Key to the Antrokoreana species based on adult males The following key is based mainly on Murakami (1969) and incorporates Shinohara (1973) but excludes A. gujoensis described by Masuda (2010). The precise key of Antrokoreana species is hampered by the lack of detailed morphological features of A. gujoensis, and therefore its taxonomic account should be revisited by a future study. 1 Anterior margin of anterior gonopods convex; posterior gonopods arcuate. A. arcuata - Anterior margin of anterior gonopods nearly straight; posterior gonopods straight or slightly bent. 2 2 Telopodites of anterior gonopods 2 articulate. 3 - Telopodites of anterior gonopods single articulate. 4 3 Coxae of leg-pair 2 with many recurved setae. A. uenoi - Posterior surface of leg-pair 2 coxae asetose. 5 4 Apex of posterior gonopods with uncinated process, with fine seta at middle of inner margin. A. uncinata - Posterior gonopods without uncinated process or fine seta. 6 5 Body length of mature individuals exceeding 20 mm; coxal processes of anterior gonopods usually with several basal spinules. A. gracilipes - Body length of mature individuals less than 20 mm; coxal processes of anterior gonopods without basal spinule. A. gamooi 6 Distal part of anterior gonopods rounded. A. takakuwai - Distal part of anterior gonopods concave. A. asuwaensis sp. nov.
