J. Longino, 6 Nov 2021: Wilson's species chrysops (Brazil, Pará), midas (Trinidad), perryorum (Brazil, Sao Paulo), and veletis (Bolivia) all look like Forel's rochai (Brazil, Ceará) to me. The measurements overlap, and the images look very similar.

Pheidole rochaiHNS Forel, new status

Pheidole lemur r. rochaiHNS Forel 1912g: 226. Pheidole lemur rochai var. deflexa SantschiHNS 1923d: 46 is a quadrinomial and unavailable.

Types Mus. Hist.. Nat. Geneve.

Etymology Eponymous.

Diagnosis A small yellow member of the diligensHNS group whose major has a moderately prominent mesonotal convexity as part of a bilobous promesonotal outline seen in dorsal-oblique view; short, equilaterally triangular propodeal spine; overall mostly smooth and shiny body with sculpturing on the head confined to the eye level and anterior to it, and composed exclusively of longitudinal carinulae; and abundant medium-length, erect pilosity.

Close to blumenauensisHNS, longiscapaHNS, perryorumHNS, tanyscapaHNS, and vafraHNS, but differing variously in head shape, eye size, sculpturing, and color. See also the less similar lemurHNS, pubiventrisHNS, seeldrayersiHNS, and variegataHNS, as illustrated. Measurements (mm) Lectotype major: HW 0.92, HL 0.96, SL 0.76, EL 0.14, PW 0.56. Paralectotype minor: HW 0.50, HL 0.60, SL 0.74, EL 0.12, PW 0.34. Color Major and minor: concolorous yellow.

Range Known with certainty only from the Ceara type series. I have not seen the series described by Santschi (1923d: 46) as " var. deflexa " from Paraguay.

Biology Unknown.
