Rhinoteratura uniformis (Gorochov, 2008) , comb. n.

Figs 56–58 , 69–74

MATERIAL. Malaysia: 2 ♂, 1 ♀, Borneo I., Sabah State, Crocker Range National Park ,

at light, 15–26.III.2018, M. Omelko ( ZIN) .

DESCRIPTION. Male (nov.). Coloration and structure of body very similar to those of holotype (female) of this species: body light greenish with light brown to almost rose eyes,

yellowish areas on epicranium behind eyes and a pair of stripes along lateral edges of disc,

transparent stridulatory areas of tegmina and very light brown stripe along each tegminal anal edge behind stridulatory apparatus; head opistognathous; upper rostral tubercle dorsoventrally lamellar and gradually narrowing to almost narrowly rounded apex (this apex barely wider than in holotype, as in Fig. 69 ); eyes large, strongly comvex, longitudinally oval; epicranium with anterior surface under upper rostral tubercle transversally concave but with distinct transverse convexity under this concavity; apical segment of maxillary palpus hardly shorter than subapical one; pronotum with more or less flat disc which somewhat wider than height of lateral lobes and with almost keel-like lateral edges; lateral lobes of pronotum as in Fig. 70 ; spine of fore coxa about 0.3 mm in length; tegmina approximately reaching apical parts of hind tibiae; exposed parts of hind wings, visible behind tegminal apices, about 0.5–1 mm in length; last tergite rather large and convex, with slightly but almost angularly notched posterior edge; epiproct small (short), lobe-like, semimembranous, directed downwards; paraprocts more or less similar to it in size and shape; cercus not long and somewhat curved medially as well as having a pair of distal lobes (dorsolateral lobe elongate,

slightly widened, almost lamellar, located in vertical plane, and with small dorsal subapical notch and longer subbasal concavity of ventral edge; ventromedial lobe somewhat smaller,

more simple in shape and not lamellar) and two small inner tubercles at base of these lobes and before this base ( Figs 57 , 71–73 ); genital plate oval, with moderately narrow apical part having a pair of small angular lobules (styles fused with this plate) and convex posterior edge between them ( Fig. 58 ); genitalia membranous.

Female. Above-mentioned female almost identical to holotype, but its rostrum as in males ( Fig. 69 ), and genital plate with slightly longer posteromedian (angular) projection

( Fig. 56 ); ovipositor apex in both females with very narrowly rounded (almost acute angular)

apices of all valves ( Fig. 74 ), i.e. without denticles or apical hooks (almost as in Fig. 63 ).

MEASUREMENTS. Length (in mm). Body: ♂ 9–9.5, ♀ 9.2; body with wings: ♂ 18–19,

♀ 20.5; pronotum: ♂ 3.2–3.3, ♀ 3.3; tegmina: ♂ 15–15.5, ♀ 16.5; hind femora: ♂ 7–7.3, ♀

7.8; ovipositor 4.7.

REMARKS. These specimens are collected in another mountain range than the type material (two females) from Trus Madi Mont situated not far from this range. Thus, R .

uniformis is here recorded from another locality. However, it is possible that the abovementioned specimens belong to another subspecies, because the genital plate of their female is with a slightly longer posteromedian projection (in the females from Trus Madi Mt, this projection is slightly shorter, or this plate is almost truncated posteriorly; Gorochov, 2008).
