Two articles on fossil Lestremiinae
(Diptera: Cecidomyiidae) in Rovno amber
(Perkovsky and Fedotova, 2004; Fedotova
and Perkovsky, 2004) are reviewed
and discussed. As a result, the
following gall midges species are considered
Lestremiinae incertae sedis: +
Aprionus admirandus Fed., + Conarete
laesus Fed., + Heterogenella sparsa
Fed., + Micromyia convoluta Fed., +
Peromyia autonoma Fed., + Peromyia
miranda Fed., + Peromyia sukachevae
Fed., + Peromyia zherikhini Fed. (all in
Perkovsky and Fedotova, 2004), +
Campylomyza falciformis Fed., + Campylomyza
superposita Fed., + Neurolyga
declinata Fed., + Strobliella appropinquata
Fed., and + Strobliella capitata
Fed. (all in Fedotova and Perkovsky,
2004).

Based on the study of more than 300
isophlebiid specimens from several Late
Mesozoic sites in eastern Transbaikalia
(Ukurei, Tergen’, Glushkovo, and Byankino
formations), new genera and
species are described: Xeta olovica, Dahurium
draco, and Sinitsia sophiae. The
insect-bearing deposits are dated Late
Jurassic according to analysis of their
odonatofauna.

New taxa of uncertain position within
the infraclass Polyneoptera (Gryllomantidae
fam. nov.: Gryllomantis gen. nov.,
Lower Cretaceous; Mantoblattidae fam.
nov.: Mantoblatta mira gen. et sp. nov.,
Upper Cretaceous) and within the order
Dictyoptera (Pseudojantaropterix gen.
nov., Lower Cretaceous) are described.
The superfamily Umenocoleoidea of uncertain
position within the latter order is
discussed on the basis of new information
on Jantarimantidae and some other
Cretaceous Dictyoptera.

Juvenile development of the Middle
Cambrian agnostid trilobite Pentagnostus
proanabarensis Fedoseev, 1999 is
studied. A sequence of eight juvenile
stages is defined based on changes in
morphology and measurements. Three
of them belong to meraspid degree 0,
another three refer to meraspid degree 1,
and two represent early holaspid stages.
Neither the frequency distribution of the
length of cephalons and pygidia nor the
length-width scatter diagrams give clear
clusters of molts; the number of juvenile
molts can be estimated through the
analysis of the posteroaxis length distribution.
Thus, the measurements and
morphology of some juvenile pygidia
with vestiges of the pleural and postaxial
furrows allow reconstruction of the
number of segments during individual
growth. At the initial stage of development,
the pygidial axis of P. proanabarensis
probably had four segments,
