Species included. THE fOLLOWINg SPEcIES ARE TRANSfERREd TO Aglaotilla, bASEd ON SPEcIMENS AUTHORITATIVELY IdENTIfIEd bY cOMPARISON WITH THE RELEVANT TYPES OR ON PHOTOgRAPHS Of THE TYPES: A. aeruginosa (SMITH, 1879), comb. nov. ♂ (fROM Mutilla); A. australis (ANdRé, 1898), comb. nov. ♀ (fROM Mutilla); A. discolor BROTHERS, nom. nov. ♀ (= Ephutomorpha aeneidorsis TURNER, 1916, A PRIMARY JUNIOR HOMONYM Of Ephutomorpha lauta VAR. aeneidorsis ANdRé, 1903, dEEMEd AN AVAILAbLE SUbSPEcIfIc NAME UNdER COdE ARTIcLE 45.6.4; ICZN 1999); A. cuprea (ANdRé, 1901), comb. nov., stat. nov. ♂ (fROM Mutilla, AS VAR.

I HAVE NOT SEEN THE TYPES Of OTHER POTENTIAL cONgENERS, OR bEEN AbLE TO RE-EXAMINE SOME OTHERS cRITIcALLY, SO THE AbOVE LIST Of dEScRIbEd SPEcIES IS ALMOST cERTAINLY INcOMPLETE. IN AddITION, I HAVE SEEN SPEcIMENS Of SEVERAL UNdEScRIbEd SPEcIES. IT IS PREMATURE TO ATTEMPT TO PROVIdE A kEY TO THE SPEcIES AT THIS STAgE, SINcE THE NEcESSARY REVISIONARY WORk HAS NOT bEEN dONE. THE gENUS IS PLAcEd IN THE SUbfAMILY SPHAEROPTHALMINAE ANd THE TRIbE DASYMUTILLINI BROTHERS & LELEJ, 2017.
Distribution. AUSTRALIA.
Etymology. LATINISEd fROM GREEk “AgLAOS” = SPLENdId, bRIgHT, bEAUTIfUL, WITH REfERENcE TO THE STRIkINg METALLIc cOLORATION; THE SUffIX - tilla, IS A cOMMON ONE IN MUTILLIdAE, dERIVEd fROM Mutilla.
Remarks. BOTH SEXES Of THIS gENUS ARE PARTIcULARLY cHARAcTERISTIc ANd EASY TO REcOgNISE, THE bOdY bEINg ALMOST ENTIRELY dENSELY ANd dEEPLY PUNcTATE-RETIcULATE, ITS cOLORATION STRONgLY METALLIc ANd JEWEL-LIkE (MESOSOMA OR METASOMA VERY RARELY NON-METALLIc) ANd THE fIRST METASOMAL TERgUM SHORT bUT SUbPETIOLATE ANd POSTERIORLY cONSTRIcTEd WITHOUT ANY PALE INTEgUMENTAL APIcAL bANd. MALES AddITIONALLY HAVE THE NOTAULUS dEEP, ANd THE WINgS ENTIRELY HYALINE ANd ESSENTIALLY cOLOURLESS EXcEPT fOR THE VEINS. FEMALES ARE MOST SIMILAR TO Ephutomorpha ANdRé, 1902, sensu stricto (SEE BROTHERS 2012, fOR WHIcH MALES ARE UNkNOWN), INcLUdINg IN HAVINg THE POSTERO-MEdIAL PALE SETAE ON T2 OfTEN TRANSVERSELY ORIENTEd, ANd THE PYgIdIUM EVENLY cONVEX WITH AN UNdELIMITEd NARROW SMOOTH AREA ALMOST cONcEALEd bY PUbEScENcE, bUT AddITIONALLY dIffER IN HAVINg S2 WITHOUT A WELL dEfINEd TRANSVERSE gROOVE (ALTHOUgH SOMETIMES WITH AN IRREgULAR TRANSVERSE dEPRESSION). FEMALES SEEM TO fALL INTO TWO fAIRLY dISTINcT gROUPS, A SMALLER gROUP WITH THE LEgS LONg ANd SLENdER ANd NO SUbAPIcAL SPINES ON THE MESO- ANd METATIbIAE, ANd A MORE SPEcIOSE gROUP WITH THE LEgS RELATIVELY SHORTER ANd STOUTER ANd A fEW STRONg dORSAL SUbAPIcAL SPINES ON THE MESO- ANd METATIbIAE; A VERY fEW SPEcIES IN THE LATTER gROUP HAVE A SMALL LATERAL fELT LINE ON S2 IN AddITION TO THAT ON T2, AN UNUSUAL SITUATION. MALES ALSO SEEM TO cOMPRISE TWO gROUPS, dIffERINg IN THE fORM Of THE TEgULA, WHETHER APIcALLY EVENLY cONVEX TO TRUNcATE, OR dISTINcTLY EMARgINATE, bUT SEX ASSOcIATIONS ARE TOO fEW TO EVALUATE WHETHER THE gROUPINgS cORRESPONd WITH THOSE Of THE fEMALES. IN AddITION, IN THE MALES THE fORMS Of THE PARAMERES ANd cUSPIdES VARY MARkEdLY, bUT INdEPENdENTLY Of THE TEgULAE.
ALTHOUgH cOLOUR PATTERNS IN bOTH SEXES cAN dIffER STRIkINgLY bETWEEN SPEcIES, THESE cANNOT bE RELIEd UPON AS dEfINITIVE cHARAcTERISTIcS; SPEcIMENS WITH IdENTIcAL cOLORATION, EVEN VERY UNcOMMON PATTERNS SUcH AS MALES WITH dARk PURPLE-bLUE MESOSOMA ANd bRIgHT gOLdEN METASOMA, MAY cLEARLY dIffER MORPHOLOgIcALLY. CONSEqUENTLY, AccURATE IdENTIfIcATION gENERALLY REqUIRES cOMPARISON WITH TYPE SPEcIMENS. (FOR EXAMPLE, TWO Of THE NEW SPEcIES dEScRIbEd IN AN ASSOcIATEd PAPER bY TAYLOR et al. (IN PREP.) WERE INITIALLY IdENTIfIEd AS kNOWN ONES fROM THEIR ORIgINAL dEScRIPTIONS ANd kEYS, bUT cOMPARISON WITH PHOTOgRAPHS Of THE TYPES Of THE SUPPOSEd SPEcIES SHOWEd THAT THOSE IdENTIfIcATIONS WERE ALMOST cERTAINLY INcORREcT.)
THE AbSENcE Of fORE-TARSAL RAkES ANd dEfINEd PYgIdIAL PLATES IN THE fEMALES SUggESTS THAT THEIR HOSTS LIVE ENTIRELY AbOVE gROUNd, ANd dO NOT bURROW IN THE SOIL, AS HAS bEEN fOUNd fOR SOME OTHER MUTILLIdS WITH THOSE cHARAcTERISTIcS (e.g., PITTS & MANLEY 2004, WILLIAMS et al. 2011, BARTHOLOMAY et al. 2015; BAYLISS & BROTHERS 2001 PROVIdEd bIOLOgIcAL INfORMATION fOR SPEcIES Of Dolichomutilla ASHMEAd, 1899, WHIcH ALSO LAck fORE-TARSAL RAkES ANd PYgIdIAL PLATES ANd UTILIzE AS HOSTS VARIOUS WASP SPEcIES WHIcH MAkE MUd NESTS).
