Diagnosis of nymph. Body dark brown. Frons and labrum dark brown, parietalia mostly yellowish, brown at epicranial line. Pronotum brown, lighter laterally. Mesonotum and metanotum brown with Mesonotum and metanotum with whitish muscle insertions.

Description of nymph. Female: Body length 8.0–11.0 mm (not including the cerci, n= 50), general color dark brown, body bright and robust. Head: Antennae dark yellow; basally with brown margin; scape larger than rest of antenna. Occiput with V-shaped dark spot, in dorsal view. Frons brown, M-line distinct, light spot lateral of ocellus. Parietalia yellow, brown at coronal line and part of postfrontal line. Eyes black; distance between ocelli 0.3 mm, from ocelli to inner margin of eye, 0.6 mm ( Fig. 2View FIGURES 1 – 6). Mouthparts dark yellow. Labrum brown with small anterodorsal spots lighter in color and anteromedian area dark yellow with fine setae. Maxillae dark yellow, sclerotized outer part of cardo and stipes brownish, margin medial of stipes sclerotized brown; lacinia with two dark brown teeth and a row of seven robust bristles ( Fig. 4View FIGURES 1 – 6). Mandible: dark brown, median region lighter brown; five pointed teeth on distal margin, mostly decreasing in size toward base, but 4 th tooth larger than the 3 rd and 5 th. Two rows of bristles on the ventral margin, first row starting at the base of the 2 nd tooth and other at base of the 4 th tooth ( Figs. 5, 6View FIGURES 1 – 6); labium typical of Perlidae  ( Fig. 3View FIGURES 1 – 6). Thorax: Pronotum dark brown, 1.3 mm long and 2.4 mm wide, without median spots, lateral margins yellow, posterior margin presenting median concavity, median pronotal sulcus and narrow side strip slightly, ventral side dark yellow to dark brown with sulcus well-marked, angle between the anterior arms of Y-line long, small groups of setae on the anterior side of the Y-line ( Figs. 2View FIGURES 1 – 6, 8View FIGURES 7 – 11). Mesonotum and metanotum dark brown, mesonotum 1.1 mm long and 1.7 mm wide, median light area, with brown bands bordered laterally and covered with fine, dark pilosity contrasting with yellowish, hairless areas forming large circles or discs; lateral border of the wing pad lighter in color; metanotum 1.9 mm long and 1.3 mm wide, similar to mesonotum, with spots of various sizes and shapes ( Fig. 7View FIGURES 7 – 11). Gills present on ASC 1, PSC 1 with two branches, AT 2, AT 3, PT 3, A 1 with two branches. Gills absent from ASC, PSC (2, 3) and SL ( Fig. 8View FIGURES 7 – 11). Leg dorsally light yellow to slightly orange, unpigmented ventrally, trochanter with stout dense bristles, base of tibia dark brown, coxa with few bristles; femur with band of dorsal, heavy, transverse bristles apically, bristles absent from posterior surfaces; tibia with band of short, thick bristles anteriorly, a cluster of fine, dense, whitish bristles along entire segment, posteroventral margin with three large, strong spines; tarsus pale brown without strong bristles; ventrally pale with fine bristles ( Figs. 9, 10View FIGURES 7 – 11). Abdomen dorsally dark brown following the general pattern of body, becoming gradually darker in the last four segments; intersegmental membranes dark yellow, visible between anterior and posterior margins of each darker segment; segments with complete dorsal row of bristles that at posterior margin become more distinct from tergum 6 through 10. Ventrally, these bristles extend to a median gap equal to one-quarter of sternum width in the segments 1–7, bristle row complete on sterna of segments 7 and 9 to 10. The eigth sternite presents a median V-shaped notch with margin cleary sclerotized; the sterna were covered by fine, short, sparse bristles, the three last sterna with long bristles distally ( Fig. 11View FIGURES 7 – 11). Cerci dark to light yellow.

Male: Male nymphs differ from female nymphs by: lacking the median shaped-V notch in 8 th sternum; body length 7.0 mm; head 1.5 mm long and 2.0 mm wide; distance between ocelli 0.1 mm, from ocellus to inner margin of eye 0.6 mm. Pronotum light brown, 1.0 mm long and 2.0 mm wide; mesonotum (wing pad I) 1.2 mm long and 2.0 mm wide; metanotum (wing pad II) 1.0 mm long and 1.7 mm wide.

Variation. Females: Body color ranging from light to dark brown; spots often present on pronotum, but variable in size and shape. Often, sterna are darker posteriorly, especially in the last four segments. Long bristles may be present on the lateral margins of terga 6–10 and on the median-lateral margins of sterna 8–10. In some earlier instar nymphs the spots on the posterior portion the head are not evident, nor those on the pro-, meso-, and metanotum. Early instar nymphs often have denser pilosity than that found on penultimate instar nymphs.

Male. Body color varies from light yellow in smaller nymphs to dark brown in later instars; posterior portion of the head are not evident on the pro-, meso-, and metanotum with conspicuous spots, these being less conspicuous in early instars. There are more bristles on smaller nymphs, distributed mainly on the pronotum, mesonotum, and legs.

Distribution. Brazil, Amazonas: Manaus Municipality, Reserva Florestal Adolpho Ducke; Presidente Figueiredo Municipality, Cachoeira da Onça RPPN [private preserve]; Amapá: Macapá municpality, Floresta Nacional do Amapá and Serra Lombardi, limão; Pará: Castanhal Municipality, Apeú River basin; Peixe-Boi Municipality, Peixe-Boi River basin, Altamira municipality, Primavera Municipality, Capanema Municipality. Maranhão: Imperatriz Municipality (adult); Mato Grosso: Chapada dos Guimarães Roraima: Amajari Municipality (adult).

Remarks. The association with the adult was confirmed by rearing. The nymph of this species is similar to A.

manauensis  . It differs by the having a more robust body shape, the head being dark brown, the presence of a median concavity on the pronotum, the sternal sulcus being light brown, the angle of the anterior arms of the Y-line of mesosternum long, and the femur being uniformly light brown. It differs from A. minuta  primarily by the uniformly dark brown body color, the light brown mandibles, light brown femur, and the presence of setae anterior to the arms of the Y-line. In A. manauensis  , the body is usually lighter and less robust in general habitus In A. minuta  , the spot on the head is inconspicuous, whereas in the other species, slightly U-shaped and extending past the ocelli. The distance between the ocelli is 0.2–0.3 mm. In A. marlieri  the spots on the wing pads are large and well defined, whereas in A. minuta  spots are inconspicuous and in A. manauensis  these spots are small and poorly defined.

Anacroneuria marlieri  was the most frequently collected species during this study. We identified additional seven adults with the localities, “Serra do Tepequém (Amajari, Boa Vista, Roraima) deposited in the Museu Integrado de Roraima ( MIRR) that is now part of the Instituto de Amparo Ciência, Tecnologia e Inovação de Roraima ( IACT), two adults with the labels “Serra Lombard, Limão (Amapá), one adult with the label (Imperatriz, Maranhão, igarapé ribeirãozinho), one adult with the label (Mato Grosso, Chapada dos Guimarães, Colégio Agrícola), increasing the known distribution of the species. These records are in addition to nymphs collected in the Floresta Nacional do Amapá and nymphs and adults collected in southern and northeastern Pará.

Ecological notes. Nymphs of A. marlieri  were collected from pristine streams or those with only moderate impacts by agriculture. This species was associated with leaf packs, but often at much more reduced densities in streams influenced by surrounding agricultural areas. Only one large population was found in Papuquara Stream, Castanhal, Pará, where the stream received runoff from cattle grazing or human wastewater.
