Abstract
The flalid planthoppers arc very im-portant plant pests and these constitute the largest family of the superfamily Fulgo-roidea. Walker (1851, 1870), Melichar (1903), Kirkaldy (1903) anti Metcalf (1955) contributed a lot to this family from Ceylon, Thailand and Philippines. Distant (1906) made the largest contribution by describing 86 species belonging to 43 genera from this part of the oriental region. Metcalf and Bruner (1948) described a number of genera and species from Cuba and Guam, whereas Ghauri (1973) and Datta (1979) recorded some serious pests of tea plantation be-longing to this family from southern India. Shakila (1989) recorded 11 genera and 21 species in the family Flatidae for the first time from Pakistan. The genus Narowaknus is a new genus of the family Flatidae erected by the present author on the basis of one new species, i.e.11 globosus from Pakistan. Narowalenus gen. nov., has been erected to accomodate one species viz., N. globosus. This genus comes close to Neo-variata Shakila from which it could be differentiated on the basis of pattern of head, its carination, shape of aedeagus and to some extent the shape of paramere. This new genus can be diagnosed as under; Diagnosis: Head distinctly narrow, vertex almost rectangular, slightly less than twice as broad as long; pronoun) in length almost

equal to vertex; irons and clypeus confluent, carination absent. Tegmina twice as long as broad, apex smoothly ,rounded; marginal cross( veins all along coastal and apical margins, marginal granulation more dense in claval region. Anal segment moderately long, a ven-tral apical triangular extension projected considerably behind pygofer; aedeagus moderately long in ventral view, a ventral process present at about mid-length; a pair of semicircular and a small spiny apical pro-cess present; paramere, in lateral view, roughly rectangular, broader at apex, dorsal apical process spiny and prominent. Type species: Natuwalenus globosus, n.sp.
Narowalenus glohosus, n.sp.
Male: Form and colour: Length of male 4.0 mm; general body colour green, eyes dark brown, tip of labium brownish, spines on legs blackish, pronoturn and mesonotum uchra-ceous brown, veins green. Head and thorax: Head including eyes distinctly narrowed than transverse width of pronotum, vertex almost rectangular in shape, slightly less than twice as broad as long, with a slight antero-median convexity; pronoium much broader than long, its length nearly equal to that of vertex, scutel-lam triangular; Irons and clypeus confluent, carination absent (Fig. 1 A-C).
