Remarks . Vaunthompsonia budaii sp. nov. is closely related to V. floridana Băcescu (1971) from Florida and Jamaica ( Petrescu, Iliffe & Sarbu, 1993 ) with pleonite 6 without denticulate apical margin. The V. budaii sp. nov. differs in the absence of characteristic pigmented spots on dorsal side of carapace, pereon and pleon and from the propodus of pereopod 1, all present in V. floridana . The anterior part of carapace (in lateral view) is broader and frontal apex blunt in V. floridana (See Fig. 8A Petrescu et al. 1993 ) while in V. budaii the anterior part of the carapace (in lateral view) is narrower than V. floridana and frontal apex pointed ( Fig. 6 A). The other differences between V. budaii sp. nov. and V. floridana are: 1) carapace longer (ratio length/height, 1.75 vs. 1.68), 2) pereopod 1, merus/ischium, 2.00 vs. 1.66, carpus/merus, 1.86 vs. 2.50, carpus/propodus, 1.17 vs. 1.2, propodus/dactylus, 0.75 vs. 0.65, 3) pereopod 2, basis with 7 vs. 6 setae on medial margin, carpus with 2 setae on outer margin vs. 1, dactylus with 3 setae on each margin vs. 2, 4 subterminal setae vs. 2, 4) pereopod 3 ischium without setae vs. 1, merus with 2 setae vs. none, propodus without setae vs. 1 seta, 5) pereopod 4 basis without setae vs. 2, ischium without setae vs. 2, merus with 1 seta vs. 2, carpus with 3 setae vs. 5, 6) pereopod 5 basis with 3 setae vs. 8, ischium with 1 seta vs. 2, merus with 1 seta vs. 3, carpus with 3 simple setae vs. 7, 7) uropodal peduncle with 8 vs. 12 setae, distal article of exopod with 5 setae vs. 7, distal article of endopod with 4 vs. 3 setae on medial margin.
