Genus

Literally: two-colored belt / girdle
| Part | Meaning | Language | Note |
|---|---|---|---|
| di- | double, two | Greek (di, -s) | Standard Greek numeral prefix; the form di- (not dis-) is used before a consonant |
| -chro- | color | Greek (chrom, =a, -ato, -o) | Combining stem of chroma (color); the -m is elided before the connecting vowel; cf. dichroic, dichromatic |
| -zona | a belt, zone, girdle | Greek (zon, =a, -i) | Used here in the standalone Latin-form =a (feminine nominative singular), making the genus feminine |
Dichrozona is a compound Greek noun formed from the numeral prefix di- (two) + the color-stem chro- (from chroma) + the head noun zona (belt, girdle). The -o- at the end of chro- is the connecting vowel linking the modifier to the head. The whole word functions as a feminine Latin-form noun in the nominative singular, as befits a genus name. Literally it describes an organism bearing a two-colored band or girdle—consistent with the distinctive banded patterning seen in the butterfly genus Dichrozona (Riodinidae).
Pronunciation
- di-KROH-zo-nuh Four syllables (di-chro-zo-na). Penult 'zo' has a short vowel followed by only one consonant (n) — no penult-stress trigger fires. Stress therefore falls on the antepenult 'chro'. Its vowel 'o' is long because it is followed by a single consonant (z) then another vowel (o), satisfying the antepenult long-vowel condition.
Other readings
dich-ro-zona: dich- (Greek: two, in two) + -ro- (unclear) + -zona (belt) — less satisfying because 'ro' has no independent meaning; the di- + chro- + zona reading is strongly preferred.
The root chro- (color) is the elided stem of chroma (chrom-); the dictionary entry is 'chrom, =a, -ato, -o' (Greek: Color). The -m drops before the connecting -o- in the same way it does in English 'dichroic' and 'dichromatic'. The genus Dichrozona (Staudinger, 1887) is a small riodinid butterfly genus from South America; the name alludes to the two-colored (typically orange-and-dark) transverse band across the hindwing. Per MODE 2 rules, ch = hard 'k', so 'chro' is pronounced 'kro', not 'shro' or 'chro'.
