Mejdalania unciformis   sp. nov.

Figs 19−28 View FIGURES 19–28 , 33−34 View FIGURES 29–34

Diagnosis. Pygofer, in lateral view ( Fig. 21 View FIGURES 19–28 ), subquadrangular, ventral margin with apical lobe, lateroapical process with dorsal rami long and strongly curved dorsally, exceeding half height of caudal margin; subgenital plates, in ventral view ( Fig. 23 View FIGURES 19–28 ), subtriangular, with lateral margins converging towards the apex in the basal two-thirds; aedeagus ( Figs 27–28 View FIGURES 19–28 ) with apodemal processes shorter than the shaft, slender for the entire length, shaft slender and sinuous, S-shaped.

Measurements (mm). Male holotype: total length 7. Paratype (male), 5.9−6.6 (n=2).

Coloration. Body yellow ( Figs 33–34 View FIGURES 29–34 ), green in life. Face, pronotum and mesonotum ( Figs 19 View FIGURES 19–28 , 33 View FIGURES 29–34 ) yellow. Forewing ( Fig. 20 View FIGURES 19–28 ) yellow semi-hyaline with a dark yellow longitudinal strip adjacent to the anal margin. Legs ( Fig. 34 View FIGURES 29–34 ) yellow.

External morphology. External morphological characters as in the generic description.

Male terminalia. Pygofer, in lateral view ( Fig. 21 View FIGURES 19–28 ), subquadrangular, approximately as long as high; anterior margin with strongly developed lobe; ventrobasal and dorsoapical margins thickened, ventral margin rectilinear with a apical lobe, dorsal margin strongly declivous apically; lateroapical process with dorsal rami long and strongly curved dorsally, exceeding half the caudal margin, apex acute, ventral rami acute and directed ventrally, short, about one-tenth the length of the dorsal rami; apex truncated. Subgenital plates, in lateral view ( Fig. 23 View FIGURES 19–28 ) with apical third slightly curved dorsally; in ventral view ( Fig. 24 View FIGURES 19–28 ), subtriangular, with lateral margins converging towards the apex in the basal two-thirds. Connective ( Fig. 25 View FIGURES 19–28 ) approximately half length of the style. Style ( Figs 25–26 View FIGURES 19–28 ) with rectilinear. Aedeagus ( Figs 27–28 View FIGURES 19–28 ) with apodemal processes shorter than the shaft, sinuous and slender, apex acutely rounded; shaft sinuous, S-shaped, flattened dorsoventrally, slender for the entire length with smooth lateral margins.

Female terminalia. Female unknown.

Material examined. Holotype ♂: “ Sinop , Mato Grosso \ Brasil, x.1975 \ M. Alvarenga leg” ( DZUP)   . Paratypes: 2 ♂ same data as holotype, ( DZRJ, DZUP)   .

Etymology. The species name alludes to hook shape of the lateroapical process of pygofer ( Figs 21–22 View FIGURES 19–28 ).

Remarks. Mejdalania unciformis   sp. nov. resembles M. bia   sp. nov. by the subquadrangular shape of the pygofer and by the subtriangular shape of the subgenital plates and resembles M. longa   sp. nov. by the shape of the aedeagus. However, M. unciformis   sp. nov. is easily distinguished from other species by the long lateroapical process of the pygofer, curved dorsally ( Figs 21–22 View FIGURES 19–28 ).
