speciation seems as dubious. The two races of L. fallax differ relatively strongly as reticularis has the forewing pattern more intensive, the orbicular stigma broader, less flattened, the subterminal line forming a broader light stripe, the hindwing marking stronger, sharper. The female genitalia of L. fallax fallax and L. fallax reticularis also show differences in the shape and asymmetry of the sclerotization of ductus bursae (see Figs 11, 12), but, as the external and genitalic differences of L. fallax and L. hoerhammeri are essentially larger, fallax and reticularis are considered as conspecific and separated only on subspecific level. The species L. fallax and L. hoerhammeri are easily separable by the diagnosis of Wagner (1931) but there are further, distinctive differences in the external features and the comparison of the genitalia of the two species have not published. The main specific features are discussed below in details: L. / fallax and L. / reticularis - claviform stigma ochreous-yellowish or light brownish - antemedial line strongly sinuous - postmedial line oblique, almost straight, not angled inwards above inner margin - subterminal line a row of arrowheads along an arcuate but not waved stripe - light pattern mainly yellowish - hindwing with well-defined crossline running close to marginal suffusion - valvae more elongated, narrower - costal lobe absent or weak, rounded - harpe longer, deeply bifurcate with almost equal arms - ovipositor longer, more conical - papillae anales shorter - ostium bursae a narrow, ribbon-like ring - ductus bursae short, almost homogeneously sclerotized - anterior part of corpus bursae with a gelatinous lateral part - fundus bursae small, globular L. hoerhammeri - claviform stigma blackish - antemedial line not or only slightly sinuous - postmedial line angled inwards above inner margin - subterminal line sinuous, marked with a pale line and a row of obsolescent arrowheads - light pattern mainly whitish - hindwing with a poorly visible crossline, marginal suffusion very weak - valvae shorter, much broader (Fig. 10) - costal lobe strong, triangular, sclerotized - harpe shorter, thicker, apical arms strongly inequal - ovipositor shorter - papillae anales longer, narrower - ostium bursae a large, flattened plate with stronger proximal sclerotization - ductus bursae longer, granulosely sclerotized, its margins much stronger - anterior part of corpus bursae without gelatinous lateral part - fundus bursae elongated, elliptical L. fallax reticularis ssp. n. appears, on the basis of the collecting data, as very local and infrequent with the flight period being shorter, somewhat earlier than that of L. hoer-
