“…Recently, however, Aldrich et al (2004a) indicated that a substantial population of cockroaches with the allozyme and molecular characteristics of C. wrighti have the same chromosome number as C. punctulatus ; they nonetheless considered this population C. wrighti . A recently published paper purporting to support the species definitions of Burnside et al (2000) with morphological data (Aldrich et al , 2004b) did not address this discrepancy, nor did it reconcile discordance with morphological data already in the literature ( e.g ., Fig. 7 in Nalepa et al, 1997).…”

Woodroaches of the genus Cryptocercus are subsocial and xylophagous cockroaches, distributed in North America and Asia. Studies on male chromosome number in Nearctic species have shown that diploid numbers vary from 2n=37 to 2n=47; numbers from Palearctic species were heretofore unknown. Two hypotheses have been proposed to explain the varying number of chromosomes among Nearctic species: the serial reduction hypothesis, and the parallel scenario. We performed phylogenetic analyses of the COII gene in these species and found evidence for the topology (47(45(43(39,37), which is congruent with the serial reduction hypothesis. We also determined chromosome numbers for the first time in Palearctic species, and found Cryptocercus primarius and Cryptocercus relictus to have relatively low chromosome numbers (2n=17-21) compared to their Nearctic relatives. Finally, our study determined the phylogenetic position of Cryptocercus primarius among other Asian taxa.

“…In addition to characterizing aspects of family group co-occurrence for the purpose of understanding sub-sociality, the present study also provides an opportunity to examine the adequacy of randomly sampling a single C. punctulatus individual per rotting log (e.g., Steinmiller, Kambhampati & Brock, 2001; Aldrich, Krafsur & Kambhampati, 2004; Aldrich, Zolnerowich & Kambhampati, 2004). Based on levels of genetic differentiation among co-occurring haplotypes seen here, the one-sample-per-log strategy would fail to fully capture within-log diversity about half of the time.…”

“…Given that copulation between adults likely takes place within the same gallery of the rotting log in which the pair later raise their family, mate pairs have been considered monogamous since opportunities for extra-pair copulation are few (but see Nalepa & Grayson, 2011). Although the spatial demarcation of family groups is difficult, sampling strategies employed in several molecular studies of C. punctulatus have used a single random sample (e.g., Steinmiller, Kambhampati & Brock, 2001; Aldrich, Krafsur & Kambhampati, 2004; Aldrich, Zolnerowich & Kambhampati, 2004). Depending on the question at hand, this may be adequate.…”

Genetic insights into family group co-occurrence inCryptocercus punctulatus, a sub-social woodroach from the southern Appalachian Mountains

The wood-feeding cockroach Cryptocercus punctulatus Scudder (Blattodea: Cryptocercidae) is an important member of the dead wood (saproxylic) community in montane forests of the southeastern United States. However, its population biology remains poorly understood. Here, aspects of family group co-occurrence were characterized to provide basic information that can be extended by studies on the evolution and maintenance of sub-sociality. Broad sampling across the species’ range was coupled with molecular data (mitochondrial DNA (mtDNA) sequences). The primary questions were: (1) what proportion of rotting logs contain two or more different mtDNA haplotypes and how often can this be attributed to multiple families inhabiting the same log, (2) are multi-family logs spatially clustered, and (3) what levels of genetic differentiation among haplotypes exist within a log, and how genetically similar are matrilines of co-occurring family groups? Multi-family logs were identified on the premise that three different mtDNA haplotypes, or two different haplotypes among adult females, is inconsistent with a single family group founded by one male–female pair. Results showed that of the 88 rotting logs from which multiple adult C. punctulatus were sampled, 41 logs (47%) contained two or more mtDNA haplotypes, and at least 19 of these logs (22% overall) were inferred to be inhabited by multiple families. There was no strong evidence for spatial clustering of the latter class of logs. The frequency distribution of nucleotide differences between co-occurring haplotypes was strongly right-skewed, such that most haplotypes were only one or two mutations apart, but more substantial divergences (up to 18 mutations, or 1.6% uncorrected sequence divergence) do occasionally occur within logs. This work represents the first explicit investigation of family group co-occurrence in C. punctulatus, providing a valuable baseline for follow-up studies.

“…Therefore, it is necessary to find new morphological characters to identify Anaplecta species. Although female genitalia were considered to have fewer useful morphological characters in the taxonomy of cockroaches, Aldrich et al (2004) successfully identified four Cryptocercus species based on female genitalia. Female genitalia have also been used in the identification of Cryptocercus (Wang et al 2015;Bai et al 2018).…”

Morphological characteristics, including male and female genitalia, combined with DNA barcodes were used to identify 470 Anaplecta specimens sampled from China. Ten Anaplecta species are new to science, including three cryptic species: A. paraomei Zhu & Che, sp. nov., A. condensa Zhu & Che, sp. nov., and A. longihamata Zhu & Che, sp. nov., which are distinguished mainly by their female genitalia. The other seven new species are as follows: A. bicruris Zhu & Che, sp. nov., A. spinosa Zhu & Che, sp. nov., A. ungulata Zhu & Che, sp. nov., A. anomala Zhu & Che, sp. nov., A. serrata Zhu & Che, sp. nov., A. bombycina Zhu & Che, sp. nov., and A. truncatula Zhu & Che, sp. nov. This study illustrates that differences in female genitalia can be used to distinguish among species of Anaplecta. The female genitalia of 19 Chinese Anaplecta species are described and illustrated in this paper.
