Quamtana  Kenya 10: Dimitrov, Astrin & Huber 2012 ( DNA sequence data).

Diagnosis

Distinguished from known congeners by combination of male cheliceral armature ( Fig. 113View Figs 111 - 115), male palp (shapes of procursus and bulbal process; Figs 111, 112View Figs 111 - 115), and absence of AME. The South African Quamtana ciliata ( Lawrence, 1938)  and Q. mbaba Huber, 2003  are similar but both have AME and are much larger (total body length ~3.0).

Etymology

The species name is derived from the type locality; noun in apposition.

Description

Male (holotype)

MEASUREMENTS. Total body length 1.6, carapace width 0.65. Leg 1: 13.0 (3.3 + 0.3 + 3.5 + 4.8 + 1.1), tibia 2: 2.0, tibia 3 missing, tibia 4: 2.0; tibia 1 L/d: 56. Distance PME-PME 175 µm, diameter PME 70 µm, distance PME-ALE 20 µm, no trace of AME.

COLOR. Prosoma pale whitish with wide dark median band on carapace including clypeus but not ocular area, legs pale ochre-yellow, without darker rings, abdomen monochromous pale grey.

BODY. Habitus as in Figs 59 and 60View Figs 50 - 69. — 50 - 52; ocular area barely elevated, each triad on low hump; no thoracic furrow; clypeus unmodified. Chelicerae as in Fig. 113View Figs 111 - 115, with proximal lateral apophyses and distal frontal apophyses provided with two long modified hairs each ( Fig. 114View Figs 111 - 115), without stridulatory ridges. Sternum wider than long (0.48/0.40), unmodified.

PALPS. As in Figs 111 and 112View Figs 111 - 115, coxa unmodified, trochanter with short retrolatero-ventral apophysis, femur barely modified, procursus simple except distally, bulb with T-shaped process and transparent straight embolus arising from bulb next to T-shaped process.

LEGS. Without spines and curved hairs, few vertical hairs (most hairs missing); retrolateral trichobothrium on tibia 1 at 9%; prolateral trichobothrium absent on tibia 1, present on other tibiae; pseudosegments not visible in dissecting microscope.

VARIATION. Tibia 1 in 15 other males: 2.8-3.7 (mean 3.3). In most males, the bulb is rotated out from its normal position (cf. figs 79, 80, 107, 108 in Huber 2003b).

Female

In general similar to male but triads even less elevated and much closer together (distance PME-PME 105 µm). Tibia 1 in 5 females: 2.3-2.5. Epigynum extremely simple externally, unsclerotized ( Fig. 61View Figs 50 - 69. — 50 - 52) with pair of tiny pockets near posterior rim; internal genitalia as in Fig. 115View Figs 111 - 115.

Distribution

Known from several localities in Kenya and Tanzania ( Fig. 25View Figs 24 - 27).
