Hypoponera lea (Santschi)
Type location Sierra
Leone (Ponera lea n. sp., Santschi, 1937g: 73, illustrated,
worker) collected at Njala by E Hargreaves - fragmentary remains at http://www.antweb.org/specimenImages.do?code=casent0915199
junior synonym lepida (Hypoponera
lepida, Bolton & Fisher, 2011: 67, illustrated, worker) from
Juaso, 8.ix.1992, R Belshaw - see below and http://www.antweb.org/specimenImages.do?code=casent0902544
worker only described (new
combination in Hypoponera, Bolton, 1995) .
(1937g) description is at . Santschi's (1938b)
notes are at . It is curious that in a paper where he
defined Hypoponera (see the Genus Introduction) Santschi did
not consider lea as a member of the genus.
As shown below Gabon specimens collected by Yves Braet
from Nigeria match Santschi's description and
drawings in all ways. Bolton & Fisher (2011: 112), who could locate
only a badly damaged holotype, chose to decry Santschi's description. I
quote "In the original (1937) figure there is no mesonotal-mesopleural
suture indicated and the petiole node in profile appears relatively
lower, longer and more broad-topped, generally resembling punctatissima.
In the later (1938) figure, a mesonotal-mesopleural suture is very
conspicuous and the node in profile appears higher, shorter and more
narrowly rounded dorsally, altogether more like dulcis".
The workers I drew and photographed show variation in
the development of the mesonotal-mesopleural suture that satisfies both
Santschi's notes. My drawn specimen, let alone my published
report, was not listed by Bolton & Fisher (2011: 112,
nor under lepida on p 69).
regard H. lepida as a simple
junior synonym of H. lea.

(Taylor, 1976: 21). WORKER. TL 2.46 mm, HL 0.62, HW 0.5, SL 0.47, PW
Colour dark yellow-brown, shiny with relatively dense pilosity. Eyes
small, 2-3 facets. Clypeus with short carina, not ridged in the middle.
Dorsum of propodeum a little longer than the declivity, and with clear
angle at junction (in part after Bernard, 1952).
Occasionally collected on cocoa trees, perhaps tending
Homoptera. Nests in crevices and in ground at the base of trees (e.g.
at the Cocoa Research Institute of Nigeria, Idi Ayunre, Coffee Block
S8, in a dead tree stump).
Also found in Ghana cocoa leaf litter and
nesting in dead wood on the ground at the Mampong Cemetery farm (Room,
1971), this is listed under lepida
by Bolton & Fisher (2011).
