“…1). However, Sakai (1971, 1982, 1985, 1996) considered the differences in the virgal morphologies (1 vs. 2 gonopores) important and recognized Cylindrogastrinae and Diplatyinae as distinct subfamilies within Diplatyidae. Steinmann (1975, 1986, 1989b) proposed Diplatyinae and Cylindrogastrinae as subfamilies of the family Pygidicranidae (Tab.…”

Based on samples collected during surveys of Brazilian cave fauna, seven earwig species are reported: Cylindrogaster cavernicola Kamimura, sp. n., Cylindrogaster sp. 1, Cylindrogaster sp. 2, Euborellia janeirensis, Euborellia brasiliensis, Paralabellula dorsalis, and Doru luteipes, as well as four species identified to the (sub)family level. To date, C. cavernicola Kamimura, sp. n. has been recorded only from cave habitats (but near entrances), whereas the other four organisms identified at the species level have also been recorded from non-cave habitats. Wings and female genital structures of Cylindrogaster spp. (Cylindrogastrinae) are examined for the first time. The genital traits, including the gonapophyses of the 8th abdominal segment shorter than those of the 9th segement, and venation of the hind wings of Cylindrogastrinae correspond to those of the members of Diplatyidae and not to Pygidicranidae. This is the first synopsis of cave-dwelling earwigs of Brazil, one of the most species-rich areas of Dermaptera in the world.

“…The inclusion in the analyses of the Italian species of Pseudochelidura (P. galvagnii Vigna Taglianti, 1999, and P. orsinii (Gené, 1833)) might shed some additional light on whether Eulithinus should remain as a valid genus or if, alternatively, it should be transferred to Pseudochelidura. Even Steinmann (1979Steinmann ( , 1981 (1975), followed by Sakai (1992Sakai ( , 1996 and Herrera Mesa (1999) included them in the subfamily Allodahliinae Verhoeff, 1902. Steinmann (1975 considered that the criterion "border on the sides of the elytra" given by Verhoeff (1902), which also served to describe Allodahlia Verhoeff, 1902, was a sufficiently important characteristic feature to elevate the group to the rank of subfamily.…”

“…But the taxonomic position of the species was controversial since then. The taxon was included subsequently in the genera Chelidura Latreille, 1825 (type species: Forficula aptera Mégerlé, 1825) by Dubrony (1878), Lithinus Burr, 1909 (type species: Forficula analis Rambur, 1838) by Burr (1909), Eulithinus Hincks, 1935 (replacement name for Lithinus) by Hincks (1935), Pseudochelidura Verhoeff, 1902 (type species: Forficula sinuata Germar, 1825) by Burr (1908) and Steinmann (1981), and Eulithinus again by most modern authors (e.g., Ebner 1959;Steinmann 1975Steinmann , 1984Harz & Kaltenbach 1976;Sakai 1992Sakai , 1996Herrera Mesa 1999;Pérez-Valcárcel et al 2022). The genus Lithinus, and its replacement name Eulithinus, were created to include only the Sierra Nevada earwig (Burr 1911;Hincks 1935), and although all recent authors retained the genus Eulithinus as valid, there is a long-standing controversy on its phylogenetic position.…”

“…Most of the authors dealing with Sierra Nevada earwigs, included them in the subfamily Forficulinae Latreille, 1810, or Anechurinae Burr, 1907. However, Steinmann (1975, followed by Sakai (1992Sakai ( , 1996 and Herrera Mesa (1999) included them in the subfamily Allodahliinae Verhoeff, 1902, a subfamily previously considered to be restricted to eastern Asia (Srivastava 1993). To complicate matters, Steinmann (1981Steinmann ( , 1984Steinmann ( , 1989Steinmann ( , 1993, after a series of taxonomic inconsistencies involving Sierra Nevada earwigs (see García-París 2017 for the problems in Anisolabididae Verhoeff, 1902) described a second taxon within the genus Eulithinus: Eulithinus montanus (Steinmann, 1981), also endemic to Sierra Nevada.…”

Since the description of Eulithinus analis (Rambur, 1838) the taxonomic position of this Sierra Nevada endemic earwig has been controversial. It has been subdivided in different taxa, assigned to various genera or transferred to different subfamilies. With the aim of clarifying its systematics, we performed a mitochondrial phylogeographic analysis using specimens from different localities of Sierra Nevada representing the diverse phenotypes treated as differentiated taxa until now, and a phylogenetic analysis including representatives of apparently distant, but morphologically close, relatives. The phylogenetic and phylogeographic results obtained using mitochondrial (cytb, cox1) and nuclear (ITS2) markers and the study of morphological characters, indicate that the Sierra Nevada Mountain Range harbors a single species of the genus Eulithinus. Based on these molecular data, the morphological characters used to date in the internal taxonomy of this group of earwigs, especially size and shape of the cerci, lack diagnostic validity and show a large inter- and intra-populational variability. These results imply the synonymy of Eulithinus montanus (Steinmann, 1981) with Eulithinus analis (Rambur, 1838) syn. nov. and the reconsideration of Eulithinus analis outside the subfamily Allodahliinae. We established the synonymy between Eulithinus analis (Rambur, 1838) and Forficula brevis Rambur, 1838 syn. nov., a name that must be removed from the synonymy of Forficula decipiens Gené, 1832.

“…Diplatyidae ( sensu Sakai 1996, including Haplodiplatys and Cylindrogastrinae) is an earwig family comprising approximately 150 described species. This family shows typical Gondwanan distribution (Popham 2000), possessing many plesiomorphic characteristics (Haas 1995; Haas and Kukalová-Peck 2001; Haas and Klass 2003; Klass 2003).…”

Description of a second South American species in the Malagasy earwig genus Mesodiplatys from a cave habitat, with notes on the definition of Haplodiplatyidae (Insecta, Dermaptera)

The genus Mesodiplatys (Dermaptera: Diplatyidae) comprises eight species from Madagascar and one species from Peru. Based on a sample collected from a cave in Brazil, a new species of this genus, Mesodiplatysfalcifer Kamimura, sp. n., is described as the second species from South America. Based on a reexamination of the holotype of Mesodiplatysinsularis, a revised key to Mesodiplatys species is provided. The definitions of the genera Mesodiplatys and Haplodiplatys and the family Haplodiplatyidae are also reconsidered.
