Volynkin, Anton V. & Saldaitis, Aidas, 2020, A new species of the genus Parabitecta Hering, 1926 from Northern Vietnam and Southwestern China, with notes on the taxonomy of the genus Manulea Wallengren, 1872 (Lepidoptera: Erebidae: Arctiinae: Lithosiini), Ecologica Montenegrina 38, pp. 107-113 : 111-112

Parabitecta secunda Volynkin & Saldaitis , sp. nov.

( Figs 1–3 , 7, 8 , 11 )

Type material. Holotype ( Figs 1 , 7 ): male, “ Vietnam (N), Mts Fan- si-pan, W-side, Chapa, 22°20’N 103°40’E, 1600–1800m, Apr. 1994, leg. Sinajev [Sinyaev] & loc. coll.”, slide ZSM Arct. 2020-154 Volynkin (Coll. MWM/ ZSM).

Paratypes. VIETNAM: 3 males, 16 females, the same data as the holotype, slides ZSM Arct. 2020-153 (male) and 2020-155 (female) Volynkin (Coll. MWM/ ZSM) ; CHINA: 1 male, Sichuan, Gongga Shan , 2200m, 29°41’N 101°58’E, 25. V .–08. VI .2001, leg. Sinyaev & local coll., slide ZSM Arct. 2019-967 Volynkin (Coll. MWM/ ZSM) .

Diagnosis. The forewing length is 19–20 mm in males and 22 mm in females. The new species differs clearly from the type species of the genus, P. flava in its brown body and wing coloration. Additionally, in the Vietnamese population a postmedial costal stroke is present (absent in P. flava ). The male genitalia of the two species are similar, but P. secunda can be distinguished by the slightly broader uncus, the larger juxta, the more elongate distal spine originating from the tip of the distal saccular process (it is short and originates subapically in P. flava ), the somewhat broader aedeagus, and the presence of a quite large lateral cornutus in the aedeagus vesica (whereas in P. flava it is absent or present as a tiny denticle). The female genitalia of the new species differ from those of P. flava more conspicuously than the male genitalia by their much larger pocket-like antevaginal plate, the slightly broader ductus bursae, the broader gelatinous enlargement of the posterior section of the corpus bursae, and the slightly broader appendix bursae.

Distribution. The new species is known from Northern Vietnam (Lào Cai Province) and Southwestern China (Sichuan Province).

Etymology. 'Secunda' means 'second' in Latin; referring to the new species is being the second known member of the genus Parabitecta .
