Percnostola
perk-NOS-toh-luh
Genus
The dark-cloaked one; dark-mantled bird
Literally: Dusky robe
| Part | Meaning | Language | Note |
|---|---|---|---|
| percno- | dusky | Greek (percn, -o) | combining form; the final -o is the Greek connecting vowel |
| stola | a long robe | Latin (stol, =a, -o) | standalone form stola; nominative singular feminine; originally borrowed into Latin from Greek stolē (στολή) |
The name is a single-word genus noun treated as feminine in Latin (stola is a 1st-declension Latin feminine noun). The first element percno- is a Greek combining form meaning 'dusky', functioning as an attributive modifier to the head noun stola ('robe'). Together they produce the compound 'dusky robe', alluding to the dark, mantle-like plumage that covers these antbirds. The formation is a Greco-Latin hybrid — a common practice in 19th-century ornithological nomenclature — where a Greek colour-root is prefixed to a Latin noun in apposition-style compounding.
Pronunciation
- perk-NOS-toh-luh Four syllables: perc-nos-to-la. The penult 'to' has a short vowel (o) followed by a single consonant (l) with no following diphthong or long-vowel marker → penult is light, so stress retreats to the antepenult 'nos'.
Other readings
A purely Greek reading is possible if stola is taken as the Greek loanword stolē, making the whole name Greek: 'dark robe / dark mantle'. The dictionary entry lists the term under Latin, so the hybrid reading is preferred.
Percnostola is a genus of antbirds (family Thamnophilidae) erected by Philip Sclater and Osbert Salvin in 1873; the name describes the dark, robe-like plumage of its members. The compound is a Greco-Latin hybrid: percno- (Greek) + stola (Latin). Such hybrids were widespread in Victorian ornithological nomenclature and are nomenclaturally valid under the ICZN even though purists prefer all-Greek or all-Latin formations. The dictionary entry for stola notes that the word entered Latin from Greek stolē (στολή, 'equipment, garment, robe'), so the boundary between Latin and Greek is blurry here; the compound can also be read as entirely Greek in spirit.
