Pachyopsis fasciatus sp. nov.

( Figs 23 −44)

Diagnosis. Head ( Figs 23 −25) of male with anterior margin black; pygofer (Fig. 30), with ventral process long, curved distally, almost reaching pygofer apex; aedeagus (Fig. 35) with preatrium constricted near atrium, strongly produced ventrad; shaft apex rounded.

Type locality. São José dos Pinhais, Paraná, Southern Brazil .

Measurements (mm). Length 6.0−6.5 (male), 6.2−7.2 (female).

Coloration. Male: body ( Figs 23 , 24) uniform green or yellowish-green, venter light-yellow. Head (Fig. 25) with anterior margin black, except around ocelli yellow; eye and ocellus red. Pronotum sometimes with light-red dots; posterior margin variable, with broad transverse black band, narrow band or without band.

Female: body ( Figs 36 , 37) uniform green or yellowish-green, without markings, venter light-yellow. Head (Fig. 38) with eye and ocellus red.

Description. Head (Figs 25, 38), in ventral view, frons surface with transverse irregular striae; maxillary plate produced ventrally as far as clypeus apex in male and surpassing slightly the clypeus apex in female. Forewing ( Figs 23 , 24, 36, 37) bright, with veins elevated, with veinlets throughout and extra cross veins near apex. Metatibia PD, AD and AV rows with 15−17, 10−12, 9−11 macrosetae respectively. Abdominal sternite II (Fig. 29) with internal apodemes broad, expanded apically, apex rounded. Other characteristics as in generic description.

Male terminalia. Pygofer (Fig. 30), with posteroventral margin broadly rounded; ventral process long, curved distally, almost reaching pygofer apex. Subgenital plate (Fig. 30) in lateral view, as long as pygofer apex; in ventral view (Fig. 31) 4.7 times longer than wide. Connective (Fig. 32) stem with lateral margins strongly divergent apically; apex emarginated. Style (Fig. 34) with blade straight, no broader apically than near lateral lobe; length from lateral lobe to apex sub equal to length from lateral lobe to base. Aedeagus (Fig. 35) with preatrium constricted near atrium, strongly produced ventrad; shaft apex rounded. Other characteristics as in generic description.

Female terminalia. Sternite VII with posterior margin slightly rounded, with small U-shaped notch at middle. Pygofer (Fig. 39) 1.7 times longer than maximum height; apex subacute. First valvifer (Fig. 40) as high as long; posteroventral angle broadly rounded. First valvula (Fig. 40) slightly higher near base than near apex, ca. 8 times longer than maximum height; dorsal sculpturing starting at mid-length; apical portion (Fig. 41) with ventral sculpture present only near apex, continuous with the dorsal sculpture, apex tapered and acute. Second valvula (Fig. 42) slightly higher apically than basally, ca. 10 times longer than high; apex (Fig. 43) with three rounded teeth. Second valvifer ca. 2.7 times higher than long. Gonoplac (Fig. 44) 5.3 times longer than high; dorsoapical margin long; apex slightly tapered, subacute. Other characteristics as in generic description.

Etymology. The specific epithet refers to the head with a transverse black stripe.

Notes. The new species is similar to P. nigrifacis sp. nov. in having the aedeagus with preatrium strongly produced ventrad, but can be easily distinguished from this species by the preatrium constricted near atrium, and the apex of aedeagus rounded. Pachyopsis fasciatus sp. nov. is the only known species in which the male has the anterior margin of head black.
