Platythyrea gracillima Wheeler
Type location Zaïre
(Wheeler, 1922: 59, illustrated, profile and full-face view)
only described (see Bolton, 1995) .
Wheeler described it as:
WORKER - TL 9 mm; very slender, head long and narrow, widest forward of
the small eyes; thorax with nearly straight, horizontal dorsum;
petiole, laterally compressed, twice as long as broad and with markedly
concave posterior face. Slightly shining, mandibles more so, finely and
densely punctate, with a few larger but very shallow and indistinct
punctures on the head, thorax and petiole. Hairs absent, pubescence
yellowish gray, very short and fine. Overall black; appendages and
first gastral segment red; remainder of gaster yellow.
Found in the stomach of a toad.
Brown (1975: 52) noted that the type specimen was TL
10.7 mm, HL 2.20 including the clypeus, HW 1.56, SL 2.46; scape
surpassing occiput by 0.94 mm when held straight back; palp formula
4,4; posterior border of head transverse, straight, except for very
slight median concavity; clypeus convex, anterior border strongly
rounded. He provided the illustration right of the petiole of the type
specimen and described it as a member of a small ill-defined group of
species - all with a gracile (i.e. slender) head and body; long stout
antennal scapes; mesally convex clypeus; slit-shaped propodeal
spiracles; unarmed propodeum; long, narrow petiole node with sharp,
strongly projecting posterodorsal margin. Other members are all from
outside Africa, in Southeast Asia.
