Similar to other Spharagemon, but differs in smaller size than most of those, smalish head and nearly flat top of pronotum with median ridge low and cut twice instead of (usually) once. Also, other species of Spharagemon have the inner side of the dark band on the hind wing curved, and it is usually nearly straight with the band not curving as far around the margin in S. campestris. Most similar to Trimerotropis modesta, differing primarily in coloration and favoring more open grassland habitats. T. modesta is generally not as speckled; usually has more sharply defined dark bands crossing tegmina, not as irregular or broken, often narrower, and with front band more angled in orientation. Hind femur has inside usually mostly black with yellow cross bands; in S. campestris) usually orange, sometimes yellow, often but not always with dark markings. Hind wing with tip most often at least somewhat clouded dark in T. modesta, clear in S. campestris. T. modesta favors gravelly grassland and open woodland habitats, often on sloping ground, in mountains mostly south of the distribution of S. campestris. Other similar related Trimerotropis species include T. maritima, T. latifasciata, T. melanoptera, etc., which all differ in usually larger size, longer wings, details of coloration (wings, hind legs, etc.), and so on. In early literature, there was much confusion between various species of Trimerotropis and Spharagemon with red hind tibiae, and older records for several species are often questionable; many are definitely based on misidentified specimens. This species was often involved. |
