Nuconarius Z. Zhao & S. Li, 2018

Li, Bing, Zhao, Zhe, Zhang, Chuntian & Li, Shuqiang, 2018, Nuconarius gen. n. and Hengconarius gen. n., two new genera of Coelotinae (Araneae, Agelenidae) spiders from Southwest China, Zootaxa 4457 (2), pp. 237-263 : 239

Genus Nuconarius Z. Zhao & S. Li gen. n.

Type species. Nuconarius brevipatellatus Z. Zhao & S. Li sp. n.

Etymology. THe GeNeRIC NAMe IS DeRIVeD FROM THe PINYIN WORD "NU", ReFeRRING TO THe NUjIANG RIVeR OF THe LISU AUTONOMOUS PReFeCTURe WHeRe THe GeNUS IS DISTRIBUTeD, AND "- conarius " FROM THe GeNeRIC NAMe Draconarius . THe GeNDeR IS MASCULINe.

Diagnosis. THe NeW GeNUS CAN Be DISTINGUISHeD FROM OTHeR COeLOTINe GeNeRA, exCePT Sinodraconarius ZHAO & LI, 2018, Hengconarius Z. ZHAO & S. LI gen. n., AND Draconarius ; FROM Sinodraconarius BY THe PATeLLAR APOPHYSIS OF PALP WHICH IS NOT BIFURCATe AND AN ePIGYNe WITHOUT A MIDDLe SePTUM; FROM Hengconarius Z. ZHAO & S. LI gen. n. BY THe ReTROLATeRAL TIBIAL APOPHYSIS WITH THRee BRANCHeS, THe LACK OF A LATeRAL TIBIAL APOPHYSIS AND AN ePIGYNe WITHOUT A MIDDLe SePTUM; FROM Draconarius BY THe CYMBIAL FURROW BeING LeSS THAN ½ THe LeNGTH OF CYMBIUM, MeDIAN APOPHYSIS NOT SPOON-SHAPeD OR ABSeNT, ePIGYNAL TeeTH ABSeNT, AND THe SPeRMATHeCAe NOT CONVOLUTeD.

Description. LARGe SIZeD, WITH TOTAL LeNGTHS RANGING FROM 8.70 TO 14.98. CARAPACe BROWN TO TAN; RADIAL ReGION WITH SHORT GReY-BLACK SeTAe; STeRNUM TAN WITH VeRTICAL SeTAe. ABDOMeN TAN TO GReY. CHeLICeRAe WITH 3 PROMARGINAL AND 2 ReTROMARGINAL TeeTH. LeG FORMULA 4> 1> 2> 3. MALe PALP: PATeLLAR APOPHYSIS SMALL AND FIGURe-SHAPeD; ReTROLATeRAL TIBIAL APOPHYSIS WITH THRee BRANCHeS; THe CYMBIAL FURROW SHORT, LeSS THAN ½ THe LeNGTH OF CYMBIUM; eMBOLIC BASe BeGINNING AT 7 TO 8 O’CLOCK POSITION; CONDUCTOR SHORT AND BIFURCATe, WITHOUT THe BASAL LAMeLLA BUT WITH A CONDUCTOR’S DORSAL APOPHYSIS; MeDIAN APOPHYSIS SMALL, NOT SPOON-SHAPeD OR ReDUCeD. EPIGYNe: ePIGYNAL TeeTH ABSeNT; ATRIUM LOCATeD POSTeRIORLY, SLIT-SHAPeD; POSTeRIOR ePIGYNAL SCLeRITe ABSeNT; COPULATORY OPeNINGS LOCATeD CeNTRALLY; COPULATORY DUCT INDISTINCT; SPeRMATHeCAe SIMPLe; SPeRMATHeCAL HeADS LARGe, LOCATeD ANTeRIORLY; SPeRMATHeCAL BASeS SePARATeD.

Natural history. ALL SPeCIeS OF Nuconarius Z. ZHAO & S. LI gen. n. WeRe COLLeCTeD FROM MOIST AND GLOOMY PLACeS IN THe HIGH MOUNTAIN FOReSTS (3113–3710 M).

Composition. SO FAR ONLY THRee SPeCIeS ARe CONSIDeReD IN THe NeW GeNUS: N. brevipatellatus Z. ZHAO & S. LI sp. n., N. capitulatus ( WANG, 2003) comb. n. AND N. pseudocapitulatus ( WANG, 2003) comb. n.

Distribution. TIBeT AND YUNNAN, CHINA ( FIG. 7 ).

Comments. We ANALYZeD THe ReLATIONSHIPS OF COeLOTINe SPIDeRS BY USING 8 GeNeS FROM 286 SPeCIeS IN 19 GeNeRA ( ZHAO & LI 2017). THe MOLeCULAR TOPOLOGIeS SUPPORTeD Nuconarius Z. ZHAO & S. LI gen. n. AS A MONOPHYLeTIC GROUP WHICH IS CLOSeLY ReLATeD TO Hengconarius Z. ZHAO & S. LI gen. n., Sinodraconarius, AND THe FORMeR Draconarius -CLADe: ( Draconarius + ( Hengconarius Z. ZHAO & S. LI gen. n. + ( Nuconarius Z. ZHAO & S. LI gen. n. + Sinodraconarius ))). FOR DeTAILS PLeASe See ZZ935, ZZ978 AND SD015 (SOUTHeRN COeLOTeS GROUPS) IN FIGURe 3 AND SUPPLeMeNTARY FIGUReS S4–S 6 OF ZHAO & LI (2017). ALTOUGH THe FOUR GeNeRA SHARe SOMe COMMON MORPHOLOGICAL CHARACTeRS LIKe THe PReSeNCe OF CONDUCTOR’S DORSAL APOPHYSIS AND THe ATRIUM LOCATeD POSTeRIORLY, Hengconarius Z. ZHAO & S. LI gen. n. CAN STILL Be DISTINGUISHeD eASILY FROM Draconarius AND OTHeR ReLATeD GeNeRA BY THe CHARACTeRS MeNTIONeD ABOVe.
