Chuneola paradoxa

by monotypy. The unique
type
, a juvenile measuring just less than
7 mm
(judging by Woltereck’s drawing) could not be found in any major European museum and is considered lost. Fortunately, this is a very distinctive species readily distinguished by Woltereck’s description and figure. The

Diagnosis.
As with the characters of the family.
Three species.
Sexual dimorphism.
Sexual dimorphism is not very marked in
Chuneola
. Apart from the fact that females have oostegites and males have small genital papillae the main difference seems to be that females have a slightly more inflated pereon.
Remarks.
This is a very distinctive genus, unlike any other in the superfamily. Unusual characters of note are the relatively large mouthparts, the lack of a mandibular palp and molar, the relatively shorter first antennae with only two small articles terminal to the callynophore, the reduced second antennae, the partly retractile dactyls of the gnathopods and the spoon-shaped formation and retractile dactyls of pereopods 3 & 4. The structure of the mouthparts provides a link to the
Scinoidea
but most of the other characters are more aligned with the
Lanceoloidea
.
