Stictane Hampson Gen. rev.

Type species: fractilinea Snellen, Sumatra.

This genus has been placed in the Lithosiinae as a synonym of Manoba Walker since Hampson (1914), though Hampson (1900) earlier placed Manoba as a synonym of Nola. Manoba was returned to the Nolidae by Holloway & Miller (1995). Stictane is distinct and genuinely lithosiine.

The moths are small, grey, with a forewing pattern usually consisting of a darker grey medial band and blackish spots at the end of the cell and in submarginal and subbasal rows, usually angled. No veins have been lost from the cells of either wing, and the radial sector branching system is (R3 (R4, R5)), all the rest arising independently (Hampson, 1900; Fig 10a).

The male genitalia have the uncus long, slender, the valve with the saccular process shorter than the dorsal part, which is narrow, but variably structured apically. The aedeagus vesica usually contains cornuti which may be long or short.

The female genitalia have a short ductus, sometimes with a colliculum, and the corpus bursae is irregular, containing fields of scobination and often longer spines. There is usually an appendix bursae.

The genus needs further disentangling from Manoba as set out by Strand (1922, Lep. Cat., 26: 644); indeed, most species listed there under Manoba and placed in it subsequently are probably misplaced. True Stictane appears to be Oriental tropical, and probably also includes S. obliquilinea Hampson (Sri Lanka), S. fusca Hampson (Sri Lanka), S. bipunctulata van Eecke comb. n., S. umbrata van Eecke comb. n. (both Sumatra), and the species described below. There are probably many more undescribed. The genus extends to the Philippines (perhaps Eurosia costinota Wileman from Mindanao is a Stictane) and also to Sulawesi (S. rectilinea Snellen).

The two Sumatran species (Figs 9a, g) are the most similar in facies to the Bornean ones, but both have two spots at the end of the cell (obscure in umbrata) as in the type species, rather than one as in all Bornean species, and strongly bipectinate male antennae. The medial band of bipunctulata is narrow anteriorly but very broad over the posterior half. That of umbrata is broad throughout and diffuses into the distinctly greyer distal half of the wing. The male genitalia of bipunctulata (Fig 423) have some features in common with the first two Bornean species described below, but those of umbrata are distinctive (Fig 426): the valve is obliquely truncated apically, with a small spur on the more obtuse dorsal angle; the saccular spine is long but terminates subapically; the aedeagus is large, the vesica containing eight cornuti (two groups of three and two single ones).

Bornean species show some variability in wing markings, so only dissected male specimens are included in type series except for that of parvipectinata sp. n.
