Figs 33–38 View FIGURES 33 – 34 View FIGURES 35 – 38 , 39 View FIGURE 39

Type material: Holotype male, 1 female and 5 male paratypes from Shennongjia Nature Reserve (31.5°N, 110.4°E), July 23, 1998 to August 10, 1998, Hubei, China (Hongzhang Zhou, IZCAS).

Etymology: The specific name is taken from the Latin “ strenuus ”, meaning strong and referring to the strong epigynal teeth; adjective.

Diagnosis: The females of this new species are very distinctive and can be easily distinguished from other species of Lineacoelotes gen. nov. Atrium broad, with relatively complicated atrial margins, the bases of epigynal teeth broad, and the spermathecal heads originating anteriorly, extending posteriorly and reaching almost epigastric furrow, then curving back laterally to the anterior side of spermathecae ( Figs 37, 38 View FIGURES 35 – 38 ). The males are similar to those of L. longicephalus sp. nov. in having the spiral distal apophysis at the conductor dorsal edge but the distal apophysis is broad and anteriorly extending ( Figs 33–36 View FIGURES 33 – 34 View FIGURES 35 – 38 ), whereas in L. longicephalus sp. nov. it is narrow and retrolaterally extending ( Figs 13–15 View FIGURES 11 – 13 View FIGURES 14 – 15 ).

Description, male holotype: Total length 6.40. Prosoma 3.20 long, 2.30 wide; opisthosoma 3.20 long, 1.90 wide. Eye measurements: AME 0.11, ALE 0.18, PME 0.15, PLE 0.20; AME-AME 0.10, PME-PME 0.12, PME-PLE 0.10. Chelicera with 3 promarginal and 2 retromarginal teeth. Leg formula: IV, I, II, III; leg measurements: I: 12.4 (3.1 + 4.2 + 3.1 + 2.0); II: 11.1 (2.8 + 3.7 + 2.8 + 1.8); III: 10.4 (2.5 + 3.2 + 3.0 + 1.7); IV: 13.7 (3.0 + 4.4 + 4.2 + 2.1). Palpal patellar apophysis long, with more or less sharp distal end; RTA occupying most of tibial length, with distal end pointed; cymbial furrow less than half of cymbial length; conductor distinctly separated into broad, short ventral apophysis (C1) and strongly modified dorsal edge; in addition to broad, anteriorly spiral distal apophysis (C2) on retrolateral side of conductor dorsal edge, another small, bifurcated, retrolaterally directed apophysis (C3) being situated on conductor dorsal edge; median apophysis spoon-shaped, rounded; embolic base originating more or less proximally and extending distally; embolus moderately long, filiform ( Figs 33–36 View FIGURES 33 – 34 View FIGURES 35 – 38 ).

Female paratype: Prosoma 4.10 long, 2.60 wide. opisthosoma is damaged. Eye measurements: AME 0.13, ALE 0.18, PME 0.15, PLE 0.19; AME-AME 0.08, PME-PME 0.18, PME-PLE 0.18. Chelicera with 3 promarginal and 2 retromarginal teeth. Leg formula: IV, I, II, III; leg measurements: I: 11.0 (3.0 + 3.7 + 2.8 + 1.5); II: 9.6 (2.7 + 3.2 + 2.2 + 1.5); III: 9.0 (2.5 + 2.9 + 2.3 + 1.3); IV: 11.95 (3.2 + 3.85 + 3.3 + 1.6). Epigynal teeth relatively short, separated by their basal width, originating on anterior margin of atrium; atrium large, much more complex than other species of Lineacoelotes gen. nov., separated from epigastric furrow by slight less than its length; epigynal teeth not reaching posterior margin of atrium; atrium extending into epigynum, forming broad copulatory duct; spermathecal heads long, originating distally on spermathecae, extending laterally and posteriorly posterior of spermathecae, close to epigastric furrow, then curving back anteriorly; spermathecae small, oval-shaped, widely separated ( Figs 37, 38 View FIGURES 35 – 38 ).

Distribution: China (Hubei) ( Fig. 39 View FIGURE 39 ).
