Description. Adult. Coloration. Head and thorax ochreous dorsally with reddish or brown pattern, ventrally dark brown. Apices of genal processes and antennal tips dark brown. Legs ochreous, apical tarsal segments dark brown. Forewings transparent, veins brown. Abdomen dark brown, intersegmental membrane light.

Structure. Anterior portion of vertex covered in short setae which are about as long as distance between them; genal processes long, slender, separated in the middle. Forewings (®gure 6A) oval, evenly, broadly rounded apically; surface spinules, apart from base, absent. Genitalia as in ®gure 6B±E. Male subgenital plate short; proctiger slender; paramere stout; distal portion of aedeagus long with weakly curved shaft and short, slightly elongate apical dilatation. Dorsal margin of female proctiger roundly excavate; subgenital plate subacute apically.

Measurements in mm (2, l 2 m). HW 0.46±0.50; AL 0.44±0.53; WL 1.69±1.75; MP 0.17; PL 0.11±0.12; AA 0.13±0.14; FP 0.25±0.26; VL/GL 0.76±0.94; AL/F1 2.32±2.68; AL/HW 0.94±1.06; WL/HW 3.42±3.80; WL/WW 2.27±2.73; a/b 1.35±1.56; c/d 0.83±0.86; TL/HW 0.66±0.72; MP/HW 0.34±0.46; AB/AA 1.00±1.08; FP/HW 0.52±0.54; FP/SL 0.96±1.00; FP/CL 2.50±2.89; FP/FA 2.00±2.50.

Fifth instar larva (®gure 14). Straw-coloured, intersegmental membranes lighter. Eyes brown. Anterior margin of head weakly concavely rounded, forming two shallow lobes. Antennae straight, without sectasetae. Legs with claws. Anterior margin of humeral lobes level with posterior eye margin. Abdominal dorsum without horns. Caudal plate ratio 0.45. Circumanal ring oval. Head, wing bud and abdominal margins with sectasetae.

Host plant, gall and biology. Schinus fasciculatus . Forming conical galls situated at the leaf margins (Kie er and JoÈ rgensen, 1910; Burckhardt, pers. obs.). Kie er and JoÈrgensen (1910) and JoÈrgensen (1917) provide a description and illustrations of the gall.

Distribution. Argentina (Mendoza). Reported from the Cordillera of Mendoza (Kie er and JoÈ rgensen, 1910; JoÈ rgensen, 1917). The records from the Buenos Aires Region may concern another species (see comments).

Material examined. Argentina: 1 m, Mendoza Province, Mendoza Valley, Uspallata to Potrerillos , 1700 m, 30± 31.xii.1995, Schinus fasciculatus (D. Burckhardt) ; 2, l 5 m, same data but Potrerillos , 1500 m, 31.xii.1995; 2 larvae, many galls, same data but 1300 m, 17.i.1997; 1 larva, ex gall, same data but Villa Hodel , 7 km Cacheuta to Mendoza , 1100 m, 17.i.1997; 1, l same data but above Villa Vicencia , 50 km NW Mendoza , 1800±2200 m, 18.i.1997; 1, l 1 m, Mendoza, Zoological Garden, vii.1997 (S. Roig). Dry and slide mounted ( MHNG, NHMB) .

Comments. The records of C. gallifex from Argentina: Buenos Aires by Tavares (1915), Lizer (1943) and Lizer and Molle (1945) are questionnable. There are two females in the USNM from Lizer’ s material. They are not conspeci®c with specimens from Mendoza and may represent an undescribed species. Manganaro (1919) described a leaf gall on Schinus polygamus from La Plata which is probably produced by Lizer’s species.
