Reicheiodes (Himalayodes) ellipsoideus BALKENOHL, 1995

Type material: Holotype, ♀, with label data “404 Sankhua Sabha Distr., above Pahakhola , 2600–2800 m, Quercus semicarpifolia, Rhododendron , 21 May to 3 June 88 MARTENS & SCHAWALLER ”, “ NEPAL Expeditionen Jochen Martens ” ( SMNS).

Additional Material: Nepal, Kosi - Gufa Pokhari 27°17‘N / 87°30’E to Chauki 27°12’N/87°28’E, 2900– 2600 m, 21. VI.2001, 1 ♂, 4 ♀, leg. “ NHMB Basel expedition to Nepal ” (locality code #21b) ( NHMB, CSCHM, CBB).

Supplemented redescription. Ventral surface: No differences observed among sexes.

Male genitalia ( Figs 9, 10 ): Median lobe moderately sclerotized, regularly arcuate in middle part, slightly flattened and distorted in apical half, apex formed by broad asymmetrically rounded spatula, slantwise attached to medial lobe, dorsally and ventrally with some short minute pili in basal half. Oroficium nearly half as long as lobe, closing lips less sclerotized. Endophallus in apical half with bunch of minute bristles (visible in lateral view at 500 times by optimized condenser). Parameres asymmetrical, both somewhat twisted, length of the ventral one a third of the dorsal one; both parameres with two short setae at apex (160 times).

Female genitalia ( Fig. 11 ): Coxostylus conspicuously small, slender, dorso-ventrally flattened, bent in apical half, carinate in apical two thirds, with one long nematiform seta at apex distinctly longer than coxostylus. Ramus securiform.

Variation: In the six specimens investigated, the globosity of the pronotum varies so that the lateral channel is more or less visible dorsally.

The anterior transverse line is more or less expressed as punctured line or broader punctures, and the lateral wrinkles vary from specimen to specimen. On the elytron the posterior one of the two dorsal setigerous punctures is more or less faintly developed (best visible at 120 times onwards), and the basal setigerous puncture is either situated in the projection of the first stria or slightly more approaching the extension of the second interval. In some specimens the coloration at the apex of the elytra is less pale than in the holotype.

Distribution ( Fig. 12 ). Mountains directly to the east of the Arun Valley, East Nepal: Milke Danda, Jaljale Himal.

Habitat. Unknown.
