Taxonavigation

Ordo: Araneae
Familia: Leptonetidae
Genus: Tayshaneta

Name

Tayshaneta myopica (Gertsch, 1974) – Wikispecies link – Pensoft Profile

Type data

Male holotype from Tooth Cave, Travis County, Texas, 30-March-1965, J. Reddell, 30.40N, 97.85W, (AMNH, examined).

Notes

Tayshaneta myopica was listed under the Endangered Species Act in 1988 (U. S. Fish and Wildlife, 2010) due to its extremely limited distribution in a rapidly urbanizing area outside of Austin, Texas. Recent work has been directed at refining the distribution of the species in order to set recovery goals and several additional localities were discovered during the course of this study (Fig. 56). Of special interest are caves near the type locality which share identical mitochondrial and nuclear DNA haplotypes (Tooth Cave, Root Cave, Gallifer Cave and Tight Pit) suggesting that individuals move between sites.

Diagnosis

Tayshaneta myopica may be separated from all other Tayshaneta species, except Tayshaneta paraconcinna, by having an elongate ventral sclerite (VS, Fig. 44E) and a broad spoon shaped embolus (E, Fig. 44D). Separated from Tayshaneta paraconcinna by having the embolus sharply projecting ventrally (Fig. 44D) and having a recurved, but not sickle-shaped, retrolateral tibial spine (RTS, Fig. 44A).

Description

Complete description in Gertsch (1974[1]: 169–170). Habitus of male and female in Figs 23A–F, scanning electron micrographs of male palp in Figs 44A–F and female genitalia in Fig. 53F.

Distribution

Known from caves in Travis and Williamson Counties, Texas (Fig. 57).

Natural History

Individuals in Geode Cave and Tooth Cave were observed suspended beneath sheet webs at the bases of stable rocks and breakdown material (Figs 2A, 2C). When disturbed, individuals would drop from their webs and fold their legs in a protective posture similar to that reported for Calileptoneta (Ledford, 2004).
