: Brachiopoda is a phylum of marine benthic animals belonging to the Spiralia clade; however, their relationships with other spiralians and the origin of their unusual body plan remain unclear, even with the application of molecular genetics methods. One of the major ideas on the origin of the brachiopod body plan is the “brachiopod fold” hypothesis, fi rst proposed in 1991, and much developed since then. In its present content it implies that brachiopods derived from metameric ancestor by reduction of the number of metameres, and folding onto the ventral side. Thereby both valves – “dorsal” and “ventral” – turn out to be actually dorsal. In the present study, we discuss the pros and cons of this hypothesis, and provide some additional data on the anatomy of Novocrania anomala adults, which are consistent with the “brachiopod fold” hypothesis. We have found traces of ancient “folding” in the form and co-localisation of lateral mesenteries and metanephridia. We also propose a general scheme of the evolution of the craniiformes’ body plan.

. A new species of the stygobiotic pond slater, Proasellus precaspicus sp.n. (Crustacea: Isopoda), was described from groundwater of the Samur River in the Samursky National Park (Southern Dagestan, Russia). This is the first finding of the genus from the territory of the East Caucasus and Caspian Sea coast. The new species is morphologically close to other species known for the Caucasus region, especially to those described from North Ossetia. However, it can be easily recognized due to the combination of the following characters: inner margin of dactylus of pereopodes I with five to nine robust stiff setae; inner margin of dactylus of pereopodes II–VII with single robust stiff spiniform seta; inferior margin of propodus of pereopodes I with three long robust stiff setae; pleopod I with single coupling hook in retinacula of pleopod I. The new species inhabits various springs in the sources of small rivers and streams, as well as hyporheic waters.

: Cuttlefishes store their tentacles in the pockets, which are open depressions in the anteroventral surface of the head between the bases of arms III and IV. When cuttlefishes hunt prey, they rapidly extend their tentacles from the pockets towards the prey, catch it using tentacular clubs, retract the tentacles to the pockets, and then hold it to their mouth using their arms. Tentacle storage in the pockets is important for hunting. However, the arrangement of the tentacles in the pockets remains unknown. In this study, I report the arrangement of tentacles in the pockets of pharaoh cuttlefish Sepia pharaonis (Ehrenberg, 1831) and golden cuttlefish Sepia esculenta (Hoyle, 1885) by morphological observation. Two patterns for keeping the tentacles in the pockets were observed. In the first pattern, tentacular clubs were located outside the tentacle pocket openings. The curling of tentacular stalks was less complex than that of the second pattern. In the second pattern, tentacular clubs were completely retained inside the pockets. The curling of the tentacular stalk was more complex than that of the first pattern. In both patterns, the tentacular stalks first turned from the origin towards the oral side and then curled with twisting from the oral side to the aboral side in the pockets. We observed that tentacular stalks did not tangle. This result contributes to understanding the basic morphology of tentacular storage in cuttlefish pockets. Possible causes for the differences between the two patterns are discussed.

. Cross-predation is an important event that may influence prey–predator dynamics, especially in arid and semiarid ecosystems. In this study, we report four predation events involving lizards and scorpions from different sites in the Brazilian seasonal dry tropical forest. In three of these events, the lizard acted as the predator, while in one event, the scorpion was the predator. Body size played a determining role when lizards were the predator of the scorpion, with larger vertebrates feeding on the arachnids. In contrast, when the sizes were similar, the scorpion acted as the predator of the lizard. Our findings suggest a complex relationship between lizards and scorpions in the Brazilian seasonal dry tropical forest.

: A comparative study of the structure and localization of sensilla on the palps of caddisflies from the genus Rhyacophila , the family Rhyacophilidae, was carried out for the first time. The structure of maxillary and labial palps in 15 species of the genus Rhyacophila was studied by scanning electron microscopy. Seven types and two subtypes of sensilla were found on these head appendages: pointed long trichoid sensilla, blunt chaetoid (gustatory) sensilla (two subtypes), campaniform sensilla, thick basiconic sensilla, petaloid sensilla, leaf-like pseudoplacoid and mushroom-like pseudoplacoid sensilla. The size of chaetoid and pointed trichoid sensilla on palp segments decreases towards the palp apex. Pseudoplacoid sensilla, as a rule, are found only on the terminal segments of the labial and maxillary palps, and in some species they completely disappear. Terminal segments of both pairs of palps have sensory fields formed by aggregations of petaloid sensilla. Apical sensory complexes are localized at the apical end of the maxillary and labial palps. At the top of these sensory areas there is a thick basiconic sensilla, on the lateral surface of the sensory complex there are rudimentary basiconic sensilla. The structure and localization of palpal sensilla, apical sensory complexes, and sensory zones with petaloid sensilla can be used for taxonomy purposes
