Type material.— ARGENTINA. HOLOTYPE: male ( INHS), “ Misiones / Dto. Apóstoles / Azara. 5 Jan. 1988 / Heath-Sanborn-/ Noriega Coll.” . PARATYPES: seven male and two female same data as holotype (five male and one female MSHC, three male and one female AFSC); one male ( MSHC) “ Misiones / Dto. Capital / Posadas. 6 Jan. 1988 / Heath-Sanborn-Noriega / Coll. EX: Sycamore; one male and one female ( AFSC) “ BOLIVIA: Departmento de Santa Cruz / Provincia Cordillera, Charagua / 19 o 47’ 24.65”S 63 o 11’ 48.25”W / Altitude 790m, 30-XI-2001 / G. Navarro coll.”

Etymology. The species is named in honor of our long time colleague in Argentine cicada research, Fernando G. Noriega.

Diagnosis. —The unique genitalia of the male quickly distinguish the species as new. The lack of infuscations on the forewings and/or abdominal markings that form an arch-like pattern distinguishes this species from D. toulgoueti Boulard & Martinelli, 2011 , D. panamensis (Davis, 1939) and D. crassa Boulard, 1998 , D. christinae Boulard & Martinelli, 2011 , D. viridifemur ( Walker, 1850) , and D. beniensis Boulard & Martinelli, 2011 . The mesothoracic markings of the new species are absent in D. bicolor ( Olivier, 1790) and D. glauca ( Goding, 1925) . The new species lacks the black anterior margin of the mesothorax, ground color scutal depression, and partially hyaline basal cell of the forewing in D. sutori Sueur, 2000 ; the black only around the ocelli on the head and a black marking along the wing groove of D. amoena (Distant, 1899) ; and the black submedial and lateral sigillae of D. drewseni ( Stål, 1854) and D. bogotana (Distant, 1899) .

The remaining species found in Argentina are more similar in general appearance. The new species can be distinguished from D. semilata ( Walker, 1850) by the lack of marking on the lateral and submedian sigillae and along the anterior of the mesothorax, the sinuate posterior margin of the male operculum, the lack of black pile producing a striped appearance on the abdominal tergites, and the horn-like appearance of the genitalia of the new species. The new species can be distinguished from D. metcalfi Sanborn & Heath nom. nov. pro D. viridis ( Olivier, 1790) by the distinct spots on the posterior head and posterior to the eye, the marks along the parapsidal suture, the timbal cover with straight ventral margin, the sinuate posterior opercular margin, the lack of black pile on the abdominal tergites, the two lateral, horn-like extensions of the uncus, the basal pygofer lobe is short, abdominal segment 9 of the female is marked with fuscous, the dorsal beak extends beyond the anal styles, and the ovipositor extends slightly beyond the dorsal beak in the new species.

Description

Coloration.—Ground color of head and thorax green marked with piceous; abdomen tawny. Coloration fades to brownish ochraceous with time.

Antennal segments piceous except tawny annulus on distal scape.

Thorax.—Pronotum brownish ochraceous with transverse piceous line behind brownish ochraceous anterior margin, narrowed medially, expanding into anterior portion of paramedian and lateral fissures and expanding laterally onto anterior quarter of disc between lateral and ambient fissures and onto medial portion of pronotal collar lateral margin. Tawny mark in lateral and central paramedian fissures, mark extends to ambient fissure in some paratypes. Transverse mark in ambient fissure across midline. Pronotal collar brownish ochraceous. White pile in paramedian, lateral and ambient fissures in some paratypes. Mesonotum brownish ochraceous with piceous anterior submedian sigilla, mark continues along parapsidal suture before expanding to cover posterior submedian sigilla, remaining submedian sigilla greenish tawny. Lateral sigilla piceous anteriorly, remaining portion greenish tawny. Scutal depression piceous. Marking reduced in some paratypes. Piceous spot on anterior wing groove. Long white pile laterally and between anterior arms of cruciform elevation, pile very thick to absent in paratypes. White pile at anterior paramedian fissure and black pile between anterior arms of cruciform elevation, shorter pile along anterior margin and parapsidal sutures in some paratypes. Metanotum brownish ochraceous, Ventral thoracic plates brownish ochraceous except piceous medial basisternum 2 and lateral spot on basisternum 3. Venter covered with white pruinosity and white pile.

Forewing and hind wing.—Hyaline. Forewing venation green at base becoming fuscous past node except tawny anal vein 2 + 3, green faded to tawny in some paratypes, small piceous spot at base of cubitus posterior + anal vein 1. Basal cell semitransparent tawny. Infuscation in proximal clavus. Basal membrane gray and orange. Hind wing venation similarly colored to forewing except for tawny median vein and cubitus posterior.

Notes. — Dorisiana noriegai sp. n. is from the understory vegetation in the Paranense floristic province in Argentina ( Sanborn et al., 2011a) and the xeric deciduous pre-Andean Chaco forest in the transition to subhumid Bolivian-Tucuman Yungas in Bolivia (G. Navarro, in litt. 16-II-2012).
