Ecology and distribution. Tadzocrangonyx alaicus , sp. n. WAS FOUnD OnLY In THE PAmIR-ALAY mOUnTAIn SYSTEm, AT ELEVATIOn 1155 m A.S.L. OF THE nORTHERn FOOTHILLS OF THE ALAI RAnGE In A KARST SPRInG LOcATED In THE SHAKHImARDAn RIVER bASIn.

Remarks. AccORDInG TO mOLEcULAR AnALYSIS THIS AmPHIPOD bELOnGS TO GAmmARIDAE , AS THE mOST bASAL bRAncH OF THE Sarothrogammarus GROUP OF GEnERA (SKET & HOU, 2018). THE Sarothrogammarus GROUP HAS A DISjUncT DISTRIbUTIOn bETWEEn PAmIR PLATEAU FRESHWATERS AnD MEDITERRAnEAn SHORES; WHILE THE GEnUS Tadzocrangonyx IS LImITED TO CEnTRAL ASIA. THESE DISTRIbUTIOn PATTERnS mIGHT bE DRIVEn bY THE TETHYAn RETREAT (HOU ET AL., 2014). ALTHOUGH OF A cRAnGOnYcTID SHAPE, IT DIFFERS FROm cRAnGOnYcTIDS bY THE AbSEncE OF STERnAL GILLS AS WELL AS bY A DEEPLY SPLIT, nOn-cRAnGOnYcTID TELSOn . SIncE WE HAVE nO mOLEcULAR DATA AbOUT bOTH PREVIOUSLY DEScRIbED Tadzocrangonyx SPEcIES, THE TYPE T. schizurus ( BIRšTEjn, 1948) AnD T. setiferus (BIRSTEIn ET LjOVUScHKIn, 1972), OUR TAXOnOmIc DEcISIOn IS SUPPORTED bY GEOGRAPHIcAL POSITIOn bETWEEn bOTH AS WELL AS bY mORPHOLOGIcAL SImILARITY OF THREE SPEcIES.

THE mOST DISTURbInG cHARAcTER IS A WELL DEVELOPED TERmInAL ARTIcLE OF THE UROPOD III EXOPODITE, WHIcH IS mISSInG

AT bOTH PREVIOUS SPEcIES. HOWEVER, THIS IS nOT A PHYLOGEnETIcALLY STAbLE cHARAcTER. In THE RELATED GEnUS

Sarothrogammarus View in CoL , THIS ARTIcLE mAY bE TWIcE THE LEnGTH OF SURROUnDInG SPInES In ATLAnTIc AnD MEDITERRAnEAn RELATIVES ( STOcK 1971), OR mORE THAn HALF SHORTER AnD nOT THIcKER THAn SURROUnDInG SPInES (In S. ruffoi View in CoL KARAmAn, 1971), OR EVEn 'nOT VISIbLE (REDUcED)' (In S. asiaticus View in CoL MARTYnOV, 1935). In THE LESS RELATED GEnUS Niphargus View in CoL ScHIöDTE (FAm. NIPHARGIDAE View in CoL ) THIS ARTIcLE mAY bE OF THE SAmE LEnGTH AS THE PROXImAL ARTIcLE, OR mUcH SHORTER, OR EVEn AbSEnT (In N. buturovici View in CoL S. KARAmAn, 1958). IT IS AbSEnT ALSO In Haploginglymus View in CoL SPP. WHIcH APPEARED TO bE mOLEcULARLY nESTED WITHIn Niphargus View in CoL (SEE ALSO MOšKRIč, 2016). THUS, THE DIFFEREncE In THE UROPOD III DOES nOT PREVEnT THE nEW TAXOn OF bEInG A mEmbER OF THE SAmE PHYLOGEnETIc bRAncH, OF THE Sarothrogammarus View in CoL GROUP AnD OF THE GEnUS Tadzocrangonyx View in CoL .

THE SYSTEmATIcS OF THE CEnTRAL ASIAn SAROTHROGAmmARIDS, Sarothrogammarus View in CoL , Comatogammarus View in CoL , Barnardiorum View in CoL AnD Tadzocrangonyx View in CoL IS RATHER POORLY DEVELOPED AnD THEIR TAXOnOmIc RELATIOnSHIP IS cOnTROVERSIAL. NEVERTHELESS, In THE cOURSE OF THE cOmPARATIVE mORPHOLOGIcAL AnALYSIS WE DEcIDED THAT THE SUITE OF mORPHOLOGIcAL cHARAcTERS OF THE nEW SPEcIES mOST RESEmbLES Tadzocrangonyx View in CoL (SEE KARAmAn & BARnARD 1979). TWO PREVIOUSLY DEScRIbED SPEcIES OF THE GEnUS Tadzocrangonyx View in CoL KnOWn FROm THE CEnTRAL ASIA ARE RATHER DIFFEREnT FROm EAcH OTHER, ESSEnTIALLY DIFFERInG PRImARILY In THE STRUcTURE OF THE UROPOD III. BOTH SPEcIES SIGnIFIcAnTLY DIFFER bY ARmATURE OF bOTH GnATHOPODS AnD bY A SPEcIAL SHAPE OF TELSOn In T. alaicus View in CoL , sp. n. (SEE TAbLE 1). MAXILLA II IS ALSO VERY DIFFEREnT WITH A VERY nARROW InnER PLATE. HOWEVER, FOR A nUmbER OF SIGnIFIcAnT FEATURES WE cOnSIDER THE nEW SPEcIES cLEARLY RELATES TO THE GEnUS Tadzocrangonyx View in CoL : I.E., SHORTEnED cOXAL PLATES I–IV, SUb-SYmmETRIcAL PALPS OF mAXILLA I, STRUcTURE OF GnATHOPODS (PALm nOT ObLIqUE), UnmODIFIED PEREOPODS III AnD IV (SEE ALSO STOcK 1971). Tadzocrangonyx alaicus View in CoL , sp. n. IS SIGnIFIcAnTLY DIFFEREnT FROm THE KnOWn SPEcIES OF Tadzocrangonyx View in CoL AnD OTHER SAROTHROGAmmARIDS bY A qUITE UnIqUE STRUcTURE OF UROPOD III WITH THE RELATIVELY WELL DEVELOPED TERmInAL SEGmEnT OF THE EXOPODITE. WE mAY SUPPOSE THAT Tadzocrangonyx View in CoL REPRESEnTS A STYGObIOTIc RELATIVE OF A mUcH DIVERSIFIED Sarothrogammarus View in CoL -GROUP In THE REGIOn.
