Amynthas corticis (Kinberg, 1867)

[ Fig. 2 ]

Material examined. IV0000261258, a representative mature specimen from Tongumi (figured); other specimens not kept.

Description. 110 mm long with marking in 7-8-9lhs only and spermathecae in 5/6-8/9, i.e., one side complying with “ A. heteropodus ”, one side not. Otherwise agreeing with A. corticis .

Remarks. Part of a cosmopolitan Amynthas corticis species-complex sensu Blakemore (2002; 2010b; 2012d) wherein it is fully described with its many synonyms including Perichaeta heteropoda Goto & Hatai, 1898 that is still quoted as a valid taxon from Korea by Hong & Kim (2005) and Hong & James (2009: 1255). Amynthas sangumburi Hong & Kim, 2002 is a probable new synonym ( Blakemore 2013), provisionally retained as herein pending further research by its original author (Y. Hong pers. comm.).
