We provide morphological and genetic evidence to establish the presence/occurrence of Alpheus angulosus, Alpheus buckupi, and Axianassa australis on the coast of Maranhão, Brazil. The specimens were collected in December 2019 by actively searching the estuaries and rocky shores of São Luís Island, northeast of Brazil. In addition to morphological analyses, two mitochondrial genes were obtained (Cytochrome C Oxidase I and 16S), and a phylogenetic analysis was conducted to verify the specimens’ identity. Accurate identification is an essential tool to obtain reliable information about the occurrence of the species and thus help assess biodiversity in a highly diverse region. These finding also serve to stimulate future studies in poorly studied areas as well as set a baseline for biodiversity conservation and preservation strategies.
我们提供形态学和遗传学证据，以确定Alpheus angulosus、Alpheus buckupi和axanassa australis在巴西maranh海岸的存在/出现。这些标本是在2019年12月通过积极搜索巴西东北部s o Luís岛的河口和岩石海岸收集的。除了形态学分析外，还获得了两个线粒体基因(细胞色素C氧化酶I和16S)，并进行了系统发育分析以验证标本的身份。准确的鉴定是获得有关物种发生的可靠信息的必要工具，从而有助于评估高度多样化地区的生物多样性。这些发现也有助于在研究不足的领域促进未来的研究，并为生物多样性保护和保护策略设定基线。

Specimens of lophogastrids were collected off Chile, including four first records: Ceratolepis hamata G.O. Sars, 1883 in the vicinity of Easter Island, Eucopia unguiculata (Willemoës-Suhm, 1875) the Juan Fernández Archipelago, Gnathophausia zoea Willemoës-Suhm, 1873 off Concepción, and Neognathophausia ingens (Dohrn, 1870) off Valparaíso. Additional records were also obtained for Chile for four species: Eucopia australis Dana, 1852, Eucopia grimaldii Nouvel, 1942, Fagegnathophausia gracilis (Willemoës-Suhm, 1875), and Paralophogaster sp. Based on these records, lophogastrids are now represented off Chile, in the southeastern Pacific, by nine species.

The present study provides some parameters of the population biology of Charybdis (Charybdis) hellerii (A. Milne-Edwards, 1867), an invasive swimming crab inhabiting the estuarine portion of the Sergipe River, northeastern Brazilian coast. Samplings were carried out monthly from July 2015 to June 2016 with baited traps. The species was the second most abundant caught organism and its relative abundance ranged over the time from 11 to 59%. Sex ratio was 1:1 and all individuals were morphologically mature. Males were bigger than females. Ovigerous females were observed year-round and the smallest one was 31.35 mm carapace width. These findings show that the population is well established on the Sergipe coast. The entire distribution, and possible impacts, of C. (C.) hellerii on local environments need to be evaluated in further studies.

Abstract Neocaridina davidi (Bouvier, 1904) is a shrimp commonly used in aquaculture throughout the world. It is an exotic species in several places. We investigated the preference of N. davidi for four types of shelter (rock, Vesicularia sp., Egeria sp., and wood) and its nictemeral activity variation. Individuals were divided into three experimental groups: males, non-ovigerous females, and ovigerous females. They were placed in tanks with the four shelter types and observed every 3 hours for 72 hours. Neocaridina davidi presented cryptic behavior with 82.1 ± 8.69% of individuals sheltering per observation. Sheltering was higher during the daytime (88.8 ±5.54%) than at nighttime (75.4 ± 5.53%). Vesicularia sp. was the most used shelter followed by wood. The least used shelter type was a rock. Swimming and walking were more frequently observed at nighttime, especially for ovigerous females. We have demonstrated the importance of providing shelter for the maintenance of N. davidi in tanks as well as its higher activity at nighttime.
