Introduction
The genus Cosmochthonius Berlese, 1910 has cosmopolitan distribution. Its type species, C. lanatus
(Michael, 1885) was originally described from England. Most of Cosmochthonius species are known from the
Palaearctic Region and their diversity is especially large in the Mediterranean Area A new species was found
in the costal area of the South-Eastern Crimea (Ukraine) and, later, in two different places of Eastern
Mediterranea, in Turkey (Marmaris) and Greece (Rhodes).
Methods
In the description below, we follow the terminology of morphological and chaetotaxic notations of
Grandjean (1962) and Mahunka & Zombori (1985). The specimens were studied and photographed with a
scanning electron microscope (JEOL JSM–5200) equipped with digital image recording system for SEM
(SemAfore 4). The drawings were made with a camera lucida attached to a compound microscope.

I n t e g umen t. Dorsal side of
body, except the dorso-sejugal sutu-
re, covered by thick cerotegument
with small granules, irregular pores
and big holes, and having reticulate
appearance (fig. 2–5). Cerotegu-
ment is denser on strips above trans-
versal sutures. Cuticle on dorsal side
of body with foveolae, whereas cuti-
cle of dorso-sejugal region with thin,
longitudinal lines.
P r odo r s um (fig. 6–10) cove-
red by continuous cerotegument, the
densist on margin of rostrum. Ros-
trum with 5–7 longitudinal apertures
and blunt apex without dents.
Narrow transversal cuticular
ridge in the base of prodorsum be-
tween bothridia is covered by cero-
tegumental “collar” with straight back
border.
Rostral setae (ro) on tubercle, phylliform, long and thick, with bi- or trifurcate
bristles. Lamellar setae (le) biramous, lateral flatten, with bi- or trifurcate bristles.
Posterior branch of setae le short, whereas anterior branch long and wide. Setae ro and
le with thin acute angle tops. Interlamellar setae (il) phylliform, long, lateral flatten,
with bi- or trifurcate bristles. Anterior exobothridial setae (exa) dorsoventrally flatten,
almost round, with folds and spinose, whereas posterior exobothridial setae (exp) short
and penicillate. Sensillus (ss) long (60.4 mkm), its wide head longer than stalk and cov-
ered with some longitudinal rows bristles on the upper and lateral sides and central row
bristles on the bottom.
No t o g a s t e r (fig. 1–4). All plates of notogaster (Na, Nm1, Nm2 and Py) covered with
robust cerotegument just as prodorsum. First plate Na with four pairs of setae ( c1, c2, c3, cp),
second plate Nm1 with two pairs of setae, d1 and d2. Setae c, d and cp extended, phylliform,
thick in the base and triangular in cross-section. Dorsal surface and margins of setae covered
by small spines.
Insertion points of setae c1, c2 and c3 situated on the same level along frontal margin of
plate Na, and the setae cp in postero-lateral angles of this plate. Distances between c1—c1
(20.0) < c1–c2 (21 mkm) < c2–c3 (22.5 mkm). Setae c1 (48.7 mkm) < c2 (53.5 mkm) < c3
(60.2 mkm). Setae cp particularly long (72.8 mkm), reaching over insertion points of setae
h3 on plate Py. Insertion points of setae d covered by posterior part of Na. Setae d1 (18.5 mkm)
< d2 (21.6 mkm) and d1–d1 < d1–d2.

Bipectinate setae e and f situated on narrow, transverse intercalar sclerites between the
plates Nm1–Nm2 and Nm2–Py, accordingly. Secondary setae shorter than a width of a mid-
dle rib. Their size and number decrease toward the top. The middle rib covered by squamose
spines (fig. 11–12).
Setae e1 (142 mkm) and e2 (133mkm) longer than f1 (126.9 mkm) and f2 (120 mkm).
The distance e1–e1 (18.5 mkm) < e1–e2 (20.6 mkm), whereas f1–f1 (37.1 mkm) > f1–f2
(27.7 mkm). The setae h and p similar with setae ro, phylliform, long and thick, with bi- and
trifurcate bristles. The setae h1–3 and p1 close to margin of Py, whereas the setae p2 and p3 on
ventral side.
Ven t r a l s i d e (fig. 14–17). Ventral plates and anal region covered with strong ce-
rotegument, similarly to notogaster, and genital plates covered by thinner, not clearly
defined wax layer. Epimeral region and gnathosoma sporadically with thin cerotegument.
S ub c a p i t u l um an a r t h r i c. Hypostomal (h) setae long, slender, biramose,
reaching from posterior part of mentum to base of gena. Median infracapitular setae
similar to setae h reaching to rutellum. Setation of pedipalps: 0–2–1–3–11.
Epimeral setae long, thin and biramose Epimeral formula (I–IV): 3–2–3–4.
Genital plate with 10 setae, similar to the epimeral setae. Six genital setae close to
medial line of plate and four setae farther off. The anal and aggenital plate with 4 setae.
All anal setae densely ciliate, equal size whereas adanal setae ad1 longest and ad4 shortest.
L e g s. Setation (trochanter to tarsus): I (0–5–5–6–19), II (1–6–5–6–17), III
(2–3–4–4–15), IV (2–3–4–4–14). Solenidia (genu-tibia-tarsus): I (0–1–1), II
(0–1–1), III (0–1–0), IV (0–1–0). Claws (I–IV): 2–3–3–3. The dorsal and lateral
setae phylliform and wide with two or three lines by small spines (fig. 13).
D i a gno s i s. Cosmochthonius zanini sp. n. belongs to the reticulatus-foliatus species
group, which is characterised by the thick cerotegument; it differs from other Cosmo-
chthonius species by the wide, phylliform setae c, d and cp, very long setae cp (extend-
ing to insertions of setae h3) and by the narrow, straight “collar” between bothridia.
R ema r k s. The specimens from Rhodes Island (Greece) differ from those collect-
ed in Crimea by longer secondary setae on the setae f1, whereas the specimen from
Turkey differs by longer secondary setae of f1 and f2 (fig. 3–4).
E t ymo l o g y. We dedicate the new species to Alexander Zanin (Ukraine), who
assisted and encouraged our work.
