Genus Penthicodes Blanchard, 1845

Blanchard (1845) did not give the gender of the genus name in the original description nor did he associate it to a species name from which the gender could be ex- trapolated. According to the International Code of Zoo- logical Nomenclature (ICZN 1999), article 30.1.4.4 “A compound genus-group name ending in the suffix - ites, - oides, - ides, - odes, or - istes is to be treated as masculine unless its author, when establishing the name, stated that it had another gender or treated it as such by combining it with an adjectival species-group name in another gender form”. Hence, the correct names of the 17 taxa in Penthicodes are as follows:

Penthicodes (Ereosoma) Kirkaldy, 1906

Penthicodes (Ereosoma) astraea (Stål, 1864)

Penthicodes (Ereosoma) atomaria (Weber, 1801)

Penthicodes (Ereosoma) bimaculatus (Schmidt, 1905) Penthicodes (Ereosoma) caja (Walker, 1851)

Penthicodes (Ereosoma) caja caja (Walker, 1851)

Penthicodes (Ereosoma) caja malayanus Constant,

2010

Penthicodes (Ereosoma) celebicus Constant, 2010

Penthicodes (Ereosoma) pulchellus

Guérin-Méneville, 1838

Penthicodes (Ereosoma) quadrimaculatus

Lallemand, 1963

Penthicodes (Ereosoma) rugulosus (Stål, 1870)

Penthicodes (Ereosoma) variegatus

Guérin-Méneville, 1829

Penthicodes (Ereosoma) warleti Constant, 2010

Penthicodes (Penthicodes) Blanchard, 1845 Penthicodes (Penthicodes) farinosus (Weber, 1801) Penthicodes (Penthicodes) farinosus aerugineus (Stål, 1870) Penthicodes (Penthicodes) farinosus farinosus (Weber, 1801) Penthicodes (Penthicodes) farinosus leucosticticus (White, 1845) Penthicodes (Penthicodes) farinosus niasensis Schmidt, 1923 Penthicodes (Penthicodes) farinosus tullia (Breddin, 1901) Penthicodes (Penthicodes) nicobaricus (Stål, 1869)

Notes. (1) The species-group epithets astraea , atomaria , caja and tullia are not adjectives and therefore indeclin- able (D. Yanega pers. com., Sept. 2021).

(2) Hope (1843) described Lystra dimidiata Hope, 1843 from “Silhet” (currently Sylhet in Bangladesh, 24°54′N 91°52′E), which was later synonymized under Penthicodes (Penthicodes) farinosus by Nagai & Pori- on (1996). However, the specimen illustrated by Hope (1843) ( Fig. 1 ) actually seems to be a specimen of Penthicodes (Penthicodes) farinosus leucosticticus (White, 1845) (see illustration in Nagai & Porion 1996: pl. 4, fig. 61). The latter subspecies is well characterized by its hind wings pale blue basally with numerous small black spots arranged in rows and is only known from the Phil- ippines. There is no record of any P. farinosus specimen 90 Kawin Jiaranaisakul & Jérôme Constant

matching Hope’s illustration from Sunda region or continental Southeast Asia, which represent the area between the Philippines and Bangladesh ( Fig. 4 ; Nagai & Porion 1996: pl. 4, figs 62, 64, 67, 70); instead, all specimens examined from Sunda and the continent, lack the rows of black spots on the hind wings. Hence, we consider that the specimen collection data given by Hope is probably erroneous, and propose to remove P. (Penthicodes) farinosus from the fauna of Bangladesh.

(3) The subspecies given for P. (Penthicodes) farinosus follow Nagai & Porion (1996).
