Diagnosis. Artines bamba sp. nov. differs from the other species of the “ aepitus group” in the following combination of characters: harpe with ventral process narrow and cylindrical, strongly arched inwards and distally pointed, with long and thick setae on subapical portion; cornutus with long and robust spines, curved at base and directed anteriorly; proximo-lateral projections of lamella postvaginalis developed; ductus bursae with sclerotized plates.
Description. Male (Fig. 13 A–B). Head: antenna with nudum bearing 12 segments.
Forewing length: 12–15 mm.
Dorsal forewing (Fig. 13A): two or three apical spots (absent in most specimens); discal spots absent or reduced to a few scales; spot in CuA 2 –2A absent.
Ventral forewing (Fig. 13B): as in A. aepitus.
Ventral hind wing (Fig. 13B): apex of discal cell with few yellow scales; central black spot quadrate; blue discal spots in M 3 –CuA 1 and CuA 1 –CuA 2 quadrate.
Genitalia (Figs 35 A–L, 48): tegumen more or less quadrate, with proximal margin straight and distal margin not conspicuous (Fig. 35C), in lateral view shorter than length of gnathos; ventral arm of tegumen longer than dorsal arm of saccus (Fig. 35A). Saccus as long as tegumen+uncus, base as long as lateral margin (Fig. 35B). Uncus, in dorsal view, twice longer than wide, longer than tegumen, without disto-lateral projections, distal margin rounded (Fig. 35C). Gnathos as in the other species of the group (Fig. 35A, D). Valva three times longer than wide; sacculus elongate and about 1/2 width of valva; costa narrow and contiguous with ampulla; ampulla triangular and shorter than costa; ventral process of harpe narrow, elongate, cylindrical and strongly arched inwards, ventral margin slightly sinuous and distal end pointed, with subapical setae thick and long; dorsal process of harpe on median portion, rounded in dorsal view, wider than ventral process, apex surpassing dorsal margin of valva (Fig. 35 E–F). Aedeagus as long as valva, slightly curved dorsally; ventral projection distally round and strongly curved ventrally (Fig. 35 G–J); posterior end of cornutus wide and triangular, with spines thick, long and curved anteriorly (Fig. 48).
Female (Fig. 13 C–D). Forewing length: 13.5–14 mm. Similar to male.
Genitalia (Figs 60 A–B, 72): tergum VIII with complete spiracular opening. Sterigma triangular; lamella antevaginalis with proximo-ventral folds narrow; lamella postvaginalis without lateral fold, distal projections as in A. aepitus, proximo-lateral projections developed and bilobed. Ostium narrow surrounded by membranous areas; ductus bursae with sclerotized plates near insertion of sterigma.
Variation. As in most species of the “ aepitus group”, the variation is in the shape of the forewing marks. These marks are absent in most individuals analyzed and only the holotype has three apical spots and two male paratypes have conspicuous discal spots. The marks are present in females from Acre, Brazil.
Comments. Species similar to A. rica and A. liege sp. nov. in the genitalia, differing in the cornutus with long, robust spines directed anteriorly and ventral projection of harpe more elongated, distally pointed, strongly arched inwards, with setae on subapical portion. This species is unique among the “ aepitus group” with the sclerotized plate at base of ductus bursae (Figs 60 and 72).
The association of the female in this species was made based on the absence of apical and discal spots on dorsal forewing (see variation above) and distribution. However, in view of the fact that species are similar and different species can potentially occur in the same locality, the association is tentative and for this reason the females were not included in the type-series.
Geographic distribution (Fig. 78). The species occurs in the western Amazon. BRAZIL— Amazonas: São Paulo de Olivença. Acre: Senador Guiomard, Porto Acre. PERU— Madre de Díos. San Martin: Juanjui, Moyobamba.
Temporal distribution. This species occurs in July, September and October.
Host plant. Unknown.
Etymology. The term " bamba " is the termination of the word Moyobamba, the type locality of the species.
