Waipapamyia truncata Jaschhof & Kallweit sp. n.

( Figs 25 , 100–103 )

Diagnosis. Preepisternum 2 is entirely dark. The gonostylus bears a winding apical process ending in a blunt spine ( Figs 100, 103 ), whereas the apical spine in the other two species is pointed.

Description. Male. Thorax. Scutum mainly dark. Anepisternum 2, preepisternum 2, anepimeron 2, laterotergite, and mediotergite entirely dark.

Wing. Fig. 25 . Length 2.0 mm. A1 slightly curved.

Terminalia. Gonostylus with winding apical process ending in blunt spine, on dorsomesal margin 7 macrosetae in line plus 1 macroseta in some distance ( Fig. 103 ). Apex of ejaculatory apodeme widened, with minute trichia, 2 pairs of mesolateral processes and barblike subbasal structure ( Fig. 101 ). Parameres present as tusklike processes directed posterolaterally; parameral apodemes directed dorsolaterally ( Fig. 101 ).

Female. Unknown.

Distribution and phenology. Endemic to NZ: NO (TO), SO (BR). Occurs in both the main islands, in North Island concurrently with W. dentata and W. elongata . Adults captured in podocarp and beech forests in summer.

Etymology. From Latin, truncatus, truncate, referring to the blunt structure on gonostylus apex.

Types. Holotype. Male*. New Zealand, North Island, Taupo, Pureora Forest, Waipapa Reserve, in podocarp forest, 570 m, 12 Jan. 1984, by Malaise trap, J. Hutcheson (in NZAC). Paratypes. 2 (1*) males, SO, BR, L. Daniells Track 7 km E Springs Junction, in forest of red beech Nothofagus fusca and silver beech N. menziesii , 24 Nov. 2001, by sweepnet, U. Kallweit & A.
