Description.

Adult. For a full description of male and female adults of T. cipo see Henriques-Oliveira and Dumas (2015). — Larva. Length up to 15.5 mm (n = 1) (Fig. 26 A). — Head: Coloration (in alcohol) golden to reddish brown with pale brown oval area around stemmata; almost rectangular (Fig. 26 A). Muscle scars pale brown. (Fig. 26 B). Labrum reddish brown, subtrapezoidal with 8 setae (mesal pair shorter than others). Mandibles, asymmetrical, dark, typical for Triplectides . Submentum oval. Ventral apotome subtriangular, wide anteriorly and narrower posteriorly, slightly constricted at mid-length, rounded apically (Fig. 26 B). — Thorax: Pronotum reddish brown with muscle scars pale brown; anterior margin almost smooth, lateral margin smooth and rounded, posterior margin dark (Fig. 26 C, D). Mesonotum with same colors of pronotum, almost covered by a pair of large sclerites: sa 1 each with a single long seta; sa 2 each with 3 setae: (one long mesal and 2 short), sa 3 each with 5 setae (1 long and 4 short); metanotum covered by 5 sclerites: sa 1 quadrate, bearing a single seta, sa 2 seems fused, forming a single sclerite, weakly sclerotized, with a pair of long setae, sa 3 sclerites elongate, oval, each bearing 3 setae of about the same size (Fig. 26 D). Prosternum trapezoidal. Mesosternum with a pair of subtriangular sclerites curved laterally (Fig. 26 E). Metasternum with a dark, sclerotized setal area, bearing about 10 setae (Fig. 26 E). Foretrochantin with distal portion of the anterior margin very curved, pointed, and upturned, with posterior margin almost straight and truncate (Fig. 26 C). Legs pale brown and setose (Fig. 26 G). — Abdomen: Gills simple, present on segments II – VIII; segments II – VIII with dorsal, lateral, and ventral filaments (Fig. 26 H). Segment I with a pair of anteromesal setae; segments III – VIII with lateral fringes. Segment IX dorsal sclerite with 6 long setae on its posterior margin, and 2 pairs of very short setae behind those, 1 anterolateral seta on each side of the sclerite (Fig. 26 E). Anal claw single, large and acute, with a very small dorsal accessory hook (Fig. 26 E). — Larval case: Length up to 25 mm. A simple hollow twig or small sticks (Fig. 26 I). — P upa unknown.

Distribution.

Brazil (Minas Gerais State).

Habitat.

Larvae were collected in areas with characteristic Cerrado vegetation, in stony streams originally formed by quartzite or limestone rock, with many rapids, shallow waters, and very sunny.

Remarks.

In general, larvae of T. cipo are very similar to other Triplectides larvae showing the head and body sclerites golden to reddish brown, with head appearing rectangular. The main characteristics to identify individuals of T. cipo are: submentum oval and ventral apotome subtriangular, widened anteriorly and narrower in posterior portion, with a rounded tip (Fig. 26 B); foretrochantin very curved anterodorsally, pointed and upturned with anteroventral margin rounded (Fig. 26 C), beyond the position of setal area in mesonotum; metanotum composed by 5 sclerites (Fig. 26 D); and abdominal gills present on segments II – VIII with dorsal, lateral, and ventral filaments.
