Kempnyia kaingang sp. n.

( Figs. 8-15 )

Material examined. Holotype ♂, BRAZIL, Santa Catarina, Nova Teutônia , 27°18’ 52°23’, 300-500 m, Jan. 1956, F. Plaumann, K. klugii . Paratype, ♀, same data as holotype ( BMNH) .

Adult habitus. General color light brownochraceous. Head light brown to yellowish, darker at lappets, in part around M-line and from the anterior ocellus to the postfrontal line and paired ocelli ( Fig. 8 ). Pronotum light brown with yellowish mid stripe. Legs, wings and cerci light brown-ochraceous.

Male. Forewing length 13 mm. Subgenital plate short, less than half its width, bases turned inwards ( Fig. 9 ). Hammer oval, broader posteriorly. Basiconic sensilla of tergum 10 long ( Fig. 11 ). Paraprocts with a large subapical tooth and minute apical sensilla ( Fig. 10 ). In the penial armature ( Figs. 13-15 ), the foramen is large, the posterior rim is high and bent backwards, the anterior tips of the longitudinal bars are loose. The hooks are large and curved medially, crossing under the gonopore tube. The inner part of the curve presents thin-walled crenulations.

Female. Forewing length 18 mm. Subgenital plate light in color, apical contour rounded, apically a minute indentation Sternum 9 with the darker extensions extending anteromesially ( Fig. 12 ).

Remarks. The above two specimens were identified as K. klugii (Pictet) , a dark species with completely different penial armature ( Zwick, 1972). In fact, K. kaingang is most similar to K. tenebrosa , with its large hooks that cross under the gonopore tube (cf Figs. 5- 6) or rises at its side (Zwick, l.c.), but in K. kaingang the dorsal rim of the armature projects posteriorly more strongly, the hooks are stronger and the gonopore tube is thick. In addition, Kempnyia tenebrosa , as the name implies, is a dark species, in contrast to the light-colored K. kaingang .

Etymology. The name honours the Kaingang native people of Brazil, of the Macro-Ge language group, that still lives in indigenous areas in Santa Catarina and in nearby states. Name in apposition.
