( Figs 1D , 6 A–B) Type material. Holotype , male ( BPBM ): “ FIJI : Taveuni , Cakaudrove Prov. , / 5.6km SE Tavuki Village , Devo / Peak , 1187m .[ -16.843 , -179.955 ], / 24.X.2002 – 31.X.2002 , Malaise: M01 / E.I. Schlinger. M. Tokotaa. FBA201203” . Paratype : 1 male ( BPBM ): same data as above but inventory number FBA201204 . Diagnosis. Body elongate, depressed, identification possible only on the basis of male genital features: parameres much longer than basal portion of tegmen; apical portion of pala long and strongly narrowed with short apical processes, length of apical processes of penis equal. Description. Holotype , male. Body elongate oval, depressed, shining, covered with brownish setae, uniformly brown. Head of moderate size, flattened, shiny, covered with small punctures separated by ca. 1.0 diameter; clypeus moderately long, slightly expanded antero-laterally, gently arcuate in front margin. Eyes moderate in size, prominent; head ca. 1.5× wider than interocular space. Antennae filiform, reaching basal 1/3 of elytra. Pronotum convex in mesal portion of the disc, punctures similar to those on head, separated by ca. 1.0 diameter; antero-lateral angles widely subtriangular; postero-lateral angles right-angled; posterior margin slightly bisinuate. Scutellar shield relatively small, punctate, equilateral-triangular. Elytra oval, sides subparallel in basal half, regularly rounded in posterior half, punctation stronger than on pronotum, punctures separated by ca. 0.5 diameter; humeri elevated. Hind tibial spurs slightly curved, dorsal one 0.7× as long as tarsomere 1, ventral one 0.4× as long as dorsal one. FIGURE 6. Scirtes spp., tegmen (A, C, E, F, J), penis, dorsal view (B, D, G–I, K). A–B) S. devoensis sp. nov. ; C–D) S. humeralis Pic; E–I) S. tokotaai sp. nov. ; J–K) S. veitchi Champion. Scale bar = 0.50 mm. Sternite VIII very small, transversely V-shaped (L 0.05 mm , W 0.12 mm). Sternite IX (L 0.18 mm , W 0.24 mm) V-shaped, apodemes not fused at base. Tergite VIII (L 0.38 mm , W 0.29 mm) with transversely rectangular apical plate, bearing a row of short setae on apical margin, apodemes as long as apical plate; tergite IX (L 0.37 mm , W 0.21 mm) with rectangular apical plate, apodemes ca. 2× longer than apical plate. Aedeagus asymmetrical. Tegmen (L 0.91 mm , W 0.13 mm) very long and narrow, Y-shaped ( Fig. 6A ). Penis (L 0.78 mm , W 0.23 mm) elongate, pala oval in basal portion, and strongly narrowed in apical portion, apex of pala with two hooked, asymmetrical, short processes with pointed apices ( Fig. 6B ). Female. Unknown. Variability. TL variable, ca. 2.3–2.6 mm . Measurements and ratios. Males (n=2): TL 2.27–2.60 mm ( 2.43 mm ), EL 1.93–2.27 mm ( 2.10 mm ), PL 0.40–0.53 mm ( 0.43 mm ), EW 1.47–1.57 mm ( 1.52 mm ), PW 1.10–1.20 mm ( 1.15 mm ), TL/EW 1.55–1.66 (1.61), PW/PL 2.25–2.75 (2.53), EL/EW 1.32–1.45 (1.38), EL/PL 4.25–4.83 (4.54), EW/PW 1.31–1.33 (1.29). Distribution. Known only from the type locality on Taveuni Island ( Fig. 9D ). Etymology. After Devo Peak, the type locality of the species. Remarks. A female specimen was found in the same locality, but as many species of Scirtes occur together, it was not certain if this was a female of Scirtes devoensis sp. nov. Genitalia of the specimen are illustrated ( Fig. 10 ) and briefly described in the ‘Discussion’ section.
