Subgulina kerzhneri Krivokhatsky, 1996: 315 (type locality: Mongolia: South-Gobi aymak, 60 km east of spring Talyin-Bilgakh- Bulak (Gurvantes County); holotype in ZISP). Stange, 2004: 283 (Subgulina). Krivokhatsky, 2011: 15 (Subgulina).
Diagnosis. Adult: Body pale brown with dark brown markings (Fig. 2B). Most pores on head, pronotum, mesonotum, and legs each suffused with a dot. Vertex anteriorly with a pair of dark brown spots and an indistinct transversal dark brown band; covered with short black and pale setae (Fig. 4C). Pronotum medially with a longitudinal dark brown stripe, anterolaterally with a pair of dark brown spots, laterally with a pair of corrugated brown stripes. Mesoprescutum dark brown with a pair of pale brown spots; mesoscutellum with a sagittal dark brown marking (Fig. 4C). Forewing costal space with a dark brown spot proximad pterostigma; posterior crossvein of hypostigmal cell corrugated; basal forked part of Cu suffused with an indistinct brown band; rhegam shaped as an indistinct brown spot; cubital area basally with an indistinct curved brown stripe, and an indistinct brown marginal band (Fig. 4A). Male gonocoxites 9 small, shaped as a pair of thick hook-like structure, rounded in lateral view (Fig. 4H–L). Female pregenital plate not protruded; gonocoxites 9 protruded with six to seven strong curved long digging setae (Fig. 4F–G).
Re-description of adult. Size. Head width: 2.26–2.45mm; forewing length: 16.58–17.23 mm; hindwing length: 16.12–16.96 mm.
Head. Vertex slightly raised, covered with some short black and pale setae, most pores each suffused with a black dot; anteriorly with a pair of dark brown spots and an indistinct transversal dark brown band. Scape and pedicel pale brown and brown; flagellum pale brown, each of flagellomere basally with a dark brown circular marking. Ocular rim setae present, pale and needle-like (Fig. 4C). Frons pale brown. Gena pale yellowish brown, wide. Male bears a rounded dark brown sac-like structure (“goitre”) from the gula. Clypeus pale yellowish brown with a pair of indistinct arched grey markings, covered with a few short dark brown setae. Maxillary palpus generally pale brown. Labial palpus generally pale yellowish brown, terminal segment swollen fusiform with a dark brown spot. Mandibles pale yellowish brown with distal half dark reddish brown (Fig. 4B).
Thorax. Pale brown with dark brown markings. Pronotum nearly as long as wide, with many short pale and black setae, most pores each suffused with a black dot, lateral margin with long pale setae; medially with a longitudinal dark brown stripe, anterolaterally with a pair of dark brown spots, laterally with a pair of corrugated brown stripes. Mesothorax dorsally covered with many short pale and black setae, most pores each suffused with a black dot; mesoprescutum dark brown with a pair of pale brown spots; mesonotum medially with a dark brown marking and lateral part generally dark brown; mesoscutellum with a sagittal dark brown marking. Metanotum medially with a dark brown spot and laterally with a pair of curved dark brown markings; metascutellum anteromedially dark brown. Meso- and metapleurae generally yellowish brown with some dark brown markings, covered with many short pale setae (Fig. 4C).
Legs. Brown and pale brown, with many pale setae and a few dark brown setae. All femurs dorsally dark brown, with many short thick pale setae and a few short black setae; tibia with many short pale setae and a few thick dark brown setae; tarsi yellowish brown each tarsomeres dark brown distally; tarsomere 1–4 each with a pair of spinelike dark brown setae; tarsomere 5 longer than entire length of tarsomeres 2–4 but shorter than length of tarsomeres 1–4; pretarsal claws slightly curved, basally protruded. Foreleg: Coxa pale yellowish brown, with many long and short thick pale setae; femur basally with a short black sensory hair, pores on femur and tibia each suffused with a black dot; tibia medially with a dark brown spot and distally dark brown; tibial spur reaching tip of tarsomere 1. Midleg: Coxa pale yellowish brown, covered with a few short pale setae, other characters similar to foreleg. Hind leg: Coxa pale yellowish brown, covered with a few short pale setae; tibia distally dark brown; tibial spurs shorter than tarsomere 1 (Fig. 4A).
Wings. Narrow; posterior margin relatively rounded; dark brown alternating with pale on longitudinal veins; pterostigma pale. Forewing costal space with a dark brown spot proximad pterostigma; basal forked part of Cu suffused with an indistinct brown band; rhegam shaped as an indistinct brown spot; cubital area basally with an indistinct curved brown stripe, and an indistinct brown marginal band; RP origin slightly distad MP and CuA fork; posterior crossvein of hypostigmal cell corrugated; four to six presectoral crossveins present; RP with six to seven branches. Hindwing slightly shorter than forewing; costal space with a dark brown spot proximad pterostigma; rhegma indistinct; two presectoral crossveins present; pilula axillaris absent (Figs 2B; 4A).
Abdomen. Pale yellowish brown with dark brown markings; shorter than hindwing. Terga 2–7 each medially with a longitudinal dark brown stripe, laterally with a pair of dark brown stripes. Male without hairy pencil-like structure. Female sternum 7 truncated on distal margin, without digital projection. Male terminalia and genitalia. Tergum 9 subrectangular. Sternum 9 short, subrectangular in ventral view (Fig. 4D–E). Gonocoxites 9 small, shaped as a pair of thick hook-like structure, rounded. Gonocoxites 11 sagittal arched in ventral view; gonostyli 11 oblate in lateral view; gonapophyses 11 long wedge-shape, curved in lateral view (Fig. 4H–L). Ectoproct nearly trapezoidal in lateral view, posteroventral lobe slightly protruded, with many long setae (Fig. 4D–E). Female terminalia. Pregenital plate not protruded. Gonocoxites 8 slender, short digitiform, with a few long setae, one paired. Gonocoxites 9 protruded with six to seven curved long digging setae. Ectoproct truncated on distal margin, posteroventrally slightly protruded (Fig. 4F–G).
