FIGS 1–2 , 7

Draconarius capitulatus WaNG et al. 2010: 24, figs 44–61 (♂ only, ♀ mismatched); Zhu et al. 2017: 242, fIGS 126A–D (♂ ONLY, ♀ mISmaTchEd).

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 LeG . Paratypes: 1♂ 1♀ ( IZCAS-AR 33967 , 33968 ), same data as holotype ; 1♀ (IZCAS-Ar33969), 7 km W of Jumuchang (28.584870°N, 98.123070°E, eLeV. 3680 M), CAWARONG TOWNSHIP, ZAYü, Tibet, China, 6 SePTeMBeR 2014, J. LIU LeG.

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 , 5C ). 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 , 3C ). 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 , 4B ). 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 , 6A ).

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 ); SPeRMATHeCAL HeADS LARGe, THe WIDTH eqUALS THe LeNGTH ( FIG. 2B ); SPeRMATHeCAL BASeS WIDe, AS 1½ WIDe AS THe ANTeRIOR SPeRMATHeCAe ( FIG. 2B ); THe DISTANCe BeTWeeN SPeRMATHeCAe IS LeSS THAN ½ THe WIDTH OF SPeRMATHeCAL BASeS IN THe MIDDLe ( FIG. 2B ).

Variation: TOTAL LeNGTH VARIeS FROM 11.22 TO 14.98.
