61) Macroteratura (Stenoteratura) twinsloba Liu sp. n.

Holotype ♂ (left hind leg lost): NEPAL: Kathamandu / 1300–1400 m./ 7–12.V.1966; J. & M. Sedlacek / Collectors / BISHOP MUSEUM

Paratype ♂ (left middle, right middle and hind legs lost): same labels as above

Description. Body medium size, fastigium of vertex narrow with distinct middle furrow. Pronotum with metazona as long as prozona, lateral plate with distinct humeral sinus. Wings longer than tegmina, beyond apex of hind femur ( Fig. 28a ). Hind tibia bearing 3 pairs of apical spurs.

Male 10 th tergite with a deep and big posteriomedian notch, bearing 1 pair of long and thick lobes, nearly reach

to the strong bent cerci. Epiproct specialized into a pair of thin lobes under the thick long tergite lobes ( Fig. 28b, c ). Male cerci strongly bent, basal half thick, lateral margin enlarged, each side with a small tooth, apical half narrow with pointed apex. Subgenital plate short with posterior margin even, styli short, distinct ( Fig. 28 c–f).

Female unknown.

Comparison The overall morphology is very similar to Macroteratura (Stenoteratura) yunnanea (Bey-Bienko,1957, Xiphidiopsis ) from Yunnan, China. But the paired lobes of male 10 th tergite is short, specialized epiproct in pairs too, hind tibia with 3 pairs of apical spurs. It closes to Teratura (Stenoteratura) bhutanica Ingrisch, 2002 from Bhutan by general morphology too, though female is unknown yet.

Measurements (mm). Body: ♂ 10.7–11.9; Pronotum: ♂ 4.1–4.3; Tegmina: ♂ 16.5–17.4; Hind femora: ♂ 10.0– 10.1.

Etymology. Name refers to the form of male epiproct specialized in pairs.
