abstract = {Mengenillidae is a small, basal family of Strepsiptera,
mainly characterized by free-living females in contrast to
the endoparasitic females of Stylopidia. Here, we describe
external and internal structures of the female abdomen of
Eoxenos laboulbenei (Mengenillidae). The external morphol-
ogy was examined and documented using microphotography.
Internal structures were reconstructed three-dimensionally
using a μCT-data set. The morphologically simplified abdo-
men comprises 10 segments. The integument is weakly
sclerotized and flexible. Spiracles are present
dorsolaterally on segments I–VII. Segment VII bears the
posteroventral birth opening and the small abdominal segment
X carries the anus at its apex. Numerous eggs float freely
in the hemolymph. The musculature of segments I–IV is
composed of ventral and dorsal longitudinal muscle bundles,
strongly developed paramedial dorsoventral muscles and a
complex meshwork of small pleural muscles, with minimal
differences between the segments. Segments V–X contain
more than 50 individual muscles, even though the musculature
as a whole is weakly developed. Even though it is not
involved in processing food, the digestive tract is
well-developed. Its pos- tabdominal section comprises a part
of the midgut and the short hindgut. The midgut fills a
large part of the postabdominal lumen. The lumina of the
midgut and hindgut are not connected. Five or six nodular
Malpighian tubules open into the digestive tract at the
border region between the midgut and hindgut. The birth
organ below the midgut releases the primary larvae after
hatching via the birth opening at segment VII. It is likely
derived from primary female genital ducts. The presence of
six additional birth organs of segments I–VI are de novo
formations and a groundplan apomorphy of Stylopidia, the
large strepsipteran subgroup with endoparasitic females. The
loss of the primary birth organ of segment VII is an
apomorphy of Stylopiformia (Stylopidia excl. Corioxenidae).},
