Mesoventrites with obvious longitudinal ridge, transverse ridge, and oblique furrow. Discrimen of metaventrites distinctly elevated. Aedeagus usually sclerotized, with symmetrical parameres; the structures of aedeagus and the shapes of parameres are usually specific for species. Female spermatheca (Fig 2-2I; Fig 3-2I; Fig 4-2I; Fig 5-2I; Fig 6-2C-D; Fig 9-3I) divided into an outer capsule and a sclerotized tube; the length and the shape of the tube can be different among species. Sternite and tergite VIII broad; posterior margins of male sternite VIII usually specific for species. Tergite IX symmetrical, connected mediobasally, narrowed apically. Sternite IX small, usually asymmetrical in male, but symmetrical in female. Tergite X distinctly broad. Sternite X in female slender and rhomboidal, with numerous setae in lower half, but absent in male.

Diochus octavii Fauvel, 1877</p><p>(Fig 8)</p><p>Fauvel, 1877: 235 (Type locality: Australe, Victoria); Fauvel, 1878: 535 (Australia); Olliff, 1887: 472 (characters; Australia); Bernhauer and Schubert, 1914: 319 (catalog); Bernhauer, 1920: 16 (Australia); Lea, 1925: 220 (characters; Australia).</p><p>Type material examined. AUSTRALIA: Victoria: Holotype: male, “Victoria / Australie” (Fauvelʼs handwriting) // “Wu[?] – Bay” (Fauvelʼs handwriting) // “TYPE” (red, printed) // “ Diochus / octavii Fvl. ” (Fauvelʼs handwriting) // “ R.I.Sc. N.B. 17.479 / Coll. et det. A. Fauvel ” (printed) (IRSNB).</p><p>Note. We examined the unique male type from the Fauvel collection (IRNB). The specimen was remounted, glued on a new card plate, aedeagus and last abdominal segments were embedded in Euparal on a plastic plate placed at the same pin as the specimens together with the original small rectangular card plate. As Fauvel (1877) mentioned in the description “Un seul exemplaire” and the specimen was labeled as “TYPE” there is no doubt that it is a holotype of the species .</p><p>Measurements.
