The clypeatus View in CoL species group
( Figs. 22 View Figure 22 , 23 View Figure 23 )
The clypeatus groupwas proposed byDe Andrade and Baroni Urbani (1999) to include three species from the former genus Zacryptocerus . The authorsstatedthat the diagnostic charactersof this group (triangular vertexal angles, and pronotal and propodeal spines fused by lamella) could indeed be enough to keep them in a separated genus from Cephalotes .However, thiswould render Cephalotes paraphyletic since the phylogeny shows this group as a clade within the genus Cephalotes ( Fig. 54 View Figure54 ). All species in this group are exclusively South American.
Diagnosis: In workers andsoldiers, pronotal andpropodeal spines fused by lamellae ( Fig. 2o View Figure 2 ). Gaster surrounded by a lamella ( Fig. 22 View Figure 22 ).
