Genus: Eospilarctia
Species: Eospilarctia yuennanica
Name
Eospilarctia yuennanica fansipana Saldaitis & Ivinskis & Witt & Pekarsky, 2012 ssp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
Holotype: male (Plate 1: fig. 3), northern Vietnam, Mt. Fan-si-pan, 1600-1800 m near Chapa 22°20"N, 103°40"E. Secondary forest, May 1995, leg. local collectors ex coll. A. Schintlmeister (slide No.OP1227), (deposited in ZSM/MWM).
Paratype: male, northern Vietnam, Mt. Fan-si-pan, Chapa, 1700 m NN (22°15"N, 103°46"E), June 1994, leg. Sinjaev & Einheim. Sammler (slide No.OP1226), (deposited in ZSM/MWM).
Diagnosis
The new subspeciesis larger than other Eospilarctia species and nominate Eospilarctia yuennanica yuennanica (Plates 3, 4). The pale yellow fascia of the forewings are much wider than in the nominate subspecies. Costal fascia of Eospilarctia yuennanica fansipana ssp. n. extend to the middle of discal cell and the basal fascia ends in a sharp diagonal tip. Eospilarctia yuennanica yuennanica is smaller (cotype forewing 28 mm, wingspan 59mm), forewing markings are similar except that the fascia are much narrower. In the male genitalia the valvae widen without a dorsal excision at apex; juxta with big lateral protrusions, subbasal diverticulum of the vesica has a simple mammilla form; median diverticulum is gently curved, wide.
Description
Male: Forewing length of holotype and paratype 33 mm, wingspan 66 mm. Wing pattern typical of genus; forewings’ pale yellow fascia very wide; costal fascia reaching middle of medium cell; basal fascia with sharp diagonal tip.
Male genitalia (Plate 2: figs 4–6): valvae of the same type as the nominate subspecies, but dorsal margin near apex with big excision; oval juxta with wide excision at top, lateral arms very short; aedeagus longer than valvae, gently curved; vesica with footshaped subbasal diverticulum; median diverticulum long, narrow, strongly curved with short spines.
Female genitalia: unknown.
Bionomics and distribution
Known only from the Fan-si-pan mountains in far northern Vietnam. Two male specimens were attracted to light at the end of May at elevations ranging from 1600 to 1800 m.
Etymology
The specific name refers to the type-locality of the new subspecies.
