Introduction
The cockroach family Corydiidae Saussure, 1864 (Insecta: Blattodea) is characterized by the presence of an inflated clypeus, which is transversely divided into an anteclypeus and a postclypeus (Fig. 1); the wings, when present, have an anal area with a single fold; finally, there is the presence of two tubercles in the sclerite R2 of the male genitalia (Grandcolas, 1999; Estrada-Álvarez & Guadarrama, 2013). This family has a worldwide distribution and comprises around 260 species grouped in 44 genera (Beccaloni, 2014; Djernaes, 2018). Particularly, North America is home of 65 species which are grouped into eight genera and three subfamilies (Atkinson et al., 1991; Beccaloni, 2014; Estrada-Álvarez, 2013) (Table 1), none of which are of medical or economic significance.

The subfamily Corydiinae is represented in North America by three genera: Homoeogamia Burmeister, 1838; ArenivagaRehn, 1903; and EremoblattaRehn, 1903. The males of these three genera are macropterous (wings which surpass abdominal apex). The females of Arenivaga and Eremoblatta are streamlined and apterous (wingless), with a convex thorax and a sharp pronotum, this is an adaptation for a completely fossorial lifestyle, as it helps them “swim” through loose substrate (Bell et al., 2007). Less adapted “swimmers”, but still completely fossorial, are the females of Homoeogamia, which have tegmina and wings, yet remain flightless. This subfamily has a Holarctic distribution.
The subfamily Latindiinae includes the smallest members of this family, some less than 5 mm in length. The males of MyrmecoblattaMann, 1914 and ParalatindiaSaussure, 1868 are brachypterous (reduced tegmina and wings) (Deyrup & Fisk, 1984; Estrada-Álvarez & Guadarrama, 2013; Mann, 1914; Estrada-Álvarez & Rojas, 2020). Males of CompsodesHebard, 1917 and Latindia Stål, 1860 are macropterous. The females of Myrmecoblatta, Paralatindia, and Compsodes, are apterous; while those of Latindia are macropterous (Estrada-Álvarez & Guadarrama, 2013; Gutiérrez, 2012).
Finally, the subfamily Holocompsinae is represented in the region by the genus Holocompsa Burmeister, 1838; in this genus, both sexes are macropterous and capable of flight, and do not show sexual dimorphism, it is easily separated from the rest by the morphology of their tegmina (Qiu et al., 2020).
Materials and methods
For the making of the key, the works of Choate (2009), Estrada-Álvarez and Guadarrama (2013), Gutiérrez (2012), Hebard (1917a), Helfer (1987), Rehn (1903, 1950), Saussure and Zehntner (1893-1899) and Triplehorn and Johnson (2004) were consulted. The images were obtained from various authors, borrowed from articles (Estrada-Álvarez & Rojas, 2020; Gutiérrez, 2012; Hebard, 1917b; Saussure, 1870), or taken with a SONY α-6000 camera with a SEL30M35 macro lens. All the images were edited using the software GIMP© (Version 2.10).
The type specimens described by Saussure with type locality in Mexico were examined, they are deposited in the collection of the Muséum d'histoire naturelle de Genève, Geneva, Switzerland (MHNG). Other museum specimens were examined: Colección Entomológica (Entomological Research), Metepec, Estado de Mexico, Mexico (CER); Colección Nacional de Insectos, Instituto de Biología, UNAM, Ciudad de Mexico, Mexico (CNIN); Laboratorio de Ecología y Sistemática de Microartrópodos, Facultad de Ciencias, UNAM, Ciudad de Mexico, Mexico (LESM); Instituto de Ecología, Xalapa, Veracruz, Mexico (IEXA); Zoological Collections in the Museum of Biology of Lund University, Lund, Sweden (MZLU).
The checklist of the North American species of the family Corydiidae (Table 1) includes state records for both Mexico and the USA, and are based mainly in the works of Atkinson et al. (1991), Estrada-Álvarez (2013) and Hopkins (2014); other mentions for species of this family in the region were also consulted (Choate, 2009; Deyrup & Fisk, 1984; Estrada-Álvarez & Guadarrama, 2012; 2013; Estrada-Álvarez & Rojas, 2020; Estrada-Álvarez & Sormani, 2021; Hebard, 1917a; 1917b; 1921; Hollier et al., 2020; Mann, 1914; Núñez-Bazán et al., 2021; Peck & Beninger, 1989; Rehn, 1902; 1903; Saussure, 1864; 1870; Saussure & Zehntner, 1893-1894).
Results and discussion
I. Identification key for the subfamilies and genera of Corydiidae of North America
The following key is aimed to help in the identification process of adult specimens of Corydiidae found in Mexico and the USA to the genus level, it will likely fail if juveniles, or female Latindiinae, are examined instead. This key contemplates the taxonomic changes made below.
1 Well-developed tegmina often bearing yellowish-orange spots or bands; the proximal half is sclerotized while the distal half is membranous (Fig. 2) .... HOLOCOMPSINAE: Holocompsa
- Tegmina variable in development, if well-developed, they are completely coriaceous and lack said spots or bands ........................................................................................................................................... 2
2 Large sized species, measuring more than 10 mm in length .................................. CORYDIINAE ….. 3
- Minute species, measuring less than 10 mm in length ............................................. LATINDIINAE ..... 5
3 Pronotum with impressions due to the absence of setae (Fig. 3); both sexes winged (Fig. 3); total length about 30 mm, or more ......................................................................................... Homoeogamia
- Pronotum without said impressions; males macropterous, females apterous; total length 11-20 mm ......................................................................................................................................................................... 4
4 Males with subgenital plate with a spinous process on one side (Fig. 4); females with supra-anal plate not visible in dorsal view .............................................................................................. Eremoblatta
- Males with subgenital plate without said process; females with supra-anal plate visible in dorsal habitus ............................................................................................................................................... Arenivaga
5 Males with diagonal channel in tegmina (Fig. 5) ................................................................................................6
- Males without diagonal channel in tegmina ...................................................................................................... 7
6 Males brachypterous (Fig. 6A) ......................................................................................................... Paralatindia
- Males macropterous (Fig. 6B) ............................................................................................................. Compsodes
7 Males brachypterous (Fig. 6C); body about as wide as long (Fig. 6C); associated with ant’s nests (myrmecophilous) .............................................................................................................. Myrmecoblatta
- Males macropterous (Fig. 6D); body clearly longer than wide (Fig. 6D); not myrmecophilous ................................................................................................................................................................... Latindia
II. Comments and taxonomic changes
Revising the type material of Paralatindia aztecaSaussure, 1868 and Myrmecoblatta hebardiEstrada-Álvarez & Guadarrama, 2013, we conclude that the latter is erroneously assigned to the genus Myrmecoblatta, being more akin with Paralatindia, therefore, it is transferred to this genus, generating Paralatindia hebardi (Estrada-Álvarez & Guadarrama, 2013) comb. nov.
Revising the type material of Latindia mexicanaSaussure, 1868 and Latindia tolteca Saussure & Zehntner, 1893, the synonymy proposed by Hebard, 1917 is confirmed. Furthermore, it is concluded that all the specimens referred by Saussure and deposited in the MHNG are males (contrary to Saussure, 1868, 1870; Saussure & Zehntner, 1893); with the collection and revision of new material, including females, it is confirmed that this species belongs to Compsodes Hebard, 1917: males and females of small size, less than 10mm, with hirsute integument and sexual dimorphism. Males macropterous. Spination type C0 sensuRoth (2003). With conspicuous diagonal channel in tegminas. Pronotum with medial carina. Supra-anal lamina with membranal window and convergent lateral margins and medial emargination. Sub-genital lamina with the projected space between cerci (species self-morphing); genital phalomere on the left side (sclerite L3). Female apterous. Therefore, L. mexicana is retransferred to the genus Compsodes, according to Hebard (1917a), generating Compsodes mexicanus (Saussure, 1868) (♂︎♀︎) comb. rest.
Revising the juvenile holotype of Homoeogamia brasiliana (Saussure, 1864) (MHNG) (Fig. 7), and comparing it with juveniles of Homoeogamia mexicana Burmeister, 1838, it was evident that there is no relation between these two species. When comparing with other juveniles of other Corydiidae of the MHNG, we noted that they were related to Polyphaga Brullé, 1835, especially to Polyphaga aegyptiaca (Linnaeus, 1758); with which we conclude that Polyphaga (Homoeogamia) brasiliana Saussure, 1864 is a JUNIOR SYNONYM of P. aegyptiaca and that the record for Brazil is anthropogenic, and hereby omitted. The records of Homoeogamia sp. n. Bolivar, 1890:137 (Juv.) [Caracas] and Homoeogamia sp. Rehn, 1903: 286 (Juv) [Buenos Ayres, Argentina] should be considered at the level of family: Corydiidae, this same conclusion was reached by Dr. A. B. Gurney (unpublished data).
