Name

Tisentnops mineiro Brescovit & Sánchez-Ruiz, 2016 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile

Types

Male holotype from Gruta da Serra da Moeda (20°19'58"S, 44°03'10"W), Moeda, Minas Gerais, Brazil, X.2005, R.L. Ferreira, deposited in IBSP 191293; female paratype from Gruta MP-10 (20°15'58"S, 43°53'16"W), Itabirito, Minas Gerais, Brazil, IX.2007, R.L. Ferreira, deposited in IBSP 191294.

Etymology

The specific name is the designation for the native people from the state of Minas Gerais, Brazil, where this species was found.

Diagnosis

Tisentnops mineiro sp. n. is easily separated from other species of the genus by the absence of eyes (Figs 1A, 17A).

Description

Male (holotype). Total length 3.6. Carapace 1.6 long, 1.2 wide. Coloration: cephalothorax orange reddish. Palps yellow. Legs yellow, except coxae I-II orange-reddish. Abdomen uniformly yellow-white. Eyes absent of setae with elongated bases forming a row on the anterior margin of the endites, infrequent on the sub-marginal part (Fig. 1B). Leg measurements: I: femur 1.3/ patella 0.6/ tibia 1.1/ metatarsus 0.6/ tarsus 0.6/ total 3.7; II: 1.1/ 0.6/ 1.0/ 0.5/ 0.4/ 3.6; III: 0.9/ 0.4/ 0.6/ 0.6/ 0.4/ 2.9; IV: 1.1/ 0.6/ 1.1/ 0.8/ 0.7/ 4.3. Sockets bases of setae elongate on leg I forming an asymmetric row on the ventral margin of the femur and the tibia (Figs 1C, J). Palpal cymbium twice the length of the bulb, embolus short and curved, half the length of the bulb (Figs 1D–F; 4A–C).
Female (paratype). Total length 3.8. Carapace 1.7 long, 1.2 wide. Coloration: cephalothorax and legs orange, except legs III-IV yellow and external border of endites brown. Abdomen grayish. Palpal endites as in male, but with fewer sub-marginal modified sochets (Fig. 1I). Leg measurements: I: femur 1.1/ patella 0.5/ tibia 0.9/ metatarsus 0.5/ tarsus 0.4/ total 3.4; II: 1.0/ 0.5/ 0.7/ 0.5/ 0.4/ 3.1; III: 0.8/ 0.4/ 0.5/ 0.6/ 0.5/ 2.8; IV: 1.2/ 0.5/ 0.9/ 0.8/ 0.5/ 3.9. Internal female genitalia with a triangular anterior margin of the hyaline membrane that covers transverse sclerotized bars, an elongate membranous anteromedian receptaculum with a wide base, and a transverse, enlarged, V-shaped dorsal fold (Figs 3G–L, 4D–E).

Distribution

Known only from the state of Minas Gerais, southeastern Brazil (Fig. 18A–B).

Natural history

All 79 specimens (7♂, 24♀, 48 immature) of Tisentnops mineiro sp. n. were collected in 33 caves distributed in rock outcrops in rupestrian fields found in mountain peaks of the Atlantic Forest and lowland areas of regenerated forest or grasslands. Unlike Tisentnops onix sp. n. from limestone caves, Tisentnops mineiro sp. n. was only found in iron caves. Additionally, Tisentnops mineiro sp. n. was found in palaeoburrows “Paleotoca” (natural shelter of extinct mammals, e.g. Giant Armadillos, see Bittencourt et al. 2015[1], figs 5–6) in Cave AP-38 in the municipality of Santa Bárbara. Tisentnops mineiro sp. n. were found on the ground, under rocks in aphotic zones with high relative humidity (≥ 98%). Tisentnops mineiro sp. n. is a troglobite spider restricted to caves from target mining areas and regions of iron formations with high economic interest.
