Name
Nuurcala obesa Wang & Ren sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Differential diagnosis
Differs from Nuurcala popovi and Nuurcala srneci in having relatively small head, and antennal sockets conspicuous at sides, antennae long and thick; forewing with dark colouration except for R area, a dark maculae present at the edge of Sc area; hindwing with dark colouration; Legs with dark colouration, femora thick, tarsus with five segments and a claw (Fig. 1).
Description
Holotype (Fig. 1): body medium to large size, length about 23.8 mm as preserved, total estimated length is 25.2 mm, and width 9.9 mm; Abdomen with 6–7 visible segments. head small, length 1.8 mm, and width 2.5 mm, antennal sockets conspicuous at sides. Pronotum, shield-like, vaulted, transversal, simple symmetrical zonal colouration at the margin, length 6.2 mm, width 6.9 mm. Forewings: length 22 mm, width 6 mm; one dark maculae present at the edge of Sc area, dark colouration with pale area in R; 55 veins at margin; intercalaries thick, all over wing surface; Sc 3 branches, shorter than clavus; R sigmoidal 15 branches, with undifferentiated Rs, reaching the anterior wing margin; M slightly curved with 9 branches, most posterior branches of M reaching wing apex; CuA slightly curved to posterior wing margin and 10 branches; CuP curved and simple; clavus long, more than a third of the wing’s length; A with tertiary branches. Hind wing (17 mm long as preserved vs. 22 mm long for forewing) with branched Sc; both R1 and RS about 9 veins; M 4 branches; Cu (±9) with additional blind branches that may reticulate, fan-like pleating present visible on forewing. Legs with dark colouration, femora thick, about 2 times as long as tibia, tarsus with five segments and a claw, spines obscure.
Paratypes (Figs 2–4): only forewing preserved, length range about 11.5–19 mm, width range about 5.2–5.7 mm; 42–48 veins at margin; Sc 3-5 branches, R sigmoidal 12–15 branches, M slightly curved and 4–9 branches, CuA 7–10 branches.
Materials
