The ectosome contains very abundant isochelae and is supported by underlying styles. The choanosome is partly a unispicular reticulation and partly there are ascending paucispicular tracts of two to four spicules connected by single spicules. Ascending tracts of styles are the length of one choanosomal style apart, penetrate the ectosomal membrane and cause the hispidation.</paragraph>
