Female. Unknown. Figures 1. Male habitus of Lathrobium spp., A Lathrobium lingae B Lathrobium longwangshanense C Lathrobium tianmushanense . Scales: 1.0 mm. Distribution. East China (Zhejiang: Longwangshan Mountain). Etymology. The species is named after Rui-Fen Ling, who collected the type specimens. Remarks. The new species is close to Lathrobium fengae in similar general form. Lathrobium lingae differs especially by the male sternite VII with deeper impression, male sternite VIII with regularly triangular apico-median emargination, and aedeagus with gracile ventral process and single dorsal sclerite. Lathrobium fengae has the male sternite VII with shallower impression, male sternite VIII with irregular apico-median emargination, and aedeagus with broad ventral process and two dorsal sclerites.
