Albuna isozona (Meyrick)

Sesia isozona Meyrick, 1886:689

Trochilium isozonum (Meyrick)—Turner, 1917:80

Paranthrene isozona (Meyrick)—Hampson, 1919:104

MALE—Head with vertex smooth, brown-black, yellow-orange anteriorly; occipital fringe pale yellow dorsally, white laterally; antennae brown-black; front yellow; labial palpus relatively smooth, pale yellow with some brown-black near apex Thorax with collar brown-black dorsally, yellow-orange laterally; large yellow patches anteriorly and subdorsally; yellow patches beneath wings; metathorax yellow Abdomen brown-black; dorsally with segments 2, 4, 6, and 7 very broadly banded yellow; ventrally with all segments broadly banded yellow on posterior one-half; anal tuft fan-shaped, brown-black, strongly mixed with yellow scales Legs with coxae and femora brown-black; tibiae brown-black, strongly yellow medially and dorsally; tarsi brown-black with some yellow at joint Forewing mostly hyaline; costal margin, anal margin, well-developed discal spot, and apical margin brown-black; Cu strongly powdered yellow, distal edge of discal spot and veins to apical area powdered yellow Hindwing hyaline; very narrow brown-black margins; fairly strong discal spot brown-black with pale yellow posteriorly Wing length of male, 10–11 mm Male genitalia (Figure 11) much like A coracodes, but with gnathos rounded, not bilobed, with 10–12 spinelike processes on ventral edge; valva with multifurcate scales not extending as far apically, and not as many spinelike scales in saccular region; aedeagus relatively larger and somewhat differently shaped

FEMALE—Quite different from male: head with occipital fringe orange dorsally, pale yellow laterally; antennae brown-black dorsally, orange ventrally; labial palpus relatively smooth, orange Thorax much like male Abdomen dorsally brown-black with segments 2, 4, and 6 broadly banded yellow-orange; ventrally with all segments broadly banded yellow-orange on posterior one-half of segments; anal tuft shorter than male, yellow-orange with brown-black laterally Legs essentially like male Forewing mostly opaque with relatively broad margins and discal spot brown-black; remaining opaque areas orange; hyaline area in cell and just distad of discal spot; fringe brown-black, tipped with orange Hindwing hyaline; narrow margins, veins, and well-developed discal spot brown-black, with some orange at wing base, on discal spot, and on tips of fringe; ventrally with more orange basally and discal spot orange Wing length of female 11 mm The genitalia were completely destroyed by fungi or insects on the only female specimen examined The abdomen was examined carefully but no remnants of the genitalia could be found The entire specimen was in such poor condition that no photograph is provided of the female

TYPE—The following specimens were examined: (1) “Paratype”; “Maryborough, Queensland, GM”; “Paranthrene isozona Meyr, 1/1, E Meyrick det in Meyrick Coll”; “isozona Meyr”; “Meyrick Coll BM 1938–290” (male, in British Museum [Natural History]) (2) “Sesia isozona Meyr, Queensland” (handwritten but not believed to be that of Meyrick); “Queensland”; “Aus Nat Ins Coll”; “On permanent loan from MaCleay Museum, University of Sydney” (male, in Austalian National Insect Collection) (3) “Wide Bay, Queensland”; “Austr Mus Collection” (female, in Australian Museum, Sydney, abdomen removed) Meyrick (1886) in the original description wrote, “Maryborough, Queensland; eight specimens (Australian Museum and Coll Masters)” Most of the syntypes mentioned could not be located Of the three specimens listed above as possible syntypes, the first one, a male in the British Museum (Natural History), has labels indicating to us that it is most likely a valid syntype For this reason the male syntype in the British Museum (Natural History) has been selected, labeled, and is presently designated as the lectotype

TYPE LOCALITY—Maryborough, Queensland

HOST PLANT—Unknown

DISCUSSION—This species, at least superficially, resembles A oberthuri LeCerf (compare to description of latter species) If the two species are closely related, A isozona may be found to be a borer in some species of native vine as was indicated for a specimen of A oberthüri Other than the fact that all specimens examined were taken in January, nothing else is known of the biology of A isozona One male was examined from Bowen, Queensland
