Etymology.
The specific name is a patronym in honor of the German arachnologist Heiko Metzner, who first labelled the
type
specimens as a new species.
Diagnosis.
Males are similar to those of
Ta. huao
sp. nov.
by the long cymbial dorsal depression, but differ from those by the smaller RTA (
Fig. 23C
). Females differ from all the other species of the genus in having small copulatory openings (
Fig. 23D
).
Description. Male (
holotype
).
Total length: 3.34. Carapace 1.57 long, 1.04 wide, 0.65 high. Ocular quadrangle 1.00 long. Anterior eye row 0.96 wide and posterior 0.92 wide. Chelicera paturon with two promarginal teeth, the distal one tricuspid, and two retromarginal teeth, the proximal one bicuspid and curved. Length of femur: I 1.06, II 0.69, III 0.67, IV 0.84; patella + tibia: I 1.69, II 0.96, III 0.84, IV 1.13; metatarsus + tarsus: I 1.15, II 0.79, III 0.84, IV 0.96. Leg formula: 1423. Leg spination: femur I d1-1-1, p1di, r0; II d1-1-1, p1di, r0; III d1-1-1, p1di, r1di; IV d1-1-1, p1di, r1di; patella I‒IV 0; tibia I p0, r0,

Figs 23A‒23C
): Tibia wider than long; RTA small, triangular; embolus extremely thin and long (720° = 2T); both palps are expanded, but from the cymbial groove, it is possible that the embolus curls retrodorsally over the cymbium (
