Ordo: Araneae
Familia: Leptonetidae
Genus: Tayshaneta

Name

Tayshaneta concinna (Gertsch, 1974)Wikispecies linkPensoft Profile

Type data

Male holotype from Lost Gold Cave, 13 miles SW of Austin, Travis County, Texas, 27-May-1963, J. Reddell and B. Frank, 30.26N, 97.81W, (AMNH, examined).

Notes

Gertsch (1974)[1] included a single female specimen from Stark’s North Mine in Travis County as conspecific with Tayshaneta concinna although it is unclear which characters he based this decision upon. Stark’s North Mine is a unique feature in the Austin chalk formation and appears to be largely artificial, probably carved out by local residents. Recent inventories at the site have recovered additional Tayshaneta specimens, including adult males, which share the genitalic morphology of Tayshaneta concinna and are recovered as part of the concinna clade (Clade A, Fig. 4). Given the highly disturbed nature of the habitat, it is likely that Tayshaneta concinna also occurs on the surface. Although adult males are not available from the populations in Seibert Sink (Travis County) or County Line Bat Cave (Williamson County), molecular analyses support them as close relatives of Tayshaneta concinna and they are tentatively assigned to the species pending the discovery of males.

Diagnosis

Tayshaneta concinna may be separated from all Tayshaneta species that have a ventral sclerite, except Tayshaneta anopica, Tayshaneta oconnorae and T. sandersi, by the following combination of characters: male palpal tarsus undivided, tapering apically; male retrolateral tibial spine stout, sculptured throughout, length 0.4× tarsus length (RTS, Fig. 37B); embolus curved distally and with basal tooth (E, Fig. 37D). Separated from Tayshaneta anopica, Tayshaneta oconnorae and T. sandersi by being darkly pigmented with large eyes (Fig. 16A–C) and by the unique shape of the embolus (E, Fig. 37D).

Description

Complete description in Gertsch (1974[1]: 169–170). Habitus of male in Figs 16A–C, scanning electron micrographs of male palp in Figs 37A–F and female genitalia in Fig. 52F.

Distribution

Known from three caves in Travis County, Texas (Fig. 54).

Natural History

Individuals collected in Stark’s North Mine were found in small sheet webs at the base of chalk walls, rotting wood and breakdown material.
