Pheidole fervens |
Antennal scrobe present. Used to distinguish the major worker of Pheidole fervens, Pheidole flavens, Pheidole moerens and Pheidole teneriffana from that of Pheidole obscurithorax. The last species lacks any depression capable of receiving any portion of the antennae. |

Solenopsis xyloni |
The anterior margin of the clypeus has a single median tooth on the midline and a pair of lateral teeth that straddle the midline. Used in Antkey to separate from Solenopsis geminata and Solenopsis xyloni from Solenopsis invicta and Solenopsis richteri. This is arguably the most useful character for separating these species, but it can be difficult to see on some specimens. |
| 5486713 |

Solenopsis xyloni |
The subpetiolar process is well developed as a flange or lobe. The process is located at the far anterior end of the petiole and maybe be difficult to see on most specimens. Used in Antkey to separate Solenopsis xyloni from Solenopsis geminata. |

The promesonotal profile is composed of two, not one, distinct convexities. Used in Antkey to separate Pheidole fervens and Pheidole teneriffana from Pheidole flavens and Pheidole moerens. |
| 5486630 |
bigheaded ant |
Pheidole fervens |
The posterolateral lobes distinctly rugose and the lack of a punctate ground sculpture gives the head a shiny appearance. Used in Antkey to separate the major workers of Pheidole fervens, Pheidole flavens, Pheidole moerens, Pheidole obscurior and Pheidole teneriffana from those of all other Pheidole species. |
| 5486628 |

The lateral portions of petiole and postpetiole are weakly sculptured to lacking sculpture, giving them a shiny appearance. Used in Antkey to separate the minor worker of Pheidole fervens from that of Pheidole obscurithorax. |

The head length is weakly longer than head width. Used in Antkey to separate majors of Pheidole fervens from those of Pheidole teneriffana. |
| 5486625 |
bigheaded ant |
Pheidole fervens |
Posterolateral lobes with longitudinal carinae only occasionally being intersected by much shorter transverse carinae to form a patches of rugoreticulation. This character, combined with the presence of antennal scrobes, is used to separate the major worker of Pheidole fervens and Pheidole teneriffana from that of Pheidole obscurithorax (which has a much denser network of rugoreticulum). |
