Nephelomilta diehli Volynkin & Černý   , sp. nov.

( Figs.82, 83 View FIGURES 71–83 , 125 View FIGURES 123–125 )

Type material. Holotype ( Figs. 82 View FIGURES 71–83 , 125 View FIGURES 123–125 ): ♂, “ Indonesia, N Sumatra, 15 km NE Prapat, HW 4, 1150 m, 3–6.I.1994, leg. K. Černý”, slide AV2663 ♂ Volynkin (Coll. MWM/ ZSM, ex coll. CKC).

Paratypes: 1 ♂, same data as in the holotype (Coll. CKC); 1 ♂, Indonesia, N Sumatra, 15 km NE Sipirok, 1350 m, Lake Marsabut, 8.I.1994, slide AV2662 ♂ Volynkin (Coll. CKC); 1 ♂, Indonesia, Sumatra, Holzweg 3, 1987, leg. Diehl (Coll. CKC); 2 ♂, N Sumatra, C Samosir, Toba lake, Partunghoan, 2.37 N 98.44 E, 1600 m, 20.IX.1991, secondary forest, leg. Graul & Schintlmeister [in German], slides AV4144 ♂, AV4145 ♂ Volynkin (Coll. CKC).

Diagnosis. Length of forewing is 10–11.5 mm in males. The new species differs clearly from other congeners in its unusual ochreous-yellow body and wing coloration. The male genitalia are most similar to those of N. ferruginea   sp. nov., but can be distinguished in the narrower valve, the more developed medial costal angle, the significantly larger apical costal lobe, the narrower ventral costal plate, the significantly longer, trigonal ampulla (whereas in N. diehli   sp. nov. the ampulla is short, lobe-like, with two small dens on its ventral surface), the slightly shorter subapical saccular process, the significantly shorter and broader aedeagus, the smaller and more weakly sclerotized carinal plate, the presence of the extremely large subbasal diverticulum, the much broader medial and distal diverticula of the vesica, and the much more numerous and robust spines on the distal diverticulum.

The female is unknown.

Distribution. Endemic to Sumatra Island ( Indonesia).

Etymology. The species name is dedicated to memory of Dr. Eduard W. Diehl, a famous collector of insects in Sumatra.
