Figs. 1–6

Measurements. Body length: 296–320 (holotype: 300), body width: 124–140 (holotype: 134). Six specimens were measured.

Prodorsum ( Fig. 1 ). Rostrum rounded. Rostral setae 22 in length, arising on the dorsal surface of rostrum, curved inwards, with one cilia. There is a protuberance between the rostral setae. Lamellar setae 6 in length, arising near the costulae. Interlamellar setae 10 in length, on a pair of cristae in the interbothridial region. Distance between lamellar and interlamellar setae shorter than that between rostral and lamellar setae. Costulae in the shape of two inverted ‘V’, transcostula well developed. One pair of tubercles outside of the costulae. Sensilla fusiform, with several distinct barbs.

Notogaster ( Fig. 1 ). Elongate oval, 234 in length, its anterior and posterior margins conspicuously narrowed; anterior margin reaching to the level of anterior edge of bothridia. Crista absent. Ten pairs of notogastral setae; seta c2 20 in length and smooth.

Ventral side ( Fig. 2 ). Mentum 26 in length, 40 in width. Setae m 10, setae a 12 in length. Epimeral setal formula 3-1-3-3. Epimeral regions 3 and 4 with polygonal network, but on epimere 2 polygonal network is visible only in median part. Genital plate 34 in length, 32 in width, with four pairs of setae. Anal plate 40 in length, 44 in width, with two pairs of setae. One pair of aggenital and three pairs of adanal setae. Distance between genital and anal plates 72. Lyrifissures iad situated in para-anal position. Adanal setae ad 1 in postanal, ad 2 in para-anal and ad 3 in preanal positions.

Legs ( Figs. 3–6 ). All legs monodactylous, setation of leg segments is given in figures 3–6.

Material examined. YÇMP-370, soil from Pinus nigra and Quercus spp. forest, N 39°48.137’, E 034°48.663’, 1569 m, 18 Apr 2006, holotype and one paratype; YÇMP-363, as for the previous sample, N 39°48.140’, E 034°48.666’, 1563 m, 18 Apr 2006, one paratype YÇMP-379, as for the previous sample, N 39°48.122’, E 034°48.653’, 1577 m, 18 Apr 2006, three paratypes (one of them in the collection of L. S. Subias, Spain).

Etymology. Specific name yozgatensis is named after the locality, Yozgat, where the present new species was found.

Remarks. This new subspecies resembles Moritzoppia unicarinata clavigera described by Hammer (1952) from Northern Canada. However, it can be distinguished from the latter species by the following features: 1) there is a protuberance between the rostral setae in the new species (there is no protuberance between the rostral setae in M. unicarinata clavigera ); 2) lamellar setae arising near the costulae in the new species (lamellar setae arising at the distal end of the costulae in M. unicarinata clavigera ); 3) anterior margin of the notogaster reaches to the level of anterior margin of the bothridium in the new species (anterior margin of the notogaster reaches to the level of posterior margin of the bothridium in M. unicarinata clavigera ).

Colloff & Seyd (1991) redescribed M. clavigera by using syntypes. They stated that the translamella is absent the specimens they examined, although Hammer (1952) mentions that often the middle portion of the translamella is absent, or it is tripartite, and she shows it as complete in her figure. However, from the translamella point of view, our samples resemble the Hammer’s figure ( Hammer 1952). In the description, we used the transcostula instead of the translamella.
