Wala noda Chamberlin, 1916: 296 , pl. 25, fig. 2 (description & illustration of ♀). Holotype ♀ from PERU: Cuzco: Torontoy , about 2450 m a.s.l., Prof. H.W. Foote leg. 22 July 1911, during the Yale Peruvian Expedition, former collection- or samplenumber 306, MCZ 15880 . Paratype ♀ with the same data as for holotype, except sample-number 307, MCZ 15881, all type material examined .

Corythalia noda — Richman 1989: 295 (Transfer from Wala and Hentzia , following Roewer, to Corythalia ).

Diagnosis. Females distinguished from those of all other Corythalia species by the following characters in combination: anterior margin of epigynal window (W) (AMW) continuous; septum of epigynal windows (SW) not continuous; posterior margin of epigyne (PMoE) reaching beyond epigastric furrow ( Figs 9A , 71D ); secondary spermatheca (SS) slightly longer than broad; connective duct (DST) between SS and primary spermatheca (PS) longer than diameter of PS; copulatory ducts (CD) well recognisable, hardly covered by DST ( Figs 9 B–C, 75G).

Description. Male: unknown.

Female: total length 6.1, carapace length 2.3–2.4, maximal carapace width 1.7, width of eye rectangle 1.3, opisthosoma length 3.1, opisthosoma width 2.1, fovea length 0.23. EYES: AME 0.40, ALE 0.25, PME 0.07, PLE 0.19, AME–AME 0.05, AME–ALE 0.06, PME–PME 1.17, PME–PLE 0.21, ALE–PLE 0.55, PLE–PLE 0.99, clypeus height at AME 0.16, clypeus height at ALE 0.44. Cheliceral furrow with 1 promarginal and 1 retromarginal teeth. SPINATION: palp: no spines. Legs: femur I 1500 (1400{1200}), II 1400 (1500), III 1500 (1500), IV 0400 (0500); patella I–II 1000 (1000), III 1010 (1010), IV 1000 (1010); tibia I 2004 (2004), II 2003 (2004{2003}), III 2033 (1023), IV 1033 (0023); metatarsus I–II 2004, III 3134, IV 3044. MEASUREMENT OF PALP AND LEGS: palp 2.1 [0.8, 0.4, 0.3, 0.6], I 4.0 [1.3, 0.8, 0.8, 0.7, 0.4], II 3.8 [1.3, 0.7, 0.8, 0.6, 0.4], III 4.5 [1.4, 0.8, 0.9, 0.9, 0.5], IV 4.6 [1.5, 0.7, 0.9, 1.0, 0.5]. LEG FORMULA: 4312. COPULATORY ORGAN: epigyne with stout oval W; septum uncontinuous (small gap between anterior and posterior half), posterior half of SW almost twice as broad as anterior half ( Fig. 9A ). Epigynal field absent (or at least not recognisable); structures of vulva visible through epigynal cuticle ( Figs 9A , 71D ). Vulva with approximately oval PS directed transversally, slightly diagonally ( Figs 9B , 75G ); SS elongated oval with heads of spermathecae located postero-laterally. DST longer than diameter of PS, distal section clearly broader than proximal section, meeting PS medially. Copulatory ducts clearly recognisable and with antero-lateral direction. Fertilisation ducts arising centro-anteriorly (shifted medially) on primary spermathecae, bent laterally ( Figs 9 B–C, 75G). COLOURATION (both females old, partly bleached and many of the hairs rubbed off): see genus description for conservative aspects. Carapace dark red-brown ( Fig. 61D ). Legs brown to red-brown, except for some articles being lighter (see genus description) ( Fig. 61D ). Opisthosoma like noted in genus description under general dorsal colouration, except for chevron-like patch in central band missing (at least not recognisable) ( Fig. 61D ).

Remarks. By having an uncontinuous septum of epigynal windows, this species is similar to C. concinna sp. nov. and C. conferta sp. nov. Hence, these two species might be close relatives of C. noda .

Distribution. Known only from the type locality Cuzco ( Peru).
