Pseudoamycle gen. nov.

( Figs 1–27 )

Type species. Pseudoamycle polylepisae sp. nov., here designated.

Diagnosis. Body small, general coloration brown. Head distinctly narrower than pronotum, strongly projected, lacking preocular flange ( Amycle with preocular flange). Cephalic process porrect, intraspecifically variable in length, compressed, lateral sides sinuate, dorsally flat, ventrally convex, apex narrowed distally to truncate. Eyes round. Dorsal surface from lateral view not angulate at level of eyes ( Amycle with dorsal surface distinctly angulated at level of eyes from lateral view). Tegmina opaque and concolorous; MP pectinate ( Amycle with patterned tegmina except for A. amabilis (Westwood, 1842) ; MP not pectinate). Hindwing transparent except near base.

Description. Body small, less than 25 mm in total length; covered with abundant fine pilosity ( Figs 1 , 27 ).

Coloration. Head, pro– and mesothorax, legs and sterna brown, with pale granules and markings. Tegmina opaquely brown, concolorous. Hind wings proximally opaque, distally transparent. Metanotum, terga and area of mesonotum concealed by pronotum blackish; lateral sides of abdomen orangish to creamy white ( Figs 1–11 ).

Head. Base including eyes, in dorsal view, distinctly narrower than pronotum ( Figs 6–8 ). Head in dorsal view with elongate process (intraspecifically variable), laterally somewhat flattened, attenuating distally to truncate apex; sides sinuate; in cross section process dorsally flat, ventrally convex. Coryphe (~vertex) flat, trapezoidal basal portion, then at process lateral margins somewhat parallel; weak transverse ridge delimitating basal portion of coryphe from rest of surface of cephalic process, interrupted medially and sometimes vanished; median carina weak or obsolete ( Figs 6–8 ). Dorsal surface from lateral view not angulate at level of eyes ( Figs 2–5 ). Preocular flange and pleural carina of head process absent ( Figs 2–5 ). Eyes round. Ocelli between eyes and base of antennae ( Figs 2–5 ). Metope (~frons) concave in lateral view; median carina incomplete or obsolete; lateral carinae conspicuous, reaching apex of process (not reaching metopoclypeal suture; Figs 9–11 ). Clypeus with basal width about 3/5 of length; median carina weak at anteclypeus ( Figs 9–11 ). Rostrum long, reaching abdominal sternum V.

Thorax. Pronotum with anterior margin trilobed; posterior margin medially notched; median carina present; pair of fossettes at anterior half of disc ( Figs 1 , 6–8 ). Paranotal lobes expanded, foliate, with horizontal carina. Mesonotum with median carina obsolete near scutellum; intermediate carinae from hind margins at medial margins of fossettes, obsolete before midlength; lateral carinae diverging, weak or obsolete ( Figs 1 , 6–8 ).

Wings. Tegmina held tectiform; reticulation of crossveins dense over entire surface; main veins very slightly coarser than crossveins; MP pectinate in more than five branches before level of apex of clavus; CuA forked distad to first fork of MP and before level of apex of clavus, with two main branches until nodal line ( Fig. 1 ).

Legs. Prismatic, slightly flattened. Femora quadrangular and tibiae triangular in cross section. Metatibia with 4–5 lateral teeth somewhat equidistant; apically with 4–5 outer teeth, slightly decreasing in size from outermost to innermost; 2 inner teeth. Basal metatarsomere with 8 apical teeth, about as long as both subsequent.

Male genitalia. Pygofer small in relation to width of abdomen; in caudal view laterally compressed ( Figs 12– 13 , 25–26 ). Styli obovate; apex rounded; laterodorsal tooth at outer margin in basal half ( Figs 16–17 , 25–26 ). Segment X (~anal flap) large, in dorsal view subtriangular; dense pilosity at margins ( Figs 18–19 , 25–26 ).

Female genitalia. Tergum IX projected over ovipositor, dorsoventrally compressed ( Figs 20–21 ). Gonocoxae VIII broad, punctuate ( Fig. 20 ). Segment X (~anal flap) large, covering ovipositor; sides densely covered with setae ( Fig. 22 ).

Etymology. Combination of the greek prefix ψεϋδo (= pseudo, false) and the genus name Amycle . This due to the resemblance among these two taxa. The name is neuter in gender.
