The latitude   and longitudes of those records had been entered in to the WORLDCLIM computer software , which provided estimates of MAT, coldest yearly quarter imply temperature and MAP to a square kilometre amount of spatial resolution.(f) Diagnosis: Titanomyrma lubei Queens separated from other <a href="https://www.medchemexpress.com/Valbenazine.html">NBI-98854 Purity</a> species of Titanomyrma most easily by gaster characters: extra slender, length width: . lubei, nonetheless, these are of similar lengths and maximum widths (figuresand a). Its legs are notably a lot more gracile than these of T. giganteum and somewhat a lot more so than these of T. simillimum. The mandibles are poorly preserved, but appear smaller sized than these with the German species (figuresand a c). Wing length basad the pterostigma in T.DTAsiaArctic OceanWNorth AmericaFigure . Reconstructed early Eocene northern continental positions and shorelines in polar view with Formiciinae fossil localities (G, Germany; B, Britain; W, Wyoming; T, Tennessee), and dispersal routes across the Arctic indicated by red arrows. MAT of your fossil ant localities (table) applied either published proxies for MAT , or new analyses depending on previously published information on the proportion of dicot leaf morphotypes with nontoothed margins working with the leaf margin evaluation equation of Miller et al. , as well as the leaf area evaluation equation for estimating mean annual precipitation (MAP) from Wilf et al. . Occurrence data for contemporary big ants had been gathered from published records and individual communications (electronic supplementary material). The latitude and longitudes of these records have been entered in to the WORLDCLIM computer software , which supplied estimates of MAT, coldest yearly quarter imply temperature and MAP to a square kilometre amount of spatial resolution.(f) Diagnosis: Titanomyrma lubei Queens separated from other species of Titanomyrma most effortlessly by gaster characters: additional slender, length width: . (T. giganteum, .; T. simillimum); middle half roughly cylindrical (others ovate, A widest); A length about a quarter width (other people about a third); A about three occasions A length (other people significantly less than twice); Aabout half as long as wide (others about a third); A not curved around the petiole at joining. (g) Description: Titanomyrma As supplied for Formicium by Lutz , amended here by change in description of gaster (cf. diagnosis, above). (h) Description: Titanomyrma lubei queen As in diagnosis; figuresand a,d; immense size, body approximatelymm extended; head roundedtriangular, approximately . mm   lengthy; approximatelymm wide, about a third alitrunk length; antennae, eyes not recognized; mandibles about a third head length; alitrunk approximatelymm long, wing bearing; legs quick, tibia IIImm; forewing likely in size array of T. giganteum queens; waist single segmented, petiole about . mm wide, lacking anterior peduncle; gastermm long, . mm wide, devoid of constriction among A and also a; spiracles (known on A ) lengthy, narrow. . DISCUSSION (a) The status of formiciine species Titanomyrma is confidently assigned towards the Formiciinae by character states one of a kind inside Formicidae: exceptionally substantial size combined with big, slitlike spiracles , which associate it with T. giganteum and T. simillimum (early middle Eocene Germany: Messel, and cf. these species from Ekfeld Maar [ ]), each transferred here to Titanomyrma from Formicium. Formicium brodiei Westwood, Formicium mirabile Cockerell [ ] (both Bournemouth, UK; middle Eocene) and Formicium berryi Carpenter(middle Eocene Claiborne Formation, Puryear, TN, USA; incorrectly named Wilcox Formation by Carpenter) are only identified from forewings, and were grouped together with the German species by the similarity of their venations.
