A new species of Anorthoa Berio, 1980 from Vietnam (Lepidoptera: Noctuidae, Orthosiini)

Una nueva especie de Anorthoa Berio, 1980 de Vietnam (Lepidoptera: Noctuidae, Orthosiini)

Introduction

Anorthoa Berio, 1980 is a genus in the subfamily Hadeninae, tribe Orthosiini (BERIO, 1980, 1985). According to RONKAY et al. (2001), it is closely related to the genera Perigrapha Lederer, 1857 and Harutaeographa Yoshimoto, 1993, in particular, the rama-lineage of the latter. The genus has contained nine known species, they can be separated into three lineages. The proper taxonomic interpretation of these lineages is still disputable. Latest additions of the taxonomy of the genus were given by RONKAY et al. (2010) and OWADA et al. (2015). Present paper contains the description of a new species found recently in Vietnam, thus the number of species in the genus is raised to ten.

Material and methods

Abbreviations used:

ASZK = private collection of Attila Szabó (Kiskunfélegyháza, Hungary)

BBT = private collection of Balázs Benedek (Törökbálint, Hungary)

HNHM = Hungarian Natural History Museum (Budapest, Hungary)

HT = holotype

PT = paratype

TB = genitalia preparation of Balázs Tóth

Specimens were collected by using artificial light and were examined using modern dissection standards for Lepidoptera genital preparation. Genitalia were stained with eosin. Adults were photographed with an Olympus Camedia 7070 digital camera, genitalia slide with an Olympus DP70 photographic microscope, using the software DPController and DPManager. Images were adjusted and plates were prepared with the software Adobe Photoshop CS6.

Anorthoa dudi Benedek & Tóth, sp. n. (figs 1,4)

Type material: Holotype 1 (&) (Figs 1, 4), “Vietnam, Kon Tum prov., Ngoc Linh mt, 1700 m, February 2017, leg. local collector”, slide No. TB2038f (coll. ASZK).

Diagnosis: Externally, the new species (Fig. 1) differs from the related species A. polymorpha (Fig. 2) and A. fabiani (Fig. 3) by its slightly larger size (wingspan of A. polymorpha and A. fabiani females 43-44 mm, sp. n. 45 mm) and broader, apically less acute but more rounded forewing shape. The female genitalia of the new species (Fig. 4) differ from those of the two related species by the configuration of its appendix bursae which is much shorter and not helicoid, but terminally ovoid, sack-like, and more sclerotized than in the other two species. (Figs 5 and 6, respectively)

Description external morphology of adult (Fig. 1): Wingspan of female holotype 45 mm, forewing length 22 mm. Female antenna filiform. Forewing broad, triangular with rounded apex. Ground colour of frons, thorax and forewing unicolorous ochreous-brown, abdomen darker: fumous brownish-grey. Forewing with very sparse reddish-brown irroration being slightly denser on marginal field than on rest of the wing; ground colour decorated with two faded, reddish-brown subterminal patches: one of them at costa subapically, other on vein M2. Basal line marked with two, antemedian fascia by three tiny black dots on veins; postmedian fascia more distinct, marked by one black dot on each vein from M1 to dorsum. Terminal line represented by blurred greyish patches between veins. Orbicular spot invisible. Reniform very small, slightly darker than ground colour, lunular in shape. Forewing cilia short, with same colour as forewing. Ground colour of hindwing fumous brownish-grey, same as of abdomen, darker than forewing, veins and discal spot darker than ground colour, latter oblong, somewhat lunular; basal and apical thirds of cilia somewhat lighter than ground colour of wing, ochreous-brown, the basal third the lightest, pale yellowish; medial third with same colour as hindwing. Underside of forewing darker than upper side, ground colour like upper side of hindwing, postmedian fascia represented by dark patches on all veins, marginal field somewhat lighter than rest of the wing, terminal line like on upper side, no further pattern. Hindwing underside lighter than its upper side, ground colour like that of forewing upper side, discal spot prominent, postmedian fascia and terminal line like those of forewing underside.

Female genitalia (Fig. 4): Papillae anales oblong, not sclerotised, rather small and moderately setose with two small, digitiform projections at the edges. Apophyses anteriores short but thick, apophyses posteriores longer and narrower thinner than apophyses anteriores. Ostium bursae broad, flattened. Antrum large, broad, oblong in shape, terminally slightly widening, heavily sclerotized. Ductus bursae short, much less sclerotized than antrum, membranous, medially contracted. Appendix bursae huge, sack-like, pyriform in shape, gelatinous and strongly ribbed, its connection to the ductus and cervix covered with a heavily sclerotized and ribbed plate. Cervix bursae small, conical in shape, membranous but ribbed. Corpus bursae ovoid, membranous with two shorter and two longer, longitudinally directed, narrow signum bands, whole surface with shallow longitudinal ribs.

Male unknown.

Distribution and bionomics: The new species are known only from its type-locality. The preimaginal stages and the foodplant are unknown.

Etymology: The new species is dedicated to Ms. Zsuzsanna Valentin-Bodor.
