Phylloicus elegans Hogue and Denning, 1983   in Denning et al. 1983:184 [Type locality: Panama, Canal Zone, Barro Colorado Island; WSU; male]. — Flint 1991:98 [male, distribution].

The wing pattern of P. elegans   ( Fig. 109 View FIGURES 109-112. — 109 ) is identical to that of P. lituratus   . However, the male abdomen of P. elegans   is very distinctive: tergum IV has distinctively shaped posteriorly projecting lateral sclerites and multilobed lateral coremata ( Fig. 43F View FIGURE 43 ). The females of the two species are indistinguishable, and as several series from different localities contain males of both P. elegans   and P. lituratus   , all determinations of females are tentative. Hybrids may occur; this is discussed under P. lituratus   .

Adult. Forewing length 10.4­12.1 mm, n = 106.

Head chestnut brown. Maxillary palps dark brown. Antenna twice forewing length; chestnut brown, with narrow patches of pale sensilla on anteromesal surface of each flagellomere. Dorsal pterothorax chestnut brown; ventrolateral thorax golden. Femora golden; foretibiae dark brown; mesotibiae dark brown; metatibiae dark brown; foretarsi dark brown; mesotarsi white proximally, dark distally; metatarsi dark brown. Metathoracic leg of male with posterior fringe of long setae, setae dark. 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 ( Fig. 109 View FIGURES 109-112. — 109 ). Hind wing basal brush present in male and female; male brush light brown; female brush dark brown.

Male. Preterminalic abdominal terga with anteromesal notch. Corematic structures present. Tergum IV with paired posterior processes and paired lateral sclerites, lateral coremata; posterior process truncate; lateral sclerite spatulate, directed laterally; lateral coremata with basal globose lobes. Tergum V without sclerotized modifications ( Fig. 43F View FIGURE 43 ). Sternum VII with short, acute anteromesal process. Sternum VIII enclosing base of elongate sternum IX; posteromesal process notched, notch deep and round ( Fig. 43A, C View FIGURE 43 ). Tergum IX with mesal ridge extending full length of segment; posterior margin with round narrow mesal projection ( Fig. 43B View FIGURE 43 ); lateral ridge present; dorsal pleural setae approximately 4, ventral pleural setae approximately 2 ( Fig. 43A View FIGURE 43 ). Preanal appendage at least 11/2 times length of tergum X, widest apically, setae filamentous, longer than appendage ( Fig. 43A, B View FIGURE 43 ). Tergum X without basal lobes; basodorsal process short and digitate; basolateral processes short, length less than or equal to diameter; apex, in lateral view, truncate, in dorsal view, entire or notched, notch shallow; with paired dorsolateral ridges ( Fig. 43A, B View FIGURE 43 ). Harpago rounded; peglike setae many, apical ( Fig. 43A, C View FIGURE 43 ). Phallotremal sclerites average size, longest dimension less than diameter of phallobase; dorsal sclerite ovoid, in dorsal view horseshoe­shaped ( Fig. 43D, E View FIGURE 43 ).

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. 44C View FIGURE 44 ). Tergum IX without mesal ridge ( Fig. 44B View FIGURE 44 ). Sternum IX anterior and posterior lobes darkly sclerotized and striate, with patch of lightly sclerotized cuticle lateral to vaginal opening ( Fig. 44A View FIGURE 44 ). Tergum X appendage shorter than mesal lobe, base indistinct, apex oblique; mesal lobe lightly sclerotized; digitate lateral processes absent ( Fig. 44B View FIGURE 44 ). Sternum X with patches of short fine setae posterolaterally to anal opening ( Fig. 44A View FIGURE 44 ). Vaginal apparatus anterior and posterior sclerites equal in length; anterior sclerite truncate anteriorly, posterolateral projections absent; posterior sclerite triangular; posterior end of spermatheca a sclerotized cone ( Fig. 44A View FIGURE 44 ).
