2C4D8672FF8DFFACD6C844A08FE98DA3.taxon	discussion	Remarks. Stark (2001) and Stark & Zúñiga (2003) both show details of the internal male genitalia for this species. The current specimen has a modified hammer like that of the holotype and the epiproct tip is subtly notched, slightly more so than is shown for the holotype (Stark & Zúñiga 2003). Three female specimens collected with the Napo male are too small to represent this species and lack distinctive characters which would permit their identification beyond genus level. 3 4 5	en	Stark, Bill P.

2C4D8672FF8CFFACD47446398E288EEE.taxon	discussion	Remarks. Although the labels for the holotype and the new specimen indicate separate provinces are involved, apparently both specimens were collected from the Rio Palenque Biological Station.	en	Stark, Bill P.

2C4D8672FF8CFFAFD6C146B789DC8DDC.taxon	materials_examined	Material examined. Holotype ♂ from Argentina, Salta, 15 km W Chicoana, Canyado Gotera, February 1992, S. A. Marshall (UGIC). Adult habitus. General color brown patterned with yellow. Head and pronotum damaged, partially obscuring pattern; head with dark quadrangular area over ocelli extending forward to M-line; M-line represented by pale oval area; pale brown pigment extends forward of M-line and darker pigment occurs on lappets (Fig. 1). Pronotum apparently almost uniformly brown. Wing membrane pale brown, veins amber except R-vein dark brown. Legs brown with narrow, black, apical femoral band. Male. Forewing length 8 mm. Hammer a short, wide thimble shaped structure with basal diameter greater than height (Fig. 2). Aedeagal apex a simple scoopshaped structure with truncate tip and low V-shaped dorsal keel (Figs. 3 - 5). Hooks chelate, ventral membranous lobes well developed. Female. Unknown. Larva. Unknown.	en	Stark, Bill P. (2007): Anacroneuria Marshalli (Plecoptera: Perlidae), A New Stonefly From Argentina, And Two New Records From Ecuador.

2C4D8672FF8CFFAFD6C146B789DC8DDC.taxon	etymology	Etymology. The patronym honors Stephen Marshall, collector of the holotype.	en	Stark, Bill P. (2007): Anacroneuria Marshalli (Plecoptera: Perlidae), A New Stonefly From Argentina, And Two New Records From Ecuador. Illiesia 3 (17): 171-173, DOI: http://doi.org/10.5281/zenodo.4754733
2C4D8672FF8CFFAFD6C146B789DC8DDC.taxon	diagnosis	Diagnosis. Anacroneuria marshalli appears to be part of a complex of Andean species including A. montera Stark & Sivec, A. canchi Stark & Sivec, and A. pastaza Stark (Stark & Sivec 1998; Stark 2001). The former species has a distinctive large dark area covering the posterior half of the head, and the aedeagal apex is turned sharply ventrad beyond the hooks, whereas the latter species is generally similar to A. marshalli in pigment pattern but lacks chelate hooks, has a broader aedeagal apex and the hammer is much “ taller ” than in the new species. Although A. canchi has chelate hooks, it also has a much shorter aedeagal tip which barely projects beyond the hooks, and the apex is also angled sharply ventrad. This species also has a narrow, inclined plane type of hammer rather than the short thimble shape found in A. marshalli.	en	Stark, Bill P.
