Specimen curated in the TAMUIC
Range:
Most records from the Brownsville/Palm Grove area of Cameron Co., Texas except the following:
Texas, Cameron Co., Los Fresnos, VI-13-1969, Board & Hafernik
Texas, Hidalgo Co., Mission, July 12, 2008, J. Dauphin & M. B Stowe
Texas, San Patricio Co., Lake Corpus Christi State Park, VI-17-1969, Robert L. Heitzman
Mexico, Tamaulipas, 7 km SSE Gomez Farias, Bocatoma, V-27-28-1978, E. G. Riley
Type Locality:
Charles Schaeffer collected the type specimen in "Brownsville," Cameron Co., Texas on January 17, 1923. (Schaeffer 1931) This specimen is at the Smithsonian.
Larval Hosts:
Clark et al. (2004) report, "We have collected adults of this species, and larvae presumably belonging to this species, from Passiflora filipes Benth. (Passifloraceae) in southern Texas."
Richardson (1995) reports P. filipes from "Cameron [county] (the only Texas locality) and south. Palm groves, thickets. All seasons." Native Plant Project reports its native range as limited to resaca woodlands in southern Cameron County. Likewise, the USDA PLANTS Database shows the U.S. range of Passiflora filipes Benth. - Slender Passionflower as limited to Cameron County.
Similar Species:
Disonycha is comprised of 145 described species and is restricted to the New World. (Arnett et al. 2002)
There are 36 species of Disonycha recognized north of Mexico. (Arnett et al. 2002)
Twenty-one species occur in Texas (Riley et al. 2003)
Etymology: Disonycha stenosticha Schaeffer
dis (G). Separate, apart; double, two
nyc, -t, -ti, -to (G). Night
sten, -o (G). Narrow

"His favorite collecting site in the Lower Rio Grande Valley was the Esperanza Ranch located a few miles east of Brownsville, TX. Many species of Coleoptera, as well as members of other orders, have the Esperanza Ranch site as their type locality. Unfortunately, this entomologically important site of original dense shrubs and woods along the Resaca de la Palma has succumbed to urbanization and exists no more as a viable biological entity."
