Description
General (Figs 23, 24): Female body length: 1.8–2.1 mm (n= 20). Male body length: unknown. Head: Color of female head: black. Mandible color: mostly dark brown to black. Body color of male: unknown. Lateral ocellus position: touching compound eye. Pilosity of medial frons between anterior ocellus and apex of torular triangle: absent, a small patch without setae clearly visible. Sculpture of medial glabrous area of frons: present, with horizontal to slightly arcuate striae or, if patch minute, then irregularly rugulose (Fig. 27). Mesosoma (Figs. 25, 26): Color of female mesosoma: dark brown to nearly black. Dorsal surface of lateral pronotal area adjacent to mesoscutal suprahumeral sulcus: with uniform microsculpture only. Setae on netrion: absent. Notaulus: indicated by a row of pits. Metascutellum: projecting, truncated throughout, roughly rectangular. Mesopleural depression sculpture: irregularly foveate, majority of fovea not transverse, fovea interspersed with nitid areas, in some individuals some fovea reduced to punctures, or mostly transversely rugulose, larger fovea absent. Pilosity bounding anterior margin of posterior mesepimeral area: completely absent, or partially present dorsally. Legs: Coxae color: yellow (as in remainder of leg). Color of http://www.morphbank.net/?id= 226855FIGURES 23–28.25 Axea adro, paratype female (OSUC211775). 23, dorsal habitus; 24, lateral habitus; 25, mesosoma, dorsal view; 26, mesosoma, lateral view; 27, head, anterior view; 28, apex of metasoma, dorsal view. Scale bars in millimeters. legs beyond coxae: uniformly yellow, without infuscations. Wings: Length of fore wing: not or just reaching posterior margin of metasoma, or surpassing posterior margin of metasoma. Hind wing submarginal vein: absent to spectral everywhere but basal stub that is nebulous to tubular. Metasoma: Color of female metasoma: dark brown to nearly black, or yellow to amber or orange yellow, or light brown. Longitudinal sculpture of T 1: carinate, parallel to subparallel, interspersed with fine rugulose sculpture. Female T 1 horn: absent, sculpture more or less uniform throughout T 1. Anterior strip of T 2: punctulate. Female T 6 width to http://www.morphbank.net/?id= 226902 length ratio: more or less equal in length (subtriangular). Female T 6 carinate basal extension of lateral spine: short, not extending past 1 / 2 length of T 6. T 6 /S 6 apical curvature: absent, sclerites more or less linear in lateral view, or present, tips flexed outwards in lateral view. T 6 posterolateral margin: with sharp spine (Fig. 28). S 6 shape at tip: broadly rounded to very slightly angular, without obvious lobe.
Diagnosis
Diagnosis. Differentiated from all other species of Axea by the combination of the absence or extreme reduction of the lateral projections and associated carina of T 6 (Fig. 28) and the presence of yellow legs on an otherwise brown to dark brown body (Figs. 23–24).
Etymology
Etymology. Named in reference to a male god of the Lugbara people of Uganda and the Democratic Republic of Congo. Link to Distribution Map.26
Discussion
Comments.Axea adro is presently the most widespread species within Africa. While there is some slight variation in the degree of development of the lateral spines on T 6 the overall morphology is quite uniform throughout its range. This is the only species for which we have some information pertaining to the potential hosts of species of Axea. A long series of males collected in the Democratic Republic of Congo (specimens deposited in ISNB) have labels stating "ex oothéque Phasmidae ". This record is remarkable in two ways. First, Phasmatidae do not produce oothecae. The hosts may instead be mantids, which do so. Second, all of the numerous specimens are males, suggesting perhaps that this host may not have been optimal in some way.
