  Revision of the Elusive Harvestmen Genus Discocyrtulus Roewer, 1927 (Opiliones: Laniatores: Gonyleptidae): Investigating the Presumed Northeastern Brazilian Discocyrtus-Like Relatives ABSTRACT A maximum parsimony analysis based on morphological characters (23 taxa; 98 characters; 1951 scorings) was conducted to test the monophyly of Discocyrtulus Roewer, 1927, and to assess its phylogenetic relationships within Gonyleptidae. The results recover the species currently assigned to Discocyrtulus as phylogenetically distant from Pachylinae sensu stricto and nested instead within Discocyrtus sensu stricto +, forming a clade together with Discocyrtus moraesianus Mello-Leitão, 1923. Accordingly, Discocyrtulus is removed from Pachylinae Sørensen, 1884, and left without subfamilial assignment. As a result, Discocyrtulus now comprises Discocyrtulus crenulatus (Roewer, 1913) comb. nov. , Discocyrtulus marginalis Roewer, 1929, and Discocyrtulus moraesianus (Mello-Leitão, 1923) comb. ...

Leiurus fezzanensis sp. n. from Fezzan Province, Libya (Scorpiones: Buthidae)

ABSTRACT

Leiurus fezzanensis sp. n. is described from the Fezzan Province, Libya. Detailed illustrations and a map showing the distributions of all Leiurus species in Africa are given. Leiurus fezzanensis differs from granulations of carapace, trichobothrial pattern on fixed finger, granulation of fifth segment of metasoma and pectinal tooth count. Since L. libycus Birula, 1908 was recently excluded from the scorpion fauna of Libya,L. fezzanensis is currently the only Leiurus species known from the country.
