Monomorium niloticum Emery
 Type location Egypt
(Monomorium niloticum n. sp.,
Emery, 1881b: 533, worker; see Santschi,1936a: 37) - see below.

Emery's (1881b) description is at  . Santschi's
(1936a) notes are at  .

 Wheeler & Mann (1916:
170) listed "19. Monomorium venustum
F Smith subsp. niloticum
Emery, Wadi Gazelle (Wadi Ghazala), Sinai Peninsula".
Santschi
(1936a) revived and separated the species as -
Scape surpasses occiput by more than twice its own width; all segments
of funiculus much longer than wide; club quite slender, the middle
segment more than twice as long as it is wide; alitrunk weakly pilose;
mostly yellow but at least gaster dull. His illustrations (right) have
no scale lines. On niloticoides,
he stated the head and gaster shiny. From the photographs of
the types, the shiny form is the type form. Thus, I have separated the dull, distinctly sculptured Monomorium niloticoides as a distinct species.

Collingwood
(1985) distinguished it by - penultimate funiculus segment more than
twice as long as broad, head relatively long, widening anteriorly (CI
75-81); head finely sculptured, unicolorous red with alitrunk,
propodeum with flattened or incavate median area; metanotal groove deep
(in profile a right angle); antennal scape surpassing occiput; ultimate
funiculus segment shorter than combined length of preceding two
segments. He noted - one of the larger Monomorium similar to M.
venustum but generally of a brighter colour and with both head and
antennal segments more elongate.
Globally in salomonis-group with species such as bicolor
and pharaonis (Bolton, 1987). Known from Egypt and Saudi Arabia.
