Body length, 4.3-6.4 mm, 1.8-2.0 mm maximum width (n = 32). Head ( Figs. 4A, 4B View Figure 4 ). Antennal horns, 0.02 mm, well developed, triangular, inner margin finely serrate, outer margin smooth.

Thorax: Prothoracic spiracle short, 0.12 mm length, setiform with an accessory structure in spiral format ( Fig. 4C View Figure 4 ). Wing reaching third abdominal segment and legs reaching fifth abdominal segment. Abdominal tergites 2-8 with two rows of strong spines in caudal area and small spines scattered in proximal area. Terminal segment with one row of hooked spines ( Fig. 4D View Figure 4 ). Pupation in gall.

Larva 3rd instar: Light cream. Body, 3.1 mm length, 1.6 maximum width (n = 1). Integument sclerotized, cephalic setae, 0.01 mm length. Thorax: Area around prothoracic spatula pigmented, spatula 0.3 mm length, four teeth anteriorly, middle tooth smaller than lateral teeth, with narrow shaft; one pair of setose inner lateral papillae and two pairs of setose outer lateral papillae ( Fig. 5A View Figure 5 ). Abdomen: Segments 1-8 covered by round plates with microspines dorsally and ventrally, spiracles short and sclerotized; terminal segment ( Fig. 5B View Figure 5 ), 0.03 mm length, 0.07 maximum width, round with a pair of short setose papillae; anus dorsal in cleft, flanked by elongated cells ( Fig. 5C View Figure 5 ).

Etymology: The specific name “ cipo ” is in apposition, referring to the type locality, Serra do Cipó.

Gall and biology ( Fig. 6 View Figure 6 ): Globoid stem and petiole swelling on Lessingianthus warmingianus (Baker) H. Rob. (Asteraceae) . Galls are bare, monothalamous, unilocular even when closely approximated to one another. The interior of larval chamber is lined with a fungal mycelium, as described for A. glomeratae and A. moehni in Gagné et al. (2001). Pupation in gall. The adults emerged through an escape hole dug with the antennal horns of the pupa.

Holotype: Male: Brazil, Minas Gerais: Santana do Riacho, Pedra do Elefante trail in Serra do Cipó (S19°17.468 ”; W43°32.564 ”, 1,237 m altitude), collected 14.xi.2002; emerged 20.xi.2002, collected and reared by M. V. Urso-Guimarães from stem and petiole swellings on Lessingianthus warmingianus (Baker) H. Rob.(Asteraceae) . Deposited in slides as mounted specimen at the MZSP.

Paratypes: 57 specimens,same data as holotype, except for: 1 male, 1 female, 1 pupal exuviae, 1 larva ; in alcohol: same collect date of holotype, except for: 1 male, 2 females, 2 pupae, 4 exuviae emerged in 18.xi.2002; 1 male, 1 female, 10 pupae, 2 exuviae emerged in 19.xi.2002; 4 males, 4 females, 1 pupa, 8 exuviae, 2 larvae emerged in 21.xi.2002; 1 male, 1 exuvia emerged in 25.xi.2002; 1 male, 1 exuvia emerged in 26.xi.2002; and 3 males, 2 females, 2 exuviae emerged in 03.xii.2002 (deposited in MZSP) .

Remarks: Asphondylia cipo sp. nov. can be easily differentiated from any other species of the genus by the following set of characters: the great body length; needle part of ovipositor 1.6 mm length, 2.3 times longer than sternite 7; upper frontal horn simple, lower frontal horn trilobed; prothoracic spiracle setiform with an accessory structure in spiral format; four-toothed prothoracic spatula of larva, the inner pair tiny and widely separated; one pair of discrete terminal papillae; galls on stem and petiole of Lessingianthus warmingianus .

Of the 16 species Asphondylia inducing galls on Asteraceae whose larvae are known, only A. ajallai , A. serrata , A. ulei , A. zacatechichi , and A. cipo sp. nov. have spatula with inner teeth much less than ½ the size of the outer with the inner incision flat and wide ( Fig. 7F View Figure 7 ), however,the distance between the inner teeth is much larger in A. cipo sp. nov. than in the other known species; from these, only A. serrata and A. cipo sp. nov. share one inner and two outer lateral papillae, A. ajallai and A. ulei have two inner and two outer lateral papillae, and A. zacatechichi has 3inner and 2 outer lateral papillae. Asphondylia cipo sp. nov. differ of A. serrata by the shape of antennal horn, triangular in the former, rectangular in the later in pupa; and in females, the needle part of ovipositor is 2.3 times longer than sternite 7 in the former and 1.87 in the later. The morphological evidence discussed above indicates that this species is distinct from all other species of Asphondylia inducing galls on Asteraceae described previously.
