New combination. [ Figs 10 f–m] Asphondylia bursaria Felt, 1927b: 387 . Material examined. Syntypes , 5 males , 9 females and pupa(e) ( NYSM #a3393), on two slides, reared from stem galls on Symplocos fasciculata Zoll. collected at Mt Gede , Cibodas , near Bogor , Java , Indonesia , altitude 1500 m , ii-1925 . The adults are on two slides, one with 2 males and 5 females , the other, 3 males and 4 females , all uncleared and mounted laterally. No pupa appears on either slide so is evidently lost . Description. Male . Length 2 mm ( Felt 1927b ). Wing length 2.5 mm , width 1.2 mm (1.2–1.3). Head. Antenna with scape 1.5x longer than wide, 2x length pedicel; pedicel wider than long; flagellomeres 12 in number, evenly cylindrical, 3x longer than wide, slightly constricted at basal third [ Fig. 10i ]; circumfila comprising four wavy longitudinal bands connected by high loops anteriorly and low loops posteriorly. Palpus 2-segmented, second segment slightly shorter and narrower than first [ Fig. 10j ]. Wing with C ending near wing apex, R 1 ending slightly anteriorly of wing midlength. Tarsal claws simple, narrow, bent at distal third, empodia reaching bend in claws [ Fig. 10g ]; pulvilli minute. Apicoventral spur on first tarsomere robust, short, bent at right angle [ Fig. 10h ]. Gonostylus with two separate teeth, one more pointed than the other [ Fig. 10f ]. Female . Length 2.5 mm ( Felt 1927b ). Wing length 2.6 mm (2.5–2.7), width 1.4 mm (1.3–1.4). Flagellomeres 10–12 progressively shortened [ Fig. 10m ], circumfila sparse, comprising three wavy longitudinal bands connected by low loops at either end. Needle-like protrusible part of ovipositor about 2x longer than seventh sternite [ Figs 10k, l ]. Pupa , larva unknown. Remarks . Known only from the adults, B. orientalis could fit in either Bruggmanniella or Pseudasphondylia , genera defined on the basis of larval and pupal characters ( Gagné 1994 ; Elsayed, pers. comm.). We tentatively combine this species with the older generic name, Bruggmanniella . Biology. Bruggmanniella bursaria induces a stem gall on Symplocos fasciculata (Symplocaceae) , described and illustrated by DvLR & DvL (1926, gall No. 1216 Fig. 877 [ Fig. 10n ]). On young stems, irregular outgrowths develop that are about 3 mm across, each containing an oval larval chamber lined with fungal tissue. The galls are often arranged gregariously, giving an appearance of a complex gall 50–100 mm in length. Affected stems are often bent or curved. Pupation takes place in the gall. Geographical distribution . The currently known range comprises three localities in the Bogor area, Java (DvLR & DvL 1926): Mt Gede, Cibodas, altitude 1500 m , collected by M. E. Jacobson ii-1916 , ix-1918 , xii-1918 and ii-1925 ; Mt Panisian, near Bogor, altitude 700 m , xii-1923 ; Mt Salak, Gunung Bunder, altitude 1000 m , viii- 1925 .
