Diagnosis

See Itoh (2001). External morphology of adult and male genitalia ( Figs 37–40 ).

Material examined

JAPAN • 1 ♂; Okinawa, Is. Ishigakijima, Tonoshiro-Takeda ; 29 Feb. 2004; T. Nakata leg.; Matsumoto det.; TMC • 2 ♂♂, 2 ♀♀; same collection data as for preceding; TMC .

Remarks

Itoh (2001) described Miridiba hirsuta based on a male holotype and five paratypes (2 males and 3 females). According to the author ( Itoh 2001), this species is closely allied to M. trichophora , but M. hirsuta is distinguishable by the larger size, sharper apices of upper branches of parameres, and antennal club weakly more elongate in male. We have studied five specimens (TMC) collected from the type locality and identified by Mr Matsumoto as M. hirsuta , observing some differences with the type of M. trichophora in endophallus. However, given that we were unable to examine the types of M. hirsuta , it is not possible to confirm that these differences characterize M. hirsuta . Until the types of M. hirsuta are studied, we consider it a valid species. According to the antenna 9-segmented and the parameres described by Itoh (2001), this species is included in this genital morphotype I “ Trichophora ”.

Distribution

Ryukyus.
