• Male spicules are equal alength nd the gubernaculum is intricate
• Female amphidelphic

Sexually transmitted between cricket hosts. Infective dauer juvenile nematodes are transferred from male to female crickets during copulation. Adult female crickets harboring infective dauers subsequently transfer the nematode to their next mates. 

Adult nematodes occur primarily in the hindgut of mature male crickets, whereas juvenile nematodes are found in the genital chambers of mature male and female crickets
