* Panzera (1932) described the larvae of " Helochares griseus " (p. 54) and Helochares lividus (p. 60); " Helochares griseus " is a synonym of Helochares lividus (Forster), with some varieties of " Helochares griseus " synonymized with Helochares obscurus (Müller). This description might correspond to Helochares lividus (Forster) or Helochares obscurus (Müller). ** Peltochares conspicuus has never been reported from Madagascar. The species identification is likely incorrect.SpeciesOriginDescribed stagesReferencesAgraphydrus hanseni (Satô & Yoshitomi) [as Horelophopsis hanseni]JapanThird instar larvaMinoshima et al. 2013Agraphydrus narusei (Satô)JapanFirst and third instar larvaMinoshima and Hayashi 2011Crephelochares nitescens (Fauvel) [as Helochares nitescens or Chasmogenus nitescens]AustraliaEggs, egg case, first and third instar larvae, pupaAnderson 1976; Archangelsky 1997Helobata larvalis (Horn)GuatemalaEgg case, first instar larvaSpangler and Cross 1972; Archangelsky 1997Helochares anchoralis SharpJapanFirst instar larvaMinoshima and Hayashi 2011Helochares clypeatus (Blackburn)AustraliaThird instar larvaWatts 2002Helochares lividus (Forster) [also Helochares griseus (Fabricius)]*Unknown (Palearctic) - ItalyUnknown stage larva in d’Orchymont 1913b; first, second and third instar larvae in Panzera 1932d’Orchymont 1913b; Panzera 1932Helochares luridus (MacLeay)AustraliaThird instar larvaWatts 2002Helochares maculicollis MulsantUSAEggs, first and third instar larvae, pupaRichmond 1920; Archangelsky 1997Helochares nipponicus HebauerJapanFirst, second and third instar larvaeMinoshima and Hayashi 2011Helochares pallens (MacLeay)JapanFirst, second and third instar larvaeMinoshima and Hayashi 2011Helochares tenuistriatus RégimbartAustraliaThird instar larvaWatts 2002Helochares tristis (MacLeay)AustraliaEggs, first, second and third instar larvae, pupaAnderson 1976; Watts 2002Novochares pallipes (Brullé) [as Helochares (s. str.)
