Giesbrecht, 1892
Females
Body of varying form, in some cases rather short and stout, in other cases comparatively slender; anterior Ce tends to be widest part of body. Ce separate from Pd1, anterior Ce unarmed or provided with 2 soft rostral filaments or R 1-2-pointed (Temoropia); Pd4 and 5 fused, partly fused or separate. Ur of 3-4 somites, CR of different structure in different genera, sometimes elongate. A1 24- or 25-segmented. A2 Enp more or less equal in length to Exp, Exp 6-7-segmented. Md with broad gnathobase with 1 large tooth set slightly apart from remaining teeth, Enp segment 1 often fused to Basis. Mx1 Li1 with 12-15 spines and setae, Li2 and 3 usually with 3 setae each (with 2 and 4 setae respectively in Temoropia setosa), Basis and proximal Enp segment often fused, Exp with 8-10 setae, Le2 with 1 or no setae, Le1 with 8-9 setae. Mx2 with Li1 and 2 with 4-5, 2-3 setae respectively, Li3 and 4 with 3 setae each, Li5 with 2-4 setae. Mxp of moderate size, may be slightly modified with recurved Enp or with fusion between Enp segments; Coxa with 2, 2-3, 2-3, setae, Basis with 0-3+2 setae, Enp with 2-4, 1-4, 1-3, 0-3+1, 4 setae respectively. P1-4 with the Enp 1-, 2- or 3-segmented; exopod segments 1 and 2 may be fused.
Spine and setal formula typically: Spine and seta Temoridae.
P5 not natatory, 2-3-segmented; usually without Enp; both Coxa fused with intercoxal sclerite to form common basal segment. Ovisac present in some cases.
Males
Segmentation of body and legs as in female except Ur of 5 somites. Right A1 distinctly geniculate. P5 not natatory, usually without Enp; larger than those of female and prehensile, often pincer-like on one side, 2-4-segmented with common basal segment.
It appears that this family now contains
Genus Epischura Forbes, 1882
Genus Eurytemora Giesbrecht, 1881
Genus Heterocope Sars, 1863
Genus Lamellipodia Schmeil, 1897
Genus Temora Baird, 1850
Genus Temoropia T. Scott, 1894
Temorites has been removed to the Bathypontiidae. Of the genera above, Temora and Temoropia are exclusively marine and are known to occur in the South Atlantic; Eurytemora is a brackish water genus; whereas Epischura, Heterocope, and Lamellipodia are found in lakes.
