1B4C87A2FF88FFEF3EC556F0FBE3F8E5.taxon	etymology	Etymology. Combination of the Greek word karis meaning of shrimp, and the name of our friend, the late Dr. Ngan Kee Ng (1966 – 2022), who made numerous contributions on decapod crustacean taxonomy and gave us her warmest hospitality during our stay in Singapore. Gender: feminine. Species included. In addition to the type species, Ngankeecaris acanthimera (Bruce, 2006) comb. nov., known only from the holotype captured at New Caledonia, belongs to the present new genus. Common name. Gouzanze-kakure-ebi zoku (new standard Japanese name).	en	Okuno, Junji, Yoshida, Ryuta (2024): A new genus, Ngankeecaris (Decapoda, Palaemonidae), with supplementary records of its type species, N. dardanicola (Bruce & Okuno, 2006) from the Ryukyu Islands, Japan. Zootaxa 5476 (1): 342-346, DOI: 10.11646/zootaxa.5476.1.27, URL: http://dx.doi.org/10.11646/zootaxa.5476.1.27
1B4C87A2FF88FFEF3EC556F0FBE3F8E5.taxon	discussion	Remarks. As in the case of Periclimenes granuloides Hayashi, 1986, P. tonga Bruce, 1988, and Rapimenes granulimanus (Bruce, 1978), some species included in Periclimenes sensu stricto and its closely related genera have the second pereiopod covered with granulations (Li 2000). However, the presence of the short transvers rows of spinulate tubercles on the ventral surface of the second pereiopod (Fig. 1 C) is an unusual morphological feature that only two species, N. dardanicola and N. acanthimera possess. Bruce (2006: fig. 6) represented the details of this feature by SEM images. The structure of the thoracic sternites has not been previously described in N. dardanicola comb. nov. (see Bruce & Okuno 2006). In the holotype and paratype from Suruga Bay and an additional specimen from the Ryukyu Island, we can observe the presence of anterior transverse ridge with median notch on the fourth and fifth sternites. The ridges of the fifth sternite are higher than those of the fourth, and the notch is more distinct in the fifth than in the fourth (Fig. 1 B). These morphological features in N. dardanicola comb. nov. are similar as those reported for N. acanthimera comb. nov. by Bruce (2006). The general body form of Ngankeecaris gen. nov. resembles some of the Periclimenes members, P. paraparvus Bruce, 1969, P. parvispinatus Bruce, 1990, and P. parvus Borradaile, 1898. These three species have been known only by their type specimens. Ngankeecaris gen. nov. shares with them the following morphological features: 1) the rostrum directed downwards, with deep lamina dorsally and ventrally dentate (Fig. 1 A); 2) the supraorbital spine and eave being absent (Fig. 1 A); 3) the dactylus of the first pereiopod not being subspatulate; and 4) the ambulatory pereiopods having biunguiculate dactyli. However, the feebly developed pterygostomial margin of the carapace (Fig. 1 A) distinguishes Ngankeecaris gen. nov. from these Periclimenes species having a markedly produced subrectangular pterygostomial margin in addition to the row of tubercles on the ventral surface of the second pereiopods in Ngankeecaris gen. nov. that are absent in these Periclimenes species (Bruce 1969, 1990; Bruce & Okuno 2006). Bruce (1969) indicated that P. paraparvus is distinguished from P. parvus by the lack of the short transverse rows of tubercles on the palm of the second pereiopod. Periclimenes parvus compared here is regarded to refer to the specimen from Indonesia reported by Holthuis (1952), and subsequently this specimen was designated as one of the paratypes of N. dardanicola by Bruce & Okuno (2006). The re-examination of the syntype of P. parvus showed that its second pereiopod is unarmed (Bruce & Okuno 2006).	en	Okuno, Junji, Yoshida, Ryuta (2024): A new genus, Ngankeecaris (Decapoda, Palaemonidae), with supplementary records of its type species, N. dardanicola (Bruce & Okuno, 2006) from the Ryukyu Islands, Japan.

1B4C87A2FF8BFFEC3EC556F0FE4BFC9C.taxon	discussion	Remarks. Ngankeecaris dardanicola comb. nov. represents the unique dwelling in association with sea anemones attached on gastropod shells occupied by hermit crabs of the genus Dardanus Paul'son, 1875 (Bruce & Okuno 2006). The specimen from Okinawa (Fig. 2) was picked up on board the Teruyuki-maru, a commercial gillnet fishing vessel. Therefore, the host animals of the present specimen could not be determined. Ngankeecaris dardanicola comb. nov. is readily distinguished from it congener, N. acanthimera comb. nov., by the following key.	en	Okuno, Junji, Yoshida, Ryuta (2024): A new genus, Ngankeecaris (Decapoda, Palaemonidae), with supplementary records of its type species, N. dardanicola (Bruce & Okuno, 2006) from the Ryukyu Islands, Japan.
