Diagnosis.
The species is very similar to
T. leighi
(
Peckham & Peckham, 1903
)
in the coloration but differs by the location of white hairs on eye field. These hairs form a thin line along the anterior margin of the eye field in
T. leighi
, whereas
T. haddadi
has patches between the anterior eyes (compare
Fig. 200
herein with Wesołowska 2012: fig. 59). The copulatory organs of this species are very similar to those of
T. clarosignata
described above.
T. haddadi
is easily distinguished from
T. clarosignata
by the abdominal pattern (lack of light transverse strip) and the lack of small denticles on the tibial apophysis of the male palp, as well as the placement of the epigynal depressions (lateral in
T. clarosignata versus
anterior in
T. haddadi
) and the broader spermathecae in female.
Etymology.
The species is dedicated to Charles Haddad, an arachnologist from University of the
Free State
of
South Africa
, specialist in African corinnids.
Description.
Measurements (male/female). Cephalothorax: length 1.9–3.1/2.5–2.6, width 1.5–2.3/1.7–2.0, height 0.9–1.1/1.2–1.3. Abdomen: length 1.9–2.7/2.0–2.2, width 1.5–2.0/2.0–2.7. Eye field: length 1.0–1.3/ 1.1–1.3, anterior width 1.5–1.8/1.8–1.9, posterior width 1.4–1.6/1.7–1.8.
Male
. General appearance as in
Fig. 200
. Carapace moderately high, gently sloping posteriorly, brown with darker eye field and lighter patch on foveal area. White hairs form wide streaks on sides and two small rounded patches at fovea (only in some specimens). Anterior eyes surrounded by whitish scales. Eye field with characteristic pattern forming by white hairs; two oblique short streaks between anterior median and lateral eyes and a patch in shape of turned V between anterior medians (
Fig. 200
). Chelicerae with two promarginal teeth and single tooth on retromargin. Endites and labium brown with paler tips, sternum orange brownish. Abdomen ovoid, with wide brown streak medially, sometimes broken into chevrons posteriorly, sides yellowish with small dark irregular patches. Venter light with some darker markings, in darker specimens with broad median brown stripe. Spinnerets yellowish grey. Legs yellowish to brown, femur III with broad dark rings at base and tip (similar rings on femur IV, but poorly contrasting). Long dense blackish hairs on tibia I ventrally. Pedipalps orange with slightly darker distal parts. Tibial apophysis thin, diameter of embolic spiral large, equal breadth of cymbium (
Fig. 201
).
