“…The presence of minutely pectinate cutting edges of spatulate to subspatulate first chelipeds is considered to be a definitive character for the studied ingroup genera (e.g., Bruce, 1995;Fransen & Van der Meij, 2010), but was also found in the related outgroup species Lipkemenes, Zenopontonia, Actinimenes and both Periclimenes colemani and P. kempi (supplementary appendix S1, supplementary table S2). A quick investigation also proves that Sandimenes and various members of Periclimenes and Allopontonia (which were proven to be somewhat related to the currently studied ingroup by Chow et al, 2021) also have subspatulate first chelipeds, although the associated minutely pectinate cutting edges cannot be seen in the published illustrations (Bruce, 1971(Bruce, , 1972b(Bruce, , 1995(Bruce, , 2010bLi, 2009;Rauch et al, 2019), except for the illustrations of P. josephi, which show "a distal row of pectinate short setae" (Li, 2008b). Closer examination of collection material is needed in order to see if minutely pectinate cutting edges are also present in related ectosymbiotic species.…”
