          Abstract

          Se recolectó una larva de Liopropoma en post flexión de 18.5 mm, con todos los filamentos de la aleta dorsal, con una red de cuchara en la superficie durante la noche, en el Golfo de California (México). Los filamentos de la segunda y tercera espinas dorsales se observaron inusualmente alargados. La segunda espina midió cerca de diez veces la longitud del cuerpo, con doce hinchazones (o veletas) densamente pigmentadas y conectadas por una sección filamentosa, suave y flexible que tendió a embobinarse, parecida al sifosoma de un sifonóforo. La morfometría de la larva fue similar a la de adultos de L. fasciatum, especialmente la longitud de la cabeza, la longitud del hocico, el ancho interorbital, la longitud del pedúnculo caudal y la longitud de la espina pélvica. La altura del pedúnculo caudal fue similar al de L. longilepis. El espécimen fresco presentó cromatóforos anaranjados sobre la mayor parte del cuerpo. Después de su preservación, se observaron melanóforos sobre el cráneo, la punta de la mandíbula, el ojo y en los filamentos dorsales alargados. Se comparan y discuten otras larvas de Liopropoma.

          Translated abstract

          A postflexion 18.5-mm Liopropoma larva, with entire dorsal fin filaments, was dip-netted at night at the surface in the Gulf of California (Mexico). The second and third dorsal spine filaments were both unusually elongate. The second spine was about ten times the body length, with twelve heavily pigmented swellings or vanes connected by a soft, flexible filamentous section that tends to coil, resembling the siphosome of a siphonophore. Morphometrics of the larva were similar to adult L. fasciatum, especially the head length, snout length, interorbital width, length of the caudal peduncle, and pelvic spine length. The depth of the caudal peduncle was similar to L. longilepis. The fresh specimen had orange chromatophores over most of the body. After preservation, melanophores were present only over the cranium, tip of the lower jaw, the eye, and in the elongated dorsal filaments. Other described Liopropoma larvae are compared and discussed.
