MORGAN and PROVENZANO DEVELOPMENT OF SQUILLA EMPUSA LARVAE AND POSTLARVA 



FR;URE 20.— Squilla cmpusa. A-E: 

 stage VTII, first to fifth pleopods re- 

 spectively. 



lantic species of stomatopods, the identity of Fax- 

 on's larva will remain uncertain. 



To identify larvae of S. empusa the spinules of 

 the carapace and denticles of the telson should be 

 examined. Stages I and II possess four spinules on 

 the lateral margin of the carapace and four inter- 

 mediate denticles. The third to ninth stages are 

 armed with six spinules on the lateral margin of 



the carapace. There are two anterior and three 

 posterior spinules all ventrally directed, and one 

 median spinule laterally directed. The telsons of 

 stages III to IX have S to 10 mtermediate denti- 

 cles. 



Except for Provenzano and Manning (1978), 

 who reared Gonadactyius oerstedii from hatching 

 to metamorphosis, experimenters who have at-
