Troglocaris anophthalmus

Troglocaris anophthalmus is a species of freshwater shrimp in the family Atyidae. It lives in karstic caves in Bosnia and Herzegovina, Croatia, Italy and Slovenia.[1] Although morphologically similar across its 500-kilometre (310 mi) range, molecular phylogenetics suggests that there are four or five cryptic lineages with more restricted ranges, although one such lineage does range unusually widely for a troglobite – over 300 kilometres (190 mi).[3]

Synonyms [2]
  • Palaemon anophtalmus Kollar, 1848 (incorrect original spelling)
  • Palaemon anophthalmus Kollar, 1848
  • Troglocaris Schmidti Dormitzer, 1853

Like other underground-living animals, this shrimp lacks pigment (appearing whitish) and eyes. The carapace length is typically about 0.5–0.9 cm (0.20–0.35 in).[4]

It was originally described by Vincenz Kollar as Palaemon anophtalmus (a misspelling of "anophthalmus"), but this name was considered to be a nomen nudum for a long time. This name is, however, accompanied by a description, and predates Dormitzer's junior synonym Troglocaris schmidtii.[2]
