Nomenclature

 *  angustinodus. Camponotus (Tanaemyrmex) discors var. angustinoda Emery, 1925b: 102 (w.q.) AUSTRALIA. [First available use of Camponotus maculatus subsp. discors var. angustinota Forel, 1907h: 300; unavailable name (Taylor, 1986: 34).]

Description
Worker major. Length 6-9 mm. Smaller and more glossy than the type, similar to gibbinotus. The metanotum (= propodeum) is narrower. Otherwise the shape of the head etc. as with discors. All the same the eyes are somewhat smaller, so I suspect the Uebergange is still like gibbinotos, in which case gibbinotus would become a close relative of the subspecies maculatus. Queen. Length 12mm. Mandibles with 7 teeth, gleaming, externally finely striated, otherwise strongly and coarsely punctated. Head trapeze shaped, long as it is broad, as with the major worker but more strongly punctate, somewhat narrower than the thorax. The basal surface of the metanotum (= propodeum) is much shorter than the declivity. The node has a convex anterior, flat posterior with a sharp convex summit. Wings smoky brown, especially in the cells of the outer edges, on the inner edge and on the base. Ribs and edges bright brown. Above all, the particular sculpture, hair and color as with the major worker. Thorax and head vary between reddish brown and blackish brown, the gaster mostly brown.
