In order to stabilise the nomenclature, the syntypespecimen deposited in the type collection of the OUMNHis hereby designated as the lectotype. (2)The male genitalia of the species slightly vary in the length of the dorsal part of the valva and the distal saccular process as well.   Diagnosis. The forewing length is 13.5–15.5 mmin males and 15.0– 17.5 mmin females. The male genitalia structure of  L. leucanioidesis most similar to  L. diehliand the detailed comparison is provided below under the diagnosis of this species.   Distribution. The species is reliably known from Malaysia(Borneo Island and Malay Peninsula) ( Holloway 2001; Bucsek 2012), Singapore, Thailand( Černý & Pinratana 2009, partim.), Cambodia, Vietnamand central and southern Laos. The records from northern Laos( Kishida 2020), southern Myanmar( Hampson 1900; Holloway 2001) and south-western China( Yunnan) ( Fang 2000) require clarification and may belong to  L. witti. The record from Sumatra ( Holloway 2001) belongs to either  L. diehlior  L. inusitataor  L. lampunga. The records from the Philippineswithout islands being specified ( Bucsek 2012; Kishida 2020) belong to either  L. leptivalvaor one of the three species of  Philippinithosia. The records from Java ( Bucsek 2012) and Xizang, China( Fang 2000) require further clarification as no material available was found during the current study. 4423362339 1996-03 1996-04-31 1996-03 ZSM Malaysia 950 5.4333334 Mt.
