diagnosis
Diagnosis Medium size (up to 1.42 mm) entomobryid. Eyes and pigment absent. Scales present on the body, coarsely striate with striations very short, and leaf-like with tip pointed; scales on ventral side of manubrium present but narrower than those on body. Polymacrochaetotic chaetotaxy. Prelabral and labral chaetae 4 / 5, 5, 4, all smooth. Labrum margin with inverted median U-form intrusion. Chaetae mel 1 l 2 of labium smooth. Five papillae of labial palp with 0, 5, 0, 4, 3 guard chaetae. Subapical chaeta of maxillary outer lobe slightly stronger than apical one; three smooth hairs on sublobal plate. Four antennal segments (I and II not subdivided, IV not annulated). No apical bulb. Fourth abdominal tergite 2.33 to 3.62 times longer than the third. Trochanteral organ of leg III always present, with 7 to 17 spines. Inner differentiated tibiotarsal chaetae ciliated with ciliations not closely appressed to axis. Ungual basal paired teeth unequal, outer one large. Tenent hair of tibiotarsus pointed and subequal to unguiculus. Tenaculum with 4 + 4 teeth and one large striate chaeta. Manubrium without smooth chaetae. Dens without spines and scales. Bidentate mucro with a short basal spine. Male genital plate of the papillate type.
discussion
Remarks Szeptyckiella gen. nov. belongs to Willowsiini due to the absence of dental scales. It is closest to Hawinella in body habitus, scale morphology and distribution, and in having smooth prelabral and labral chaetae and no antennal apical bulb or eyes. It differs from Hawinella in having bidentate mucro. Szeptyckiella gen. nov. also resembles Sinella, from which it differs only in having scales. Key to Willowsiini genera
