Figs 32-35View Figs 28 - 49. — 28 - 31, 75-80View Figs 75 - 80

Buitinga  Kenya 5: Dimitrov, Astrin & Huber 2012 ( DNA sequence data).


Distinguished from known congeners by combination of male cheliceral armature ( Fig. 77View Figs 75 - 80), male palp (shapes of procursus and bulbal process; Figs 75, 76View Figs 75 - 80), color pattern on prosoma and abdomen ( Figs 32- 35View Figs 28 - 49. — 28 - 31), and epigynum with straight scape in anterior position and distinctive posterior structure ( Fig. 78View Figs 75 - 80).


The species is named after the Taita  people (also Wataita  or Wadawida), a Kenyan ethnic group located in the Taita-Taveta District; noun in apposition.

Other material examined


Male (holotype)

MEASUREMENTS. Total body length 3.4, carapace width 1.3. Leg 1: 27.0 (6.8 + 0.5 + 6.5 + 10.4 + 2.8), tibia 2: 4.1, tibia 3: 3.0, tibia 4: 4.0; tibia 1 L/d: 41. Distance PME-PME 185 µm, diameter PME 90 µm, distance PME-ALE 55 µm, no AME.

COLOR. Prosoma pale whitish with black pattern on carapace including ocular area and clypeus, sternum with wide black lateral V-shaped margins, legs ochre-yellow, darker rings on femora (subdistally) and tibiae (proximally and subdistally), tips of femora and tibiae lighter, abdomen pale grey with distinctive black pattern.

BODY. Habitus as in Figs 32-34View Figs 28 - 49. — 28 - 31; ocular area slightly elevated; no thoracic furrow, with small median cone on carapace posteriorly; clypeus unmodified. Chelicerae as in Fig. 77View Figs 75 - 80, with proximal lateral apophyses, pair of small apophyses proximally near median line, and frontal apophyses in relatively proximal position provided with four modified hairs each ( Fig. 80View Figs 75 - 80). Sternum as wide as long (0.65), unmodified.

PALPS. As in Figs 75 and 76View Figs 75 - 80, coxa and trochanter each with retrolatero-ventral apophysis, femur barely modified, trichobothria on tibia very distal, procursus strongly bent back towards femur, distally complex, bulb with simple weakly sclerotized embolus and distinctive pincer-shaped apophysis accompanied by small sclerotized cone.

LEGS. Without spines and curved hairs, few vertical hairs; retrolateral trichobothrium on tibia 1 at 7%; prolateral trichobothrium absent on tibia 1, present on other tibiae; tarsus 1 with ~20 pseudosegments.

VARIATION. The color patterns are very constant but two elements may be less distinct or even missing: the anterior dorsal abdominal mark and the anterior lateral pair of marks on the carapace. Tibia 1 in 35 other males: 5.8-6.9 (mean 6.4).


In general similar to male but ventral abdominal pattern slightly different (anterior paired element shorter, median element longer; Fig. 35View Figs 28 - 49. — 28 - 31), triads closer together (distance PME-PME 140 µm), and carapace without median cone. Tibia 1 in 25 females: 4.5-5.7 (mean 5.2). Epigynum a simple plate with straight scape in anterior position, with distinctive structure posteriorly ( Fig. 78View Figs 75 - 80); internal genitalia as in Fig. 79View Figs 75 - 80, with small pore plates scattered over wide area.


Known from Taita  Hills only ( Fig. 18View Figs 16 - 19).
