Gymnocnemia boliviana Banks 1920: 330 .

Type locality. Rio Longo, Bolivia.

Taxonomy: Banks 1943: 168 (in Navasoleon).

Holotype female. Length of body 18 mm., forewing length 26 mm., width 6.0 mm., hindwing length 26 mm., width 5.0 mm.; wing span 54 mm. Coloration: Face (Fig. 2) nearly all pale brown; broad brown transverse dark brown band above antennae, not reaching eye but produced ventrally between antennal sockets; mouthparts pale brown; palpi nearly all pale brown; antennal scape and pedicel mostly pale brown, flagellum missing; vertex all pale brown except for prominent sublateral dark brown round area near middle; pronotum (Fig. 11) nearly all light brown with irregular dark brown areas mostly lateral; pterothorax mostly pale brown with complex dark brown areas mostly paired along middle and lateral margin; mesoscutellum pale brown with prominent lateral dark brown area anteriorly; metascutellum nearly all pale brown with much reduced dark brown areas; forewing with small dark brown rhegmal mark (Fig. 39); vertex with anterior row of dark brown markings missing; midfemoral sense hair short and dark brown; thoracic pleura (Fig. 20) mostly pale brown with scattered dark brown areas, ventrally mostly dark brown; legs pale brown with dark brown spots at setal bases on foretibia, midfemur, midtibia; abdominal tergites mostly dark brown with irregular pale brown areas; Chaetotaxy: Clypeus with long pale setae; pronotum with many long setae, as long as, or longer than the longest setae on the clypeus; forefemoral sense hair about equal to that midfemur and about 2 times as long as femoral diameter; ventral setae on distal tarsomere of foreleg longer than middle diameter of tarsomere, hooked apically; ventral setae on other legs also long but not hooked apically. Structure: Distal palpomere of labius slender; pronotum about as long as wide (Fig. 11); foreleg basitarsus as long as tarsomeres 2–4, about 2.5 times longer than distal tarsomere which is slightly bent preapically; hindleg basitarsus about as long as tarsomeres 2–4, about 2 times longer than distal tarsomere; forewing (Fig. 39) costal cells wider than high basally, higher than wide starting about level of radial sector, with 7 presectoral crossveins; forewing radial sector originates well distad of cubital fork; posterior fork of CuP+1A reaches hind margin about at level of radial sector; female terminalia (Fig. 54) with posterior gonapophysis about 3.5 times as long as diameter with all setae shorter than gonapophyseal diameter); lateral gonapophyses transverse, partially fused, with numerous small scraping setae about equal to those on ventral area of ectoproct; pregenital plate small, about 4 times wider than long, with small central tooth; spermathecal (Fig. 54) serpentine in shape with posterior part strongly bent at about 180 o angle.

Distribution. Bolivia.

Collection times. December to January.

Material studied. Holotype female and 1 paratype male.

BOLIVIA. Yungas: Chulumani, 1700 m, 18.XII.1955 (1m, FSCA); I.1948. (1f, FSCA). Rio Longo, H. Fassl (1f, MCZC) .

Discussion. This Bolivian species can be recognized by coloration. The vertex markings with anterior area pale brown, without dark brown area below antennae; anterior half of prothorax all pale; mesoscutellum and metascutellum with median dark brown streaks.

Miller and Stange (1985) published a description of larvae that, at the time, were identified as N. bolivianus . However, all of those specimens have now been identified as the new species N. lithophilus .
