Lanceola clausi pirloti Shoemaker, 1945 (Fig. 17) 



Shoemaker, 1945a: 212 (pro sp.); Vinogradov, 1964: 112. 

 Length of sexually mature specimens 12-16 mm. 

 L. clausi pirloti basically differs from the typical form in that the 

 2nd segment of pereopods I is highly broadened, pereopods III-IV are 

 stronger, and pereopods VI are relatively longer. 

 71 Notes: Based on the differences noted above, Shoemaker (1945a) 



identified L. pirloti as an independent species, but a review of abundant 

 material revealed that these differences are variably expressed or only 

 some discernible. Thus individual specimens could actually be included 

 with certitude under L. pirloti while others occupy an intermediate posi- 

 tion between L pirloti and L. clausi. The wide variability of L. clausi 

 reveals variation in several features, including those that served as the 

 basis for identification of an independent species, L. pirloti, by Shoe- 

 maker. Evidently, there is no adequate justification for such an identi- 

 fication and L. pirloti should be considered a subspecies of the highly 

 variable L clausi.
