Interpretive Summary: Stinkbugs include serious agricultural pests as well as beneficial species. Accurate identification is necessary for rational pest management decisions. The present article describes a new genus and species and details the key characteristics separating it from previously known species. The new genus is assignable to the tribe Ochlerini, a tropical group that includes vectors of microbes that cause decline in species of palm trees.

Technical Abstract: In addition to the carinate metasternum, in Cromata the labrum equals the length of the first labial segment, whereas in Pseudocromata the labrum equals the length of the first two labial segments. The males of Pseudocromata do not have the dorsal process extending from the 7th abdominal tergite found in Cromata. The male genitalia of Pseudocromata bears no resemblance to those of Cromata. Previous reports had Cromata aligned with Barola and Catulona because the lateral margin of the evaporatorium is straight in those genera. In Pseudocromata the lateral margin is curved.
