“…Among the invertebrate detritivores, wood-feeding Cryptocercus cockroaches contribute significantly to the breakdown of coarse woody debris (Nalepa et al 2002). Members of this taxon are also excellent model organisms for reconstructing landscape history, particularly in the Appalachian Mountains (Nalepa et al 2002;Garrick 2011), and they are a key group for understanding early evolution of termites (Klass et al 2008).…”

In this paper, genetic evidence for local cooccurrence (syntopy) between members of two chromosomal races within the Cryptocercus punctulatus species complex from the Southern Appalachian Mountains is presented. This phenomenon has not previously been detected, despite extensive sampling and numerous molecular studies of this the sub-social wood-roach spanning the past 20 years. The incidence of syntopy seems rare; it was detected in one of 70 rotting logs sampled across eight states in the southern United States. However, the location where it occurs could become a key focus of research aimed at resolving taxonomic uncertainty in this group.

“…In Nearctic regions, they show a disjunct distribution in the USA; Cryptocercus clevelandi is distributed in the Coast and Cascade Mountains of northern California and southwestern Oregon (Nalepa et al 1997), while Cryptocercus punctulatus species complex, also described as Cryptocercus darwini, Cryptocercus garciai, Cryptocercus punctulatus and Cryptocercus wrighti by Burnside et al (1999), is reported to occur along the Appalachian and Allegheny Mountains (Burnside et al 1999;Nalepa et al 2002). In Palearctic regions, Cryptocercus has been reported in only a few forests of Southwest China and Northeast Asia including Korea, Manchuria and Siberia (Bey-Bienko 1950;Grandcolas 2000;Grandcolas et al 2001;Nalepa et al 2001;Park et al 2004).…”

“…Thus, the causes and dynamics that shape their present-day distribution have been the subject of vigorous discussion over the last decade, associated with their taxonomic status as well as phylogeography (Burnside et al 1999;Nalepa & Bandi 1999;Grandcolas 1999aGrandcolas , 1999bClark et al 2001;Nalepa et al 2002;Park et al 2004). …”

“…In karyotype analysis, four variants (male 2n037, 39, 43, 45) were found in C. punctulatus species complex in the southern Appalachian Mountains of eastern North America, and none of the variants occurs in the same locality, displaying different distribution range (Burnside et al 1999;Nalepa et al 2002).…”

“…According to two evolutionary scenarios of the variants suggested by Nalepa et al (2002), the karyotype variants might have evolved independently from an ancestral population without having sequential events to one another (parallel scenario), or they might have been decreased sequentially from the ancestral karyotype (sequential scenario). As in the recent studies using karyotype and mtDNA markers (Everaerts et al 2008), further molecular survey for these geographic isolates may provide clues to better understanding of the evolutionary trend of the genus Cryptocercus related to the molecular sequence evolution.…”

Park (2013) Evolutionary trend of the small subunit nuclear ribosomal DNAs (SSU rDNAs) of wood-feeding Cryptocercus cockroaches (Blattaria: Cryptocercus), Animal Cells and Systems, 17:1, 36-43, DOI: 10.1080/19768354.2012 The objective of this study is to elucidate the evolutionary rate of Cryptocercus SSU rDNAs based on the relative rate test (RRT) and comparative analysis of the primary sequences. In the RRTs, the evolutionary rate differences (dKs) of the Cryptocercus SSU rDNAs were not statistically significant (0.107 BP B0.996) in all cases, although an Asian Cryptocercus appeared to evolve more slowly than a North American Cryptocercus as indicated by the negative signs of dKs. Contrary to the RRT, the comparative analysis of SSU rDNA sequences revealed some interesting aspects in the evolutionary rates of Cryptocercus SSU rDNAs. In comparison with those of closely (Mastotermes darwiniensis and Tenodera aridifolia) or more distantly related taxa (Locusta migratoria), the SSU rDNAs of the genus Cryptocercus showed that insertions are progressing in a variable region (HV2). The SSU rDNA of Calymmaderus punctulatus species complex (Mountain Lake Biological Station, VA), a North American species, was unusually more elongated in the HV2 than those of the reference taxa or the other congeneric species.

The eastern subterranean termite, Reticulitermes flavipes , currently inhabits previously glaciated regions of the northeastern U.S., as well as the unglaciated southern Appalachian Mountains and surrounding areas. We hypothesized that Pleistocene climatic fluctuations have influenced the distribution of R. flavipes , and thus the evolutionary history of the species. We estimated contemporary and historical geographic distributions of R. flavipes by constructing Species Distribution Models (SDM). We also inferred the evolutionary and demographic history of the species using mitochondrial (cytochrome oxidase I and II) and nuclear (endo‐beta‐1,4‐glucanase) DNA sequence data. To do this, genetic populations were delineated using Bayesian spatial‐genetic clustering, competing hypotheses about population divergence were assessed using approximate Bayesian computation (ABC), and changes in population size were estimated using Bayesian skyline plots. SDMs identified areas in the north with suitable habitat during the transition from the Last Interglacial to the Last Glacial Maximum, as well as an expanding distribution from the mid‐Holocene to the present. Genetic analyses identified three geographically cohesive populations, corresponding with northern, central, and southern portions of the study region. Based on ABC analyses, divergence between the Northern and Southern populations was the oldest, estimated to have occurred 64.80 thousand years ago (kya), which corresponds with the timing of available habitat in the north. The Central and Northern populations diverged in the mid‐Holocene, 8.63 kya, after which the Central population continued to expand. Accordingly, phylogeographic patterns of R. flavipes in the southern Appalachians appear to have been strongly influenced by glacial‐interglacial climate change.
