This paper is the first in a series describing the previously unstudied cave spiders from Cyprus. Two new species, Dysderocrates kibrisensis sp. n. and Harpactea kalavachiana sp. n., are described. Detailed morphological descriptions and diagnostic characteristics are presented. This is the first report of the genus Dysderocrates Deeleman-Reinhold & Deeleman, 1988 from Cyprus.

The spider fauna of Cyprus, the third largest island of the Mediterranean, is poorly studied. One-hundred-fifteen species have been reported from the island (
To fill this gap, we have begun a survey of the spider fauna of the island. Here we present our findings from previously uninvestigated caves. We found two new species of the dysderid genera Dysderocrates and Harpactea, and describe them based on females. Males were not sampled because they are only present for a short time in populations and because of the relatively low densities of cave spider populations in general.
Spider samples were collected from Beşparmak (Pentadactylos) and Saray (Palace) Caves (Fig.
Our specimens were preserved in 70% ethanol. Digital images of the copulatory organs were made with a Leica DFC295 digital camera attached to a Leica S8AP0 stereomicroscope. Between 5–15 photographs were taken at different focal planes and combined using Combine ZP (

Dysderocrates kibrisensis sp. n. can be differentiated from D. silvestris Deeleman-Reinhold, 1988 (spherical spermatheca) and D. storkani (pentagonal-shaped spermatheca) by the transverse spermatheca. The new species differs from D. regina by its longer spermatheca and triangular dorsal arch (Da, Fig.

Seven species of Dysderocrates are known, and the entire genus is restricted to the Mediterranean Basin. We placed this species in Dysderocrates because it fits the diagnosis: large body size, three strong teeth on the cheliceral groove, and many spines on the anterior femora. Dysderocrates kibrisensis sp. n. is the first and only species of the genus reported from Cyprus.

Harpactea is the second largest genus of the Dysderidae with 181 named species. Most Harpactea species have six well-developed eyes, although several cave-dwelling species exhibit different levels of eye reduction. Harpactea sanctidomini Gasparo, 1997 (Tremiti Islands, Italy) has only four eyes, with the PME entirely reduced. Harpactea persephone Gasparo, 2011 (Kournas Cave, Chania Prefecture, Crete, Greece), H. karaschkhan Kunt et al., 2016 (Yalandünya Cave, Gazipaşa, Antalya, Turkey), H. stalitoides Ribera, 1993 (Iberian Peninsula), and H. strinatii Brignoli, 1979 (Diros Caves, Peloponnese, Greece) are eyeless.
The eyes of H. kalavachiana sp. n. are reduced, and the AME are distant from each other, much more than average (Fig.

The results of our study increase the number of dysderid species on Cyprus from seven to nine, which increases the entire spider fauna to 117. Because the distributions of the two new species are limited to their type localities and because most cave species have small distributions, it is very likely that they are endemic to Cyprus.
Our arachnological sampling on the island continues. Future additional samples, including males of these two new species, will help determine their generic position more precisely.
