Genus Geomonhystera
Andrássy, 1981
Monhysteridae. Body length between 0.6 and 1.2 mm. Cuticle
smooth but in the inner level often finely striated. Somatic stetae numerous.
Labial papillae setiform, cephlic setae articulate, fairly strong, 10 in
number. Ocelli not present. Mouth cavity similar to that of
other monhysterids, sometimes with some very small thickenings, (denticles).
Rectum strikingly thick, heavily muscular, longer than in other members
of the family. Vulva far back, at 80% of the body length, quite near
to the anal opening. Spicules slightly curved, gubernaculum short,
simple. Tail relatively short and stout, hardly tapering posteriorly,
manyfold as long as the vulva-anus distance. Tail spinneret short.
Contrasted with the other genera of the family, the species of Geomonhystera
are definitely terrestrial nematodes. They occur especially often
in moss and under bark. Under unfavourable circumstances they drop
off to anabiotic sleep.
