Wing membrane hyaline; forewing apex not falcate; forewing with Sc ending at the level of the first fork of Rs; male epandrium without mesial elongated expansions, and apical internal margin with a lobe bearing black spines.</p><p>Redescription. Head (Fig. 1b): mostly pale, except for the dark brown gena, apical half of labrum and ocellar triangle; set with pale pubescence, particularly in the vertex; three ocelli, lateral ocelli slightly larger.Antennae long, filiform, pale, with pale pubescence; flagellum generally slightly darker than scape and pedicel. Male maxillary palpi dark brown and broad, and set with elongated black setae.</p><p>Thorax (Fig. 1a–b): covered with yellowish pubescence. Pronotum brown with the medial area pale. Antepronotum and postpronotum with one long black seta on each lateral margin. Mesonotum and metanotum brown laterally and pale medially; with two long black setae on the anterior half of each segment. Scutella pale, with two long black setae on posterior margin. Pleural region pale.</p><p>Legs (Fig. 1a): coxae pale; yellowish pubescence slightly longer than on other segments. Trochanter brown. Fore and mid leg with femur and tibia brown, except for the tip of the tibia dark brown, tarsi dark brown. Hind leg with darker brown tibia and tarsi; in general, more robust than anterior legs, but with tarsi shorter, particularly the first and second tarsomeres, which are nearly half the size of their respective counterparts in the fore and mid legs. Legs set with sparse short black setae; tibial spurs long and with the basal half dark brown and the apical half pale; tarsomere V prehensile.</p><p>Wings (Fig. 1f): narrow with apex rounded. Membrane hyaline, but pterostigma and area near it brown; thyridium present; longitudinal veins brown, covered by short black setae. Forewing costal crossvein varying from zero to two; humeral crossvein present; Sc at the level of Rs first fork; Rs fork not forming a right angle; Rs 1+2 forking before the pterostigma end; Rs 3+4 forking half way through to the level of Sc end and pterostigma; two pterostigmal crossveins; M origin much before to Rs origin; M and Rs first forks at the same level; Cu 1 ending at the level of Rs 3+4 fork; A 1 ending after to Rs origin. One crossvein between Rs 1 and Rs 2, three between Rs 1+2 and Rs 3, two between Rs 3 and Rs 4, three between Rs 4 and M, one between Rs 4 and M 1+2, two between M 1 and M 2, two between M 2 and M 3, one between M 1+2 and M 3+4, one between M 3 and M 4, one between M 4 and Cu 1, one between Cu 1 and Cu 2. Hindwing similar to forewing but shorter.</p><p>Abdomen (Fig. 1a): shorter than wings, mostly brown, but apical margins of the tergites dark brown, pleura pale. Segments covered by pale pubescence.</p><p>Male terminalia (Fig. 1c–e): epandrium brown, set with pale setae; in dorsal view, internal margin diverging apically, posterior margin rounded, apical internal margin with an internal lobe set with short thick black setae; in lateral view, slightly shorter than basystilus, dorsal margin mostly straight; posterior margin obliquely truncate and posterodorsal corner rounded. In posterior view bean shaped, with internal margin set with short thick black setae. Cercus about as long as sternite IX, brown, set with pale setae. Basistylus set with long yellowish setae, particularly at the posterior margin, brown with apex pale. Dististylus short, slightly darker than basistylus, with apex rounded, set with long yellowish setae. Penisfilum broad at base, abruptly narrowed medially, tapering towards the apex, curving backwards at the medial region, basal broad region darker than remaining areas.</p><p>Female terminalia: with cercus short, brown, set with yellowish setae. Subanal plate and tergite XI brown and set with short yellowish setae. Cercus, subanal plate, and tergite XI ending about at the same level. Gonocoxosternite dark brown, set with yellowish setae, not fused ventrally; in lateral view with a subapical membranous concavity.</p><p>Material examined: Uruguay: Artigas, Laureles stream, 25.xi.1959, coll.
