Résumé

Echinocephalus scoliodonti n.sp de la valva espiral del pez elasmobranquio, scoliodon sorrakowah (Cuvier) recolectado en Bheemunipatnam (Bahía de Bengala) es descrito. Un examen detallado nos ha permitido constituir una nueva especie de Echinocephalus para incorporar al gusano. Muestra notables diferencias con otras especies conocidas de Echinocephalus en relación a medidas del cuerpo, número y disposición de las papilas caudales, número de filas de espinas cafálicas, ausencia de gubernaculum y presencia de valvas esófago-intestinales. La nueva especie es nominada como Echinocephalus scoliodonti

Résumé

The morphological structures of the advanced third-stage larvae of Gnathostoma spinigerum are reported by using the scanning electron microscope. On the head-bulb, the larva bears two lateral lips, two labial papillae on each lip with an amphid between them. The head-bulb bears four transverse row of well-developed single-pointed hooklets. The number of the hooklets in each row increases posteriorly. The appearance of the hooklets by dorsal view and lateral view is also described. The whole body cuticle is transversely striated and covered with transverse rows of single-pointed spines which are dense on the anterior third of the body and became gradually less both in number and size towards the posterior extremity. The average number of transverse rows of these cuticular striations is 234. A pair of cervical papillae and an excretory pore are located on the anterior third of the body. A pair of body papillae is seen on the posterior half of the body. The subterminal anus is seen in the posterior extremity.
