Delphacodes trimaculata
Beamer, 1948
Delphacodes trimaculata is a of delphacid planthopper in the Delphacidae, first described by Beamer in 1948. It is a small, sap-feeding insect belonging to the order Hemiptera, suborder Auchenorrhyncha. The species is found in North America, with distribution records from Arkansas, Connecticut, District of Columbia, Florida, and Illinois. As a member of the Delphacodes, it shares characteristics typical of this group of planthoppers, including a movable spur on the hind tibia.

Identification
The specific epithet "trimaculata" (meaning "three-spotted") likely refers to distinctive maculations or markings on the body, though detailed morphological descriptions are not readily available in the provided sources. Members of Delphacodes can be distinguished from other delphacid by features of the male genitalia and the structure of the . -level identification within Delphacodes typically requires examination of male genitalia and sometimes female ovipositor structure. Without access to the original description or diagnostic keys, specific distinguishing features from cannot be reliably stated.
Distribution
North America: United States (Arkansas, Connecticut, District of Columbia, Florida, Illinois). The has been documented in the eastern and central United States based on collection records.

Taxonomic Status
The Catalogue of Life lists this as a synonym under "Delphacodes trimaculatus", while GBIF and iNaturalist treat "Delphacodes trimaculata" as the accepted name. This discrepancy reflects historical variation in gender agreement for species epithets in the Delphacodes. The original combination by Beamer (1948) used "trimaculata" to agree with the feminine genus name Delphacodes.
Data Availability
Information on this is extremely limited in publicly accessible sources. The original description by R.H. Beamer in 1948 and any subsequent taxonomic revisions would be necessary to provide accurate morphological descriptions, plant associations, and ecological details. The low number of iNaturalist observations (3) suggests it is either genuinely rare, undercollected, or difficult to identify in the field.
