Taxonomic note. Hacker et al. (2012) treated the species as a Meganola without studying the genitalia of the female holotype. As the facies of the species is highly reminiscent of Meganola nanographa Hacker, 2012, the examination of the holotype genitalia of Celama argyropasta was crucial in order to elucidate its generic position and test the validity of Hacker’s taxon. The dissections of the C. argyropasta holotype collected in Ghana, and a series of DNA barcoded West African and Gabonese specimens of both sexes have revealed that the West African argyropasta and M. nanographa described from Uganda belong to the genus Hampsonola rather than to Meganola. In the male genitalia, the two species are distinguished by the less dilated dorsal arm of the valva and the considerably more curved aedeagus of H. nanographa. The females of the two taxa differ in the somewhat longer apophyses and considerably larger signa bursae of argyropasta compared to the Gabonese specimens. Analyses of DNA barcodes have confirmed the conspecifity of the Gabonese specimens and the holotype of M. nanographa (BOLD process/DNA barcode id.: GWOSG784-10/BC ZSM Lep 41781), and furthermore, a pairwise distance of 3.31% was calculated between the West African H. argyropasta and Central African H. nanographa, corroborating the observed morphological divergence. Consequently, H. argyropasta and H. nanographa are confirmed here as distinct species and transferred to the genus Hampsonola: Hampsonola argyropasta (Hampson, 1914) comb. n., Hampsonola nanographa (Hacker, 2012) comb. n.
Description of the male genitalia (Fig. 24). Uncus short, narrow, gradually tapered, apically pointed. Tegumen long and narrow. Subscaphium short and narrow, weakly sclerotized, proximally finely scobinate. Valva broad at base, costal lobe long and narrow, apically slightly clubbed, ventral lobe short, ventral margin evenly rounded, dorsal margin produced into a short point. Medio-distal part of valva with a short rugged crest bearing long androconial scales. Sacculus short and broad, trapezoidal; harpe very long, slightly S-curved, apically dilated and rounded, twice as long as length of ventral valval lobe. Juxta short, simple, overturned C-shaped. Vinculum moderately long, very narrow, apically pointed. Aedeagus short and thin, slightly S-curved, postmedially tapered, apically slightly dilated bearing a rounded subapical plate; coecum penis short, rounded; vesica without cornuti or scobination.
Description of the female genitalia (Figs 34–35). Ovipositor rather short and broad, papilla analis trapezoidal, posterior apophysis rather long and thick. Eighth tergite very short, medially constricted, anterior apophysis almost as long as posterior one, rather thin. Ostium bursae moderately sclerotized, cup-shaped, ductus bursae tubular, relatively long, moderately thick; cervix bursae unmodified, ductus seminalis relatively thick. Distal tubular part of corpus bursae short, ca. one-fifth of length of bursa, dilated proximal part of corpus bursae ovoid, with two welldeveloped, apically acute, more or less thorn-shaped signum situated wide apart from one another.
Genetic information. The species has been assigned the BIN URI: BOLD:AEK6843. The intraspecific divergence based on two samples is 1.08%. The nearest neighbour of H. argyropasta is H. nanographa with a pairwise distance of 3.31%. The genetic divergence between H. argyropasta and H. elachistomorpha is discussed under the latter species.
