Joma and Mackay (2015) - A member of the Bothroponera pumicosa species complex. The workers of Bothroponera laevissima are large (total length 12 - 13 mm) shiny black ants. The mandibles are shorter than the head length and covered with fine striae. The anterior medial raised area of the clypeus is convex, but lacks a longitudinal carina; the anterior border is “u” shaped. The lower margin of the clypeus has a short grooved beak on the lower margin of the posteroclypeus. The metapleural area is compressed in some specimens.
The head is smooth and shiny with few punctulae scattered on the surface. The pronotum, mesonotum, mesopleuron, propodeum, petiole and postpetiole are smooth and shiny with a few scattered punctulae. The petiole is more sculptured than the other body parts. The second gastral tergite is smooth and glossy.
The worker of B. laevissima can be recognized as a shiny black ant. The general characters of the worker of B. laevissima are similar to those of the worker of Bothroponera aspera, but the lower margin of the anterior medial raised area of the clypeus has a “u” shape in B. laevissima while it has “v” shape in B. aspera. The lower margin of the clypeus forms a grooved beak in B. laevissima, which is not found in B. aspera. Despite that they both have a shiny surface and black color, B. laevissima is characterized by a smooth head with few scattered punctulae, similar to the pronotum, mesonotum, mesopleuron, propodeum, petiole and postpetiole. The petiole is more sculptured than other body surfaces; the second gastral tergite is smooth. Conversely, B. aspera is recognized as rough with dense shallow punctulae on the body surface (head, pronotum, mesonotum, mesopleuron, propodeum, petiole and postpetiole), the tergum of the second-fifth gastral segments are mostly smooth and glossy. Due to the mostly polished sculpture, B. laevissima would not be confused with any other species except B. aspera. Bothroponera laevissima was collected from Saldanha Bay, Western province area of South Africa, where B. aspera also occurs, which further suggests they are separate species.
