3 Lateral sclerites of endophallus in dorsal view nearly transverse in relation to long axis of aedeagus............................................................................................... L. minor Jałoszyński [Borneo]

- Lateral sclerites of endophallus in dorsal view strongly oblique in relation to long axis of aedeagus.................... 4

4 Endophallus lacking median sclerotized structure distal to lateral sclerites, but bearing a pair of elongate subtriangular sclerotized lobes proximal to lateral sclerites.............................................. L. chinensis Zhou & Li [Yunnan]

- Endophallus with median sclerotized structure distal to lateral sclerites, and lacking a pair of elongate subtriangular sclerotized lobes proximal to lateral sclerites........................................................................ 5

5 Median sclerotized structure distal to lateral sclerites of endophallus about as long as broad and with concave distal margin; parameres clearly longer than median lobe..................................... L. anaiensis Jałoszyński [Sumatra]

- Median sclerotized structure distal to lateral sclerites of endophallus strongly transverse and with convex or straight distal margin; parameres as long as or shorter than median lobe..................................................... 6

6 Median structure of endophallus distal to lateral lobes weakly sclerotized, its distal margin nearly straight at middle and laterally rapidly bent lateroproximally; aedeagal apex in ventral view broadly subtriangular with clearly defined tip.................................................................................. L. umphangensis Jałoszyński [ Thailand]

- Median structure of endophallus distal to lateral lobes strongly sclerotized, its distal margin evenly or nearly evenly rounded; aedeagal apex in ventral view truncate and weakly, broadly rounded............................................ 7
