Amazobenna pennyi, Viegas & Ale-Rocha, 2019

Viegas, Eduarda Fernanda Gomes & Ale-Rocha, Rosaly, 2019, A review of the Neotropical genus Amazobenna Penny, 1980 with description of a new species and description of the male of Amazobenna reticulata Penny, 1980 (Hemiptera: Fulgoromorpha: Cixiidae), Zootaxa 4577 (3), pp. 561-570 : 567

Amazobenna pennyi sp. nov

( Figs. 19–27 , 29 , 30)

Type material. Holotype male ( DZUP). BRASIL, Amazonas , Santa Isabel do Rio Negro , Rio Padauari, igarape do Maia, 00.194410N– 064.01083W, CDC, 08–10.vi.2010, R. & R.S. Hutchings cols.

Condition of the holotype: Glued on paper triangle; right and left flagellum lost. Right foreleg broken and stored in a microtube; foretibia and foretarsus lost; right midtarsus lost; third tarsal segment of the right hindleg lost. Right forewing mounted between coverslips. Genitalia not dissected.

Measurements. Holotype male: Body length: 4.2 mm (7.4 mm including wings); forewing length: 6.15 mm.

Diagnosis. Amazobenna pennyi sp. nov. can be promptly distinguished from A. reticulata by the general color of the wing and body. In addition, the genitalia are quite distinct, having the characteristic slender anal segment with triangular apex in posterior view, and genital style widening distally with truncated apex, whereas in A. pennyi sp. nov. the anal segment is broad with a trapezoidal apex in posterior view, and the genital style is narrow distally, widened in the basal 2/3, with round apex.

Description. Coloration. General body color yellow ( Figs. 19–23 ). Forewing yellowish, semihyaline with brown oval spot in apical portion of clavus extending to first cubital cell ( Fig. 29 ); long, narrow, brown, transverse band extending from the vein M5 to apex of pterostigma; narrow brown stripes covering base of medial, cubital and anal veins; narrow brown stripes covering radial and median veins at apex of wing; anterior cubital vein covered by brown stripe and small pale-brown spot at apex of CuA2. Pterostigma whitish-yellow. Hindwing yellowish, semihyaline. Genital style pale-brown ( Figs. 24–25 ).

Head: median carina of frons weakly marked ( Fig. 20 ); pedicellus as long as wide ( Fig. 21 ). Thorax: pronotum somewhat emarginated; median and lateral longitudinal carinae of mesonotum weakly marked, median carina not reaching posterior margin of mesonotum, lateral carinae not reaching anterior margin of mesonotum ( Fig. 22 ). Legs: hindtibia with 7 apical spines; hindtarsus with 8+8 apical spines.

Male genitalia ( Figs. 24–27 ): anal segment elongate and wide, only slightly longer than wide in dorsal view, dorsal margin almost straight, ventral margin abruptly produced ventrally at apex in lateral view, apex trapezoidal in posterior view. Pygofer with lateral lobe well produced, apex round in lateral view, parallel in ventral view. Medioventral process of pygofer conical in lateral view, with posterior margin triangular in ventral view. Genital style narrowed distally, widening in the basal 2/3 on outer margin, inner margin almost straight, parallel in ventral aspect, with apex round, divergent in posterior view. Aedeagus with straight shaft bearing long spines.

Etymology. The species is named to honor Dr. Norman D. Penny, who created this genus, for his immense contribution to the knowledge of invertebrate fauna in the Amazon.

Distribution. Brazil (Amazonas) (Fig. 30).

Discussion. Previously, the type species A. reticulata was the only known species included into the genus. Since A. pennyi sp. nov. fits very well to the generic description, we consider both species congeneric. The discovery of a further species for this genus allowed us to verify that the diagnostic characters used by Penny (1980) to describe it remain valid.
