A new troglomorphic species of Larca (Pseudoscorpiones, Larcidae) from Colorado

Mark S. Harvey, David B. Steinmann

Research output: Contribution to journalArticlepeer-review


A new species of Larca is described from dry habitats in a cave in central Colorado. Like other cave-dwelling species of Larca, the new species Larca boulderica sp. nov., shows relatively modest morphological adaptations, such as pale colouration and slightly elongated appendages, compared with their epigean counterparts. This species is the sixth cave-dwelling species of Larca described from North America and, like other cave-dwelling Larca in North America and Europe, tends to be distributed in more southerly regions.
