Material examined. 1 female (KB.17.113), Brunei Darussalam, Ulu Temburong National Park, Kuala Belalong Field Studies Centre along Ashton Trail, primary ridge dipterocarp forest, N4.54646, E115.15693, 135.2± 6.9 m.a.s.l., under foliage of tree, 29 July 2017, 1853 hours, coll. 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).
