They were previously known only from their holotypes: male and female, respectively. They belong to a distinct group of small-sized sepiids, all nearendemics of southern African waters. The knowledge of the systematics and biology of this group is still limited despite the long time since the first description (1875). This is because, inter alia, of their small size: not larger than 4 cm mantle length at maturity. Twenty-one individuals of S. robsoni described here were scattered from Port Nolloth area to the Tsitsikamma coast (bottom depth <37–449 m). Eight known individuals of S. faurei came from the eastern Agulhas Bank (bottom depth 116–184 m). S. robsoni can be identified by extremely thinly calcified cuttlebone (transparent); smooth skin of dorsal mantle and head; tips of first pair of arms thick, finger-like, devoid of suckers. S. faurei can be distinguished by the following combination of characters: thick, heavily calcified cuttlebone but with flat and fused inner cone; skin of dorsal mantle and head very densely covered by characteristic warts; thin, whip-like tips of first pair of arms devoid of suckers. All described specimens of both species are deposited in the South African Institute of Aquatic Biodiversity (SAIAB) and in Iziko, South African Museum (SAMC). key words: small cuttlefish; redescriptions; South African waters; Sepia; Digitosepia","PeriodicalId":309868,"journal":{"name":"Folia Malacologica","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127911999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Poland) were subject to malacological analysis in order to reconstruct the history of environmental transformations of the pond from its establishment in 1351 to the end of its functioning in 1960. Thirty five mollusc taxa occurred in the pond during its functioning: 21 taxa of water snails, 11 bivalves, and 3 terrestrial snails. Six phases of development of the pond were distinguished, based on the mollusc assemblages: phase I (1351–1450 CE) – very favourable habitat conditions, high species richness and diversity; phase II (1450– 1490 CE) – deterioration of habitat conditions – decrease in the number of species and individuals; phase III (1490–1590 CE) – improving conditions and reappearance of species which had occurred in the pond in phase I; phase IV (1590–1750 CE) – the least favourable conditions and poor malacofauna in terms of species number and abundance; phase V (1750–1790 CE) – renewed development of the malacofauna; phase VI (after 1790 CE) – end of functioning of the pond. The phases of pond development were associated with hydrological transformations, resulting from climatic factors and human economic activity. key Words: mollusc assemblages; millpond deposits; last millennium; Jarosławianka Stream; Pomerania; Poland","PeriodicalId":309868,"journal":{"name":"Folia Malacologica","volume":"205 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122369045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is the intermediate host of Pleurogonius malaclemys whose definitive host is the diamondback terrapin (Malaclemys terrapin terrapin). P. malaclemys forms dome-like cysts on the snail’s operculum. The study was aimed at observing differences in the snail’s physical parameters (shell height, thickness, and snail weight) under the effect of the environmental quality and the prevalence of P. malaclemys. Snails were collected, along with samples of water and bottom deposits, from two locations in Barnegat Bay, New Jersey. In the area with poorer quality of sediment and water, the prevalence of parasite’s cysts was significantly higher, and the shells were thinner and lower. Histological analyses revealed the presence of metacercariae and tissue anomalies. Increasing prevalence of the parasite was correlated with deteriorating ecosystem health, leading to a combined detrimental effect on the host. This study is a model of the repercussions of deteriorating habitat quality on host-parasite relationships, and the health of the organisms in question.

Its present distribution is limited to the eastern Agulhas Bank (depth range 119–184 m), but this was based on a small material. It is recognised by prominently dorsal eyes and four turrets (papillae on top of each other) dorsally on the head between the eyes. On the dorsal mantle: four large, prominent patches, two mid anteriorly and two mid posteriorly; smaller turrets, patches and/or tubercles and warts dorsally; skin between these structures smooth and shiny. Ends of I pair of arms without suckers. Cuttlebone lightly calcified, thin and fragile. Second new species, Sepia roeleveldi sp. nov. is also described (distribution: from Hondeklip to Port Alfred, depth range 181–497 m), and is recognised by small, flat warts very densely and uniformly covering dorsal mantle, head and arms. Two prominent tubercles covered by warts on dorsal head; one similar tubercle in the middle of dorsal mantle (sometimes missing). Ends of I pair of arms without suckers. Cuttlebone thin and fragile, thinly calcified. Description of these new small cuttlefish has led to proposing a new subgenus Digitosepia with four species.
