Dictyotus Dallas, 1851: 131, 139.

Type Species: Dictyotus tasmanicus Dallas, 1851, by subsequent designation (Kirkaldy, 1909 & Gross, 1975 - see comment below).

Included Species:

caenosus (Westwood) [image]
conspicuus Gross [image]
inconspicuus Dallas [image1, image2]
incultus (Erichson) [incertae sedis]
lincolnensis Gross
nigripes (Westwood)
roei (Westwood)
scissicollis (Herrich-Schäffer)
tasmanicus Dallas

Tribal Placement: Gross (1975) placed Dictyotus in its own group along with 2 other genera, Paradictyotus and Utheria, but he indicated a possible relationship with Laprius and Dorpius (= Myrochea) of the Myrocheini.

Comments: Kirkaldy (1909) inadvertently designated two species as type. On page XXIX, he states: “Dictyotus erected for 11 species, of which tasmanicus, roei, bipunctatus, inconspicuus, apicalis, geniculatus, and discoideus have since been removed, from the rest tasmanicus may be selected.” But on page 43 he lists “type affinis! = roei.” Gross (1975) pointed out this discrepancy, and strengthened the argument for tasmanicus as type: “Dictyotus tasmanicus Dallas, 1851 (s.d. Kirkaldy 1851 [sic]). Kirkaldy in a later page of the same publication (1909, Catalogue Hemiptera p. 43) selects Pentatoma roei Westwood. However D. tasmanicus is the first species mentioned by Dallas after the generic description.”
