Remarks.
Sieg (1982)
redescribed this species based on an adult female with oostegites (
paratype
: No. 2026/ 51). Examination of Menzie’s types showed a few errors in Sieg’s redescription.
Sieg (1982)
illustrated the pereopod 6 dactylus as smooth but it has a subterminal seta, or aesthetasc.
Menzies (1953)
described the dactylus as being apically bifid in the original description, but this appearance is due to the presence of a short subterminal seta. The seta on the ventrodistal corner of the pereopod 1 basis was observed as being smooth; whereas,
Sieg (1982)
illustrated it as being pectinate.
Menzies (1953)
did not describe or illustrate the basis. The
holotype
has an antenna with eight articles in the flagellum but Sieg described the adult female
paratype
as having seven. Examination of the juvenile
paratype
(=
allotype
Menzies, 1953
) also revealed the presence of seven articles, so this character apparently exhibits ontogenetic variation.
Kalliapseudes viridis
can be distinguished from its other congeners by the following combination of characteristics: 1) the anterolateral corners of pereonites 2–4 with apophyses, 2) one long seta on the ventrodistal corner of the pereopod 1 basis, and 3) a spinulate process on the third peduncle article of the antenna.
