Two pasiphaeid shrimps, Leptochela (Leptochela) irrobusta Chace, 1976 and Leptochela (Leptochela) chacei Hayashi, 1995, were collected in samples from the South China Sea, marking the first time these species have been found in Chinese waters and thus as Chinese fauna. These two pasiphaeid species belong to the genus Leptochela Stimpson, 1860. L. (L.) chacei was previously known to be distributed in tropical regions: Viet-Nam, New Caledonia and Madagascar. This paper represents its first record from a temperate zone, which is unusual for its habitation. These two species are redescribed in detail and their current zoogeographical distributions are discussed. In addition to these two species, five species of Leptochela have previously been recorded from China. We used these species to provide a key to the Leptochela species from China.

Based on samples collected from the Yellow Sea in October 2014, a new species of pasiphaeid shrimp, Leptochela (Leptochela) tuerkayi sp. nov., is described. The new species is closely related to L. (L.) gracilis Stimpson, 1860 in morphology but differs from the latter and other congeners by the following combination of characters: three longitudinal dorsal carinae in ovigerous females, third maxilliped with the rather short exopod slightly overreaching the distal margin of the antepenultimate segment and the fourth pereiopod with the exopod reaching beyond the end of the merus. Morphological data and a partial sequence of the 16S rRNA gene of the new species are provided to show its systematic position.
