6) Colocasiomyia kinabaluana Toda & Takano, sp. nov.

(Figs 9J, 15F, 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.

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

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). Female sternites V and VI longer than wide (Fig. 21B).

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). 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). Phallapodeme less sclerotized thin plate, nearly perpendicular to phallal axis (Fig. 21D).

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).

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). 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).

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) and the cladogram (BP = 100; Fig. 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.
