Diagnosis (from Kaderka 2015): Bistriopelma differs from all other theraphosid genera, except the genus Phrixotrichus Simon 1889 (sensu Perafan & Perez-Miles 2014a) and the troglobite
species Tmesiphantes hypogeus Bertani, Bichuette & Pedroso 2013 by having two abdominal dorsolateral patches of the type III urticating setae, each with a stripe of long pale to reddish-brown thicker setae, arranged diagonally to the longitudinal body axis.
(obligate cave inhabitant) Phanetta subterranea is nearly ubiquitous in Indiana caves and Porrhomma cavernicola is equally widespread, but more sporadic in occurrence.
The species seems to be a troglobite
which lives in the MSS and the adjacent caves, it was not found in surrounding epigeic environments.
Animals occurring in these nutrient-starved ecosystems have strange names such as "troglobite
," "stygobite," "trogloxene" and "troglophile." Troglobites
and stygobites are cave-adapted (troglomorphic) animals .
The chronicles of speleological exploration -- leading the Princess of Thailand through Tham Lod, and BBC film crews in search of troglobite
fish -- made me want to set out for subterranean adventures myself.
hirsuta as a true troglobite
and classified it as a troglophile.
recurvata was the first aquatic troglobite
to return to the Cedars after organic pollution (Culver et al., 1992).
This new taxon differed from known species, except the genus Phrixotrichus Simon 1889 (sensu Perafan & Perez-Miles 2014) and the troglobite
species Tmesiphantes hypogeus Bertani, Bichuette & Pedroso 2013, in the presence of two abdominal dorsolateral patches of the type III urticating setae.
burnsorum, a troglobite
occurring in caves of the Mosquito Creek drainage in Harrison County.
Three of these species were transferred to Troglochernes, a genus originally named for a peculiar troglobite
- According to Barr (1963), cave-dwelling organisms are generally separated into four categories: (1) Troglobite
(obligate cavernicole, usually specialized in various ways); (2) Troglophile (facultative cavernicole able to complete entire life cycle within caves, but can also be found in other similar habitats); (3) Trogloxene (habitually inhabit caves or other similar habitats but must return to the surface or near the cave entrance for food), or (4) Accidental (accidental entrants into caves surviving for a "relatively" short time).
