Type locality. MEXICO: COAHUILA: Mpio. Acuña: Maderas del Carmen : Los Cojos Ridge, 7000– 7400’ (2134–2256 m), 28°56’21.5’’N 102°36’01.8’’W ( Fig. 3 View FIGURE 3 e–f). Los Cojos Ridge is a high igneous ridge managed by CEMEX-Proyecto El Carmen .
Distribution and phenology. The type series of Neominois carmen suggests that the species occupies a rather extensive range in northeastern Mexico, at least from the Maderas del Carmen in northwestern Coahuila, to the area west of Linares in southern Nuevo León; these areas are separated by about 480 km. It is probable that N. carmen inhabits regions between northern Coahuila and southern Nuevo León, and perhaps even in southwestern Texas, although its overall range remains to be elucidated. Dates of capture of the type specimens indicate a single generation annually, from early June to late July.
Habitat. The Sierra Maderas del Carmen , a sky island with elevations from 600 to 2700 m encircled by low elevational Chihuahuan Desert, represents the major forested portion of the Sierra del Carmen . Its location in northwestern Coahuila, Mexico, is adjacent to the Big Bend region of southern Texas and only 60 km south of Big Bend National Park. The region encompasses a series of biotic associations from desert scrub at lower elevations to mesic montane forest, including Pseudotsuga Carr. and Abies P. Mill. , at the higher elevations ( Jiménez-G & Zuñiga-R 1991). The climate is temperate with average monthly temperatures ranging from 10C in winter to 32C in summer. Annual rainfall varies from negligible at low elevations to perhaps as much as 60 cm at higher elevations, principally from mid-summer to early autumn.
The part of Los Cojos Ridge in the Maderas del Carmen where N. carmen is most abundant is comprised of open areas along a dirt road at the beginning of the pine-oak woodland habitat ( Fig. 3 View FIGURE 3 e–f). This area is dominated by the following plants: Quercus mohriana Buckl. ex Rydb. (Fagaceae) , Pinus cembroides Zucc (Pinaceae) , Juniperus deppeana Steud. (Cupressaceae) , Muhlenbergia emersleyi Va ss e y, Piptochaetium pringlei (Beal) Parodi (both Poaceae ), Lepidium montanum Nutt. (Brassicaceae) , Nolina erumpens (Torr.) S. Wats. , Agave spp. (both Agavaceae ), and Opuntia polyacantha var. polyacantha Haw. (Cataceae) . Other sites in the Maderas del Carmen inhabited by N. carmen include Casa Negro (UTM 734154 x 3203755), 2470m, and Vista Hermosa (UTM 731220 x 3198759), 1398m. The former site, Casa Negro, is at a slightly higher elevation than Los Cojos Ridge, and is dominated by Quercus spp. ( Fagaceae ), Juniperus monosperma (Engelm.) Sarg. , Juniperus flaccida Schltdl. (both Cupressaceae ), Pinus cembroides , Muhlenbergia emersleyi , and Panicum hallii var. hallii Vasey (latter two Poaceae ). The latter site, however, is significantly lower in elevation, at the beginning of the transition zone from low desert to foothill grasslands; Vista Hermosa is dominated by Yucca sp., Dasylirion leiophyllum Engelm. ex Trel. , Agave lechuguilla Torr. (all Agavaceae ), Opuntia engelmannii Salm-Dyck ex Engelm. (Cataceae) , Bouteloua curtipendula (Michx.) Torr. var. caespitosa Gould & Kapadic (Poaceae) , and Viguiera stenoloba Blake (Asteraceae) . The habitat for N. carmen east of San Roberto, Nuevo León, is dominated by “Pinyon pine, Juniper, cactus and grasses” (David Robacker, pers. comm. 2006).
Biogeography. Various authors have discussed biogeographic attributes of taxa occurring in the Sierra del Carmen (e.g., Miller 1955, Encina & Villareal 2002), as well as diverse aspects of their ecology and bioconservation (e.g., Ceballos et al. 1998, Hellgren et al. 2005, McCormack et al. 2005, Villalobos et al. 2005, Bhagabati & Horvath 2006, Poulus et al. 2007). Studies based on birds ( Miller 1955) and oaks ( Encina & Villareal 2002) have reached similar conclusions regarding biogeographic affinities of the faunal elements. While the Sierra del Carmen can be considered an extreme northern geological or biogeographical province of the Sierra Madre Oriental ( Villaseñor & Téllez-Valdés 2004), mesic habitats above 1500m represent a relictual, southern distributional limit for a number of nearctic taxa (including two mammals Sorex milleri Jackson (Soricidae) and Ammospermophilus interpres (Merriam) (Sciuridae) , and subspecies of another mammal Erethizon dorsatum L. ( Erethizontidae ) and a butterfly Limenitis weidemeyerii W. H. Edwards ( Nymphalidae )), and have strong faunal affinities to various Trans-Pecos ranges in western Texas ( Miller 1955, Encina & Villareal 2002) and higher ranges in northern Coahuila (e.g., Sierra de la Madera, Sierra Cruces).
A number of endemic or quasiendemic animals are known from the Sierra del Carmen , including the mammal Scalopus montanus Baker (Talpidae) , subspecies of two additional mammals, Odocoileus virginianus Zimmermann (Cervidae) and Tamias dorsalis Baird (Sciuridae) , and two snakes Natrix erythrogaster (Forster in Bossu) and Coluber constrictor L. (both Colubridae ) ( Kobelkowsky 2003). Encina & Villareal (2002) noted the Sierra del Carmen to be the most diverse region for Quercus in Coahuila, with 16 of 30 species known from the state. Thus, the Sierra del Carmen can be considered a biological island, a component of the “sierras coahuilenses,” which has served various taxa as a relictual distributional outpost.
While the butterfly genera Neominois and Gyrocheilus have been cited as relictual elements of the fauna of the Sierra del Carmen ( Kobelkowsky 2003) , both genera are also distributed far to the southeast in the northwestern Sierra Madre Oriental (data on northeastern Mexican Gyrocheilus will be presented in a subsequent study). The Lepidoptera of the entire region between the known distributional limits of Neominois carmen has been poorly studied, and more endemic taxa could well be found here with continued fieldwork and collections (especially between April and October).
Larval foodplant. Adults of Neominois carmen were found in openings dominated by Piptochaetium pringlei ( Fig. 3 View FIGURE 3 f–h) at both Los Cojos Ridge and Casa Negro. While no oviposition events were witnessed, the close association of adults with this particular grass on Los Cojos Ridge strongly suggests that it is the local larval foodplant. No Piptochaetium was encountered at Vista Hermosa. Neominois was seen only once at this latter locale, indicating a possible stray from higher elevations, but if it breeds in the area around Vista Hermosa, it is possible that the species may use the locally common Bouteloua as a larval foodplant. The early stages are unknown.
Etymology. Neominois carmen is named for the Maderas del Carmen of northwestern Coahuila. This species has been known by the common name Joboni Satyr (see Warren et al. 2008), after Jonás A. Delgadillo Villalobos and Bonnie Reynolds McKinney, who collected part of the type series.
