Diagnosis

Phrenapates latreillei has no supraorbital tubercles, separating it from P. bennettii , P. ohausi , P. gilloglyi Rincon & Smith sp. nov. and P. fortunaensis Rincon & Smith sp. nov. The horn of P. latreillei ( Fig. 3G View Fig ) differs from the unique form of P. dux ( Fig. 3D View Fig ). Phrenapates latreillei (as well as P. educator ) can usually be separated from P. dux (length 27–36 mm) as sizes range from 18–28 mm. The closest species morphologically to P. latreillei is P. educator . Phrenapates latreillei has a horn with a stronger arc than P. educator ( Fig. 3G–H View Fig , respectively). Additionally, there is a tooth on the mandible which is absent in P. educator . The mentum has stronger paramedial ridges and a deeper medial excavation in P. latreillei vs the less sculptured mentum in P. educator . Though not always consistent, the apex of the labrum is often more convex in P. latreillei , whereas it tends to be straight/slightly concave in P. educator .

Redescription

MEASUREMENTS. Length 18–28 mm, width 6–9 mm, specimens measured (n = 20).

HEAD. Medial edge of mandibles with additional tooth, inner margin without crenulation. Galea with cluster of bristles situated near midpoint. Mentum strongly sculptured, apex with medial notch; lateral apices produced. Clypeal apex not dilated. Supraorbital tubercles absent. Clypeal horn strongly arced (in lateral view); gradually tapering to sharp point.

Status

The name Phrenapates latreillei was made available by Lacordaire (1859). A specimen matching his provided locality and description was found in the MNHN. As Lacordaire (1859) did not specify the number of studied specimens, only indicating their plural form, a lectotype designation is needed to stabilize the concept of this species. A specimen of the presumed syntype series from MNHN is here designated as a lectotype (see label data above).

Investigation of the type material and available descriptions revealed that the morphology of Gebien’s (1910) Phrenapates mandibularis is fully in line with the concept of P. latreillei . As such, P. mandibularis is hereby treated as a junior synonym of P. latreillei .
