  Forel (1889) denoted pallescens
as a variety
separable from the type pygmaea on the basis of being bright
yellow to bright light yellow-brown on the posterior gaster. Santschi
(1911i) noted this variety (of pygmaea) could be attached by
its relatively elongated antennae to schmitzi. Emery (1921d)
made a study of the pygmaea group of Mediterranean species;

Records - Santschi (1938a: 39) reported isis workers and
queens from Ghezireh, 23.viii.1923, from nest in millet plant
(Alfieri), possibly the same as atlantis reported by Finzi
(1936); Donisthorpe (1942a) recorded sordida from Siwa, Zeitoun
& Khamissa, 17 workers.
Sharaf list - Material examined: Abu-Madi, Zaranik (North Sinai),
6.v.2003 (3) (SHC); Giza, 20.ii.1955 (4) (ASUC).
El-Ziady (1958) included information that - "Recent
finding (unpublished data) showed that the root aphid Triphidaphis
phaseoli Thoe [(Passerini)?] on bean roots depended on the ants Paratrechina
jaegerskioeldi Mayr and Plagiolepis pallescens Forel for
its transportation and dissemination from plant to plant and from one
crop to another" [El-Ziady, S. 1958. Ants, the probable agents of the
onset of infestation of cotton with aphids and coccids. Bull. Soc.
Ent. Egypt, 62, xx.]
