Lipotactes undetermined

Lipotactes sp. (Fig. 8) Material examined. EAST MALAYSIA, Sabah, Sandakan, Sepilok, Rainforest Discovery Centre • 1♀; N5.87383 E117.94169, 49.4± 5.9 m.a.s.l.; 2 October 2019, 20h00, on foliage; coll. M.K. Tan, M. Binti, J.L. Yukang; SDK.19.93 (ZRC. ENT74311) • 1♀ (Fig. 8A); N5.87562 E117.93951, 57.2± 5.5 m.a.s.l.; 19 May 2022, 21h33, on foliage of small tree; coll. M.K. Tan & T. Robillard; SBH.22.168 (ZRC). Remarks. Our female specimens from Sandakan are very similar to the holotype of Mortoniellus chopardi Zeuner, 1936 (synonym of Mortoniellus karnyi Griffini, 1909) from Peninsular Malaysia in the dark colour patterns, although there are also some differences: pronotal disc with black band along anterior and posterior margins broad and clearly defined (instead of narrow and vaguely defined, respectively); fore and middle femora black except basal third (instead of completely pale coloured), hind femora at apical half black with a pale green ring near knee (instead of mostly pale coloured). The female subgenital plate appears to be rather variable, even between intrapopulation individuals (Figs 8B, 8C). Without male specimens, it is not clear whether our specimens from Sandakan represent a distinct species.
