sp. nov

Amazobenna pennyi   sp. nov

( Figs. 19–27 View FIGURES 19–23 View FIGURES 24–27 , 29 View FIGURES 28–29 , 30)

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

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 View FIGURES 19–23 ). Forewing yellowish, semihyaline with brown oval spot in apical portion of clavus extending to first cubital cell ( Fig. 29 View FIGURES 28–29 ); 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 View FIGURES 24–27 ).

Head: median carina of frons weakly marked ( Fig. 20 View FIGURES 19–23 ); pedicellus as long as wide ( Fig. 21 View FIGURES 19–23 ). 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 View FIGURES 19–23 ). Legs: hindtibia with 7 apical spines; hindtarsus with 8+8 apical spines.

Male genitalia ( Figs. 24–27 View FIGURES 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.
