Kanozata Matsumura

Kanozata Matsumura, 1940: 67 .

Type species: K. arisana Matsumura 1940 , by original designation.

Remarks. Previously this genus was known only from its type species, but three other species are tentatively included here. Two of these, K. contermina (Distant) and K. shillongana (Distant) , were originally described in Aufidus, a genus characterized by its sulcate fore tibia which is lacking in these two species. Based on the absence of the sulcus on the fore tibia Lallemand (1949) questioned the placement of shillonganus and Chou et al. (1988) transferred it to Stenaulophrys . Despite the differences between arisana and the other three species (see key) all have similar male genitalia (figures 1, 2) with an elongate pygofer, strongly recurved and elongate aedeagal shaft and caliper-like, lanceolate subgenital plates with narrow base and membranous outer margin.
