Type material.
Holotype ♂ (#03879): MALAYSIA: Poring, Mt. Kinabalu, Sabah, 20.iii.2008, MJ Toda (KPSP).
Paratypes: same data as holotype (1♂, 1♀: #03880, #03881, KIZ; 1♂, SEHU); same data as holotype except for 13.iii.2008 (1♀: #03883, KIZ); same data as holotype except for 19.iii.2008 (1♂, SEHU); same data as holotype except for 3.x.1999 (1♂, SEHU); Mahua, Crocker Range, Sabah, Malaysia, 14.x.1999, MJ Toda (1♀, KPSP; 2♀, SEHU); Ulu Senagang, Crocker Range, Sabah, Malaysia, 18.x.1999, MJ Toda (1♂, 2♀: #03884-3886, ZSM).
Diagnosis.
Wing largely clouded, except for central pale patch around dm-cu vein and periphery (Fig. 3G View Figure 3 ); dorsolateral tentorial apodemes nearly parallel in basal half (Fig. 4H View Figure 4 ); tenth sternite mediolaterally with a pair of round depressions (seen in anterior view; Fig. 6E View Figure 6 ); oviscapt valve 2/5 as broad as long (Fig. 6J View Figure 6 ).
Description.
Head (Figs 3E, F View Figure 3 , 4F-J View Figure 4 ): First flagellomere grayish yellow. Supracervical setae 15-22 per side; postocular setae 17-21 per side. Palpus with one subprominent lateromedial seta. Cibarium with 78-79 medial and ca. 8 posterior sensilla per side.
Wings (Fig. 3G View Figure 3 ): Veins pale brown to dark brown, but pale within central pale patch. Halter pale gray; stem darker.
Legs (Fig. 3E View Figure 3 ) pale grayish yellow; foreleg coxa, tibia and tarsus, except for fifth tarsomere, dark brown. Mid-leg first tarsomere longer than total length of four succeeding tarsomeres; hindleg first tarsomere as long as total length of four succeeding tarsomeres.
Male terminalia (Fig. 6A-I View Figure 6 ): Epandrium pubescent except for anterior portion, with 3-4 dorsal and 9-12 ventral, long setae per side. Surstylus with prensisetae in nearly straight row on caudal margin, 2-4 apically pointed spines but no pubescence on outer surface and ca. 20 apically pointed, recurved spines on inner, caudal portion. Cercus pubescent except for caudal margin, with 6-12 long setae near dorsal to posterior margin and 6-7 short setae in cluster on ventral portion of sclerotized marginal plate. Paramere with sensilla subapically.
Female terminalia (Fig. 6J-L View Figure 6 ): Oviscapt valve with ca. five lateral and 12-14 marginal, peg-like ovisensilla. Introvert of spermathecal capsule 1/5 as deep as capsule height.
