Carineta fasciculata (Germar)

Body brown, narrow and elongated, abdomen with bristles scattered mainly in the ventral region ( Fig 1i ).

Head. In dorsal view, crown including eyes, about three times wider than long. About the same width as the anterior margin of pronotum ( Fig 1j ). In ventral view, rostrum reaching posterior coxae.

Thorax. In dorsal view, pro and mesonotum similar in length, metanotum reduced in length ( Fig 1j ). Wing cases developed, reaching abdominal segments ( Fig 1i ). In the foreleg, femur with long and sharp posterior tooth, slightly curved, its length of about one and a half times the width of its base; small, a robust and not sharp accessory tooth and an intermediary tooth present; femoral comb usually with five or six teeth (femoral formula 2-1-5 or 2-1-6) ( Fig 2f ). Tibia arched, flattened laterally; apical tooth relatively robust, the blade of tibia without any tooth, tip of the blade of tibia under-developed and separated from apical tooth by a light incision ( Fig 2f ). Tarsi developed, folded over the inner surface of the tibia, two segmented, being the apical one much longer and provided with a pair of claws of unequal sizes. In hind legs, apex of tibia with four spines, the external stronger than the remaining ( Fig 4e ).

Abdomen. Size varies according to the development of the nymph, may be reduced, with the distal extremity of hind wing almost reaching the apex of abdomen, or elongated, with the distal extremity of hind wing reaching middle of abdomen. Female: 8th and 9th sternites with two sharp protrusions in the posterior margin. Male: posterior margin 9th sternite with two protrusions and 10th sternite with strong ventral projection ( Fig 3f ).
