The old-world Zygonini tr. nov. (Hemiptera, Cercopoidea, Clastopteridae), with new taxa from the related Machaerotinae Author Andrew Hamilton, K. G. text Zootaxa 2014 3768 4 437 459 journal article 46336 10.11646/zootaxa.3768.4.3 1a775af7-faa0-4785-8f72-a92e1fcb08d7 1175-5326 227822 B537D07F-E104-4B7A-8FD1-5C383AADB070 Machaeropsis Melichar , redefined Machaeropsis Melichar, 1903 : 137 . Type-species by monotypy: M. valida Melichar, 1903 . Diagnosis. Antenna as in Capnodistini (Aphrophorinae) in having the postpedicel deeply withdrawn into the tip of the pedicel, bearing only a single peglike basiconic sensillum near the arista, lacking both coeloconic sensilla and surface sculpturing; antennal ledge narrow and triangular, similar to that of Hindola ( Fig. 22 B) but lacking the distinct ridges, as in Enderleinia E. Schmidt. Inner and outer apical cells of tegmen extending about equally basad; male genitalia as in Chaetophyes E. Schmidt ( Maa 1963, fig. 13 ), but style tip smaller than triangular base and theca thick, straight, with a stout spine on the anterior margin ( Fig. 14 C) resembling that of Pseudomachaerota ( Fig. 7 C). Remarks. The new species, described below, is the first time a male of this genus has been found. The superficially similar Machaeropsis and Metaenderleinia were synonymized by Maa (1963) but the male genitalia of both prove to be autapomorphous. For example, the theca of Metaenderleinia is massive and curved dorsad ( Fig. 13 B). It is anticipated that additional characters separating these genera will be found when the antennae of Metaenderleinia become known.
