Phylloicus View in CoL “species 2" Flint, 1991:99.

Phylloicus munozi is similar to P. blahniki , but is distinguished by the unmodified tergum III, the absence of posterior processes of tergum IV and a complex lateral sclerite ( Fig. 74F View FIGURE 74 ), and the long digitate basodorsal process of tergum X ( Fig. 74A, B View FIGURE 74 ).

Adult. Forewing length 9.7­10.5 mm, n = 17.

Head golden brown. Maxillary palps dark brown. Antenna twice forewing length; dark brown, with narrow patches of pale sensilla on anteromesal surface of each flagellomere. Dorsal pterothorax golden brown; ventrolateral thorax pale tan. Legs pale tan. 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 pale orange­yellow, reaching posterior wing margin, at least 1/2 width of wing, narrow, less than 10 setae wide; distal band pale orange­yellow, not reaching either wing margin, 1/2 width of wing or less, narrow, less than 10 setae wide; with two basal stripes, ivory; cell Cu and base of cell Cu 2 clear. Hind wing basal brush present in male.

Male. Preterminalic abdominal terga with anteromesal notch. Corematic structures present. Tergum IV with paired lateral sclerites, mesal coremata and lateral coremata; lateral sclerite spatulate, directed laterally and with acute basomesal process; lateral coremata with basal globose lobes and long tubular posterior lobe; mesal coremata single­lobed, setose, capable of inflation beyond terminalia. Tergum V without sclerotized modifications ( Fig. 74F View FIGURE 74 ). Sternum VII with short, acute anteromesal process. Sternum VIII similar to anterior sterna, sternum IX not elongate. Tergum IX without mesal ridge; posterior margin continuous with basodorsal process of tergum X ( Fig. 74B View FIGURE 74 ); lateral ridge present; dorsal pleural setae approximately 2, ventral pleural setae absent ( Fig. 74A View FIGURE 74 ); sternum IX without mesolateral ridges; sternum IX ( Fig. 74C View FIGURE 74 ). Preanal appendage approximately length of tergum X, of uniform diameter throughout length, setae long, but not filamentous or longer than appendage ( Fig. 74A, B View FIGURE 74 ). Tergum X without basal lobes; basodorsal process long and digitate; basolateral processes absent; apex, in lateral view, truncate, in dorsal view, entire ( Fig. 74A, B View FIGURE 74 ). Harpago slightly tapered; peglike setae many, apical ( Fig. 74A, C View FIGURE 74 ). Phallic endotheca with paired apicolateral lobes and paired basolateral lobes, basolateral lobes tapered apically, apicolateral lobes large and rounded; phallotremal sclerites average size, longest dimension less than diameter of phallobase; dorsal sclerite ovoid, in dorsal view horseshoe­shaped ( Fig. 74D, E View FIGURE 74 ).

Female. Preterminal abdominal terga with anteromesal notch. Sternum VII with short pointed anteromesal process. Tergum VIII without posterolateral brush; sternum VIII posterior margin entire; sternum VIII ( Fig. 75C View FIGURE 75 ). Tergum IX without mesal ridge ( Fig. 75B View FIGURE 75 ). Sternum IX anterior and posterior lobes darkly sclerotized and striate, with patch of lightly sclerotized cuticle lateral to vaginal opening ( Fig. 75A View FIGURE 75 ). Tergum X appendage shorter than mesal lobe, base marked by faint suture line, apex oblique; mesal lobe lightly sclerotized; digitate lateral processes absent ( Fig. 75B View FIGURE 75 ). Sternum X with patches of short fine setae posterolaterally to anal opening ( Fig. 75A View FIGURE 75 ). Vaginal apparatus anterior and posterior sclerites equal in length; anterior sclerite rounded anteriorly, posterolateral projections absent; posterior sclerite triangular ( Fig. 75A View FIGURE 75 ).
