[Figs. 22, 71] <b>Type material.</b> Holotype ♂: <b>New Zealand</b>, South Is., OL, East Matukituki valley, Malaise at forest edge, 1200`, 31/i–4/ii/1987, JWE [NZAC]. Paratypes: 2♂, 1♀ same data as holotype [NZAC, NMWC]; 1♂, MB, 42° 32`S, 172°24`E, Glen Hope Station, site code ' Meat Safe', FIT on ground in forest, 27/i–9/ii/2001, RKD [NMWC]; 1♀, MB, 42° 30`S, 172° 24`E, Glen Hope Station, site code ' St. James', FIT in canopy, 31/i–13/ii/ 2001, RKD [NMWC]. <b>Additional material:</b> 2♀, NC, both very damaged from 42° 39`S, 172° 23`E, Glen Wye Station, Kakapo Brook Val., site code ' Bush Hut', FIT in canopy, 19/xii/2000 – 1/i/2001, RKD [NMWC] and NC, 42° 37`S, 172° 21`E, Glen Wye Station, Hope River Val., site code ' Front Dismal', FIT on ground in forest, 1–17/xii/ 2000, RKD [NMWC]. <b>Etymology:</b> specific epithet derives from <i>atrocitas</i> (Latin) meaning fierceness. <b>Description. Male:</b> Length 1.5–2.0mm (wet specimens).Very similar to <i>C. tainuia</i> but differing as follows. <i>Head</i>: yellowish brown; antenna brown, postpedicel 3X as long as wide, arista 2.5X as long. <i>Thorax</i>: ground colour brownish orange (possibly darker in life); setae black similar to <i>C. tainuia</i> (but some setae missing in types), <i>unp</i> conspicuously long and strong. <i>Legs</i>: yellow; C 1 0.8–0.9X as long as thorax; F 1 more strongly inflated than in <i>tainuia</i>, about 3.0–3.2X as long as wide. Femoral formula 4(4–4)/19(18–22)/ 13(11–15)/4(4–5) with <i>av</i> and <i>pv</i> spines yellowish and basal 5–6 denticles in <i>pv</i> series black and point-like, becoming yellowish and bristle-like distally; 2 strong yellowish bristles basally contiguous with line of <i>av</i> spines (but lacking any basal bristles contiguous with line of <i>pv</i> spines). <i>Abdomen</i>: similarly coloured as thorax, tergite 5 with a fan of strong black setae on posterior margin. Hypopygium (Fig. 22) strongly reflexed anteriorly with apex of epandrial lamellae reaching to tergite 5. Hypandrium broad, keel shaped, rather sparsely haired. Epandrial lobes bluntly trifid apically; the posterior lobe weakly developed but hairy throughout; median lobe more strongly developed, bare but for a cluster of short black rather flattened setae apically at margin; anterior lobe fused with cercus, folded inwardly at tip and bearing dense brush of black flattened bristles. Postgonite (?) with thick mat of blunt rod-like setae. Phallus rather abruptly curved halfway along exposed section, more gently sinuous distally. <i>Wing</i>: similar to <i>C. tainuia</i>, veins yellowish. Halteres dirty white. <b>Description. Female:</b> similar to the male. Femoral formula 4(4–4)/20.5(20–21)/14(12–15)/4(4–5). Pregenital sternite similar to <i>C. tainuia</i> but narrower apically (Fig. 71). <b>Comments.</b> This is an orange-yellow species of the <i>C. modica</i> -group, similar to <i>C. tainuia</i> but with epandrial lobes bluntly trifid and female pregenital sternite narrower apically. It is currently known only from forests of the South Island during December to March inclusive.
