D e s c r i p t i o n: 2.3 mm. Habitus as in Fig. 68. Based on external characters (Figs 69-70) indistinguishable from L. curvata (see preceding section), so that a detailed description is here refrained from. Both species are reliably separated only by the morphology of the aedeagus.

3: tergite and sternite VIII as in Figs 71-72; median lobe of aedeagus of similar general morphology as in L. curvata , but ventral process straight at base and in the middle distinctly angled (Fig. 73); apical lobe of paramere as in L. curvata .

♀: unknown

E t y m o l o g y: The name (Lat., adj.) refers to the uncurved base of the ventral process of the aedeagus (lateral view), a character distinguishing this species from the extremely similar L. curvata .

C o m p a r a t i v e n o t e s Fordistinctionfrom L. curvata , the only similar Chinese representative of the genus, see the description above. For remarks regarding the subgeneric placement of the species see the comparative notes in the section on L. curvata .
