* Otostigmus pococki Kraepelin, 1903

Type locality. Haut Carsevenne, French Guyana.

Brazilian published records. Pará. Belém ( Schileyko, 2002).

New records. None.

Remarks. This species is common in Venezuela and Peru, and has been recorded once from Belém, in Brazil. Otostigmus pococki was described from Haut Carsevenne, French Guyana, that nowadays belongs to the state of Amapá in Brazil ( Figure 41 ). The male of Otostigmus pococki resembles the males of O. clavifer Chamberlin, 1921 and O. brunneus Chamberlin, 1921 in the presence of a digitiform appendix which emerges from the base in dorsomedian position in the prefemur of the ultimate pair of legs and paramedian sutures in sternites. However, O. pococki differs from them in having keels on tergites 12 to 20 (median longitudinal keel and longitudinal keels on each side of the paramedian sutures), three incomplete keels on tergite 21, 17 antennal articles and the lack of a tuft of hairs at the tip of the digitiform appendix. In O. clavifer and O. brunneus there are no keels on the tergites, the dorsal integument is smooth, there are 20 antennal articles and there is a tuft of hairs at the tip of the digitiform process in a median or mesal position ( Chamberlin, 1921).
