13 A row of 3 verY closelY approximated rounded prensisetae on medial margin of each surstylus. Left pregonite greatly enlarged and sclerotized, forming a long, black, pointed projection ( Fig. 7). Phallus U-shaped, divided into three processes apically ( Fig. 8) ................................................................................. S. andasibe View in CoL
