Esser, Jens, 2018, First record of a native Atomaria S, 1829 (Coleoptera: Cryptophagidae) from the Neotropical Region, Linzer biologische Beiträge 50 (1), pp. 225-228 : 225-227

Atomaria schmidli nov.sp.

Typ e material: Holotype ♂ : " Ecuador, 3.10.2007, Cajanuma , Paramo , Prov. Loja, 3000 m NN, barkspray, J. Schmidl" [ MFNB]. Paratypes: 1 ex. with the same data as the holotype [cES] ; 1 ex.: " Ecuador, 29.09.2008, Cajanuma , Paramo , Prov. Loja, 3000 m NN, barkspray, J. Schmidl" [cES] ; 1 ex.: " Ecuador, 1.10.2008, Cajanuma , Paramo , Prov. Loja, 3000 m NN, barkspray, J. Schmidl" [cES] ; 2 ex.: " Ecuador, Prov. Loja , Cajanuma 3000 m NN, Podocarpus NP, barkspray 2009 / 01.09." [cES] ; 1 ex.: " Ecuador, Prov. Loja , Cajanuma 3000 m NN, Podocarpus NP, barkspray 2009 / 07.09." [cES] .

Et y m o l o g y: The specific epithet points on Jürgen Schmidl (Nuremberg), who collected all specimens.

De s c r i p t i on: Male, 1,7 mm, hind wings well developed. Brown, covered sparsely the yellow hairs, hairs decumbent. Legs and antennae somewhat lighter (some specimens are dark brown). Antennae slender with club not well developed, segments 9, 10 and 11 little broader than 7. Segments 2, 3, 4, 5, 6 and 8 smaller, segment 1 broader. Segment 1 long, slightly curved. Space between antennae less broad as segment 1 long ( Atomaria s. str.). The tip of segment 1 is reaching the eyes. Legs slender and without any features. Head with eyes relatively extended but not convex. Pronotum with rounded margin, broadest behind the middle. Margin before the middle more straight, behind the middle rounded. Pronotum moderately punctate, with puncture diameter of the same size of the distance between the puncture. Elytra elongate, somewhat broader than pronotum. Puncture on elytra (on basal third) like on pronotum .

Co mm e n t: The new species resembles to a few nearctic species, e. g . Atomaria nigricollis CASEY, 1900, A. patens CASEY, 1900, but it is well distinguished by its slen- der antennae with clubs slightly separated. The nearctic Atomaria need revision and it is not possible to declare anything about Nearctic Atomaria . Further, A. schmidli resembles to palaearctic species, e.g. A. abietina J. R. SAHLBERG, 1888, A. bella REITTER, 1875 ( fig. 4 ) or A. elongatula ERICHSON, 1846 ( fig. 5 ) .
