AUSTRALIAN CUMACEA. No. 12! 
THE FAMILY DIASTYLIDAE (PART 2) GYNODIASTYLIS 
AND RELATED GENERA 
By HERBERT M. HALE, DIRECTOR, SOUTH AUSTRALIAN MUSEUM 
Summary 
A few Diastylids have been described which are separated from all others by the facts 
that while the female third maxilliped lacks an exopod the male has no trace of 
pleopods. Species previously known to have these characters in combination have 
been placed in three genera, Gynodiastylis Calman, Allodiastylis Hale and Dic 
Stebbing; the female is unknown in the genotype of the last-named but as stated by 
Zimmer (1914, p. 192) it seems undoubtedly very close indeed to Gynodiastylis.
