Orthophana (Eupharos) tamdaoina sp. nov.

( Figs 1–8 , 17–18 )

Type material. HOLOTYPE: ♀, VIETNAM: Tam Dao National Park , 21°31'N, 105°33'E, 27.vii.2011, “I.G.31.933”, J. Constant & J. Bresseel leg. ( IRSNB).

Description. Coloration. General coloration brown or dark brown, with small light dots ( Figs 1, 2, 4 , 8 ). Each fore wing (tegmen) with several yellow dots (patches) on veins, three yellow patches on marginal vein, and three black spots (patches) each on R furcation, between branches of M vein distally, and between M and CuA near to wing middle. Caudo-dorsal angles of wings almost black. Hind wings not transparent, with veins light yellow proximally and brown or black distally ( Fig. 3 ).

Structure. Metope relatively wide, weakly enlarged above clypeus, without intermediate carinae ( Fig. 4 ). Lateral margins of metope slightly leaf-like flattened ( Fig. 2 ). Metopo-clypeal suture horizontal, deep. Postclypeus convex, without carinae. Ocelli present. Second (first visible) segment of rostrum 1.5 times as long as third (second visible) segment. Border between coryphe and metope smooth, without carina ( Figs 1, 2 ). Coryphe transverse, almost four times as wide as long medially, without carinae, anterior margin weakly convex, posterior margin weakly concave. Pronotum without carinae, anterior margin strongly convex, posterior margin almost straight. Paradiscal fields of pronotum wide behind eyes. Paranotal lobes of pronotum wide, long, without carinae. Mesonotum nearly 1.3 times as long as pronotum medially, with median and lateral carinae. Fore wings crescentic ( Figs 1 , 8 , 17 ), with distinct caudo-dorsal angles, without hypocostal plate. Basal cell very narrow, oval. Fore wing (tegmen) venation ( Fig. 17 ) as follows: many transverse veins present in precostal area, costal area and between longitudinal veins; costa separate, simple; Sc+R running as a common stem from the basal cell and furcating in proximal half of wing; M furcating in proximal half of wing after R; CuA furcating in distal half of wing (Sc+R 2 M 2 CuA 2); second branch of cubitus anterior running as marginal vein as well; clavus as long as 3/4 of wing length, open (Pcu+A 1 running to apex of clavus), Pcu and A 1 joined at middle of clavus. Hind wings well-developed, trilobed, with a coupling lobe and two weak lateral clefts ( Figs 3 , 18 ). Costal margin distinctly concave, with setae proximally. Hind wing venation: Sc+R, CuA, Pcu, A 1, and A 2 each with two branches; M and CuP simple; A 1 furcating near to wing middle, other veins furcating in distal half of wing; intermediate veins: single vein between second branch of R and M and between M and first branch of CuA distally and between A 1 and A 2 basally; second branch of CuA and first branch of Pcu closely situated apically but not joined; CuP joining anterior branch of Pcu distally and not reaching wing margin; second branch of A 1 weak. Hind tibia with two lateral spines distally and 9 apical spines. First and second metatarsomeres almost equal in length, both with two latero-apical spines, ventral surface with long setae. First metatarsomere with 10 intermediate apical spines arranged in arc.

Female genitalia. Anal tube narrow, enlarged apically, with apical part turned down at right angle ( Figs 5–6 ). Gonoplacs flat, nearly square ( Fig. 5 ), with many marginal denticles ( Fig. 7 ). Anterior connective laminae of gonapophyses VIII narrow, with teeth ( Fig. 7 ).

Male genitalia. Male unknown.

Total length. 14 mm.

Etymology. Adjective derived from the name of the type locality – the Tam Dao forest in Vietnam ( Fig. 9 ).

Ecological note. The species was collected during the night on fern ( Fig. 8 ).
