Ai, Deqiang, Wang, Yinglun & Zhang, Yalin, 2019, A new genus and two new species in the tribe Selizini (Hemiptera: Fulgoromorpha: Flatidae) with a checklist for the tribe from China, Zootaxa 4614 (2), pp. 368-382 : 375

Armorseliza acontia sp. nov.

Etymology. The species name is derived from the Greek word “aconto”, which refers to the aedeagus having a long spine.

Diagnosis. This new species can be distinguished from other species of the genus by the following characters: mesonotum ( Fig. 38 ) with median carina; apical fifth of aedeagus ( Figs 42 , 47, 54 ) with a pair of cephalad long and unbranched processes; aedeagus with a sharply short process at apical fourth of lateral portion; lateral lobe of periandrium with dorsal margin serrated.

Description. Size. Body length 8.3–9.2 mm.

Coloration. Head mottled brown, margins of frons slightly darker, clypeus with oblique stripes; vertex slightly darker than frons; eyes black, ocelli red; pronotum mottled brown; mesonotum and legs dark brown; tegmina brown with darker veins, Y-stem of clavus dark brown.

Head. Head ( Fig. 38 ) including eyes narrower than pronotum; vertex wider than long, rounded into frons; anterior margin convex; lateral margins raised; posterior margin shallowly emarginate, disc depressed, almost covered by anterior margin of pronotum. Frons ( Fig. 40 ) wider than long; widest at midline, lateral margins carinate, median longitudinal carina strongly raised at dorsal portion, weak at ventral portion. Frontoclypeal suture shallowly convex, clypeus convex ( Fig. 40 ). Rostrum extending to metatrochanter. Ocelli present. Antennae very short ( Fig. 39 ).

Thorax. Pronotum ( Figs 38, 39 ) with anterior margin slightly concave in the middle, median carina present, postocular eminences conical. Mesonotum ( Fig. 38 ) with anterior margin convex; disc flat, with weak median carina, lateral carinae absent. Metatibia with six spines apically, and metatarsal basal segment with nine spines apically.

Tegmen ( Fig. 37 ). Tegmina elongate, about 2.2 times longer than wide, costal membrane wider than costal cell at the level of bulla ( Fig. 37 ); costal margin sinuate, apical margin slightly convex. Three veins (Scp+R, Mp, CuA) arising from basal cell; Scp+R stem very short, ScP+RA crossing bulla; Y-stem of anal veins short and highly raised, one subapical line present.

Male terminalia. Anal tube ( Figs 41, 44 ) in lateral view almost straight, apically inflated and bipartite in dorsal view. Pygofer ( Fig. 41 ) ring-like, anterior margin strongly sinuate, ventral margin truncate, posterior margin convex. Genital style ( Fig. 41 ) isosceles triangular, ventral margin convex, apical margin oblique, as long as dorsal margin, with single process at dorsocaudal portion. Phallic complex ( Figs 42, 43, 45 , 52, 55, 58 ) slightly arched; periandrium ( Figs 46, 48, 50, 53, 56, 59 ) tubular, dorsal part membranous, dorsolateral emargination shallow, lateral emargination moderately wide; dorsal lobe produced caudad, lateral lobe with a wide, 3-branched process and dorsal margin serrated, ventral lobe slender, apex acute in ventral view.Aedeagus ( Figs 47, 49, 51, 54, 57, 60 ) bipartite, each side of apex with a caudad process; a pair of long and unbranched cephalad processes at apical fifth of dorsal portion; lateral portion with a sharply short process, a small prominence beneath a hooked process.
