(ProQuest: ... denotes non-USASCII text omitted.) Abstract A cladistic analysis of the fourteen genera of sub-family Grylline is attempted using apomorphic characters which was selected from their external morphological characters, male and female genital components. Recently a cladistic analysis of the Nemobine crickets is attempted including 14- species of 5- genera from Pakistan, (Kamaluddin and Khan, 2012) Kamaluddin et al., (2001) discussed the external morphology of Gryllus bimaculatus(DeGeer) and compared with the representative of sub-family Nemobiinae and also described the apomorphic characters to build a background for their cladistic. Materials and Methods The characters of included taxa were coined from all body structures including head thorax, abdomen and ovipositors and also from available literature. (Comphogryllusto Gryllus). g2 Face more or less flattened in males (Loxoblemmus to Coiblemmus). g3 Males with strongly flattened face (LoxoblemmustoParasciobia). g4 Males with flattened or somewhat concave face (Scapsipedus and Coiblemmus). h0 Forehead normal. h1 Forehead with more or less strongly prolonged (LoxoblemmustoParasciobia). h2 Forehead small (Scapsipedus and Coiblemmus). i0 Front of the rostrum smooth. i1 Front of rostrum strongly projecting in males, corneous or presenting a membranous process (Meristoblemmus and Parasciobia). i2 Front of the rostrum of male projecting but simply angular (Loxoblemmus). i3 Front of rostrum subangulate in male (Coiblemmus). j0 Elytra well developed in both sexes. j1 Elytra well developed at least in males (Gryllodes to Gryllus). j2 Elytra of males with well-developed mirror (Gryllopsis and Gryllus). j3 Elytra of males with indistinct or small mirror displacement towards the apex (Callogryllus). j4 Elytra very simple in males (Itaropsis). k0 Females with highly developed elytra. k1 Females with more or less perfectly developed elytra (Gryllus). k2 Females with short lateral elytra (Gryllopsis). κз Females with very short elytra (Parasciobia). k4 Females with highly reduced elytra (Meristoblemmus). l0 Membranous process smooth. l1 Membranous process non-divided unilobed (Parasciobia). l2 Membranous process divided into two large lobes (Meristoblemmus). m0 Mandibles of the male normal. m1 Mandibles of the males very strong and lengthened (Scapsipedus). n0 Tympanum absent. П1 Tympanum on the internal face (Landreva).
