Type genus: Achaetica Emeljanov, 1959 .

Diagnosis

Achaeticina are small, squat, brachypterous leafhoppers, stramineous, greenish, or brownish in color. They are distinguished from the other subtribes of Opsiini by the following combination of characters: forewings brachypterous and truncate, male pygofer lobes without ventral pointed processes, valve thick and strongly developed, valve wider than long, subgenital plates without macrosetae, aedeagal shafts arising from base, and ovipositor protruding far beyond pygofer apex.

Description

HEAD. Head subequal to or wider than pronotum or distinctly narrower than pronotum. Discal portion of crown glabrous with radial or longitudinal striae or shagreen. Anterior margin of head shagreen, glabrous, irregularly textured, or foliaceous. Frontoclypeus not tumid; texture shagreen or glabrous. Clypellus parallel-sided, tapering apically, or widening apically; apex following or slightly surpassing normal curve of gena. Lorum subequal to or wider than clypellus near base. Antennal bases near middle or posteroventral (lower) corners of eyes. Antennae short, less than 1.5 x width of head. Gena obtusely incised laterally; with fine erect seta beside laterofrontal suture. Antennal ledges absent or weakly developed (carinate or weakly carinate). Ocelli absent or reduced in size; on anterior margin of head if present.

THORAX. Pronotum lateral margin not carinate; lateral margin shorter than basal width of eye.

WINGS. Forewing brachypterous or subbrachypterous; veins not raised.

LEGS. Profemur with AM1 seta only; intercalary row with one row of five or more fine setae; row AV with short, stout setae. Protibia dorsal surface rounded, convex. Metafemur apex macrosetae 2+0, 2+1, 2+2, or 2+2+1. Metatarsomere I not expanded apically; plantar setae simple, tapered.

MALE GENITALIA. Valve articulated with pygofer; with short point of articulation with pygofer. Pygofer dorsoapical margin not strongly incised; basolateral membranous cleft present; macrosetae absent or reduced (≤ two rows). Subgenital plates free from each other, articulated with valve; without macrosetae. Style broadly bilobed basally, median anterior lobe pronounced. Basal processes of the aedeagus/connective absent.Aedeagus without basal hinge; shaft divided near base, with two gonopores. Connective anterior arms somewhat divergent, Y -shaped; articulated with aedeagus.

FEMALE GENITALIA. Pygofer with macrosetae reduced or absent. Ovipositor protruding far beyond pygofer apex. First valvula convex, dorsal sculpturing pattern granulose, maculose, or imbricate (with overlapping scales); sculpturing submarginal; without distinctly delimited ventroapical sculpturing. Second valvula gradually broadened medially or subapically; without dorsal median tooth; teeth restricted to apical 1/4 or less; teeth small, regularly or irregularly shaped.
