male (courtesy of Oxford University Museum of Natural History, OUMNH), currently junior synonym of
M. lunatus
(23);
Menenotus diminutus
Walker, 1871
male (BMNH) (24). Scale bars: 5.0 mm.
Thorax. Pronotum with truncated postero-lateral angles, not forming a semicircle and with the posterior margin sub-rectilinear. Evaporative area black or yellow, with few setae; peritreme yellowish. Costal margin of hemelytra subrectilinear.
Abdomen. Connexiva with rounded and well-defined yellowish spots along the anterolateral margin of the segment. Pygophore at rest leaving visible an area equivalent to one third of its own length of the urotergite VII, in ventral view.
Genitalia. Male. Pygophore dark yellow, with irregular red spots laterally. Dorsal rim of pygophore subquadrangular. Posterior surface of the pygophore, in lateral view, markedly projected subapically. Cuplike sclerite projected more than twice its width in lateral view of the pygophore. Parameres slender, light yellow with the apical region of the head, dark brown; head long, almost half the total length, tapered, projected in a smooth curvature to the inner side and with ventral setae. Ventral sclerotization of the phallotheca with irregular shape. Basal plate triangular, densely sclerotized, except for the inferior portion of the transverse bridge, which is less sclerotized, about half its thickness; sclerotization of the central part of the ductifer shorter than half of length of the ligamentous processes. Processes of the conjunctiva with some points of sclerotization.
Measurements (mm), male and female, respectively. Total length: 19.9–23.1 and 23.3–24.6; width, on the posterior margin of the IV abdominal segment: 10–10.6 and 12.4–12.7. Head length: 1.5–1.8 and 1.9–2.2; width: 2.1–2.3 and 2.4–2.9. Interocular space: 1.1–1.5 and 1.3. Antennomeres length I: 3.5–4.0 and 3.9–4.2; II: 3.6–4.4 and 4.0–4.5; III: 3.1–3.9 and 3.6–3.7; IV: 2.9 and -. Pronotum length: 7.0–8.1 and 7.9–8.5; width: 9.5–11.5 and 10.5–11.4. Scutellum length: 2.4–2.7 and 2.9–3.4; width: 3.1–3.3 and 3.6–4.0.

Comments.
Menenotus diminutus
can be distinguished from
M. lunatus
by the posterior margin of the pronotum sub-rectilinear near the posterolateral angles; connexivum with a well-marked yellow spot; cuplike sclerite projected more than twice its width, in lateral view of the pygophore; and paramere slender, with a smooth curvature of the head.
