Dolichomacrostomidae

Dolichomacrostomidae is a family of small basal free-living flatworms of the clade Macrostomorpha. There are currently about 40 named species in this family.

== Description == Members of Dolichomacrostomidae are characterized by the presence of a tubular pharynx directed dorsocaudally and having a gland wreath with rhabdite glands. The brain is perforated by the ducts of the frontal glands, and the copulatory apparatus has a common gonopore for both male and female parts, with the female ducts open rostrally and the male ducts obliquely caudally into the common atrium. The male reproductive system has only one testis, which lies in front or at the same level as the ovaries.
