Genus Cymothoe: There are 16 species of the Afrotropical genus Cymothoe so far recorded at Semuliki from a continent total of 78 (Williams, 2018) and a Ugandan total of 17 (Williams, 2015), or nearly 95% of Uganda's total. The only Ugandan species not being recorded at Semuliki being C. indamora, however this species has been recorded both in the Ituri Forest and the DRC Semliki Valley (Ducarme, 2018) and so it is a distinct possibility that it will also be found at Semuliki. Only three species are frequently sampled in traps and these are C. sangaris, C. cyclades and C. confusa. This genus has been categorised into clades and the most commonly trapped species C. confusa had a distinctly clumped distribution within Semuliki. Species from this genus were observed more in the forest midstorey as compared to the preference of the forest floor of the genera Bebearia, Euphaedra and Euriphene.
Caenis Clade. There is only one species, C. caenis of this clade recorded at Semuliki. Females come in a variety of colour forms and the caenis-complex taxonomy is still unravelling (Van Velzen et al., 2009). This is not a rare species at Semuliki but not as often sampled as the three most common species. Both the males and females are morphologically variable.
Incertae sedis. A number of species have not been assigned to any of the named clades. One of these species is C. beckeri, a rarely observed species that was never trapped within the traditional Van Someren-Rydon style trap, but in a net on the forest fringes. Another unclassified species, C. cyclades is a commonly observed and sampled species within the forest. Along with C. confusa, these two species are the most abundant Cymothoe species. C. jodutta was another uncommon species and rarely trapped.
Egesta Clade. C. confusa is a commonly observed and sampled species with a clumped distribution within the forest. Possibly influenced by the distribution of its food plant.
Adela Clade. C. ochreata is another relatively common sampled species. There is only one species recorded at Semuliki from this clade of 5 Afrotropical species.
Lurida clade. There are five species assigned to this clade, two have been recorded at Semuliki: C. lurida and C. colmanti. Both species were rarely encountered in the traps. Only one male of C. lurida was trapped.
Fumana clade. There are two species assigned to this clade with one having been recorded at Semuliki: C. haynae. This was a very rare species and only the female was encountered. It was only ever trapped at one site and so appeared to be site-specific.
Sangaris clade. There are four species assigned to this clade with two species: C. sangaris and C. hobarti being recorded at Semuliki. C. sangaris was a seasonally common species while C. hobarti was sampled only once, a female. C. hobarti replaces C. sangaris as the easternmost population of the sangaris-complex.
Coccinata Clade. There are 14 species included in this clade of which four have been recorded at Semuliki: C. reginaeelisabethae, C. coccinata, C. distincta and C. meridionalis. The three species sampled can be considered uncommon and are rarely trapped while C. distincta has not yet been sampled within the traps.
Cymothoe distincta (waiting on museum image)
Herminia Clade. C. herminia is the only species recorded at Semuliki from the three species described for this group. Again an uncommon species which was rarely encountered either observed or in the traps.
Field Images: There are field images for all but three species: C. meridionalis, C. herminia and C. distincta. Unfortunately an sd card full of images was corrupted. Fortunately, two of the Cymothoe species that have no complementary field image had been identified prior to the sd card being corrupted, in this case C. meridionalis and C. herminia. The species C. distincta has so far not been sampled within the traps or observed in the field while out sampling.
