Subfamily Heliconiinae.: A largely pantropical group, with one of the five tribes found in the Holarctic Region.
​
Tribe Acraeini: There are two Afrotropical genera contained within this tribe; Telchinia and Acraea, both represented at Semuliki. There are 138 described Afrotropical species within this tribe with 104 species recorded in Uganda. At Semuliki a total of 45 species from both genera have been recorded: 25 from the genus Telchinia and 20 species of Acraea, contributing to a third of the Ugandan species total.
Genus Cymothoe: There are 15 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 90% of Uganda's total. The two Ugandan species not being recorded at Semuliki being C. distincta and C. indamora, but with both these species being recorded either in the Ituri Forest or Semliki Valley (Ducarme, 2018) it is a distinct possibility that they will also be found in 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 nd 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 for the genera Bebearia, Euphaedra and Euriphene.

Genus Charaxes: The genus Charaxes is a predominantly Afrotropical genus containing 186 described species with a further eight species recorded from the Oriental region. There are 64 species recorded from Uganda with Semuliki having 41 recorded so far, contributing an impressive 62% of all Ugandan species.
The taxonomic groupings used below will follow the phylogeny as proposed by Aduse-Poku et al. (2009) from genetic analysis. This merged the historically typical three genera make-up (Charaxes, Polyura and Euxanthe) of the Charaxini into a monophyletic grouping under the single genus Charaxes. This single genus was then divided into five subgenera which were then split into 24 species groups.
The latest systematic revision (Bouyer, 2023) proposes a nine genera grouping. This comprises the genus Charaxes and the reinstatement of the two genera, Euxanthe and Polyura (merged by Aduse-Poku et al., 2009), revising a further three genera (Zingha, Eriboea, Viridixes) and creating three new genera (Ydeali, Laodice and Setechin). The Euxanthe genus is split into two subgenera and a further 26 species groups are detailed for the remaining eight genera.
​
The Metamorphosis publication 'The butterflies (Lepidoptera: Papilionoidia) of Semuliki National Park, western Uganda', Forbes (2018) lists Charaxes smaragdalis ssp. as caerulea - this should be amended to leopoldi.

Subgenus Charaxes. There are 10 Afrotropical species-groups within this subgenus.
species group Jasius. There are five species recorded at Semuliki within this group: C. epijasius, C. brutus, C. pollux, C. eudoxus and C. castor. C. epijasus was sampled only once when traps were located in the grassland patch. C. brutus was also rare and trapped only once. C. eudoxus was recorded from a specimen from The National Museum of Scotland (entomology collections) but was never live trapped at Semuliki. C. pollux was frequently sampled in the nets but never in abundant numbers. C. castor was never trapped but was sampled by Davenport (1996).

species group Hadrianus. There are two species within this group and one has been recorded at Semuliki: C. hadrianus. Only one specimen was ever recorded in the fruit-traps and then only recorded 200 m from the main sampling transect within the forest interior.

Charaxes hadrianus
species group Zingha. There is only one species within this group: C. zingha. Only one specimen was ever recorded in the fruit-traps and this was captured at the forest margins.

Charaxes zingha
species group Tiridates. There are 20 species within this group and seven have so far been recorded at Semuliki: C. numenes, C. tiridates, C. bipunctatus, C. smaragdalis, C. imperialis, C. ameliae and C. pythodoris. The relatively common species sampled in the traps are C. numenes, C. tiridates, C. ameliae and C. imperialis. The other 3 species: C. bipunctatus, C. smaragdalis and C. pythodoris were trapped only once.

species group Varanes. Three species have so far been recorded from Semuliki: acuminatus, varanes and fulvescens. Only fulvescens could be described as common while acuminatus and varanes were rarely trapped or observed.

Charaxes protoclea
species group Lucretius. Only one of the four species described in this group has been recorded at Semuliki: C. lucretius. This was a rare species and only one male was trapped.

Charaxes lucretius
Subgenus Euxanthe. There are two species-groups within this subgenus: Euxanthe and Lycurgus.
species group Euxanthe. There are three species recorded at Semuliki from the six species described within this group: C. eurinome, C. crossleyi and C. trajanus. These three species were net sampled and not found within the fruit traps. Each of these species were predominantly sampled along the forest margins within a less dense understorey than the forest interior.

species group Lycurgus. There are two recorded species from this group: C. lycurgus and C. zelica. Only one was trapped within my sampling periods while C. zelica was identified from a specimen from The National Museum of Scotland (collections department).

Charaxes lycurgus
Charaxes zelica
Subgenus Polyura. There are two Afrotropical species-groups within this subgenus.
species group Pleione. There are only two species recorded at Semuliki within this group: C. paphianus and C. pleione. Both species were uncommon and trapped within the forest margins.

Charaxes paphianus

Charaxes pleione
species group Zoolina. There is only one species recorded at Semuliki within this group: C. khaldeni. This was trapped by Tim Davenport in his census of 1996 and the collected specimens provided to Makerere University in Kampala. The species was never observed during my sampling periods.
-ink.jpeg)
Charaxes kahldeni
Subgenus Eriboea. There are six Afrotropical species-groups within this subgenus.
species group Eupale. There are only two species recorded at Semuliki within this group: C. eupale and C. minor. Only C. eupale was trapped during my sampling periods along the forest margins.

Charaxes etesipe
species group Anticlea. Of the six species described within this clade only one is found at Semuliki: C. anticlea. Again a rare species which was only trapped once along the forest margins.
-ink.jpeg)
Charaxes anticlea
species group Hildebrandti. Only one species is recognised in this group: C. hildebrandti which is split into three subspecies of which a specimen of C. hildebrandti katagensis has been labelled within the National Museum of Scotland Collections Dept. This looks like an identification error with the subspecies more likely the nominate subspecies which has been located in both the Central Forest Block and the Ituri Forest of the DRC (Ducarme, 2018).

Charaxes hildebrandti
species group Etheocles. This group includes the 'black charaxes' of which there are six species recorded at Semuliki: C. virilis, C. viola, C. catachrous, C. etheocles, C. baumanni and C. cedreatis. The males are characteristically very difficult to differentiate and so the evidence of a species presence is often with an identification of the female. The female (which can have many forms) will be displayed along with a male, based on descriptions from 'The Charaxinae Butterflies of Africa' by Stephen Henning.

Subgenus new. A new subgenus to incorporate only one species, Charaxes nichetes.
Species group Nichetes. C. nichetes was identified from the National Museum of Scotland, entomology collections department as being recorded from Semuliki.

Field Images: There are field images for the majority of species recorded. Some were recorded from the 1996 park survey of Semuliki and not trapped during my sampling periods. Also unfortunately an sd card full of images was corrupted. Fortunately, the Charaxes species that had no complementary field image had been identified prior to the sd card being corrupted, of the ones trapped by myself. The species with no field image will be the focus of further field trips to Semuliki.
