 PLs; antesensillary ridges weakly developed, usually in- 

 apparent darita, n. sp. (p. 12) 



28(25) Scutum roughly pentagonal by virtue of being broadest at 

 PLs, and being angled here, and with lateral margins

crocidura (Radford, 1946) (=lancearia Radford, 1946) (p. 71) 

 30(28) PSB approximately 100 microns; PLs very short, only 

 about 17 microns in length ; with 8 usurped setae on scutum 



(fig. 189) rutila Gater, 1932 (p. 70) 



PSB greater than 116; PLs over 36 microns in length; 



usually with 6 usurped setae, rarely with 7 to 9 (fig. 53) 31 



31(30) Scutum more than twice as long as broad (fig. 29).
