Phylloicus maculatus
is distinguished by its large size, wing pattern, and by having short, singlelobed lateral coremata, without modifications of tergite IV (
Fig. 64F
). The wing pattern of this species is identical to that of
P. elegans
and
lituratus
. The female genitalia are indistinguishable from those of the latter two species.
Adult. Forewing length 13.415.
4 mm
, n = 31.
Head dark brown, setal warts very dark. Maxillary palps dark brown, covered with golden brown setae on basal three segments. Antenna twice forewing length; dark brown, with narrow patches of pale sensilla on anteromesal surface of each flagellomere. Dorsal pterothorax dark brown, mesoscutellum golden brown; ventrolateral thorax golden. Femora golden; tibiae golden; tarsi dark brown. Metathoracic leg of male with posterior fringe of long setae. Tibial spur formula 2,4,4. Forewing flat; dark brown; with two transverse bands; proximal band ivory, reaching posterior wing margin, at least 1/2 width of wing, an inverted Vshape; distal band ivory, beginning at anterior wing margin, at least 1/2 width of wing; with two basal stripes, ivory. Hind wing basal brush present in male and female; female brush short.
Male. Preterminalic abdominal terga with anteromesal notch. Corematic structures present. Tergum IV with expanded lateral flanges, lateral coremata; lateral coremata singlelobed and short, cylindrical. Tergum V without sclerotized modifications (
Fig. 64F
). Sternum VII with short, acute anteromesal process. Sternum VIII enclosing base of elongate sternum IX; posteromesal process notched (
Fig. 64A, C
). Tergum IX with paired mesal ridges extending 1/2 length of segment; posterior margin with round narrow mesal projection (
Fig. 64B
); lateral ridge absent; dorsal pleural setae approximately 5, ventral pleural setae approximately 8 (
Fig. 64A
). Preanal appendage longer than tergum X, but less than 11/2 times length, widest apically, setae filamentous, longer than appendage (
Fig. 64A, B
). Tergum X without basal lobes; basodorsal process short and digitate; basolateral processes long, length at least twice diameter; apex, in lateral view, rounded, in dorsal view, entire (
Fig. 64A, B
). Harpago rounded; peglike setae many, apical (
Fig. 64A, C
). Phallic endotheca with paired basolateral lobes, basolateral lobes tapered apically; phallotremal sclerites average size, longest dimension less than diameter of phallobase; dorsal sclerite ovoid, in dorsal view horseshoeshaped (
Fig. 64D, E
).
Female. Preterminal abdominal terga with anteromesal notch. Sternum VII with short pointed anteromesal process. Tergum VIII without posterolateral brush; sternum VIII with shallow posteromesal notch, or posterior margin entire; sternum VIII (
Fig. 65C
). Tergum IX without mesal ridge (
Fig. 65B
). Sternum IX anterior and posterior lobes darkly sclerotized and striate, with patch of lightly sclerotized cuticle lateral to vaginal opening (
Fig. 65A
). Tergum X appendage shorter than mesal lobe, base marked by faint suture line, apex oblique; mesal lobe lightly sclerotized; digitate lateral processes length approximately equal diameter (
Fig. 65B
). Sternum X with patches of short fine setae posterolaterally to anal opening (
Fig. 65A
). Vaginal apparatus anterior and posterior sclerites equal in length; anterior sclerite rounded anteriorly, posterolateral projections absent; posterior sclerite triangular; posterior end of spermatheca a sclerotized ovoid (
Fig. 65A
).
