The umbraculatus View in CoL species group
( Fig. 53 View Figure 53 )
The monotypicumbraculatus group was created by Kempf (1958a). He discussed the position of the species, which shares characters with the angustus and pinelii groups, but is different enough to be separated from them. Kempf’s proposal was corroborated by the morphological and molecular phylogenies (De Andrade and Baroni-Urbani, 1999, see their Fig. 24 View Figure 24 ; Priceet al., 2014, 2016, see their Fig. S3 View Figure 3 ), both phylogenies recover this species as a monophyletic lineage. The recent molecular phylogenies byPrice et al. (2014, 2016) recovered umbraculatus as a sister group of the clade formed by the angustus , fiebrigi and prodigiosus groups ( Fig. 54 View Figure54 ). Cephalotes umbraculatus is broadly distributed in Central America and north of South America.
Diagnosis: In workers, body with appressed hairs. Dorsal and declivous face of propodeum continuous, not meeting in a distinct propodeal angle, with a variable number of spines. Dorsum of petiole without denticles. Gaster yellowish with a cross-shaped dark macula, anteriorly with lamellarexpansions ( Fig. 2p View Figure 2 ). In soldiers, in dorsal view, pronotum crest with pointed edges ( Fig. 3f View Figure 3 ).
