New species of Spauligodon (Nematoda: Pharyngodonidae) in Xenosaurus platyceps (Squamata: Xenosauridae) from Mexico

During a helminthological examination of flathead knob-scaled lizards, Xenosaurus platyceps King and Thompson 1968, from Mexico, 4 of 10 were found to harbor 56 (14 male, 42 female) nematodes of an undescribed species of Spauligodon Skrjabin, Schikhobalova and Lagodovskaja, 1960. The lizard family Xenosauridae is composed of two well-differentiated genera: Shinisaurus in southern China and Xenosaurus in Mexico and Guatemala (Pérez-Ramos et al., 2000). Xenosaurus platyceps is a stocky, medium-sized species endemic to the Mexican state of Tamaulipas where it occurs in dry oak and tropical deciduous forests of the Sierra Madre Oriental (Flores-Villela 1993; Flores-Villela and Gerez, 1994). The ecology of X. platyceps has been studied (Lemos-Espinal, 1997), but, to our knowledge, there are no helminthological reports for it.

A New Species

Dasylirion micropterum is described as a new species from high elevations of the Sierra Madre Oriental in the Mexican state of Coahuila. It differs from known species of Dasylirion for having ascending dark green leaves, narrow inflorescences, small fruits with narrow wings and its distribution restricted to the western side of the Sierra Madre Oriental. The identity of the new species was confirmed through the sequence of matK and rbcL plastid DNA regions. GenBank sequences accessions are included. An illustration, photos and a distribution map are presented for the new species.

A New Species

Beaucarnea olsonii is described and illustrated from tropical deciduous forests of SW Puebla, Mexico. The new species can be distinguished from other Beaucarnea species by its massively swollen base that abruptly tapers into slender branches, by its conspicuously long stigma, and by its pedicel articulation that occurs at 2/3 of the length of the pedicel below the flower. With this new addition, the total number of endemic species of Beaucarnea for Mexico increases to 10, making this country the greatest center of diversification and endemism for the genus. We also provide a distribution map and a conservation status recommendation for the new species, as well as a key to the Beaucarnea species of southern central Mexico.

Eleutherodactylus uno n. sp . is described from the oak-pine zone of the Sierra Madre del Sur, in the Mexican state of Guerrero . The new species cannot be associated with any currently recognized supraspecific division within the genus and demonstrates the unsatisfactory nature of attempts to cluster the approximately 400 known species into groups.

A new flea species, Hystrichopsylla cryptotis, is described from the Sierra Madre Oriental and Sierra Madre del Sur, Mexico. The host of this new species is the shrew Cryptotis mexicana (Coues, 1877) (Mammalia: Soricidae). This flea species is easily recognized by its large size, seven genal combs, and the slender sternum IX, with 13 pairs of thick spiniform setae of different sizes. A key to the Mexican and Guatemalan species of Hystrichopsylla is given. The cladistic analysis indicates that Mexican species of Hystrichopsylla may be arranged in two different species groups: the H. orophila species group (H. orophila Barrera 1952 and H. cryptotis) and the H. dippiei species group (H. dippiei Rotshchild 1902, H. llorentei Ayala and Morales 1990, and H. kris Traub and Johnson 1952). The resolved area cladogram based on their phylogenetic relationships indicates the following relationships: (Sierra Madre Oriental, (Sierra Madre del Sur, Transmexican Volcanic Belt)).

Quercus meavei is described and illustrated as a new species of section Lobatae in the Sierra Madre Oriental. It is compared to Q. albocincta, Q. acutifolia, Q. furfuracea, Q. grahamii, Q. skinneri, Q. uxoris and Q. xalapensis in the Acutifoliae group, which present a biennial pattern of maturation of fruits. Quercus meavei differs from these species in having ovoid to subspherical and glabrate acorns, leaves with a greater number of secondary veins [(12)14–19] impressed adaxially, a crispate leaf margin, long-ovoid buds with golden trichomes towards the apical scales and branchlets usually fulvo-tomentose.

A New Species

Pinguicula simulans (Lentibulariaceae), a new species endemic to Sierra Madre Oriental, is described and illustrated from plants collected at Potrero Redondo, municipality of Santiago, Nuevo Léon, Mexico. Its flowers are similar to those of P. gracilis and the new species therefore belongs to Pinguicula subg. Temnoceras, sect. Microphyllum. It differs from other species in the section by the spatulate winter leaves, which are longer than wide, with a slightly recurved apex. In addition, it is distinguished by the long spatulate, ascendant or diffuse, recurved, summer leaves, which form a loose rosette, and by the calyx that has glandular pubescence on both surfaces.
