Other characters as in male.
Pupa ( Fig. 8A View Figure 8 ): Color: brownish. Body length: 4.50-4.90 mm (N = 2). Head ( Fig.8B View Figure 8 ): dorsal plate 0.06 mm long, 0.09 mm wide (n = 1); face with lateral projection; antennal horn triangular, 0.38 mm long (N = 2), apical part 1.37 X length of basal part, inner margin serrated; apical seta 0.05 mm long (N = 2), 0.5 X wide of antennal flagellomere; upper facial horn simple, 0.03 mm long (N = 2), triangular, as long a width of basal flagellomeres; lower facial horn tridentate, 0.01 mm long (N = 2), 0.2 X length of antennal horn,teeth triangular, not aligned,lateral teeth conspicuously above mesal tooth triangular; A. mineira ), ratio between 6 th and 7 th sternite length in females (1.75-1.90× in A.gaucha and 2.2-2.5× in A.mineira ), shape of antennal horns in pupae (more pointed apically in gaucha than in A. mineira ), length of prothoracic spiracle (about 2 times longer in A. mineira than in A. gaucha ), and number of dorsal spines in the posterior row of 2 nd abdominal segment (more numerous in A. gaucha than in A. mineira ).
Möhn, 1959 described Asphondylia ajallai from El Salvador.This species induces bud galls on Lepidaploa canescens (Kunth) H. Rob. (recorded as Vernonia canescens Kunth. ), Vernonanthura patens (Kunth) H. Rob. (recorded as Vernonia patens Kunth. ) and Vernonia sp. (Asteraceae) . It is known from the female and larva. Only females of Asphondylia gaucha and A. ajallai can be compared to each other.They differ from it mainly in the length of empodium (longer in A. gaucha than in A. ajallai ) and shape of tarsal claws (more curve in A. gaucha than in A. ajallai ) ( Fig. 9B View Figure 9 ). Larvae and females of Asphondylia mineira can be compared with those of A. ajallai . The spatula of A. mineira has longer mesal teeth and wider anchor base than in A. ajallai ( Fig. 9C View Figure 9 ). Furthermore, A. mineira has three lateral papillae on each side of the spatula, while A. ajallai has four ( Fig. 9C View Figure 9 ). Females of both species have empodia subequal in length. Nevertheless, the tarsal claws of A. mineira are more curve than those of A.ajallai .
