M. K. Tan (dried pinned, ZRC ). Female description. Similar to male in habitus ( Fig. 3A ). Tenth abdominal tergite with posterior margin concave in the middle. Epiproct small and triangular. Cercus slender at the base, swollen in the middle before tapering to a subacute apex; curved at the base, generally straight thereafter ( Figs. 3B, 3C ). Subgenital plate short, small, and transverse, much wider than long; with posterior margin feebly concave broadly ( Fig. 3C ). Ovipositor long; with base slightly swollen, wider than in the middle; with middle third narrow (when viewed in profile), dorsal and ventral margins parallel; with apical third wider than middle third, tapering to an acute apex; feebly sinuated ( Fig. 3C ). Dorsal valve at apex smooth; ventral valve distinctly longer than dorsal valve, finely denticulated along margin near apex; ventral valve forming a small hook at the apex, apex pointing ventrad ( Fig. 3D ). Colouration. Similar to male. Measurement (in mm). BL = 8.8, BWL = 19.2, PL = 3.6, TL = 17.4, HWT = 1.3, HFL = 8.8, HTL = 10.7, OL = 4.8. Comparison. The female differs from congeners by the combination of ovipositor with ventral valve distinctly longer than dorsal valve, forming a small hook at the apex and subgenital plate small and transverse; from subcongeners with known females: L. pulchra Gorochov, 2008 from Mount Trus Madi, Borneo (with ventral valve shorter, without hook instead); and L. sharovi Gorochov, 1993 from Vietnam (with ventral valve shorter, with hook instead). It also differs from congeners with unknown subgeneric status (owing to unknown males): L. capreola (Redtenbacher, 1891) from Java (with ventral valve shorter without hook instead); L. cemande Gorochov, 2008 from Java (with subgenital plate longer than wide instead); L. gialai Gorochov, 2008 from Vietnam (with subgenital plate sophisticated instead); L. martynovi Gorochov, 1998 from Vietnam (with ventral valve shorter, and more strongly curved apically instead); L. raoani Gorochov, 2008 from Vietnam (with ventral valve shorter, without hook; subgenital plate elongated with subacute apex instead); and L. uniformis Gorochov, 2008 from Mount Trus Madi, Borneo (with ventral valve without hook; subgenital plate with posterior margin truncated, with triangular posterolateral corners instead).
