description: 7) Colocasiomyia kotana Toda & Takano, sp. nov.
(Figs 9K, 15G, 22)
Colocasiomyia sp.1 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), widely separated, strongly divergent, apically somewhat pointed (Fig. 9K). Phallal sheath apically vertically dilated in lateral view, subapically without any appendages (Fig. 22D,E).
Description (♂ and ♀; not repeating characters common to C. kinabaluana sp. nov.). Head. Supracervical setae 6–7 per side, nearly straight, as long as inner occipital setae. Cibarial, posterior sensillum 0–1 per side. Supralateral setae outside prementum approximately 4 per side.
Male terminalia. Epandrium posteroventrally roundish on margin but not extended, with approximately 2 setae on lateral portion and 22–24 setae on ventral portion of each side (Fig. 22C). Cercus nearly oval, slightly constricted ventrosubapically, pubescent on dorsal 2/5, with 54–55 setae (Fig. 22C).
Female terminalia. Oviscapt shorter than phallus (apodeme + sheath), with 16–19 ovisensilla; distal portion spatulate, roundish apically (Fig. 22F).
Indices (range of 10♂ and 10♀): FW/HW = 0.55–0.65, ch/o = 0.36–0.53, prorb = 0.87–1.03, rcorb = 0.28–0.44, vb = 0.23–0.39, dcl = 0.57–0.93, sctl = 0.82–0.97, sterno = 0.67–0.99, orbito = 0.40–0.63, dcp = 1.13–1.34, sctlp = 1.27–1.64, C = 1.50–2.06, 4c = 1.07–1.29, 4v = 1.47–1.96, 5x = 0.83–1.12, ac = 2.69–3.40, M = 0.32–0.47.
Puparium (3rd instar larva). Anterior spiracle with a bundle of approximately 5 short branches (Fig. 22G).
Holotype. ♂ (BORN), “ Kota Kinabalu, Sabah, Malaysia, 12.viii.2004, ex Alocasia macrorrhizos, K.T. Takano ”.
Paratypes. Malaysia: 10♂, 10♀, same data as the holotype (BORN, SEHU). Philippines: 10♂, 10♀, Legaspi, S. Luzon, 13°08’52”N 123°44’04”E, 30.xi.2012, ex A. macrorrhizos, P.J. Matthews, M. Medecilo & J.R. Castillo leg.; 10♂, 10♀, Gandara, Samar, 12°00'56"N 124°47'43"E, 2.xii.2012, ex A. macrorrhizos, P.J. Matthews, M. Medecilo & J.R. Castillo leg.; 7♂, 9♀, Tanuan, N. Leyte, 11°07'03"N 125°00'55"E, 3.xii.2012, ex A. macrorrhizos, P.J. Matthews, M. Medecilo & J.R. Castillo leg.; 10♂, 10♀, Sabang, Palawan, 10°11'24"N 118°54'00"E, 5.ii.2013, ex A. macrorrhizos, P.J. Matthews, E.M. Agoo & D.A. Madulid leg. (MPMP, SEHU).
Distribution. Borneo (Sabah), Philippines (Luzon, Samar, Leyte, Palawan).
Remarks. This species resembles C. sulawesiana in the apical, vertical dilation of phallal sheath (Figs 20D, 22D), but can be distinguished from it by other diagnostic characters and the oviscapt shorter than the phallus (apodeme + sheath).
Etymology. Referring to the type locality.
