Nephelomilta ranau Volynkin & Černý , sp. nov.

( Figs. 40–42 View FIGURES 37–49 , 102, 103 View FIGURES 102–104 , 135 View FIGURES 134–141 )

Type material. Holotype ( Figs. 40 View FIGURES 37–49 , 102 View FIGURES 102–104 ): ♂, “ Indonesia, Sumatra, South Sumatra, 900 m, Lake Ranau, Tebah Hemi, 4°65’03’’S, 103°57’15’’E, 18.XI.2003, leg. Černý”, slide AV4151 ♂ Volynkin (Coll. MWM/ ZSM, ex coll. CKC).

Paratypes: 1 ♂, 1 ♀, same data as in the holotype, slides AV4147 ♂ Volynkin (coll. CKC); 1 ♂, Indonesia, Sumatra, Bandar Lampung, Bukit Rigis Mts., Gunung Terang, 1 0 22 m, 5°3’43’’S, 104°27’6’’E, 13–15.XI.2003, leg. Černý, slide AV4153 ♂ Volynkin (coll. CKC); 1 ♀, Indonesia, N Sumatra, Huta Padang, 175 m, 10.VIII.1989, leg. E. Diehl, slide AV2346 ♀ Volynkin (Coll. NHMUK, ex coll. CKC).

Diagnosis. Length of forewing is 9.5–10 mm in males and 10.5–11.5 mm in females. The new species is a closest relative of N. klapperichi , from which it differs externally in its ochreous-yellow thorax and forewing pattern. The male genitalia of N. ranau sp. nov. differ from those of N. klapperichi in the more developed medial costal angle, the significantly larger apical costal lobe, the significantly larger ventral-apical costal process, the slightly larger subapical saccular process, the slightly narrower distal diverticulum of the vesica with smaller cluster of small cornuti, and the significantly narrower medial diverticulum with smaller spines on its tip. The female genitalia of N. ranau sp. nov. differ from those of N. klapperichi in the narrower, trigonal ventral processes of subostial lobes, the significantly smaller spinules in the appendix bursae and the posterior section of the corpus bursae, and the stronger setose scobination around the signum.

Distribution. Endemic of Sumatra Island ( Indonesia).

Etymology. The species’ name refers to its type locality, Lake Ranau in South Sumatra.
