Figs. 80 View FIGURE 80 , 81 View FIGURE 81

Phylloicus panamensis is very similar to P. aeneus , nigripennis , and mexicanus . Like P. aeneus and mexicanus¸ the females of P. panamensis have a brush of setae laterally on tergum VIII. However, these specimens lack the coremata of P. aeneus , the orange diamond on the head distinguishing P. mexicanus , or the papillate terga II and III of P. nigripennis males. All the specimens I examined were preserved in ethanol, so details of wing color pattern or body coloring are unavailable.

Adult. Forewing length 12­13.5 mm, n = 41.

Head golden brown. Maxillary palps golden brown. Antenna twice forewing length; golden brown. Prothorax golden brown; dorsal pterothorax golden brown; ventrolateral thorax golden brown. Legs golden brown. Tibial spur formula 2,4,3. Forewing apical third folded obliquely toward midline; golden brown; without colored markings. Hind wing basal brush present in female.

Male. Preterminalic abdominal terga with anteromesal notch. Corematic structures absent, terga III­V unmodified, without membranous lobes or sclerotized processes. Sternum VII with short, acute anteromesal process. Sternum VIII similar to anterior sterna, sternum IX not elongate. Tergum IX with short mesal ridge extending from anterior notch; posterior margin irregular ( Fig. 80B View FIGURE 80 ); lateral ridge present; dorsal pleural setae approximately 8, ventral pleural setae approximately 5 ( Fig. 80A View FIGURE 80 ); sternum IX with paired mesolateral ridges; sternum IX ( Fig. 80C View FIGURE 80 ). Preanal appendage approximately length of tergum X, of uniform diameter throughout length, setae long, but not filamentous or longer than appendage ( Fig. 80A, B View FIGURE 80 ). Tergum X sagittate basally; basodorsal process absent; basolateral processes absent; apex, in lateral view, rounded, in dorsal view, notched, notch triangular; dorsal surface setose; with anterodorsal lateral processes ( Fig. 80A, B View FIGURE 80 ). Harpago long, curving mesally and tapering apically; peglike setae few, apical ( Fig. 80A, C View FIGURE 80 ). Phallic endotheca with paired basolateral lobes, basolateral lobes large and round and with digitate apical lobe; phallotremal sclerites average size, longest dimension less than diameter of phallobase; dorsal sclerite two­armed, in lateral view U­shaped ( Fig. 80D, E View FIGURE 80 ).

Female. Preterminal abdominal terga with anteromesal notch. Sternum VII with short pointed anteromesal process. Tergum VIII with dense posterolateral brush of setae; Fig. 81B View FIGURE 81 ; sternum VIII cleft posteromesally to anterior ridge; sternum VIII ( Fig. 81C View FIGURE 81 ). Tergum IX with mesal ridge extending 1/3 length of segment ( Fig. 81B View FIGURE 81 ). Sternum IX anterior and posterior lobes darkly sclerotized and striate, punctate, with shallow pockets lateral to vaginal opening ( Fig. 81A View FIGURE 81 ). Tergum X appendage longer than mesal lobe, base marked by faint suture line, apex triangular; mesal lobe lightly sclerotized; digitate lateral processes absent ( Fig. 81B View FIGURE 81 ). Sternum X without setae in membrane ( Fig. 81A View FIGURE 81 ). Vaginal apparatus anterior and posterior sclerites equal in length; anterior sclerite truncate anteriorly, posterolateral projections acute; posterior sclerite ovoid; posterior end of spermatheca a sclerotized sphere ( Fig. 81A View FIGURE 81 ).
