Genus Grallenia

Species of the genus Grallenia are unique among gobiids in possessing a combination of 15 segmented caudal-fin rays, a greatly reduced papilla row e, and a pair of characteristic diagonal black markings at the base of the caudal fin (Shibukawa & Iwata 2007). The most useful features for separating the various species include the number of dorsal- and anal-fin rays, patterns of body scalation, dorsal-fin shape, and the presence or absence of cephalic sensory-canal pores and a filamentous extension of the first dorsal-fin spine (Allen & Erdmann 2017).
