distribution
Distribution This is a relatively rare species, found in both tropical and temperate waters of the world’s Oceans. Prior to this study records from the Indian Ocean were only from tropical waters but the above three records are from off South Africa, two near Durban and one from as far south as 35 º 12 ’ S, 27 º 35 ’ E (Galathea stn. 176).

Type material Type material of V. pyripes could not be located at the SMNH, ZMUC or in Uppsala and is considered lost. However, the description and figures of Bovallius (1887 c) readily distinguish this species. No precise type locality is given by Bovallius (1887 a, c). He merely lists the distribution as “ Tropical parts of Atlantic ”. Type material of synonyms The syntypes of V. grandicornis (one male and one female) are in the MOM. The descriptions and figures of Chevreux (1900, 1935) readily confirm the synonymy. Material examined (56 specimens) Tasman Sea: 3 lots (SAMA), 4 specimens. North Atlantic: 1 lot (BMNH), 3 lots (USNM), 5 lots (ZMB), 4 lots (ZMUC), 26 specimens. South Atlantic: 1 lot (BMNH), 3 lots (ZMB), 10 specimens. North Pacific: 6 lots (LACM), 8 specimens. South Pacific: 1 lot (BMNH), 2 specimens. South Indian: 2 lots (SAM), 1 lot (ZMUC), 3 specimens. Red Sea (Gulf of Elat): 1 lot (USNM), 3 specimens. Diagnosis Body length up to 11 mm but usually less than 5 7 mm. Antennae 1 as long as head and first two pereonites; flagellum with dorsal margin relatively straight, ventral margin convex, rounded terminally. Gnathopod 2; carpal process less than halflength propodus. Pereopods 3 & 4; dactylus length about 0.7 x propodus. Pereopods 5 & 6; dactylus length about 0.2 x propodus. Pereopod 7; basis rectangular, width about 0.7 x length, about as long as ischium to carpus combined, with rounded posterodistal lobe extending to about midmerus. Lateral corners of last urosomite produced, partly overlapping peduncle of U 3. Uropod 3; peduncle slightly shorter than rami; sexual dimorphism of endopod not evident. Telson relatively large, circular, reaching a little beyond the middle of peduncle of U 3. Remarks A characteristic feature of this species is the very short carpal process of gnathopod 2 and the shape of the urosome. In the shape of the urosome, V. pyripes resembles V. longicarpus, but differs in most other respects. The shape of antennae 1 is similar to V. bovalli Bonnier, 1896, but that species is insufficiently known for a comparison.
