The fauna of barklice (psocoptera) of the Southern Urals
Based on the material collected in 2014 in the Southern Ural State Nature Reserve and adjoining territory, 25 psocopteran species belonging to 17 genera of 8 families are recorded for the first time for the Republic of Bashkortostan. Among these, 20 species, 12 genera, and 4 families are new to the fauna of the Southern Urals, and two species are new to the Russian fauna.
Chromosome numbers in eight species of Palaearctic Psocoptera (Insecta)
Karyotypes of eight Psocoptera species are reported for the fi rst time. In Va- lenzuela oyamai (Enderlein, 1906) (Caeciliusidae), Peripsocus golubae Lienhard, 2006 (Peripsocidae), Trichopsocus dalii (McLachlan, 1867) (Trichopsocidae), Hemineura dispar Tetens, 1891 (Elipsocidae), and Amphigerontia contaminata (Stephens, 1836) (Psocidae) 2n = 16 + XX/X0. In Elipsocus moebiusi Tetens, 1891 (Elipsocidae) 2n = 12 + XX/X0. Neopsocopsis hitricornis (Reuter, 1893) (Psocidae) has 2n = 14 + XX/ X0, and Kolbia quisquiliarum Bertkau, 1883 (Amphipsocidae) has 2n = 14 + neo-XY/ XX. In addition, three seminal follicles per testis have been established in V. oyamai, H. dispar, A. contaminata, and N. hitricornis and one follicle in P. golubae and T. dalii. All the data available on psocopteran karyotypes are tabulated and shortly reviewed.
The variability of the chromosome numbers in Psocomorpha (Insecta, Psocoptera)
Abstract Karyotypes of 10 species of Psocoptera of 8 genera and 5 families of the advanced suborder Psocomorpha are reported for the first time. In Stenopsocus aphidiformis End. 2n=23, 24 (22A + X0/XX); in Lachesilla pedic-ularia L., L. tanaidana Roesler, Ectopsocus briggsi McLachl., Elipsocus pumilis (Hagen), Amphigerontia bifasciata (Latr.), Sigmatoneura kolbei End., and Trichadenotecnum sexpunctatum L. 2n=17,18 (16A + X0/XX); in Amphigeron-tia jezoensis Okam. 2n=15, 16 (14A + X0/XX), and in Loensia variegata (Latr.) 2n=13, 14 (12A + X0/XX). The karyotype variability in suborder is estimated. The pathways of the karyotype evolution in Psocomorpha are discussed.
