Anchises Stål, 1867

Type species: Anchises sulcicornis Stål, 1869 (= Halys parvulus Westwood, 1837 ), by subsequent monotypy.

Anchises Stål, 1867: 509–510 (barren genus; keyed); Stål, 1869: 228 (type species); Stål, 1876 37, 45 (keyed); Lethierry & Severin, 1893: 100 (synonymy); Kirkaldy 1909: 195. (taxonomic position); Horváth, 1915: 225, 249–250 (description, keyed); Gross 1976: 255 (descriptive note, taxonomic position)

Redescription. Head slightly longer than broad, punctate; vertex flat; juga acute apically, rounded laterally; antennifers stout, acute, visible from above. Antennal segment I subequal with apex of head, distal third wider than proximal portion; remaining segments of antennae slightly dorsoventrally compressed. Compound eye subglobose, slightly stalked; ocelli posterior to imaginary line between posterior margins of eyes. Pronotum deeply punctuate; disc slightly depressed; gibbosities of callus areas hardly raised; anterolateral margins sinuate, denticulate; lateral angles acute; posterolateral margin smoothly transitioning into posterior margin. Scutellum elongate, triangular, with low, median, raised longitudinal line; apex acute. Forewings just surpassing abdomen; corium shallowly punctuate. Laterotergites totally exposed from above; posterior angle slightly produced.

Bucculae parallel-sided, becoming obsolete upon reaching posterior margin of head; anterior angle of bucculae acute, directed anteroventrally. Labium elongate, surpassing metacoxae. Prosternum sulcate; mesosternum slightly depressed with median raised carina, posterior margin shallowly bilobed. Metasternum shallowly sulcate, swollen laterally, posterior margin concave; peritreme elongate, curved anteriorly. Posterior margin of metapleura straight to slightly curved, posterolateral lobe absent. Legs unarmed. Abdomen with venter primarily convex, flattened to slightly sulcate medially, posterior margin of sixth sternite (fifth visible) “V”-shaped; trichothoria paired, transverse, posterior to spiracles.

Males. Dorsolateral lobes of pygophore weakly developed. Proctiger with anus at apex. Paramere reduced, fused to interior portions of proctiger. Proctiger with an apical anus; basal sclerite well-developed.

Females. Secondary thickening of vaginal intima long, conical.

Comments. Anchises is the only Australian member of the Solomonius -group. The male and female genitalia of the group are reminiscent of Brizica , although the proctiger does possess an apical anus. However, the shape of the peritreme, the lack of woolly pubescence on the dorsum, and the compression of the antennal segments make this genus distinct from Brizica .
