Austrimonus koebelei sp.nov.

zoobank.org:act:942E9B74-033A-4AB9-8318-09AC8FAB14E8 (Figs 5–6, 23)

Holotype, male, Sydney, NSW, 24.i.1905, Koebele ( BPBM)

Description. Head and thorax (Figs 5, 6) pale testaceous covered with fine light brown mottling except for ventral half of face. Tegmen (Fig. 5) whitish with fine light brown mottling interspersed with areas of denser brown mottling giving patchy appearance throughout.

Genitalia. Male:Subgenital plates ( Fig. 23B ) narrow, evenly tapering to apical process. Parameres ( Fig. 23C ) with preapical lobe well developed; apical process with slight preapical tooth. Connective ( Fig. 23C ) elongate with stem slightly longer than arms. Aedeagus in posterior view ( Fig. 23E ) with shafts curved dorsally, tapering to gonopore with narrow apical process extending beyond gonopore. In lateral view ( Fig.23D ), shafts narrow, finely acuminate, curved from base then straight to apex of apical process. Basal apodeme ( Fig. 23D ) very short, directed in line with shafts. Female: unknown.

Etymology. The species is named after Prof. Arthur Koebele who collected the holotype and whose collections in Australia in 1904–5 were the basis of G.W. Kirkaldy’s extensive contribution to our knowledge of Australian leafhoppers ( Kirkaldy 1906, 1907).

Comments. This species has closest similarity with M. melaleucae but differs in the structure of the aedeagus with narrow shafts mounted by a fine process directed dorsally and not bifurcated.
