Scantiniina subtribe nov. Figs 47 , 48

Type genus.

Scantinius Stål, 1866.

Diagnosis.

The subtribe is identified and separated according to the following list of characters:

Hindwing trilobate, strongly notched at CuA2 with CuP-Pcu-A1 lobe slightly longer, as wide as Sc-R-MP-CuA lobe.

Posterior margin distinctly notched at A1 2.

Anal lobe posterior to A1 present, surpassing half-length of CuP-Pcu-A1 lobe, apically rounded and 1/2 thinner than the anterior ones, and with margins sub-parallel.

Sc-R-MP-CuA and CuP-Pcu-A1 lobes covered with a set of numerous transverse veins.

CuA and CuP merging at the anterior notch.

Pcu and A1 merging in basal half of forewing.

A2 present, single.

Note.

This subtribe is currently monogeneric and distributed in Indonesia (Sumatra), in Peninsular Malaysia and Sarawak ( Gnezdilov and Wilson 2007). Based on the strong CuA2-CuP notch and the reticulated Sc-R-MP-CuA and CuP-Pcu-A1 lobes, it is tentatively considered as a sister lineage to Parahiraciina , but without molecular data, its place in the phylogeny of the Hemisphaeriinae sec. Wang et al. (2016) remains uncertain.
