27. Chelipoda trepida Collin View in CoL
[ Figs. 62 View FIGURES 56–62 , 112 View FIGURES 104–116 ]
Chelipoda trepida Collin, 1928: 35–36 View in CoL .
Type material. Collin (1928) described Chelipoda trepida from two males from Ohakune, x–xi.1922, T. R. Harris [ BMNH]. Ohakune is in: New Zealand, North Island, RI. One of these males in best condition is here
designated lectotype. The other male is here designated paralectotype.
Additional material: 8♂, 18♀, from WO, TO, CL and HB [ NZAC, NMWC] .
Description. Male: length 1.8–2.2mm (wet material).
Head: blackish dusted grey, paler on face; subspherical, not strongly dorsoventrally flattened, rather quadrate behind; eyes narrowly separated below antennae, widening towards mouth; ocl very strong, 2X as long as verticals; vt2 diagonally behind vt1; upo black, rather irregular, as long as but clearly not contiguous with verticals; lpo becoming longer and yellowish below, a patch of pile behind mouth margin. Antennae ( Fig. 112 View FIGURES 104–116 ) dark, basal segments slightly paler; scape short bearing a distinct dorsal seta extending to tip of pedicel; postpedicel pubescent, 3X as long as wide, apically pointed, outer edge slightly concave and inner edge slightly convex viewed from above; arista as long as postpedicel. Mouthparts yellowish brown.
Thorax: ground colour yellowish brown to blackish, yellowish stripes laterally on scutum between pprnlb and base of wing and on pleura between base of C 1 and haltere. Thoracic dorsum dusted grey, a broad dark median stripe when viewed from behind and 1–3 dark stripes when seen from in front, on pleura dusting stripes follow and sometimes emphasize pattern of ground colour. Thoracic setae black; dc2, dc3, pprn, unp, sa and sct strong; dc1 and lnp weaker, dc4 absent, dc5 minute; a pair of minute acr in front.
Legs: yellow, tarsi darker apically. C 1 0.9X as long as thorax with only short hairs and bristles. F 1 1.1X as long as C 1, moderately inflated, widest 0.3–0.4 from base, practically only 2 rows of bristles beneath; pv row of rather spine-like denticles virtually coincident with series of 4–5 larger spine; av spines strong basally, much smaller distally, a small ventral bristle 0.1 from base. T 1 0.7X as long as F 1, a few perpendicular cilia alongside linear series of minute adpressed denticles and erect hairs ventrally; at2 as long as at3.
Wing: venation simple, cell cup closed, but vein A 1 faint (particularly basally) and continued weakly for a short distance beyond junction with CuA 2. Halteres pale.
Abdomen: brownish dorsally, paler below; distinct bristly hairs on tergites 1–5, sternites with shorter hairs. Terminalia ( Fig. 62 View FIGURES 56–62 ) forwardly reflexed; epandrium and hypandrium separate; epandrium divided, lobes long oblong, rather flattened apically with long setae on posterior margin; hypandrium inverted heart-shaped, a pair of very strong and several weaker setae posteriorly; subepandrial process long, narrow, pointed, curved anteriorly towards tip; cerci free, small with long hairs apically; phallus rather broad, weakly sinusoidal, not strongly curved.
Description. Female: similar to male but larger (2.0– 2.5mm). Basal antennal segments distinctly paler than postpedicel and arista slightly longer. Abdomen with shorter hairs most conspicuous on tergites 1–3. Terminal papillae dark brown with dark hairs.
Comments. C. trepida has a dark thorax with dirty yellowish stripes on the scutum and pleura, F 1 with practically only 2 rows of ventral setae, postpedicel moderately long and slightly curved, verticals not contiguous with upo and cup closed with A 1 faint. This species is known with certainty only from forested areas of North Island with capture dates in February, April, May, September, October and November with an altitude range of sea level to approximately 500 m. However, two females [in NMWC] collected from subalpine scrub in South Island’s Mt Aspiring national park may be this species; these specimens are very dark and C 1 has a dark stripe anteriorly .
