Eukoenenia mocororo (Palpigradi: Eukoeneniidae): a new troglobitic palpigrade from a Brazilian ferruginous cave.

A new troglobitic palpigrade from Southeastern Brazil is described based on nine specimens (including males, females and immatures of all stages) collected in an iron ore cave named "Mocororô". The most peculiar trait of Eukoenenia mocororo sp. nov.

A new species of the genus Gaucha Mello-Leito, 1924 from Minas Gerais, Brazil (Solifugae, Mummuciidae).

A new sun-spider species of the ibirapemussu species-group of the genus Gaucha is described based on males and a female collected in Southeastern Brazil. The newly described species can be readily distinguished from its congeners by the reduction of the cheliceral fixed finger, distal tooth (FD), closely positioned and smaller than the medial tooth (FM); the presence of cheliceral fixed finger profondal subproximal (PFSP) and retrofondal submedial (RFSM) teeth; and by the cheliceral movable finger, medial tooth (MM) well developed, larger than submedial tooth (MSM) and smaller than proximal tooth (MP). This is the thirteenth described species in the genus Gaucha, all known from South America.

A new troglobitic palpigrade from Central Brazil, with notes on a new opisthosomal character (Arachnida: Palpigradi).

A new species of palpigrade from the cave Gruta Cabeceira d'água in Goiás state in Central Brazil is described and illustrated based on 11 specimens: five adult males, two adult females, two immatures C and two immatures B. Eukoenenia audax sp. nov.

Three new cave-dwelling Eukoenenia (Palpigradi: Eukoeneniidae) from limestone caves in Northern Minas Gerais state, Brazil.

In this paper, we describe three new Eukoenenia species from specimens collected in limestone caves in the northern region of the Minas Gerais state, Brazil. These species present different degrees of adaptation to the subterranean habitat, with Eukoenenia magna sp. nov.

Eukoenenia ibitipoca: the first troglobitic Palpigradi (Arachnida) from a quartzitic cave.

Although the arachnids of the order Palpigradi are very common in subterranean habitats, no species has yet been recorded from siliciclastic caves. During a survey of cave invertebrates conducted in quartizitic caves in southern Minas Gerais state (Brazil), the occurrence of a new troglobitic palpigrade was revealed. Accordingly, in this paper we describe Eukoenenia ibitipoca sp.

A new locality of Koeneniodes madecassus Remy, 1950 (Palpigradi: Eukoeneniidae) in China, with the first complete redescription of a Koeneniodes species.

Koeneniodes madecassus Remy, 1950 is reported from Guangxi Province, Southwest China for the first time. Since there has been neither a Koeneniodes record nor any morphological addendum since 1997, several traits used in contemporary palpigrade taxonomy have remained unknown for this genus. Here, we redescribe K.

A new highly troglomorphic Loxosceles (Araneae: Sicariidae) from Brazil.

The spiders of the genus Loxosceles have been reported from caves in several regions of the world. Despite their commonness in subterranean habitats, the occurrence of troglomorphic species is quite rare. A new cave-dwelling species found in the Brazilian Caatinga can be included in the restricted list of troglomorphic Loxosceles by presenting the following troglomorphic traits: eyes with reduced diameter, absence of pigment around the eyes, appendage elongation and pale coloration.

Spelaeobochica goliath (Arachnida: Pseudoscorpiones: Bochicidae), a new troglobitic pseudoscorpion from Brazil.

Spelaeobochica goliath sp. n., found in a limestone cave located in the municipality of Ibiracatu (Minas Gerais, Brazil), is described.

Two new troglobiotic palpigrades (Palpigradi: Eukoeneniidae) from Brazil.

Two new species of troglobiotic Brazilian palpigrades are described: Eukoenenia jequitinhonha sp. n., found in Lapa do Córrego do Vieira cave (Caraí, Minas Gerais) and E.

Two new species of the enigmatic Leptokoenenia (Eukoeneniidae: Palpigradi) from Brazil: first record of the genus outside intertidal environments.

Two new species of Leptokoenenia Condé 1965 (Eukoeneniidae: Palpigradi), Leptokoenenia pelada sp. nov. and Leptokoenenia thalassophobica sp.
