Remarks. Otostigmus limbatus is the most widely distributed Brazilian representative of the genus. It extends north through the states of Pará and Mato Grosso to the states of Pernambuco, Bahia, Minas Gerais, Espírito Santo down towards southern Brazil to Santa Catarina ( Figure 40 ). It is one of the easiest Brazilian Otostigmus to identify, alive or in collections. Its color is characteristic with the cephalic plate, first and ultimate pedal segments reddish-yellow and trunk light brown or yellow gray; the lateral edges of tergites are black; two blackish lines along the paramedian sutures. It can also be easily identified by the first four glabrous articles of antennae, complete paramedian sutures in almost all sternites and absence of tarsal spurs on almost all legs.

Bücherl (1946b) described O. limbatus diminutus Bücherl, 1946 from São Paulo, Brazil. This subspecies should differ from the nominal species by the number of basal articles glabrous (two to four or five), presence of complete paramedian sutures in sternites 5 to 20 and tarsal spurs lacking from leg 2 or 3. Because of this, Bücherl (1974) elevated O. limbatus diminutus to the species level. The types of both nominal taxa and several additional specimens were examined. The number of basal glabrous articles varies from 2 to 5 in both nominal taxa, the complete paramedian sutures in the sternites of the type of O. limbatus starting from sternite 5 as in O. diminutus and also the tarsal spurs are lacking on legs 2 (or 3) to 20 in both species, therefore O. diminutus is considered here a junior subjective synonym of O. limbatus .
