MATERIAL. Holotype – ♂, Malaysia: Borneo I., Sarawak State, Kubah National

Park on Matang Mt near Kuching City, 200–500 m, primary forest, 27.XI–1.XII

2016, A. Gorochov, M. Berezin, E. Tkatsheva, I. Kamskov.

DESCRIPTION. Male (holotype). Size, coloration and structure of body similar to those of L. (L.) a. lambir and L. (L.) a. similajau but with following differences:

head with rostrum and dorsum almost uniformly yellowish; pronotum yellowish with brown anterior margin of disc and interrupted sinuate transverse line on disc near this margin as well as a pair of short oblique lines slightly behind previous (sinuate)

line; fore and middle femora uniformly yellowish; hind femur also uniformly yellowish but with brown apex and a pair of dark brown longitudinal spots on inner and outer surfaces very near this apex (almost as in L. a. alienus ); rest of body yellowish with more or less light brown majority of abdominal tergites and sternites

(in living condition, latter sternites possibly lighter), cercal and paraproctal apices,

cercal proximedial hooks, median part of epiproct, and styles of genital plate, as well as with brown dorsum of last tergite ( Figs 34, 35 ); tegmina with slightly larger loop-like cell behind stridulatory vein and wider apical area as well as somewhat longer (moderately short) stridulatory vein of left tegmen ( Fig. 79 ); last tergite with posteromedian notch as wide as in L. (L.) a. lambir and almost as deep as in L. (L.) a.

similajau; proximedial cercal hook with ventral branch as long as in these subspecies but having barely widened (not narrowed) apical part, and with dorsal lobule intermediate between such lobules of above-mentioned taxa in shape but almost pressed to ventral cercal branch ( Figs 7, 8 ); posteromedian notch of genital plate between styles even deeper than in L. (L.) a. similajau ( Fig. 7 ).

Female unknown.

MEASUREMENTS. Length (in mm). Body 11; pronotum 4.2; tegminal parts visible behind pronotum 0.6; hind femora 11.7.

COMPARISON. The new subspecies differs from the nominotypical one in the male tegmina having the apical area wider, and in the male cercal proximedial hook with a widened apex of its ventral branch and with the dorsal lobule almost pressed to the latter branch. From all the other subspecies of this species, L. (L.) a. kubah is distinguished by the same characters of the male tegmina and cerci, as well as by the stridulatory vein of the left tegmen longer, the loop-like tegminal cell larger, the body coloration lighter and more uniform, the male last tergite with the posteromedian notch wider or deeper, and the male genital plate with the posteromedian notch deeper (see Figs 1, 4 and 7 ).

ETYMOLOGY. The new subspecies is named after Kubah National Park where it was collected.
