Joma and Mackay (2015) - A member of the Bothroponera pumicosa species complex. The head of the worker is subquadrate and the mandibles are smooth and covered with hairs. The anterior medial margin of the clypeus is convex and forms a “u” shaped edge, and the clypeus has a raised medial sharp carina which extends from the base of the frontal furrow to the lower medial margin of the clypeus.
Bothroponera strigulosa is similar to Bothroponera cariosa, and Bothroponera pumicosa, as they all have a “u” shaped anterior medial margins of the clypeus. Bothroponera strigulosa is quite similar to B. cariosa, but it can be distinguished because the mandibles of B. strigulosa are smooth and shiny while in B. cariosa they are covered with fine striae. The mandibles in B. pumicosa are hairy and smooth. The hairs are long (from 0.20 up to 0.55 mm) in B. pumicosa while they are short in B. strigulosa (from 0.05 up to 0.32 mm) and B. cariosa (from 0.05 up to 0.25 mm).
The characters of Bothroponera strigulosa are similar to those of Bothroponera berthoudi. The only apparent differences between them are that the raised medial area of the clypeus of B. berthoudi is smooth and the clypeal carina is not present, but B. strigulosa has a clypeal carina (it partially forms a carina in B. pumicosa). The erect golden hairs on most surfaces are slightly longer in B. berthoudi than those of B. strigulosa.
