Anchieta eurydella ( Westwood, 1867) View in CoL

( Figs. 2 View FIGURE 2 a‒i, 16a, 25, Map 1)

Mantispa (Trichoscelia) eurydella Westwood, 1867: 501 View in CoL . Holotype: female, “Amazonia” (probably Brazil), unspecified locality, D. Bates, 1861 (OUM), images studied.

Anchieta eurydella View in CoL ; Penny 1982b: 419 (redesc.); Penny & da Costa 1983: 614 (redesc.); Ohl 2004: 146 (cat.).

Since the data available for the species of Anchieta View in CoL is insufficient, this species is here redescribed in order to provide complementary information and illustrations to the descriptions of Penny (1982b) and Penny & da Costa (1983).

Specimens examined. Colombia: Meta: Cabaña Carrillo, NNP Sierra de la Macarena, 3°21’N – 73°56’W, 460 m, 29.X.2003, W. Villalva, Malaise trap m‒4240 (1 ♀‒IAvH).

Diagnosis. Anchieta eurydella is distinguished from other congeneric species by having forewing membrane hyaline, amber to light yellow with an orange or light brown band near to the wingbase at the level of sc-r crossvein and a spot of the same color between C and R1, near to the pterostigma. The hindtibia is swollen, dark brown at posterior margin, remainder including a basal fifth and the apex orange.

Redescription. Description based on one pinned female.

Head. Mandibles orange, apically changing to amber, maxillary and labial palpi orange. Clypeus and labrum yellow, frons yellow, with two semicircular brown spots beneath antennae ( Fig. 2 View FIGURE 2 c). Vertex and occiput mostly dark brown, with two pale yellow stripes originating from frons to near of coronal suture, where are abruptly widened ( Fig. 2 View FIGURE 2 d). Scape and pedicel ochre, flagellum with 43 articles, 39 are brown and four preapical pale yellow, all covered with brown setae.

Thorax. Prothorax as long as pterothorax; anterior margin of pronotum dark brown, orange in the prozona, posterior half dark brown ( Fig. 2 View FIGURE 2 d), entire surface densely covered with long and thick setae. Meso- and metathorax with notal sclerites brown in the middle, ochre or orange at periphery, all covered with thick and long orange setae ( Fig. 2 View FIGURE 2 d). Pteropleura with anterior sclerites ochre in the middle, brown at periphery, posterior sclerites mostly brown, all covered with long and yellow setae ( Fig. 2 View FIGURE 2 b).

Legs. Forecoxa posteroventrally dark brown pigmented, remainder ochre or orange. Outer trochanter surface with apical process; dorsally brown, remainder orange ( Figs. 2 View FIGURE 2 f, g). Femur with a dark brown dorsal spot extending beyond of the middle of the inner surface, ventral- and basally yellow, orange or light brown at apex; outer surface with three dark brown spots near to the row of minor spines, the first elongated, located on the distal half, the second transversely oriented and fused with the dorsal spot, the third is small and located basally. Sub-basal spine yellow with tip brown. Entire surface of femur covered in thick layer of brown or bright yellow setae. Basal half of tibia yellow, distal half brown. First tarsomere amber at apex and ventral surface, basally orange, other tarsomeres yellow. Midleg with all segments orange. Hindleg with coxa ochre; trochanter and femur orange; tibia distinctly widened, three times as long as wide, flattened, slightly larger than the forefemur, dark brown along the posterior margin, remainder surface including the tip orange in color ( Fig. 2 View FIGURE 2 h, i). Tarsomeres short, with thickened brown or orange setae.

Wings. Forewing length, 9 mm; apex rounded; venation alternating bright orange and yellow, densely covered with orange setae; membrane hyaline, amber to light yellow with an orange band near the wing-base at the sc-r crossvein level ( Fig. 2 View FIGURE 2 a). Distal region between costal, subcostal and radial fields, with a bright orange spot. Base of R1 yellow. Pterostigma subrectangular consisting of five crossveins, proximal half light brown or bright orange, light orange at distal half ( Figs. 2 View FIGURE 2 a, 16a). Costal field with 8‒11 crossveins; subcostal area with only one crossvein near to its mid-length. 2‒4 veins arising from 1RA cell, always at distal half; three from 2RA cell; Rs with three or four gradate crossveins. Hindwing length 5.3 mm; venation bright orange, covered with abundant pilosity, membrane hyaline; CuA bordering with orange on membrane, from base to its second fork. Pterostigma elongated, elliptical, well sclerotized, bright orange. Costal field orange, with five or six crossveins. Two veins arising from 1RA cell and one or two from 2RA ( Fig. 2 View FIGURE 2 a).

Abdomen. Tergites I‒VII ochre, with abundant pale yellow setae, tergite IX brown; sternites light yellow. Female gonocoxites ochre, arched, as long as the last five abdominal segments ( Fig. 2 View FIGURE 2 e).

Remarks. The type specimen of Mantispa (Trichoscelia) eurydella varies in the color pattern of the body and wings. The variation includes the following: forewing very light brown infuscated in the r-cu crossvein, a transverse band near to the mid-length of wing and in the 1r-rs; proximal half of pterostigma brown ( Fig. 16 View FIGURE 16 a). The number of veins arising from the Rs and the size is also different between the material examined and the type specimen, although these are characteristics that varies frequently. This species is recorded in Colombia for the first time.

Distribution. Brazil, Colombia.
