Information: Physomeloe corallifer was described by Germar in 1818.
P. corallifer is an endemic species of the Iberian Peninsula, widespread in specific habitats.
The adult of Physomeloe corallifer is a wingless, robust blister beetle with a black, subopaque body. The head and pronotum are slightly shiny, with the pronotum bearing two prominent, bright red lateral tubercles — a key diagnostic feature. Body length ranges from 11 to 32 mm, and elytra width from 6 to 10 mm. The head is subtrapezoidal with a deep median furrow and coarse punctation, particularly on the frons. The antennae are filiform, reaching the pronotal base, with basal segments shiny and distal segments darker, bearing short, appressed microsetae. The pronotum is transverse, nearly flat, and longitudinally canaliculate, with the base deeply notched and forming pronounced tubercles at the lateral angles. The elytra are reduced, overlapping at the base, and dehiscent, partially covering the first few abdominal tergites. Legs are weak and slightly hairy. Males show enlarged tarsal segments with pads of black bristles, absent in females. The abdomen is voluminous, with sexually dimorphic terminal structures. The genitalia are distinct and include curved parameres and well-separated penis hooks.
Body length: 11 - 32 mm
Peak activity: (February) March - May
Remarks: Physomeloe corallifer is an Iberian endemic, widely distributed in Portugal and central and western Spain, with a few apparently isolated populations also in eastern and southern Spain. Physomeloe corallifer is a diurnal species, inhabiting the meseta, plateaus and mountainous areas of the Iberian Peninsula, at an altitude of approximately 700–1400 m, mainly in steppe or Mediterranean mountain habitats.
