Rediscovery and range extension of Ciliopagurus liui Forest, 1995 and description of a new species of Pagurus Fabricius, 1775 (Crustacea: Decapoda: Anomura: Paguroidea) from the Kerala State, southwestern India

Abstract

Two species of paguroid hermit crabs, Ciliopagurus liui Forest, 1995 (Diogenidae) and Pagurus spinossior n. sp. (Paguridae), are reported from the Kerala State, southwestern India. Ciliopagurus liui, is first recorded from the Indian Ocean. This species was originally described on the basis of a single male specimen from the Tonkin Gulf in the South China Sea, though its geographical range also included Japan, based on literature. Supplemental description and illustrations are provided for better understanding of the diagnostic features of this little known species. Pagurus spinossior n. sp., described on the basis of a single male specimen, appears closest to P. spinulentus (Henderson, 1888), known only by the holotype from the Philippines, but the lack of spinules on the dorsal margins of the dactyli of the second pereopods, the different shape of the anterior lobe of the thoracic sternite 6, and the more numerous spines on the terminal to posterior margins of the telson distinguish the new species from P. spinulentus.

Filling the early Eocene gap of paguroids (Decapoda, Anomura): a new highly diversified fauna from the Spanish Pyrenees (Serraduy Formation, Graus-Tremp Basin)

“…Fossil species are also characterized by globular, convex surfaces with the outer surface of the propodus densely granulated (Via, 1959; Schweitzer and Feldmann, 2001; De Angeli and Caporiondo, 2017). Some recent species (i.e., P. spinossior Komai, Reshmi, and Kumar, 2013) bear similarities with the scarce material recovered, so we tentatively assign the new material to this genus.…”

A new distribution record of stomatopods Odontodactylus japonicus (De Haan, 1844) and Lysiosquilla tredecimdentata (Holthuis, 1941) from the Puducherry coastal waters, east coast of India

“…Although stomatopods occur along the entire Indian coast, most published records are from localities on the eastern coast. Recent studies of commercial trawl by-catch primarily along the southern and southwestern coasts (Tamil Nadu and Kerala) resulted in numerous new records and discoveries of decapod crustaceans (Komai et al 2013;Kumar et al 2013;Ng et al 2016Ng et al , 2017Yang et al 2017). The pan tropical stomatopod genus Lysiosquilla, which includes the largest known stomatopods, comprises 12 species, five of which are reported in the Indo-West Pacific region.…”

First record of two species of hermit crabs (Decapoda, Paguridae) from South Korea, with remarks on the associated hydrozoan, Hydrissa sodalis

“…The genus Pagurus Fabricius, 1775 has been considered as the polyphyletic group in the family Paguridea Latreille, 1802(McLaughlin et al, 2007Mantelatto et al, 2009;Olguin & Mantelatto, 2013) and consists of 177 species worldwide (McLaughlin et al, 2010;Ayón-Parente & Hendrickx, 2012;Komai et al, 2013Komai et al, , 2015Komai & Rahayu, 2014;Muñoz et al, 2014;Lima & Lemaitre, 2016). In Korea, the following 28 species of Pagurus have been reported: P. angustus (Stimpson, 1858), P. brachiomastus (Thallwitz, 1892), P. conformis De Haan, 1849, P. constans (Stimpson, 1858), P. decimbranchiae Komai & Osawa, 2001, P. exiguus (Melin, 1939, P. filholi (de Man, 1887), P. gracilipes (Stimpson, 1858), P. imaii (Yokoya, 1939), P. japonicus (Stimpson, 1858), P. lanuginosus De Haan, 1849, P. maculosus Komai & Imafuku, 1996, P. middendorffi Brandt, 1851, P. minutus Hess, 1865, P. nigrivittatus Komai, 2003, P. nigrofascia Komai, 1996, P. nipponensis (Yokoya, 1933, P. ochotensis Brandt, 1851, P. parvispina Komai, 1997, P. pectinatus (Stimpson, 1858), P. proximus Komai, 2000, P. rathbuni (Benedict, 1892, P. rubrior Komai, 2003, P. similis (Ortmann, 1892, P. simulans Komai, 2000, P. spina Komai, 1994 trigonocheirus (Stimpson, 1858), and P. undosus (Benedict, 1892) (Kamita, 1954(Kamita, , 1955Kim, 1963…”
