03AE87B2244B783FFC02FBB577B52C9B.taxon	diagnosis	DIAGNOSIS. Based on the latest review of Touranella Attems, 1937 [Nguyen et al., 2023], the new species differs readily from all nine hitherto known congeners, including the sympatric T. hirsuta (see above), in the characteristic setation pattern of mostly four transverse rows of usually 5 – 6 + 5 – 6 long setae each on postcollum metaterga, combined with a roundly spatulform process on stalk between ♂ coxae 4, a very short and strong base of the gonopodal femorite supportmg an untwisted solenophore with an acuminate tip and only a little shorter solenomere, both latter similarly slender and strong (Figs 4 – 13).	en	Golovatch, S.

03AE87B2244B783FFC02FBB577B52C9B.taxon	description	DESCRIPTION. Length ca 13.5 mm, width of midbody pro- and metazona 0.9 mm and 1.2 mm, respectively (♂). Colouration dark chocolate brown with contrasting pale ozopore regions, tips of antennae, tergal setae, venter and basal podomeres; paraterga, tip of epiproct, strictures and distal podomeres lighter grey- to yellow-brown; gonopod telopodites yellow (Figs 4 – 8). Body moniliform, tegument generally smooth and shining, only in places faintly rugulose. Antennae moderately long and slender, slightly clavate, reaching past ring 3 when stretched dorsally; in length, antennomere 3> 2 = 4 = 5 = 6> 1 = 7 (Figs 4 – 7). Head setose nearly throughout, more sparsely so on vertex; epicranial suture faint; genae rounded. Interantennal isthmus ca 1.2 times as broad as diameter of antennal socket (Figs 6, 7). Collum suboval, with four transverse rows of 5 – 6 setae each side, only fore and caudal rows being regular; paraterga roundly angular caudally and finely rimmed (Fig. 5). In width, head = rings 5 – 16> 2 = 4> 3; body gradually and gently tapering caudally on rings 17 – 19 (Fig. 4). Postcollum paraterga poorly developed, set at about half metatergal height, only a little thicker on pore-bearing rings than on poreless ones, with several indistinct, partly setigerous incisions at lateral margin, poorly delimited both dorsally and especially ventrally, faintly arcuate to nearly straight, on pore-bearing rings mostly drawn caudally into small, blunt to increasingly acute teeth produced past rear tergal margin only on rings 18 and 19. Ozopores visible from above, lying inside oblong grooves a little in front of caudal corners of poriferous paraterga (Fig. 4). Metatergal transverse sulci starting with ring 4, but deep, strongly developed, mostly crescent-shaped, smooth and almost reaching the bases of paraterga on rings 5 – 18, clearly dividing each metatergum into two halves (Fig. 4). A shallow, but largely evident axial sulcus or line visible on both halves of metaterga 5 – 19 (Fig. 4). Strictures between pro- and metazona deep and narrow, clearly ribbed dorsally and laterally, smooth ventrally (Figs 4 – 7). Most of postcollum metaterga with four transverse rows of 5 – 6 setae in each row, two rows each half and both fore and caudal rows usually being more regular and complete; setae long, ca 1 / 3 as long as metaterga, pattern clearly traceable at least through insertion points (Figs 4, 5). Limbus thin and entire. Epiproct subtruncate, faintly concave at tip, with small papillae laterally (Fig. 4). Hypoproct subtrapeziform, paramedian setigerous papillae at caudal margin small, but evident (Fig. 7). Pleurosternal carinae small rounded crests visible only on rings 2 – 4. Sterna with faint cross-impressions, sparsely setose, without modifications except for a conspicuous, long, apically rounded, setose process on stalk between coxae 4 (♂) (Figs 6, 7). Legs very long and slender, densely setose, but devoid of tarsal brushes, about 2.5 – 3.0 times as long as midbody height, prefemora not swollen laterally (Figs 5 – 7); only each femur 1 with a distinct, curved, rounded, ventro-parabasal adenostyle (♂); gonopores inconspicuous. In length, femora = tarsi> prefemora = postfemora = tibiae> coxae. Gonopods (Figs 9 – 13) rather simple. Coxite (cx) subcylindrical, only slightly shorter than telopodite, with a distomesal cannula as usual. Prefemorite (prf) short, densely setose as usual. Femorite (fe) very strongly reduced, without process. Postfemoral region particularly long, slender, suberect and only slightly twisted, consisting of a rod-shaped solenomere (sl) and a slightly longer solenophore (sph), the latter acuminate on top and distally sheathing much of sl.	en	Golovatch, S.
