Adraneothrips nilgiriensis (Ananthakrishnan) comb.n.

( Figs 9 , 22 )

Stigmothrips nilgiriensis Ananthakrishnan, 1971: 177 .

Described from 25 females and 13 males, two of the original females have been studied and are listed below. It is a dark brown species ( Fig. 9 ), with the head relatively elongate ( Fig. 22 ). Antennal segment III has 3 sensoria, and segment IV has 4. This species shares some character states with darwini , but the femora are brown, the postocular setae pointed to blunt, the notopleural sutures incomplete, the fore wing sub-basal setae S3 pointed, and the major setae on tergite IX pointed and almost as long as the tube. In contrast, the original illustration indicates widely complete notopleural sutures.

Specimens examined. INDIA, Ooty, 2 females from dry fern, 5.vii.1970, T.N. Ananthakrishnan; Davikulam, 1 female from dry fern, 9.ix.1970, T.N. Ananthakrishnan (UMIC).

Adraneothrips okajimai (Muraleedharan & Sen) comb.n.

Stigmothrips okajimai Muraleedharan & Sen, 1981: 227 .

Described from 10 females collected from dry leaves and twigs in Tripura, eastern India, this species was compared to Stigmothrips consimilis , a species now placed in Apelaunothrips . However, the pronotal notopleural sutures were illustrated as incomplete, and the generic position adopted here is presumably correct. Dr Kaomud Tyagi kindly informed us that there are 10 paratypes in the collections of the Zoological Survey of India, Kolkata, and that these all have three sensoria on antennal segment III and four sensoria on segment IV. This is a brown species, with the femora described as “golden yellow with brownish shade” the fore and hind tibiae yellow but the mid tibiae shaded brown.
