Theloris Stål, 1865

Pentatoma (Theloris) Stål, 1865: 172 .

Theloris Stål, 1876: 57 , 74; Lethierry & Severin, 1893: 115; Kirkaldy, 1909: 46.

Type species. Cimex costatus Thunberg, 1783 , by monotypy.

Diagnosis. Head wider than long; each mandibular plate shorter than or as long as clypeus. Prosternum sulcate; mesosternum carinate; and metasternum flat; peritreme of metasternal gland opening ruga. Pygophore pyriform in dorsal view. Segment X with a pair of processes latero-basally; posterior portion less sclerotized than remaining areas of segment X. Crown of each paramere directed laterally, with dorsal and ventral processes forming a C-shape. Gonocoxites VIII flat, wider than long; mesial margins convex, not juxtaposed; gonapophyses VIII visible, not entirely covered by gonocoxites VIII.

Remarks. Rider et al. (2018) suggest Theloris may need to be transferred to the Cappaeini based on the length and the shape of the peritreme of the metasternal gland. A final decision about the placement of Theloris awaits a phylogenetic analysis.
