– Pro- and meso-outer claws simple in male; aedeagus: conjoint dorsal plate of parameres with rounded lateral angels, ventral process of each paramere normal at base.......................................................... 2

2. Antennae wider in female than in male; aedeagus: conjoint dorsal plate of parameres narrowly emarginated in middle of apical margin, with lateral margins of emargination bent ventrally................ L. nigrigenus sp. nov.
