NO, 9 manning: Atlantic stomatopod Crustacea 7 



The genera Hemisquilla and Odontodactylus, each known from a 

 single species in the western Atlantic, are not represented in the col- 

 lections herein reported. H. braziliensis (Moreira, 1903) is known 

 only from southern Brazil, in the waters off Rio de Janeiro (Lemos 

 de Castro, 1955). O. havanensis (Bigelow, 1893) was reported from 

 Curasao by Rathbun (1919) and Holthuis (1941) and has a wide 

 horizontal and vertical distribution, from the Bahamas and the Gulf 

 of Mexico to Curaqao, in 0-163 fms (Manning, 1959). 



Genus Parasquilla, new genus 



Diagnosis: Dorsal surface of body roughened; rostral plate with a 

 wide longitudinal groove on anterior half; antennal protopod with one 

 ventral papilla; carapace rounded anterolaterally and posterolaterally, 

 reflected marginal carinae present on posterior third only; cervical 

 groove distinct across dorsum of carapace; last three exposed thoracic 

 somites with submcdian and intermediate carinae; sixth and seventh 

 thoracic somites with a distinct lateral process; epipods present on 

 first five thoracic appendages; mandibular palp present; raptorial claw 

 short, heavy, dactylus armed with three teeth; propodus grooved for 

 reception of dactylus, with three movable spines on inner, proximal 

 margin, and a row of pectinations on upper margin; dorsal ridge of 

 carpus with two strong teeth; merus grooved inferiorly throughout its 

 length; inner branch of walking legs strap-shaped, two-segmented; 

 first five abdominal somites with nine longitudinal carinae; six carinae 

 on sixth abdominal somite; telson without prelateral lobes, with six 

 strong posterior teeth, the apices of the submedian teeth movable ; four 

 to nine, usually nine, minute movable submedian denticles, two fixed 

 intermediate denticles, and one lateral one; dorsal surface of telson 

 with a sharp crest, flanked on either side by a converging row of pits; 

 dorsal carinae, in addition to the carinae of the marginal spines, may 

 be present; basal prolongation of uropod produced into three subequal 

 teeth, the outer much the longest. 



The name Parasquilla means "beside Sguilla," and is derived from 

 the Greek para meaning "beside" or "wrong in," and the generic name 

 Sguilla, from the Latin scilla and Greek skilla, meaning shrimp. The 

 gender of the generic name is feminine.
