The identity of P. aeneus  has been the subject of some confusion, largely due to the holotype being a female in very poor condition. Several authors have redescribed this species based on specimens mistakenly associated with the type female, and thus judged P. nigripennis  , mexicanus  , latus  , and sagittosa  to be conspecific with P. aeneus  . Based on the evidence discussed below, mexicanus  and nigripennis  are valid species — with latus  and sagittosa  junior synonyms of the latter — and ornatus  and centralus  are synonyms of aeneus  .

Hagen (1861) described Macronema aeneum  from a female specimen labeled “Sallé, V.C.” [for Veracruz, Mexico, handwritten on a single green label]. Ross (1952) identified this type specimen in a paper on lectotypes of Hagen species in the Museum of Comparative Zoology. He did not refer to the specimen as a lectotype in the paper. A yellow label in Ross’s hand on the specimen names it lectotype, but there is nowhere in Hagen’s original description or Ross’s 1952 paper (except by implication in the paper’s title) any indication that it was selected from among the type series. This specimen is badly damaged; the abdomen, which has been cleared and placed in a microvial of glycerin, is in many pieces; only a portion of one forewing remains, and even this is faded, so that it is not possible to determine what color pattern it might once have exhibited, although the epithet “ aeneum  ” translates as “coppery.” The holotype female of M. aeneum  bears a tuft of dark stout setae at each posterolateral margin of tergite VIII.

The female holotype of Notiomyia ornata  was collected in central Texas. It is in good condition and the wing pattern is clearly discernable. The pattern is very distinctive, and the species can be easily discriminated on the basis of wing pattern alone. The wings can be described as copper­colored. The tufts of setae on tergite VIII observed in P. aeneus  are present also on the female holotype of N. ornata  . I have seen these setal tufts only on females of P. aeneus  , ornatus  , mexicanus  , and panamensis  , new species. Specimens of P. mexicanus  have other distinguishing characters that rule out conspecificity; of the remaining two species, only P. ornatus  is known to be from Mexico. The terminalia of the type specimens of P. aeneus  and ornatus  are indistinguishable. Only one form of Phylloicus  is found in Texas, and thus there is no doubt of the association of male and female. The males bear short coremata on abdominal segment IV, with very short, broad projections of the posterolateral tergal margin.

The male holotype of M. centrale  has terminalia and modifications of abdominal segment IV identical with those observed in P. ornatus  males. The wing pattern is faded, but what remains is consistent with the distinctive pattern of P. ornatus  .

Ulmer redescribed P. aeneus  based on several specimens from Morelos; these specimens appear to be conspecific with the type of P. nigripennis  . Flint (1967) compared the female types of aeneus  and nigripennis  and concluded that they were conspecific; he illustrated a male labeled “ Mexico, Sallé,” stating that it was probably part of the original type series. I have examined this and another specimen labeled “ Mexico, Sallé,” and labeled by Flint in 1965, as Phylloicus aeneus  male. The collection labels on these specimens are printed (possibly cut from a journal article) with “ Mexico ” on the upper label, and “Sallé” on the second label; these labels do not resemble those on the type of aeneus  except in the collector’s name. These specimens are males of P. nigripennis  ; the wings are dark and without pattern, no coremata are present on the abdomen, and they exhibit other characteristics consistent only with that species.

The redescription of P. aeneus  by Denning et al. (1983) includes a mention of the abdominal coremata. Their illustrations were prepared from specimens collected in Sonora, which may have been either P. aeneus  or mexicanus  ; if the specimens depicted in the illustration had abdominal coremata, they must have been P. aeneus  .

Given this evidence, the logical conclusion is that P. aeneus  , centralus  , and ornatus  are conspecific.

Pinned specimens of P. aeneus  are easily identified by the distinctive pattern of dark patches near the base of the forewing. As well, in P. aeneus  and mexicanus  , nigripennis  , and panamensis  , there is an oblique fold of the forewing’s apical third, toward the midline ( Fig. 118View FIGURES 117-118. — 117). The male genitalia of P. aeneus  are most similar to those of P. mexicanus  , nigripennis  , and panamensis  . Phylloicus aeneus  may be distinguished from these three species by the presence of short, single­lobed coremata, covered by a short posterior tergal process, on abdominal segment IV.
