Etymology. The species name is a compound word of the Latin prefix sub – and the specific name of Draconarius lutulentus (Wang, Yin, Peng & Xie 1990)  , pointing to the similar conductors of both species; to be interpreted as a noun in apposition.

Diagnosis. This species is similar to D. lutulentus  in having a long conductor and a longitudinally elongated spermathecae, but can be distinguished by the broad patellar apophysis and the broad conductor apex in males, and by the laterally situated epigynal teeth, the widely separated spermathecae, and the small, anteriorly originating spermathecal heads in females.

Description. Holotype male. Total length 7.5, prosoma 4.1 long, 2.7 wide; opisthosoma 3.4 long, 2.0 wide. Eye measurements: AME 0.10; ALE 0.20; PME 0.18; PLE 0.20; AME –AME 0.06; AME –ALE 0.06; PME –PME 0.15; PME –PLE 0.18; clypeus 0.20. Chelicerae with 3 promarginal and 3 retromarginal teeth ( Fig. 28View FIGURES 28 – 33). Leg slender and long, hairy; leg formula: IV, I, II, III; measurements of legs: I: 16.5 (4.2, 5.7, 4.4, 2.2); II: 14.8 (3.8, 4.9, 4.0, 2.1); III: 13.1 (3.4, 4.3, 3.8, 1.6); IV: 17.1 (4.4, 5.5, 5.2, 2.0). PLS with the distal segment longer than the basal one.

Patellar apophysis strong; RTA shorter than tibia, with distal end extending beyond tibia; lateral tibial apophysis absent; cymbial furrow less than half of cymbium length; conductor lamella small; conductor extremely extended basal; dorsal apophysis of conductor small, situated prolaterally; median apophysis rounded; embolus moderately long, arising at approximately 6 –o’clock –position ( Figs 29–31View FIGURES 28 – 33).

Female paratype. Total length 8.2, prosoma 4.0 long, 2.7 wide; opisthosoma 4.2 long, 2.7 wide. Eye measurements: AME 0.15; ALE 0.20; PME 0.20; PLE 0.23; AME –AME 0.12; AME –ALE 0.05; PME –PME 0.12; PME –PLE 0.20; clypeus 0.15. Chelicerae with 3 promarginal and 2 retromarginal teeth. Leg IV formula: IV, I, II, III; measurements of legs: I: 13.6 (3.8, 4.8, 3.4, 1.6); II: 12.0 (3.3, 4.1, 3.1, 1.5); III: 10.0 (3.0, 3.0, 2.8, 1.2); IV: 14.5 (3.7, 4.9, 4.2, 1.7).

Epigynal teeth short, situated on the lateral margin of the atrium; copulatory ducts encircling spermathecae; spermathecae widely separated; spermathecal heads small, originating anteriorly ( Figs 32–33View FIGURES 28 – 33).

Distribution. China (Sichuan) ( Fig. 49View FIGURE 49).
