However,  M. v. virescensis slightly larger in overall size ( 10–14 mm), punctures smaller shallower and sparser, erect pubescence comparatively shorter, and the integument of pronotal disc more frequently aeneous metallic green. Also, the subsutural eburneous costae of elytra tend to be broader anteriorly, and the lateral collar-like projections on the anterior margin of the pronotum are more prominent in  M. v. virescens. This subspecies is slightly larger than  M. v. virgulataand therefore, the antennae are longer and the antennomeres are more elongate due to the allometric development frequently observed in trachyderines (e.g., Linsley and Chemsak 1961: 28). The antennae of female  M. v. virescenscompared to  M. v. virgulataare usually longer attaining elytral apices or exceeding apices by a half of antennomere while those of the  M. v. virgulatafemale are shorter than body attaining the base of fourth abdominal sternite. In males the antennae exceed the elytral apices in both subspecies with those of  M. v. virescensusually exceeding the apices by three antennomeres and  M. v. virgulatausually by two. The most strikingly distinct hypoallometric feature in the female  M. v. virgulatais the shortened antennae with enlarged or expanded distal antennomeres from antennomere VI as found in  Chemsakiella. The distal antennomeres of  virescensfemales are elongate, slender, and not enlarged. The comparative lengths of antennomeres for several female specimens examined showed that the  M. v. virgulatafemale have antennomeres IV–VII that are shorter than I compared to the  M. v. virescensfemales with antennomere IV subequal to I and V–VII slightly longer than I. Similar examination of several male specimens revealed that  M. v. virgulatahave antennomeres that are thickened or expanded with IV, IX and X that are subequal to or slightly longer than I, while  M. v. virescenshave antennomeres that are slender with IV, IX and X much longer than I.  Mannophorus v. virescensis redesignated as a subspecies of  M. v. virgulatasince my comparative examination did not reveal any other striking difference ( Fig. 202–217) except for the morphology of the antennae ( Fig. 218–221). The examples of dorsal habitus as shown in the figures ( Fig. 218–221) are the extreme forms of the two subspecies. Based on the materials examined,  M. v. virescensranges from southern Puebla (i.e., Petlalcingo, and Chila de las Flores), southward to Oaxaca (i.e., Huajuapan de Leon), west into Guerrero (i.e., from Acahuizotla and Tixtla to Ixateopan), and northward to Morelos (near Cuernavaca). 2005-10-15 BKEC Eya Mexico 23 km N Huajuapan de Leon 49 48 1 1 Oaxaca paratype 2004-10-18 CSCA Belamy Mexico 1833 18.108334 Hwy 21 -97.68694 49 48 6 2 4 paratype 1989-10-14 EMEC R.
