Ashelby, Christopher W., Lin, Wei-Cheng, Grave, Sammy De & Chan, Tin-Yam, 2018, Notes on the shrimp genus Palaemon Weber, 1795 (Crustacea, Decapoda, Palaemonidae) and related genera from Taiwan, Zootaxa 4446 (4), pp. 575-595 : 579

Leandrites deschampsi ( Nobili, 1903)

( Fig. 3 )

Material examined. Kaohsiung Port, Kaohsiung City, 1 male (pocl 4.9 mm), 3 ovig. females (pocl 5.6–6.0 mm), 15.IV.1996 ( NTOU M01206 ) .

Diagnosis. Rostrum upturned distally, distinctly overreaching antennal scale; rostral formula 1–2+8–12/4–6; second pereopods overreaching antennal scale by length of chela and part of carpus; carpus distinctly longer than chela.

Colour pattern. Not recorded for the Taiwanese material.

Remarks. The present material agrees well with the description provided by Holthuis (1952a) and the figures in Li et al. (2007). In his supplementary description of Leandrites stenopus Holthuis, 1950 , Bruce (2000) noted the presence of a small pre-terminal tooth on each of the fingers of the chela of the first pereiopod, suggesting these could have been easily overlooked in other species of the genus; however, no such teeth were noted in the present material of L. deschampsi .

Ecology. High salinity brackish waters.

Distribution. Singapore, mainland China and now Taiwan.
