Re: insects names
Here's my best attempt using Liddell & Scott. Greek words are in Greek characters (Latin transliteration in brackets); Latin words are in Roman characters. Those words with an asterisk are proposed neo-Latin compound adjectives, not actual attested words.
Dictyla Nassata
δίκτυον [dictyon] = net
nassa = a narrow-necked basket for catching fish hence: trap, net, snare
(perhaps: nassatus,-a,-um* "relating to a net" or "net-like".)
Codophila Maculicollis
κωδύα [codya] = head of a plant hence: bulb, bean, inflorescence, etc.
φίλος,-η,-ον [philus,-a,-um] = dear, beloved; friendly, loving
(perhaps: codophilus,-a,-um* "inflorescence-loving")
macula = spot, mark
collum = neck
collis = hill, hillock
(perhaps: maculicollis,-e* "spotted-necked")
Chroantha Ornatula
χρώς [chros] = skin; complexion
χρῶσις = [chrosis] coloring, tinting
ἄνθη [anthe/antha] = blossom, flower
(perhaps: chroanthus,-a,-um* "flower-skinned" or "flower-colored")
ornatus,-a,-um = adorned, decorated
ornatulus,-a,-um (diminutive) = rather elegant
Rhyparochromus Saturnius
ῥυπαρός,-ή,-όν [rhyparus,-a,-um] = filthy, dirty
χρῶμα [chroma] = complexion, color
(perhaps: rhyparochromus,-a,-um* "filthy-colored")
saturnius,-a,-um = of Saturn, saturnian
Lethaeus Fulvovarius
λήθαιος,-α,-ον [lethaeus,-a,-um] = causing forgetfulness; oblivious hence: (in Latin) relating to Lethe, of the underworld
fulvus,-a,-um = tawny, yellowish brown
varius,-a,-um = diversified, variegated
(perhaps: fulvovarius,-a,-um* "multi-hued brownish")
Ischnopeza Pallipes
ἰσχνός,-ή,-όν [ischnus,-a,-um] = dry, withered; thin, lean, light; weak, feeble
πεζός,-ή,-όν [pezus,-a,-um] = on foot, walking
(perhaps: ischnopezus,-a,-um* "light-footed")
pallidus,-a,-um = pale, wan, sallow
pes = foot
(perhaps: pallipes* "pale-footed")
Edit: I'm a bit confused as to why some of the names are feminine in form and others are masculine, but I must admit I know absolutely nothing about biological nomenclature. Do you happen to have any idea why they're like that, scrabblehack?
I did notice that with the binomial system the first name is always derived from Greek and the second name from Latin. Interesting.
