Holotype – ♂ , Thailand : Surat Thani Prov. , 40 km WSW of Phanom Town, environs of Khao Sok National Park, primary/secondary forest, 20–29.VII 1996 , A. Gorochov ( ZIN ). Paratype – same data as for holotype, ♀ ( ZIN ) . DESCRIPTION. Male . Body more or less similar to that of L . ( L .) inaculeata , but with following differences: size slightly smaller; coloration light brown with reddish tinge on anterior surface of epicranium, brown lower borders of antennal cavities and stripe along clypeal suture, dark brown most part of mandible and dorsal spot on fore tibia near distal parts of tympana, darkened small apical parts of femora as well as small basal and apical parts of tibiae, yellowish rest of mouthparts and most part of tegminal venation as well as pleurites and rest of body venter (except for genital plate), greyish brown membranes between tegminal venation, and light greyish brown venation in distal portion of area between R and anal edge of tegmen (Figs 51, 52); structure of head, pronotum and legs also similar to that of L. inaculeata , but rostral tubercle with small distinct (yellowish) lateral ocelli in proximal half, and pronotum with much shorter hind lobe not reaching tegminal mirror (Fig. 52); tegmina moderately long and rather narrow, reaching apex of abdomen and having more or less narrowly rounded apical parts (Fig. 52); last tergite with slightly sinuate posterior edge in dorsal view ( Fig. 47 ); epiproct approximately as in L. inaculeata ; paraproct small and simple, almost without apical tubercle; cercus similar to that of this species, but dorsoapical lobule less widened and with distinct denticle at apex, and ventroapical lobule with two apical spinules (dorsal spinule somewhat shorter than ventral one; Figs 44, 47–49 ); genital plate with rather deep posteromedian notch ( Fig. 48 ); genital median sclerite cruciform, with distal portions widely and obliquely diverging as well as having rather large apical inflations (these inflations with small denticles), and with proximal portions semisclerotized and fused with each other near middle of sclerite at very short distance as well as directed laterally and somewhat forwards; additional semisclerotized lobes near middle or subapical parts of genital sclerite (characteristic of Liara s. str. ) undeveloped ( Fig. 50 ). Female . General appearance as in male, but body larger (approximately as in L. inaculeata ), space between lower edges of antennal cavities with very small brown mark, brown stripe along clypeal suture interrupted at middle, antennal flagellum almost brown in middle and distal parts, pronotum with slightly shorter hind lobe, tegmina reaching middle part of ninth abdominal tergite and with somewhat less contrast coloration, last tergite and epiproct as well as paraprocts and cerci almost as in female of L. inaculeata ; genital plate also similar to that of this species but with clearly wider apical part and posteromedian notch ( Fig. 45 ); ovipositor relatively shorter than in this species and in L. bifurcata ( Fig. 46 ). MEASUREMENTS. Length (in mm). Body: ♂ 27, ♀ 37; pronotum: ♂ 7.2, ♀ 9.3; tegmina: ♂ 17.5, ♀ 21; hind femora: ♂ 15, ♀ 21; ovipositor 13.5. COMPARISON. The new species is most similar to L. ( U. ) harmandi (Brongniart, 1897) in the length of tegmina but distinguished from the latter by the male genital plate with apex deeply notched (but not truncate). From the other representatives of this subgenus, L. ( U .) clavata differs in the longer or shorter tegmina, in the cercal ventroapical lobule of male having two (not one) apical spinules, in the male genital sclerite more similar to that of some species of Pseudosubria Ingrisch, 1998 (convergence) than to that of these congeners, or in the ovipositor relatively shorter.
