Tetramorium simillimum (F. Smith) View in CoL View at ENA HNS
(Figs 38, 41)
Myrmica simillima F. Smith, 1851: 118 HNS . Syntype workers, Great Britain: England, Dorset (types lost). Tetramorium simillimum (F. Smith) HNS ; Mayr, 1861: 15, 61. [For a statement of current synonymy see Bolton, 1977: 131 with the exception of caldarium (Roger) HNS , for which see above.]
Worker. TL 2.1 - 2.5, HL 0.54 - 0.60, HW 0.48 - 0.54, CI 88 - 93, SL 0.36 - 0.42, SI 74 - 80, PW 0.34 - 0.40, AL 0.58 - 0.68 (45 measured).
Mandibles feebly striate or weakly shagreened, never strongly rugulose, rarely with sculpture almost effaced. Anterior clypeal margin convex and entire, without a median notch or impression. Frontal carinae strongly developed, weakly sinuate, extending back almost to the occiput and outcurved posteriorly, fading out around the posterior borders of the broad but shallow antennal scrobes. Eyes moderate in size, their maximum diameter 0.22 - 0.26 x HW. Occiptial margin of head in full-face view broadly but shallowly concave, the sides of the head broadened behind the eyes, weakly convex, merging into the evenly rounded occipital corners. Propodeum armed with a pair of short, triangular teeth which are usually shorter than the metapleural lobes, the latter broad and roughly triangular in shape. Petiole in profile as in Fig. 38, the node in dorsal view always slightly broader than long, somewhat variable in shape but always broadening posteriorly before narrowing to the postpetiolar junction. Dorsum of head finely longitudinally rugulose, the spaces between the rugulae packed with a fine, dense conspicuous reticulate-punctulation or granulation. Dorsal alitrunk finely, often faintly longitudinally rugulose, the spaces between rugulae densely punctulate. Dorsal petiole and postpetiole similarly but less strongly sculptured, the sculpture sometimes reduced but never completely absent. Gaster unsculptured or with faint granulation on base of first tergite. All dorsal surfaces of head and body with scattered short hairs, generally longer on the gaster then elsewhere. Hairs on alitrunk conspicuous, short, stout and blunt.
Antennal scapes and tibiae only with very short, fine pubescence which is appressed. Colour yellow to yellow brown, often with the gaster darker than the head and alitrunk but some populations uniformly coloured.
