Hypopygium small; surstylus subtriangular, tapered and bearing 1 apical and 1 subapical strong seta; postgonite enlarged and covered by small setae. Description. Similar to A. angustifacies stat. rev., except as noted. Male. Body length: 2.1–2.4 mm. Wing: 2.0– 2.2 mm long, 0.7–0.8 mm wide. Antenna. Postpedicel longer than arista-like stylus; FAr ratio, 1.19. Thorax. About 6 ac and 5 dc pairs of setae. Wing. CuAx: 0.44; RMx: 1.7. Lower calypter pale yellow with fan of about 6 brownish setae. Leg I. 35, 37, 18, 14, 9, 5, 4. T rusty yellow due to brownish infuscation. Leg II. 33, 35, 19, 8, 6, 4, 3. T rusty yellow, with 1 ad seta at basal 1/3 and 4 setae apically (1 ad, 1 pd, 1 av and 1 pv). Leg III. 37, 42, 19, 9, 6, 4, 3. T brownish infuscated at basal 1/4, and apical 1/5, bearing 4 pd bristles along basal 3/5, and 2 ad setae between mid-length and apex, apex with 4 setae (1 av, 1 pv, 1 ad and 1 pd); tarsus simple. Hypopygium. As in Fig. 16A–D, similar to A. angustifacies stat. rev. Female. Similar to males, except by MSSC and as noted. Body length: 2.0– 2.7 mm. Wing: 1.9–2.4 mm long, 0.7–1.0 mm wide. Terminalia. As in generic description (similar to Fig. 24). Distribution. Brazil, Bolivia and Trinidad and Tobago (Fig. 26). Etymology. Same etymology as A. balin sp. nov., but Gimli was the honored Dwarf, and is from the book The Lord of the Rings (by J. R. R. Tolkien). This name should be treated as a noun in apposition.

The new species runs to “ A. femoralis ” using Parent (1933) key and is based on Becker’s (1922) description of that species (see Remarks under A. femoralis). Achradocera gimli sp. nov. has a wide and disjunct geographic distribution (Fig. 26) and major variations are listed below. Bolivian specimens have entirely yellow FII (dorsally infuscated in type series); Northern Brazilian specimens (Roraima state) specimens appear to be smaller in size (in comparison with type series); and the Tobago specimens have a slightly different proportion between head and thorax (also in comparison with the type series). However, we believe that those characteristics are insufficient to reliably differentiate new species, because specimen preparation methods can modify coloration, while the life histories of those exemplars can change some subtle aspects, as well as body size. Thus, to be more conservative, we considered specimens from these regions as conspecific until further analyses may point to a different conclusion.
