Descriptive notes.

Male. Aedeagus: basal piece nearly as long as dorsal plate of each paramere (Fig. 3A-C ); ventral process of each paramere stout and abruptly narrowed near apex, obviously bent inwards in ventral view (Fig. 3A ), slightly bent dorsally in lateral view (Fig. 3C ); dorsal plates of parameres obviously longer than ventral processes, with lateral margins slightly sinuate in middle, apical margins slightly arcuate and descending outwards in lateral view (Fig. 3B ); laterophyse feebly shorter than ventral process, with apex acute and directing dorso-outwards (Fig. 3A ); inner sac of median lobe with a stout tube extruding near base (Fig. 3A, B ).

Female. Internal organ of reproductive system (Fig. 12C ): spermatheca nearly as long as diverticulum; accessory gland ~ 2.5 × longer than spermatheca.

Abdominal sternite VIII (Fig. 16C ): triangular emarginations on both sides and in middle of posterior margin, lateral emarginations slightly deeper and much wider than the middle one, the portions between lateral and middle emarginations wide and obtuse-triangular at apices, slightly extending over apices of latero-apical angles, which are nearly truncated.

Distribution.

China (Yunnan).

Remarks.

Cantharis jeanvoinei Pic, 1927 was listed as a synonym of L. guerryi by Kazantsev and Brancucci (2007), which is an obvious error. In fact, the former was synonymized with L. guerryi atroapicipennis (Pic, 1914) by Wittmer (1995), but was missing in the Palaearctic Catalogue ( Kazantsev and Brancucci 2007).
