Differential Diagnosis. The only bicolorous Central American species, it is rather similar to T. (T.) trinidadanse in its colouration and body-shape; it differs from it in the more rounded lateral pronotal margins, deeper frontal depression and in the red elytral pattern which occupies only the humeral part of the elytra; aedeagi of both species are rather similar (Figs. 80 vs. 81). Although this species is widely distributed in various biotopes of Central America its variability is negligible: except for the size only the basal colouration of elytra varies from black to intensively blue-green. It seems that T. (T.) humerale and T. (T.) trinidadanse are vicariant species.
Length: 3.2–5.3 mm.
Bionomy. Practically nothing is known about the bionomy of this widely distributed species. Some specimens from Mexico (Michoacán) were collected on flower of Croton cladotrichus; a specimen from Tehuantepec (Mexico, Oaxaca) was collected by beating of dying Acacia sp.
Sexual dimorphism. The female usually differs from the male in its larger and stouter body and in the more intense green or blue lustre of the dorsal surface; ventral surface of the female is usually concolorous, black with slight green lustre, ventral surface of the male possesses an intense green lustre which is more developed on metasternum and metacoxae so that the ventral surface of male looks somewhat bicolorous.
Distribution. Belize (new country record), Costa Rica, Guatemala (Bellamy, 2008), Honduras (new country record), Mexico, Nicaragua (new country record), Panama (new country record).
