Genus Aritranis Förster, 1869 View in CoL View at ENA

Aritranis Förster, 1869: 187 View in CoL . Type species: Cryptus exploratory Schulz, 1906 . Designated by Viereck (1914).

Pycnocryptus Thomson, 1873: 471 , 500. Type species: Ichneumon peregrinator Linnaeus, 1758 sensu Gravenhorst, 1829 = Ichneumon director Thunberg, 1822 . Monobasic.

Cylindrocryptus Ceballos, 1921: 50 . Type species: Cylindrocryptus nitidus Ceballos, 1921 . Original designation.

Townes (1970) treated both Aritranis View in CoL (including Hoplocryptus Thomson, 1873 View in CoL ) and Pycnocryptus as valid genera. Then Schwarz & Shaw (1998) reviewed these genera and they treated that Hoplocryptus View in CoL is a valid genus and that Pycnocryptus is a synonym of Aritranis View in CoL . Aritranis View in CoL is morphologically similar to Hoplocryptus View in CoL , but it can be distinguished from the latter by the following character states: dorso-lateral carina of T I absent or indistinct based of spiracle (distinct based of spiracle in Hoplocryptus View in CoL ), postpetiole rather distinctly convex dorsally in lateral view (rather weakly convex in Hoplocryptus View in CoL ) and apical margin of clypeus without a tooth except for A. nigripes View in CoL group sense Schwarz (with a more or less distinct tooth or a pair of teeth in Hoplocryptus View in CoL ).

In Japan, six species of Aritranis s. lat. had been described by Uchida (1936, 1952, 1956) and Momoi (1963, 1968, 1973) while all of them were transferred from this genus to Hoplocryptus Thomson, 1873 ( Yu et al., 2016). Schwarz (2005) recorded a single species, Ar. occisor (Gravenhorst, 1829) from Japan. In this study, I describe a new species from Japan below.
