Tetranychus ludeni Zacher, 1913

Aedeagus bends dorsad; aedeagal knob without a posterior projection, anterior projection small and acuminate; knob and shaft axis parallel (Figure 5 C). Proximal pair of duplex setae on tarsus I almost in a straight line with tactile setae.

Specimens examined: Many individuals available collected on Physalis heterophylla (Solanaceae) growing in a flower bed in Kangemi, Nairobi (S01°15.984'; E036°45.810') and on Bidens pilosa (Asteraceae) in Runda (S01°13.470'; E036°48.050') Nairobi.

Remark: This species is widespread world-wide and occurs on a wide range of host plants. It was first described on Cucurbita sp. and Salvia splendens from Germany (Zacher, 1913). Its first report in Kenya was on Chrysanthemum sp. ( Asteraceae) from an unknown locality (Jeppson et al., 1975).
