Resumo

A new species of Hanshumba Young, 1977 is described and illustrated from the Mantiqueira mountain range (southeastern Brazil), municipalities of Wenceslau Braz (state of Minas Gerais) and São Bento do Sapucaí (state of São Paulo). The new taxon is associated with olive orchards and is considered a potential vector of the bacterium Xylella fastidiosa. This bacterium causes a serious disease known in Brazil as olive leaf desiccation syndrome. Hanshumba mariae sp. nov. can be distinguished from the other five known species of the genus by the following combination of features: (1) apical third of ventral margin of male pygofer with small inner process bearing setae; (2) male abdominal segment X (anal tube) without processes; (3) style with apex narrow, obtuse, not foot-shaped; (4) aedeagus with distinct dorsal lobe along basal two-thirds and with apical portion expanded, bearing dorsal projection; (5) paraphyses with distal pair of rami forceps-like, their basal halves divergent from each other, distal halves approximately parallel, apices acute; (6) female sternite VII with posterior margin shallowly emarginate, bearing slight median lobe; and (7) valvula II of ovipositor with approximately 15 low teeth. Both males and females of the new species are described in detail. A key to the six known species of the genus is provided.
