“…A similar example from the tribe Arctiini is recently described in the Amazonian species Watsonidia fulgida Grados, 2019, where both males and females represent two separate morphotypes within one species, but with continuous variation in male genitalia among specimens of both morphotypes. As for W. fulgida ( Grados, 2019 ), the intraspecific variation in Thyrosticta dilata is not related to any sexual dimorphism (indeed the female remains unknown), nor to geographic, environmental or seasonal dimorphism, because specimens of both types were collected simultaneously in the same place, and moreover the species is known only from the Ambohitantely Reserve. Other, but more phylogenetically distant examples in Lepidoptera are: the Asian clearwing moth Bembecia rushana Gorbunov, 1992 with two differently coloured morphotypes and the African nymphalid Euphaedra eberti Aurivillius, 1896 , with two significantly different wing patterns.…”

Malagasy Syntomini (Polka Dot Moths) are one of the largest endemic lineages of Lepidoptera on the island, belonging to the Tiger Moth subfamily (Arctiinae). This diverse radiation comprises nearly 100 valid described species that share a single ancestor. Despite a monograph in 1964 by Paul Griveaud, systematics of the group greatly needs modern revision, and their distribution on the island is still poorly known. This contribution concerns the diversity of Syntomini of the Réserve Spéciale d’Ambohitantely, which protects the largest remaining, but already highly fragmented, vestige of Central Plateau rainforest in Madagascar. Here we provide an annotated checklist of the eight species occurring in the Reserve. Two species are recorded from the forest for the first time, while five endemics are until now known only from Ambohitantely. We also describe for the first time the female of Thyrosticta vestigii Griveaud, 1964 and of Maculonaclia tampoketsya Griveaud, 1969, as well as a yellow morphotype of Thyrosticta dilata Griveaud, 1964, and we redescribe and illustrate the genitalia of the remaining species. The significance of such colour pattern variation in aposematic moths and the role of this Reserve as a local centre of diversity of Malagasy Syntomini together with its importance in the protection of the biodiversity of Madagascar are discussed.

“…In both cases, genetic and morphological analyses confirmed conspecifity of the forms ( Zúbrik et al, 2019 ; Garrevoet, Bartsch & Lingenhöle, 2013 ). However, causes of variation in all three abovementioned species remain unknown ( Grados, 2019 ; Zúbrik et al, 2019 ; Garrevoet, Bartsch & Lingenhöle, 2013 ).…”

“…The most well-known examples of polymorphism are: sexual dimorphism, polyphenism, color polymorphism, and geographic polymorphism (Grados 2019). There are known species with a continuous variation in the genital apparatus of males, both within and between populations.…”

“…An example of a polymorphic species belonging to the tribe Arctiini is Watsonidia fulgida Grados, 2019. Within the species both males and females represent separate morphotypes with continuous variation in the male genitalia (Grados 2019). Many cases of polymorphism are observed within the family Geometridae, for example in Alcis repandata, Idaea aversata, or Angerona prunaria (Ford 1953).…”

The subgenus Parapisa of the genus Apisa is reviewed based on the examination of 104 specimens. Apisa (P.) cinereocostata and A. (P.) subargentea are redescribed and their intraspecific variation is analysed in detail. A new species A. (P.) asipa, similar in the general coloration to other Apisa taxa, but very distinctive in the male genital morphology and the shape of the wing scales, is described from Cameroon and Nigeria. Apisa (P.) cinereocostata is hypothesized to be a widespread, but highly polymorphic taxon with significant variation in body size, intensity of grey coloration, and the proportions and shape of certain morphostructures of male genitalia. Determination keys and extensive illustrations of the variation are provided to enable proper identification of specimens.

A series of different-looking tiger moths was collected at pyrrolizidine alkaloid baits in the daytime in Peru. They proved to be variants of a new genus, Vanewrightia gen. nov., and a new species, Vanewrightia kiesela sp. nov., both described here. This species presents a striking example of extensive intraspecific variation within a population. Its discovery demonstrates the importance of sampling moths by means other than collecting with light, of studying patterns of wing undersides, and of the value of barcoding. Specimens found in collections considered here potentially to represent further species of the new genus are documented and discussed; Vanewrightia subflavescens (Kaye, 1911) comb. nov., and Vanewrightia patawaensis (Cerda, 2017) comb. nov. are established; we propose Epidesma parva (Rothschild, 1912) as a junior synonym of E. aurimacula (Schaus, 1905). The newly recognized intraspecific variation greatly challenges delimitation of morphospecies and uncovers uncertainties in the taxonomy of Epidesma Hübner, [1819]. The occurrence of an oblique forewing band in many Lepidoptera and the stunning similarity in overall appearance of variants of Vanewrightia with unrelated taxa, in particular notodontid moths (Josiini) and Chamaelimnas C. & R. Felder, [1885] butterflies (Riodinidae), are discussed in the context of mimicry and crypsis, and some perspectives for further research are suggested.
