Abstract—The subfamily Anataeliinae Burr, 1909 is restored in its original composition as one containing two genera: Anataelia Bolivar, 1899 and Challia Burr, 1904. Challiinae Steinmann, 1973, syn. n. is synonymized with Anataeliinae. Challia steineri sp. n. is described from Laos. “Anataelia” ramalhoi Sakai, 1996 described from Brazil is argued to belong to neither Anataelia nor Anataeliinae; it probably belongs to the subfamily Pygidicraninae. A detailed morphological redescription of A. canariensis Bolivar, 1899 is given. The history of the study, diagnoses, and possible apomorphies of the above-mentioned taxa are briefly discussed. The present wide distribution of Anataeliinae (the Canary Islands for Anataelia and East and South-East Asia for Challia) is apparently relict.

Despite more than a hundred years of active studies, the knowledge of the tropical fauna of earwigs is still far from being satisfactory. The same applies to the suprageneric classification of the order. In the present paper, a new species of the genus Challia is described, the composition of the subfamily Anataeliinae is reconsidered, and a hypothesis explaining formation of its range is proposed.
were described from Eastern China, Korea, Vietnam, and Laos (Nishikawa, 2006; Ho and Nishikawa, 2009). Two genera were originally included in the subfamily Anataeliinae Burr, 1909 [the initial spelling Anataelinae was corrected by Engel and Haas (2007)]: Anataelia and Challia (Burr, 1909). Such concept of the subfamily remained (Burr, 1911; Hincks, 1959) until Steinmann’s (1973) publication where the genus Challia was separated into the monotypical subfamily Challiinae Steinmann, 1973.
The genus Anataelia Bolivar, 1899 was described based on a single species, A. canariensis Bolivar, 1899 from Tenerife Island (Bolivar, 1899). Later, two dditional species from the Canary Islands were described (Martin and Oromi, 1988): A. lavicola Martin et Oromi, 1988 and A. troglobia Martin et Oromi, 1988. “Anataelia” ramalhoi Sakai, 1996 described from Brazil might not belong to this genus, being a Pygidicraninae (see below).
In the present study, the initial composition of the subfamily Anataeliinae, i.e., with two genera Anataelia and Challia included, is resurrected, and Challiinae is synonymized with Anataeliinae, which illustrates again an interesting example of a disjunct range: the Canary Islands on the one hand and East and South-East Asia on the other.
The genus Challia Burr, 1904 was also described based on a single species, Ch. fletcheri Burr, 1904 from Northeastern China
