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.
Time and Heritage
As a historian studying what can be considered a form of intellectual history, I have slowly come to adopt Michel de Certeau’s observation made at the end of the 1980s that ‘objectifying the past, for the last three centuries, has undoubtedly left unconsidered time within a discipline that has continued to use it as a taxonomic instrument’. To a certain degree, time has become commonplace for the historian who has preserved or instrumentalized it. It is not considered because it is inconceivable, but because we do not think of it or, more simply, we do not think about it. As a historian attempting to pay attention to the time I’m living in, I have thus, like many others, noticed the swift development of the category of the present until it has become obvious that the present is omnipresent. This is what I refer to here as ‘presentism’.
