Species Guides

Agroecotettix modestus(Modest Aridland Scrub Jumper)

Agroecotettix is a of medium-sized brachypterous grasshoppers in the Melanoplinae, containing 19 described . These short-winged, -limited grasshoppers inhabit aridland scrub and desert regions of the southwestern United States and Mexico. The genus was revised in 2024 with the description of 16 new species, revealing previously unrecognized diversity in this cryptic group. Species identification relies primarily on male genitalia .

Identification

Distinguished from similar Melanoplinae by combination of brachypterous condition, large , broadly oval tegmina, and male . -level identification requires examination of male genitalia: valve shape and epiphallus structure separate the aristus group from the crypsidomus group. Females lack reliable external diagnostic characters and are difficult to identify to species.

Habitat

Open xeric desert scrub, shrublands, and plains; specifically associated with mountainous regions of Texas and Mexico, South Texas Plains ecoregion, Edwards Plateau, Chihuahuan Desert, and Sierra Madre Oriental. Often found on thorny leguminous shrubs including Acacia and Vachella; also observed on Sotol (Dasylirion) and other desert vegetation.

Distribution

Central Texas to southeastern New Mexico, south to central Mexico; concentrated in biologically diverse arid regions including Edwards Plateau, South Texas Plains, Chihuahuan Desert, and Sierra Madre Oriental. Mexican occurs in some .

Behavior

Brachypterous with limited capability; individuals shelter from midday heat on undersides of leaves, particularly Sotol. One (A. chisosensis) has been observed feeding on Dasylirion flowers. Roosting in groups of 40–50 individuals has been documented during extreme heat (113°F conditions).

Human Relevance

Subject of recent taxonomic revision that named after notable cultural figures including LeVar Burton, Ted Turner, Michael Dorn, Jay Silverheels, Clayton Moore, and Frida Kahlo. Research highlights importance of historical museum collections for understanding biodiversity.

Taxonomic History

Originally described by Bruner in 1908 with single A. modestus. Major revision by Hill (2024) in ZooKeys described 16 new species, expanding from 3 to 19 species. Research relied heavily on historical collections from Academy of Natural Sciences, University of Michigan Museum of Zoology, Brigham Young University, and Mississippi Entomological Museum, particularly specimens collected by Dr. Theodore Cohn in Mexico during the 1950s–1960s.

Conservation of Type Localities

Several historical collection sites in Mexico are now considered too dangerous to access, underscoring the irreplaceable value of museum specimens for contemporary biodiversity research.
