6) Colocasiomyia kinabaluana Toda & Takano View in CoL , sp. nov.

( Figs 9J View FIGURE 9 , 15F View FIGURE 15 , 21 View FIGURE 21 )

Colocasiomyia sp.2 aff. sulawesiana: Sultana et al., 2006: 694 ; Toda & Lakim, 2011: 264; Takano et al., 2011: 22; Takano et al., 2012: 559, Supplemental File 1; Fartyal et al., 2013, Fig. 6 View FIGURE 6 .

Diagnosis. A pair of processes on male abdominal sternite VI short (<0.05 mm), slightly divergent and curved inward, apically round ( Fig. 9J View FIGURE 9 ). Epandrium posteroventrally extended as ventral lobe roundish on apical margin ( Fig. 21C View FIGURE 21 ). Phallal sheath apicoventrally pointed like beak in lateral view, apically looking like arrowhead in ventral view ( Fig. 21D,E View FIGURE 21 ). Epiproct and hypoproct nearly flat ( Fig. 21F View FIGURE 21 ). Apical portion of oviscapt somewhat triangular ( Fig. 21G View FIGURE 21 ).

Description (♂ and ♀). Head. Supracervical setae 6–9 per side, distally more or less curved, longer than inner occipital setae. Cibarial, medial sensilla approximately 3 per side; posterior sensillum 1 per side. Supralateral setae outside prementum 3–4 per side.

Thorax. Anterior dorsocentral setae just beside transverse suture.

Abdomen. Male sternite III and IV longer than wide ( Fig. 21A View FIGURE 21 ). Female sternites V and VI longer than wide ( Fig. 21B View FIGURE 21 ).

Male terminalia. Epandrium pubescent except for anterior margin, anteroventral elongation and ventral portion, with 1–2 setae on dorsal portion and 21–23 setae thicker than cercal setae on ventral lobe of each side ( Fig. 21C View FIGURE 21 ). Cercus pubescent on dorsal 2/3 but not on anterior margin and ventral portion, with 38–39 setae, extended below, apically forming small lobe marginally fringed with small setae ( Fig. 21C View FIGURE 21 ). Phallapodeme less sclerotized thin plate, nearly perpendicular to phallal axis ( Fig. 21D View FIGURE 21 ).

Female terminalia. Hypoproct not pubescent. Oviscapt longer than phallus (apodeme + sheath), with 21–22 ovisensilla only on distal portion occupying less than 1/2 length of oviscapt ( Fig. 21G View FIGURE 21 ).

Indices (range of 10♂ and 10♀): FW/HW = 0.57–0.67, ch/o = 0.37–0.53, prorb = 0.94–1.15, rcorb = 0.25–0.54, vb = 0.23–0.38, dcl = 0.58–0.86, sctl = 0.68–0.86, sterno = 0.83–1.02, orbito = 0.44–0.84, dcp = 1.02–1.33, sctlp = 1.07–1.36, C = 1.68–2.38, 4c = 1.02–1.37, 4v = 1.45–1.86, 5x = 0.72–1.16, ac = 2.18–3.01, M = 0.35–0.48.

Puparium (3rd instar larva). Segments with stout spicules on ventral surface; anterior spiracle sessile, with a bundle of approximately 4 short branches; caudal segments elongate, with many small spicules, ending in a Vshaped pair of posterior spiracles ( Fig. 21H,I View FIGURE 21 ). Mouth hook less expanded medioventrally in lateral view; distal blade as long as basal portion, apically pointed, weakly curved downward, with two rows of small, acute teeth on submedial to subapical portion of ventral margin ( Fig. 21J View FIGURE 21 ).

Holotype. ♂ ( BORN), “ Kota Kinabalu , Sabah, Malaysia, 3.i.1999, ex Alocasia macrorrhizos, M.J. Toda ”.

Distribution. Borneo (Sabah), Philippines (Luzon, Samar, Leyte, Palawan).

Remarks. This species is coupled with C. sulawesiana in the molecular phylogenetic tree (BP = 87; Fig. 2 View FIGURE 2 ) and the cladogram (BP = 100; Fig. 13 View FIGURE 13 ), and shares the oviscapt longer than the phallus (apodeme + sheath) as a synapomorphy (ch.49-1) with it. However, they can be distinguished from each other by their diagnostic characters.

Etymology. Referring to the type locality.
