Resumen
[ES] El estudio de los nematodos de la Sima de la Colada (Hornos, Jaén) ha
revelado la existencia de 25 especies pertenecientes a siete órdenes y 16 familias.
Se han analizado dos tipos de suelo procedentes del interior de la cavidad, uno con
sustrato arenoso, con 15 especies, y otro con guano, con 20 especies. De todos los
órdenes hallados, el orden Rhabditida es el más diversificado, con un total de 11
especies, aunque todas ellas poco abundantes en individuos. Por el contrario, el
orden Mononchida contiene la especie más abundante en las muestras examinadas,
Clarkus papillatus. Las especies encontradas, en su mayoría, son trogloxenas,
siendo propias de hábitats epigeos. Por otro lado, las especies Aulolaimus
autumnalis y Neotylocephalus inflatus (orden Plectida), se citan por primera vez en la
Península Ibérica. De todas las especies se aporta una detallada descripción e
ilustraciones.

Of all the orders found, the order Rhabditida is the most diversified, with a total of 11 species, although all of them are not very abundant in individuals. On the other hand, the order Mononchida present one of the most abundant species in the samples examined, Clarkus papillatus. Mostly, the species found are trogloxenes, being frequent in epigeous habitats. On the other hand, the species Aulolaimus autumnalis and Neotycephalus inflatus (order Plectida), are cited for first time on the Iberian Peninsula.
