Name
Spartidelphax penedetectus (Beamer, 1950) comb. n. – Wikispecies link – Pensoft Profile
- Delphacodes penedetecta Beamer, 1950: 70.
Type locality
Florida, Levy County, Cedar Keys.
Diagnosis
Slightly larger than Spartidelphax detectus, with vertex longer than wide (l:w 1.34–1.48), aedeagus with a pair of rows of fine ventral serrulations in distal third; base less abruptly narrowed than in Spartidelphax detectus. Parameres in widest view subtly more narrowed on outer angle than Spartidelphax detectus, outer angle slightly curled.
Dimensions. Male brachypter: body length 2.33 mm (2.18–2.57, n=6), vertex l:w (1.48, n=9); male macropter: body Length 3.79 (including wings, 3.62–3.96, n=6), vertex l:w (1.44, n=6). Female brachypter: body length 3.06 (2.87–3.27, n=6), vertex l:w (1.34, n=6); female macropter: body length 4.07 mm (3.62–4.45, n=4), vertex l:w (1.39, n=5). Count of calcar teeth 25 (21–31, n=10).
