Scaphoideus Uhler

Remarks. This genus has been revised by Viraktamath & Mohan (2004) for the Indian subcontinent. We figure in the following species the unusual articulation found in Scaphoideus and some other genera where the aedeagus is disassociated from the connective and attaches dorsally to the Xth segment and pygofer ( Fig. 8 d). It is unclear in this situation how the aedeagus is positioned during copulation a s the only points of leverage are the strengthening arms of the interconnecting membrane ( Fig. 8 d) rather than the articulation to the connective. Also, in this species one would expect that the very small aedeagus (compare Figs 8 g to 8e, to same scale) might add to the difficulty of copulation.

Scaphoideus harlani Kitbamroong & Freytag (Plate 1, f; Fig. 8 ).

Material examined. Pakistan: 13, Bala Kot, 10.xi.89; 13, 1Ƥ, China, 16.vii.1985 ( BMNH).

Remarks. This species, previously known only from Thailand, is distinctive in having a very small aedeagus and ‘horse-shoe’ shaped paraphyses of the connective ( Fig. 8 e). Our figure of the aedeagus ( Figs 8 f– h) shows the processes not shown in the original figures.

Chiasmini

Remarks. This tribe has recently been reviewed by Zahniser (2008). With respect to the tribal characters given in the key all members of the tribe except Prasutagus have a ‘hinged’ aedeagal shaft.
