Manis gen. n. and Manis himalayensis sp. n. are described from Himachal Pradesh, India.

The new monobasic genus is most closely related to Malac'hiella Malaise

Heptctpotamius Malaise from which it differs in several important characters.

Introduction

Most of the scattered work on Indian Allantinae was published by Malaise (1934, 1935, 1945, 1957,1961). Later, Malaise (1963) also presented a key to the world genera of Selandriinae (cur- rently including the subfamilies Selandriinae, He- tarthriinae, Allantinae, Nematinae and Blenocam- pinae). No new genera of the Allantinae have been added to the Indian fauna since the publication of Malaise's key. With the addition of the genus described below, the number of allantine genera in India now scores 18.

Abbreviations: (EL) eye length, (IATS) inner apical tibial spur, (lCD) intercencheri distance, (IDMO) intero- cular distance at level of front ocellus, (lTD) intertegular distance, (LID) lower interocular distance, (MB) meta- basitarsus. (OATS) outer apical tibial spur, (OCL) oculo-occipital line. ^(OOL) oculo-ocellar line, and {POL) postocellar line.

Manis gen. n.

Description of female

Heacl. Antenna with 9 segments: apical 4 ^seg-

ments compressed. Clypeus with circular incision up to 2/5 of its medial length and with blunt iateral teeth (Fig. 1). Mandibles symmetrical and bent almost at right angle. Eye protruding (Fig. 2); lo- wer margin reaching below level of antennal soc- ket. Frontal area elevated at level of eyes. Head parallel posterior to eyes (Fig. 2).

Legs. Tarsal claw with long apical and relatively short subapical tooth (Fig. 3); basal lobe absent.

l4zings (Figs 4, 5). Anal cell cross vein on fore wing somewhat oblique (Fig. a). Hind wing with- out closed middle cell; anellan cell petiolate; ner- vellus curved towards anellan petiole, but almost perpendicular to brachiellan vein (Fig. 5).

Etymology. The genus is named after Dr M. ^S.

Mani, ^an authority of Himalayan ecology in India.

The gender is masculine.

T.y-pe

species. Manis himalavensls sp. n. by present designation. The genus is monobasic.

D

istibution. India, Himachal Pradesh.

Remarks.In Malaise's (1963: 179-180) key to the world genera, the new genus runs to couplet 106, where it differs from both genera keyed out here, i.e. Malochiella Malaise and Heptapotamius Ma- laise (note that Mallat'hiella Malaise, 1963, is an

unjustified emendation). The head of Manis is subparallel behind the eyes, whereas it is evidently becoming narrower posteriad in both other genera.

Other differences lrom Malachiella are: (l) tarsal claw with subapical claw short (long in Malac- hiella) and basal lobe absent (minute in Malac'- hiella), and (2) mandibles symmetrical (subsym-

metrical in Malachiella). It diff'ers fron.r

Heptapotamiu.s in the more protruding eyes and

the compressed flagellum of antenna (not _com-

pressed in H

ptapotamius).

Type material. Holotype: female, Himachal Pra-

desh, Dalhousie, Kalatop, 2,380 m ^a.s.l.,

25.vi.1986. Paratypes 13d I ? ^{with same data as}

holotype. Type material deposited in Indian Agri- cultural Research Institute, New Delhi.

Etymology. The species is named after the "Great Himalayas", where the type locality is situated.

Distribution. India. Himachal Pradesh.

Remarks. Manis himalayensis is most similar to Malachiella rufithorax Malaise. The two species are easily separated on the generic characters.
