DD39CF9B9CD759E9902C363E094209E7.taxon	diagnosis	Diagnosis. Achyra melanostictalis is readily distinguished from African Udea species by its wing pattern in combination with the dark, uniform hindwings lacking any stigmata. The species is preliminarily placed in Achyra based on commonalities in the wing pattern. It is distinguished from A. coelatalis (Walker, 1859) and A. arida Maes, 2005 by the clearly different wing pattern; see for example https: // lepiforum. org / wiki / page / Achyra _ coelatalis for A. coelatalis, and Maes (2005) for A. arida. With A. nudalis (Huebner, 1796), A. melanostictalis shares similarities in wing pattern, and in the female genitalia in the attachment location of the appendix bursae. However, the former species is distinguished from the latter in the female genitalia by two short ovate to lanceolate signa, and by the long, coiled ductus bursae. The two species share a rounded structure in the posterior female genitalia; in A. melanostictalis, however, this is the antrum, whereas in A. nudalis this structure is located in the posterior ductus bursae, before the colliculum and antrum. The species further resembles certain species of Tegostoma Zeller, 1847 (Odontiinae), like T. comparalis (Huebner, 1796) and Tegostoma sp. ABA 4625 in the BOLD database, in wing shape, maculation and the uniformly coloured hindwings without maculation. Achyra melanostictalis can be best distinguished from T. comparalis in the female genitalia by the structure of the antrum, and the presence of an appendix bursae as well as a signum (see e. g. Chen and Wang 2013 for illustrations of the female genitalia of T. comparalis). The unusual signum (Fig. 32) of A. melanostictalis is not shared with any other Spilomelinae, Pyraustinae or Odontiinae that we know of, and may therefore act as the most unambiguous character to identify and distinguish this species.	en	Mally, Richard, Aarvik, Leif, Karisch, Timm, Lees, David C., Malm, Tobias (2022): Revision of Afrotropical Udea Guenee in Duponchel, 1845, with description of five new species of the U. ferrugalis (Huebner, 1796) group (Lepidoptera, Crambidae, Spilomelinae).

4A003BFDC6F153899D4C5016C24D110F.taxon	diagnosis	Diagnosis. Externally, L. infuscalis is easiest distinguished from Afrotropical Udea species by the long, slender forewings and the presence of a frenulum hook in the male's forewing. Lirabotys infuscalis (Fig. 10) differs from L. liralis (Legrand, 1966), the type species of Lirabotys Shaffer & Munroe, 2007, and from L. prolausalis (Walker, 1859) (see e. g. digitised holotype specimen of syn. Botys longalis Walker, 1866 at www. oum. ox. ac. uk / collections / irn / ca 3358) in the wing maculation: L. liralis and L. prolausalis lack the proximal discoidal stigma, the distal discoidal stigma is a narrow arched line, and the postmedial line is traceable from costa to anal margin, and lacks the zigzag cource of L. infuscalis. It differs from Lirabotys liralis in the male genitalia (Fig. 33) in the shape of tegumen, sacculus, fibula, valva apex, and juxta, and in the size and number of phallus cornuti; in the female genitalia (Fig. 34) in the shape of the antrum, and the absence of a signum. The genitalia of L. profusalis (or its synonym Botys longalis) have not been studied.	en	Mally, Richard, Aarvik, Leif, Karisch, Timm, Lees, David C., Malm, Tobias (2022): Revision of Afrotropical Udea Guenee in Duponchel, 1845, with description of five new species of the U. ferrugalis (Huebner, 1796) group (Lepidoptera, Crambidae, Spilomelinae).

The investigated material consists almost exclusively of females, with only one male present among the 17 specimens, suggesting that males could be less attracted by light. The material was collected at elevations ranging from 380 to 780 m above sea level in various habitats, such as mixed non-native forest, rocky, shrub-rich valleys with small pastures, Ulex - rich shrubland on rocks, vegetation mosaics formed by Phormium tenax and Acacia longifolia, and Dicksonia - Melanodendron thicket of the cloud forest zone.	en	Mally, Richard, Aarvik, Leif, Karisch, Timm, Lees, David C., Malm, Tobias (2022): Revision of Afrotropical Udea Guenee in Duponchel, 1845, with description of five new species of the U. ferrugalis (Huebner, 1796) group (Lepidoptera, Crambidae, Spilomelinae).

(2010) list host genera from nine families, although records from the Oriental region might be misidentifications of U. testacea (see " Genetic data " below and Discussion). Palaearctic records comprise Beta vulgaris (Amaranthaceae), Cichorium intybus (Asteraceae), Capsicum, Solanum lycopersicum and S. melongena (Solanaceae) as well as Cucurbita (Cucurbitaceae). In South Africa, the caterpillars feed on Lepidium capense Thunb. (Brassicaceae) according to Taylor (1951) and on Erigeron (Asteraceae) according to Robinson et al. (2010). More information about the biology of U. ferrugalis can be found in Gaedike (1980) for Central Europe, and in Lee et al. (1999, 2002) for East Asia.

17A669C115BA54A48ECFBF0C2C7BFAAB.taxon	diagnosis	Diagnosis. Udea kirinyaga is clearly distinct in maculation from U. ferrugalis (Fig. 2), U. delineatalis (Fig. 1) and U. meruensis (Fig. 7), most prominently so in the postmedial line, which runs from the costa inwards towards the distal discoidal stigma, whereas in the other species this part of the postmedial line softly bends towards the termen. Udea kirinyaga has a superficial resemblance to Achyra melanostictalis (Fig. 9), but the forewing ground colour is more yellowish, with a weak ante- and postmedial lines, and a broad diffuse subterminal band; the hindwings are pale cream-white apart from the outer margin and have a diffuse discal spot. In the male genitalia, U. kirinyaga (Fig. 24) is distinguished from U. meruensis (Fig. 26) in the rounder, U-shaped saccus, the more elongate juxta with straight sides, and the claw-shaped, pointed main cornutus in the phallus. It is distinguished from U. ferrugalis (Fig. 22) by the shape of the main cornutus, which is blunt and thumb-shaped in U. ferrugalis; furthermore, U. ferrugalis exhibits strongly sclerotised " horns " on each side of the juxta apically. The species is distinguished from the Eurasian U. accolalis by the fibulae, which are shorter and straighter in U. accolalis (see e. g., Slamka 2013, pl. 21).	en	Mally, Richard, Aarvik, Leif, Karisch, Timm, Lees, David C., Malm, Tobias (2022): Revision of Afrotropical Udea Guenee in Duponchel, 1845, with description of five new species of the U. ferrugalis (Huebner, 1796) group (Lepidoptera, Crambidae, Spilomelinae).

Wings: (Fig. 4) Forewing length of male 11 mm. Single frenulum bristle in male, condition unknown in female. Forewings with ochre to cream-brown ground colour. Faint brownish antemedian line leaving costa at 1 / 5 obliquely outward, after 1 / 3 abruptly directed straight towards anal margin. Discoidal stigmata dark brown, proximal one small, circular, distal one larger, roughly circular to short comma-shaped. Anal centre of wing with a slightly darker half-circle, slightly skewed towards - and almost reaching - proximal discoidal stigma. Postmedian line brown, only costal part clearly formed, where it leaves the costa at 2 / 3 straight inward towards distal end of distal discoidal stigma, then too faded to trace. Subterminal line a broad diffuse brown band slightly arching inwards from subapex to subtornus, on terminal side fading into subterminal area; subterminal area a lighter ochre than in proximal wing, suffused with brown scales; apical costa with two brown markings, one in apex and one slightly more proximal on costa. Veins on outer margin marked with brown dots. Brownish fringe. Hindwing ground colour cream; diffuse brown proximal discoidal stigma, indistinct distal discoidal stigma with a very faint postmedian line connecting it to the costa. Outer margin blurred light brown, broad at apex, narrowing towards tornus; veins on outer margin with dark markings; fringe a lighter brown than in forewing. Ventral wing sides like dorsal sides, but somewhat darker and maculation more contrasted, with area proximal of postmedian line dark brown versus lighter brown area distal of it, and subtornal area cream; postmedian line in hindwing continued below distal discoidal stigma as line of dark brown dots trailing off towards anal area. Abdomen: Ochre to cream-brown like forewing ground colour, first segment and posterior end of mid-segments cream-coloured like hindwings. Tympanal organs (Fig. 14) with lobulus well developed, almost as long as broad.

30791AC8BE55546F98603499B9A65687.taxon	diagnosis	Diagnosis. Udea meruensis is darker in forewing maculation than the other Afrotropical Udea species, although U. delineatalis (Fig. 4) is almost as dark, but its hindwings with a prominent distal discoidal stigma, a clear postmedian line and a distinct broad brown band from apex to tornus distinguish it from the new species. In the male genitalia, U. meruensis is distinguished from U. kirinyaga (Fig. 24) by the more V-shaped saccus, the shorter, more rounded juxta, and the stout, thumb-shaped main cornutus in the phallus. Udea ferrugalis (Fig. 22) is distinguished from U. meruensis (Fig. 26) by the larger juxta apically adorned on each side with a strongly sclerotised pointed projection. The species is distinguished from the Eurasian U. accolalis by the fibulae, which are shorter and more straight in U. accolalis (see e. g., Slamka 2013, pl. 21).	en	Mally, Richard, Aarvik, Leif, Karisch, Timm, Lees, David C., Malm, Tobias (2022): Revision of Afrotropical Udea Guenee in Duponchel, 1845, with description of five new species of the U. ferrugalis (Huebner, 1796) group (Lepidoptera, Crambidae, Spilomelinae).

FF03B7BD0CB85AF5926D50F302B7DC3C.taxon	diagnosis	Diagnosis. Externally, the single known specimen resembles most closely U. ferrugalis (Fig. 2). Forewing colouration is not a reliable character distinguishing the two species, as U. ferrugalis can be similarly coloured. Udea momella is best distinguished by the forewing postmedian line, which is a long wide arch spanning from 3 / 4 length of the costa to about 2 / 3 length of anal margin, more resembling the forewing pattern of certain Pyraustinae such as Achyra nudalis (Huebner, 1876) than that of Udea; in U. ferrugalis, the forewing postmedian line usually forms a wide half-circle around the distal discoidal stigma that leads into an oval loop on the anal side of that stigma before running towards the anal margin. Furthermore, the forewing costa is mostly straight and slightly curved in the distal 1 / 4, giving the wing apex and the entire forewing a more triangular shape, whereas in U. ferrugalis the distal 1 / 3 of the forewing costa forms a long curve, resulting in an overall slenderer forewing shape. In U. momella, the hindlegs' proximal spur pair has a minute outer spur, whereas in U. ferrugalis this spur is well developed and about half as long as the inner spur. It is also very close to U. ferrugalis in the male genitalia, especially in the shape of uncus, juxta, phallus and cornutus. The clearest differences between the two species are in the orientation of the fibula - ventrad in U. ferrugalis (Fig. 22) -, and in the shape of the fibula base, which is as long as the fibula that is protruding from it in U. momella (Fig. 25), while the base is only half as long as the fibula in U. ferrugalis.	en	Mally, Richard, Aarvik, Leif, Karisch, Timm, Lees, David C., Malm, Tobias (2022): Revision of Afrotropical Udea Guenee in Duponchel, 1845, with description of five new species of the U. ferrugalis (Huebner, 1796) group (Lepidoptera, Crambidae, Spilomelinae).

FD79C83FC23159CC90E4C60ECF8262E2.taxon	diagnosis	Diagnosis. In the Afrotropical realm, imagines of U. nicholsae most closely resemble those of U. meruensis (Fig. 7) and U. delineatalis (Fig. 1). They can be distinguished from those of U. meruensis by the fore- and hindwings concolorous, whereas in U. meruensis the hindwings are beige and much lighter than the dark brown forewings. Udea nicholsae can be distinguished from U. delineatalis by the evenly brown hind wings, whereas in U. delineatalis the hindwings are light beige in the basal area and brown in the area outside the postmedian line.	en	Mally, Richard, Aarvik, Leif, Karisch, Timm, Lees, David C., Malm, Tobias (2022): Revision of Afrotropical Udea Guenee in Duponchel, 1845, with description of five new species of the U. ferrugalis (Huebner, 1796) group (Lepidoptera, Crambidae, Spilomelinae).

FD79C83FC23159CC90E4C60ECF8262E2.taxon	description	Description of adults. Head: Dorsal side brown, ventral side beige; labial palps porrect, in females more than twice as long as eye diameter, dorsal side brown, ventral side beige; maxillary palps well developed, long enough to touch each other at apex; haustellum fully developed, basally with beige scales; frons brown, evenly rounded; compound eyes large, hemispherical; antennae brown with swollen pedicellus, flagellum about 2 / 3 length of forewing, with very short ciliation; vertex in centre and behind ocelli with tuft of long brownish scales. Thorax: Dark brown dorsally, ochre-cream ventrally. Tegulae large, dark brown, with lighter brown tip. Legs ochre-cream, proximal foreleg tarsus with brownish scales. Outer tibial spurs half as long as inner spurs, respectively 2 / 3 length of inner spur in hindlegs' distal spur pair. Wings: (Fig. 6) Forewing length of females 9 mm. Number of frenulum bristles variable in females: holotype with three bristles on one side and two on other, paratype with two bristles on both sides. Forewings with ochre-brown ground colour. Faint dark brown antemedian line leaving costa at 1 / 5 obliquely outward, at half its length abruptly directed straight towards anal margin, which it meets in a right angle. Discoidal stigmata with thin dark brown outline and slightly lighter brown filling, proximal stigma relatively large, oval, distal one larger, roughly 8 - shaped. Postmedian line dark brown, leaving costa at 2 / 3 in a bow around distal discoidal stigma, behind stigma leading straight towards forewing base, then under stigma bending into a straight line towards anal margin, running in parallel to antemedian line. Veins on outer margin marked with dark brown dots, terminal wing margin with brown line. Fringe scales basally ochre, distal 2 / 3 brown. Underside pale brown ochre, distal costa with four dark brown spots, the second one being largest; very faint greyish proximal discoidal stigma, distal stigma more clear and larger, but blurry; faint postmedian line with course as in upper side; terminal dark brown dots on veins, terminal wing margin and fringe scales as in upper side. Hindwing ground colour slightly lighter than that of forewings, except for subterminal area. Dark brown spot-like proximal discoidal stigma slightly proximal of where forewings' antemedian line meets anal margin, distal discoidal stigma smaller, in hindwing centre. More or less faint postmedian line running from where forewings' postmedian line meets anal margin, running in a bow around distal discoidal stigma, fading out towards anal margin. Veins on outer margin marked with dark brown dots, terminal wing margin with brown line. Fringe scales ochre, those at vein dots brownish. Underside beige to ochre, discoidal stigmata dark brown, large; postmedian line mainly consisting of a sequence of dark dots: one large dot at costa, a pair of dots in curve outside distal discoidal stigma, a thin diffuse line leading to another pair of fainter dots in subanal area, and a final diffuse anal dot; terminal dark brown dots on veins, terminal wing margin and fringe scales as in upper side. Abdomen: Dark brown, interspersed with ochre scales. Tympanal organs (Fig. 16) with lobulus well developed, short, broad. Male genitalia: Unknown. Female genitalia: (Fig. 30) Papillae anales simple, with long chaetae. Apophyses posteriores slender, slightly curved dorsad; apophyses anteriores about 1.5 - times as long as apophyses posteriores, thicker, widest at 1 / 4 length from the base, distal half slightly curved dorsad. Antrum simple, sclerotised, broadly funnel-shaped with posterior half with straight, roughly parallel sides and anterior half evenly narrowing to about 1 / 3 posterior antrum width. A short membranous section leads to colliculum; colliculum tubular, twice as long as broad, sclerotised except for a broad longitudinal membranous dorsal strip. Ductus bursae about as long as colliculum, slightly thinner. Ductus ejaculatorius attached at about 1 / 4 length of ductus bursae from colliculum. Corpus bursae large, ovate, membranous, anteriorly with minor longitudinal constriction, separating the corpus bursae into a shorter side and a longer one bearing the signum. Signum large, dentate, longitudinally oriented, broadest in anterior half of corpus bursae, anterior and posterior parts drawn out into long tapering arms, with posterior arm about twice as long as anterior one.	en	Mally, Richard, Aarvik, Leif, Karisch, Timm, Lees, David C., Malm, Tobias (2022): Revision of Afrotropical Udea Guenee in Duponchel, 1845, with description of five new species of the U. ferrugalis (Huebner, 1796) group (Lepidoptera, Crambidae, Spilomelinae).
