Two New Species of Mites of the Genus Scutacarus (Acari, Heterostigmata, Scutacaridae) from Ukraine.
Khaustov A. A. — Two new species of mites of the genus Scutacarus Gros, 1845 of spengleri-group:
S. yuliae Khaustov, sp. n. and S. livshitsi Khaustov, sp. n. are described from Ukraine.
Ke y wo r d s: Acari, Scutacaridae, Scutacarus, new species, Ukraine.
S. Mahunka (1974) described a unique species of the genus Scutacarus Gros, 1845
(Acari, Heterostigmata, Scutacaridae): S. spengleri with unusual position of setae 3b
which situated far posteriorly to setae 3a and close to apodemes 4. E. Ebermann (1986)
found single specimen of S. cf. spengleri in Italian Islands, but noted that it differs from
S. spengleri by the length of dorsal setae. During my study of scutacarid-fauna of
Ukraine I found two more species with similar unique position of setae 3b. Based on
this character I create in the genus Scutacarus a new spengleri-group which now inclu-
des 4 species: S. spengleri Mahunka, 1974 (type species), S. cf. spengleri Ebermann,
1986, S. yuliae Khaustov, sp. n., and S. pseudospengleri Khaustov, sp. n. The purpose
of this paper is to give a detailed description of two new species of mites of the genus
Scutacarus of spengleri-group from Ukraine.
The terminology follows that of E. E. Lindquist (1986). All measurements are
given in micrometers (mkm) for holotype. Type material is deposited in the collection
of the department of Acarology, Shmalgausen Institute of Zoology, Kyiv, Ukraine.

tral setae: 1a 40, 1b 36, 2a 38, 2b 24, 3a 33, 3b 37, 3c 47, 4a 37, 4b 98, 4c 62, ps1 36,

in parenthesis). Tibiotarsus with well developed claw. Solenidia 1 14 < 2 15 > 1 8 =
= 2 8. Solenidion 1 finger-shaped. Solenidion 1 baculiform. Solenidia 2 and
2 uniformly thin. Seta d of femur I spine-like. Leg II: Tr1–Fe3–Ge3–Ti4(1)–Ta6(1).
Tarsus with sickle-like padded claws. Solenidion 12 finger shaped. Leg III:
Tr1–Fe2–Ge2–Ti4(1)–Ta6. Claws of same shape as on tarsus II. Leg IV (fig. 3):
Tr1–Fe2–Ge1–TiTa7. Tibiotarsus slightly longer than its width.
Ma l e a nd l a r v a. Unknown.
D i f f e r e n t i a l d i a g no s y s. The new species is most similar to S. spengleri], but
differs by setae e more than twice shorter than h2 (e as long as h2 in S. spengleri), by
setae c1 much shorter than f and h1 (c1 about as long as f and h1 in S. spengleri), and
by position of setae 3b which situated distinctly anteriorly to ap4 (bases of 3b joined
with anterior margin of ap4 in S. spengleri).
