Neripteron cornucopia is a species of freshwater snail, an aquatic gastropod mollusk in the family Neritidae, the nerites.[4]

Distribution

Distribution of Neripteron cornucopia include Odisha state and West Bengal in India, Myanmar, Vietnam,[5] Mai Po Marshes Nature reserve in Hong Kong,[6] Singapore[7][8] Jambi province in Indonesia,[9] and Japan.[6] Records from Japan were incorrectly identified as Neripteron violaceum prior to 1997.[6]

The type locality is "Hugli estuary at Fort William and Tolly’s Nullah", now in Kolkata.[8] William Thomas Blanford also reported this species from Irrawaddy River delta from Bago, Myanmar in 1867.[10][8] It was rediscovered from India after 180 years in 2017.[8]

Description

Neripteron cornucopia was originally described under the name Neritina cornucopia by William Henry Benson in 1836. Benson' original text (the type description) in Latin and English reads as follows:[1]

The color of the live snail is black or dark grayish with black outline.[8]

The color of the shell is dark brown.[8] The coloration has also purplish and greenish spiral bands.[8] Algae or silt are on periostracum usually.[8]

The width of the shell is 10–13 mm in India,[8] 7.2-12.9 mm in Hong Kong,[6] and 6–17 mm in Singapore.[7] The height of the shell is 4.5-9.2 mm in Hong Kong.[6] The length of the shell is 13-19.6 mm in India,[8] up to 17.4 mm in Hong Kong,[6] and 9–24 mm in Singapore.[7]

The operculum has paucispiral nucleus with a small initial region.[11]

The Radula was described and depicted by Huang in 1997.[6]

There is X0 sex-determination system in Neripteron cornucopia: the diploid number of chromosomes (2n) is 27 in males and 28 in females (2n = 26 + XX (or XO)).[6]

Neripteron violaceum (synonym: Neritina depressa) is similar species. Neripteron auriculatum is very similar to juveniles of Neripteron cornucopia.[7]

Ecology

Neripteron cornucopia lives in intertidal mangroves.[8] For example, Blanford collected them on stems of nipa palm Nypa fruticans.[10] It lives in water on various substrates: on mud, on fallen leaves, on stones and under stones, on concrete.[7]
