Parasesarma liho Koller, Liu & Schubart, 2010 and P. cognatum Rahayu
& Li, 2013 from East and Southeast Asia are similar species that
have been confused in several studies. Here, we re-examined the type
specimens of both species and found identical main characters, which is
supported by the molecular identity of the mitochondrial cytochrome
oxidase subunit I gene. As a result, we treat P. cognatum as a junior subjective synonym of P. liho. We also show that the male paratype of P. paucitorum Rahayu & Ng, 2009 is conspecific with P. liho, although P. paucitorum s. str. remains a distinct but allied species. The distribution of P. liho is updated to include Japan (Ryukyus), Taiwan, Philippines (Cebu) and Indonesia (Sulawesi).
Key words: Parasesarma, P. liho, P. cognatum, P. paucitorum, Morphology, Mitochondrial COI.
