Remarks.
The family
Microparasellidae
was ambiguously established by
Karaman (1933)
without formally stating family name anywhere in that publication. On the same occasion, the author described two new species of
Microparasellus
, namely
Microparasellus puteanus
Karaman, 1933 and
Microparasellus stygius
Karaman, 1933, but without designation of the type species for the genus
Microparasellus
, and without providing the name of the new family. One year later,
Karaman (1934)
formally proposed the family name
Microparasellidae
for the new family, also giving a family diagnosis and assigned two genera to the family: the then monotypic
Microparasellus
Karaman, 1933 (
Microparasellus puteanus
) and transferring
Microparasellus stygius
Karaman, 1933 to the new genus
Microcharon
Karaman, 1934 together with
Microcharon latus
Karaman, 1934 described in the same paper (
Karaman 1934
).
