A new species of Speonemadus from Portugal, with the revision of the escalerai-group (Coleoptera, Leiodidae)

Abstract

Abstract. Over recent years, intense field work in caves of Portugal has provided new data on the distribution of subterranean Iberian leiodid beetles. Speonemadus algarvensis sp. nov. is described from caves of southern Portugal. The new species is included in the Speonemadus Jeannel, 1922 escaleraigroup (Cholevinae; Anemadini). All species of the S. escalerai-group are revised and S. breuili is resurrected as a valid species. A key to identify the species of the S. escalerai-group is provided and the distinctive characters are illustrated. The distribution of all species of the group is mapped with new data together with biogeographic considerations.

Heat tolerance and acclimation capacity in subterranean arthropods living under common and stable thermal conditions

“…Speonemadus angusticollis as a species cannot be considered as a true troglobiont because its populations in the central part of the Iberian Peninsula are endogean, that is, live in the soil or plant litter (Fresneda, ). In fact, although it has elongated body and appendages, this species does not show other typical morphological traits of cave‐adapted species such as a lack or reduction of eyes and wings or depigmentation (Fresneda, Grebennikov, & Ribera, ; Perreau, ; Reboleira, Fresneda, & Salgado, ). However, in its southern distribution (Andalusia region, including the present study site), S. angusticollis has been only found in caves, generally closer to the entrances.…”

Laboulbeniales hyperparasites (Fungi, Ascomycota) of bat flies: Independent origins and host associations

“…In this situation, opportunities exist for ascospores to be transmitted from a "typical" host to an "atypical" one. Such micro-habitats might be ant nests (Pfliegler, Báthori, Haelewaters, & Tartally, 2016), subterranean caves (Reboleira, Fresneda, & Salgado, 2017), or seaweed and plant debris on beaches (De Kesel & Haelewaters, 2014). Another type of specificity is displayed when a given fungus shows "a remarkable tendency to grow on very restricted portions of the host integument" (Benjamin & Shanor, 1952).…”

A molecular phylogeny of Speonemadus Jeannel, 1922 with description of two new species from Morocco (Coleoptera: Leiodidae: Cholevinae: Anemadini)

“…While the monophyly of the tribe is not well established, that of some of the subtribes, such as Anemadina, is generally accepted (Antunes-Carvalho et al in press). Anemadina includes two small genera in the Eastern Palearctic and Oriental regions, Anemadiola Szymczakowski, 1963 (four species) and the monotypic Cholevodes Portevin, 1928, plus two more diverse Palaearctic genera, Anemadus Reitter, 1885 (33 species) and Speonemadus (12 species) (Perreau 2000(Perreau , 2004Reboleira et al 2017). Jeannel (1922) established Speonemadus for a group of five Iberian species of Anemadus with a particularly slender body shape and modifications of the male protibiae, as well as other secondary sexual characters.…”

“…The genus Speonemadus was then defined by the presence of two series of sclerified denticles in the endophallus-in some species with a median denticle in ventral position-and the male protibia simple or with a carina. Subsequently to the revision of an additional Iberian species of the S. escalerai-group was described by Reboleira et al (2017) from Portugal. The authors also rehabilitated one Iberian species in the same group, S. breuili (Jeannel, 1922), considered to be a synonym of S. angusticollis (Kraatz, 1870) by .…”

“…The authors also rehabilitated one Iberian species in the same group, S. breuili (Jeannel, 1922), considered to be a synonym of S. angusticollis (Kraatz, 1870) by . The genus thus currently includes 12 species (Perreau 2004;Reboleira et al 2017) (Table 1), and almost as many synonyms (Perreau 2004), most of them established by .…”
