REVISION OF GENUS ZA MA RA DA 183 



Externally somewhat similar in colour and pattern to saburra in the vulpina- 

 group, but distinguished by its smaller size, its brightly coloured head and antennae 

 and by the solidly marked, not ringed, discal mark on each wing. Structurally 

 apparently without close relative; placed tentatively in the metrioscaphes-group 

 because of the crenulate and serrate-margined sterigma in the female genitalia. 



Distribution. Zambia, Zaire. 



Material examined. 



Zambia: Abcrcorn, ii. 1954 {D. Vesey- Fitzgerald), 1 <$ (Zamarada rubrifascia 

 Pinhey, paratype) (BMNH); ibidem, xii. 1963-ii. 1964, 1 $ (NMR, Bulawayo); 

 Abercorn, i-ii. 1956 (Zamarada rubrifascia Pinhey, paratypes), I <$ (BMNH), 2 $

 Congo'): Shinkolobwe, 3.VL1931, 1 9; Kasai, Sankaru, Bena Dibele, iv. 1959 

 (R. H. Carcasson), 1 $ (both BMNH).

 Zamarada plana Bastelberger, 1909 : 101. 



$ genitalia (Text-figs 300, 301). Uncus short, tip finely tapered and curved ventrad. 

 Ventral plate of gnathus minutely scobinate, tip slightly broadened and rounded. Valve 

 simple, apex narrowly rounded; dorsal process with slender, digitate projection near base. 

 Aedeagus finely tapered, without projection. Fulcrum slightly sinuous and serrate on one 

 surface in apical fifth. 



9 genitalia (PI. 64, figs 706, 707). Posterior margin of lamella antevaginalis irregularly 

 serrate; lamella jiostvagin.il is sclerotized, except for a series of membranous, concentric, 

 semicircular folds medially. Signum stellate, perimeter long-spined. 



Two subspecies are recognized, distinguished by the colour and pattern of the 

 wings. The nominate subspecies occurs at Kigonsera in S.W. Tanzania, at 

 Luchenza in Malawi, in Rwanda and in Burundi. Subsp. denticincta also occurs 

 in Malawi, at Mt Mlanje, along the Lunchenya river near Mlanje and at Nkata 

 Bay and its distribution extends thence southwards to Cape Province. Specimens 

 of the nominate form occurring in the same locality as subsp. denticincta are 

 recorded from Dondo Forest in Mozambique (1 <$ nominate form, 2 $, 1 $ denti- 

 cincta), from Weenen, Natal (1 $ nominate form, 2 $ denticincta) and from Muden, 

 Natal (1 <$, 1 $ nominate form, 3 $ denticincta). 



The pin-data labels give no indication of the vegetation zones in which the 

 specimens were taken; until it is known whether plana and denticincta represent 

 subspecies or seasonal forms, the two taxa, which are identical in the structure of 

 the genitalia of both sexes, are accorded subspecific rank.
