Phyllocnistis longipalpa Davis & Wagner

Adult (Fig. 2C): Length of forewing: 2.3 to 2.6 mm. Head: Frons shiny white, smooth with subtle faint orange tints over vertex. Flagellomeres with faint orange luster above. Labial palpus white, long, 1.2? height of head, slightly upcurved; basal segment subequal to segments 2 + 3. Thorax: Patagia and tegulae with subtle, silvery, stramineous to orange tints. Longitudinal fascia joining transverse fascia, edged with black scales above and below, with those below more consistently present distad. Transverse fascia leaves costal margin at 45° angle; proximal edge of transverse fascia where it leaves the inner margin vague, composed of 2-3 rows of dark scales. Second costal fascia fusing with transverse fascia distally. Apical spot poorly differentiated; likewise apical strigulae vague and poorly developed. Black fringe scales about tornus little broadened and not conspicuously elevated above plane of wing. Legs essentially silvery white and unmarked with exception of faint orange luster to dorsal and outer surfaces of foretibiae and foretarsi; distal tarsomeres sometimes modestly darkened. Abdomen: Silvery white and unmarked. Male Genitalia (Figs 18 A-C): Similar to P. hyperpersea and subpersea except apex of valva not evenly rounded, instead more oblique and extended dorsad; total length of valva ~ 2.0? length of vinculum; basal apodemes of valva less divergent than in other species, with ventral apodeme strongly curved (Fig. 18B). Aedeagus ~ 0.65? length of valva. Female Genitalia (Figs 18 D-E): Similar to P. perseafolia, with ductus bursae long, ~ 6.5? length of papillae anales and terminating near caudal end of corpus bursae; corpus bursae elongate-ovoid, enlarged, ~ 0.6? length of elongate ductus bursae; ductus seminalis ~ 2.4? length of corpus bursae. Larva and pupa: Not examined. Larval Mine: Similar to that described for P. subpersea. A long, slender, serpentine gallery, containing a dark, narrow, median frass trail, present on the underside of the leaf, with pupation occurring in a slightly enlarged, elliptical chamber at the mine terminus along the leaf edge.
