Clavigeritae (Coleoptera, Staphylinidae, Pselaphinae) of the Arabian Peninsula with the description of a new species of Corynotopsis Jeannel, 1951 from Oman.

Corynotopsisomanicussp. nov. of the myrmecophilous supertribe Clavigeritae is described from Oman. The type series was collected at night and the ant host species remains unknown. Corynotopsisscotti Jeannel, 1951 is newly recorded for Yemen, and Commatocerusconcinnus Besuchet & Cuccodoro, 2011 for Oman. Lasius Fabricius, 1804 and Lepisiota Santschi, 1926 are, for the first time, determined as hosts of the latter species. The problematic taxonomic status of Corynotopsisscotti is discussed. A distribution map of all Clavigeritae known from the Arabian Peninsula is provided.

First record of Systelloderes (Hemiptera: Heteroptera: Enicocephalidae) from Ecuador with a list of Ecuadorian Enicocephalomorpha.

The genus Systelloderes Blanchard, 1852 (Hemiptera: Heteroptera: Enicocephalomorpha: Enicocephalidae), has a nearly cosmopolitan distribution, with the greatest species richness being found in humid tropical and subtropical forests, but species are also present in humid microhabitats of temperate and arid zones (Wygodzinsky Schmidt 1991). In the Eastern Hemisphere species of Systelloderes occur in continental Africa (22 species, see Villiers 1969; 1976; Maldonado 1988; Banar 2008); Madagascar (Systelloders milloti Villiers, 1952); New Zealand (see Stys 1970, 2002) and New Caledonia (Systelloders loebli Stys Banar, 2007). Two species (S. capillicornis Bergroth, 1918 from Luzon and S. aetherius Bergroth, 1916 from Queensland) originally described as Systelloderes belong to the genus Henschiella Horváth, 1888 (P. Stys, unpublished data). As is frequently the case with Enicocephalomorpha, many species of Systelloderes remain to be described, especially from the Afrotropical, Neotropical and Oriental Regions. There are 13 described Systelloderes species from North and Central America (Wygodzinsky Schmidt 1991). To date, there are only six described species of Systelloderes from South America: two from Venezuela, and by a single species from Bolivia, Brazil, Chile and Peru each. There are very few additional records of Systelloderes in the New World tropics, including the works of Wolda (1975) and Ospina-Bautista (2018) on Colombia, Parker et al. (2012) on Peru, and Maestre et al. (2001) from Brazil.

The new species is described and illustrated, extensive comparative diagnoses for Xenicocephalus species are provided, and nomenclature, distribution, and biology of the genus are reviewed. The architecture of the raptorial forelegs of Xenicocephalus is unique among Enicocephalomorpha, and the genus is classified as subfamily incertae sedis.

The pregenital abdomen of Enicocephalomorpha and morphological evidence for different modes of communication at the dawn of heteropteran evolution.

The internal and external anatomy of the posterior metathoracic region, pregenital abdomen, and associated nervous system of the heteropteran infraorder Enicocephalomorpha are thoroughly described, using an array of state-of-the art techniques. Based on morphology, it is hypothesised which modes of communication these insects use. This study is based primarily on an undescribed species of Cocles Bergroth, 1905 (Enicocephalidae) and another undescribed species of Lomagostus Villiers, 1958 (Aenictopecheidae), but additional representatives of the infraorder are also examined. Our results are compared with the literature on other Heteroptera. The metathoracic scent gland system of Enicocephalomorpha uses the same muscles as that of more derived Heteroptera, although the efferent system is different. The presence of a tergal plate and well-developed longitudinal musculature in the families Enicocephalidae and Aenictopecheidae, as well as a sexually dimorphic set of sclerites and membranes that allow an as yet undetermined type of motion, may indicate the presence of vibrational signaling in the infraorder, although experimental confirmation is required. Our findings raise new research questions regarding heteropteran functional morphology and communication.
