The new strain shares several morphological characters of this morphospecies, in particular, cell coat structure and the presence of unique “trichocyst-like bodies” in the cytoplasm. The studied strain branches in one of the clades of marine Vexillifera species, with the unnamed Mediterranean Vexillifera strain K9 as its closest relative. Unfortunately, the type strain of V. armata was lost before any molecular data were obtained. Therefore, no information is available on this species for molecular comparison. The studied strain was isolated from the habitat geographically very distant from the type one. The type strain of V. armata was estuarine, while the new strain was isolated from the lower sublittoral benthos and appears to be stenohaline based on the results of an experimental study. It also showed some elusive morphological differences that may be regarded as intraspecific variation. Although currently known extent of cryptic speciation in the naked lobose amoebae is relatively high, the differences between the studied strain and V. armata may be too subtle to warrant a description of a separate species. Therefore, we conclude that the new strain should be identified as Vexillifera cf. armata. Re-isolation of V. armata from its type locality is highly desirable to evaluate a degree of molecular variability within this morphospecies.

This genus is characterized by a global distribution and has considerable value in the bait industry worldwide. Therefore, the correct delimitation of species is important not only for consideration of its evolution, but also for culturing species from this genus. Marphysa sanguinea (Montagu, 1813) represents a complex of species and its global distribution is not clearly defined. Herein we describe a new species, Marphysa aegypti sp.n., belonging to the M. sanguinea group from the coastal waters of Egypt. This species, which has previously been reported as M. sanguinea, has a high commercial value as it is collected and vastly used by fishermen in Egypt. In our study, we used both molecular (COI barcoding region) and morphological species identification. Our results confirm that this polychaete, which is a common inhabitant of Egyptian coastal waters (i.e., Mediterranean Sea, Red Sea and the Suez Canal), is a distinct species. Our findings further support the view that the polychaete fauna of Egypt needs taxonomic revision. Determination of the polychaete species of Egypt, similarly to other regions of the world, is based on identification keys developed for Northern European species and lacks thorough morphological comparisons. Therefore, all previous records of M. sanguinea in coastal waters of Egypt should be reconsidered as being indeed M. aegypti sp.n.

Unlike other siphonophores the members of the family Rhodaliidae are benthic. Almost all species of this family are poorly known, and most are known from very few specimens, some of which were collected more than 100 years ago and newer recorded again. Till now rhodaliids were not known from NW Pacific at depths greater than 1000 m. In the present paper we describe a brief history of the family, the morphology of the recorded here specimens basing on photo and video data, and provide a list of all described species of the family with short comments on each.

It is distinguished from them by segmental fusion pattern of the antennule, the armature of the antennary exopod and the maxillule, and the length and armature of the caudal ramus.

These glands produce the mucus for a gelatinous tentlike structure in which the eggs are fertilized and attached to the pleopods. Long-term observation of females of the sexually reproducing slough crayfish, Procambarus fallax, kept in captivity revealed that the glair glands developed in late winter and late summer of each year independently of the presence of males. In mated females, they secreted their contents shortly before spawning. In contrast, unmated females of slough crayfish did neither empty their glair glands nor spawn. Their glands persisted for an unusually long period of time and disappeared only during the next moult. Apparently, slough crayfish females use information on sperm availability to either spawn or save the resources. Females of marbled crayfish, Procambarus virginalis, a parthenogenetic all-female descendant of slough crayfish, developed glair glands in approximately the same periods of the year but generally spawned despite of the lack of males. These findings suggest that in marbled crayfish glair secretion and spawning is decoupled from mating. Therefore, the species pair P. fallax and P. virginalis seems to be particularly suitable to investigate the regulation of spawning in freshwater crayfish. How to cite this article: Vogt G. 2018.
