Diagnostic description.
Body subcylindrical. Eyes absent. Antennae 1–2 calceoli absent. Antenna 1 slightly longer than antenna 2; peduncular article 1 longer than article 2; article 2 longer than article 3; article 3 shorter than article 1; peduncular articles 1–2 not geniculate; accessory flagellum absent. Antenna 2 peduncular article 1 enlarged, bulbous. Mandible molar triturative; palp symmetrical. Maxilla 1 basal endite apically setose; palps symmetrical. Maxilla 2 basal endite without oblique setal row. Labium inner lobes vestigial or absent.
Coxal gills on pereopods
2–6, stalked (with proximal restriction or complete suture);
sternal gills present
, simple; sternal blisters absent.
Gnathopod 1
subchelate; similar in males and females (not sexually dimorphic);
larger (or stouter) than gnathopod 2
; propodus palm with single row of simple robust setae along palmar margin. Gnathopod 2 subchelate; similar in males and females (not sexually dimorphic); carpus not produced along posterior margin of propodus, projecting between merus and propodus. Pereopods 3–4 not sexually dimorphic. Pereopod 4 without posteroventral lobe.
Pereopod 5
shorter than pereopod 6;
coxa without lobes
. Pereopod 7 longer than pereopod 5. Pleonites 1–3 without dorsal carinae. Urosomites 1–3 free; with slender or robust dorsal setae. Urosomite 1 with large distoventral robust seta. Urosomite 2 with pair of dorsal concavities each with 1–3 small setae. Uropod 1 without basofacial robust setae. Uropod 3 not sexually dimorphic; biramous, without plumose setae; endopod minute.
Telson entire
; dorsal or lateral robust setae absent; apical robust setae present.
Habitat.
Freshwater, hypogean.
Included genera.

Remarks.
Messouli
et al
. (2007) alluded to the possibility that kotumsarids might be crangonyctidirans and our phylogenetic results indicate they are.
