This species belongs to the plumiferspecies group as setae J2and R1are present ( Chant and McMurtry 1994). It is widely distributed in sub-Saharan Africa, Madagascar( Demite et al.2019), in La Réunion( Quilici et al., 2000; Demite et al.2019) and recently from one island of the ComorosArchipelago, Grande Comore( Kreiter et al.2018b). The biology of this species remains totally unknown. If all details of collections were provided in the previous paper concerning La Réunion( Quilici et al.2000), measurements of specimens collected and identified were not published. Measurements of specimens collected during this study are provided in table 30.

Remarks: measurements of characters of the two females of P. ambafrom La Réunion( Table 30) compared to those of specimens from neighbouring countries show a slight variation of dimensions depending of the geographical origin. Measurements of characters of the two collected females are close from those of specimens from South Africa(Moraes et al. 1989), especially setae j1, J2, z3, Z5, S6, r3, JV5and spermathecal width. Setae j3and z3are smaller and macrosetae of leg IV are longer in specimens from La Réunioncompared to specimens from ComorosArchipelago but numbers of specimens (2 and 1, respectively) are very low in both cases.
