Bastin) ( MUSA , 70% ethanol) . Description. Adult. Loginova (1976) . Fifth-instar immature. Colouration from slide-mounted specimen. Sclerites, legs and wing pads dark brown. Antenna light brown, with segments 4–8 apically and segments 9 and 10 entirely dark brown or black. Membranes colourless. Structure . Body ( Fig. 198 ) flattened, oval, 1.2 times as long as wide; irregularly covered with small lanceolate setae. Antenna 0.9 times as long as forewing pad, 10 segmented with a single rhinarium on each of segments 4, 6, 8 and 9; all segments each with 1 or 2 microscopic lanceolate setae, and segments 3–9 each with a very long fine seta. Thoracic tergites moderately large. Legs relatively long; both claws developed and of equal size; tarsal arolium small, fan-shaped, bearing unguitractor and petiole of about the same length as claws and relatively wide compared to small arolium. Forewing pad large and lacking humeral lobe, oblong oval, outer margin weakly convex, inner margin weakly concave, apex irregularly rounded. Caudal plate large, 0.8 times as long as wide, slightly truncate apically and bearing a marginal tubercle on either side. Anus in terminal position; circumanal ring large, convoluted, spreading dorsally and ventrally; outer ring consisting of 1 (medially) to 4 (laterally) rows of almost circular pores. Measurements (in mm) (1 individual). Body length 1.5; length of forewing pad 0.76. Distribution CI. Gran Canaria ( Loginova 1976 ). Tenerife ( new record ). Host plant CI. Olea cerasiformis , O. europaea (Oleaceae) . Biology. The immatures are free-living and produce a white waxy secretion under which they develop ( Fig. 240 ).
