Diagnosis
Ianeirina are medium sized to large, ivory to brown leafhoppers. They can be identified by their somewhat long and slender habitus, anterior margin of the head usually with numerous carinae (shagreen and rounded to face in Ianeira ), ocelli on the face below the anterior margin of the head, male pygofer without macrosetae, subgenital plates fused basally and to the valve (not fused in Bardera ), and segment X well-sclerotized, large to very large, sometimes occupying most of the dorsal side of the pygofer.
Description
HEAD. Head subequal to, wider than, or distinctly narrower than pronotum. Discal portion of crown glabrous with radial or longitudinal striae. Anterior margin of head shagreen, with numerous transverse striations, or with numerous carinae. Frontoclypeus narrow; not tumid; texture shagreen. Clypellus 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 weakly developed (carinate or weakly carinate). Ocelli present; close to or distant from eyes; on face just below anterior margin of head.
THORAX. Pronotum lateral margin carinate; lateral margin shorter than basal width of eye.
WINGS. Forewing macropterous; appendix restricted to anal margin; with 3 anteapical cells; veins not raised; with or without reflexed costal veins; A1-A2 crossvein present.
LEGS. Profemur with AM1 seta only or with AM1 and with one or more additional proximal setae; 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+2+1. Metatarsomere I not expanded apically; plantar setae simple, tapered.
MALE GENITALIA. Valve articulated with pygofer; lateral margin short, articulating with pygofer at a point. Pygofer basolateral membranous cleft present, macrosetae absent or reduced (≤ two rows). Subgenital plates free from each other and articulated with valve ( Bardera ) or fused to each other basally (apices of plates usually separated) and to valve ( Abimwa , Ianeira ); without macrosetae or macrosetae scattered, irregularly arranged. Style broadly bilobed basally, median anterior lobe pronounced; sometimes reduced in size ( Abimwa , Ianeira ). Basal processes of the aedeagus/connective absent or reduced or present, connected or articulated to connective or near base of aedeagus.Aedeagus with single shaft and gonopore. Connective anterior arms somewhat divergent, Y - or U -shaped; articulated with or fused to aedeagus. Segment X well-sclerotized; large to very large, sometimes occupying majority of dorsal side of pygofer.
FEMALE GENITALIA. Pygofer with numerous macrosetae. Ovipositor not protruding far beyond pygofer apex. First valvula convex; dorsal sculpturing pattern strigate; sculpturing reaching dorsal margin, without distinctly delimited ventroapical sculpturing. Second valvula broad, gradually tapered; with dorsal median tooth; teeth on apical 1/3 or more; teeth small, regularly or irregularly shaped.
Geography and ecology
Distribution: Afrotropical.
Remarks
Ianeirina contains 4 genera and 13 valid species. Males of Kanziko Linnavuori & Al-Ne’amy, 1983 are not known. There is variability in the condition of the anterior margin of the head (rounded to face and shagreen in Ianeira , and with numerous irregular carinae in the other genera) and the condition of the male genital capsule (plates and valve articulated in Bardera and fused in Ianeira and Abimwa Linnavuori, 1978 ) among the genera. The monophyly of the tribe needs to be tested in a more thorough phylogenetic analysis. One representative of Ianeirini, Abimwa , was included in phylogenetic analyses and was found to be closely related to other Selenocephalini and in some analyses to Dagama Distant, 1910 (Athysanini) .
