MATERIAL EXAMINED.

TYPE MATERIAL. INDONESIA, Sangir Island : Holotype ♀: [Sangir (Doherty)] [ diana Dist. ] [Type] [Distant Coll. 1911—383.] ( BMNH).

DIAGNOSIS. (1) disc of frons black-brown between carinae ( Fig. 8 E ); (2) tegmina mostly olivaceous green on corium ( Fig. 8 A ); (3) nodal line of tegmina C-shaped in middle ( Fig. 8 A ); (4) membrane of tegmina representing less than 1/3 of LTg ( Fig. 8 A ); (5) hind wings with anal and sutural zones whitish ( Fig. 8 A ); (6) femora black-brown ( Fig. 8 B ).

ADDITIONAL DESCRIPTION.

Measurements and ratios. LT: ♀: (n = 1, extrapolated): 30.0 mm; LTg/BTg: 2.24; BV/LV: 2.74; BF/LF: 0.88; BT/LP + LM: 1.2; LM/LP: 1.7; LMe/LCo: 0.61.

DISTRIBUTION. Currently known only from Sangir Island north of Sulawesi ( Fig. 3 ) .

NOTE. Scamandra diana Distant, 1892 is rather similar to S. sanana sp. nov. but differs from the latter by (1) the narrower black area of frons, very slightly surpassing the longitudinal carinae (broader and largely surpassing carinae in S. sanana sp. nov.); (2) the apical margin of tegmina oblique at sutural angle (rounded in S. sanana sp. nov.); (3) the membrane of tegmina representing only less than 1/3 of LTg (membrane representing nearly half of LTg in S. sanana sp. nov.).
