Etymology:
The specific name is a Latin adjective in apposition, meaning “reverse” and referring to the conductor twisting from ventrally to dorsally and the apophysis on ventral side of conductor twisting from dorsally to ventrally.
Diagnosis:
The female of this new species is similar to
C. guttatus
Wang et al.,
1990
in having a large atrium, the distinct atrial septum, and the epigynal teeth situated close to lateral atrial margins but can be distinguished by the anteriorly and closely situated spermathecal heads and the anteriorly converging spermathecae. The male can be distinguished from the other
Coelotes
species by the long patellar apophysis, the broad conductor and the presence of a small apophysis on ventral side of conductor.
Description:
Male. Total length 9.2–10.1.
Holotype
total length 10.1, prosoma 5.6 long, 3.4 wide; opisthosoma 4.5 long, 3.0 wide. Eye measurements: AME 0.20; ALE 0.25; PME 0.23; PLE 0.23; AME–AME 0.10; AME–ALE 0.08; ALE–PLE 0.08; PME–PME 0.13; PME–PLE 0.23. Clypeus 0.30. Chelicerae with 3 promarginal teeth and 2 retromarginal (
Fig. 8
). Leg IV longest; leg formula: IV, I, II, III; the measurement of legs is as follows: I: 13.9 (3.7 + 4.6 + 3.5 + 2.1); II: 12.2 (3.4 + 4.0 + 3.0 + 1.8); III: 10.1 (2.8 + 3.3 + 2.6 + 1.4); IV: 14.0 (3.8 + 4.6 + 4.0 + 1.6).
Patellar apophysis long, fingerlike; RTA with distal end slightly extended beyond tibia; lateral tibial apophysis distinct; cymbial furrow shorter than half cymbial length; conductor broad, with a small apophysis on ventral side; dorsal apophysis of conductor present; median apophysis broad, spoon–shaped; embolus moderately long, originating prolaterally (

Female.
Total length 12.0. Prosoma 5.5 long, 3.4 wide; opisthosoma 6.5 long, 4.4 wide. Eye measurements: AME 0.18; ALE 0.25; PME 0.23; PLE 0.25; AME–AME 0.15; AME–ALE 0.13; ALE–PLE 0.08; PME–PME 0.15; PME–PLE 0.30. Clypeus 0.35. Chelicerae with 3 promarginal teeth and 2 retromarginal. Leg IV longest; leg formula: IV, I, II, III; the measurement of legs is as follows: I: 11.0 (3.3 + 3.8 + 2.5 + 1.4); II: 9.8 (2.9 + 3.3 + 2.3 + 1.3); III: 8.6 (2.4 + 2.9 + 2.3 + 1.0); IV: 11.8 (3.4 + 4.0 + 3.2 + 1.2).
Epigynal teeth situated near lateral atrial margins, separated by atrium; atrium large, deep, with a distinct septum; copulatory ducts large; spermathecae with the base widely separated and the stalk converged and fused medially; spermathecal head large (
