Aenictogiton elongatus Santschi

Type location Zaïre (Santschi, 1919c: 246, illustrated, male) collected at Malela, by Burgeon; .

Santschi's description (1919c, my translation) is at MALE - TL 6-6.5 mm; colour rust, vertex blackish, edge of gaster segments with brownish areas. Shiny; numerous hair pits scattered on the thorax, basal gaster and next segment, almost contiguous on the basal gaster; elsewhere a simple piliferous puncturation. With three long yellowish hairs, fine and recurved on the front (of the head), the sides of the thorax, the petiole lobes, the anterior coxae and the gastral apex. A quite short pilosity (shorter than the ocelli diameter) on the thorax, the petiole and the appendages. Pilosity on the gaster more abundant, straight and inclined at 35°, as long as one-third of the segments.
Head longer than with fossiceps, the eyes very convex occupy the middle half of the sides of the head; behind the sides are parallel. The occipital border is feebly concave. The frontal area has a plain oval area bigger than the ocelli. The scape reaches the posterior third of the eyes. The funiculus is less slender than the scape, segments 3-5 as narrow as long, 4 more slender. Thorax as long as in fossiceps, the sides converging forward of the wing insertions. Metanotum more than three times as long as the scutellum. Petiole a quarter long than the anterior width, the sides weakly concave. The superior edge of the upper posterior lobes extended forwards and converging, to circumscribe a shallow median groove which connects the anterior and posterior concavities. In profile, the petiole dorsum is convex in the anterior half and concave behind. The lobes of the angles are rounded, and the inferior lobe is almost as long as the node and as high as a third of the overall segment height.
Congo (Belgian), Malela, xii.1913 and 1.1914 (L. Burgeon); two male specimens.
Close to emeryi (unknown from life to the author) but with that has finer puncturation and lacks the inferior lobe of the petiole. The wings are missing and the copulatory armature is hidden in the two specimens.
