Tainarys maculipectus sp. n.

(®gures 25A±E, 28)

Description. Adult. Coloration. Head whitish to yellowish with reddish to brownish small dots. Thoracic dorsum black with some white lateral dots and reddish platellae, in younger specimens with brown spots and more expanded red colour. Antennae yellow, segments 9 and 10 black, apices of segments 4 and 6 brown. Clypeus black. Thorax laterally and ventrally black with ochreous patches and white and red dots. Legs yellow, pro and mesocoxae blackish. Forewings yellow base whitish, a single brown spot at the apex of vein Cu 1 b. Hindwings whitish. Abdomen including genitalia yellow.

Structure. Head about as wide as thorax, in pro®le, inclined in a 45ss angle to longitudinal body axis. Vertex ¯at anteriorly smoothly passing into genae, median suture fully developed. Compound eyes hemispherical. Antennae 10-segmented with each a subapical rhinarium on segments 4, 6, 8 and 9Ë shorter terminal seta about as long as segment 10, longer seta about 1.5 times as long. Frons short wider than long. Clypeus pear-shaped. Pronotum transverse, short, very slightly curved backwards at the sides; propleurites partially hidden by eyes, rectangular, both dorsal branches of suture developed, epimeron larger than episternum. Mesopraescutum short, transverse, mesoscutum ¯at; meso and metascutellum forming distinctly raised tubercles. Legs relatively slender, pro and mesofemora slightly thickened. Metacoxae bearing a ¯at, tubercular meracanthus and a conical membraneous process on the trochanteral cavity. Forewings (®gure 25A) subrhomboidal, vein C +Sc straight or weakly concave, slightly widened, costal break developed, membrane transversely rugose, semi-transparent. Genitalia as in ®gure 25B±E.

Fifth instar larva (®gure 28). Body brown, membranes light. Dorsal sclerites of head and thorax light brown; wing buds, abdominal dorsal sclerites and caudal plate dark brown. Antenna ochreous with apex dark brown to black. Body outline broadly oval. Antennae 8-segmented with one rhinarium on each of segments 3 and 5, and two on segment 7. Thoracic tergites small. Forewing buds moderately large, without humeral lobes. Truncate lanceolate setae present on head and thorax dorsally, and on wing buds and abdomen dorsally and laterally; lanceolate setae denser and coarser than in T. acuticauda . Legs relatively large and slender with fused tibiotarsus, claws absent. Caudal plate pointedly angular apically; dorsal lanceolate setae arranged in transverse rows. Anus ventral, circumanal ring small, consisting of one row of pores which are elongate.

Host plants, gall and biology. Schinus polygamus (Cav.) Cabrera. Inducing irregular leaf roll galls.
