T. Kobayashi and T. Hamada 1986 (Bolivicrania) | Cephalon provided with a pair of long genal spines. Glabella
more or less contracted laterally at mid-length, composed of a large subtrigonally ovate unf urrowed main lobe and a pair of relatively small basal lobes ; axial furrows provided with a pair of profound pits in anterior part, isolating basal lobes by their straight posterior extension as far as occipital furrow; small median preoccipital lobe present; eyes and palpebra] lobes fairly large, located posteriorly, embracing basal lobes; marginal rim and furrow narrow; lateral and posterior marginal furrows meeting at genal angle and then running into long genal spine; anterior branches of facial sutures nearly straight and divergent from eyes as far as parallels through eyes and abruptly bent near cephalic margin; their posterior branches nearly diagonal and short behind eyes. Pygidium subtrigonal, a little broader than long and provided with depressed marginal border; lateral margins gently arcuate and confluent with rounded narrow posterior margin; axial lobe nearly as wide as pleural part and multisegmented ; each axial ring divided into a broad convex median part and a pair of small depressed lateral sectants ; a few anterior pleural ribs and furrows running into lateral border. |
