myrmecophylic habits in this genus. The punctulation of the head in 
Coecopria might be explained as mimicry of the host ants. The dense 
pilosity within the horseshoe-shaped fold on the great sternite may 
be explained as a source of an attractive exudate licked by ants. The 
formation of the mouth parts (reduction of palpi, opisthognathous 
mandibles) together with the strong reduction of eyes might indicate 
that the species of Coecopria are fed by ants. The absence of males 
in material of Coecopria suggests thelytoky as a possible mode of 
reproduction.
