Tanytarsus fuscithorax Skuse, 1889 View in CoL

( Figures 3 View FIGURE 3 and 4 View FIGURE 4 C)

Material examined. NEW CALEDONIA, Nouméa, Magenta, 22°15’47.79” S / 166°28’0.81” E, 23 February 2008, at light, 1 adult male, leg. R. Dobosz.

Diagnostic description. Adult male. Wing length 1290 Μm. AR 0.91. Frontal tubercles c. 15 Μm long. Lengths of palpomeres 2–5 (in Μm): 40, 103, 127, 206. Clypeus with 18 setae. Ac 17, Dc 9, Pa 1, Scts 6. Shape of wing, venation pattern and chaetotaxy typical for the genus, as shown in Fig. 4 View FIGURE 4 C. Combs of mid and hind leg tibiae composed of teeth up to 15 Μm long, each comb with spur: longer spur bent subapically (c. 30 Μm and 40 Μm long on mid and hind leg tibia, respectively), shorter spur straight (c. 20 Μm and 35 Μm long on mid and hind leg tibia respectively). Basitarsus of mid leg with 5–6 hook-shaped sensilla chaetica. For lengths of leg segments and leg ratios see Table 4 View TABLE 4 . Hypopygium as figured by Glover (1973, fig. 46a–d), Ekrem (2001, figs 25–27), and as shown in Fig. 3 View FIGURE 3 .

Remarks. The species was redescribed in detail by Ekrem (2001), thus only additional illustrations are presented here. The examined male fits well the proposed combination of diagnostic characters (op. cit.) having well developed frontal tubercles, a single median seta and extensive microtrichia free area around anal point, large oval spinulae arranged in row between well developed crests, oval and bare superior volsella with a distinct lip, and no digitus; foliate lamellae of the median volsella are folded and overlapping in natural position, as shown in Fig. 3 View FIGURE 3 C. This eurytolerant species is probably widely distributed in Australasia and in the Oriental region (op cit.).
