Abstract

Anelpistina levidensis n. sp. (Insecta: Zygentoma: Nicoletiidae) from the cave of Naj Tunich, Petén, Guatemala is described. The new troglobitic species differs from other described species by its long and slim appendages.

... The species richness and composition found in this study are unprecedented for Guatemala. Previous studies focused mostly on descriptions of new species and thus failed to showcase the broad diversity of invertebrate species in Guatemalan caves (Barr, 1973;Gertsch, 1973;Schultz, 1977;Platnick & Pass, 1982;Rodriguez & Hobbs Jr, 1990;Espinasa & Zhuang, 2009;Viana & Ferreira, 2019) with rare exceptions (Mitchell & Reddell, 1973;Reddell, 1981;Reddell & Veni, 1996). ...

Several studies have tried to elucidate the main environmental features driving invertebrate community structure in cave environments. They found that many factors influence the community structure, but rarely focused on how substrate types and heterogeneity might shape these communities. Therefore, the objective of this study was to assess which substrate features and whether or not substrate heterogeneity determines the invertebrate community structure (species richness and composition) in a set of limestone caves in Guatemala. We hypothesized that the troglobitic fauna responds differently to habitat structure regarding species richness and composition than non-troglobitic fauna because they are more specialized to live in subterranean habitats. Using 30 m 2 transects, the invertebrate fauna was collected and the substrate features were measured. The results showed that community responded to the presence of guano, cobbles, boulders, and substrate heterogeneity. The positive relationship between non-troglobitic species composition with the presence of guano reinforces the importance of food resources for structuring invertebrate cave communities in Guatemalan caves. Furthermore, the troglobitic species responded to different substrate features when compared to non-troglobitic species. For them, instead of the presence of organic matter, a higher variety of abiotic microhabitats seem to be the main driver for species diversity within a cave. The high specialization level of troglobitic organisms might be the reason why they respond differently to environmental conditions. The findings of this study highlight the importance of biological surveys for understanding cave biodiversity and give insights on how this biodiversity might be distributed within a cave. Conservation measures should keep in mind the target organisms and if such measures aim to protect a broad variety of organisms, then one should aim to preserve as many microhabitats and trophic resources as possible.

A new troglobitic nicoletiid species (Cubacubana parkerae) is described from specimens collected in a cave in Hidalgo, Mexico. The pedicellus of the male in this species is distally enlarged on the posterior side, almost creating a lobe.

Relationships within the subfamily Cubacubaninae, the dominant subfamily of Nicoletiidae in America, are appraised based on parsimony analysis of 20 morphological characters and sequence data from five loci (nuclear 18S and 28S rRNA, mitochondrial 16S rRNA, nuclear protein coding gene histone H3, and mitochondrial protein coding gene cytochrome c oxidase subunit I). The data, analyzed under direct optimization for a range of analytical parameter sets, indicated that species may show some biogeographical structure. It also indicated that the presence of articulated submedian appendages on urosternum IV is not a valid discriminating character in taxonomy. Species within the traditional genera Anelpistina, Cubacubana and Neonicoletia were found to belong to a group in which no clear morphological or molecular distinction was present. It is proposed that members of these three genera should be united within a single taxon. On the contrary, the genus Prosthecina is well supported by the data. © The Willi Hennig Society 2006.
