Waipapamyia dentata Jaschhof & Kallweit sp. n.

( Figs 10 , 23 , 29 , 35 , 41 , 90–96 )

Diagnosis. Preepisternum 2 is bicolored, not entirely light or dark as in the other two species. The gonostyli in W. dentata resemble that in W. elongata in having a pointed apical spine, whereas the aedeagus/paramere complexes in these two species differ greatly (see Fig. 93 versus 99).

Description. Male. Head. Fig. 29 . Antennal flagellum as in Figs 94 and 95 .

Thorax. Fig. 35 . Scutum mainly light. Anepisternum 2, upper portion of preepisternum 2 and anepimeron 2 light, lower half to two thirds of preepisternum 2 dark. Laterotergite and mediotergite darker than pleura and scutum.

Wing. Fig. 23 . Length 1.8–2.2 mm. A1 almost straight.

Terminalia. Gonocoxites as in Fig. 90 . Gonostylus with strong, slightly curved, pointed apical spine and 7 macrosetae along dorsomesal margin ( Figs 90, 91 ). Ejaculatory apodeme notched apically, with 2 pairs of mesolateral processes and barblike subbasal structure ( Fig. 93 ). Parameres present as tusklike processes directed posteriorly; parameral apodemes directed dorsolaterally ( Fig. 93 ).

Female. Thorax. As in male.

Wing. Length 2.1 mm.

Distribution and phenology. Endemic to NZ: NO (TO). Known from only one locality, a podocarp forest, where adults were captured in December and January.

Etymology. From Latin, dentatus, toothed, referring to the strong spine on gonostylus apex.

Types. Holotype. Male*, New Zealand, North Island, Taupo, Pureora Forest, Waipapa Reserve, in podocarp forest, 570 m, 15 Dec. 1983, by Malaise trap, J. Hutcheson (in NZAC). Paratypes. 1* female, same data as the holotype (in NZAC); 6* males, same data as the holotype but Dec. 1983 (in NZAC); 1* male, same data as the holotype but 1 Dec. 1983 (in SMTD); 1* male, same data as the holotype but 29 Dec. 1983 (in SMTD); 1* male, same data as the holotype but 5 Jan. 1984 (in SMTD); 3* males, 2* females, same data as the holotype but 12 Jan. 1984 (in SMTD).

Other material. 5 males, same data as the holotype but Jan. 1984; 7 males, same data as the holotype but 12 Jan. 1984.
