First Record of Paranebalia longipes (Crustacea: Phyllocarida: Leptostraca) from South Korea

Abstract

Paranebalia longipes (Willemoes-Suhm, 1875) is cosmopolitan and has been usually found in the algal and sponge debris on the sandy mud substrates. This species can be clearly distinguished from other species of Paranebalia by the presence of serration on posterior margin of pleopods, the number of articles on antennule and antenna, and number of teeth on flange of antennule fourth article. The genus Paranebalia is new to Korea. In this paper, we provide detail descriptions of the diagnostic characteristics and illustrations of the P. longipes. Additionally, type locality and world distribution of the genus Paranebalia are provided.

First record of the genus Paranebalia Claus, 1880 (Crustacea: Leptostraca) from the Mediterranean Sea

“…Ledoyer (2000) described the subspecies P. longipes neocaledoniensis Ledoyer, 2000 from New Caledonia that mainly differs from the nominal species in the shape and number of eye denticulations and the number of comb-row 'spines' of the pleopod I exopod. Thus, P. longipes has been regarded as a cosmopolitan species (Song et al, 2012); this view was also held for species of Nebalia Leach, 1814 for long (Claus, 1888;Thiele, 1904) but in the last decades it has been proven wrong. Indeed, many new species of Nebalia have been described in the last 20 years and several species may coexist in the same geographic area even at small spatial scales (i.e.…”

“…The genus Paranebalia is distributed along the Western Atlantic, east Asia, Indian and Pacific oceans (Song et al, 2012); Menorca (Balearic Islands, western Mediterranean; this work). Mediterranean specimens have been found in muddy sediments at 28 m depth with a high abundance of the serpulid polychaete Ditrupa arietina (Müller, 1776); other species collected were the bivalves Nucula sulcata Bronn, 1831, Myrtea spinifera (Montagu, 1803) and Corbula gibba (Olivi, 1792), the decapods Ilia nucleus (Linnaeus, 1758) and Pagurus prideaux Leach, 1815, and the echinoderms Spatangus purpureus Müller, 1776 and Astropecten aranciacus (Linnaeus, 1758).…”

“…On the contrary, Paranebalia is a pantropical genus (Haney & Martin, 2016) and has mostly been reported from temperate and tropical latitudes, usually in intertidal and shallow depths (< 100 m) associated with algae, seagrasses, sponges, corals, and sedimentary environments (e.g. Gamô & Takizawa, 1986;Modlin, 1996;Ledoyer, 2000;Song et al, 2012). Furthermore, undescribed species of Paranebalia from Australia still await formal description (Walker-Smith, 2000;Walker-Smith & Poore, 2001).…”

“…); other records include Japan (Thiele, 1904;Gamô & Takizawa, 1986), South Korea (Song et al, 2012), and across the Indian and Pacific oceans (Thiele, 1904;Ledoyer, 1994Ledoyer, , 2001. Ledoyer (2000) described the subspecies P. longipes neocaledoniensis Ledoyer, 2000 from New Caledonia that mainly differs from the nominal species in the shape and number of eye denticulations and the number of comb-row 'spines' of the pleopod I exopod.…”

“…Dahl, 1985;Haney & Martin, 2005;Lee & Morton, 2005;Moreira et al, 2009). Leptostraca comprises three extant families (Walker-Smith & Poore, 2001) of which Paranebaliidae Walker-Smith & Poore, 2001 is composed by three genera and a total of six species (Song et al, 2012): Paranebalia Claus, 1880 (three species and one subspecies), Levinebalia Walker-Smith, 2000 (two species), and Saronebalia Haney & Martin, 2004 (one species). To date, Levinebalia has only been found in New Zealand and Australia (Wakabara, 1976;Walker-Smith, 2000) and Saronebalia in the Caribbean Sea (Haney & Martin, 2004).…”
