Genus Setteleia Volynkin et Černý , gen. nov. urn:lsid:zoobank.org:act:3DC1E7FB-9D7B-4026-A926-749DE82F6B1A

Type species: Setteleia carota Volynkin et Černý , sp. nov.

Etymology: The genus is named after Prof. Josef Settele (Helmholtz Centre for Environmental Research – UFZ, Halle, Germany), who was very helpful in organizing the second author’s researches in the Philippines and who is actively involved in sciencepolicy processes for the conservation of Lepidoptera and biodiversity in the Philippines as well as globally. Gender is feminine.

Diagnosis: Members of the new genus ( Fig. 1 View Fig ) remotely reminiscent some species of the genera Cyme ( C. quadrifasciata (Rothschild)) ( Fig. 2G View Fig ) and Asura ( A. mimetica Rothschild ) ( Fig. 2H View Fig ) due to the shape of forewing transverse lines and the presence of a discal spot on forewing, but differ by their larger size and more diffuse and narrower transverse lines.

The male genitalia of Setteleia ( Figs. 3 View Fig , 4A– B View Fig ) are characterized by the complex of the following characters: The uncus is strongly broadened distally (an autapomorphic character) ( Figs. 3 View Fig , 4A–B View Fig ), whereas in other related genera the uncus is evenly narrow or broadened basally (e.g., in Moorasura , as shown in Figs. 4C–D View Fig ) or medially ( Barsochrista (illustrated by Volynkin and Ivanova 2017, p. 182, Figs. 7 View Fig –9) and Longarista (illustrated by Volynkin 2019, p. 100, Figs. 16–19)), or is dorso-ventrally flattened ( Xanthetis and Disasuridia ) (illustrated by Volynkin et al. 2019, p. 47, Figs. 133, 134).

The medial costal process is elongate, narrow, slightly curved, apically pointed and directed dorsally (an autapomorphic character) ( Figs. 3 View Fig , 4A–B View Fig ), whereas in other related genera ( Figs. 4C–D View Fig , 5B–C View Fig ) the medial costal process is directed ventrally or ventrally-distally. The genus Sarbine ( Fig. 5A View Fig ) also has the medial costal process directed more or less dorsally, but it is very short and tubercle-like. Another genus having a dorsally directed process of costa is Albarrania (illustrated by Volynkin et al. 2019, p. 53, fig. 157), but in the latter the process represents a straight and heavily sclerotized spur situated more distally than that of Setteleia .

The costa is broadened distally, reaching the tip of valva where forming a broad cucullus with a small ventral process (an autapomorphic character) ( Figs. 3 View Fig , 4A–B View Fig ), whereas in other related genera the costa is narrowed distally and forms a distal process (e.g., in Moorasura , Sarbine and Ammatho ) ( Figs. 4C–D View Fig , 5A–B View Fig ), or is not reaching the valva tip (e.g., in Cyme ) ( Fig. 5C View Fig ), or is narrow and lacking processes (e.g., in Integrivalvia ) ( Fig. 5D View Fig ).

The sacculus is broadened basally and subbasally and bearing a small trigonal ventral process near the beginning of the strongly narrowed distal section (an autapomorphic character) ( Figs. 3 View Fig , 4A–B View Fig ). The similar medial process of sacculus is present in some related genera such as Moorasura ( Fig. 4C–D View Fig ) and Sarbine ( Fig. 5A View Fig ), but in those genera the sacculus is conspicuously less broadened basally and subbasally.

The distal saccular process is represented by a very short, trigonal protrusion with a rounded tip (in S. witti , S. carota and S. lourensi ) ( Fig. 3 View Fig ) or is reduced ( S. bakunawa ) ( Fig. 4A–B View Fig ). Such a structure of the distal saccular process is also found in some species of Moorasura ( Fig. 4C–D View Fig ) and Fossia (illustrated by Volynkin et al. 2019, p. 48, fig. 136).

The distal membranous lobe of valva is absent ( Figs. 3 View Fig , 4A–B View Fig ).

The aedeagus vesica has an elongate and curved diverticulum (called here as the 1st distal diverticulum) generally directed dorsally and covered with numerous small and very short cornuti and granulation ( Figs. 3 View Fig , 4A–B View Fig ). The similar characteristic diverticulum is also known in the genus Asuridia only (illustrated by Volynkin et al. 2019, p. 44, fig. 120).

The female genitalia of Setteleia ( Fig. 6A–C View Fig ) are characterized by the complex of the following characters: The ostium bursae is narrower than the posterior section of ductus bursae, whereas in other related genera that is as broad as the ductus bursae ( Fig. 6A–C View Fig ).

The ductus bursae is relatively short, broad, dorso-ventrally flattened, moderately sclerotized, with slightly convex lateral margins ( Fig. 6A–C View Fig ), whereas in other related genera that is more elongate and has more or less parallel margins ( Figs. 6D–F View Fig , 7A–B View Fig ).

The posterior section of corpus bursae is moderately sclerotized and strongly rugose ( Fig. 6A–C View Fig ).

The anterior section of corpus bursae bears a large, elongate signum bursae with a narrow longitudinal groove (an autapomorphic character) ( Fig. 6A–C View Fig ), whereas in other related genera the signum bursae (if present) is round, elliptical or band-like and lacks a longitudinal groove ( Figs. 6D–F View Fig , 7A–B View Fig ).

The appendix bursae is elongate, curved anteriorly, its basal section is weakly sclerotized and rugose ( Fig. 6A–C View Fig ). Such a shape of the appendix bursae is known in the genus Ammatho s. str. ( Fig. 6E View Fig ), but in the latter the appendix bursae is not sclerotized and rugose basally. The genus Integrivalvia ( Fig. 6F View Fig ) also has an elongate appendix bursae, but it is evenly covered with numerous spinules and directed posteriorly.

Description: External morphology of adults ( Fig. 1 View Fig ). Medium-sized moths, forewing length 14–17 mm in males and 19–24 mm in females. Sexual dimorphism poorly expressed: female larger than male and has broader forewing with more elongate apex. Labial palps short, porrect. Male antenna strongly ciliate, female antenna filiform. Coloration from pale carrot orange or rusty reddish to brown. Head and thorax coloration same as that of forewing, abdomen paler. Forewing pattern consists of small black subbasal and discal dots and diffuse and wavy transverse lines fusing to each other on veins. Hindwing without pattern, in some species lightened subbasally and basally.

Male genitalia ( Figs. 3 View Fig , 4A–B View Fig ): Uncus strongly broadened distally, with pointed thorn-like tip. Tuba analis moderately broad, membranous. Scaphium narrow, moderately sclerotized. Subscaphium absent. Tegumen relatively short and narrow. Juxta more or less trapezoidal, weakly sclerotized. Vinculum robust, U-like. Valva elongate and relatively narrow. Costa nearly straight, narrow basally and medially, strongly broadened distally and forms broad cucullus bearing short ventral process. Medial costal process narrow, slightly hook-like curved, apically pointed, directed ventrally. Sacculus broadened basally and subbasally and bears small trigonal ventral process near the beginning of the strongly narrowed distal section. Distal saccular process represents very short, trigonal protrusion with rounded tip, or reduced. Distal membranous lobe of valva absent. Aedeagus elongate, straight, relatively narrow, slightly broadened distally. Aedeagus vesica broad, with three membranous short but broad subbasal diverticula and two large distal diverticula bearing areas of numerous short but robust cornuti or granulation; 1st distal diverticulum elongate, curved and generally directed dorsally; 2nd distal diverticulum broad, more or less globular. Distal plate of vesica narrow, band-like, weakly sclerotized.

Female genitalia ( Fig. 6A–C View Fig ): Ovipositor short and broad. Papilla analis rectangular with rounded corners, weakly setose. Apophyses elongate and thin, of equal length, apophyses anteriores slightly broader than apophyses posteriores. Ostium bursae slightly narrower than ductus bursae, with membranous margins. Main part of ductus bursae relatively short and broad, moderately sclerotized, dorso-ventrally flattened, with slightly convex lateral margins; anterior end of ductus bursae membranous. Posterior section of corpus bursae relatively narrow, moderately sclerotized, strongly rugose, its anterior end with granulation or small dentation. Anterior section of corpus bursae broadened, more or less globular, membranous, with large signum situated latero-longitudinally and having narrow longitudinal groove subdividing it to two equal parts. Appendix bursae originates laterally from posterior section of corpus bursae, elongate, curved anteriorly, its basal section weakly sclerotized and rugose like the posterior section of corpus bursae; distal section membranous and may be weakly rugose.

Distribution: The genus is endemic to the Philippine archipelago. It is not found on the island of Palawan belonging biogeographically to the Sundaic Region.

Species composition: The new genus comprises four species, all of which are new to science and described below.

Setteleia witti Volynkin et Černý , sp. nov. ( Figs. 1A–B View Fig , 3A–B View Fig , 6A View Fig ) urn:lsid:zoobank.org:act:A9AE4B86-2095-472C-81BD-EA62FAC0AB67

Type material: Holotype: male, “[the Philippines] Philippinen, Mindanao, Prov. Bukidnon, Mt. Dalongdong, Talakag , 40 km NW Maramag, 1300 m, 2–7.XI.1999, leg. Dr. Ronald Brechlin ”, slide ZSM Arct. 2020-136 Volynkin (Coll. MWM / ZSM).

Etymology: The species is dedicated to the memory of Dr Thomas J. Witt, a famous lepidopterist and a founder of the Museum Witt Munich having one of the largest collections of Heterocera in the world.

Diagnosis: Setteleia witti reminiscent externally S. bakunawa due to its brown coloration, but can be easily distinguished from the latter by its slightly larger size, more elongate forewing, darker body and wing coloration and more distinct transverse lines. The male genitalia of S. witti differ from those of other congeners by the uncus being broader basally and more strongly broadened distally, the cucullus being most broad in the genus, the most prominent distal saccular process, and the broadest aedeagus vesica having the largest and well-developed 1st, 2nd and 3rd subbasal diverticula. The female genitalia of the new species differ from those of S. carota and S. bakunawa by their narrow ductus bursae, shorter sclerotized and rugose posterior section of corpus bursae, shorter and more weakly sclerotized signum bursae, and smaller appendix bursae with the shorter and more weakly sclerotized basal section.

Costa nearly straight, narrow basally and medially, strongly broadened distally and forms broad cucullus bearing short ventral process with round tip. Medial costal process narrow, slightly hook-like curved, apically pointed, directed ventrally. Sacculus broadened basally and subbasally, bears small trigonal ventral process near the beginning of the strongly narrowed distal section. Distal saccular process short, broadly trigonal, with rounded tip. Aedeagus elongate, straight, relatively narrow, slightly broadened distally. Aedeagus vesica broad. 1st subbasal diverticulum extremely wide but short, membranous situated dorsally. 2nd subbasal diverticulum large, nearly globular, membranous, with weakly granulated lateral area basally, situated ventrally. 3rd subbasal diverticulum relatively small, globular, membranous, situated medially. 1st distal diverticulum elongate, broadened basally, with broad and round tip, covered with numerous small but robust cornuti and granulation. 2nd distal diverticulum broad, globular, covered with numerous small but robust cornuti and granulation. Distal plate of vesica narrow, band-like, weakly sclerotized.

Female genitalia: Ovipositor short and broad. Papilla analis rectangular with rounded corners, weakly setose. Apophyses elongate and thin, of equal length, apophyses anteriores slightly broader than apophyses posteriores. Ostium bursae slightly narrower than ductus bursae, with membranous margins.

Etymology: ‘Carota’ means ‘a carrot’ in Latin. The specific epithet refers to its pale carrot orange coloration.

Diagnosis: The new species is most similar externally to S. witti due to the similar forewing pattern, but differs clearly from S. witti as well as from other congeners by the pale carrot orange coloration. The male genital capsule of S. carota differs from that of S. witti by the uncus having the conspicuously narrower basal section and the narrower distal section, the shorter medial costal process, the narrower cucullus with the trigonal ventral process (that is broader and has a rounded tip in S. witti ), and the shorter medial and distal saccular processes. The aedeagus vesica is conspicuously narrower than that of S. witti , the subbasal diverticula are much smaller and less prominent; the 1st distal diverticulum is distally narrower, more elongate and bears smaller cornuti than that of S. witti ; the 2nd distal diverticulum is narrower and bears smaller cornuti than that of S. witti . The female genitalia of S. carota differ clearly from those of S. witti by the thicker apophyses, conspicuously broader ductus bursae with less convex margins, the longer, more heavily sclerotized and more rugose posterior section of corpus bursae, the conspicuously longer and more heavily sclerotized signum bursae, and the much longer and broader appendix bursae with longer and more heavily sclerotized basal section. The differences from S. lourensi are listed in the Diagnosis of the latter species.

Hindwing pale carrot orange, slightly lighter than forewing. Cilia pale carrot orange.

Male genitalia: Uncus narrow basally and strongly arrowhead-like broadened distally, with pointed thorn-like tip. Tuba analis moderately broad, membranous. Scaphium narrow, moderately sclerotized. Subscaphium absent. Tegumen relatively short and narrow. Juxta more or less trapezoidal, weakly sclerotized. Vinculum robust, U-like. Valva elongate and relatively narrow. Costa nearly straight, narrow basally and medially, strongly broadened distally and forms broad cucullus bearing short ventral process with round tip. Medial costal process narrow, slightly hook-like curved, apically pointed, directed ventrally.

Distal saccular process very short, broadly trigonal, with blunt tip. Aedeagus elongate, straight, relatively narrow, slightly broadened distally. Aedeagus vesica relatively broad. 1st subbasal diverticulum wide but very short, membranous situated dorsally. 2nd subbasal diverticulum small, semiglobular, membranous, with weakly granulated lateral area, situated ventrally. 3rd subbasal diverticulum small, globular, membranous, situated medially. 1st distal diverticulum elongate, narrowed and curved distally, covered with numerous various sized small but robust cornuti and granulation. 2nd distal diverticulum broad, globular, covered with numerous various sized small but robust cornuti and granulation. Distal plate of vesica narrow, band-like, weakly sclerotized.

Female genitalia: Ovipositor short and broad. Papilla analis rectangular with rounded corners, weakly setose. Apophyses elongate and thin, of equal length, apophyses anteriores thicker than apophyses posteriores. Ostium bursae slightly narrower than ductus bursae, with membranous margins.
