Description
Worker
Seifert (2020) - Related to Lasius sichuense and Lasius coloratus. Smaller (CS 921 µm). Head length comparably large, scape length index smaller than in the other two species (CL/CW900 1.093, SL/CS900 0.989). Postocular distance slightly smaller and eye slightly larger (PoOc/CL900 0.241, EYE/CS900 0.245). Torulo-clypeal distance comparably large and terminal segment of maxillary palp shorter (dClAn900 5.04, MP6/CS900 0.178). Number of mandibular dents larger (MaDe900 8.67). Pubescence on clypeus much more dilute (sqPDCL900 5.80); frontal pubescence of medium length (PLF900 28.9). Setae of large to medium length (PnHL/CS900 0.160, GuHL/CS900 0.106) and overall rather numerous; on genae, underside of head and below propodeal spiracle more numerous than in L. sichuense (nGen900 7.6, nGu900 5.7, nSt900 4.9). Overall sculpture in comparison to L. sichuense and L. coloratus reduced and more shining. On dorsum of head a microreticulum is absent, the only elements of microsculpture are a number of very fine and short longitudinal carinulae and the shallow pits forming the bases of pubescence hairs. Sculpture on mesosoma reduced in comparison to sister species and metapleuron with much finer longitudinal carinulae. Lateral pronotum very shining. Scale in frontal view with more straight, dorsad less converging sides and straight or feebly emarginate dorsal crest. Coloration: homogeneously yellowish to chestnut brown.
