* Otostigmus goeldii Brölemann, 1898

Type locality. Brölemann (1898) did not specify the type locality precisely, only cited San Steban, Venezuela and state of Pará, Brazil, and are hosted in the myriapodological collection of the Muséum National d´Histoire Naturelle, in Paris, under the number ( MNHN CDLXXXIII) and ( MNHN CCCV) respectively. In the original description Brölemann (1898) commented about the possibility of O. goeldii being a juvenile of O. scabricauda , however he found another specimen from Venezuela that resembles the specimen from Brazil. As he did not define clearly which the two specimens was the type, the specimen ( MNHN CCCV) from Pará, Brazil is designed as lectotype for O. goeldii .

Remarks. Its small body size, the presence of a very short digitiform appendix on the prefemora of the ultimate legs and its rare presence in collections led some authors to believe that O. goeldii could be the juvenile of a species of Otostigmus with digitiform appendix. Attems (1928) described O. fossulatus from San José, Costa Rica which closely resembles O. goeldii . Body size, tooth plates, complete paramedian sutures and margination of the tergites, sternites without sutures, but with depressions, and ultimate pair of legs are in accordance between O. goeldii and O. fossulatus . The tooth plates have 4+4 teeth; complete paramedian sutures are present on tergites 3 (or 4 or 5) to 20 and the margination on tergites 7 to 21, alongside the prefemur of the ultimate pair of legs of males there is a very short digitiform appendix, without tuft of hairs at the tip. This appendix is at most one fourth the length of the prefemur and arises from the base of the prefemur in a dorsomedial position. The small body size and the presence of one tarsal spur on leg pair 1 (or 2) to 9 are also characters shared by O. goeldii and O. fossulatus . O. fossulatus is here considered a junior synonym of O. goeldii . Otostigmus goeldii is now known from Costa Rica (as O. fossulatus ), in Venezuela and north of Brazil. It is recorded for the first time from northeastern Brazil ( Figure 39 ).
