Coloration and morphology. Yellowish brown to greenish in color. Head variably shaped, slightly to strongly produced. Ocellus present slightly below or on anterior margin. Frontoclypeus straight to slightly convex in profile. Clypeal sulcus prominent. Forewing variably developed, brachypterous to macropterous, usually with three anteapical cells, inner anteapical cell opened at base.
Male genitalia. Pygofer triangular in lateral view, dorsal margin sloping posteriorly and mostly straight or concave distally with short tooth present on the apical half near ventral margins. Valve long, triangular. Style with preapical angle distinct. Connective Y-shaped or H-shaped. Aedeagal base triangular, shaft elongate and slender with no basal hinge and strongly curved anterodorsally. Gonopore apical or subapical.
Distribution. Worldwide.
Remarks. Duan et al. (2019) provided a detailed description of the tribe. Stirellus is heterogeneous and the largest genus of the tribe, distributed worldwide. Variation in external morphological characters including body proportions and coloration explain why many diverse forms were considered previously to represent separate genera. Previously Khatri & Webb (2010) reported 3 known Stirellus species from Pakistan. Recently, Naveed et al. (2020) added 2 additional new species to make a total of 5 known species from Pakistan.
