Calophya andina sp. n.

(®gures 3, 11)

D escription . Adult. Coloration. Head and body dark brown with irregular lighter pattern. Antennal segments 1, 2, 9 and 10 almost black, 3±8 ochreous or light greyish brown. Legs ochreous, apical tarsal segments brown. Forewings transparent, veins ochreous to brown. Young specimens with more extended yellow or green coloration.

Structure. Anterior portion of vertex covered in short setae which are about as long as distance between them; genal processes moderately long, slender, contiguous in the middle. Forewings (®gure 3A) oval, widest in apical third, evenly, broadly rounded apically; surface spinules, apart from base of cell cu 2, absent. Genitalia as in ®gure 3B±K. Male subgenital plate short; proctiger massive; paramere long, truncate apically; distal portion of aedeagus long with straight, long shaft and short apical dilatation. Dorsal margin of female proctiger roundly excavate; subgenital plate pointed apically.

Fifth instar larva (®gure 11). Body yellowish with ochreous sclerites. Eyes red. Tips of antennae dark (from material in alcohol). Anterior margin of head weakly concavely rounded, not cleft in the middle. Antenna straight, conical, without sectasetae. Legs with claws. Anterior margin of humeral lobes level with posterior eye margin. Abdominal dorsum with median row of horns. Caudal plate ratio 0.53. Circumanal ring circular. Head margin without setae; wing bud margins with unspecialized setae only; abdominal margin with lanceolate setae.

Host plant, gall and biology. Schinus montanus . Nipple gall on the leaf blade along the mid-vein or near the base. On one side the gall is forming a conical nipple with some hairs around the opening channel. On the other leaf face the gall forms a rounded swelling. On emergence of the adult the central part widens and the hairs form a crown around the opening. The gall has one chamber comprising a single larva. A single female was collected on S. polygamus , which may be accidental.

D istribution . Argentina (RõÂo Negro), Chile (Regions IV and Metropolitana).
