The new micro-dolichopodid genus Haromyia gen. nov. and the type species H. iviei sp. nov. are described from the island of Dominica in the Lesser Antilles. Males and females of Haromyia are distinguished by the large setae on a bulging clypeus, minute size, and wing veins that are nearly straight and evenly diverging from wing base. Haromyia does not fit readily into any contemporary dolichopo...

Including more than 6500 species, Opiliones is the third most diverse order of Arachnida, after the megadiverse Acari and Araneae. This database is part 2 of 12 of a project containing an intended worldwide checklist of species and subspecies of Opiliones, and it includes the members of the suborder Laniatores, infraorder Grassatores of the superfamilies Samooidea and Zalmoxoidea plus the gener...

Genera Stenichnus and Scydmoraphes are distributed in the Northern Hemisphere, with a few rather peculiar species described from South America. Type series of Stenichnus andicola Franz, Scydmoraphes venezolanus Franz and Scydmoraphes peruanus Franz were examined and the first of these species is transferred to Sciacharis Broun, while two new generic names are established to accommodate the two ...

Microproblematica are microfossils whose suprageneric taxonomic status is unknown. Many microproblematica display an encrusting way of life and can therefore be included in the group of “micro-encrusters” that during the Upper Jurassic were conspicuous components of microbial carbonate crusts (e.g. LEINFELDER et al., 1993; SCHMID, 1996; DUPRAZ & STRASSER, 1999, 2002). These forms are widespread...

The bitunicate ascomycete genus Johansonia is presently treated as a member of Saccardiaceae, a family regarded as incertae sedis within the Ascomycota. Recent collections on leaves of a leguminous host, Dimorphandramollis, in Mato Grosso, Brazil, led to the discovery of a new species of Johansonia, described here as J.chapadiensis. Based on DNA sequence data of the nuclear ribosomal DNA (LSU),...

Analysis of three northern hemisphere Boreal-Arctic species of Pseudopallene has shown that those species are morphologically distinguishable from their congeners in Australian waters. The holotypes of Australian species Pseudopallene laevis, Pseudopallene ambigua and Pseudopallene harrisi are compared with each other and with additional material from southern Australia. Sixteen species of Pseu...

Specimens collected during the ANDEEP I and II expeditions revealed three new species belonging to the family Anarthruridae and family incertae sedis. One new species of Anarthruridae, Ithyomus antarcticus n. sp. is described. Also described are two new species belonging to genera currently not assigned to a family; one in the genus Parafilitanais (P. denticulus n. sp.) and one in Pseudoarthrur...

The genus Cheilopallene is reviewed. Three species are assigned to species incertae sedis pending further analysis. Specimens from Lizard Island, Queensland, previously identified as C. nodulosa are reassigned to C. brevichela. Suspected sexual dimorphism represented by the presence of a chelifore scape node in female C. nodulosa is supported by the finding of the same dimorphism in C. breviche...
