Genus Entisberus Distant, 1903

( Fig. 1 )

Entisberus Distant 1903:74 .

The genus Entisberus was described originally by Distant (1903) and was redescribed by Distant (1904), Bergroth (1918) and Kondorosy (2008). The diagnostic characters include the following:

Description. Head triangular and not exserted; eyes not stylate, but prominent and adjacent to anterior margin of pronotum, with at least part of eye projecting beyond antero-lateral corners of pronotum; antennal tubercles clearly visible from above; antennae with relatively long, outstanding setae, with first segment at least half surpassing apex of head; bucculae not terminating posteriorly in a distinct spine; rostrum just surpassing fore coxae, with first segment not attaining base of head. Pronotum with two distinct lobes on disc, and laterally distinctly impressed at level of dorsal separation of lobes; laterally angulate, but not distinctly carinate; anterior margin with distinct punctate collar, but this not separated from disc by a distinct sulcus; disc distinctly punctate, with punctures on posterior lobe and collar larger than those on anterior lobe; postero-lateral angles prominent or slightly angulate, with corner often somewhat excised; posterior margin slightly impressed at basal angles of scutellum. Scutellum with a distinct Y-shaped, pale elevation. Hemelytra macropterous; clavus with three parallel rows of punctures; corium with two parallel rows of punctures adjacent to claval suture, and outer half distinctly, but irregularly punctate; anterior margin of corium narrowly impunctate, sinuate and sometimes somewhat serrate; apical margin of corium at most slightly sinuate, concave near inner angle; membrane with distinct veins and dusky patches. Fore femora not greatly incrassate, but unarmed with spines. Abdominal venter with sutures between sterna is replaced by coarse striate bands.

Kondorosy (2008) listed other characteristics of Entisberus to separate this genus from Retoka China, and illustrated both genera. Distant (1904) and Zheng and Zou (1981) also illustrated the type species, Entisberus archetypus Distant, 1903 . Kondorosy (2008) moved the species described as Entisberus gibbus Zheng (Zheng and Zou 1981) and E. esaki Slater & Hidaka (Slater & Hidaka 1958) to the genus Retoka.
