Material examined. Holotype (male): Thailand: Lampang, Doi Khun Tan , elev. 900–950 m (18°29'N, 99°18'E), 16–17.ix.1993, leg. S. Ingrisch—(Bonn ZFMK). GoogleMaps
Diagnosis. As in other species of the genus, the male of L. khuntan has the apical area of the ninth abdominal tergite furrowed in midline and somewhat compressed and projecting behind. But in contrast to other species, these projecting areas form two lobes each: a compressed parallel-sided elongate lobe with obtuse tip and a thin, fingershaped, but sinuate ventral lobe. These lobes overlap each other when at rest.
Description. Medium sized species ( Fig. 19F View FIGURE 19 ). Head: Face ovoid, forehead with impressed dots; fastigium verticis distinctly wider than scapus, separated by a fine suture from fastigium frontis; ocelli distinct, median ocellus rather large; subocular furrow shallow. Abdominal tergites two and three each with two rows of stridulatory pegs (5 minute, 8; 8, 13; Fig. 19H View FIGURE 19 ).
Wings surpassing middle of stretched hind tibia. Tegmen: Radius with two branches, both forked near tip; media anterior fused with radius for more than basal third of tegmen; media posterior absent; cubitus anterior dividing into two veins before mid-length of tegmen; cubitus posterior undivided, free throughout; with 4 anal veins, the last vein short, with short common stem with third analis.
Legs: Fore coxa with a spine at fore margin; fore and mid femora unarmed; fore and mid tibiae with four pairs of large ventral spines and one pair of smaller ventral spurs; hind femur with 4 external and 1 internal spines on ventral margins; hind tibia with spaced spines on both dorsal margins, ventral margins with one pre-apical spine; with 3 apical spurs on both sides.
Coloration. General color yellow brown with indistinct pattern; pronotum with dark rim. Face dark red, ocelli and a spot at ventral margin of clypeus yellow, antennae brown, mandibles black, maxillary palpi pale yellow. Tegmen semi-transparent yellow; veins and veinlets light brown; hind wing semi-transparent white to light ochre, veins and cross-veins blackish brown, cells between veinlets dark brown, in center with light oval spot.
Male. Ninth abdominal tergite globular, furrowed in midline, in posterior area with granular surface, swollen on both sides and deeply furrowed in between, swollen areas each terminating into a blunt cone; ventro-apically on both sides of those cones with a long and thin, little sinuate projection with obtuse tip ( Figs. 20 View FIGURE 20 G–H); cones of both sides overlapping each other at tip, while projections crossing each other behind their bases ( Fig. 20G View FIGURE 20 ). Subgenital plate with basal area much wider than long; apical area in middle between bases of styli prolonged and with converging lateral margins (little distorted in specimen at hand), at tip slightly bilobate (recurved in specimen at hand); styli stout, conical, inserted at apico-lateral angles of basal area ( Fig. 20H View FIGURE 20 ).
Female unknown.
Measurements (1 male).—body w/wings: 30.5; body w/o wings: 23.5; pronotum: 4; tegmen: 21.5; tegmen width: 8; hind femur: 12; antenna: 110 mm.
Etymology. The new species is named after the type locality; noun in apposition.
