Manningia Serfene, 1962, p. 20. — Manning, 1963, p. 313. 



Definition. — Size moderate, TL 90 mm or less; body smooth, 

 depressed but compact; eyes of moderate size, cornea bilobed, set 

 very obhquely on stalk, outer margin of stalk longer than inner; 

 rostral plate usually pentagonal, apical spine present or absent; 

 antennal protopod with papillae; carapace narrowed anteriorly, 

 unarmed, cervical groove indicated on lateral plates only; carapace 

 with marginal carinae, not reflected, along posterior margins of lateral 

 plates; thoracic somites with at most 1 pair of lateral dorsal carinae, 

 lateral margins of sLxth and seventh somites rounded; eighth thoracic 

 somite with low, short, median ventral keel; 5 epipods present; man- 

 dibular palp present; propodi of last 3 thoracic appendages as long 

 as or longer than broad, that of last appendage with ventral brush 

 of setae; raptorial claw stout, dactylus armed with 4 teeth, outer 

 margin of dactylus with strong basal notch; propodus stout, fully 

 pectinate, with 3 movable spines at base, proximal one longest; 

 dorsal ridge of carpus divided into 2 strong teeth; merus stout, much 

 shorter than ischium, with or without inferodistal spine; endopods of 

 walking legs 2-segmented, elongate; abdomen depressed, smooth, 

 second to fourth somites each with obscure longitudinal lateral grooves; 

 fifth and sLxth abdominal somites carinate, sLxth with 3 paus of dorsal 

 spines; telson much broader than long, with median carina and 5 

 pahs of lateral carinae on dorsal surface; submedian teeth of telson 

 with bases appressed, apices movable; submedian denticles absent, 

 2 broad intermediate denticles and 1 broad lateral denticle present, 

 outer intermediate and lateral denticle each with ventral spinule; 

 basal segment of uropod with dorsal and lateral carinae, dorsal ter- 

 minating in distal spine; distal segment of exopod longer than prox- 

 imal; endopod elongate; basal prolongation produced into 2 spines, 

 inner longer, with or without intervening lobe; inner margin of basal 

 prolongation with spinules. 



Type-species. — Pseudosquilla pilaensis de Man, 1888, by mono- 



typy. 



Discussion. — Within the Pseudosquilla complex of genera including 

 Pseudosquilla, Pseudosqmllopsis, Parasquilla, Alanningia, Coronidop- 

 sis, Eurysquilloides, and Eurysquilla, discussed by Manning (1963), 

 Manningia seems to be most closely related to Coronidopsis Hansen. 

 Both of these genera share an eye with bilobed cornea and an outer
