Salles et al. just published a paper on the tropical Helicarionid snail Ovachlamys fulgens (Gude, 1900) for which they used Brazilian material to redescribe the species.
Their abstract reads “The geographical distribution of the jumping snail Ovachlamys fulgens Gude, 1900, originally described from Loo-Choo Island, is expanding rapidly throughout the tropics. The full extent of the environmental damage caused by the in- troduction of this exotic species is still unknown. So far, it has been implicated in damage to orchids and horticultural plants. Ovachlamys fulgens is only known by a few characteristics of the shell and information on its anatomy is scant. The present study aims to redescribe this species based on specimens from Brazil, which is here characterized by the a globose shell, with wide aperture, externally micro-sculptured with undulating spiral groves, umbilicus partially obliterated by a thin plate, pedal sole tripartite, cephalopedal mass consisting of a series of oblique muscles, mantle with two flattened lobes, large caudal horn, pallial cavity small, vascular system evident, auricle fibrous, ventricle highly muscular, aorta subdivided in cephalic and gastric veins, a large kidney internally folded, jaw smooth and crescentic, radulae with 127 teeth per row (55-(8)- 1-(8)-55), each row with about 25 mm, crop absent, salivary glands fused, stomach large with thin walls, ovotestis with at least three distinct lobes, talon totally immersed in the albumen gland, uterus with two regions, capsule gland hardly visible, bursa copulatrix small and sacculiform, penial sheath present, epiphallus small and narrow, nervous ring asymmetrical, visceral ganglion on left side only, five and six nerves running from each cerebral and pedal ganglia, respectively, one statocyst immersed in each pedal ganglion, and two pairs of ganglia (mandibular and buccopharyngeal ganglia) extra to the nervous ring.”
The authors have done a thorough morphological and anatomical study, which will undoubtedly help to identify this species in future.
