3) Colocasiomyia vieti Toda View in CoL , sp. nov.
( Figs 9F View FIGURE 9 , 15C View FIGURE 15 , 18 View FIGURE 18 )
Colocasiomyia sp.2 aff. diconica: Sultana et al., 2006: 694 .
Diagnosis. Male abdominal sternite VI with a pair of long processes nearly straight and divergent ( Fig. 9F View FIGURE 9 ).
Description (♂ and ♀; not repeating characters common to C. grandis sp. nov.). Head. Supracervical setae 4–6 per side.
Thorax. Anterior dorsocentral setae behind transverse suture. Prescutellar acrostichal setae absent; acrostichal setulae in 2 or 4 rows. Apical scutellar setae slightly more distant to each other than to basal scutellar seta.
Legs. Patch covered with only minute pubescence absent on anterodorsal portion of fore tarsomere I.
Abdomen. Male: sternites III and IV wider than long. Female: sternites III–V longer than wide; VI as wide as long, posteriorly dilated, medially notched on posterior margin.
Male terminalia. Epandrium pubescent except for narrow anterior to ventral margin and anteroventral elongation, roundish on posteroventral margin ( Fig. 18A View FIGURE 18 ). Surstylus long, moderately broad plate with 5–6 recurved teeth apically and 1 trichoid seta ventrosubapically ( Fig. 18A View FIGURE 18 ). Median piece of subepandrial sclerite medially and anteriorly bilobed into long lobes. Cercus pubescent except for anterior margin and apical portion, slightly constricted ventrosubapically, with 34–36 setae all over and small setae on apicoventral margin ( Fig. 18A View FIGURE 18 ). Phallal sheath apically broadly round in lateral view ( Fig. 18B View FIGURE 18 ).
Female terminalia. Oviscapt with 16–18 ovisensilla ( Fig. 18D View FIGURE 18 ).
Indices (range of holotype and 3♂ and 3♀ paratypes): FW/HW = 0.54–0.57, ch/o = 0.43–0.56, prorb = 0.86– 1.03, rcorb = 0.44–0.52, vb = 0.34–0.47, dcl = 0.50–0.73, sctl = 0.65–0.83, sterno = 0.58–0.78, orbito = 0.64–0.89, dcp = 0.63–0.94, sctlp = 0.62–0.95, C = 2.08–2.39, 4c = 0.89–1.04, 4v = 1.46–1.70, 5x = 0.90–1.13, ac = 2.81–3.14, M = 0.36–0.47.
Puparium (3rd instar larva). Anterior spiracle with stalk ending in a whorl of 9–11 branches; stalk longer than longest branch; caudal segments elongate, ending in Y-shaped posterior spiracles ( Fig. 18E–G View FIGURE 18 ). Mouth hook: distal blade as long as basal portion, apically pointed, gently curved downward, with small, acute teeth ( Fig. 18H View FIGURE 18 ).
Holotype. ♂ ( SEHU), “ Cuc Phuong , Nho Quan District, Vietnam, 2.iv.2000, ex Alocasia atropurpurea, M. Yafuso ”.
Paratypes. Vietnam: 3♂, 3♀, same data as the holotype ( SEHU) .
Distribution. Vietnam.
Remarks. This species resembles C. grandis sp. nov. in many characters, but can be distinguished from it by the diagnostic character and the absence of patch covered with only minute pubescence on anterodorsal portion of fore tarsomere I.
Etymology. Patronym, dedicated to Dr. B. T. Viet who helped MY with field work in Vietnam.
