Four specimens were examined from the syntypic series oiA.pamaguemis, 

 all currently deposited at NMW. The largest of these (NMW 47837), a 233 mm SL 

 male, is designated the lectotype. The remaining specimens, therefore, become 

 paralectotypes (NMW 47832 and NMW 47838 [2]). 



Two syntypes of A. porphyreus were examined; the largest of these (ANSP 

 8388, female, 235 mm SL) is designated the lectotype, and the smaller specimen 

 (ANSP 8389, 159 mm SL) the paralectotype.
