Mouthparts well developed: galea hooked with longer than 2/3 of labial palpus; maxillary palpus and labial palpus covered with light yellow scales; maxillary palpus 5 segmented; labial palpus 3 segmented.
In adults, PB is required for patterning the maxillary palpus and PB with SCR is required for patterning the proboscis [12, 13].
Palpus brownish yellow and triangulate (obtuse scalene shape) (Fig.
Head: Arista bare; clypeus strongly convex, entirely microsetulose; palpus parallelsided, densely microsetulose, with a few small setulae, but lacking outstanding setae; lower frons flat, projecting slightly anterior to eyes, supra-antennal shelf distinct; frontal vitta with small, elevated area restricted to upper 1/2; lower 1/2 of frons flat with straight margin; 2 pairs of fronto-orbital setae, posterior pair usually at or behind level of ocelli.
africana larvae express the three features previously identified as potential synapomorphies for Nothochrysinae [7], including (i) antenna: terminal segment is short (~ten times shorter than remainder of antenna), (ii) antenna: terminus has a group of small apical setae, not an elongate seta, (iii) labial palpus: terminal segment has more than three lateral sensilla.
Cardo reduced; stipes prominent, trapezoidal with two prominent falcate medial sensilla; galea finger-like, approximately 1/3 the length of palpomere (MP) 1; palpus length, excluding palpifer.
Ontogeny and homology in the male palpus of orb-weaving spiders and their relatives, with comments on phylogeny (Araneoclada: Araneoidea, Deinopoidea).
The palps are somewhat Charaxes-like, being S-shaped and porrect; the basal sensory patch of the palpus is broad and elongated, which places Anaeomorpha somewhere between Prepona and Polygrapha Schatz, the latter genus as a member of Anaeinae group (SALAZAR & CONSTANTINO (2001)) in their Synthesis of Colombian Charaxids consider that the taxonomic position of the species is probably located between Archaeoprepona and Pseudocharaxes Salazar & Constantino: type species "Paphia" (Polygrapha) xenocrates Westwood, 1850, but this hypothesis is not supported by the evidence presented".
These include stripe (8), greenish brown (9), black (10), diamond palpus (11), black scale (12), golden-yellow (13), green (14), yellow (15), brown (16), pale and dark colour (17), greyish brown (6), grey (18), greyish black (19), and dark mutant (7).
The nomenclature of the male palpus and female epigynum structures follows Redner & Dondale (1983).
