Etymology. The specific name is derived from the long male palp (Latin prefix "longus-" (long), noun "palp" and affix "-us"); adjective.

Diagnosis. The males are similar to H. exilis  but differ by the short and horizontal conductor while in H. exilis  , the end of conductor slightly upward ( Figs 9B View Figure , 15B View Figure ); the end of median apophysis black-brown and opaque but translucent in H. exilis  ( Figs 9C View Figure , 15C View Figure ). The females can be easily distinguished from H. exilis  by the large posterior epigynal sclerite; the height of posterior epigynal sclerite subequal to ⅓ the height of epigyne, while it is twice in H. exilis  ( Figs 10A View Figure , 16A View Figure ); the broad spermathecal heads, whose width equals to the length but in H. exilis  , the length of spermathecal heads is longer than the width and fertilization duct thin ( Figs 10B View Figure , 16B View Figure ).

Description. Male (holotype): Total length 10.76. Carapace 5.74 long, 4.25 wide. Abdomen 5.02 long, 3.51 wide. Eye sizes and interdistances: AME 0.13, ALE 0.25, PME 0.23, PLE 0.24; AME–AME 0.08, AME–ALE 0.05, AME–PME 0.15, ALE–PLE 0, PME–PME 0.15, PME–PLE 0.15. Leg measurements: I 29.07 (8.42, 8.15, 7.91, 4.59); II 27.04 (7.91, 7.65, 7.14, 4.34); III 25.50 (7.65, 6.88, 6.89, 4.08); IV 29.57 (8.93, 7.65, 8.41, 4.58). Palp: patellar apophysis absent; RTA square slice-shaped; LTA short, approximately ⅓ the length of RTA; cymbial furrow short, less than ½ the length of cymbium; embolus beginning at 8 o’clock position; conductor short, bifurcate and horizontal; median apophysis thin and slice-shaped ( Figs 15A–C View Figure ).

Female (paratype): Total length 10.69. Carapace 5.61 long, 3.31 wide. Abdomen 5.08 long, 3.29 wide. Eye sizes and interdistances: AME 0.13, ALE 0.24, PME 0.21, PLE 0.25; AME–AME 0.10, AME–ALE 0.08, AME– PME 0.14, ALE–PLE 0, PME–PME 0.13, PME–PLE 0.14. Leg measurements: I 17.07 (5.62, 5.09, 3.82, 2.54); II 16.29 (5.61, 4.58, 3.82, 2.28); III 14.52 (4.85, 4.07, 3.56, 2.04); IV 18.34 (6.12, 5.09, 4.84, 2.29). Epigyne: middle septum extends to the posterior edge of epigyne; anterior epigyne weakly sclerited, with lightly wrinkles, the height of it about ½ the epigynal height; the height of posterior epigynal sclerotized is more than ⅓ the epigynal height; atrium trajectile, occupying about ¼ of epigynal plate; spermathecae simple and separated, the distance between the anterior spermathecae is twice the spermathecal diameters; the width of spermathecae about ¾ the length; spermathecal heads situated anterolaterally ( Figs 16A–B View Figure ).

Variation: Total length varies from 10.69 to 12.76.

Distribution. Yunnan, China ( Fig. 20 View Figure ).
