Pseudomops septentrionalis Hebard, 1917

( Figs. 1 A-1J)

Diagnosis. Small species (12-19.75 mm); related with P. interceptus head red, orange, or dark brown (completely black in P. guerinianus , P. nigrimaculis and P. cinctus ), sexual dimorphism in the antennas absent, both sexes with slightly hirsute antenna and annulli posterior to the hirsute third (sexual dimorphism in the antennas present in P. guerinianus and P. cinctus ) and the morphology of the abdomen, laminae and male genitalia. P. septentrionalis differs from P. interceptus the structure of the tergal glands, tufts of piliform bristles only in T-3 and T-4 ( Fig. 1G ) ( Roth 1969), styles and sclerites of the male genitalia and valvar complex in females ( McKittrick 1964). Phenotypically this species is the only one present in Mexico and the United States with a pronotum with a rufus disc and yellowish border and anterior margin with diffuse blackish macula.

It is described based on material collected in Texas (male and female Brownsville, Cameron County, Texas, type locality) and Mexico (Saltillo, Coahuila; San Jose and Tamaulipas, females paratypes) ( Hebard 1917). Subsequent years, new records were made within Mexican territory for the states of Jalisco: Tuxpan, Tuxpan. Sinaloa: Mazatlán, El Venadillo. San Luis Potosí: caves (without more data). Tamaulipas: Gómez FarÍas, San José; Matamoros, Heroica Matamoros; Jaumave, Sótano de la Joya de Salas en la Sierra Guatemala. Caves (without more data) ( Rehn 1904; Hebard 1917, 1921, 1922 [1923], 1932, 1942 [1943]; Princis 1969; Reddell & Mitchell 1971; Reddell 1981; Atkinson et al. 1991; Estrada-Álvarez 2013; Palacios-Vargas et al. 2015).

In the USA P. septentrionalis occurs in Alabama, Arkansas, Louisiana, Mississippi, Oklahoma, and Texas ( Hebard 1917, 1942 [1943]; Atkinson et al. 1991; Roulston & Appel 1997; Schiff & Schiefer 1999; Gaspar et al. 2015).

Notes. 1) The record to Panama in Fisk (1971), they are misidentification, belong to P. interceptus . 2) The record in Estrada-Álvarez & Guadarrama (2013) and Estrada-Álvarez (2013), they are misidentification, belong to P. interceptus (material revised).

Material examined. Nuevo León, Mexico (18: 15 males, 3 females) : 10 males, 2 females from Nuevo León, Cascadas de Guadalupe , Cerro de la Silla; 25°37’46.3”N, 100°12’36.3”W; 27.IV.2021; Jorge J. RodrÍguez-Rojas coll. ( CER) . 5 males, 1 female same data; 27. V .2021 ( CER) .

Pseudomops septentrionalis Hebard, 1917 is distributed from the USA to Mexico. In Mexico there are few records in the literature ( Hebard 1917; Atkinson et al. 1991). Published reports mention the presence of in Coahuila, San Luis Potosi, Jalisco, Sinaloa, and Tamaulipas ( Hebard 1917, 1921; Atkinson et al. 1991). But in the iNaturalist platform, 89 photo records have been observed in Mexico from 2013 to 2021. It is present in the states of Chihuahua, Sinaloa, Nuevo León, Tamaulipas, Zacatecas, San Luis PotosÍ, Queretaro, State of Mexico and Veracruz. With these photo records, the distribution of P. septentrionalis is wider, and it is along the Sierra Madre Oriental and Sierra Madre Occidental in Mexico.

In the present work, we captured and reviewed 18 specimens, which are reported for the first time in the state of Nuevo León. These records were found in the Cascadas de Guadalupe, Cerro de la Silla, Nuevo León. These were found perched on the rock at night, between 21:15 and 21:40 h. On the iNaturalist platform, there are seven photo records in this area. Five of them are perched on a plant leaf during the day, and two on the rock at night.

Also, the 69 photo records documented in the iNaturalist platform show a distribution through the Sierra Madre Oriental in Nuevo León, and the records outside the conserved areas are close to the rivers, thus it apparently has a displacement by the Rio Santa Catarina and Rio La Silla. All 45 photographic records of P. septentrionalis have been observed in wild habitats, 18 photo records in rural environments, and six photo records in urban areas of Nuevo León. Although it has been reported in urban areas, this species has not been reported of importance as a pest. On the other hand, two color patterns have been observed, one light (male) and one darker (male), both are sympatric.
