本文对Veromessor属的10种北美种子收割机蚂蚁进行了分类学修订和生物学综述。提出了两个新的同义词:V.julianus亚种。澄清W.M.惠勒和克里顿1934年新的同义词和V.julianus亚种。manniW.M.Wheeler和Creighton1934年的新同义词在V.julianus(Pergande,1894).描述了一个新物种:假单胞菌新物种(工人,女王,male),由于V.lariversiSmith根据形态和遗传差异分为两个物种。我们还为以下物种诊断了以前未描述的皇后和雄性:V.andrei(雄性),V.chamberlini(女王,male),V.chicoensis(女王,male),V.Julianus(女王,male),和V.stoddardi(女王,male).总结了每个物种的生物学信息,以及分布图和工人钥匙,皇后,和男性。然后我们讨论Veromsor物种的生物学,专注于几种形态和生态性状,这些性状在该属中相对较少的物种(10)中表现出强烈的变异。形态特征包括pH发育程度,适当的脊柱长度,眼睛的大小和结构,工人多态性和工人体型,虽然生态特征包括菌落大小和觅食方法,交配航班的季节性,交配频率,以及女王规模和殖民地建立策略。
This paper provides a taxonomic revision and a
review of the biology for the 10 species of North American seed-harvester
ants in the genus Veromessor. Two new synonomies are proposed: V. julianus subsp. clarior W.M. Wheeler and Creighton 1934 new synonym and V. julianus subsp. manni W.M. Wheeler and Creighton 1934 new synonym are synonomized under V. julianus (Pergande, 1894). One new species is described: V. pseudolariversi new species (worker, queen, male), as a result of splitting V. lariversi Smith into two species based on morphological and genetic differences. We also diagnose previously undescribed queens and males for the following species: V. andrei (male), V. chamberlini (queen, male), V. chicoensis (queen, male), V. julianus (queen, male), and V. stoddardi (queen, male). Information on biology of each species is summarized, along with distribution maps and keys to workers, queens, and males. We then discuss the biology for species of Veromessor, focusing on several morphological and ecological traits that display strong variation across the relatively low number of species (10) in the genus. Morphological traits include degree of psammophore development, propodeal spine length, eye size and structure, and worker polymorphism and worker body size, while ecological traits include colony size and foraging method, seasonality of mating flights, mating frequency, and queen size and colony founding strategy.
