Abstract: Machfudz Djajasasmita was an Indonesian malacologist who actively conducted research on Indonesian mollusks in the 20th century. He was the first Indonesian mollusk curator at the Museum Zoologicum Bogoriense, Indonesian Institute of Sciences, replacing Louis Johan Marie (LJM) Butot. During his life, he described three species and two subspecies of mollusks: Corbicula lacunae, Pterocyclos spiroliratus, Amphidromus minutus, Amphidromus poecilochrous asmani, and Amphidromus poecilochrous candidus. Additionally, one gastropod species was described after him, i.e. Amphidromus djajasasmitai Dharma, 1993. All the holotypes of these species are deposited at the Museum Zoologicum Bogoriense. Djajasasmita contributed 765 specimen lots at the museum and produced at least 27 important publications during his active career. For his significant contributions and dedication in Malacology, the Indonesian Malacological Society awarded him ‘the Father of Indonesian Malacologists’.
摘要：Machfudz Djasammita是20世纪印尼软体动物学家，积极从事软体动物研究。他是印度尼西亚科学研究所波哥大动物博物馆的首位印度尼西亚软体动物策展人，接替了Louis Johan Marie（LJM）Butot。在他的一生中，他描述了软体动物的三个物种和两个亚种：腔隙珊瑚、螺旋翼旋蝶、微小安菲罗摩、小安菲罗摩和白安菲罗莫。此外，有一种腹足纲物种以他的名字命名，即Amphitromus djajasasmitai Dharma，1993年。这些物种的所有正模标本都存放在波哥大动物博物馆。Djaasmita在其活跃的职业生涯中为博物馆贡献了765件标本，并出版了至少27本重要出版物。由于他在马六甲学方面的重大贡献和奉献精神，印尼马六甲学会授予他“印尼马六甲学家之父”。

: The Fernando de Noronha Archipelago off NE Brazil harbors a few unique terrestrial gastropod species. One of them, the mono-typic genus Ridleyconcha Christensen, 2020, presents such an idiosyncratic shell morphology that, in the 130 years since its description, it has been variously allocated in unrelated families: Streptaxidae, Endodontidae, Charopidae, Camaenidae, and Scolodontidae. Herein, R. quinque-lirata is included into a molecular phylogenetic framework of stylommatophoran land snails to clarify its taxonomic position. The analysis supports the latest morphological revision classifying Ridleyconcha in Scolodontidae. Considering the present sampling, Ridleyconcha appears to be the sister taxa of Entodina Ancey, 1887.

All previously known localities of Pyrgophorus parvulus (Guilding, 1828) on the Caribbean island of Montserrat were destroyed by volcanic eruptions starting in 1995. Here we document a population in a freshwater stream only indirectly affected by that eruption. Specimens collected on Montserrat are morphologically consistent with P. parvulus and 16S DNA sequences indicate genetic consistency.

Abstract: Invasive mollusks pose a serious threat to global freshwater diversity and have been implicated in many ecosystem-altering invasion events over the past few decades. Biomonitoring surveys are therefore a key tool for ensuring biosecurity in diversity hotspots and vulnerable habitats. In this study, we use DNA barcoding to provide the first record of the viviparid, Sinotaia cf. quadrata (Benson, 1842) from North America. Reciprocal monophyly and low genetic divergence (uncorrected p-distance: 0.004) with a Bellamya quadrata (Benson, 1842) individual from the type region (China) provides strong support for this identification. The species was recovered as part of a routine biomonitoring survey of the Adirondack region of northern New York. Only three adults were recovered (no populations or juveniles) suggesting that the discovery represents a very recent arrival. Considering the proximity of the sampling site from the massive St. Lawrence River, it is likely that S. cf. quadrata was introduced into the St. Lawrence, probably via the aquarium plant trade, and was able to spread into smaller river system in northern New York and possibly other border states. This record represents the fourth alien viviparid, the third of which is of Asian origin that have made its way to New York waters. Future biomonitoring efforts for the upcoming summer period will involve targeted searches for S. cf. quadrata to determine the extent of its spread in the region.

Abstract: Understanding the extent to which traits that are used to delimit and diagnose species are phenotypically plastic is important for recognizing species boundaries. Shell characters have long been used for describing species of gastropods, even though these features may be influenced by environmental conditions. To determine the degree of phenotypic plasticity of two North American lymnaeid species, Stagnicola elodes (Say, 1821) and Stagnicola emarginata (Say, 1821), that occur in different habitats and differ in shell morphology, we reared individuals in captivity under similar conditions and compared shell shapes and sizes of wild-caught and captive-reared populations. We also exposed individuals of S. elodes to effluent from a potential predator (crayfish) to gauge the possible impact of the presence of predators on shell morphology. Although the two species remained morphologically distinct, shell shapes of captive-reared individuals of both species differ significantly from those of wild-caught individuals and show similar magnitudes of change among species. Directions of change, however, differed significantly among species. Although shell shapes of individuals of S. elodes that were exposed to crayfish cues were not significantly different from control snails, shell sizes of exposed snails were smaller than unexposed snails. These results suggest that exposure to predators affects growth rates of S. elodes. Nonetheless, given significant associations between shell shape and size that were observed in the captive-rearing and predator-exposure experiments, shell shape changes allometrically during development. These results suggest that morphological differences of other North American Stagnicola species reflect ecophenotypic variation, but more work is necessary to further evaluate this hypothesis.

Abstract: Heteropods are predatory planktonic gastropods that are important in pelagic ecosystems. However, distributions of large heteropod species are poorly known. Heteropod collections from two midwater sampling programs conducted after the 2010 Deepwater Horizon oil spill (DWHOS): the Offshore Nekton Sampling and Analysis Program (ONSAP) in 2011 and the Deep Pelagic Nekton Dynamics of the Gulf of Mexico (DEEPEND) in 2015-2018 were used for this study These programs collected over 3,495 heteropods in the two target families from 46 sampling stations in the northern Gulf of Mexico (GOM). The zone along the northeastern GOM continental slope had the greatest species richness and abundances. The family Pterotracheidae (Pterotrachea coronata (Forsskal 1775), Pterotrachea hippocampus(Philippi 1836) and Pterotrachea scutata (Gegenbaur 1855) was the most abundant and contained the largest specimens examined. Common carinariids included Carinaria lamarcki (Péron & Lesuer 1810) and Cardiapoda placenta (Lesson 1830). We found evidence of diel migration in P. coronata and P. scutata but not for C. lamarcki, C. placenta or P. hippocampus. We evaluated body and eye size at capture depth for each species. There was no evidence of eye size increasing relative to body size with depth among the five species and relative eye size is species-specific. However, it was observed that vertical migrators had a different eye-type than the non-migrators. We determined that pterotracheids have smaller eyes relative to their total body size than carinariids. The allometric pattern of eye growth differed in P. scutata from those of the other species which could indicate that a factor other than depth plays a part in heteropod eye development. This is the first comprehensive study of large heteropods in the northern GOM which provides an important baseline for continued study of this pelagic gastropod.

In this study, we present mollusks of the family Caecidae Gray, 1850 collected between 2007 and 2008 from unconsolidated carbonate substrates of the Abrolhos coral bank during the PROABROLHOS Project (Productivity, Sustainability and Use of the Abrolhos Bank Ecosystem). A total of 649 individuals belonging to two genera and six species were collected from nine stations at depths of 15.6 to 22 m in the dry and rainy seasons. The most abundant species were Caecum brasilicum de Folin, 1874 and Caecum floridanum Stimpson, 1851. Caecum circumvolutum de Folin, 1867, Caecum metamorphosicum Lima, Santos & Absalao, 2013, Meioceras cubitatum de Folin, 1868 and Meioceras nitidum (Stimpson 1851) altogether comprised approximately 6.5% of the total number of individuals collected. Among the 14 species previously recorded for the Abrolhos coral reef area, Caecum metamorphosicum is for the first time registered in the area in this study. This calls attention that, overall, there is a need for more researches focused on the carbonate substrate in coral areas, especially on micro specimens.
