Genus Porcorhinus Goding

(Pl. 3G)

Porcorhinus Goding, 1903: 38 .

Type species. P. mastersi Goding, 1903: 38 , pl. I, figs. 12, 15, 16, by original designation.

Synonymy. Gudwana Distant, 1917: 189 (type species Gudwana typica Distant 1917: 189 ).

Description. Goding (1903): “Head large, porrect, quadrangular, superior surface nearly horizontal, lightly convex and furnished with a strong median horizontal longitudinal carina; ocelli below a line passing through centre of the prominent eyes, nearer to each other than to the eyes. Prothorax, for some distance from the base, convex, nearly horizontal, conforming to the base of the porrect head, after which it is broadened, vertical, and produced above each lateral angle in a large, triquetrous, conical, ear-shaped horn, which extends upward, outward and forward, the apex turned a little backward; the dorsum is very broad between these horns, and destitute of a median longitudinal carina; destitute of a posterior process, the posterior edge deeply and broadly sulcate forward. Scutellum as long as broad, the apex pointed, base rounded. Tegmina long, broad, reticulate, with numerous venules; clavus very broad at base, gradually acuminate to apex, with two veins. Wings very large, nearly equal in size to the tegmina, with the four apical cells, the first and third very long, the second shortest. Legs very long, femora slender, cylindrical and curved; tibiae slender, quadrilateral, the posterior pair with a row of denticles along the posterior edge; tarsi normal.”

Species. [1]: mastersi Goding.

Range. Australia (New South Wales: Springwood, Sydney; Queensland: Mt. Tambourine )

Host plants. Unknown.

Material examined. P. mastersi : 1 female, 1 (abdomen missing), Australia, ASCU, JRJ _Led1_145, 468 .

Remarks. Porcorhinus is monobasic. It is at once recognizable by its prominent pronotal horns, as well as its smooth texture and deep yellow color (in dried specimens).

Porcorhinus appears to belong to a group of species within the Australian Ledrini that also includes E. primitiva and L. froggatti (which may deserve its own genus), united by the perpendicular keel (Pl. 18F_1) on valvulae II of the females, the subtrapezoidal shape of the posterior margin of the pronotum (Pl. 1H, 2H–I, 3G), and the absence of coronal setae.
