Revision of the genus Hirsutiella
Schluger et Vysotzkaya, 1970 has been performed. A new species
H. alpina sp.n. is described from
southern Daghestan, Northern Ossetia, Krasnodar Territory and Turkey.
The new species is closely related to
H. steineri (Kepka, 1966) and
differs in the greater number of idiosomal setae (NDV=203—271 vs.
157—213), longer setae (Dmax=70—95 vs. 58—76, H=77—94 vs.
60—83) and legs (Ip=1236 vs. 1094, TaIII=113—133 vs. 90—112)
and larger scutum (AW=84 vs. 77, PW=101 vs. 95, SD=66 vs.
H. steineri and H.
llogorensis (Daniel, 1960) are reported from Russia (the
Western and Northern Caucasus) for the first time;
H. steineri is also reported for
the first time from Armenia, and H. hexasternalis
Kudryashova, 1998, from Chelyabinsk Province and Kazakhstan (Karaganda
Methods of multivariate analysis (factor and
discriminant analysis, multidimensional scaling) were used for
resolution of diagnostic problems in the genus
functions produced by the computer programme DIADIS (A.L. Lobanov,
Zoological Institute, Russian Academy of Sciences) allow reliable
identification of the representatives of the genus. Pattern of
characters variances in
Hirsutiella has also been
studied, and main relations between the characters are shown.
Dependence of the size parameters on climatic conditions, previously
reported by the author for the genus
Neotrombicula, is also revealed in
Hirsutiella. The species of the
H. llogorensis, has the
southernmost distribution and occurs at lowest altitudes.
H. steineri and H.
alpina are primarily alpine species, and H.
zachvatkini is a northern one, while
H. llogorensis inhabits mostly
forests in the foothills of southern European mountains and the
