Head, eyes ovate. Antenna 1 shorter than antenna 2; peduncular articles 1 and 2 not enlarged, not articulate; accessory flagellum absent. Antennae 1–2 calceoli present, apparently gammarid ( +type +1). Antenna 2 peduncular article 1 not enlarged. Maxilla 1 basal endite (inner plate) setose along medial margin. Maxilla 2 coxal endite (inner plate) with oblique setal row. Body laterally compressed. Gnathopods 1–2 subchelate. Pereopods heteropodous. Pereopod 4 with well-developed posteroventral lobe. Pereopods 5–7 merus and carpus expanded; dactylus long (more than half length of propodus), with short setae along posterior margin. Pereopod 5 coxa equilobate. Uropods 1–2 rami with short apical robust setae. Urosomites 1–3 free. Uropod 3 biramous; rami styliform; endopod subequal in length to exopod.

It differs significantly from +Bathyporeiidae +as follows: mandible incisor dentate, curved (smooth, straight in +Bathyporeiidae +); molar triturative (non-triturative in +Bathyporeiidae +); maxilla 2 coxal endite with oblique setal row (oblique setal row absent in +Bathyporeiidae +); gnathopod 1 similar in form to gnathopod 2 (dissimilar in +Bathyporeiidae +); pereopods heteropodous (homopodous in +Bathyporeiidae +); pereopods 5–7 with broadened merus-carpus (narrow in +Bathyporeiidae +), dactyli long with setae along posterior margins (short, without setae in +Bathyporeiidae +); uropod 3 outer ramus 1-articulate (2-articulate in +Bathyporeiidae +), inner ramus subequal in length to outer ramus (inner ramus minute in +Bathyporeiidae +). + + +Without using strongly apomorphic characters such as the +type +1 calceolus, apical setation of uropod 3 rami, pereopod 7 with setae along posterior margin the Zaramillidae is quite similar to the + +Gammaridae +Latreille, 1802 + +. This may be an artefact based on the high amount of morphological variation in the gammarids. They differ in significant characters such as: antenna 2 peduncular article 1 not enlarged in zaramillids (enlarged, bulbous in +Gammaridae +); labium inner lobes well developed (vestigial or absent in +Gammaridae +); pereopod 5 with coxa equilobate (with small anteroventral lobe in +Gammaridae +); pereopods 5–7 broad (narrow in +Gammaridae +), dactyli long with setae along posterior margins (dactyli generally short with few or no setae along margins); urosomites without dorsal setae (with small robust setae on urosomites 1–2 +Gammaridae +). + +In fact Zaramillidae does not appear to have any close family affinities within the Gammaridira. + + + \ No newline at end of file
