Heppner, John B. & Bae, Yang-Seop, 2018, A new species of Anthozela from Vietnam, with a list of species in the genus (Lepidoptera: Tortricidae: Olethreutinae: Enarmoniini), Zootaxa 4450 (3), pp. 394-400 : 395-398

Anthozela cypriflammella Heppner & Bae , new species

( Figs. 1–8 )

Type locality: Cuc Phuong Natl. Park, Mac Lake (alt. 155 m), Ninh Binh Province, Vietnam.

Diagnosis. Anthozela cypriflammella is superficially similar to other species of Anthozela , even those form Africa, but can be distinguished by the strong carinate ridge on the sacculus of the male genitalia and the absence of strong posterior spines on the 8th sternal plate. The female genitalia lack an accessory bursa but have a wide colliculum (usually narrower in other congeners) and a subtriangular, funnel-shape ostium.

Description. Male ( Fig. 1 ). Head ( Figs. 2–3 ): Vertex yellow-tan, mixed with some dark brown; frons same; antenna dark brown with few yellow-tan scales; scape yellow-tan, with dark brown streak dorsally; labial palpus light yellow, with apical segment light brown, mesally same. Thorax: Light yellow mixed over dark brown, more yellow posteriorly; tegulae same; venter tan-white, with light yellow-tan at neck; legs white basally and femurs, with tibia tan and with two angled dark brown rings; midtibia with spine-like scales on dorsal margin; hindtibia lustrous gray; tarsal segments alternating gray and pale tan. Wingspan 10.5–10.8 mm in males (n = 2), 10.8 mm in female (n = 1). Forewing with yellow scales scattered over black-brown on basal half of forewing, with indistinct black-brown costal strigulae, and with a cross-wing vertical fascia of silver-gray, straight mesally but very irregular distally, nearly to costal margin but interrupted by thin line of burnt-orange and a fine silver line angled from costal black-brown strigula towards apex; apical half of costa with several black-brown strigulae angled towards tornus, each separated by burnt orange, and on costal margin by light yellow; apical half of forewing otherwise reddishburnt-orange with several irregular lines and spots of silver-gray, subtermen and tornus with similar coloration; fringe black-brown, with a near-apical and near-tornal patch of light orange. Venter gray-brown with pale white on cell and cubitus and dorsal margin, with tan and dark brown strigulae on costal margin as in dorsal surface. Hindwing dark brown-gray with slightly paler area near midwing. Venter similar to dorsum but duller. Abdomen: Brown-gray; venter pale tan-white, with brown anterior line on each sternite; genital tuft brown-gray; pregenital plates as simple posteriorly concave tergal plate ( Fig. 7b ), intersegmental membrane connected to male genitalia very long (subequal to 8th segment), with dorsal setal patch on each side. Male genitalia ( Fig. 7 ) with tegumen elongated as strong reversed V-shape, with strongly convex uncus; socius laterally as curved concave plate with strong row of stout, comb-like spines directed mesally, of uniform length ( Fig. 7a ); valva elongated, setose, with slightly bulbous distal end, and saccular margin with a strong dorsally-directed carinate ridge about 1/6 of valval length from base; vinculum simple, V-shaped; juxta a narrow band with lateral flattened quadratic basal plate, elongated dorsally to narrow arms to anellus, latter with a longer emarginated flattened lateral flange-like plate; caulis dorsally with groove-like invaginated apex with wedge-shaped lateral point around phallus; phallus short and slender, slightly bulged medially, vesica with patch of about 30 cornuti as thumbtack-like spines (points directed outwardly);

Female ( Fig. 2 ). Head and Thorax: Essentially as in male, but head with somewhat paler yellow-white scaling, particularly on labial palpus; hindwing with midwing pale area somewhat more contrasting than in male. Abdomen: Female genitalia ( Fig. 8 ) elongated, with short ovipositor, papilla anales setose and flattened; sterigma a simple semicircular ring at posterior margin to simple, subtriangular funnel-shaped ostium bursae ( Fig. 8a ) equal in width to ductus bursae; colliculum somewhat indistinct and of similar width as ductus bursae; length of ductus bursae subequal to that of corpus bursae, with sinuous entry into corpus bursa as the ductus and bursae gradually widen to full bursal width; ductus seminalis emergent at posterior end of corpus bursa; corpus bursae large, ovate, with simple scobinations, and two large, elongated, thorn-like signa on lateral wall of bursa ( Fig. 8b ); secondary bursa absent.

Holotype: ♂, Vietnam, Ninh Binh Province, Cuc Phuong National Park., Mac Lake , 155m, 4–7 May 2009, J. B. Heppner (genitalia slide JBH 3491), deposited in MGCL on indefinite loan from PPRI (Hanoi, Vietnam) .

Paratypes (1 ♂, 1 ♀): 1 ♂, same data as holotype ( MGCL) ; 1 ♀, Ba Be Natl. Park, 240 m, Bac Kan Province, 21–26 Jun 2008, J. B. Heppner (genitalia slide JBH 3323) ( MGCL) .

Biology. The biology of the new species is unknown. Larval hosts have been reported for three species of Anthozela : A. anonidii Ghesquière , which has been recorded from the fruit of Anonidium manii (Annonaceae) ( Ghesquière 1940); A. chrysoxantha Meyrick , which has been recorded from Pavetta sp. (Rubiacacae) ( Meyrick 1936); and A. hemidoxa (Meyrick) , the pepper shoot borer or top shoot borer, which has been reared on shoots of pepper vine, Piper nigrum (Piperaceae) , in India ( Fletcher 1921, Devasahayam & Abdulla Koya 1993, 1994) and Indonesia ( Kalshoven 1950). Horak (2006) notes that larvae of A. hemidoxa have been found on Piper kadsura (Piperaceae) in the Ryukyu Islands, but comments that there may be more than one species of Anthozela involved.

Distribution. The new species is known only from northern Vietnam.

Etymology. The specific epithet refers to the red and yellow forewing coloration, latinized for "beautiful little flame-colored" moth.
