Strianassa lerayi gen. et sp. nov., a new laomediid mud-shrimp from the eastern Pacific, with new records of Axianassa ngochoae Anker, 2010 and Heteroaxianassa heardi (Anker, 2011) in the western Pacific (Malacostraca: Decapoda: Gebiidea) Author Anker, Arthur text Zootaxa 2020 2020-07-29 4820 3 523 539 journal article 9177 10.11646/zootaxa.4820.3.6 566f9922-d257-41d4-acdc-2afbdcf1b495 1175-5326 4398178 21DA765A-133B-4419-B108-2E5E6AE0667D Axianassa ngochoae Anker, 2010 ( Fig. 8 ) Axianassa ngochoae Anker 2010: 50 , figs. 1–8; Ngoc-Ho 2014: 556 , fig. 5. Material examined . 1 female (cl 6.2 mm , missing left cheliped), MNHN-IU-2018-986, New Caledonia , Pouébo , near Pouébo estuary, 20°22’43.0”S– 164°35’01.4”E , near-shore sand-mud flat near estuary of small river, deep nearshore pool with muddy bottom, depth at low tide: 0.3–0.5 m , suction pump, in burrow, leg. A. Anker , 18 September 2018 . Remarks . The present specimen ( Fig. 8 ) represents the first record of A. ngochoae from New Caledonia . The species was previously known from the type series from Moorea Island, Society Islands, French Polynesia ( Anker 2010 ), as well as a single young male specimen from southern Vietnam ( Ngoc-Ho 2014 ). Axianassa ngochoae can be easily distinguished from the other two western Pacific congeners, for instance, from A. planioculus Komai & Fujita, 2019 by the dagger-shaped (not distally bifid) antennal scale, and from A. sinica Liu & Liu, 2010 by the rounded (not pointed) rostrum and the cheliped meri unarmed on their ventromesial margins ( vs. with a strong subdistal tooth in A. sinica ).
