MATERIAL. 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 similar to that of L. (L.) bifurcata in size and coloration,

however: head and pronotum reddish brown with somewhat lighter lower halves, brown border of antennal cavities and small area between these cavities, and brown to dark brown

(almost black) anterior surfaces of mandibles; tegmina light brown with brown membranes between venation in distal half and in costal area of proximal half ( Figs 11, 12 ); legs and posterior tergites as well as cerci and epiproct reddish brown, but apices of femora and tibiae as well as bases of middle and hind tibiae somewhat darkened, and proximal part of fore tibiae with dark brown dorsal stripe at base and between tympana; rest of body almost yellowish with reddish tinge on tergites, posterior sternites and genital plate. Structure of body also similar to that of L. (L.) bifurcata , but: rostral tubercle almost spinule-like; hind pronotal lobe completely covering tegminal mirror; tegmina strongly protruding beyond pronotum and reaching middle part of forth abdominal tergite, widely rounded at apex ( Figs 11,

12); last tergite with very short and widely truncated posterior lobe ( Fig. 38 ); epiproct simple,

small, more or less triangular; paraproct also small, with very short and rounded tubercle at apex; cerci moderately short and rather thick, with distal part flattened, somewhat curved medially, divided into short but rather large dorsal lobule (this lobule widely rounded and lacking spinules or angular projections) and longer but narrow ventral lobule (latter lobule almost in contact with previous lobule and without distinct denticles at apex; Figs 38–40,

42); genital plate as in Figs 39, 40 ; genitalia with sclerites having distal portions almost straight but with apical parts slightly widened, rounded, denticulate and curved in profile,

and with large (but rather narrow) semisclerotized lateral lobes near middle parts of these sclerites; proximal portions of these sclerites semisclerotized, arcuately curved, directed aside and almost fused with each other at short distance ( Fig. 41 ).

sp. n.; 44–50 – L. (Unalianus) clavata sp. n. Male abdominal apex from above (31, 38, 47),

from below (32, 39, 48) and from side (33, 40, 49); male genital sclerite (sclerites) from above (34, 50) as well as from above and from side (41); female genital plate from below

(35, 43, 45); ovipositor from side (36, 37, 46); left male cercus from behind (42, 44).

Female. General appearance as in male, but area between antennal cavities lighter (light reddish brown), femora practically without darkened areas, pronotum with much shorter hind lobe, tegmina smaller (reaching middle part of second abdominal tergite) and lacking stridulatory apparatus, last tergite with more rounded posterior lobe having small and rounded posteromedian notch, paraprocts without tubercles, and cerci as in female of L.

bifurcata. Genital plate almost triangular but with apical part slightly elongate and having a pair of narrow, long, flat and acute lobules ( Fig. 43 ); ovipositor as in Fig. 37 .

MEASUREMENTS. Length (in mm). Body: ♂ 34, ♀ 33; pronotum: ♂ 11.5, ♀ 9.8; tegmina, visible parts: ♂ 10, ♀ 6.7; hind femora: ♂ 17, ♀ 18.7; ovipositor 17.5.

COMPARISON. The new species is similar to L. (L.) magna Ingrisch, 1990 and more or less to L. (L.) monkra Ingrisch, 1998 in the widely rounded dorsoapical lobule of the male cercus lacking any spinule or distinct angular projection, but it is clearly distinguished from these species by the ventroapical lobule of this cercus not acute and lacking any distinct spinule or denticle at apex, and by the male genital sclerites with somewhat narrower lateral

(subapical) lobes. From the other representatives of this subgenus, L. (L.) inaculeata differs in the dorsal and ventral lobules of male cercus lacking distinct angular projections, spinules or denticles, in the above-mentioned characters of male genital sclerites, and in different shape of male or female genital plates.

ETYMOLOGY. The name of this species is the Latin word “inaculeata” (lacking spinule);

such name is connected with the absence of spinules on the both lobules of male cercus.
