Family CYPRIDINIDAE Baird, 1850

 

Introduction

A phylogenetic analysis of the family is presented in Cohen & Morin, 2003.

 

Diagnosis

Carapace length varying from about 1 mm to 32 mm; surface usually smooth but ornate in some forms; posterior evenly rounded or with caudal processes or siphon; incisure always present, but not slit-like with dorsal margin overlapping ventral margin as in Cylindroberidinae. First antenna: both d- and e-bristles on 8th segment well developed; b- and c-bristles on adult male with suctorial discs. Second antenna: length of exopodal segments similar in males and females, segments usually with basal spines; endopod 1–3-segmented in female, in males usually similar. Mandibula: coxal endite usually well developed; exopod also well developed. Maxilla: coxale and precoxale with thin transparent epipodal appendages with hirsute margin; 3rd endite present; exopod well developed with 3 bristles; 1st endopodal segment with sclerotised cutting edge on posterior distal corner. Fifth limb: 3 segments present, protopod with elongate sclerotised process on posterior distal margin; exopod: 1st segment with main tooth generally consisting of 6 teeth and proximal peg; 2nd segment without large tooth. Sixth limb: limb consisting of several bristles in place of epipodal appendage, 4 segments, and end segment; posterior end of end segment usually not extending markedly past segments. Seventh limb: similar in male and female, with variation in number of bristles and types of end combs. Rod-shaped organ: generally short, bulbous, or peglike; never elongate. Furca: each lamella with 4 to 28 claws.

Subfamily Azygocypridininae Kornicker, 1970

 

Diagnosis

Carapace large (4–15.5 mm), oval in lateral view with small rostrum and incisure, without caudal process; ornamentation lacking except for minute punctae; anterior, ventral, and posteroventral sections of selvage present, parallel and just within outer edge of valve; posterodorsal selvage present on list. Each lamella of furca with 18–28 claws; lateral eyes flaplike, without ornamentation.

Note: the generation of this complete preview for CYPRIDINIDAE Baird, 1850 was cancelled at Isocypridina fallax Kornicker, 1996 owing to the initation of another complete preview for Stiphidion facetum Simon, 1902. Only one complete preview may be executed at a time. Previews were generated for 6 of 69 taxa.
