The woodlouse spider Dysdera crocata C. L. Koch, native to the Old World, is recorded for the Mexican state of Nuevo León via the revision of vouchered specimens; it is also recorded for the states of Baja California, Guanajuato, Hidalgo, San Luis Potosí, and Zacatecas via the revision of photographic records from the citizen science platform iNaturalist; these represent the first records of the species for said states. A brief diagnosis is provided for the family and the species.

New state records of species of the flat-backed millipede family Paradoxosomatidae (Diplopoda: Polydesmida) are made for Mexico: Akamptogonus novarae (Humbert and Saussure, 1869) is recorded for the state of Nuevo Leon; Asiomorpha coarctata (Saussure, 1860) is recorded for the states of Estado de Mexico, Nuevo Leon, Tamaulipas and Oaxaca; Chondromorpha xanthotricha (Attems, 1898) is recorded for the states of Chiapas, Hidalgo, Nuevo Leon, Tamaulipas and Yucatan; and Oxidus gracilis (C.L. Koch, 1847) is recorded for the states of Coahuila and Tamaulipas. We also present two new cases of predation on Oxidus gracilis from a railroad worm (Coleoptera: Phengodidae) larva and a vinegaroon (Thelyphonida: Thelyphonidae).

Materials and methodsAll the material revised is deposited in the Coleccion Aracnologica of the Facultad de Ciencias Biologicas of the Universidad Autonoma de Nuevo Leon. The prefix of all the samples analyzed is "FCB-AMYGA"; this is the code used in the collection to label all mygalomorph spider samples excluding those in the family Theraphosidae. The samples were analyzed using an AmScope SM-1TSZ stereomicroscope and photographed using an AmScope MU1603 microscope digital camera. All measurements are given in mm. The map in Fig. 4 was created with http:simplemappr.net. The ribs of the disc of the opisthosoma were counted following the method described by Gertsch & Platnick [1975] and Schwendinger [2005]. Taxonomy Family Halonoproctidae Pocock, 1901 Genus Cyclocosmia Ausserer, 1871 NOTES. This genus differs from the rest of halonoproctid trapdoor spiders by having a truncated, ribbed and highly ABSTRACT: This article details new records of the trapdoor spider Cyclocosmia loricata (C.L. Koch, 1842) in Nuevo Leon and Tamaulipas states of northeast Mexico, and refutes previous records of C. truncata (Hentz, 1841) for Nuevo Leon. Insight in the variation in rib counts of the disc of the opisthosoma as well as the first description of the male palp are given.
