Gonçalves, Clayton Corrêa & Takiya, Daniela Maeda, 2024, Dutrapona, a new genus and three new species of Gyponini (Insecta: Hemiptera: Cicadellidae) from Central and South America, Zootaxa 5497 (1), pp. 100-110 : 102-104

Dutrapona reticulata sp. nov.

( Figs 1 –2, 7–19)

Diagnosis. Forewing (Fig. 10) with venation reticulated at apical half. Male pygofer (Fig. 13) with several long hair-like setae grouped on ventral half of median third; pair of caudoventral processes (Fig. 14) lobed. Subgenital plate (Figs 13, 15) slender, subtriangular; ventral surface covered by long hair-like setae. Style (Fig. 17) with blade broad, slightly broader at middle third and abruptly narrowed at apical portion. Aedeagus (Figs 18, 19) with basilateral processes extending slightly beyond shaft apex, curved anterodorsally, with apex acute; shaft slightly sinuous, curved anterodorsally, apex bifid.

Total length. 18.0 mm (n = 1 male).

Coloration. Yellow ( Figs 1 –2). Head ( Figs 7 –9) with eyes and ocelli red; antennal ledges black.

Description. Head, in ventral view (Fig. 8), clypeus with lateral margins slightly convergent apically. Forewing (Fig. 10) with venation reticulated at apical half; apex acutely rounded. Other characteristics as in generic description.

Male terminalia. Sternite VIII, in ventral view (Fig. 11), approximately 1.4 times longer than wide; posterior margin rounded, notched medially. Valve, in ventral view (Fig. 12), approximately 1.8 times wider than long; posterior margin rounded. Pygofer, in lateral view (Fig. 13), subtriangular; lateral lobe with several long hair-like setae grouped on ventral half of median third; caudoventral margin rounded; apex rounded; in posterior view (Fig. 14), caudoventral processes lobed. Subgenital plate (Figs 13, 15) subtriangular, broad at base and narrowing towards the apex; approximately 5.8 times longer than maximum width; inner lateral margin straight, outer lateral margin slightly rounded; long hair-like setae along outer lateral margin and throughout apical half; apex acutely rounded. Connective (Fig. 16) with anterior margin broadly excavated; stem slightly longer than arm length; arms broad. Style (Fig. 16), approximately twice the length of connective; in lateral view (Fig. 17), blade broad, slightly broader at middle third and abruptly narrowing at apical portion. Aedeagus (Figs 18, 19) with basilateral slender processes, arising from atrium, extending slightly beyond shaft apex, curved anterodorsally, apex acute; shaft slightly sinuous, curved anterodorsally, apex bifid and acutely rounded.

Female. Unknown.

Etymology. The species name refers to the reticulate venation of forewings (Fig. 10).

Material examined. Holotype: ♂, “ ECUADOR, Napo, Yanayacu \ Biol. St. 5 km SW Cosanga \ 0°35.967’S – 77°53.419’W \ 2100 msnm; 29.ix.2009; Hg-\ vapor light; Geert Goemans ” ( MEPN).

Notes. Dutrapona reticulata sp. nov. is easily distinguished from other species of the genus by the forewing with reticulated venation (Fig. 10), while D. tenuis sp. nov. and D. zahniseri sp. nov. do not have reticulate venation (Figs 23, 36). Furthermore, D. reticulata sp. nov. occurs in South America ( Ecuador), while D. tenuis sp. nov. and D. zahniseri sp. nov. are recorded from Central America, Costa Rica, and Panama respectively.
