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  BUTAbout 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 BUTAbout 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 BUTAbout 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 ).

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.
