paratypes
sides with orange marks; mesonotum light orange-brown, scutellum stramineous. Forewings slightly powdered; a lightly infuscated mark at clavus tip; very faintly infuscated from hind margin distad of clavus to base of Ms1, around base of Ms2, and along apical crossveins; an orange-red mark around base of last subcostal sector; most veins orange-red, claval veins and some sections of other veins white; in some
paratypes
orange veins mainly confined to Sc, R and M; costa with 3 red sections; apical margin orange; hind margin colourless, but a section around clavus tip bright orange-red; 3 dark spots on base of Sc+R. Hindwings colourless but most veins orange-red. In profile junction of vertex and face slightly angulated; subantennal processes not connected to margins of facial carinae; rostrum reaching post trochanter. Forewings with Sc+R fork just before middle of wing; basal median cell about as wide as basal cell between Sc+R and M; no triangle at base of Ms1. Male genitalia with pygofer narrow. Genital styles elongated; proximal dorsal process short and slender; distal dorsal process elongated. Apical part of aedeagus small, with a dorsal impression and a short membranous lobe at the tip.

Diagnosis.
Saccharodite dionaea
resembles
Sa. insulana
sp. nov.
, also from the Solomon Isl. It can be distinguished by the hind margin of the forewings which has a bright orange-red section near the clavus tip. In
Sa. insulana
this part of the hind margin is colourless. Usually
Sa. dionaea
can be also recognized by the stronger orange coloration on head and body and by the weaker coloration of the forewing veins. It differs from
Sa. basipunctulata
(Melichar)
, also found in the Solomon Isl., in the orange-red colour of head and body.
