Palpus yellow, silver pruinose at tip; abruptly enlarged towards apex. Vibrissa long. Thorax. Scutum grey dusted, with 5 brown fine vittae, the two along the dorsocentral rows of setae reaching the subbasal pair of scutellar setae. Dorsocentrals 1+4, only the posterior pair long. Haltere yellow. Calypters white. Legs. Mostly brown, white grey pollinose; tip of femora yellow; tarsi brown on dorsal surface, yellow on posterior margin of each tarsomere and yellow on ventral surface.

Remarks. Easily identified with the key by Vikhrev (2011a) to the Palaearctic species of the tentaculata -group (see comments on this group under L. consanguinea ). Hennig (1960, text-figs 113, 128, 157, plate 19 fig. 372, plate 20 fig. 391) illustrated the male and female terminalia, and the male terminalia were also illustrated by Vikhrev (2011a, figs 3.3–4, 5.2). Recently recorded from Malaysia by Chew et al. (2012).
