Taxonomic notes.

Little is known about Brazilian lithobiomorph taxonomy. All specimens examined here belong to Lamyctes ( Henicopidae ), a diverse genus with around 42 species distributed worldwide. In Brazil, only two species have been observed: L. adisi Zalesskaja 1994 and L. emarginatus (Newport, 1844). The former is endemic to Manaus and only found in Tarumã-Mirim Igapó of the Rio Negro region ( Adis 1992, Zalesskaja 1994, Foddai et al. 2002). The latter is an exotic species, now widely distributed in Brazil in addition to being known from Europe, North America, Greenland, Tasmania, and New Zealand.

Distribution.

Only a few records of lithobiomorphs are available for Brazil in the literature, mainly stemming from the Amazonian and Atlantic Forests in the southeast. Bücherl (1942) described sightings of Lithobius forficatus (Linnaeus, 1758) in Bahia state. This species was originally identified by Brölemann (1909). However, Bücherl (1942) suggests that the specimen in that publication was not L. forficatus , but an unknown introduced lithobiomorph. Here, we recorded Lamyctes specimens in several caves from Pará, Mato Grosso, Bahia, Minas Gerais, and São Paulo.

Habitat.

The genus appeared common in caves of different lithologic characteristics, including limestone, quartzitic, iron, and sandstone, but was preferentially found in limestone caves; no sightings have been recorded for granitic caves. This preference is corroborated by additional records of unidentified lithobiomorphs in limestone caves from Minas Gerais and São Paulo in southeastern Brazil ( Gnaspini-Netto 1989, Gnaspini and Trajano 1994, Trajano 1987, Trajano and Gnaspini-Netto 1991a, Pinto-da-Rocha 1995). Certain substrates also seem to be preferred, specifically guano piles, wet clay, or wet vegetal debris. This observation suggests that the genus either favors wet organic substrates (possibly because their potential prey also occurs in such habitats) or is intolerant to dry substrates.
