMARKS
In the molecular phylogeny proposed by Chintauan-Marquier et al. (2013, 2016), Caledonina Desutter-Grandcolas , n. gen. is the sister group of Koghiella . Caledonina Desutter-Grandcolas , n. gen. is however closer to Bobilla , not included in the molecular phylogeny. Both genera present very similar male genitalia, especially the pseudepiphallic median lobes; they differ by several morphological characters, such as the number of TIII subapical spurs (four outer in Caledonina Desutter-Grandcolas , n. gen. against three in Bobilla ; TIII most basal inner subapical spur glandular in Caledonina Desutter-Grandcolas , n. gen. but not so in Bobilla ). These data validate the occurrence of species with a tibial gland in males within the Nemobiini , a characters used up to now to separate Pteronemobiini .
DESCRIPTION
Very small (body less than 5 mm long in males), brightly coloured species. Eyes wide but not protruding; distance between epistemal suture and lower margin of eye well shorter than eye mid width. Ocelli set as a low triangle, the laterals much bigger than the median; median ocellus subapical. Maxillary palpi ( Fig. 8B View FIG ) a little elongate; joint 4 very short compared to joints 3 and 5; joint 5 the longest, regularly widened toward apex but not very wide, as in Kanakinemobius Desutter-Grandcolas, 2016 . Pronotum much wider than long ( Fig. 9A View FIG ); LL squared. TI with a large outer tympanum, no inner tympanum; two apical spurs, ventral, the outer small, the inner much longer. TII with two, long and ventral, apical spurs. TIII with three outer and four inner subapical spurs, all alternate; outer spurs more equal in size than the inners, the first (distal) inner subapical spur longer than all subapical spurs, the fourth (basal) inner subapical spur small and short ( Fig. 8D View FIG ), resembling the glandular spur of Pteronemobiini (at least in males). TIII with three inner and three outer apical spurs; ventral spurs much shorter than median and dorsal spurs, the inner longer than the outer; median spur the longest on outer side, nearly twice as long as dorsal outer spur, but shorter than dorsal and median inner spurs; these last spurs longer than all other apical and subapical spurs, and reaching or extending slightly beyond hindbasitarsomere mid length. Tarsi all very long, longer than tibiae mid length.
Coloration ( Fig. 9 View FIG A-D)
Variegated light orange and light brown; LL shining black; FW lateral field upper part dark brown. Legs light yellow, FIII somewhat darker. Tergites black with a yellow dot on each side, sternites light yellow. Cerci light yellowish brown, darker at base.
Male
TIII fourth (most basal) inner subapical spur ( Fig. 9E View FIG ) short, thick and blunt distally (glandular). FWs not covering whole abdomen ( Fig. 9A, B View FIG ). Stridulum complete, but apical field and mirror partly filled with large reticulation. Limit between lateral and dorsal fields made by MP; file very short, running on about half FW width only; a wide area between file and CuA, with a faint CuP running between. FWs truncate distally, with a very short median fan. Lateral field with four longitudinal parallel veins, including MA and R. Subgenital plate long and high, but transverse, and truncate distally ( Fig. 8F View FIG ).
Male genitalia ( Fig. 9 View FIG F-H)
Pseudepiphallic sclerite short; pseudepiphallic median distal lobes very well developed, turgescent and covered with long setae; median lobes making the V-shaped distal margin of pseudepiphallus; pseudepiphallic lateral lobes almost as long as median lobes, connected both to median lobes and to pseudepiphallic parameres.

DESCRIPTION
In addition to the characters of the genus: Coloration. Head dorsum and cheeks light orange, with light brown longitudinal stripes; a wide brown stripe behind each eye.
