: A new species of Elasmopus Costa, 1853 is described. The material examined was collected by SCUBA diving at the Itaipu and Boa Viagem beaches, municipality of Niterói, Rio de Janeiro state, Brazil. Elasmopus helenae sp.n. belongs to the castelloserrate group within the genus and is diagnosed by: antenna I accessory flagellum 2- or 3-articulated; gnathopod II with propodus subovoid and tapering distally, palm presenting two processes, medial one almost subquadrate, subdistal subtriangular but apically rounded; basis of pereopod V with posterior margin weakly serrate; basis of pereopods VI and VII with distal half of posterior margin castelloserrate; uropod I peduncle with two stout basofacial setae; and telson deeply cleft, each lobe apically truncate with an apicolateral and an apicomesial cusp.

: The variability of the species composition and community structure of coral ectosymbiotic invertebrates was studied using the reef-building coral Pocillopora verrucosa sampled from Dongsha Atoll (the northernmost atoll of the South China Sea). Overall, we discovered 61 symbiotic species, comprising 17 specialized obligate species and 44 generalists (facultative species and species with uncertain status). The total species richness, mean species number and mean abundance per colony were significantly higher in the lagoon than in the forereef, likely due to their respective temperature regimes. The lagoon is characterized by more frequent thermal anomalies than the forereef is, causing greater coral bleaching. This higher frequency of thermal stress apparently results in frequent renovations of coral-symbiotic communities following post-bleaching coral re-covery, which seem to be associated with the increased diversity of commensal fauna and, particularly, with the abundance of facultative symbionts. symbiotic communities from different environments of an isolated atoll: reef lagoon versus forereef // Invert.

. Only few millipede species were encountered in 2016 and 2021 in Pied flycatcher nests inside nest boxes set at a field station (60°46 ′ N, 32°48 ′ E) located within the subzone of middle taiga in Karelia, Russia. More species (5 vs 3) and higher abundance levels (123 vs 86) were observed in the cooler and rainy 2016 compared to the warmer and drier 2021, with the incidence of occurrence varying between ca 74% and ca 66%, respectively. The nests were dominated by Ommatoiulus sabulosus , while Leptoiulus proximus subdominated, during both years of monitoring. Together with the remaining few species of Diplopoda encountered in Pied flycatcher nests there, they can only be considered as purely opportunitic nidicoles. No obligate nidicoly in Karelian Diplopoda could be suggested, facultative nidicoly being common instead.
． 在2016年和2021年，在位于俄罗斯卡累利阿中部针叶林亚区内的一个野外站(60°46 ' N, 32°48 ' E)设置的巢箱内，只有少数千足虫物种被发现。与温暖和干燥的2021年相比，2016年较冷和多雨的年份观察到更多的物种(5比3)和更高的丰度水平(123比86)，发生率分别在约74%和66%之间变化。在两年的监测中，巢型以鹰嘴小眼为主，而近钩小眼次之。加上在斑姬捕蝇器的巢中遇到的其他几种双足类，它们只能被认为是纯粹的机会性昆虫。在卡累利阿二重足动物中没有专一性的裂口，而兼性裂口是常见的。

: The genus Pyramidula presents a Palearctic geographical distribution, being described in Spain four species not distinguishable from an anatomical point of view. In the present study, we compare our samples along with the previously recognized species P. rupestris , P. saxatilis , P. pusilla , P. cephalonica ; P. jaenensis , and P. chorismenostoma by means of molecular studies. Also, we compared P. jaenensis from the studied locality with P. rupestris according to the shell shape by means of geometric morphometric methods. The analysis of the Thin-Plate Spline graph showed that P. jaenensis presented an expansion on the growth to the first whorls and the apex, whereas the height of the body whorl was moderately contracted, while in P. rupestris the opposite was found. We found significant differences between both species based on shell shape. We also provide new information about morphological features that could be used in future studies of this genus attempting to stablish a baseline to test whether the Spanish species are cryptic species or not. The present study also extends the distribution of Pyramidula to Madrid, Spain,
金字塔属呈现古北的地理分布，在西班牙被描述为从解剖学的角度无法区分的四种。在本研究中，我们将我们的样本与以前认识的物种P. rupestris, P. saxatilis, P. pusilla, P. cephalonica进行了比较;用分子方法研究贾奈泊鱼和羽状瘤泊鱼。此外，我们还利用几何形态计量学的方法，根据壳的形状，比较了研究地点的贾颡鱼(P. jaenensis)与秘鲁颡鱼(P. rupestris)。薄板样条图的分析表明，日本稻向第一轮和顶端的生长呈扩张趋势，而体轮的高度呈适度收缩趋势，而鲁氏稻则相反。我们发现两种物种在外壳形状上存在显著差异。我们还提供了关于形态特征的新信息，这些信息可以用于该属的未来研究，试图建立基线来测试西班牙种是否为隐种。本研究还将皮拉米杜拉的分布范围扩大到西班牙马德里，

. Two new stygobiotic species of the genus Proasellus Dudich, 1925 (Crusta-cea: Isopoda), P . uallagirus sp.n. and P . irystonicus sp.n., are described from ground waters of Alagyr Gorge (North Ossetia – Alania, Russia). These samples are the first Proasellus representatives found in the Terek River basin and in the North Caucasus. Both species are morphologically close to the Transcaucasian species, especially P . linearis (Birstein, 1967), but can be easily distinguished by several characters. P . uallagirus sp.n. differs in shape of pleopodes, size ratio of pleopod exopodites and endopodites, and arming of internal surface of the pereopod I propodus. P . irystonicus sp.n. also differs in arming of pereopods I–VII dactiluses. The two new species can be easily distinguished from each other by armature of pereopod I–VII dactiluses, body size, and some characters of pleopods,
