Head (Fig. 14a): eye facets circular, closely appressed; antennae:scape trapezoidal, setose, pedicel globoid, setose, flagellomeres cylindrical, with microtrichose node and glabrous neck, flagellomere node 6.5 times the length of neck; 1 st and 2 nd flagellomeres connate; circumfila wavy (Fig. 14b); frons with 26 setae (n=1); mouth parts: labrum long-attenuate; hypopharynx of the same shape of labrum, with long anteriorly directed lateral setulae; labella elongate-convex, with lateral and three mesal setae each; palpus: 1 st segment and, 2 nd segment ovoid, subequal in lenght, 3 rd segment cylindrical, about 1.5-2.25 times the length of 2 nd segment (n=3), all segments with setae and scales. Thorax:scutum with two dorsocentral rows of setae, setae more abundant anteriorly, two groups of lateral setae with scales intermixed; scutellum with scattered setae; anepimeron with several setae and scales; other pleura bare; wing (Fig. 14c) length (from arculus to apex): 1.70-2.25 mm (n=3); all legs broken. Abdomen (Fig. 14d): 1 st –7 th tergites sclerotized, rectangular with posterior row of setae, few lateral setae, scales scattered, no basal pair of trichoid sensilla; 8 th tergite with an indentation at distal margin in midlenght, bare; 2 nd –7 th sternites rectangular with posterior row of setae, numerous setae at midlength, lateral setae present, scales scattered, a basal pair of trichoid sensilla, 8 th sternite with a reentrance at basal margin, near midlength, with scattered setae and scales, and a basal pair of trichoid sensilla. Terminalia (Fig. 14e): gonocoxite hemispherical, setose, 2.6–3.0 times the length of gonostylus (n=2); gonostylus rectangular with scattered setae, cerci separate, riniform, setose; hypoproct bilobed, setose; aedeagus conical, gonocoxal lobes very short.   
 Pupa redescription (Fig. 15a). 3,0- 4.3 mm long (n=7). Integument brownish. Head: a pair of antennal papillae present, antennal horn triangular, short, with outer and inner margins smooth; apical seta 0.07-0.08mm long (n=5); upper facial horns conical, short; lower facial horns absent; two pairs of lower facial papillae: one pair with seta, the other bare; a triplet of papillae (two with setae and one bare) near base of each palpus; upper cephalic margin thickened laterally, face without lateral projection, head integument wrinkled just below antennal bases and around upper facial horns and below them. Thorax: prothoracic spiracle not projected (Fig. 15b), prothorax with three pairs of dorsal papillae and two pairs of lateral papillae, no lateral projection just below prothoracic spiracles. Abdomen: spiracles not elongated, 2 nd –8 th segments with dorsal spines near anterior margin, arranged only centrally (Fig. 15c), spines in the 2 nd segment rudimentary, shorter than those of 3 rd- 8 th segments, integument ventrally sculptured. Last segment with two rounded terminal projections in both sexes, far apart in female pupa and closely appressed in male pupa (Figs. 15d, e).   
 Larva description. 3.20 mm long (n=1), body elongate, cylindrical, tapered towards posterior end (Fig. 16a); integument rough (Fig. 16b). Prothoracic sternal spatula absent, sternal papillae setose; three setose lateral papillae on each side, four dorsal papillae setose from 1 st to 7 th abdominal segments. Terminal segment (Fig.16c) with 1/16 of the total length of larva, elongate and strongly tapered towards apex, with four setose papillae; anus cleft; integument rough dorsally, ventrally with rounded sculptures near anus and striated distally.   
Gall (Fig. 16d). On bud, globose, green or reddish, with trichomes, one-chambered.
