SYNOPSIS. Six species belonging to the amphipod family Stegocephalidae Dana, 1855 (Crustacea) are redescribed and 
figured. Seven new species are also described: Andaniexis americana sp.novy., A. gloriosa sp.nov. and A. pelagica sp.nov., 
Andaniopsis africana sp.nov., Stegocephaloides boxshalli sp.nov., S. calypsonis sp.nov. and S. ledoyeri sp.nov. The type 
material of Stegocephaloides attingens K.H. Barnard 1916 comprises two species, S. attingens and S. boxshalli sp.nov. 
Stegocephaloides calypsonis is formally described for the first time, but was originally described in the PhD thesis of Anton 
Galan (1984). 
sequently, for a number of stegocephalid species, there is consider- 
able confusion in terms of morphology, generic and specific status.

INTRODUCTION 
Many species in the amphipod family Stegocephalidae Dana, 1855 
were described at the end of the 19" or the beginning of the 20" 
century. These descriptions usually took the form of a limited 
descriptive text accompanied by very few figures, typically showing 
only one or two diagnostic characters. Very few of these species 
have been later redescribed in any detail, and when they have, the 
description was usually based on new material without any refer- 
ence to the type material (e.g. Barnard, 1962, 1964; Ledoyer, 1986; 
all referring to Andaniexis australis K.H.Barnard 1932). Con-

(UK) include type material of nine stegocephalid species, none of 
which has ever been redescribed from the type material. Three of 
these species belong to the genus Andaniotes Stebbing, 1897; which 
have recently been dealt with elsewhere (Berge, 2001a.). In the 
present paper, the type material of six species is redescribed and 
figured: Andaniexis australis K.H.Barnard, 1932, Bathystego- 
cephalus globosus (Walker, 1909), Phippsia gibbosa (Sars, 1883), 
Phippsiella rostrata K.H.Barnard, 1932, Stegocephaloides attingens 
K.H.Barnard, 1916 and S. australis K.H.Barnard, 1916. In addition
