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 : 375-380

Armorseliza nigromaculata sp. nov.

Etymology. The specific epithet is derived from the Latin words “niger” meaning black and “macula” meaning “spot”.

Diagnosis. This new species resembles Armorseliza lignaria ( Walker, 1851) n. comb., but can be differentiated by the following characters: mesonotum ( Fig. 63 ) without carinae; apex of aedeagus ( Figs 67 , 72, 79 ) with a pair of small cephalad teeth; apical fourth of aedeagus with pair of cephalad and 2-branched processes.

Description. Size. Body length 8.5–9.8 mm.

Coloration. Head brown, margins of frons slightly darker, clypeus with oblique stripes; frons light brown with two black dots at top; eyes black, ocelli red; pronotum and mesonotum brown, mesonotum with three black dots at front, disc light brown, legs light brown; tegmina brown, with an oval dark spot in the middle, Y-stem of clavus dark brown.

Head: Head ( Fig. 63 ) including eyes slightly narrower than pronotum; vertex wider than long, rounded into frons; anterior margin truncate or slightly concave; lateral margins raised; posterior margin shallowly emarginate, disc depressed, almost covered by anterior margin of pronotum. Frons ( Fig. 65 ) wider than long; widest part at midline, lateral margins raised, median longitudinal carina slightly raised at dorsal portion, obsolete at ventral portion. Frontoclypeal suture shallowly convex; clypeus ( Fig. 65 ) convex. Rostrum extending to meta-trochanter. Ocelli present. Antennae very short ( Fig. 64 ).

Thorax. Pronotum ( Figs 63, 64 ) with anterior margin truncate, median carina weakly visible, postocular eminences conical. Mesonotum ( Fig. 63 ) with anterior margin convex; disc flat, without longitudinal carina. Metatibia with six spines apically; metatarsal basal segment with ten spines apically.

Tegmen ( Fig. 62 ). Tegmina elongate, about 2.3 times longer than wide, costal membrane wider than costal cell at the level of bulla ( Fig. 62 ); costal margin sinuate, apical margin convex. Three veins (Scp+R, Mp, CuA) arising from basal cell, Scp+R stem very short, ScP+RA crossing raised bulla; Y-stem of anal veins short and highly raised; one subapical line present.

Male terminalia. Pygofer ( Fig. 66 ) ring-like. Genital style ( Fig. 66 ) isosceles triangular, ventral margin convex, apical margin oblique, as long as dorsal margin, with single process at dorsocaudal portion. Anal tube ( Figs 66, 69 ) evenly arched, apex bipartite in dorsal view. Phallic complex ( Figs 67, 68, 70 , 77, 80, 83 ) slightly arched; periandrium ( Figs 71, 73, 75, 78, 81, 84 ) tubular, dorsal part membranous, dorsolateral emargination shallow; lateral emargination moderately wide; dorsal lobe produced caudad, lateral lobe with a narrow, 3-branched process, ventral lobe slender with a row of small teeth, apex of ventral part acute. Aedeagus ( Figs 72, 74, 76, 79, 82, 85 ) bipartite, each side of apex with a pair of small cephalad processes; a pair of long, cephalad and 2-branched processes at apical fourth of dorsal part; lateral part with a small prominence beneath a hooked process.
