Spermophora Ken  39: Dimitrov, Astrin & Huber 2012 ( DNA sequence data).

Diagnosis

Distinguished from very similar S. maathaiae  sp. nov. by shape of female epigynal scape (longer; tip pointed; Fig. 90View Figs 87 - 91) and by details of procursus tip (slightly different shapes of sclerites; Figs 87, 88View Figs 87 - 91). From other species by male cheliceral armature (shapes of frontal apophyses; Fig. 89View Figs 87 - 91) and by pointed tip of female epigynal scape.

Etymology

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

Description

Male (holotype)

MEASUREMENTS. Total body length 3.6, carapace width 1.3. Leg 1: 20.4 (5.2 + 0.5 + 5.1 + 6.9 + 2.7), tibia 2: 3.3, tibia 3: 2.6, tibia 4: 3.4; tibia 1 L/d: 41. Distance PME-PME 175 µm, diameter PME 125 µm, distance PME-ALE 55 µm, no AME.

COLOR. Prosoma ochre-yellow with large lateral black marks and Y-mark behind ocular area, ocular area laterally darkened, clypeus with pair of darker smudges below eye triads, sternum monochromous black, legs ochre-yellow, with darker rings on femora (subdistally) and tibiae (proximally, subdistally), abdomen grey with distinctive black pattern dorsally and laterally, ventrally mostly black.

BODY. Habitus as in Figs 40 and 41View Figs 28 - 49. — 28 - 31; ocular area elevated, with pair of horns between triads ( Fig. 44View Figs 28 - 49. — 28 - 31); carapace only anteriorly with shallow thoracic furrow; clypeus unmodified. Chelicerae as in Fig. 89View Figs 87 - 91, each frontal apophysis forming a cup-shaped depression, without modified hairs. Sternum wider than long (0.94/0.72), unmodified.

PALPS. As in Figs 87 and 88View Figs 87 - 91, coxa with retrolatero-ventral apophysis, trochanter with retrolateral apophysis, femur barely modified (except dorsal apophysis proximally), procursus with ventral flap and several complex distal elements that appear hinged to proximal part, distinctive spine-like process visible in retrolateral view, bulb with three cone-shaped projections and long embolus.

LEGS. Without spines and curved hairs, few vertical hairs; retrolateral trichobothrium on tibia 1 at 10%; prolateral trichobothrium absent on tibia 1, present on other tibiae; tarsus 1 with>30 pseudosegments, distinct distally.

VARIATION. Tibia 1 in 3 other males: 4.8, 4.9, 5.3.

Female

In general similar to male but triads closer together (distance PME-PME 135 µm), without horns. Tibia 1 in 6 females: 4.2-4.4. Epigynum a simple plate with long posterior scape ending in scorpion-tail-like tip ( Fig. 90View Figs 87 - 91); internal genitalia as in Fig. 91View Figs 87 - 91.

Distribution

Known from type locality only ( Fig. 27View Figs 24 - 27).
