Diagnostic characters. ♂ —Cercus in lateral view: 4/5 basal straight with the apical 1/5 forming almost a right angle, basal spine clearly visible and the semicircular medial expansion visible. Cercus in mediodorsal view: base of cercus with a mesally–directed long spine, medial expansion semicircular with the outer border covered with spines. Paraproct in lateral view: almost the same size of the cercus. Paraproct in dorsal view: long and narrow (less narrow than L. bipupillatus) with a spoon–like tip.

♀ —Basal plate: species belonging to basal plate group 2 (Fig. 38), with dorsal side twice the length of ventral side, dorsal side with anterior 1/4 slight concave and posterior 3/4 convex. The junction of dorsal side with posterior side forming an acute process directed slightly downward. Posterior and ventral sides subequal (Fig. 39B). Pectoral color pattern as Fig. 40F.
