{"title":"Structural megadiversity in leaf litter predators - the head anatomy of Pselaphus heisei (Pselaphinae, Staphylinidae, Coleoptera)","authors":"R. Beutel, Xiao-Zhu Luo, M. Yavorskaya, P. Jałoszyński","doi":"10.3897/asp.79.e68352","DOIUrl":"https://doi.org/10.3897/asp.79.e68352","url":null,"abstract":"The head anatomy of Pselaphus heisei (Pselaphitae) is described and documented. The structural features are evaluated in comparison with findings presented in earlier studies on the subfamily, with a special focus on correlations with predacious habits and the groundplan of Pselaphinae. We found the tentorium, labrum, maxillary palps, shape of head, and a system of dorsal pits and sulci highly variable within the subfamily, reflecting multiple transformations, including many homoplasious changes. The following major characters are identified as groundplan features of Pselaphinae: falciform mandibles; small mola; semiglobular neck; ventrolateral antennal articulation; steep clypeal region; setiform labial palpomere 3; tentorium with nearly vertical main branches and lacking laminatentoria; separation of tentorial bridge from tentorial arms; fusion of dorsal tentorial arms with the head capsule; large brain placed in the posterior third of the head; and a triple cluster of well-developed cephalic glands. The last feature supports a hypothesis that multiple and independent cases of adaptations to myrmecophilous habits observed in various lineages of Pselaphinae were possible by re-programming already existing glands to produce appeasement secretions. The cephalic muscle apparatus of P. heisei is similar to what is found in other staphylinoid groups, with some exceptions, whereas it is strongly modified in the myrmecophile Claviger testaceus. We propose that the unparalleled structural megadiversity in Pselaphinae is primarily linked with life in the upper soil layers combined with specialized carnivorous habits, with small and agile or mechanically protected arthropods as prey. Within the group, various specialized life habits have evolved, including myrmecophily, termitophily, and also life in deep soil or caves, each with unique morphological adaptations.","PeriodicalId":55460,"journal":{"name":"Arthropod Systematics & Phylogeny","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70395208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By applying an integrative taxonomy approach, we revealed and described a new species from Kyrgyzstan—Turanium losi Karpiński, Plewa & Hilszczański sp. nov. Distinguishing characters from closely related Turanium pilosum (Reitter, 1891) are presented and their ecological associations are discussed. The key characters, including the male terminalia, were examined by means of scanning electron microscopy. High-quality stacked photographs of the habitus of the specimens are presented for both species and their geographical distributions are mapped. While the new species shows stable morphological characters that allow its differentiation from T. pilosum and the COI genetic distance between them is approx. 3%, the different species delimitation methods gave discordant results. Although the new species remained unrecognized for so long, it seems that these cerambycids are common in the region and both can be considered potentially invasive as they are apparently highly polyphagous. It has also been documented that they occur sympatrically in Kyrgyzstan. Both the Bayesian and maximum likelihood analyses of COI sequences confirmed the monophyly of the genus Turanium with strong support (PP 1 and BS 90, respectively). Moreover, the recently revealed polyphyly of the tribe Callidiini was supported by our analyses and, consequently, the discussion on the establishment of a new tribe Ropalopini is raised. This study further corroborates the effectiveness of DNA barcoding as a tool in detecting new species and provides some of the first sequences for Central Asian cerambycids, which remain almost completely unknown in terms of molecular studies.","PeriodicalId":55460,"journal":{"name":"Arthropod Systematics & Phylogeny","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70394997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reproductive biology, including the mating behavior, ootheca rotation and deposition, and the embryonic development of a nocticolid cockroach Nocticola sp. were examined and described, and the phylogenetic issues regarding Nocticolidae and Blattodea were discussed. The abdominal terga II to IV are specialized in males, relating to the tergal glands, although they are less specialized in macropterous males. The (brachypterous) males display a wing-flapping behavior around the female before mating. The female delivers the ootheca with its keel upward, and several hours later, rotates it clockwise by 90° viewed from the female's side, into a horizontal position. After carrying the ootheca for a few days holding it by its flange, the female deposits it on the ground. The ootheca is pear-shaped, and contains only four eggs. About a dozen micropyles are localized on the posterior region of the ventral side of the egg. The aggregation of symbiotic bacteria (\"mycetome\") is not detected in the eggs. The embryo undergoes the blastokinesis of the \"non-reversion type,\" maintaining the original orientation in the egg. Similar to the recent combined and phylogenomic analyses, the information on the reproductive biology obtained in the present study, including the manner of handling of ootheca, mode of mating behavior, egg structure, and type of blastokinesis, may suggest close affinity between Nocticolidae and Corydiidae, thus the monophyletic Corydioidea.","PeriodicalId":55460,"journal":{"name":"Arthropod Systematics & Phylogeny","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69256726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
