FIGS 15–16, 20
Type material. Holotype: ♂ (IZCAS-AR33978), FeNGxUe YAKOU (25.972667°N, 98.683933°E, eLeV. 3133 M), PIANMA TOWNSHIP, LUSHUI COUNTY, NUjIANG OF THe LISU AUTONOMOUS PReFeCTURe, Yunnan, China, 25 JUNe 2013, Z. ZHAO & J.C. LIU LeG. Paratype: 1♀ (IZCAS-AR33979), FeNGxUe YAKOU (25.972667°N, 98.683933°E, eLeV. 3133 M), PIANMA TOWNSHIP, LUSHUI COUNTY, NUjIANG OF THe LISU AUTONOMOUS PReFeCTURe, Yunnan, China, 8 DeCeMBeR 2013, Y.

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, 15B); THe eND OF MeDIAN APOPHYSIS BLACK-BROWN AND OPAqUe BUT TRANSLUCeNT IN H. exilis (FIGS 9C, 15C). 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, 16A); 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, 16B).
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).
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).
Variation: TOTAL LeNGTH VARIeS FROM 10.69 TO 12.76.
Distribution. YUNNAN, CHINA (FIG. 20).
