Belocephalus subapterus

Distinguished from Pyrgocorypha uncinata (Hook-faced Conehead) by geographic distribution: B. subapterus is strictly limited to the southeastern coastal plain (Alabama, Florida, Georgia, North Carolina, South Carolina), whereas P. uncinata occurs more broadly including Arkansas and inland areas. The cone shape is similar but species-level identification requires geographic confirmation. Reduced wings (subapterous condition) may aid separation from fully winged congeners.

Possesses the enlarged, forward-projecting cone (fastigium) diagnostic of Copiphorini, with a shape resembling that of Pyrgocorypha uncinata. The cone extends prominently from the frons and vertex. Compound eyes are positioned close to the antennal bases, creating a 'pupil effect' that gives the appearance of forward-facing gaze. Body coloration includes brown and green forms. Wings are reduced or abbreviated, as suggested by the specific epithet 'subapterus' (meaning 'almost wingless' or 'with small wings').

Southeastern coastal plain environments; specific microhabitat preferences not documented in available sources.

Endemic to the southeastern United States coastal plain. Documented from Alabama, Florida, Georgia, North Carolina, and South Carolina.

• Pyrgocorypha uncinataShares nearly identical cone shape and 'hook-faced' appearance, leading to past misidentification. Separated by geographic range: P. uncinata occurs in Arkansas and broader distribution, while B. subapterus is strictly coastal plain.
• Neoconocephalus spp.Common conehead katydids in same subfamily but lack the distinctive hooked tip on the cone found in Belocephalus.
