Phylloicus yolandae, new species

Figs. 104, 116

Phylloicus yolandae is one of the prettiest and most unusual species of Phylloicus . With its partially clear forewings and dramatic coloration (Fig. 116), this species resembles clearwinged moth species found in the region. The male genitalia are recognized by the cordate tergum X and the digitate preanal appendage.

Adult. Forewing length 8.1 mm, n = 1.

Head dark brown or black. Maxillary palps dark brown or black. Antenna twice forewing length; dark brown, with narrow patches of pale sensilla on anteromesal surface of each flagellomere. Dorsal pterothorax dark brown or black; ventrolateral thorax dark brown. Legs dark brown. Metathoracic leg of male without posterior fringe. Tibial spur formula 2,4,4. Forewing flat; dark brown, or black; with two transverse bands; proximal band ivory, reaching posterior wing margin, at least 1/2 width of wing, interrupted by clear patch (Fig. 116); distal band ivory, not reaching either wing margin, 1/2 width of wing or less; with single basal stripe, ivory; large clear patch in center of wing (Fig. 116).

Male. Preterminalic abdominal terga without anteromesal notches. Corematic structures absent, terga III­V unmodified, without membranous lobes or sclerotized processes. Sternum VIII similar to anterior sterna, sternum IX not elongate. Tergum IX without mesal ridge; posterior margin notched (Fig. 104B); lateral ridge present; dorsal pleural setae approximately 8, ventral pleural setae approximately 2 (Fig. 104A); sternum IX without mesolateral ridges; sternum IX (Fig. 104C). Preanal appendage shorter than tergum X, but greater than 2/3 length, narrowly elliptic, setae long, but not filamentous or longer than appendage (Fig. 104A, B). Tergum X without basal lobes; basodorsal process absent; basolateral processes absent; apex, in lateral view, acute, in dorsal view, notched, notch deep and round; setose basodorsally; broad basally, constricted at mid­length (Fig. 104A, B). Harpago sharply tapered; peglike setae few, apical (Fig. 104A, C). Phallic endotheca with paired apicolateral lobes, apicolateral lobes large and rounded; phallotremal sclerites small, longest dimension 1/2 diameter of phallobase; dorsal sclerite ovoid, in dorsal view horseshoe­shaped (Fig. 104D, E).
