Phylloicus mexicanus ( Banks, 1900:257)   [Type locality: Mexico, Morelos, Cuernavaca; MCZ; male (Bank’s description implies type is female, but specimen with type label is a male); in Heteroplectron   ]. — Flint 1967:17 [as synonym of aeneus   ]. — Wiggins 1996:224 [larva, as aeneus   ].

The type of H. mexicana   is a male from Cuernavaca, Mexico. The terminalia are very similar to those of P. aeneus   and P. nigripennis   males. No abdominal coremata are present, and thus it is not conspecific with P. aeneus   . The wings are very dark and uniformly colored. The head and thorax are black, except for an orange diamond dorsally on the head. The specimen is very large (forewing length 12.4 mm, compared to 5.9 mm for the P. nigripennis   male). Other specimens of this form are from Arizona and the Sonoran Desert regions of Mexico. They are consistently much larger than specimens of P. nigripennis   , and have the black wings and thorax, and the orange diamond on the head, of the type specimen. The abdomens of these specimens are orange. Because of its very different size and body coloration, I am recognizing P. mexicanus   and removing it from synonymy.

Adult. Forewing length 12.4­16.2 mm, n = 122.

Head black, except for orange diamond dorsomesally ( Fig. 2, 3 View FIGURES 1­3. —1 ). Maxillary palps black. Antenna of male twice forewing length; female antenna 11/2 times forewing length; black, with narrow patches of pale sensilla on anteromesal surface of each flagellomere. Prothorax orange; dorsal pterothorax black; ventrolateral thorax dark brown. Legs dark brown. Metathoracic leg of male without posterior fringe. Tibial spur formula 2,4,3. Forewing apical third folded obliquely toward midline; dark brown, or black; without colored markings. Hind wing basal brush present in female, short and light brown.

Male. Preterminalic abdominal terga with anteromesal notch. Corematic structures absent, terga III­V unmodified, without membranous lobes or sclerotized processes. Sternum VII without anteromesal process. Sternum VIII similar to anterior sterna, sternum IX not elongate. Tergum IX with short mesal ridge extending from anterior notch; posterior margin with irregular mesal projection ( Fig. 70B View FIGURE 70 ); lateral ridge absent; dorsal pleural setae approximately 6, ventral pleural setae approximately 3 ( Fig. 70A View FIGURE 70 ); sternum IX with paired mesolateral ridges; sternum IX ( Fig. 70C View FIGURE 70 ). Preanal appendage approximately length of tergum X, of uniform diameter throughout length, setae long, but not filamentous or longer than appendage ( Fig. 70A, B View FIGURE 70 ). Tergum X sagittate basally; basodorsal process short and digitate; basolateral processes of varying length and often asymmetrical; apex, in lateral view, acute, in dorsal view, notched, notch deep and round ( Fig. 70A, B View FIGURE 70 ). Harpago slightly tapered; peglike setae few, apical ( Fig. 70A, C View FIGURE 70 ). Phallic endotheca with paired basolateral lobes, basolateral lobes large and round; phallotremal sclerites average size, longest dimension less than diameter of phallobase; dorsal sclerite two­armed, in lateral view Ushaped ( Fig. 70D, E View FIGURE 70 ).

Female. Abdominal tergum I black. Preterminal abdominal terga with anteromesal notch. Sternum VII without anteromesal process. Tergum VIII with dense posterolateral brush of setae ( Figure 71B View FIGURE 71 ); sternum VIII cleft posteromesally to anterior ridge; sternum VIII ( Fig. 71C View FIGURE 71 ). Tergum IX without mesal ridge ( Fig. 71B View FIGURE 71 ). Sternum IX anterior and posterior lobes darkly sclerotized and striate, with patch of lightly sclerotized cuticle laterally ( Fig. 71A View FIGURE 71 ). Tergum X appendage longer than mesal lobe, base marked by faint suture line, apex triangular; mesal lobe lightly sclerotized; digitate lateral processes length approximately equal diameter ( Fig. 71B View FIGURE 71 ). Sternum X without setae in membrane ( Fig. 71A View FIGURE 71 ). 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 cone ( Fig. 71A View FIGURE 71 ).
