Euscelidius cornix sp. nov.

( Figs. 1 View FIGURE 1 A–G)

Measurement. Male: 3.49–3.83mm.

Description. Coloration. Ochraceous or brownish in general color ( Fig. 1A View FIGURE 1 ). Crown with dark brown marks, pair of spots at anterior margin followed by cross band slightly broadened in mid direction interrupted medially by longitudinal dorsal marginal ridge ( Fig. 1A View FIGURE 1 ). Pronotum with brown to dark brown spots ( Fig. 1A View FIGURE 1 ). Forewing yellowish brown with veins whitish in color ( Figs. 1A, C View FIGURE 1 ). Face mostly whitish or brownish, anterior margin of frontoclypeus with paired dark brown spots ( Fig. 1B View FIGURE 1 ).

Morphology. Head subequal to pronotum, not produced ( Fig. 1A View FIGURE 1 ). Crown about 1.7x shorter in median length than breadth between eyes ( Fig. 1A View FIGURE 1 ). Ocelli near anterior margin, close to eyes ( Fig. 1C View FIGURE 1 ). Frontoclypeus shagreen, moderately narrow ( Fig. 1B View FIGURE 1 ). Anteclypeus slightly widened apically ( Fig. 1B View FIGURE 1 ). Forewing macropterous, rounded apically, with multiple cross veins, four apical and three anteapical cells ( Fig. 1C View FIGURE 1 ).

Male genitalia. Pygofer side longer than high, with numerous well arranged macrosetae posteriorly, dorsoapical margin with incision near to mid-length ( Fig. 1D View FIGURE 1 ). Subgenital plates triangular, more in length than basal width, apically rounded, with single row of macrosetae laterally ( Fig. 1E View FIGURE 1 ). Style with apophysis very short, rounded, lobelike ( Fig. 1E View FIGURE 1 ). Valve broadly triangular ( Fig. 1E View FIGURE 1 ). Connective “Y”-shaped with arms well separated from each other, stem shorter than arms ( Fig. 1F View FIGURE 1 ). Aedeagal shaft broad at base dorsally, gradually tapered towards apex, lateral margin smooth, apically notched with pair of laterally directed small appendages ( Fig. 1F View FIGURE 1 ). Aedeagal shaft broad at basal half in lateral view, then declivous apically forming beak-like structure ( Fig. 1G View FIGURE 1 ).

Type material. Holotype: ♂, PAKISTAN, Khyber Pakhtunkhwa, Naran Valley , 2409m, August 2018, Coll. Hassan Naveed ( LSNU) . Paratypes: 1♂, Khyber Pakhtunkhwa, Naran Valley, 2409m, July 2017, Coll. Hassan Naveed ( NWAFU); 1♂, Khyber Pakhtunkhwa, Naran Valley , 2409m, July 2016, Coll. Hassan Naveed ( LSNU); 2♂, Azad Jammu and Kashmir, Rawalakot City, 1638m, 24 August 2018, Coll. Hassan Naveed ( LSNU) .

Remarks. This species resembles other Euscelidius Ribaut species in habitus color pattern but can readily be differentiated by the short, rounded style apophysis and aedeagal shaft with laterally directed apical appendages dorsally, broadened at the basal half and the crow’s beak-like apex in lateral view.

Etymology. The species epithet is the Latin noun ‘cornix’ meaning crow, referring to the crow-like aedeagal shaft in lateral view.
