discussion
Remarks This species resembles L. sarawakensis Kimsey, 1988 in having a darker body color, scrobal sulcus, and scape more than twice as long as wide. However, it can be distinguished by the following combination of characteristics: rectangular frontal projection (L. sarawakensis triangular); transverse depression absent behind ocelli (L. sarawakensis with transverse depression).
