Type material. Holotype: ♂ (IZCAS-Ar33966), 3 km E of Muruo Village (28.575430°N, 98.038890°E, elev. 3710 m), Zhowagoin Township , Zayü, Tibet, China, 3 September 2014, J. Liu legGoogleMaps  .

Etymology. The specific name is derived from the short male patellar apophysis (Latin prefix "brevi-" (short), noun "patella" and affix "-tus"); adjective.

Diagnosis. Males of this species can be distinguished from N. pseudocapitulatus  by the triangular retrolateral tibial apophysis and the presence of a median apophysis ( Figs 1C View Figure , 5C View Figure ). They can also be distinguished from N. capitulatus  by a shorter patellar apophysis, about ⅓ the length of patellar apophysis in N. capitulatus  ; and the shorter cymbial furrow, about ⅓ the length of cymbium but equal to ½ as in N. capitulatus  ( Figs 1C View Figure , 3C View Figure ). Females of this species can be distinguished from N. capitulatus  by the broader spermathecal bases, the width of bases is subequal to 1½ the width of anterior spermatheca, while it is about ½ in N. capitulatus  ( Figs 2B View Figure , 4B View Figure ). They can also be distinguished from N. pseudocapitulatus  by the extended posterior edge of atrium which covered the middle part of posterior epigynal sclerite, while the posterior epigynal sclerite semicircular uncovered in N. pseudocapitulatus  ( Figs 2A View Figure , 6A View Figure ).

Description. Male (holotype): Total length 11.22. Carapace 5.36 long, 3.83 wide. Abdomen 5.86 long, 3.82 wide. Eye sizes and interdistances: AME 0.14, ALE 0.22, PME 0.18, PLE 0.20; AME–AME 0.07, AME–ALE 0.11, AME–PME 0.18, ALE–PLE 0, PME–PME 0.09, PME–PLE 0.18. Leg measurements: I 17.84 (5.10, 5.34, 4.85, 2.55); II 17.05 (4.83, 5.59, 4.59, 2.04); III 15.79 (4.58, 4.61, 4.32, 2.28); IV 19.37 (5.62, 5.87, 5.34, 2.54). Palp: patellar apophysis short, less than ¼ the length of patella ( Fig. 1C View Figure ); retrolateral tibial apophysis triangular ( Fig. 1C View Figure ); cymbial furrow about ⅓ the length of cymbium ( Fig. 1C View Figure ); embolus beginning at 7:30 to 8 o’clock position ( Fig. 1B View Figure ); median apophysis present, but not spoon-shaped ( Figs 1B–C View Figure ).

Female (one of the paratypes): Total length 12.75. Carapace 5.61 long, 4.08 wide. Abdomen 7.14 long, 4.89 wide. Eye sizes and interdistances: AME 0.13, ALE 0.25, PME 0.18, PLE 0.22; AME–AME 0.10, AME–ALE 0.12, AME–PME 0.31, ALE–PLE 0, PME–PME 0.13, PME–PLE 0.29. Leg measurements: I 14.19 (4.65, 4.65, 3.17, 1.72); II 12.97 (4.15, 4.17, 2.94, 1.71); III 12.23 (4.15, 3.43, 2.94, 1.71); IV 15.44 (4.90, 4.90, 3.92, 1.72). Epigyne: the posterior edge of atrium extended and covered the middle part of posterior epigynal sclerite ( Fig. 2A View Figure ); spermathecal heads large, the width equals the length ( Fig. 2B View Figure ); spermathecal bases wide, as 1½ wide as the anterior spermathecae ( Fig. 2B View Figure ); the distance between spermathecae is less than ½ the width of spermathecal bases in the middle ( Fig. 2B View Figure ).

Variation: Total length varies from 11.22 to 14.98.

Distribution. Tibet, China ( Fig. 7 View Figure ).
