Pattern and process: Evolution of troglomorphy in the cave-planthoppers of Australia and Hawaii ‒ Preliminary observations (Insecta: Hemiptera: Fulgoromorpha: Cixiidae), 2007, Wessel A. , Erbe P. , Hoch H.

The evolution of troglobites comprises three distinct problems: cave colonization by an epigean ancestor, the evolution of tro­glomorphies, and intra-cave speciation. The study of cave-dwell­ing planthoppers has contributed much to our understanding of troglobite evolution and provides useful model systems to test various aspects of the theoretic framework developed in re­cent years. Most promising in this respect are taxa with several closely related but independently evolved troglobiontic lineag­es, such as on the Canary Islands, in Queensland/Australia and on the Hawaiian Archipelago. Closely related species often oc­cur in caves with comparable ecological parameters yet differ in their age. Here we use comparative age estimates for Australian and Hawaiian cave cixiids to assess the dynamics of reductive evolutionary trends (evolution of troglomorphy) in these taxa and cave planthoppers in general. We show that the degree of troglomorphy is not correlated with the age of cave lineages. Morphological alteration may not be used to draw conclusions about the phylogenetic age of cave organisms, and hypotheses based on such assumptions should be tested in light of these findings.


A new species of cave adapted Nicoletiid (Zygentoma: Insecta) from Sistema Huautla, Oaxaca, Mexico: the tenth deepest cave in the world, 2008, Espinasa L. And Vuong N. H.
Anelpistina specusprofundi, n. sp., is described and separated from other species of the subfamily Cubacubaninae (Nicoletiidae: Zygentoma: Insecta). The specimens were collected in Sotano de San Agustin and in Nita Ka (Huautla system) in Oaxaca, Mexico. This cave system is currently the tenth deepest in the world. It is likely that A. specusprofundi is the sister species of A. asymmetrica from nearby caves in Sierra Negra, Puebla. The new species of nicoletiid described here may be the key link that allows for a deep underground food chain with specialized, troglobitic, and comparatively large predators such as the tarantula spider Schizopelma grieta and the 70 mm long scorpion Alaeran tartarus that inhabit the bottom of Huautla system.

A New Genus of the Subfamily Cubacubaninae (Insecta: Zygentoma: Nicoletiidae) from Caves in South-Central and Southwestern USA, 2010, Espinasa Luis, Furst Stephen, Allen Thomas, Slay Michael E.

The genus Speleonycta is erected, and S. ozarkensis, n. sp., is described and separated from other species of the subfamily Cubacubaninae. The type species was collected from several caves in the Ozark Plateau, while two more species, collected from a cave in Arizona and from a cave in California, remain under study. Morphology and preliminary analyses using histone DNA indicate that the new genus may be related to Texoreddellia, another nicoletiid from caves of Texas and northern Mexico.


A New Species of Nicoletiidae (Insecta: Zygentoma) from Kartchner Caverns State Park, Arizona, 2012, Espinasa L. , Pape R. B. , Henneberry A. , Kinnear Ch.

 

Speleonycta anachoretes, n. sp., is described and differentiated from S. ozarkensis, known from caves in the Ozark Plateau. The new species was collected from Kartchner Caverns State Park in Arizona. Morphology and preliminary analyses using 16S rRNA corroborate that Speleonycta may be related to Texoreddellia, another nicoletiid genus from caves of Texas and northern Mexico. General information regarding its conservation status within the commercial cave is provided


A new eyeless species of cave-dwelling trechine beetle from northeastern Guizhou Province, China (Insecta: Coleoptera: Carabidae: Trechinae), 2012, Tian Mingyi, Clarke Arthur

Qianaphaenops emersoni n. sp. is described from Gan Dong, a limestone cave in Yanhe Xian, northeastern Guizhou Province, China. Likely to be a narrow range endemic species, Q. emersoni is only known from two almost adjacent type locality sites in Gan Dong cave. Q. emersoni is the fifth species to be described in this genus of eyeless troglobitic trechine beetles, known only from caves in northeastern Guizhou; a distributional map of the genus Qianaphaenops Uéno is provided. Q. emersoni belongs to the Qianaphaenops tenuis species group which contains two described species: Q. tenuis and Q. rotundicollis (Uéno, 2000). Q. emersoni is very similar to Q. rotundicollis Uéno, but easily distinguished from the latter by its broader head and elytra, narrower pronotum and its more elongate and slender aedeagus. Some explanation of the exploration of Gan Dong is provided, along with habitat details of the trechine beetle Type Locality sites located approximately 950 metres into the cave. The subsequent discovery of an efflux cave, presumed to be the Gan Dong Resurgence, is also discussed.


A new record of Nicoletia phytophila (Nicoletiidae: Zygentoma: Insecta) from a cave in Belize, 2013, Espinasa Luis, Taylor Steven J, Espinasa Monica

The first cavernicolous Nicoletiidae (Insecta: Zygentoma) from The United Arab Emirates, 2013, Espinasa L. , Mendes L. F.

Lepidospora mazyadi, n. sp., is described and differentiated from all the other known Lepidospora s.s. The new species was collected from a cave in Jebel Hafeet in the United Arab Emirates. Morphology and preliminary analyses of 16S rRNA DNA sequences are described. The new species is unique because, unlike other species in the genus, it lacks sexually dimorphic terminal filaments. It is also the first nicoletiid reported from the United Arab Emirates and the second cave-adapted species from Arabia.
