Figure 27 .—?Penaeopsis rectacuta. . 31 mm cl, S of Timor 

 Island, Timor Sea. Thelycum, ventral view. Scale = 2 mm. 



collected in the Timor Sea by O. A. Petrov during 

 a cruise of the RV Lira. There is little doubt in 

 my mind that the males are members of P. recta- 

 cuta. The female, except for the thelycum, also 

 possesses features typical of P. rectacuta. In the 

 thelycum the anterior border of the plate of ster- 

 nite XIV is considerably more inclined posterolat- 

 erally than in typical females. The anterior part of 

 the median ridge is uniquely divided by a groove, 

 and the bulbous posterior part is larger and over- 

 laps the thoracic ridge. Finally, the posteromedian 

 projection of sternite XIII is considerably larger 

 than in any specimen of P. rectacuta examined by 

 me. A bopyrid isopod was found in the branchial 

 chamber of this specimen; it might have been re- 

 sponsible for these peculiar features of the female 

 genitalia. 



Commercial importance. — Although no estimates 

 of the economic importance of this species have 

 been recorded, it has been cited among the com- 

 mercially exploited shrimps of the Philippines by 

 Domantay (1956), and as of economic value 

 throughout its range by Holthuis and Rosa (1965).
