Tetranychus lombardinii Baker & Pritchard, 1960


Tetranychus lombardinii Baker & Pritchard, 1960  

Aedeagus curves dorsad, forming a knob about one fourth to one fifth length of dorsal margin of shaft; knob and shaft axes almost parallel; posterior projection small and acute; anterior projection rounded ( Figure 5 View FIGURE 5 B) male empodium I with 2 proximoventral spurs and a minute mediodorsal spur; empodium II with 3 pairs of proximoventral hairs and a tiny mediodorsal spur; female striae between third (e 1) and fourth (f 1) pairs of dorsocentral setae longitudinal, a diamond-shaped figure formed between these setae; dorsal lobes narrow, triangular, mostly taller than broad and well separated at their bases; in some specimens ventral lobes weak or absent but usually low, semicircular, broad and extend from genital opening to near gnathosoma; lobes on prodorsum very broad and hardly more than an occasional incision of striae.

Specimens examined: Five males and several females collected on Morus   sp. ( Moraceae   ) from ICIPE compound, Nairobi (S01° 13.140 '; E036° 53.440 ').

Remark: This species has been reported from the Tropics, Australia and Oriental Indian regions. It has a wide host range and occurs as a pest of several agricultural crops ( Meyer, 1974). The first record of this species in Kenya was on Spinacia oleraceae   ( Amaranthaceae   ) from Ruiru, Thika district ( Baker and Pritchard, 1960). It appears uniformly red in colour in the field.
