( Fig. 1A–J View FIGURE 1 )
Measurement. Male: 3.9mm.
Description. Coloration. General color chocolate brown ( Fig. 1A–D View FIGURE 1 ). Crown anterior portion black with two conspicuous black spots normally present in middle adjacent to eyes ( Fig. 1A, 1C View FIGURE 1 ). Eye reddish brown, surrounded with yellow band ( Fig. 1A–D View FIGURE 1 ). Face black with yellowish patch on frontoclypeus ( Fig. 1D View FIGURE 1 ). Pronotum with black band along the anterior margin, whitish across the middle while yellowish brown at the posterior margin ( Fig. 1A, 1C View FIGURE 1 ). Mesonotum and scutellum yellowish brown ( Fig. 1A, 1C View FIGURE 1 ). Thorax and abdomen black in ventral and lateral view ( Fig. 1B View FIGURE 1 ). Abdominal segments separated by yellowish bands ( Fig. 1B View FIGURE 1 ). Forewing dark brownish with prominent venation ( Fig. 1A–B View FIGURE 1 ).
Morphology. Crown narrower than pronotum, with anterior margin slightly angulate and smoothly curved to face ( Fig. 1A–D View FIGURE 1 ). Crown almost equal to or a little longer than breadth between eyes ( Fig. 1A, 1C View FIGURE 1 ). Ocellus next to eye slightly below anterior margin of crown ( Fig. 1B, 1D View FIGURE 1 ). Antennae long and thin. Face slightly longer than broad ( Fig. 1D View FIGURE 1 ). Pronotum median length a little smaller than median length of crown with posterior margin slightly concave ( Fig. 1A, 1C View FIGURE 1 ). Mesonotum and scutellum generally shorter than pronotum. Scutellum with a transverse impression in middle ( Fig. 1C View FIGURE 1 ). Forewing macropterous ( Fig. 1A–B View FIGURE 1 ).
Male genitalia. Pygofer lobe broad basally with apex truncate ( Fig. 1E View FIGURE 1 ). Pygofer side with few dorsal macrosetae ( Fig. 1E View FIGURE 1 ). Subgenital plate large, triangular, with a row of uniseriate macrosetae ( Fig. 1F View FIGURE 1 ). Valve triangular. Style narrow with digitate apophysis, laterally curved ( Fig. 1G View FIGURE 1 ). Connective H-shaped with stem slightly shorter than arms ( Fig. 1H View FIGURE 1 ). Aedeagal shaft long, bent at near base, nearly parallel to aedeagal base, with a slight dorsal curve at mid-length in lateral view, apex pointed and slightly curved dorsad, gonopore apical ( Fig. 1I–J View FIGURE 1 ).
Material examined. Holotype: Pakistan: Punjab: ♂, Attock , 33°51′4.2192′′ N, 72°15′59.292′′ E, sweeping hand net, 16 June 2021, coll. Waqar Khan and Bismillah Shah. GoogleMaps
Distribution. Pakistan [Attock ( Fig. 2 View FIGURE 2 )].
Remarks. The new species described in this paper appears to key out to S. indrus (couplet 8) in our previous key (See Shah et al., 2020b). However it can readily be distinguished from S. indrus by the crown with anterior portion black ( Fig. 1A, 1C View FIGURE 1 ); two conspicuous black spots normally present in middle adjacent to eyes ( Fig. 1A, 1C View FIGURE 1 ); and face black with yellowish patch on frontoclypeus ( Fig. 1D View FIGURE 1 ). Also, the new species has coloration similar to some species described from the Americas (e.g., Stirellus bicolor , Stirellus picinus ) and Australia ( Stirellus petfordensis ).
Etymology. This species is named for the country Pakistan, where the type specimen has been collected.
