Description. Adult. Loginova (1976).
Fifth-instar immature (based on material from Madeira). Colouration of slide-mounted material. Sclerites pale yellow, membranes colourless. Apical half of antennal segment 7 dark brown.
Structure. Conforming to the generic description of Ossiannilsson (1992). Body 1.4 times as long as wide. Antenna 0.5 times as long as forewing pad; segments 4–6 together 1.1 times as long as segment 7; capitate setae on flagellum each about as long as diameter of corresponding segment. Forewing pad with 10–11 long and 6–8 short or half-long marginal capitate setae and a few scattered short dorsal capitate setae; hindwing pad with 2 long capitate setae. Caudal plate 0.6 times as long as wide; lacking marginal sectasetae, with 29 long and 11 half-long dorsal and marginal capitate setae (one side only), long dorsal and long marginal setae of subequal length; longest marginal seta about as long as antennal segment 7. Outer circumanal ring small, its length along longitudinal body axis about equal to its distance from caudal margin of caudal plate; subcircular, complete (closed) anteriorly; consisting of a single row of narrowly oval pores.
Measurements (in mm) (1 individual). Body length 1.8; length of forewing pad 0.66.
Distribution CI. Tenerife (Loginova 1976), La Palma (Domingo-Quero et al. 2003). La Gomera, Gran Canaria (new records).
Host plant CI. A single ♀ was collected on Salix canariensis (Salicaceae). This Macaronesian endemic tree is a likely host of Cacopsylla atlantica previously reported from the Madeira Islands.
Comments. In the key to immatures by Ossiannilsson (1992), Cacopsylla atlantica keys out with C. moscovita (Andrianova, 1948), C. palmeni (L̂w, 1882) and C. propinqua (Schaefer, 1949), from which it differs in the absence of long capitate setae on the forewing pad. From C. palmeni it also differs in the generally weakly sclerotised sclerites and the anteriorly closed outer circumanal ring.
