description: Dorisiana viridis (Olivier)
Body color brownish, curved in lateral view, covered with sparse bristles, mainly in the ventral region (Fig 1c).
Head. In dorsal view, crown including eyes, about four times wider than long, slightly wider than the anterior margin of pronotum (Fig 1d). In ventral view, rostrum reaching posterior coxae.
Thorax. In dorsal view, pronotum and mesonotum with similar length, metanotum length very short in comparison with the pronotum and mesonotum (Fig 1d). Wing cases developed, reaching abdominal segments (Fig 1c). In the foreleg, femur with long and sharp posterior tooth, slightly bent forward, length approximately three times longer than the width of its base; small and sharp accessory tooth and an intermediate tooth present; femoral comb usually with six teeth, the anterior tooth bigger and projected forward (femoral formula 2-1-6) (Fig 2c). Tibia arched, flattened laterally; apical tooth long; blade of the tibia with a distinct tooth; tip of the blade of the tibia developed and separated from the apical tooth by a strong incision (Fig 2c). Tarsi developed, folded over the inner surface of the tibia, two segmented, the apical tarsomere much longer and fitted with a pair of claws of unequal sizes. In the mid leg, tibia with two, sometimes three, short spines on its length. When two, distance between these spines similar to the distance between the distal spine to the tibia apex (Fig 5a). In the hind leg, tibia with four apical spines, and in some cases there is a very small spine internally (Fig 4b). Tarsi two segmented, the apical tarsomere much longer and fitted with a pair of claws of unequal sizes.
Abdomen. Size varying according to the development of the nymph, sometimes reduced, with the distal extremity of hind wing almost reaching the apex of abdomen, or elongated, with the distal extremity of hind wing reaching the middle of the abdomen. Female: 8th and 9th sternites with two sharp protrusions in posterior margins. Male: 10th sternite with two strong projections forming an open angle at the anterior margin (Fig 3c).

Material studied. BRAZIL. Paraná: Rolândia, ii – 2003 (D. H. B. Maccagnan), 3 ♂ and 13 ♀.
Comment. A femoral comb with seven teeth occurred in 12.5% of the studied specimens.
