Messor rugosus (André)

return to key {link to the Hymenoptera Name Server} Type location Israel (Aphaenogaster barbara var rugosa, André, 1881b: 75, worker & male; raised to species Emery, 1908e: 458; illustration in Tohmé & Tohmé, 1981b)
bodenheimeri (Messor rugosus ssp. boenheimeri n. ssp., Menozzi, 1933b: 54, worker) from Israel, Chederah
crawleyi (Messor rugosus André stirps crawleyi Santschi, 1928f: 203, worker) from Egypt, El Faroukia, Mr C W Crawley

{Messor rugosus}André's (1881b) description is at {original description}. Santschi's (1928f) description of crawleyi is at {original description}. Menozzi's (1933b) description of bodenheimeri is at {original description}. Tohmé & Tohmé's notes (1981b) are collated on {original description} (they were wrong in giving Emery (1908e) as having an illustration].

{short description of image}Overall rugosus and aralocaspius (Ruzsky) [type location Russia (Aphaenogaster barbara var aralocaspia (Ruzsky, 1902c: 20, worker; Karavaiev, 1910b: 63, queen & male; Stitz, 1930: 240, queen; raised to species by Pisarski, 1967: 384), subspecies infumatus (Kuznetsov-Ugamsky, 1927a: 91, in key, & 1929d: 19, worker; subspecies status Arnold'i, 1977b: 1642) from Kazakhstan; Bolton, 1995: 252], appear to be closely related. The general consensus (e.g Collingwood, 1985: 248) seems to be that the latter has the first funiculus segment distinctly broader and much longer than the second; that is not reflected in the Karavaiev figures (1910b: 30). The specimens shown below have the first and second funiculus segments of identical lengths and both are quite narrow; aralocaspius also has no teeth of any size on the propodeum. M. rugosus is not among the species reported from Saudi Arabia. The descriptions of rugosus, however, perhaps are confusing as they seem to describe only quite small workers. André (1881b) wrote of them as always small, TL 4-6 mm); the propodeum as unarmed or nearly so (as shown by Thomé & Thomé, 1981b).
