MATERIAL. Holotype – ♀, Malaysia: Borneo I., Sabah State, southern part of Kinabalu

National Park, 1500–2000 m, at light, 26.IV–1. V.2013, A. Gorochov, M. Berezin, V. Gorochova, E. Tkatsheva ( ZIN).

DESCRIPTION. Female (holotype). General appearance similar to that of B. atromacula

sp. n. but with following characteristic features: body uniformly yellowish but with light greyish brown eyes as well as poorly distinct and very light brown stripe on tegmina along anal edges; upper rostral tubercle with more or less truncate apex and more distinct median concavity on dorsal surface ( Fig. 84 ); pronotum slightly lower than in this species, almost 3.1

times as long as high; spine of fore coxa about 0.25 mm in length; tegmina reaching apical parts of hind tibiae; hind wings completely covered with tegmina (distal parts of tegmina,

projected behind apices of hind wings, almost 0.4 mm in length); genital plate strongly transverse, with posteromedian notch very short, rounded and moderately wide ( Fig. 68 );

ovipositor rather long, gradually narrowing to apex, with several denticles on dorsal edge of distal portion of each upper valve and on ventral edge of same portion of each lower valve

(including small apical hook on this valve; Fig. 85 ).

Male unknown.

MEASUREMENTS. Length (in mm). Body 9; body with wings 17; pronotum 3.6;

tegmina 13.5; hind femora 7.5; ovipositor 5.7.

COMPARISON. The new species is distinguished from all the other congeners by the humeral notches of the pronotum less distinct (low and rounded, i.e. almost as in

Borneratura species; but in the other species of Odonturisca , these notches are somewhat deeper and obtuse-angled). Additionally it differs from O. grigoriji by the female genital plate clearly more transverse as well as with the rather widely, shortly and roundly notched posterior part (vs. this part has a narrowly angular but very small apical notch); from O.

serricauda, by the much less deeply notched female genital plate; but additional differences between O. dentata sp. n. and O.? epiproctalis (its female is unknown) are unclear.

ETYMOLOGY. This species name is the Latin word “dentata” (with teeth) due to the ovipositor denticulate.
