Sequencing of the CO1 mitochondrial gene (barcoding) highlighted a possible different species in the semi-desert region of Mexico. After a detailed morphological analysis we describe Scapholeberis duranguensis n. sp. (Cladocera: Anomopoda: Daphniidae). Specimens from the type locality, El Chupadero, Durango, were compared with specimens of S. armata armata Herrick, 1882 and S. armata freyi Dumont and Pensaert, 1983 from Canada and southeastern, central and northern Mexico. The main characters that differentiate the new species are: (1) a thicker denticulate membrane with a conspicuous underlying hyaline membrane at the posterior rim of the valves, (2) fewer setae in the gnathobase of trunk limb II and (3) longer and more rectilinear ejector hooks in trunk limb I. The presence of a pore-like structure at the top of the head was also observed, however we are not certain whether this can be considered as a distinctive character, as it was not consistent in all SEM scanned organisms. The denticulate membrane, the number of setae in the gnathobase of trunk limb II and the length of the ejector hooks are characters shared with other species, however, the combination of them and in particular the structure and thickness of the double membrane at the posterior rim of the valves lead us to conclude that S. duranguensis is a species different from S. armata and from other members of this genus. The CO1 sequences of S. armata freyi and S. duranguensis n. sp. showed a mean divergence of 12.02%, thus supporting the morphological differences between them. Finally, a comparison of the CO1 sequences of Scapholeberis duranguensis n.sp. with other Scapholeberinae available in GenBank supported our results.

Three New Species

Six saxicolous species of Buellia, which were previously generally identified as Buellia punctata (Hoffm.) A. Massal., were examined from the Sonoran Desert. None of the species belongs to Beullia punctata s. str. Though inconspicuous, it can be demonstrated that the thallus morphology of these species is quite distinct and far less variable than previously assumed. Most species are epilithic, even though their thalli also show some degree of substrate penetration. Buellia sequax (Nyl.) Zahlbr., not previously reported from North America, is exclusively chasmolithic. Three new species with epilithic thalli, Beullia christophii Bungartz sp. nov., Beullia ryanii Bungartz sp. nov., and Beullia tergua Bungartz sp. nov., are described. Two species with filiform conidia are not treated in the genus Amandinea. We discuss why the current delimitation of this genus, based solely on conidial shape, is rejected: Buellia pullata Tuck., with filiform conidia, is consequently not transferred into Amandinea. Amandinea lecideina (H. Mayrhofer & Poelt) Scheid. & H. Mayrhofer is synonymized with Beullia prospersa (Nyl.) Riddle.Key words: North America, taxonomy, Physciaceae, Amandinea, conidia, thallus morphology, new species.
