Typhloiulus (Typhloiulus) kotelensis: Strasser 1962

Material. Neotype (designated herewith!) ♂ broken into 4 pieces, with dissected gonopods ( NMNHS), Bulgaria, Shumen Distr., Shumensko Plateau, Kyoshkovete Park, soil sampling, 16.IX.2009, D. Bachvarova leg.

Additional material. 2 ♀ ( US), same sample as the neotype, 54+2+T body rings, l = 29 mm, h = 1.5 mm, and 60+1+T body rings, l = 35 mm, h = 1.6 mm; 4 ♂ (one pair of gonopods prepared for SEM), 4 ♀, 1 juv. ( ZMUC), Bulgaria, Stara Zagora Distr., v. Ostra Mogila, cave Labirinta, 3.XI.1994, P. Beron leg.; 2 ♂, 4 ♀ ( ZMUC), Bulgaria, Sliven Distr., abandoned mine gallery in Karandila, 1.V.1991, PS leg.

Distribution. T. kotelensis is a Bulgarian endemic, recorded from several localities in Eastern Stara planina and Central Sredna gora mountains, where it is mostly found in non-cave habitats, though occasionally also in caves and abandoned mine galleries ( Vagalinski & Stoev 2007). It was recently reported for the vicinity of Shumen ( Bachvarova 2011).

Remarks. Jawłowski (1938) wrote that the type material of T. kotelensis was deposited in the Museum of Natural History in Krakow. It is now believed that most of this collection was destroyed during the Second World War (S. Golovatch, J. Wytwer, pers. com.). We herewith designate a neotype from nearly topotypic material found in the same area. Being in the best condition, the male from the vicinity of Shumen (ca 50 km away from the type locality, Beli vodi near Kotel) was designated as neotype.

Neotype description. 51+2+T body rings, l = 26.5 mm, h = 1.4 mm. 2 vertigial, 4 supralabral and 18 labral setae. Labrum tridentate. Antennomeres 2–5 subequal in length, ca two times longer than 6th; a group of long sensilla basiconica on antennomere 5, and a group of similar, but much shorter sensilla on antennomere 6. Gnathochilarium as usual, promentum 0.57 times as long as lingual plates, length to width ratio: 1.65; a row of 4 setae on each lingual plate. Lateral parts of collum visibly striated. Body rings somewhat vaulted. Prozonae mostly smooth, just with some scattered, very short and shallow grooves. Striation on metazonae rather sparse and shallow, with ca 7 striae in a square with sides equal to metazonal length just below ozopore level; a whorl of densely set setae, from 2/3 to equal to metazonal length, at metazonal hind margin. Ozopores about 1–2 times of their diameter behind pro-metazonal suture. Pleurotergum 7 ventrally forming short, broad, rounded protrusions, directed antero-mesad. Telson ( Fig. 4 ): preanal process moderately long, slender, sharply pointed, turned downwards, reaching the level of the longest anal setae; its whole upper surface covered with very long, scattered setae; subanal scale short, widely rounded, not protruding behind rear contour of anal valves; the latter without distinct row of shorter setae along caudal margins, setae rather gradually shortening towards the margins; several bumps (arrows in Fig. 4 ) near each margin. Leg-pair 1 compact, slightly converging hooks without tarsal remnants. Walking legs without adhesive pads. Tarsus of mid-body leg two times longer than tibia, apical claw just slightly shorter than tibia.

Gonopods: In situ fully concealed inside gonopodal sinus, opisthomere considerably longer than pro- and mesomere. Promere stout, ca as high as broad, distally narrowing, ending up with a broadly rounded apex bent posteriad; apical surface with rather weakly pronounced papillae; parabasal internal lobe (il) relatively small, with 3 apical setae; parabasal external lobe (el) more elongated, somewhat outreaching internal one, with 1 apical seta. Mesomere short and robust, with a squamate apical surface. Opisthomere with a distally convex posterior margin, without processes; basal spine (bs) mostly straight; intermediate lamella (il) very strongly developed, reaching just below velum; velum (v) unipartite, straight, pointed, with several minute spines (sp) at border with solenomere; solenomere (s) distally tapering, with a blunt tip; several minute spine-form filaments (sf) present in apical and caudal parts.
