Cyamops femoctenidius

description: <i>Cyamops femoctenidius</i>, new species Figure 15 DIAGNOSIS: Face with peristomal setae, slight vertical ridge; arista with 5–6 basal branches bifurcate (secondary branches very small); legs almost entirely yellow; forefemur with ctenidium, mesocoxa with small comb of thick setae on posterior margin; male terminalia with V-shaped hypandrium and aedeagal apodemes, left surstylus long, digitate, nearly straight, length 4.8X greatest width. DESCRIPTION: Similar to the description given for <i>C. femobrunneus</i> with the exception of the following features: frons darker, more extensive velvety black; pedicel and basal flagellomere with dark infuscation; proximal 4–5 dorsal branches of arista with small secondary branches; face with fewer parafacial setae, only 1 larger and 2 minute pairs; silvery microtomentum covers most of face and is more extensive on frontal orbital plates; microtomentum very sparse on fore coxae, midcoxae with row (‘‘comb’’) of thick setae on posterior margin; legs virtually entirely yellow; forefemur with row of ca. 7 small, spinulelike setae on mesal surface of distal half; hind femur with ventral row ca. 10 fine, light, stiff setae; scutum deep, dark brown; anterior portion of male scutum with some polished areas; tergite VII of male with left lobe pointed (not blunt); left surstylus long and slender, but straight, right surstylus short and folded. TYPES: Holotype, male: <b>Taveuni</b>: Cakaudrove Prov., 5.6 km SE Tavuki Vlg, Devo Peak 1187 m, 31.X–14.X1.2002, Malaise 1, coll. E. Schlinger and M. Tokota’a, 16.843 <i>°</i> S, 179.965 <i>°</i> W, FBA056938 (not dissected). Paratypes: 34 males, same locality, dates: 2– 10.X.2002, 24–31.X.2002, 31.X–14.XI.2002, 14–21.XI.2002. 3 males dissected (nos. 60, 65, 66). Holotype and some paratypes in BPBM, other paratypes in AMNH. ETYMOLOGY: From <i>femur</i> and <i>ctenidium</i>, in reference to the row of fine, thornlike setae (ctenidium) on the forefemur. This feature occurs sporadically in the genus. COMMENTS: This species appears close to two Australian species and a Papuan one, based on the peristomal setae, forefemoral ctenidium, the bifurcate aristal branches, and some aspects of the male genitalia (Baptista and Mathis, 2000; Khoo, 1984). These are <i>Cyamops papuensis</i> Baptista and Mathis (from Papua New Guinea), <i>C. claudiensis</i> Khoo (from Queensland, Australia), and the comb of mescoxal setae is similar to that of <i>C. pectinatus</i> Khoo from eastern Australia.
