Summary: | Subfamily Silphinae Necrodes surinamensis (Fabricius, 1775) Figs. 5, 19, 32, 45 Silpha surinamensis Fabricius, 1775: 72. Diagnosis. Body length 20–25 mm, broadly subparallel, dark brownish to black, elytra with small subapical reddish maculae. Head with large eyes, without short row of long erect hairs behind each eye. Pronotum orbicular, widest towards middle; disc without pubescence. Elytra with apices conjointly subtrunctate to projected medially; disc tricostate, intervals smooth and finely granulose; epipleuron oblique, wider at base than apex, coloration not differing from remainder of body. Hind femur of male swollen, with one or two spines. Range. Newfoundland south to Florida, west to British Columbia, Oregon and Texas (Anderson & Peck 1985, Peck & Kaulbars 1987); possibly in northern Mexico (Peck & Anderson 1985). The stated type locality, “ America meridionali ”, and the species-group name suggests that this species occurs in South America, but this was discounted by Peck and Anderson (1985) who suggest that it ranges no further south than possibly the extreme northern areas of Mexico along the Texas border. Texas distribution. See Fig. 45. This species is widespread in the Austroriparian and Texan biotic provinces of eastern Texas, with scattered records from the Tamaulipan, Balconian, Kansan, and Chihuahuan provinces. It occurs in the following Texas vegetational areas: pineywoods, gulf prairies and marshes, post oak savannah, blackland prairies, cross timbers and prairies, south Texas plains, Edwards Plateau, rolling plains, high plains, and trans-Pecos.
