INTRODUCTION

Brachyuran crab species of the family Camptandriidae Stimpson, 1858 are commonly found in the estuarine, mangrove mudflat and open mudflat habitats in the Indo-West Pacific regions (Jones and Clayton, 1983Jones, D. and Clayton, D. 1983. The systematics and ecology of crabs belonging to the genera Cleistostoma De Haan and Paracleistostoma De Man on Kuwait mudflats. Crustaceana, 45: 183-199.). Camptandriidae is represented by around 40 species belonging to 22 genera worldwide (Ng et al., 2008Ng, P.K.; Guinot, D. and Davie, P.J. 2008. Systema Brachyurorum: Part I.

Specimens were collected from the mangrove mudflat habitat of Jakhau village, located in Gulf of Kachchh region of Gujarat state, India. Specimens were washed properly to remove debris and photographed. They were preserved in 10 % formalin and deposited in the Zoological Reference collection (LFSc.ZRC), Department of Life Sciences, Hemchandracharya North Gujarat University, Patan, Gujarat, India.

Remarks. The specimens examined in the present study show close agreement with the original description given by Jones and Clayton (1983Jones, D. and Clayton, D. 1983.

Journal of Crustacean Biology, 16: 797-813.) established a new genus, Manningis for P. arabicum. The male and female of M. arabicum look similar in their overall morphology but show sexual dimorphism in relative cheliped size where males bear well developed and robust chelipeds and females bear slender chelipeds with a spatulate tip.

Manningis closely resembles Nasima, but can be distinguished from the latter on the basis of the following characters: robust chelipeds in the male, having a quadrangular palm, while the female has a slender cheliped with the palm longer than broad (versus chelipeds similar in the male and female of Nasima, Al-Khayat and Jones, 1996Al-Khayat, J.A. and Jones, D.A. 1996.

The first record of Manningis arabicum (Jones & Clayton, 1983) (Decapoda: Camptandriidae) from intertidal mud flats of Pakistan. Acta Zoologica Bulgarica, 69: 489-492.), and now it is also known from mangrove habitat of Jakhau port of Gujarat state, located on the northwestern coast of India. The species is found in the lower intertidal zone of mangrove habitat at Jakhau port where it shares habitat with Nasima dotilliformis (Alcock, 1900). Manningis arabicum is a deposit feeder and is found in small burrows present along the bank of creeks passing through the mangroves.
