Colouration. Variable, body above ( Fig. 18 View FIGURES 18–21 ) ochraceous with irregular black markings (sometimes with greenish reflexions) formed by the congregation of black punctures. Antennae colour variable, usually brown to black, first segment ochraceous except a broad stripe laterally and one short, narrow stripe on ventral side; remaining segments brown to black, segment IV and V mostly black except the basal 1/5 th pale yellow or cream coloured. Humeri black with greenish reflexions, nodule of humeri with minute ochraceous spot. Corium light brown sometimes with reddish tinge, membrane fuscous with veins black, scattered black spots of variable shapes towards apex.

Ventral side ( Fig. 19 View FIGURES 18–21 ) including head pale ochraceous except the black colouration laterally formed due to punctuation. Labium ochraceous except apex, black. Legs ochraceous except apex black. Tooth on posterolateral angles of ventrites III to VII and apical half of tarsal claws, black.

Integument and vestiture. Body above covered with coarse, dense, round, black punctures, connexivum with fine, dense and conclourous punctures. Ventral side of body including legs with dense, round, black punctures, concentrated towards lateral sides of body, medially with concolourous punctures.

Body glabrous except the following antennae, legs, disc of head and pronotum, humeri, anterolateral margins of propleura and abdominal segments with moderately elongate, golden setae. Male genitalia with genital capsule pilose; ventral side of genital capsule with moderately elongate golden setae on anterior one third and the remaining region on ventral side with short sparse brown setae; outer posterior rim of genital capsule with moderately elongate golden setae; infoldings of ventral rim developed on lateral sides of posterior opening of genital capsule with mat of dense, elongate, thick, black setae. Female genitalia with valvifers VIII possessing small, sparse brown setae, valvifer IX medially with dense tuft of moderately elongate, dark brown thick seate; posterior apex of laterotergite IX with golden brown setae; laterotergite VIII with sparse brown setae.

Mandibular plates straight, slightly covering apex of clypeus, not meeting in front of clypeus, apex of mandibular plates narrowly rounded, nearly equal to clypeus, but not shorter; clypeus open apically. Compound eyes moderate size, rounded and protruding out. Antenniferous tubercles small and well visible from above. Antennae five segmented, slender, first segment slightly swollen, second segment geniculate and slightly thickened apically. Antennal segments from shortest to longest: I<II>III<IV>V. Buculae low, quadrangular anteriorly, partly covering the labial segment I. Labial segment I slightly surpassing bucculae; apex of labium reaching posterior margin of third abdominal segment.

Dorsal rim shallowly concave than ventral rim, the dorsolateral margins of dorsal rim arcuately concave and oblique to straight median region of dorsal rim; infoldings of dorsal rim with small, transverse median extension. Paramere ( Figs 28–29 View FIGURES 28–33 ). Crown broad with apical margin formed as scaly, sclerotized ridge terminate as a blunt and rounded projection; outer margin of main axis of paramere right angle to the sclerotized ridge; stem with a short, apically rounded process towards inner margin, possessing setae; basal apodeme developed into a rounded, laminate disc like structure. Articulatory apparatus ( Fig. 30 View FIGURES 28–33 ). Basal plate and support bridge complex fused to form subtriangular plate-like structure with saddle shaped capitate process attached through dorsal connectives. Phallus. Phallotheca sclerotised and constricted towards both ends; proximal end slightly twisted ventrad possessing short angular process ventromedially; distal end broader than proximal end; three pairs of conjunctival processes-dorsal pair of conjunctival processes semisclerotised, median conjunctival processes membranous, trilobate or with three lobes, ventral pair moderately elongate, basally fused and gradually narrowing towards apex; processes of aedeagus (=penial lobes) (pa) sclerotized, inwardly directed apically and with angulate inner angles; aedeagus (ae) short and tubular.

Bionomics. Adults were found inhabiting tree barks of Guava ( Psidium guajava L.) and apple ( Malus domestica Borkh. )

Distribution. Himachal Pradesh: ‘ Kulu’ (=Kullu) ( Ghauri 1977), Uttarakhand: Dehradun (new record)

Remarks. This species can be easily differentiated from other species of Sarju by the presence of a distinct but, short angular tooth in front of compound eyes ( Fig. 22 View FIGURES 22–27 ), located right angle to the main axis of head. The members have small body size as compared to other species of Sarju .
