ABSTRACT

Three new records of Chirostylidae and Munididae off Thoothukudi coast of Gulfof Mannar, southeast coast of India and reported. Eumunida funambulus, Agononida eminensand Munida heteracantha, of which, the second and third species were newly recorded fromIndian waters. The first species (Eumunida funambulus) is recorded from Thoothukudicoast of Gulf of Mannar, southeast coast of India. Three specimens were reported in depth of300 mts as an incidental by-catch in the fisheries. They are found in tropical waters fromabout 08º 53.6'N 78º 16'E and 08º 53.8'N 78º 32'E/300m/35 miles from Thoothukudi fishingharbour, southeast coast of India.

Keywords: Crustacea, Decapoda, Anomura, Chirostylidae and Munididae, Eumunida funambulus,Agononida eminens and Munida heteracantha new records.

Taxonomical studies on the Chirostylidand Galatheid lobsters of India are dealt with byWood-Mason in Wood-Mason & Alcock (1891),Alcock (1894 & 1901), Alcock & Anderson (1894,1895, 1896, 1899a, 1899b & 1901), Alcock & McArdle(1902), Anderson (1896), MacGilchrist (1905), Alcock& MacGilchrist (1905), Balss (1913a), Doflein &

Balss (1913), George and Rao (1966), Rao (1974) andTirmizi & Javed (1993). A total of 47 species (10from Family: Chirostylidae and 37 from FamilyGalatheidae) are recorded, mostly from the deeperwaters of Lakshadweep Sea, Arabian Sea, Bay ofBengal and Andaman Sea, while a single galatheidlobster Munidopsis regia Alcock & Anderson, 1894

has been reported from Gulf of Mannar. Whileexamining the crustacean catches landed by largertrawlers, which operated in deeper waters offThoothukudi, three species of squat lobsters werenoticed. On closer examination, they were identifiedas Eumunida funambulus, Agononida eminens andMunida heteracantha, of which, the second and thirdspecies were new to Indian waters. The first species(Eumunida funambulus) is recorded from Gulf ofMannar for the first time, though it has been reportedearlier from southwest coast of India by George andRao (1966). Thus, the total number of squat lobstersfrom India now rose to 49. The taxonomic andsystematic position of three species reported hereis followed the new classification given by Schnabel& Ahyong (2010) and Schnabel et al. (2011) for theSuperfamily Chirostyloidea and by Ahyong et al.(2010) for the Superfamily Galatheoidea.

Superfamily: Chirostylidea Ortmann, 1892

Material: 1 male measuring 14.6 cm total length and25g weight (Fig.1).

Locality: 08º 53.6'N 78º 16'E and 08º 53.8'N 78º 32'Eoff Thoothukudi coast of Gulf of Mannar, Southeastcoast of India; depth at trawling 300 m.

Remarks: The description given by Gordon (1930)and Baba (1988) agree with the present specimen.Carapace rounded with transverse ridges and armed

with 7 spines each on its anterolateral margins;rostrum short and more than one-third of thecarapace length; 3 hepatic spines runningbackwards and outwards from base of outersupraorbital spine; a very small spine presentoutside of these three spines on the left side, asobserved by (Gordon, 1930); thoracic sternitebearing third maxilliped with pair of spines and a V-shaped notch between the pair (Fig. 1B); sternitebearing chelipeds also with a stout lateral marginalspine on each side.

Colour: Carapace dark brown and abdomen lightyellowish brown; rostrum, supraorbital spines andthose spines on anterolateral border of carapaceand legs with white tips.

Distribution: This species has been recorded earlierfrom off Alappuzha, southwest coast of India at338 m (George and Rao, 1966). The present recordfrom Thoothukudi coast in Gulf of Mannar extendsits distribution to the southeast coast of India.Other records from Indo-Pacific region are from Gulfof Aden, Socotra Channel between Aden andMumbai, Madura Strait, Java, Kwandang Bay, NorthCelebes, off North Mindanao, between Cebu andBohol, South China Sea off Southwest Luzon, SahulBank, south of Timor, East coast of Kyushu, Japan(Baba et al., 2008).

Colour: Carapace light orange with orange-redspines; chelipeds with orange bands acrossarticulations and orange-red spines; walking legswith orange meri and propodi; dactyli red distally;spines orange-red.

Distribution: The occurrence of this species iswidely distributed in the Indo-Pacific region fromthe Philippines between Mindanao and Luzon, theEast China Sea, the Bonin Islands, and Sagami Bayand vicinity. The present record from Thoothukudicoast of Gulf of Mannar is the first one from IndianOcean.
