Holzezus compactus Krivokhatsky, 1992: 407 (type locality: Turkmenistan: Lebap, Repetek; holotype in ZISP). Krivokhatsky et al., 1996: 149 (Holzezus). Stange, 2004: 260 (Holzezus). Mirmoayedi et al., 2015: 10 (Holzezus).
Diagnosis. Adult: Body yellowish brown with dark brown markings (Fig. 2A). Vertex anteriorly with a pair of transversal dark brown bands and posteriorly with a pair of dark brown spots; a pair of dark brown spots present between scapes (Fig. 3D–E). Pronotum medially with a longitudinal dark brown stripe and laterally with a pair of oblique dark brown stripes, these stripes indistinct or discontinuous in some individuals; lateral margin with a pair of indistinct gray spots. Mesoscutellum with five dark brown dots and posterolaterally with a pair of subtriangular dark brown spots (Fig. 3D–E). Forewing rhegma and marking on cubital area indistinct (Fig. 2A). Male gonocoxites 9 small, shaped as a pair of thick hook-like structure (Fig. 3J–N). Female gonocoxites 9 with five to seven strong curved long digging setae (Fig. 3H–I).
Re-description of adult. Size. Head width: 2.04–2.66 mm; forewing length: 16.74–24.40 mm; hindwing length: 14.12–21.31 mm.
Head. Vertex obviously raised and rounded, covered with some short pale setae, anteriorly with a pair of transversal dark brown bands and posteriorly with a pair of dark brown spots. Scape and pedicel generally yellowish brown; flagellum yellowish brown, each of flagellomere basally with a dark brown circular marking. A pair of dark brown spots present between scapes. Ocular rim setae present, pale and needle-like. Frons pale yellowish brown (Fig. 3B). Gena wide. Clypeus pale yellowish brown with a pair of indistinct arched grey markings, covered with a few short dark brown setae. Labrum pale yellowish brown. Maxillary palpus generally pale yellowish brown, terminal segment brown. Labial palpus generally pale yellowish brown, terminal segment fusiform with a dark brown spot. Mandibles pale yellowish brown with distal half dark reddish brown (Fig. 3B).
Thorax. Yellowish brown with dark brown markings. Pronotum nearly as long as wide, with many short pale setae, lateral margin with some hairy long pale setae; medially with a longitudinal dark brown stripe and laterally with a pair of oblique dark brown stripes, these stripes indistinct or discontinuous in some individuals; lateral margin with a pair of indistinct gray spots. Intersegmental membrane between pronotum and mesonotum with a pair of dark brown spots. Mesoprescutum anteriorly with an inversed triangular dark brown marking, posteriorly with a triangular dark brown marking, laterally with a pair of dark brown spots; mesonotum medially with an inversed subtriangular dark brown marking, laterally with a pair of inversed “V” shape dark brown markings; mesoscutellum with five dark brown dots and posterolaterally with a pair of subtriangular dark brown spots. Metanotum with three dark brown spots and lateral margin with a pair of oblique “V” shape dark brown marking; metascutellum anteriorly with a pair of dark brown dots, medially with a dark brown spot, and posteriorly with a pair of dark brown spots. Meso- and metapleurae generally yellowish brown with some dark brown markings (Fig. 3D–E).
Legs. Yellowish brown, with many pale setae and a few dark brown setae. All femurs dorsally dark brown; tibial spurs spinelike, shorter than tarsomere 1; tarsomere 5 nearly as long as entire length of tarsomeres 2–4; tarsi yellowish brown each tarsomeres dark brown distally; pretarsal claws slightly curved, basally not protruded. Foreleg: Coxa pale yellowish brown, with a dark brown spot, covered with dense hairy pale setae; femur nearly as long as tibia; tibia medially with an indistinct dark brown spot. 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; femur 3/4 as long as tibia; tibia distally dark brown (Fig. 3A).
Wings. Narrow, mostly hyaline; posterior margin relatively straight; dark brown alternating with pale on longitudinal veins; pterostigma medially brown and laterally pale. Forewing MP sometimes suffused with an indistinct brown spot or a short transversal stripe; rhegma and markings on cubital area indistinct; RP origin distad MP and CuA fork; five to seven presectoral crossveins present; RP with six to seven branches; anterior Banksian line sometimes indistinct, posterior Banksian line distinct. Hindwing shorter than forewing; rhegma indistinct; four to five presectoral crossveins present; pilula axillaris absent (Figs 2A; 3A).
