Table 4. — Armature of thoracic legs I and II of the female of Hatschekia brevira- 



mus, new species 



distinct principally in nature of armature of antennule and thoracic 

 legs. 



2. H. ostracii Yamaguti, 1953: Similar in body shape and in 

 the presence of the processes at the base of the antennae. H. brevi- 

 ramus differs from this species in having 6, not 7, segments in the 

 antennule, the processes at the base of the antennae are not as large, 

 the caudal rami are tipped by 2 setules, while there are 5 in iJ. ostra- 

 cii. The endopodite of the fu'st thoracic leg is 2-segmented in H. 

 ostracii and 1-segmented in H. breviramus; H. ostracii also has a 

 rudimentary thh*d thoracic leg which is not present in H. breviramus. 



3. H. cadenati Nunes-Ruivo, 1954: The thoracic leg armature 

 is similar although the caudal rami of H. cadenati, in addition to 

 other body parts, differ, having 5 setae and setules instead of 2 as in 

 H. breviramus. 



4. H. bodiani Nunes-Ruivo, 1954a: This species, like H. ostra-cii 

 Yamaguti, 1953, has the projections at the base of the antennae that 

 are present in H. breviramus. The maxilliped armature is also similar 

 but the 2 species differ, most distinguishably in the armatm-e of the 

 caudal rami and thoracic legs. 



5. H. cluthae (Scott, T., 1902): Similar in reduced armature of 

 first thoracic leg, differs firstly in having 2-segmented endopodite on 

 the first thoracic leg, secondly in having a more distinct abdomen, 

 different armament on maxilliped, and general body shape. 



The species name "breviramus" is derived from the Latin words 

 "brevis" (short) and "ramus" (branch) and refers to the short caudal 

 ramus.
