Diagnosis
ReferenceDiagnosis
E. V. Syromyatnikova et al. 2013Adocus amtgai can be differentiated from other Adocus species by narrower pleurals 2-4 (width is about 30% of its length) and accordingly wide lateral and posterior marginals, shorter pectorals; marginals overlapping onto costals beginning with marginal 4 (except A. aksary), longer anterior lobe of the plastron (except A. annexus). In addition, it can be differentiated from A. aksary by its relatively longer and wider temporal emargination, transverse prefrontalefrontal suture, more elongated neural 6, trapezoid cervical, wider anterior border of epiplastron and gulars, and shorter extragulars; from A. planus by extension of gulars onto entoplastron; from A. beatus by narrower vertebral 5 and wider inframarginals. See Tables 1 and 2 for a more detailed comparison.
