Minibiotus furcatus

About Minibiotus furcatus

Minibiotus furcatus is preserved as reported in Meyer’s 2015 Oceania account, with the Kauaʻi source evidence dated 2011 and based on moss/lichen collection and microscopy. This is a historical source record. The plate does not establish current presence, abundance, island-wide distribution or resolved native status, and it does not identify a new Kauaʻi voucher.

The image is a disclosed reconstruction of the published nominal adult diagnosis. Claxton’s 1998 revision describes yellow body cells beneath a smooth cuticle bearing rows of variably shaped pores, a long ventral reinforcing bar and macroplacoid row, a small indistinct microplacoid and long slender claws with short high accessory points. The adult has the tardigrade arrangement of four bilateral pairs of legs. Comparative material discussed by Meyer and colleagues in 2011 distinguishes its small, mostly trefoil pores from the larger polygonal pores attributed there to Minibiotus jonesorum. Stec and colleagues’ 2021 study supports the Minibiotus combination and describes the peribuccal structures as reduced, shortened and thickened lamellae. The natural moss/lichen water-film scene is illustrative rather than a documented Kauaʻi photograph.

The reconstruction is guided by named published adult descriptions; a complete modern type habitus image was not recovered for this repair. Claxton’s furcatus account examined no new material. Published comparisons differ on fine hind-claw lunule and leg-granulation details, which remain unadjudicated and are not enlarged or presented as resolved diagnostic decoration. Buccal apparatus measurements, placoid arrangement, eggs and microscopic claw characters require specimen study; the ecological illustration cannot certify them. Recent Minibiotus phylogenetic work also cautions that material sequenced under furcatus by different authors can represent different species. The historical Kauaʻi taxon concept therefore remains open and explicitly unverified.
