Short desription: On podonotum, all setae short, smooth and needle-like, excluding seta j1 and marginal setae r5 , s6 which are finely barbed. On opisthonotum, setae J1–2 , Z1– 2 , S2 and marginal setae R 2–6 short, smooth and needle-like. Setae J3–5 , Z3–5 and S3–5 elongated, finely barbed with hyaline endings. Setae J5 are in an almost horizontal position, and apical parts of theirs extend towards each other. Although seta S4 reaching to margin of opisthonotum, seta S5 reaching to beyond of opisthonotum. Pores gdS2 located between setae Z3 and S3 , gdZ3 located between setae J5 and Z4 . Dorsal cavities distinct, large and strongly developed. Anterior margin of ventrianal shield with two pairs of setae ( JV1 and ZV1 ), glands gv2 present. Posterolateral tips of peritrematal shield reach to level of setae S1 ( Urhan, 2001 ; Bilki, 2021 ).
