species, subtriangular to drop-like in outline. Flat, triangular planodeltidium with densely striated surface. Hemispondylium made of two subparallel prongs anteriorly ended by two curved pointed edges. Ventral valve floor without median ridge and covered with very rough tubercles except in the gonad pits, which have a smooth surface. Lateral ventral valve floor covered with regular subparallel rows of cuplike tubercles. Cyrtomatodont teeth short, blunt. Lid-like slightly convex dorsal valve with prominent protegulum. Very wide, thick dorsal septum with flat ventral surface. Brachial bridge and peribrachial ridge connected by two posterior outgrowths to the intrabrachial ridge. Calcitic pole variable but generally thick. Intrabrachial ridge oval, regular with smooth margins. Brachial cavities or brood pouches in adults partly covered by radially disposed, irregular spicules leaving a free space between each, rarely cemented together in their anterior part. No real canopies over the brachial cavities are observed in this species.

de petite taille, subtriangulaire ou en forme de goutte. Le planodeltidium est triangulaire, plat avec une surface nettement striée. L’hémispondylium est constitué de branches subparallèles se terminant par un apex pointu recourbé. La surface de la valve ventrale n’a pas de sillon médian et est couverte de tubercules très rugueux et irréguliers à l’exception des cavités où sont situées les gonades. Les flancs internes latéraux de la valve ventrale sont ornementés de séries parallèles de petits tubercules en forme de ventouses. Les dents sont courtes, robustes avec un apex arrondi. La valve dorsale ressemble à un couvercle faiblement convexe avec un protégulum bien individualisé et proéminent. La valve dorsale a un septum très large et épais dont la surface ventrale est plate. Le pont brachial et la crête intrabrachiale sont reliés par de fortes expansions postérieures. Le pôle calcitique est épais. Cavités brachiales partiellement couvertes par des spicules radialement disposées, assez irrégulières et très rarement cimentées entre elles dans la partie intérieure. Les cavités brachiales ne sont jamais totalement couvertes dans cette espèce.

These orifices are small sub-circular rings (Pl. 2, Fig. 1a, 1c) protected by a relatively thick ventral side (Pl. 2, Figs. 1f, 2c). In the posterior part of the valve, two medium-sized lateral visceral gaps are situated between the intrabrachial ridge and the brachial bridge (Pl. 1, Fig. 5a, 5d; Pl. 2, Figs. 1a–b, 2a, 2c). The central posterior visceral gap between the brachial bridge and the intrabrachial ridge is relatively narrow (Pl. 1, Fig. 5e; Pl. 2, Figs. 1d, 2c).

These spicules are of two orders: from the anterior to the middle of the valve the spicules are very thick. From the middle of the valve to the posterior part the spicules are much smaller. There are no spicules along the internal margins of the brachial cavities. However, flanges are developed along the posterior part of the internal margins. The internal side of the peripheral rim has a regular beaded ornamentation. The septum is quite narrow with a concave ventral sulcus. Posteriorly, it is limited by a small circular visceral gap (see

There are no flanges developed along the inner margins of the brachial cavities: the lateral sides of the dorsal septum remain smooth (Pl. 1, Fig. 5a; Pl. 2, Fig. 1a). The internal margin of the peribrachial ridge is not beaded. The septum is much stronger, flat ventrally with a smooth surface and posteriorly it is limited by a larger visceral cavity, which is not circular.

the anterior commissure is rectimarginate. The ventral valve floor is very roughly covered with strong irregular tubercles. The spicules on the brachial cavities are more spaced with a regular size and more radial. There are no flanges along the inner margins of brachial cavities. The septum is wider, thicker and its ventral edge is flat and smooth.

has a high, thin dorsal median septum with an acute posterior tip. Its ventral edge is convex and tuberculate or spinous. The brachial cavities are covered by thin, fragile, irregular canopying spicules that become fused during ontogeny but always leaving random gaps. The canopy apparently never completely covers the brood pouches. In

. Most of the early juvenile stages of growth are quite similar in the different species. In the ventral valve the teeth, the hemispondylium and the flat interarea are immediately developed. In the earliest dorsal valve, the peribrachial ridge, the brachial bridge and the cardinal process are already developed.

, the main steps of the ontogeny described and illustrated in Pl. 3, Figs. 1–5 give a comprehensive view of the development. A peculiar aspect of the ontogeny in this species is the fact that when the intrabrachial ridge is emerging in its posterior part, the dispersed tubercles serving as basement for the construction of the whole intrabrachial ridge are not clearly developed as is the case for other species such as the new species described by Simon

. (2018a). These tubercles are produced at a later stage of growth. At this early stage of growth, they are similar to dispersed nodules (Pl. 3, Fig. 1a–c). However, the septum is already emerging and connected with the base of the initial spikes (Pl. 3, Fig. 1b–c). The calcitic pole is undeveloped. Nonetheless a rudimentary median lobe is already visible on the cardinal process.

They emerge from the base of the brachial bridge as two small pointed nodules (Pl. 3, Fig. 3b).

The calcitic pole and the base of the median lobe of the cardinal process are not fused together (Pl. 3, Fig. 4a).

A remarkable aspect in the ontogeny is the intrabrachial ridge, which is progressively made by erecting separate plates. At the ultimate stage of growth (Pl. 3, Figs. 4a, 5a) these separated plates are fused together.</paragraph>
