Comments. This species is placed in Oculogaster based on the original description, according to which it is similar to P. ( O.) cylindroculum and its «stigma normally with a single crossvein» ( Gillies 1997: 248). Other characters of Oculogaster (the setation of labrum, the apical setae of femur, the viviparity) are not described for this species. In a previous paper ( Kluge 2016), I suggested silvicola [ Procloeon ] to be treated as a geographical form or subspecies of P. ( O.) cylindroculum . But taking into account the existence of such distinct sympatric species as P. ( O.) barnardi sp. n. and P. ( O.) niger sp. n. (see below), species status of P. ( O.) silvicola should be assumed as well.

Comparison. According to the original description, winged male and female stages of P. ( O.) silvicola differ from P. cylindroculum by more extensive hypodermal marking on abdominal tergum IV, which in P. ( O.) silvicola represents «a complete band of pigment across the posterior part of tergum IV» ( Gillies 1997: figs 3, 5), being in male «a broad red band across posterior 2/5 of segment»; in contrast to this, in P. ( O.) cylindroculum markings of abdominal tergum IV in male are either small or absent, and in the female they are not connected medially. In this respect, P. ( O.) silvicola is similar to P. ( O.) barnardi sp. n., but differs from it by the absence of unpaired median stripes, which in P. ( O.) barnardi sp. n. are developed at least on tergum IV of the male and female.

Distribution. West Africa ( Gillies 1997).
