Henicops Newport, 1845

Type species: Henicops maculatus Newport, 1845 ; by original designation.

Diagnosis: Member of Lamyctes­Henicops group with 26–51 antennal articles; dental margin of maxillipede coxosternum with 3+3 or 4+4 teeth (exceptionally up to 6+6), lacking pseudoporodont; laciniate or plumose setae amidst simple setae on coxal process of first maxilla; projections on (at least) tergites 9, 11 and 13; last distal spinose projection of tibia on leg 14; tarsi of legs 13 and 14 divided into three or four tarsomeres; distitarsus of leg 15 divided into at least two tarsomeres; first genital sternite of male divided longitudinally into two sclerites.

Discussion: The diagnosis of Henicops above accounts for two characters of H. washpoolensis that differ from previously described species and had been cited in early generic diagnoses ( Pocock 1901; Attems 1928; Archey 1937). These characters are the presence of more than 3+3 teeth on the maxillipede dental margin, and the bipartite (rather than tripartite) tarsi on legs 1–12 (also bipartite in H. howensis Edgecombe, 2004 ). Some specimens of H. washpoolensis share the 3+3 dentition with other Henicops , and the subdivision of the basitarsus of legs 1–12 is marked by the position of thickened setae, though not by an articulation. The phylogenetic analysis discussed below indicates that H. washpoolensis is either nested within Henicops as conventionally delimited (e.g., Attems 1911, 1914, 1928; Archey 1917, 1937) or is sister group to that clade, and the diagnosis is accordingly modified.
