Descriptive Notes. Dorsum dark brownish-black to bronzy. Pronotum with base densely punctulate, often with fine rugulae. Elytra with seriate punctures small, with microsculpture granulate, isodiametric. Metatarsi dorsally with dense, long pubescence. Dimorphism + ♂ 1 — ♀ 2. Median lobe with dorsoapical plate slender, strongly hooked dorsad. Endophallus with 2–4 long slender spines; lamina prominent. ABL 7.2–8.0 mm.

Range. USA: AL*, FL, MS; West Indies; Nicaragua; Argentina; Bolivia *; Brazil; Colombia, Peru; Venezuela.

Remarks. The known geographical range of S. discopunctatus is disjunct. It includes southeastern USA, several countries in South America, and much of the West Indies, but is apparently not present in Mexico and Central America. Selenophorus yucatanus Putzeys (1878a: 24) , of the Yucatan Peninsula (type area) and the Lesser Antilles ( Shpeley et al. 2017), is similar in appearance and potentially sympatric. As members of the discopunctatus species group, both species have the basal one third of the pronotum densely punctate which in S. yucatanus includes coarser longitudinal rugae that are most distinct posteriomedially. Additionally, S. yucatanus has larger (foveate) seriate punctures, greater average ABL in the Mexican populations (at least 8 mm), and the median lobe is with endophallus unarmed and the apex is without a prominent hook ( Shpeley et al. 2017).
