The Ants of Africa
Genus Trichomyrmex
Trichomyrmex emeryi (Mayr)

The subgenus Parholcomyrmex was defined by Emery (1915i: 190), type species Monomorium gracillima (as Myrmica gracillima, now junior synonym of Trichomyrmex destructor) - see {original description}. The main characteristics Emery listed were - slightly dimorphic workers; funiculus with a three-segmented club (Monomorium santschii with four segmented-club, type location Tunisia), the first two segments equi-sized.

{Monomorium emeryi}Mayr's (1895) description is at {original description}. Arnold's (1916) translation of Mayr (1895) and descriptions of the queen and male are at {original description} and {original description}. Mayr's (1897) description of laevior is at {original description}. Bolton's modern description (1987) is at {original description}, he does not mention laevior, the listing is in his Catalogue (1995: 263).

WORKER - diagnosis as in key; TL 2.5-3.4 mm; (in Bolton, 1987: 325, not illustrated).

As Bolton (1987) noted, this species, with its heavy sculpture, including striated mandibles, is quite distinct from the other species he (Bolton) placed in the group. Although Bolton stated he examined a total of twenty specimens, including the holotype, he provided no illustration and makes no reference to the illustration given by Arnold (above right). That illustration shows a very different head shape and a funiculus without a distinct club - the inclusion in this group, therefore, seems dubious. A more appropriate placement, perhaps, would be in the scabriceps-group.
