Extract

The genus Heterococcus was erected by Ferris (1918) for a new species. H. arenae Ferris, having 9-segmented antennae, a denticle on the claw and with the normal trilocular pores replaced by quinquelocular pores. Other species were added later and Morrison (1945) discussed the genus at some length and described in detail three other related genera.
