Two new species of fungus gnats (Diptera: Mycetophilidae) from Kunashir Island, Kuril Islands

Abstract

Two new species of Mycetophilidae (Diptera), Clastobasis subalternans sp. n. and Phthinia kurilensis sp. n. are described from Kunashir I. (South Kuril Is.). Their relationships with other species of Clastobasis Skuse and Phthinia Winnertz are briefly discussed.

Two new Neuratelia Rondani (Diptera, Mycetophilidae) species from Western Palaearctic: a case of limited congruence between morphology and DNA sequence data

“…n. is very similar to Neuratelia caucasica , into which it also runs to in the key by Zaitzev (1994) because of having the foretibia slightly shorter than the fore basitarsus. Also the male terminalia of these two species are extremely similar, differ in details as follows: 1) paramers not expanded apically (Fig.…”

“…Following the key by Zaitzev (1994) the new species runs to Neuratelia sintenisi Lackschewitz, 1937, as its foretibia is usually shorter than fore-basitarsus. However, this character seems to be variable, as these are of equal length in one paratype, guiding to Neuratelia nemoralis , a species with so far reported Holarctic distribution (Laffoon 1965, Zaitzev 1994, but see specific discussion under the latter).…”

“…This is, however, challenged by Hutson et al (1980). Altogether 31 extant species are known from across the world including 16 species from the Palaearctic region (Matile 1974, Zaitzev 1994, Sasakawa 2004), 13 species from the Nearctic region (Borkent and Wheeler 2013) and one from both the Neotropical and Oriental regions (Bechev 2000). Additionally, three species have been described from fossils (Evenhuis 2014).…”

“…There are no keys to cover all described species of the world, of only the Palaearctic region or even just in Europe. For Western Palaearctic species, the most exhaustive one is the key by Zaitzev (1994) that excludes, however, several European species.…”

New and poorly known Palaearctic fungus gnats (Diptera, Sciaroidea)

“…Zaitzev 1994, Polevoi 2001). Sciophila larvae are mostly associated with fungal fruiting bodies, especially polypores, and most likely are spore-feeding (Jakovlev 2011) or may develop internally in fungus tissue (Zaitzev 1982). Three Boletina species are figured here and discussed; a review on the taxonomic status and ecology of the Holarctic species of the genus was recently provided (Salmela et al 2016).…”
