Pachelpheus pachyacanthus sp. nov. appears to be an obligate symbiont dwelling in burrows of yet unknown infaunal hosts, on shallow near-shore subtidal sand flats. The main morphological characters of Pachelpheus gen. nov. are: (1) frontal margin of carapace with broadly rounded rostral projection, without orbital teeth; (2) sixth pleonite with articulated plate; (3) telson with two pairs of cuspidate setae dorsally, without anal tubercles; (4) eyes concealed in dorsal view, partly visible in lateral view; (5) chelipeds equal in size, symmetrical in shape, moderately enlarged, stout, carried extended; (6) cheliped carpus without rows of setae mesially; (7) cheliped fingers without snapping mechanism, each finger armed with one stout tooth; (8) second pereiopod carpus with five sub-articles; (9) third, fourth and fifth pereiopods with ischia armed with single robust cuspidate seta, meri armed with one to several unusually robust cuspidate setae; (10) second pleopod with appendix masculina in males only; (11) uropodal exopod and endopod with rows of slender spiniform setae on their distal margins; (12) uropodal diaeresis unusually thickened laterally, with two very stout spiniform setae; and (13) lateral lobe of the uropodal protopod rounded.
