Neuroctenus hopkinsi

Distinguished from other Neuroctenus species by subtle morphological features of the pronotum and wing venation patterns, requiring examination of male genitalia for definitive identification. The flattened body form separates it from most other Hemiptera families, while genus-level identification requires comparison with congeneric species such as N. simplex and N. pseudonymus.

Body strongly dorsoventrally flattened, an adaptation for inhabiting tight spaces under bark. Antennae with four segments. Wing pads present in macropterous forms or reduced in brachypterous forms. Coloration generally dark brown to black, providing camouflage against bark and decaying wood substrates.

Found under bark of dead or decaying trees and in rotting wood, where humidity remains high and fungal growth is abundant. Specific host tree associations have not been documented.

Recorded from North America; precise range boundaries within this region are undefined due to limited collection records and taxonomic study.

• Neuroctenus simplexOverlapping North American distribution and similar flattened body form; distinguished by male genitalia and subtle pronotal differences.
• Neuroctenus pseudonymusCongeneric species with similar habitat preferences; separation requires detailed morphological examination.
