Sagarriella Macià, Mally, Ylla, Gastón & Huertas   gen. nov.

Type species: Coscinia romei Sagarra, 1924   . Butlletí de la Institució Catalana d´Història Natural, 2ª Sèrie. 4 (9), 195. ( Fig. 42 View FIGURES 41–44 )

Several morphological features have been found which show the taxa, hitherto known as C. libyssa   and C. romei   , form a monophyletic group, which is sister to another monophyletic group that includes the type species C. cribraria   . Based on these findings, we propose the new genus Sagarriella Macià, Mally, Ylla, Gastón & Huertas   gen. nov. for the taxa romei   and libyssa   , with Coscinia romei   as type species.

Diagnosis. The males of Sagarriella   differ from those of Coscinia   in the structure and geometry of the valvae. In Sagarriella   , these are elongated with parallel edges, and the apex (cucullus) consists of two sharp, closely associated processes, reminiscent of a crab’s claws ( Fig. 40a View FIGURE 40 ). The aedeagus is cylindrical as in Coscinia   ( Fig. 40b View FIGURE 40 ), but differs in the coecum penis, which is not globular but rather slightly pointed in Sagarriella   ( Fig. 40 View FIGURE 40 b’). Furthermore, in Sagarriella   the aedeagus has a dense group of highly sclerotized cornuti in the distal zone ( Fig. 40c View FIGURE 40 ) which is absent in Coscinia   ( Fig. 40 View FIGURE 40 c’), being replaced by a dense spot of spinules and a sclerotized plate, except in C. mariarosae   which certainly has a few cornuti in the central part, accompanied by the typical sclerotized plaque of Coscinia   . In females of Sagarriella   , the bursa ( Fig. 40 View FIGURE 40 d’) lacks the characteristic sclerotic belt of Coscinia   ( Fig. 40d View FIGURE 40 ), which makes it adopt a bilobal form, and the cervix bursae in Sagarriella   ( Fig. 40e View FIGURE 40 ) is much smaller than in Coscinia   ( Fig. 40 View FIGURE 40 e’).

Sagarriella   males differ from those of Spiris   in the absence of the clavus at the base of the valvae, which is characteristic of Spiris   ( Fig. 40f View FIGURE 40 ). Furthermore, the uncus is short, wide and apically shovel-shaped ( Fig. 40g View FIGURE 40 ) in Spiris   , whereas in Sagarriella   it is narrow, slender and apically pointed ( Fig. 40h View FIGURE 40 ). In Spiris   , the aedeagus has a bulging central part ( Fig. 40j View FIGURE 40 ) but in Sagarriella   it is evenly cylindrical ( Fig. 40i View FIGURE 40 ). In the females, the main difference is in the large, sclerotized lamella antevaginalis present in Spiris   ( Fig. 40k View FIGURE 40 ), which is small and more inconspicuous in Sagarriella   ( Fig. 40l View FIGURE 40 ).

The males of Sagarriella   differ from those of Lerautia   in the narrow, elongated uncus ( Fig. 40h View FIGURE 40 ), which is thick and broad in Lerautia   ( Fig. 40m View FIGURE 40 ). The valvae of Sagarriella   are much more slender, especially distally, as compared to Lerautia   , in which there is a process located on the distal costa ( Fig. 40n View FIGURE 40 ). The aedeagus in Lerautia   is not cylindrical ( Fig. 40o View FIGURE 40 ) as in Sagarriella   , but more funnel-shaped, with a characteristic swelling in the posterior third. In females, Sagarriella   differs from Lerautia   in the cup-shaped antrum ( Fig. 40q View FIGURE 40 ), which is wide and sclerotized in Lerautia   ( Fig. 40p View FIGURE 40 ). The ductus bursae is very broad and membranous in Lerautia   ( Fig. 40r View FIGURE 40 ), whereas in Sagarriella   it is thin and partially sclerotized ( Fig. 40s View FIGURE 40 ). The cervix bursae of Lerautia   is voluminous and partially sclerotized ( Fig. 40t View FIGURE 40 ), unlike Sagarriella   in which it is thinner and longer ( Fig. 40e View FIGURE 40 ).

Description. Imago. Small or medium size, head and thorax small, covered with scales, eyes large, palps short, proboscis of male short and functional; antenna of male bipectinate, thin and moderately long; that of female filiform. Foreleg tibia with a short spur. Forewings long, narrow and apically pointed, with a more or less marked golden orange ochre suffusion. Hindwings wide, tip acute, termen slightly concave towards tip; brown ochre in colour, submarginal zone with a fine golden orange tint. Females usually of smaller wingspan, with narrower, apically more pointed wings and paler colour. Male genitalia. Uncus tubular and lanceolate, with pointed tip; valvae rectangular, with a pointed apical cucullus and a subapical triangular process, giving the tip of the valva the appearance of a “crab claw”. Aedeagus cylindrical with a coecum slightly pointed, posterior end with a large number of small thorn-like cornuti. Female genitalia. Great disproportion of the ninth and eighth abdominal segments when compared to the rest of the genital structure, especially the bursa, which is considerably minor; ductus bursae short, strongly esclerotized; bursa membraneous ( Table 1 View TABLE 1 ).

Derivatio nominis. We dedicate the genus to the eminent entomologist Ignasi de Sagarra, the former curator of the Museum of Natural Sciences of Barcelona (MCNB) and author of the type species of the new genus.
