Heterick (2006) - Monomorium subopacum, like Monomorium pharaonis, is something of a tramp, and its occurrence in Madagascar and other regions well away from its natural area of occurrence is certainly due to human activities (Bolton 1987).

Identification

Heterick (2006) - A member of the M. subopacum complex in the M. salomonis species group. Monomorium subopacum is very similar to Monomorium willowmorense but those worker specimens I have seen of the former can be distinguished from M. willowmorense by their finely granulate-reticulate frons, uniformly sculptured promesonotal humeri and a longer antennal scape (SI > 100 in M. subopacum and < 100 in M. willowmorense). Nonetheless, the differences that separate the two are small, and in view of the variability to be found in M. subopacum I would not be surprised if molecular–based investigations resulted in M. willowmorense being added to the already overburdened synonymic list for M. subopacum.

Type Material

Lectotype: worker, Madeira, T. V. Wollaston (The Natural History Museum). In view of the subtle differences that separate genuine good species in the M. salomonis group, I am designating a lectotype to fix the name ‘subopacum’, the type worker material of which is a richer reddish brown than the type material for M. glyciphilum. The syntype material is on a single card rectangle. The lectotype worker is the third worker from the RHS, seen from the rear. Paralectotypes: Three workers and three queens, carded on the same rectangle as the holotype (BMNH). No attempt has been made to separate the ants

Taxonomic Notes

Heterick (2006) - Bolton (1987) recognized this species from Madagascar on the basis of a short series from Maevatanana (“Maevantanara”); however, there are no Malagasy specimens in the CAS, despite the huge amount of Monomorium material collected by Brian Fisher and his teams since the early 1990s. The Malagasy component in the description and measurements provided above includes details from six specimens held at UCDC and three specimens from the same series held at MCZ.

Several of the synonyms are those of taxa originally described from males. The spurious genus ‘Paraphacota’ incorporated three such taxa, and what appears to me to be two distinct species. The male of Monomorium surcoufi and that of M. cabrerai are obviously identical, and easily recognized by their long, bicolored legs and completely hyaline wings. On the other hand, the male of Monomorium cabrerai obscuripes has relatively shorter, uniformly dark legs and brown wing veins. I have not seen nest material of Monomorium subopacum that has included males, but Bolton (1987) was in no doubt that the descriptions of M. surcoufi and M. cabrerai were based on ordinary males of M. subopacum. He followed Santschi in also placing M. cabrerai obscuripes under M. subopacum but allowed that it could be the male of Monomorium medinae Emery, a Canary Islands endemic, a view first broached by Wheeler (1927). Hohmann et al. (1993) included the two cabrerai taxa under Monomorium medinae, but omitted Monomorium surcoufi. This seems to me an odd judgement, and, indeed, Bolton (1995) did not mention these authors at all in relation to ‘Paraphacota’, but continued to consign all three taxa to synonymy under Monomorium subopacum. (NB. Dr. Xavier Espadaler [pers. commun.] also places M. cabrerai under M. subopacum, leaving M. cabrerai obscuripes as an unresolved puzzle, but has indicated that none of the males originally placed under ‘Paraphacota’ belongs to Monomorium medinae.)

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.

Male

Heterick (2006) - LECTOTYPE (Monomorium surcoufi): HL 0.88 HW 0.98 CeI 111. (NB. Lectotype lacks antennae, postpetiole and gaster). HOLOTYPE (Monomorium cabrerai): HML (Holotype lacks postpetiole and gaster) HL 0.89 HW 0.96 CeI 108 SL 0.29 SI 30 PW 1.00.

I have only seen damaged male specimens (lectotypes for the taxa Monomorium surcoufi, Monomorium cabrerai and Monomorium cabrerai obscuripes). As there has been controversy over the assignment to M. subopacum of at least the males of Monomorium cabrerai obscuripes and the other males are tattered and lack body parts, no formal description of the abovementioned males is included here.
