On a small collection of Tetragonicipitidae Lang, 1944 (Copepoda: Harpacticoida) from Mexico: new records and new species

Abstract

At present 151 species/subspecies distributed in 85 genera and 31 families are known from marine and freshwater systems in Mexico. Also, several species belonging to 78 genera and 25 families are yet to be described. Based on previous literature and new samplings, previous studies reported Diagoniceps cf. monodi, Diagoniceps mexicana, Diagoniceps laevis, Godianiceps maya, Odaginiceps cf. elegantissima, Odaginiceps clarkae, Odaginiceps xamaneki, Oniscopsis robinsoni, Phyllopodopsyllus yucatanensis, and Phyllopodopsyllus sp. nov. pauli group. Of these, Diagoniceps cf. monodi from Ensenada del Pabellon (Sinaloa), Godianiceps maya from off Campeche State, and Odaginiceps cf. elegantissima from off Veracruz State and from Ensenada del Pabellon (Sinaloa State) were reported earlier as ‘unpublished’ records. Additionally, an unidentified genus of Tetragonicipitidae, and the genera Odaginiceps and Tetragoniceps from Campeche State, and Phyllopodospsyllus and Laophontella from Campeche and Quintana Roo States were reported. The present contribution aims to formally report the following species found in samples from the Gulf of Mexico, Caribbean sea, Mexican Pacific, Gulf of California, and cenotes from the Yucatan Peninsula: Laophontella horrida dentata Godianiceps maya, Odaginiceps elegantissima, Odaginiceps xamaneki and Phyllopodopsyllus tenuis. Also, the illustrated description of three new species of three genera, Phyllopodopsyllus parastigmosus sp. nov., Tarengoticeps yokotaanensis gen. nov. et sp. nov. and Adoginiceps camaxeni, gen. nov. et sp. nov., are presented.
