One of the hallmarks of the Cantabrian Lower Magdalenian, along with the presence of the striation-engraved scapulae, is the abundance of antler points or sagaies--azagayas in Spanish--often of quadrangular cross-section and sometimes decorated with complex, incised, geometric or 'tectiform' motifs (Barandiaran, 1967; Utrilla, 1981; Corchon, 1985).
This species is distinctive with the adults having the abdominal ventrites strongly tectiform, with the peak of the ridge carinate on ventrite 5, with ventrite 5 subacute and upturned at the apex as an extension of the carina.
Diagnostic Key to Higher Taxa of New World Tropiduchidae 1.-- Wings shallowly tectiform, usually with Tropiduchinae distinct nodal line (forewings often slightly inflected at nodal line) with venation distinctly reticulate distally; ovipositor flattened laterally, elongated (styletized), gonoplacs usually with distinct marginal teeth; gonapophyses IX in shape of isosceles triangle 1'-- Wings more steeply tectiform, nodal line Elicinae 2 not distinct, forewing venation either not reticulate or entire forewing reticulate; ovipositor rounded, gonoplacs without marginal teeth or with denticles; gonapophyses IX elongate, but not triangular 2.-- Wings steeply tectiform, almost parallel Bucini trib nov.
Pronotum with median carina raised tectiform .............3
Pronotum low tectiform, crossed by three deep sulci; medial carina linear; lateral carinae irregular, wrinkle-like, or partly obliterated; metazona shorter, longer, or equal to prozona, its posterior margin widely obtuse angular.
Emended diagnosis (modified from Puntener et al., 2014): Plesiochelyid with the following autapomorphies: high carapace with a tectiform posterior part; midline keel present, being more distinct posteriorly; second to last neurals relatively wide and hexagonal; posterior neurals wider than long with no short anterior sides.
Elytra elongate, subparallel-sided; humeri distinct; odd intervals clearly tectiform, rather high, with smooth continuous top.
For example, here is "Fracture" (the title poem for Fracture, 1983): The crutch you hand to another is a furious indescribable beast, tectiform of your own shape as Eve staggers out of Eden, the vile legacy in hand, wandering the dust, offering to whoever passes by a rotting piece of it, one peso, by a Mexican roadside, her palm outstretched-- an open heart ceremony announcing that all dark, all light, is the sawing of being on being, a circular coring, a ceremony lit by tapers made of entire kingdoms.
The collection of sagaie fragments is composed almost entirely of round-section pieces, many with single-bevel --often obliquely engraved--bases, one with a longitudinal groove, some with transverse engraved lines on the shaft--but no geometric/ tectiform designs and no square section shafts, features that are typical of the Cantabrian Lower Magdalenian in the following millennium--.
