Diagnosis

Stenotus binotatus differs from other Australian Stenotus species by body yellow with brown or black markings or stripes ( Figure 1 ), vertex as long as eye diameter (as in Figure 2B ), frons almost flat, clypeus 0.8× as short as eye anteriorly, labium reaching abdominal segment VI, ventral surface of genital capsule 1.5× as long as dorsal surface ( Figure 5E ), right paramere hooked ( Figure 5B ), right medial lobe of endosoma longer than left medial lobe, both medial endosomal lobes with fields of small spicules ( Figure 5A ), and posterior wall of bursa copulatrix with dorsal lobe ( Figure 6F ). Stenotus gressitti can be distinguished from this species by body yellow with reddish tinge ( Figure 1 ), frons distinctly bulging ( Figure 2E ), clypeus one-half of eye height anteriorly ( Figure 2A ), labium reaching middle of mesosternum ( Figure 2E ), ventral surface of genital capsule 1.3× as long as dorsal surface ( Figure 4E ), left medial lobe of endosoma distinctly longer than right medial lobe with fields of small spicules, right medial lobe without those spicules ( Figure 4A ). Stenotus witchelina can be recognized by the body yellow without any brown or black markings or stripes ( Figure 1 ), vertex distinctly shorter than eye diameter ( Figure 2C ), clypeus one-half of eye height anteriorly ( Figure 2D, G ), labium reaching middle of metasternum ( Figure 2F ), right paramere not hooked ( Figure 4G ), endosoma with right medial lobe bearing field of small spicules, left medial lobe without those spicules ( Figure 4F ).

Distribution

Stenotus binotatus has a broad Palaearctic distribution ( Kerzhner and Josifov 1999) and has been introduced to North America ( Henry and Froeschner 1988), Hawaii ( Nishida 2002) and New Zealand ( Eyles 1999a) from presumed European sources ( Wheeler and Henry 1992). This is the first record of this species from Australia.
