The domestic South American camelid Vicugna pacos L. is distributed along Peru, Chile, Bolivia, and Argentina. Here, we contribute to the bioinformatics and evolutionary systematics of the Camelidae by performing high-throughput sequencing analysis on the black Huacaya breed of V. pacos from Puno, Peru. The black Huacaya breed mitogenome is 16,664 base pairs (bp) in length and contains 37 genes (GenBank accession MT044302). The mitogenome shares a high-level of gene synteny to other Camelidae (Camelops, Camelus, Lama, and Vicugna). The mitogenome of the black Huacaya breed of V. pacos situates it in a clade with V. vicugna Molina, sister to Lama. We anticipate that further mitogenome sequencing of different breeds from Vicugna pacos will improve our understanding of the evolutionary history of this taxon.

Gigartinaceae family has been under constant taxonomic changes due to the high morphologic variability of the species. Conventionally its taxonomy has been based in external morphology; nevertheless, recent morphologic studies, supported in molecular studies, have delimited the genus of this family on the basis of cystocarp development and the tetrasporangia. The vegetative and reproductive structures of three common species of the family present in the coast of Peru are described and commented: Chondracanthus chamissoi, Mazzaella denticulata and Chondrus canaliculatus.

La gran variabilidad morfológica de la familia Gigartinaceae ha producido constantes cambios taxonómicos en sus especies miembros. Tradicionalmente su taxonomía ha estado basada en caracteres de la morfología externa; sin embargo, recientes estudios morfológicos, respaldados con trabajos moleculares, han delimitado los géneros en base a al desarrollo del cistocarpo y de los tetrasporangios. El presente trabajo revisa y comenta sobre las estructuras morfológicas vegetativas y reproductivas de tres especies presentes en Perú: Chondracanthus chamissoi, Mazzaella denticulata y Chondrus canaliculatus.
