Revision of the genus Stenichnaphes Franz in New Zealand
(Coleoptera: Staphylinidae: Scydmaeninae)

Three species of Stenichnaphes Franz were described from New Zealand: St. urbanus Franz (type species of the genus),
St. peloriensis Franz and St. newtoni Franz, but the two former names were later synonymized. Basing on detailed morphological study, St. peloriensis is reinstated as a separate species, and St. newtoni is transferred to Scydmaenilla King,
within Zeanilla subg. n., resulting in Scydmaenilla (Zeanilla) newtoni comb. n. All three species are redescribed, a previously unknown aedeagus of St. peloriensis is illustrated, and details of morphological structures of St. urbanus and Sc.
newtoni are presented.

The cyrtoscydmine genus Stenichnaphes Franz, 1980a currently comprises 6 species: St. urbanus Franz, 1980a, St.
newtoni Franz, 1986a (New Zealand), St. madagassicus Franz, 1986b, St. similis Franz, 1986b and St. sakarahanus
Franz, 1986b (Madagascar), and St. brasiliensis (Franz, 1967) (Brazil). There were also three other species names
originally published in combination with Stenichnaphes: St. peloriensis Franz, 1986a (New Zealand) was
synonymized with St. urbanus by Kuschel (1990) and St. sumatrensis Franz, 1984 (Sumatra) and St. ceylonensis
Franz, 1982 (Sri Lanka) were placed in a separate subgenus Parastenichnaphes Franz, 1984, which was later
elevated to the genus rank (Franz 1989). Franz (1980a) compared Stenichnaphes to Neuraphes Thomson, 1859 and
Stenichnus Thomson, 1859, genera distributed in the northern hemisphere, and later included Stenichnaphes in an
informal complex of genera comprising also Neotropical Alloraphes Franz, 1980b and Oriental
Parastenichnaphes. His identification key to these three genera included only male genital characters (Franz 1989),
and only recent revisions of Oriental species of Parastenichnaphes and a comprehensive revision of Alloraphes
shed more light on other morphological structures (Jałoszyński 2005, 2013a). The two latter genera show
similarities to Austral Austrostenichnus Franz 1971, Zeanichnus Jałoszyński, 2013b, Scydmaenilla King, 1864 and
Palaeoscydmaenus Franz, 1975, whose morphological structures were recently illustrated and described in detail
(Jałoszyński 2012a, 2013b). All these taxa share the submentum demarcated laterally by oblique sutures, a
character not known in any other southern hemisphere genus whose structures have been studied so far.
Morphological details of Stenichnaphes, including the submentum, were largely unknown, and therefore close
relationships of this genus with Alloraphes and Parastenichnaphes were merely speculations.
To fill this gap in our knowledge, the present study is focused on species of Stenichnaphes described from New
Zealand, as most relevant to ongoing research on the Scydmaeninae of Australia and adjacent areas. Neotropical
and Madagascan species will be treated separately.
