Tetramorium myops Bolton, 1977 |
Nothing is known about the biology of Tetramorium myops.
Identification
Bolton (1977) - The minute eyes of myops make this species immediately recognizable. In fact, the eyes here are the smallest known for any species outside of the Ethiopian region where at least one species with reduced eyes is known. The affinities of myops lie with Tetramorium inglebyi, but in this latter species the eyes are larger and the anterior portion of the median clypeus is abruptly downcurved.

Description
Worker
Holotype. TL 2.8, HL 0.68, HW 0.62, CI 91, SL 0.48, SI 77, PW 0.44, AL 0.74.
Mandibles striate; anterior clypeal margin impressed medially. Frontal carinae very short, ending in front of the level of the eyes. Eyes themselves minute, consisting of only a single facet, not easily visible in full-face view. Propodeal spines stout, moderately long, slightly upcurved along their length. Metapleural lobes long, triangular and acute, roughly three-quarters as long as the propodeal spines. Peduncle of petiole with a large rounded, convex lamella ventrally, the tergal portion of the node higher than the dorsal length in profile. Base of first gastral tergite strongly concave medially behind the post-petiole, the anterolateral portions of the tergite produced anteriorly, forming a short tooth to either side of the posterior margin of the post-petiole. Dorsum of head with spaced-out, quite distinctive longitudinal rugulae, the dorsal alitrunk similarly sculptured but with some reticulation anteriorly. Petiole with some rugulation on sides and dorsum but post-petiole dorsum mostly smooth. Base of first gastral tergite with vestiges of superficial sculpture, very difficult to see. Dorsal surfaces of head and body with numerous erect or suberect hairs, but those on the scapes and tibiae short and decumbent or subdecumbent. Colour yellowish brown.
Paratypes. As holotype but with range of dimensions: TL 2.6-2.8, HL 0.66-0.68, HW 0.58-0.62, CI 86-91, SL 0.48-0.50, SI 77-83, PW 0.40-0.44, AL 0.70-0.74 (3 measured).
Type Material
