These four new species belong to the subgenus Biwamelania. Semisulcospira (Biwamelania) reticulataformis, sp. nov., Semisulcospira (Biwamelania) nojirina, sp. nov., Semisulcospira (Biwamelania) gamoensis, sp. nov., and Semisulcospira (Biwamelania) tagaensis, sp. nov. are newly described herein. The authorship of Biwamelania is attributed to Matsuoka and Nakamura (1981) and Melania niponica Smith, 1876, is designated as the type species of Biwamelania by Matsuoka and Nakamura (1981).

  • Species Fact Sheet with Juga Hemphilli Hemphilli
    SPECIES FACT SHEET Scientific Name: Juga hemphilli hemphilli (Henderson 1935) Common Name: barren juga Phylum: Mollusca Class: Gastropoda Order: Neotaenioglossa Family: Semisulcospiridae Taxonomic Note: Past genetic analysis by Lee et al. (2006) based on incorrectly identified museum voucher specimens suggested reassignment of the related subspecies Juga hemphilli dallesensis (and therefore the Juga hemphilli conspecifics, including Juga hemphilli hemphilli) to the genus Elimia. However, Foighil et al. (2009) conducted an additional analysis and determined that Juga hemphilli is indeed most closely related to other western Juga and should not be reassigned to the genus Elimia. Turgeon et al. (1998) do not recognize any subspecies of Juga hemphilli. Conservation Status: Global Status: G2T1 (May 2009) National Status: United States (N1) (June 2000) State Statuses: Oregon (S1), Wahington (S1) (NatureServe 2015) IUCN Red List: NE – Not evaluated Technical Description: This subspecies was originally described as Goniobasis hemphilli hemphilli (Henderson 1935). Burch (1982; 1989) revised this subspecies to the genus Juga to reflect the distribution of taxa west of the Continental Divide. Adult: Juga is a genus of medium-sized, aquatic, gilled snails traditionally treated as part of the subfamily Semisulcospirinae within the Pleuroceridae family, although the Semisulcospirinae subfamily was recently elevated to family level based on morphological and molecular evidence (Strong and Köhler 2009). The Pleuroceridae and Semisulcospiridae families both differ from the Hydrobiidae family in that the males lack a verge (male copulatory organ). The genus Juga is distinct from related pleurocerid snails based on reproductive anatomy and egg mass characters (Taylor 1966), as well as features of the ovipositor pore, radula, midgut, kidney, and pallial gonoduct (Strong and Frest 2007).

  • Seasonal Reproductive Anatomy and Sperm Storage in Pleurocerid Gastropods (Cerithioidea: Pleuroceridae) Nathan V
    989 ARTICLE Seasonal reproductive anatomy and sperm storage in pleurocerid gastropods (Cerithioidea: Pleuroceridae) Nathan V. Whelan and Ellen E. Strong Abstract: Life histories, including anatomy and behavior, are a critically understudied component of gastropod biology, especially for imperiled freshwater species of Pleuroceridae. This aspect of their biology provides important insights into understanding how evolution has shaped optimal reproductive success and is critical for informing management and conser- vation strategies. One particularly understudied facet is seasonal variation in reproductive form and function. For example, some have hypothesized that females store sperm over winter or longer, but no study has explored seasonal variation in accessory reproductive anatomy. We examined the gross anatomy and fine structure of female accessory reproductive structures (pallial oviduct, ovipositor) of four species in two genera (round rocksnail, Leptoxis ampla (Anthony, 1855); smooth hornsnail, Pleurocera prasinata (Conrad, 1834); skirted hornsnail, Pleurocera pyrenella (Conrad, 1834); silty hornsnail, Pleurocera canaliculata (Say, 1821)). Histological analyses show that despite lacking a seminal receptacle, females of these species are capable of storing orientated sperm in their spermatophore bursa. Additionally, we found that they undergo conspicuous seasonal atrophy of the pallial oviduct outside the reproductive season, and there is no evidence that they overwinter sperm. The reallocation of resources primarily to somatic functions outside of the egg-laying season is likely an adaptation that increases survival chances during winter months. Key words: Pleuroceridae, Leptoxis, Pleurocera, freshwater gastropods, reproduction, sperm storage, anatomy. Résumé : Les cycles biologiques, y compris de l’anatomie et du comportement, constituent un élément gravement sous-étudié de la biologie des gastéropodes, particulièrement en ce qui concerne les espèces d’eau douce menacées de pleurocéridés.
