Tamba occidinawa Holloway, 2005: 360

( Figs 9 , 24–25)

Type locality: Danum Valley , Sabah (Borneo, Malaysia)

Material examined: India, Andaman and Nicobar Islands, Great Nicobar Island : 1♂, Galathea , 07.xi.2018 (NZCZSI, 9286/H10) ; 2 ♂, Laxmi Nagar , 11.xi.2018 (NZCZSI, 9287/H10) ; 1 ♂, Steel Bridge, East West Road , 13.xi.2018 (NZCZSI, 9288/H10), K.C. Gopi & party leg .

Diagnosis: Forewing length: ♂ 15–16 mm. Externally, T. occidinawa is closely similar to T. dinawa (BethuneBaker, 1906) , but is slightly smaller and having paler reniform on forewing. Moreover, T. occidinawa lacks the subdorsal pale patch, just distal to the postmedial line on forewing, which is present in T. dinawa . Another similar looking species, T. rufipennis ( Hampson, 1895) has darker brown wings with blackish-brown double postmedial lines. In male genitalia, T. occidinawa differs from T. dinawa by broader and less spatulate costal process and asymmetrically bifid saccular process of valva.

Distribution: Indonesia (Sulawesi, Sumatra), Malaysia (Borneo), Thailand ( Holloway 2005), the Great Nicobar (present study).

Remarks: T. occidinawa is also a lowland rainforest species, usually recorded from altitudes below 200 m ( Holloway 2005).
