– occurs in

equine. Note that the head is rounded in front. The antennae

are inserted well back so that the head forms a full semi-circle

in front of the base of the antennae.

Damalinia equi (syn. Bovicola equi, Trichodectes equi)

occurs in

sheep. Note that the head is rounded in front as in Damalinia

equi but the post-antennal region (temporal lobes) is narrower

than the pre-antennal region

Damalinia ovis (syn. Bovicola ovis, Trichodectes ovis)

affects goats. It is the most common biting louse of goats in the

Philippines. Note that the anterior margin of the head is

flattened or slightly concave. The pre-antennal angles are

expanded and somewhat pointed.

Damalinia limbata (syn. Bovicola limbata, Trichodectes limbata)

affects cats. Note that the lateral margins

of the pre-antennal regions are straight, converging anteriorly to

a strong apex with a distinct narrow emargination.

Felicola subrostrata

Damalinia bovis

Trichodectes canis

The members of this suborder are lice with antennae which are

clubbed and largely or entirely concealed in grooves on the underside

of the head. Maxillary palps may be present.
