Mejdalania longa View in CoL sp. nov.

Figs 10−18 View FIGURES 10–18 , 31−32 View FIGURES 29–34

Diagnosis. Pygofer, in lateral view ( Fig. 12 View FIGURES 10–18 ), subtriangular lateroapical process with dorsal rami robust and acute, directed caudally, ventral rami shorter and directed anteroventrally; subgenital plates, in ventral view ( Fig. 14 View FIGURES 10–18 ), subrectangular, with lateral margins almost parallel; aedeagus ( Figs 17–18 View FIGURES 10–18 ) with apodemal processes longer than the shaft, slender for the entire length, shaft slender and strongly sinuous, S-shaped.

Measurements (mm). Male holotype: total length 6.1. Paratype (male), 5.7−6.1 (n=3).

Coloration. Body yellow ( Figs 31–32 View FIGURES 29–34 ), green in life. Face ( Fig. 10 View FIGURES 10–18 ) with frons mostly orange, dorsal margin yellow. Pronotum ( Fig. 31 View FIGURES 29–34 ) yellow with three longitudinal light orange stripes, one median and two lateral. Mesonotum ( Fig. 31 View FIGURES 29–34 ) yellow, with orange basal angles. Forewing ( Fig. 11 View FIGURES 10–18 ) yellow semi-hyaline with a dark yellow longitudinal strip adjacent to the anal margin. Legs ( Fig. 32 View FIGURES 29–34 ) yellow.

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

Male terminalia. Pygofer, in lateral view ( Fig. 12 View FIGURES 10–18 ), subtriangular, high in the basal half and narrowing in the apical half, approximately 1.7 times longer than high; anterior margin with well-developed lobe; ventrobasal and dorsoapical margins thickened, ventral margin rectilinear, dorsal margin strongly declivous apically; lateroapical process with dorsal rami robust and acute, directed caudally, shorter ventral rami directed anteroventrally; apex rounded; apex rounded. Subgenital plates, in lateral view ( Fig. 13 View FIGURES 10–18 ) with apical third slightly curved dorsally; in ventral view ( Fig. 14 View FIGURES 10–18 ), subretangular, with lateral margins almost parallel. Connective ( Fig. 15 View FIGURES 10–18 ) approximately half length of the style. Style ( Figs 15–16 View FIGURES 10–18 ) with apophysis slightly curved dorsally. Aedeagus ( Figs 17–18 View FIGURES 10–18 ) with apodemal processes longer than the shaft, sinuous and slender for the entire length, apex rounded; shaft strongly sinuous, S-shaped, flattened dorsoventrally, slender for the entire length with smooth lateral margins.

Female terminalia. Female unknown.

Material examined. Holotype ♂: “ Brasil, AM [Amazonas], Manaus \ ZF2, Km 14, Torre \ 2°35’21”S – 60°06’55”W \ 12-15.ix.2004, lençol c/ luz\ mista e BLB, 35m de altura” “ J.A. Rafael, C.S. Motta, F.F.\ Xavier F°, A. Silva F° & S.\ Trovisco leg.” ( INPA) GoogleMaps . Paratypes: 2 ♂ same data as holotype, ( INPA) GoogleMaps ; 1 ♂ same data as holotype, except “ 10-13.xii.2004; C.S. Motta, A.S. Filho S. Trovisco & M. Curtin leg.” ( DZRJ) GoogleMaps .

Etymology. The species name alludes to the long apodemal processes of aedeagus, exceeding the length of the shaft ( Fig. 17 View FIGURES 10–18 ).

Remarks. Mejdalania longa sp. nov. resembles M. unciformis sp. nov. in the shape of the aedeagus. However, the subtriangular shape of the pygofer ( Fig. 12 View FIGURES 10–18 ) and the long apodemal processes of aedeagus, exceeding the apex of the shaft ( Figs 17–18 View FIGURES 10–18 ) are characteristics that easily differentiate M. longa sp. nov. from other species of the genus.
