description: 30. Chelipoda australpina sp. n.   
[Fig. 15]  
 Type material. Holotype ♂: New Zealand, South Is., NC, Arthurs Pass, Kellys Ck., Nothofagus fusca forest, 28/xi/1977, ES [NZAC]. Paratypes: 1♂, 4♀, same data as holotype. The male paratype is greatly damaged, lacking its head.   
 Etymology: the specific epithet refers to the type locality in New Zealand’s Southern Alps.   
 Description. Male: length 3.0mm (dry specimens). Similar to C. oblata, differing as follows.   
 Head: with a few strong setae behind patch of fine pile on lower occiput; mouthparts blackish brown; Scape fully 2X as long as wide, postpedicel with longish hairs rather than fine pile, arista minutely pilose (as in C. oblata).   
 Thorax: ground colour of mesonotum uniformly dirty orange brown; pleura uniformly yellow, unstriped; rather thinly dusted grey, no dust stripes; mesonotal bristles black, dc2, dc3, unp, pprn, sa and sct strongly developed; dc1 absent; ph well developed but weaker than pprn.   
 Legs: similar yellow colour as pleura, becoming darker distally; C 1 0.7–0.8X as long as thorax, rather wide basally, narrowing slightly distally with 3 short distinct yellow bristles basally in front which are longest basally and merge with line of fine hairs beyond base. F 1 about as long as C 1, 1 very strong and 1 rather weaker yellowish bristle at base and series of distinct black pv bristles becoming shorter distally; an av series of about 17 small black bristles becoming somewhat denticle-like distally and in front of this a further series of erect anteriorly directed fine yellowish hairs becoming longer distally and ending abruptly 0.7 from base. T 1 as long as F 1, constricted to 0.5 maximum width on distal 0.2 where there are 2–3 short, black ventral spines; a linear series of minute and very inconspicuous adpressed denticles ventrally. Tarsi with at1 bearing short spines ventrally; at2 similar length as at3. Legs otherwise simple lacking remarkable chaetotaxy.   
 Wing: with simple venation, veins brown, membrane clear, Sc faint (R 2 +3 ending abruptly before tip in paratype ♂); vein A 1 very weakly present about end of CuA 2 and continued basally as a very faint darkening of membrane; costal bristle strong, three rather weaker but distinct setae on C between costal bristle and junction of C with R 1.   
 Abdomen: pale ventrally, black dorsally becoming yellowish apically; tergites with strong but sparse yellowish hairs especially on posterior margins; sternites more weakly haired. Terminalia (Fig. 15) yellow; hypandrium separate from and not overlapped by epandrium; epandrial lobes separate, quadrate, very small with long brownish setae above and behind; hypandrium produced posteriorly, bearing very long yellowish setae apically; cerci free, very long with whole of tip exposed above epandrium and covered with long bristly hairs; subepandrial process strongly sclerotized, large, broad, apically pointed; phallus rather broad, reflexed anteriorly near base and posteriorly near tip.   
 Description. Female: similar to male, differing as follows. F 1 with av and pv hairs and bristles more even sized, less denticle-like apically. T 1 shorter, 0.9X as long as F 1, not constricted distally, lacking subterminal black spines, ventral denticles rather larger and more conspicuous; at1 and at2 with shorter bristles. Wings simple, no supernumerary bristles on C between costal bristle and junction of C with R 1. Abdomen with terminal papillae narrow bearing shortish hairs.   
 Comment s. C. australpina is allied to C. oblinita and C. oblata but with the thorax unstriped and dc3 strong. Males have T 1 constricted distally. It is known only from Nothofagus fusca forest at the type locality, Arthurs Pass, South Island.
