Meng, Rui, Gnezdilov, Vladimir M. & Wang, Yinglun, 2015, Two new species of the genus Peltonotellus Puton (Hemiptera: Fulgoromorpha: Caliscelidae) from northwestern China with a world checklist, Zootaxa 4052 (4), pp. 465-477 : 467-470

Peltonotellus brevis , sp. nov.

Diagnosis. This species resembles Peltonotellus raniformis ( Mulsant & Rey, 1855) in female ( Holzinger 2007, Figs 14 , 19 , 20 , 27 , 28), but differs from the latter by the following: 1) vertex, pronotum and mesonotum testaceous with a wide white stripe medially, in P. raniformis , vertex, pronotum and mesonotum fulvous without white middle stripe; 2) fore wings pale gray brown, in P. raniformis , fore wings with white stripe; 3) frons with two inconspicuous fuscous specks on two side of median carina, in P. raniformis , frons with two obvious large black circular specks at middle. In male, the phallobase with dorsal margin concave near distal 1/3, the ventral process of phallus short, not reaching the base of phallobase; in P. ranif or mis, phallobase with dorsal margin straight, the ventral process of phallus long, surpassing the base of phallobase.

Description. Male length (N=7) (including tegmen): 1.7–1.9 mm, length of tegmen: 0.7–0.9 mm; female length (N=12) (including tegmen): 2.8–3.0 mm, length of tegmen: 1.0–1.2 mm.

Coloration: Male. Vertex, pronotum and mesonotum yellowish with a wide white stripe medially, aurantiaceous on its both sides. Vertex with a pair of annular speckles laterally. Eyes gray. Frons off-white between two sublateral carinae, fulvous between lateral margin and sublateral carina, with pale sensory pits. Clypeus yellowish-white with black stripes on both sides of anteclypeous. Gena yellowish-white with black speckle near antennae. Fore wings fuscous-piceous in distal part near costal margin, fulvous in proximal part near posterior margin, and with a wide white stripe from humeral angle to anal angle. Legs fulvous with bits of black maculae. Abdomen piceous, with sensory pits fulvous, with white speckles on both sides of black middle line, with relatively small white speckles laterally, fuscous fascia forming between the white speckles on each side ( Figs 1–3 ).

Female. Vertex, pronotum and mesonotum pale fulvous with a wide white stripe medially, fulvous on its both sides. Eye gray. Frons pale yellow with two inconspicuous dark marks between two sublateral carinae, fuscous between lateral margin and sublateral carina, with pale sensory pits, median carina off-white. Clypeus fulvous with large black macula at middle and black stripes on both sides of anteclypeous. Fore wings greyish brown. Legs fulvous with black spots. Abdomen black at middle line, with off-white and fawn and black fasciae, sensory pits off-white ( Figs 4–6 ).

Vertex trapezoidal, 2.7 times wider than long in middle line, disc moderately impressed, with two rounded depressions on lateral area, anterior margin straight, posterior margin angulately emarginated ( Figs 1, 4 ). Frons with upper margin almost straight, lateral margin slightly elevated; with three carinae, sublateral carina semicircle; with three rows, 24–28 sensory pits in male and about 20 in female between lateral margin and sublateral carina on frons, frons 1.1 times in male and 0.9 times in female longer than wide at widest part below eyes ( Figs 2, 4 ). Frontoclypeal suture bending upwards ( Figs 2, 4 ). Clypeus triangular with median carina on postclypeus, with two depressions near frontoclypeal suture ( Figs 2, 4 ). Pronotum large, anterior margin surpassing half of eyes, and slightly convex at middle, posterior margin roundly concave, 1.6 times longer than vertex in middle line, with median carina; about 25 sensory pits on each side, lateral lobe with two rows and six sensory pits ( Figs 1, 4 ). Mesonotum 1.6 times longer than pronotum in middle line, with three carinae, with 12 sensory pits on each side ( Figs 1, 4 ). Fore wings nearly quadrangular, 1.4 times longer than wide at widest part ( Figs 1, 4 ). Hind wing absent. Hind tibia with one large lateral spine. Spinal formula of hind leg 6–2–2.

Male genitalia: Anal tube short in dorsal view, lateral margins subparallel, apical margin obtusely rounded; distal part slightly recurved in lateral view ( Fig. 8 ). Anus located at basal half of anal tube, paraproct dumpy ( Fig. 8 ). Phallobase asymmetrical in dorsal view, bilobate near apical part, the right side wider than left one, in lateral view, dorsal margin concave near distal 1/3, ventral margin convex near middle ( Figs 9–11 ). Phallus small, only reaching to the middle of phallobase, with a short thin process directing to base on right side ( Figs 9, 11 ). Genital styles in lateral view narrow at base, widest portion at basal one fourth, gradually slender to apex ( Fig. 7 ). Pygofer with posterior margin morderately sinuate, slightly convex at middle, then concave, anterior margin concave at middle ( Fig. 7 ).

Female genitalia: Anal tube nearly ovate in dorsal view, apical margin arcuately convex ( Fig. 12 ). Anus located at basal half of anal tube, paraproct dumpy ( Fig. 12 ). Gonoplacs nearly quadrangular, disc moderately flat, apical margin obtusely rounded, with a shallow notch near middle of dorsal margin ( Fig. 15 ). Gonapophyses IX fused at base, with about ten spinal teeth along dorsal margin of posterior connective lamina ( Figs 13, 14 ). Anterior connective lamina of gonapophysis VIII narrow, with 3 large teeth at apex ( Fig. 16 ). Gonocoxae VIII nearly square ( Fig. 16 ). Sternum VII with middle of posterior margin almost straight ( Fig. 17 ).

Bursa copulatrix membranous, basal half elongate tubular, the apical half pouched ( Fig. 18 ). Anterior vagina elongate, posterior vagina relatively short. Oviductus communis stout. Spermatheca well-developed with five parts: orificium receptaculi, ductus receptaculi, diverticulum ductus, spermathecal pump and glandula apicalis. Orificium receptaculi correspondingly robust and short; ductus receptaculi thin and elongate; diverticulum ductus orbiculate, followed by spermathecal pump slender and tubular; two thick glandula apicalis at apex of spermathecal pump ( Fig. 19 ).

Material examined. Holotype: male, Luo Mountain, Tongxin County, Ningxia Hui Autonomous Region, China, 22 August 2011, coll. Silong Xu. Paratype: 6 males, 12 females, same data as holotype.

Etymology. The specific epithet is derived from Latin word “ brevis ”, referring to the aedeagus with short fine process on the right side.
