Species Sogatellana geranor (Kirkaldy, 1907)


Compiler and date details

31 December 2010 - Murray J. Fletcher

 

Introduction

This species was described by Kirkaldy (1907) from macropterous males as Delphax geranor Kirkaldy and from brachypterous females as Megamelus sponsa Kirkaldy, both from Cairns in the wet tropics of North Queensland. Asche & Wilson (1990) refer to a holotype for M. sponsa (which they list in the genus Delphax) but Kirkaldy (1907) states that he has "seen only brachypterous females" which implies that he had more than one specimen, which are therefore syntypes. Asche & Wilson's (1990) reference to a "holotype" does not constitute a lectotype designation (ICZN Article 74.5).

Diagnosis

Male: Superficially like [kolophon], but narrower and longer, keels more pronounced, etc.; median longitudinal stripe from head to scutellum whiter. Frons intercarinally fuscous. The male genitalia are also very different. Pygophor rather elongate viewed end-on, and thickened inwardly at the sides. The anal tube has a lateral spine on each side directed downwards and apparently 2 downwardly and outwardly directed spines between the above. Aedeagus of remarkable form. Lip produced somewhat in the middle. Genital styles contiguous longitudinally at base, diverging, their lateral margins angulate in the middle, apically truncate, the apical angles on each side being acute. Length 3.3 mm. (Kirkaldy 1907, as Delphax geranor).
Female: Pale ferruginous, a broad ivory white stripe from apex of head (dorsally) to apex of abdomen. Beneath pale ferrugino-testaceous, legs testaceous, frons medianly rather broadly ivory white. Tegmina subhyaline, tinged with yellowish, subcosta and commissure, ivory whitish. Head slightly produced in front of eyes. Antennae reaching well beyond base of clypeus, first segment nearly as long as the second. Tegmina reaching a little beyond apex of abdomen, but membrane scarcely formed. Length 3.3 mm. (Kirkaldy 1907, as Megamelus sponsa).
