A New Species

An illustrated description of morphology of Monocorophium insidiosum Crawford, 1937 from the Crimean coastal waters is given. In this work, 744 specimens from different locations and substrates of the Crimean coastal waters have been analyzed. The main specific parameters of species from the Crimean coastal waters are as follows: rostrum of males is about one half of first article of antenna I length, dactylus of gnathopod II is equipped with 2–4 additional spines along the inner side (both for males and females). Variability is observed in parameters of the following parts: first article of antenna I peduncle, fourth article of antenna II peduncle, inner side of gnathopod II dactylus, and outer sides of the outer and inner rami of uropod II. Morphological parameters of specimens from the Black Sea, the Mediterranean Sea (literature data), and the North America coast (Vancouver area, literature data) have been compared. Specimens from the Black Sea are morphologically similar, but have some differences from the North American ones. In particular, first article of antenna I peduncle of specimens from the North America have conical process (specimens from the Black Sea have rounded process); fifth article of antenna II peduncle is with proximal medial tooth (specimens from the Black Sea are without proximal medial tooth); and outer ramus of uropod II has medial spine (Mediterranean specimens are without such a spine). These differences should be taken into account when carrying out hydrobiological research.

The present work gives the results of the hydrobiological research of the middle course of the Bečva River in the river section between Valašské Meziříčí and Přerov, carried out in the years 2004 to 2007. Altogether, 65 taxa of macrozoobenthos were determined in the period 2000-2007 in the middle course of the Bečva River : Coelenterata (1 taxon), Oligochaeta (5 taxa), Hirudinea (3 taxa), Gastropoda (4 taxa), Isopoda (1 taxon), Amphipoda (2 taxa), Hydracarina (1? taxon), Ephemeroptera (7 taxa), Plecoptera (1 taxon), Odonata (3 taxa), Heteroptera (1 taxon), Megaloptera (1 taxon), Trichoptera (9 taxa), Coleoptera (3 taxa), Diptera (23 taxa). The number of zoobenthos taxa fell in the period 2004–2007 in comparison to period 2000–2002 from 51 taxa to 40 taxa. The decline of zoobenthos taxa was registered on study localities, as follows : Choryně (from 28 to 23 taxa), Hustopeče (from 27 to 25 taxa), Rybáře (from 35 to 28 taxa), Grymov (from 31 to 25 taxa). Average saprobity index of benthic community of the middle course of the Bečva River was 2.35. Average saprobity indices of monitored localities towards downstream were as follows: Choryně 2.41; Hustopeče 2.25; Rybáře 2.40; Grymov 2.34.
