Length 25-33 mm. angulatum is characterized by very angular pronotum and deep striation of elytra, on which base was created Carabosoma subgenus, that later Jeannel included inside of Camedula.
The shape of pronotum and the sculpture of elytra vary quite regularly from the northern to the most southerly populations: the populations of Colombia and Venezuela, in particular, have relatively less angular pronotum, that is also more densely dotted, and more scaly intervals.
Based on these characteristics, Jeannel has dealt with these populations as one separate species (angulicolle Chaud. 1869). Vice versa, Gidaspow (1959: 252, 1963: 280) has considered conspecific, angulatum and angulicolle, as later confirmed by Erwin (1991: 26).
angulatum, thus interpreted, is present in Arizona and occasionally in California, Texas (Burgess & Collins, 1917: 75) and New Mexico (Gidaspow, 1959: 253). It is widespread in Mexico, and reappears in Central America. It has been found in many localities in Costa Rica (Erwin, 1991: 26), in Nicaragua (www.bio-nica.info/), and cited but without any precision from Guatemala and Honduras, (Erwin, 2007: 87). It is present in Colombia and, according to old citations, also in Venezuela (Breuning, 1928a: 103)

Notes: Winged, often attracted to light at night. It lives from lowlands up to an altitude of 1800m. In Nicaragua it has been reported feeding on the noctuid caterpillar Spatodoptera frugiperda. Active adults have been noted from May to November (Erwin, 2007: 86).
