Gonçalves, Clayton Corrêa & Marques-Costa, Ana Paula, 2014, Two new species of Tetralidia Marques-Costa & Cavichioli (Hemiptera: Cicadellidae: Neocoelidiinae) from Peru with a key to species of the genus, Zootaxa 3815 (2), pp. 279-285 : 280-282

Tetralidia pachamama sp. nov.

( Figs 1–11 , 23–24 )

Diagnosis. Subgenital plates, in ventral view ( Fig. 6 ), slightly narrowed towards apex; connective ( Fig. 8 ) Vshaped; aedeagus ( Figs 10–11 ) with simple shaft, without processes, spines or lamellae, apex curved ventrally; anal tube ( Fig. 5 ) with long basiventral processes turned posteriorly, areolate-sculptured at apical third.

Measurements (mm). Male holotype: total length 7.1; crown median length 0.75; transocular width 1.37; interocular width 0.81; pronotum median length 0.66; width between humeri 1.62; mesonotum median length 1.0; mesonotum maximum width 1.2; forewing length 5.7; forewing maximum width 1.55.

General color. Body ( Figs 23–24 ) with ground color pale yellow. Crown ( Figs 1 , 23 ) with two pairs of orange maculae, maculae of anterior pair subtriangular close to anterior margin, and the other at basal half, subquadrangular, adjacent to compound eyes. Frons ( Fig. 2 ) without maculae. Pronotum ( Figs 1, 3 , 23–24 ) with five orange stripes, only median stripe complete. Forewings ( Figs 4 , 23–24 ) yellowish and hyaline, without maculae. Legs yellow ( Fig. 24 ), with concolorous setae.

External morphology. External morphological characters as in generic description ( Marques-Costa & Cavichioli, 2008), except: forewing ( Figs 4 , 23–24 ) about 3.7 times longer than maximum width; venation weakly visible, except apically.

Male terminalia. Pygofer ( Fig. 5 ), in lateral view, weakly produced; lobe higher than long; posterior margin slightly concave; apex rounded with few microsetae. Subgenital plates, in ventral view ( Fig. 6 ), with basal twothirds fused; enlarged at base and gradually narrowed towards apex; lateral margins with slight concavity between basal third and middle third, and between middle third and apical third; ventral surface with three pairs of preapical setae; apices rounded; in lateral view ( Fig 7 ), approximately as long as pygofer; slightly curved dorsally; dorsal margin with numerous setae on middle third. Connective ( Fig. 8 ) V-shaped; approximately half length of styles. Styles ( Figs 8–9 ) without preapical lobe; apex sclerotized and truncated, moderately curved ventrally; with setae on ventral preapical portion. Aedeagus ( Figs 10–11 ) long and narrow, simple, without processes, spines or lamellae; shaft slightly sinuous, apex curved ventrally, slightly bilobed; preapical gonopore. Anal tube ( Fig. 5 ) membranous; with pair of elongated basiventral processes turned posteriorly, areolate-sculptured at apical third.

Female unknown.

Etymology. The new species name alludes to the fertility goddess of Inca mythology.

Material examined. Male holotype: PERU, Cusco, Sierra de Santa\ Rosa, 23 rd km E Makuzo\ 12°58’03”S 70°19’56”W \ 450m, 21.viii.2012, light\ A.P.M. Santos & D.M. Takiya” ( MUSM). Male Paratype: same data as holotype, ( DZRJ).

Notes. Tetralidia pachamama sp. nov. resembles Tetralidia viracocha sp. nov. in having the pygofer lobe higher than long; aedeagus with shaft longer than the preatrium, with apex curved ventrally; and anal tube with basiventral processes strongly directed posteriorly. However, it can be easily distinguished from this and other species of the genus by the simple aedeagus, without processes, spines or lamellae.
