In this image you can see the old missionary house (silver roof) and hospital in the upper left. The area surrounding the mission station is a patchwork of cultivated fields (not seen in this old image, which I believe was taken during the LRA's invasion of the area), savanna & forest. The blue square indicates the spot where these butterflies were collected, just off the main trail.
Poritiinae have an interesting habit of sitting/resting at the tips of tendrils, shoots, and twigs, almost like little flowers or buds. They are closely associated with certain species of ants. Often you'll find several individuals, even in mixed species groups, sitting on the same tendril. When walking along Central African forest trails, one soon develops the instinct to scan probable tendrils & twigs for these Lycaenids.
Larinopoda tera
Mimeresia moreelsi purpurea
Mimeresia drucei ugandae
Males
Female
Mimeresia cf. cellularis/pseudocellularis
I'm not certain which this is. The figures in Papillons du Gabon suggest cellularis , but the MRAC collection points to pseudocellularis. Either way this seems to be a significant range extension.
Pentila umangiana
As best as I can tell, these forms match 2 or 3 currently accepted subspecies of umangiana.
Pentila pauli multiplagata
Unlike the others here, this species isn't tied to ants and is much more tolerant of different environments. I'm cheating by including this specimen as it wasn't caught within the area of the blue box above, but rather just a few 10s of meters to the west, on the edge of a cultivated field.
Pentila cf. cloetensi
My hunch is that these represent an undescribed species.
Pentila tachyroides isiro
Ptelina carnuta
These are tiny little things.
Mimacraea landbecki
Citrinophila erastus erastus
