Ctenocheles Kishinouye, 1926

Ctenocheles Kishinouye, 1926: 36 .—de Saint Laurent, 1973: 514.— Poore and Griffin, 1979: 277.—de Saint Laurent and Le Loeuff, 1979: 81–83.— Sakai, 1999c: 88.— Sakai, 2005b: 237–238.— Sakai, 2011: 486–487 (key to species).—Hyžný et al., 2014: 249–250.— Poore and Dworschak, 2017: 122 (synonymy).

Tosacallianassa Sakai and Türkay, 2016: 813 (type species, Tosacallianassa hatasagaensis Sakai and Türkay, 2016 , by original designation and monotypy).

Type species. Ctenocheles balssi Kishinouye, 1926 , by monotypy.

Diagnosis. Cardiac prominence present. Rostrum blade-like, produced anteriorly. Male major cheliped merus with oblique spine near midpoint of lower margin (or absent); propodus swollen, with fine pectinate fingers at least twice as long as palm. Minor cheliped merus lower margin smooth, or with spine at or near midpoint; propodus cylindrical, slightly swollen at midpoint, about twice as wide as long. Male pleopod 1 article 2 simple, tapering, without coupling hooks. Telson parallel-sided over anterior half, then tapering to evenly rounded apex.

Remarks. The blade-like rostrum combined with the fine long pectinate fingers of the major cheliped of Ctenocheles make its species easily recognisable. In fact, some species are known only from these claws ( Holthuis, 1967; de Saint Laurent, 1979a). To the six described species listed by Sakai (2005b, 2011) can be added C. plantei ( Burukovsky, 2005) , described as a member of the lobster genus Thaumastochelopsis Bruce, 1988 ( Poore and Dworschak, 2017).
