A new genus and two new species of Xustrostomatidae Hunt, 2002 (Nematoda: Rhigonematomorpha) from the West Indies

Se describe un nuevo género y dos nuevas especies de xustrostomátidos (Nematoda: Xustrostomatidae) parásitos de diplópodos antillanos. Trachyglossoides jimenoi gen. nov. sp. nov., es muy similar a Trachyglossus Hunt, 2002, pero difiere del mismo por ser el único xustrostomátido con sistema reproductor femenino monodelfo. Este constituye el segundo registro de la familia para Cuba. Zalophora dominicana sp. nov., de República Dominicana es muy similar a Z. repentina García et Morffe, 2010. Se caracteriza por presentar las crestas cefálicas reducidas y el extremo cefálico poco globoso. Este es el primer registro de la familia y el género para el país.

A new genus and two new species of xustrostomatids (Nematoda: Xustrostomatidae) are described parasitizing diplopods from the West Indies. Trachyglossoides jimenoi gen. nov. sp. nov. from Cuba, is similar to Trachyglossus Hunt, 2002. It differs by having the female genital tract monodelphic, feature unique in the family. This constitutes the second record of the family from the country. Zalophora dominicana sp. nov. from the Dominican Republic resembles Z. repentina García & Morffe, 2010. It can be segregate by having a minor development of the cephalic crests and the cephalic end barely inflated. This constitutes the first record of the family and genus for the Dominican Republic.

A new species of Rhigonema Cobb, 1898 (Nematoda: Rhigonematidae) from a Cuban spirobolid millipede (Diplopoda: Spirobolida)

Rhigonema nesoboli sp. nov. (Nematoda: Rhigonematidae) is described from the gut of Nesobolus piedra (Diplopoda: Rhinocricidae) from Eastern Cuba. The new species is character‑ ized by: the body length of both sexes; the cephalic collar umbelliform; the microtricha large, fine, backwardly directed, extending until the first portion of the intestine; the tail compara‑ tively long and subulate in the female and elbowed in the male; the genital tract of Type 4; a number of 19‑21 copulatory papillae arranged as 6‑7 pre-cloacal pairs with a single median adanal papillae and three post-cloacal pairs; and the spicules arcuate and comparatively slen‑ der. It is closer to R. villosum Hunt, 1995, but differs by having a shorter body in both sexes and less copulatory papillae: 19‑21 vs. 27‑31. This is the first Rhigonema recorded for Cuba with a genital tract of Type 4.

A new specie of Artigasia Christie, 1934 (Oxyurida: Hystrignathidae) from a Cuban passalid beetle

Se describe a Artigasia milerai sp. nov. (Oxyurida: Hystrignathidae) parásita de los ciegos intestinales de Passalus interstitialis Escholtz, 1829 (Coleoptera: Passalidae) de Escaleras de Jaruco, provincia La Habana, Cuba (localidad tipo) y El Pan de Matanzas, provincia Matanzas, Cuba. La misma difiere de A. ensicrinata (Hunt, 1981); A. monodelpha (Travassos & Kloss, 1958) and A. pauliani Théodoridès, 1955 por tener los huevos ornamentados con crestas longitudinales y la cola, en proporción, más corta. Además, se diferencia de A. monodelpha y A. pauliani por el esófago, en proporción, más corto, la vulva ligeramente más posterior y la extensión de las espinas cervicales. A. milerai sp. nov. es cercana a A. ankaratrae Van Waerebeke, 1973, pero se diferencia por el cuerpo más robusto, el esófago proporcionalmente más corto y la extensión de las alas laterales.

Artigasia milerai sp. nov. (Oxyurida: Hystrignathidae) is described from the gut caeca of Passalus interstitialis Escholtz, 1829 (Coleoptera: Passalidae) from Escaleras de Jaruco, La Habana province, Cuba (type locality) and El Pan de Matanzas, Matanzas province, Cuba. It differs from A. ensicrinata (Hunt, 1981), A. monodelpha (Travassos & Kloss, 1958) and A. pauliani Théodoridès, 1955 by having ridged eggs and a comparatively shorter tail. It also differs from A. monodelpha and A. pauliani by having a comparatively shorter esophagus, the vulva being slightly more posterior, and the extension of the cervical spines. It is close to A. ankaratrae Van Waerebeke, 1973 but can be differentiated by a stouter body, a comparatively shorter oesophagus and and the extension of the lateral alae.
