Fig. 7 in Phylogeny, evolution, and classification of the ant genus Lasius, the tribe Lasiini and the subfamily Formicinae (Hymenoptera: Formicidae)

Fig. 7. Some key features of the major clades of the Lasiini. (A) third abdominal tergite modified with dorsoventrally-oriented groove for reception of entire petiole (Pseudolasius breviceps); black line indicates contour of tergum and black ellipse the spiracle; (B) third abdominal tergite receiving only posterior base of petiole (Myrmecocystus mimicus); white line indicates contour of tergum, and white ellipse the spiracle; (C) frontal protuberance and effaced carinae low relative to face (P. breviceps); (D) frontal protuberance and effaced carinae raised dorsally from face (M. mimicus); (E) metapleural gland atrium grossly enlarged (Lasius subumbratus); black lines show larger size of the metapleural gland bulla (lower indicator) as compared to F, and relative to the propodeal spiracle (upper indicator) and space between the spiracle and bulla (middle portion); (F) metapleural gland atrium small (Lasius turcicus); black lines show smaller size of metapleural gland bulla as compared to E, and relative to the propodeal spiracle and space between spiracle and bulla.
