http://lsid.speciesfile.org/urn:lsid: Orthoptera.speciesfile.org:TaxonName:475233

Diagnosis. Moderately robust appearance. Anterior and posterior edge of pronotal disk with three acute spines, mesozone with two spines. Male with cylindrical cerci and a small distal spine, subgenital plate rectangular with a “U” shaped notch. Female ovipositor moderately broad, without serrulations in the valves and progressively shortening from the mesial portion.

Holotype. 1 male — Colombia, Nariño, Barbacoas, Reserva Natural Río Ñambi, 1335 m,. 1°17’44’’ N – 78°4’45’’ W. 1 October 2012. M Salazar. (CAUD).

Paratypes. 3 males and 1 female (PSO-CZ). One of the males deposited at CAUD.

Description. Male. Body general coloration greenish brown with numerous light green, greenish yellow and black spots and stripes (Fig. 17 F). Ovoid head in front view (Fig. 17 C); reddish brown eyes; black rostrum with a light green stripe from the bottom margin of the antennal fossa to the fronto-clypeal suture; thinner “Y” shaped light yellow stripe above the previously described one. Genae brown with yellow bottom edge, scapus of the antennae with a black stripe in the frontal margin. Fastigium of the vertex narrow, slightly divided at the apex in dorsal view. Pronotum (Figs. 17 A,B) with lateral rectangular lobes and straight edges, pronotal disc armed with spines arranged as follows: anterior edge with a central spine and two lateral of similar size; mesozone with one spine on each side, with similar size as those on the anterior edge; posterior edge with three spines, one in each side and one in the center (smaller than those in the sides). Meso and metasternum rectangular, wider than long, with the infero-lateral edges moderately elevated; metafurcal ridge elongated and with two deep excavations, one in each side. Legs: all the genicular processes armed with acute spines; inferior margin of the femora with five spines; dorsal margin of the tibiae with three pairs of tubercles, the first pair lays on the tympanum inferior margin, and the remaining two pairs, of smaller size, lay on the mesial portion of the tibiae; mid-femora with five spines in the ventro-external margin; mid-tibiae with six ventral spines in both internal and external margin. Hind-femora with 11 ventro-external spines; hind-tibiae with 10 dorso-external and 11 dorso-internal spines. Sub-lanceolate tegmina with light green and yellow veins, stridulatory crest straight and as long as three quarters of the width of the pronotal disc posterior margin; membranous area of the stridulatory crest between MP and CUP veins. Tenth tergite moderately convex in the medial portion, forming a small straight notch (Fig. 17 D). Epiproctus longer than wider and with rounded apex; cylindrical cerci with a small spine at the latero-apical margin. Subgenital plate rectangular, slightly longer than wider, with a “U” shaped notch. Styli cylindrical and as long as two thirds of the length of the subgenital plate, gradually tapering from base to apex (Fig. 17 E).

Female. Of similar size and coloration than the male (Figs. 18 A,B,C,F). Tenth tergite straight, without visible modification; epiproctus as long as wide. Cerci conical, tapering from base to apex, and as long as a third of the length of the ovipositor (Fig. 18 D). Subgenital plate triangular, as long as wide and gently truncated distally (Fig. 18 E). Ovipositor solid and robust, as long as a third of the posterior femur and curving upward gradually from the mesial portion of its length; valvae moderately wide without serrations.

Etymology. This new species is named after its type-locality Ñambí River Natural Reserve.

Comments. this new species differs from all other species of the genus by its robust aspect and the shape of the ovipositor. The authors agree with Gorochov (2012) in that the subgeneric organization of the genus Championica is unclear; therefore, this new species is not placed in any of the existing subgenera. Currently, a brief review of the Championica is been conducted, where the status of the species is been revised and a delimitation of the subgenera will be provided (Cadena-Castañeda & García, in prep.).
