Arcyphysa rossi (Kimmins) 

Diplectrona rossi Kimmins, in Mosely & Kimmins 1953  , 338, 340, fig. 233.

Material examined. Holotype ♂, Queensland, National Park [= Lamington National Park ], 1500–2000 ft, 28.ii.1921, R.J. Tillyard ( BMNH). 

Diagnosis. When viewed in lateral aspect this species resembles Arc. angusta  . The apicolateral processes on tergite X and the gonopods and the phallus show some similarity to those structures in that species, but in ventral and dorsal views the genitalia of Arc. rossi  are distinctive: the apicolateral processes are convergent and tapered to acute apices, not club shaped as in Arc. angusta  . In common with Arc. hystricosa, Arc.  fraserensis  , and Arc. diamontona, Arc.  rossi  has a sharp spine midapicolaterally on abdominal segment IX, but those species all have more elaborate lateral extensions on tergite IX/X.

Description. See Mosely & Kimmins (1953, 338, 340, fig. 233).

Distribution. Known only from the type locality in south-eastern Queensland.

Remarks. Unfortunately, no further specimens of this species have been recognised, despite examination of a considerable collection of specimens from southern Queensland, including from Lamington National Park. It is understandable that originally this species was confused with Arc. angusta  since, in lateral view, the two species show close similarity. However, the two are quite dissimilar in other respects (see Fig. 105View FIGURES 102–109, but compare Figs 104View FIGURES 102–109, 158View FIGURES 146–163, and Mosely & Kimmins 1953, fig. 223c). Given how few specimens of any Arcyphysa  species are available in collections, it is perhaps not surprising that no further specimens of Arc. rossi  have been collected.
