Material examined.

2♂, 2♀: (Mamaev collection: slide no. B1-251363 & 251364), galls collected from Aster sp. in Kedrovaja Pad reserve, Russian Far East on 28.viii.1964. 4 larvae: galls collected from A. tataricus in Smolyaninovo, Primorsky Territory, Russian Far East on 13.ix.2002, M. Tokuda leg. 6 larvae: galls collected from A. scaber in Smolyaninovo, Primorsky Territory, Russian Far East on 13.ix.2002, M. Tokuda leg.

Description.

Head: Compound eyes with rounded facets; facets on the vertex and eye bridge unobservable. Palpus: first segment ca 34.5 μm, second 1.8 times as long as the first, third 1.2 as long as the second, fourth 1.1 as long as the third.

Thorax: Wing length 1.93 mm (n = 1) in female, 1.55-2.02 mm (n = 2) in male. Anepimeral setae 14-15 (n = 3); mesanepisternum scales 17-23 (n = 7); lateral scutum setae 23-29 (n = 4). Lengths of leg segments as in Suppl. material 1: Table S4.

Female abdomen: Ovipositor: protrusible needle-like portion about 5.7 times as long as sternite VII; cerci divided medially, with sclerotized margins and few setae (Fig. 89).

Male abdomen: Terminalia (Fig. 90): Gonocoxite with pointed apical lobe extending beyond gonostylus. Gonocoxite length about 3.5 times as long as gonostylus. Gonostylus without setae ventrally and dorsally.

Mature larva: Sternal spatula with posterior portion about 3.3 times as wide as the base of the anterior free portion (Fig. 91). Abdominal segment VIII with three dorsal lobes, the outer two each with 1 setose dorsal papilla (Fig. 92). Anus with branched opening, and 4 asetose anal papillae (Fig. 93).

Pupa: Prothoracic spiracle about 220 μm long (n = 1).

Distribution.

Russian Far East ( Kovalev 1964; Tokuda et al. 2003).

Remarks.

Although Kovalev (1964) mentioned that S. asteris is closest to S. doellingeriae , Tokuda et al. (2003) showed that they are distinguishable by the number of lateral papillae, terminal papillae, and the shape of anal opening.
