Prando, Jádila Santos, Gonçalves, Clayton Corrêa & Takiya, Daniela Maeda, 2017, On the wasp-mimicking sharpshooter genus Propetes Walker, 1851 (Hemiptera: Cicadellidae: Cicadellinae): description of a new species, proposal of a new synonymy, and distributional notes, Zootaxa 4281 (1), pp. 165-175 : 167-168

Propetes sakakibara sp. nov.

( Figs 1–4 , 9–15 )

Length (mm). Males 13.0 – 15.0.

Diagnosis. Connective anterior margin straight, without median lobe ( Fig. 11 ). Aedeagus symmetrical; shaft shorter than atrial process; pair of atrial processes, each trifurcate, with two dorsal rami subequal in length with apices distant from each other for, at most, length of one ramus, and ventral ramus with length approximately one third of whole process length ( Figs 12–13 ).

External morphology. External morphological characters as in generic description ( Young 1968: 204‒205).

Color (holotype). Dark-brown. Crown, in dorsal view, with two small pale yellow maculae near posterior margin ( Fig. 1 ). Face, in ventral view, dark-brown with two pale yellow maculae on dorsal portion of frons. Pronotum, in lateral view, reddish-brown ( Fig. 2 ). Mesonotum dark-brown; scutellum with yellow apex. Forewing hyaline brown with dark-brown veins ( Fig. 1 ). Legs dark-brown on dorsal surface and reddish-brown on lateral surface; hind tibia reddish-brown on basal half and pale yellow in part of apical half, apex black.

Male genitalia. Pygofer moderately produced posteriorly; in lateral view, subrectangular; with transverse slightly membranous line dividing basal third from apical two-thirds; microsetae distributed on apical two-thirds; ventral margin with short basal rounded process; posterior margin obliquely truncate ( Fig. 9 ). Subgenital plate, in lateral view, extending to approximately midlength of pygofer, in ventral view, subtriangular; ventral surface and external lateral margin with microsetae ( Figs 9‒10 ). Connective, in dorsal view, approximately triangular; anterior margin straight, without median lobe; dorsal keel present ( Fig. 11 ). Style extending slightly posterior to connective apex; apex truncate ( Fig. 11 ). Aedeagus symmetrical; preatrium well developed; shaft, in lateral view, sigmoid, shorter than atrial processes, in caudoventral view, laterally compressed and with preapical region expanded; pair of atrial processes, each trifurcate, with two dorsal rami robust and subequal in length with apices distant from each other for, at most, length of one ramus, and ventral ramus slender and long with approximately one-third of whole process length ( Figs 12‒15 ).

Female. Unknown.

Variation found in paratypes. Color. Crown brown with anterior half yellow and median longitudinal stripe pale yellow. Pronotum, in dorsal view, dark-brown with two small pale yellow maculae near anterior margin ( Fig. 3 ). Thorax, in lateral view, with three distinct pale yellow maculae ( Fig. 4 ). Male genitalia. Aedeagus with dorsal rami of atrial process, in lateral view, not subequal in length, and with apices close together ( Figs 14‒15 ).

Etymology. This species is named in honor of Dr. Albino M. Sakakibara (retired, Universidade Federal do Paraná) in recognition of his numerous contributions to Auchenorrhyncha taxonomy. The species epithet is treated as a noun in apposition.

Notes. Propetes sakakibara sp. nov. resembles P. triquetra as follows: (1) crown and pronotum dark-brown or with few yellow maculae ( Figs 1, 3 ); (2) aedeagus with shaft shorter than atrial processes ( Figs 13, 15 ); and (3) aedeagal atrial processes, each trifurcate ( Figs 13, 15 ). However, the new species differs from P. triquetra mainly by the shape of the connective and aedeagal atrial processes. In P. sakakibara sp. nov. the atrial process ventral ramus is long, measuring approximately one-third of whole process length and apices of dorsal rami are distant from each other for at most the length of one ramus ( Figs 12, 14 ) and the connective does not have a median anterior lobe ( Fig. 11 ). In P. triquetra the atrial processes ventral ramus is very small, measuring approximately one-tenth of whole process length and dorsal rami apices are distant from each other for a distance longer than the length of one ramus ( Fig. 17‒18 ) and the connective has a median anterior lobe ( Fig. 16 ).
