Introduction
Six species of genus Arrhopalites Bo�rner, 1906 were recorded from the caves of Ukrainian (Eastern)
Carpathians during our biospeleological investigations (Vargovich, 2000). One of them, collected from
Dovharunya cave/adit, on the left bank of the river Tisa in the Marmarosh mountains, is the second new
species from the region and described here.
Head chaetotaxy is given according to the nomenclature of Christiansen (1966). Setae names of ti-
biotarsi, dens and partly of antennae are given following Nayrolles (1988, 1990, 1991). Nomenclature of
Lawrence shown in K. Christiansen, P. Bellinger (1998) for setae of anogenital abdominal segment is used.

Ma l e. Maximum body length 0.85 mm. Head relatively shorter than in female.
Antennae 1.8–1.9 times as long as head diagonal. Ant. IV with with 5 subsegments, or
with 6 subsegments in case of separation of BA setal whorl. Chaetotaxy of anogenital
abdominal segment (fig. 2, 10) differs from such in female by lesser number of setae
and by shape of C-setae, not broadened in male.
V a r i a b i l i t y. Lengths proportions of antennal segments I : II : III : IV = 1 :
1.8–2.2 : 2.7–3.2 : 7.1–8.3. Number of setae on whorls of Ant. IV may slightly vary.
Empodia of fore and mid leg sometimes with corner inclination looking like indistinct
corner tooth. Empodium of hind leg with a very small up to absence corner tooth.
Number of tenaculum apical setulae (2 or 1) apparently varies even inside the same
micropopulation. Some specimens show incomplete posterior dens chaetotaxy (variable
setae marked in brackets in tabl. 1). In single case female dens with 3, 2, 1, 1, 1 ante-
rior setae — an example, when important diagnostic feature shows variability. In one
case seta C4 of female anogenital segment is forked.
D i f f e r e n t i a l d i a g no s i s. Arrhopalites kristiani sp. n. belongs to the assembling
of species with combination of characters: (1) presence of single spine on dens and
(2) absence of basal swelling on Ant. III. Twelve taxa with such condition were de-
scribed: A. boneti Stach, 1945, A. subboneti Cassagnau & Delamare, 1953, A. giovannen-
sis Cassagnau & Delamare, 1953, A. cochlearifer dudichi Loksa & Rubio, 1966 and
A. aggtelekiensis buekkensis Loksa, 1969 from Europe; A. clarus Christiansen, 1966,
A. sacer Christiansen & Bellinger, 1996, A. ater Christiansen & Bellinger, 1998, A. sapo
Zeppelini & Christiansen, 2003 and A. sextus Zeppelini & Christiansen, 2003 from
North America; A. gul Yosii, 1966 from Korea and A. uenoi Yosii, 1956 from Japan.
Such combination as presence of: elongated, thin and untoothed claws of legs +
untoothed empodia of fore and mid leg + strongly swollen C-setae of female anogeni-
tal segment + presence of 5 subsegments on Ant. IV + narrowed tip of mucro distinct-
ly separates A. kristiani sp. n. from all mentioned species (tabl. 2).
B i onomy. 11 specimens were collected from lower level of cave/adit (natural and
anthropogenic genesis) from the pool surface. This part of cave is stopped by stony
gorge and cold draught is present in winter: so connection with surface is possible. Only
