(Figs. 13, 18)
Diagnosis. Campsicnemus hihiroa is characterized from other species in the hihiroa group by the two pairs of extremely long setae on the short, cylindrical mid basitarsus. The other species of this group have either one pair (C. dytei) or one long seta and one short way seta (C. taratara).
Description. Male. Body length: 2.7–2.9 mm. Wing length: 2.3–2.5 mm.
Head. Black, face dark brown to black with reddish highlights, paler brown near clypeus; oc and vt black, about one-half length of antennal arista; front, occiput, and vertex black with blue highlights; face constricted at middle, almost holoptic, eyes separated below antennae by width of 1–2 ommatidia; palp small, dark brown; proboscis brown, extending below eye in lateral view; antennal segments black to brown; postpedicel long, lanceolate-conical, length about 2.5 x width; arista slightly longer than head height.
Thorax: Mesoscutum, scutellum, and pleura brown throughout, with a few metallic bluish highlights dorsolaterally; thoracic setae black: 1 + 4 dc; 2 np; 2 ph; 1 pa; 1 + 1 sc; ac absent; halter stem and knob white.
Legs: CI yellowish, CII and CIII brown, slightly paler than surrounding pleura; FI and FII yellowish, FIII yellowish brown; remainder of legs brown; TI with apical tibial comb remainder of foreleg unmodified, without MSSC; FII with 4–5 strong black setae subbasally on ventral surface; hind leg unmodified, without MSSC; TiII with 4 long setae in middle and single strong, slightly sinuous seta subapically on mesal surface (MSSC), single strong setae apically on lateral surface. IIt1 (Fig. xx) short, about one-half length of IIt2, with 2 very long strong black setae on mesal surface (length subequal to second tarsomere), 2 shorter strong brown setae on posterolateral surface (MSSC). Remainder of leg segments without MSSC.
Wing: pale smoky throughout; posterior crossvein perpendicular to vein M.
Abdomen. Dark brown with short black hairs dorsally on each tergite, a few longer hairs laterally; tergal interstices whitish; sternites yellowish brown. Hypopygium brown with paler brown cerci, not dissected.
Female. As in male except for lack of MSSC; postpedicel length about 1.5 x width; legs normal, without modifications; FI and FII brown.

Polhemus; 1 ɗ [BPBM1013205], Mt. Temetiu, 3700 ft [1128 m], 9°47'56"S, 139°04'45"W, 14 Aug 2001, pyrethrin fog on mossy trees, D.A. Polhemus; 1ɗ [BPBM1013206], Temetiu Ridge, at trail crossing, 3650 ft [1112 m], 9°47'54"S, 139°04'44"W, 26 Oct 1999, mossy stems and branches, J.T. & D.A. Polhemus. Holotype in BPBM. Paratypes in BPBM and USNM.
Etymology. The specific epithet derives from the Tahitian hihi = “eye lash, whisker” + roa = “long”; referring to the long setae on the mid basitarsus.
