description: 34. <i>Chelipoda rangopango</i> sp. n. [Figs. 55, 79] <b>Type material</b>. Holotype ♂: <b>New Zealand</b>, South Is., NC, Glynn Wye Station, Kakapo Brook Val., site code ' Kakapo', 42° 39`S, 172° 23`E, FIT on ground in forest, 3–16/i/2001, RKD [NZAC]. Paratypes: 1♂, 1♀ same data as holotype; 1♂, 3♀ same data as holotype, on ground at forest edge, 6-20/xii/2000 [NZAC, NMWC]; 1♂ same data as holotype, site code ' Donut', 42° 39`S, 172° 22`E, 1–15/i/2001 [NMWC] and 1♀, FIT on ground in forest, 6–18/xii/2000 [NZAC]: North Is.; 1♂, 3♀, WO, Mt. Karioi, Raglan, Malaise by Wainui Str., 5–11/x/ 1985, 12–20/x/1985, 7–14/ix/1986, HAO [NMWC]; 2♂, 5♀, TO, Urewera NP, W of pass on SH 38, 760m, 5/ ix/1977, ES [NZAC]. <b>Etymology:</b> from the Maori; <i>rango</i>, fly; <i>pango</i>, black. <b>Description. Male:</b> length = 2.5–3.0mm. <i>Head</i>: subspherical, black, dusted greyish, setae black; verticals about as strong as <i>ocl</i>, not contiguous with <i>upo</i>; <i>lpo</i> becoming longer and brownish below, diverging from eye margin; no fine pile on lower occiput. Frons slightly produced anteriorly above antennae; eyes narrowly separated on face; hypostomal bridge rather large forming flange at back of head below occipital foramen. Antennae black, basal segments and postpedicel basally yellowish below; scape 2X as long as wide, a distinct dorsal seta reaching to end of pedicel; postpedicel strongly dorsoventrally flattened, 1.5X as long as wide in dorsal view (3X as long as wide in lateral view), arista 1.3X as long. Mouthparts yellowish brown. <i>Thorax</i>: (Fig. 79) black, all setae black and rather stout; <i>dc1</i> very short but strong, 0.2X as long as <i>dc2</i>; <i>dc2</i>, <i>dc3</i>, <i>unp</i>, <i>pprn</i> and <i>sa</i> strong; <i>dc4</i> and <i>ph</i> minute; <i>lnp</i> weaker than <i>unp</i> (sometimes still smaller bristle above and in front). <i>Legs</i>: blackish; tibiae, tarsi basally, femora apically and C 1 apically yellow; C 2 and C 3 yellowish brown. C 1 0.9X as long as thorax, only small bristly hairs anteriorly; F 1 1.2X length of C 1, not strongly inflated, widest 0.3 from base narrowing gradually distally; an <i>av</i> series of 10–11 denticle-like spines; <i>pv</i> series of 6–7 distinct spines (often with a few much smaller spines intermingled) longest basally and a larger ventral basal bristle 0.15–0.2 from base. T 1 0.8X length of F 1, almost linear, usual series of minute adpressed denticles and outstanding hairs ventrally; <i>at2</i> as long as <i>at3</i>. Legs otherwise with only short hairs and bristles. <i>Wing</i>: with simple venation, veins brown; cell <i>cup</i> closed but A 1 faint, especially basally. <i>Abdomen:</i> brownish to black, tergites with scattered fine black setae on disc, stronger on posterior margins, especially on tergite 5; sternites shorter haired. Terminalia (Fig. 55) reflexed dorsally, hypandrium not fused with epandrium; epandrial lobes separate, slightly overlapping hypandrium below, bearing conspicuous yellowish posteroapical setae; hypandrium inverted heart-shaped; subepandrial process rather short; postgonite <i>large</i>, broad with flattened crescent shaped apical lobe; cerci free, at least apically, distal margin irregular bearing distinct yellowish setae and a narrow finger-like process laterally; phallus rather broad, strongly curved near base. <b>Description. Female:</b> differing from male as follows. Antenna with arista longer, fully 1.5X as long as postpedicel; <i>lpo</i> yellowish, longer (almost as long as <i>ocl</i>); <i>dc1</i> larger, 0.5X length of <i>dc2</i>. Terminal papillae slender with long fine pale hairs. <b>Comments</b>. <i>C. rangopango</i> is a distinctive small dark species with two rows of setae beneath F 1 and all femora distinctly darkened with paler tips. It is known from just three widely distant forest and forest edge localities of the two major islands of New Zealand with capture dates from September to January. There are small differences in the male terminalia of the Urewera specimens (the apical lobe of postgonite being rather less pointed for example) but there is little doubt that they are the same species.
