Schizurakrops meesi gen. et sp. nov. urn:lsid:zoobank.org:act: A99E05AD-A910-483E-B6EE-B03FB5C839DE Figs 54–57 Diagnosis Based on adult female only. All features as in generic diagnosis. Rostrum reaching beyond antennal scale. Eye rudiments with strong tooth-like anterior projection extending beyond basal segment of antennular trunk; this segment without ventral carina. Antennal sympod with three teeth near disto-lateral edge; median segment of peduncle five times as long as basal segment; scale length four times as long as maximum width. Blade-like extension of clypeus proceeds anteriorly between antennae up to end of second segment of antennular trunk. Uropods without spine. Telson trapezoid not considering terminal incision. Terminal incision ⅐ of telson length, lined all along with densely-set, slender laminae. Lateral margins distally converging; basal 3/10 bare except for small stand-alone spine at ⅕ of telson length from basis; distal 7/10 with discontinuous series of large spines with 1–2 small spines in between; large spines increasing in length distally. Each disto-lateral lobe with two spines, outer spine ⅔ length of incision, inner spine ⅓. Telson with total of ≈ 34 spines and ≈ 35 laminae, no setae. Etymology The species name is a noun with Latinized masculine ending in genitive singular, dedicated to Jan Mees in recognition of his important contributions to the taxonomy and ecology of mysids.
