The research has been carried out in Dien Bien Province (Northwest region of Vietnam) from 2013 to 2019. This is the very first checklist of the terrestrial snails of Dien Bien Province. The checklists provide databases and helps to understand the biodiversity richness of the particular region of country. As such, they also open trends for further research priorities. Altogether 80 species and subspecies of terrestrial snails belonging to 17 families, 49 genera are listed with 5 genera (Lagocheilus, Metalycaeus, Scabrina, Laotia, and Moellendorffia) and 36 new species recorded for Dien Bien Province

A new species of Scutalus Albers, 1850 (Gastropoda: Bulimulidae), Scutalus chango sp. n., is described from a coastal area of northern Chile. Empty shells of this new species were found buried in sand and under boulders and rocks in the foothills of the Chilean Coastal Range at Paposo, Región de Antofagasta. This new species is distinguished from all other Chilean terrestrial snails by its slender shell with a flared and reflected aperture, and by the presence of a columellar fold. This is the first record of Scutalus in Chile, and the southernmost record for this endemic South American bulimulid genus. The presence of this species in Paposo highlights the need for further research and for conservation guidelines in coastal areas of northern Chile, which have comparatively high levels of biodiversity and endemism.

Aromobates is a genus endemic to the northern Andes of Colombia and Venezuela. Limited information is available aboutthis genus diversity, current distribution, and taxonomic characterization. Here, we describe three new species of Aromo-bates from the Andes of Venezuela. We provide the most comprehensive phylogeny of Aromobates to date and taxonomicnotes on Aromobates saltuensis Rivero and A. inflexus Rivero. We also discuss the limitations of the current molecularand morphological diagnosis of Aromobates. Finally, we comment on the conservation status and research priorities for this genus.

Desmodium amplistipulaceum, a new species from the evergreen tropical forest of La Sepultura Biosphere Reserve, Chiapas, is described and illustrated. Morphologically it is very similar to Desmodium helleri, but it differs from this by persistent and widely ovate stipules; inflorescences in simple racemes and slightly hirsute sessile loments with 4 or 5 articles. It includes a morphological description, map of distribution and comparative photographs of the calyx, trichomes of calyx and gynoecium and stigma for both species, as well as an identification key to differentiate all the Desmodium species from La Sepultura, Chiapas.

There are 68 known species of Hyalella worldwide, with 23 occurring in Brazil. The state of Rio Grande do Sul, Southern Brazil, has the largest diversity of the genus in the country, with nine species recorded. The current study aimed to describe two new species of Hyalella from state of Rio Grande do Sul, both of them in the Northwest region of the state, one found in a small spring and another in an artificial pond. Hyalella georginae n. sp. presents several clusters of simple setae on antenna 2, maxilliped very slender, gnathopod 2 dactylus not reaching the lobe of propodus, pleopods rami with short plumose setae and a peculiar pattern of setae on uropods and telson. Hyalella gauchensis n. sp. presents antenna 2 with few setae, maxilliped very slender, gnathopod 2 dactylus reaching the lobe of propodus and pleopods rami with long plumose setae. From this work, the number of Hyalella species found in Brazil increases to 25 and 70 for the genus.

Abstract Lithobius (Ezembius) laevidentata sp. n. (Lithobiomorpha: Lithobiidae), discovered from Barkol Kazak Autonomous County, Hami City, Xinjiang Uygur Autonomous Region, Northwest region of China, is described. Morphologically it resembles L. (E.) bilineatus Pei, Ma, Zhu & Gai, 2014. from Guangxi Zhuang Autonomous Region, China, but can be readily distinguished from the latter by 8–10 ocelli arranged in 3 irregular rows, Tömösváry’s organ subequal in size to the adjoining ocelli, female gonopods with 3–4 spurs, and the terminal claw of the third article of female gonopods simple. A key to Chinese Lithobius (Ezembius) species is presented.

Abstract. Background: Suicide can have a lasting impact on the social life as well as the physical and mental health of the bereaved. Targeted research is needed to better understand the nature of suicide bereavement and the effectiveness of support. Aims: To take stock of ongoing studies, and to inquire about future research priorities regarding suicide bereavement and postvention. Method: In March 2015, an online survey was widely disseminated in the suicidology community. Results: The questionnaire was accessed 77 times, and 22 records were included in the analysis. The respondents provided valuable information regarding current research projects and recommendations for the future. Limitations: Bearing in mind the modest number of replies, all from respondents in Westernized countries, it is not known how representative the findings are. Conclusion: The survey generated three strategies for future postvention research: increase intercultural collaboration, increase theory-driven research, and build bonds between research and practice. Future surveys should include experiences with obtaining research grants and ethical approval for postvention studies.
