Separated here from Pheidole pallidula and Pheidole arenarum

Ruszky's (1905) description orientalis (as pallidula) & arenarum is at . Emery (1915j) gave an illustrated note on orientalis & arenarum, this is at .

Mayr (1880: 38) wrote in his note on "Pheidole pusilla" how he regarded P. pallidula as known from southern Europe and Algeria, whereas P. pusilla was cosmopolitan into the south European peninsulas, with soldiers that had long propodeal spines being P. pusilla; the note is at .

Emery (1915j: 229) emphasised that the type form was not found in Asia, and Ruszky was wrong, what Ruszky described as pallidula was an undescribed form. Emery called that orientalis and regarded it as very close to the Ruszky subspecies arenarum. He noted also the identity of "Pheidole pusilla" of Mayr (1877, 1880, Fedtschenko voyage to Turkestan) and megacephalo-pallidula of Emery & Forel (1979) were probably of this eastern form. Emery had not seen those reported from Egypt or from the Balkans.

Emery (1915j) noted the minor of arenarum and its variety orientalis had the head widely truncate posteriorly, with more rounded posterior angles; the scape surpassed the occipital border by one-third of its own length, e.g. much more than in the type form minor. The pedicel was like the type but sometimes the propodeal spines were longer. Dark brown or chestnut brown; the major head was lighter, brownish yellow-red. On orientalis he drew attention to the sides of the head being more cuvred than in arenarum,
Specimens from the "Orient" were all or the "plus claire" paler orientalis variety. He reported specimens sent to him from the Adriatic are by Dr K Wolf, where the paler type form was found in the northern Trieste area but specimens from the southern Umago and Rovigno were all of the dark orientalis variety
