Anacroneuria terere View in CoL sp. n.

( Figs. 7–12 View FIGURES 7 – 9 View FIGURES 10 – 12 )

Description. General colour yellowish-brown. Area between ocelli light brown, expanding anteriorly into a T-shaped bar, rest of head lighter ( Fig. 7 View FIGURES 7 – 9 ). Clypeal area light brown laterally and frons lighter. Antennae light brown, palpi yellowish. Pronotum square shaped, anterior corners angular, posterior corners rounded, light brown with yellowish median stripe and light, lateral areas, rugosities darker. Legs light brown, tibiae and tarsi darker. Wings yellowish hyaline, veins light, region between C and R veins opaque.

Male. Forewing length, 11.2 mm. Penial armature ( Figs. 10–12 View FIGURES 10 – 12 ) narrowing slowly to end piece. Hooks basally with a distinct hump, rest smoothly curved with pointed tips. In lateral view, dorsal keel absent, oblong penial apex bends dorsally. Distal ventral vesicles absent.

Female. Forewing length, 14.6–15.5 mm, n=16. Subgenital plate four-lobed ( Fig. 8 View FIGURES 7 – 9 ), lateral notches shallow, median one distinctly deeper. St9 with distal margin sinuous and sclerotized, field of hairs V–shaped, longer hairs near margin. Egg oval ( Fig. 9 View FIGURES 7 – 9 ) and dark brown, 0.37 x 0.20 mm; egg batch cord shaped.

Remarks. The penial armature is similar to that of A. saltensis ( Froehlich, 2002) , but the dorsal keel is absent in A. terere . The apical portion of the penial armature is similar to that of A. caraja Froehlich, 2002 , but in this species the shoulders are not conspicuous. In addition, A. terere differs from both species in color pattern; A. caraja is a pale, whitish color whereas A. saltensis is yellowish.

Etymology. Tereré , from the Guarani language, is a typical cold beverage, made with “erva-mate” ( Ilex paraguariensis ) and widely consumed in Argentina, Brazil, Uruguay and Paraguay. First invented by the Guaraní natives who lived in Paraguay and western Brazil (Mato Grosso do Sul), tereré was spread by the dwellers of that region, and for centuries has been a social beverage. It is a noun in apposition.
