The OFFICIAL DATE OF PUBLICATION is handstamped in a limited number of initial copies and is recorded in the institution's annual report, Annals of the Smithsonian Institution. A world classification of the Harmacloninae, a new subfamily of Tineidae (Lepidoptera: Tineidea) / Donald R. Smithsonian contributions to zoology ; no. 597). Diakonoff (1968) retained Harmaclon in the Tineidae, as did Nielsen and Common (in CSIRO, 1991) and Robinson and Nielsen (1993) in their treatment of the Australian fauna.

USNM collections of the former United States National Museum, now deposited in the National Museum of Natural History, Smithsonian Institution, Washington, D.C. In the most recently published overview of the subject to date, Robinson (in Robinson and Nielsen, 1993) acknowledged 11 subfamilies within the questionably monophyletic family Tineidae.

Unique Forewing/Hindwing Secondary Coupling Sys- tem: Bradley (1953a) first described this very effective wing

Adults are nocturnal and phototropic, and the majority of species apparently fly year-round in tropical areas. Nine were assumed to be monophyletic, and the remaining two, Meessiinae and Myrmecozelinae, were not defined by any known synapomorphies. Myrmecozelinae in particular were thought to be polyphyletic; however, they may contain a larger monophyletic unit characterized by Myrmecozela (type species: ochraceella TengstrSm) on the basis of certain shared male genitalia.

Harmaclona was recently grouped with Myrmecozelinae (Robinson and Nielsen, 1993), more or less by default, because several characters excluded it from other, more well-defined subfamilies. Partly because I agree with Robinson about the polyphyly of Myrmecozelinae, I believe it is prudent and more informative to recognize Harmaclona together with its revived sister genus Micrerethista as a separate subfamily, defined by the following synapomorphies .

Loss of Pretarsal Arolium and Pseudempodial Seta: The associated loss of both the arolium and pseudempo-

Robinson (in Robinson and Nielsen, 1993) observed females ovipositing between cork and glass in a collection vial, with the eggs covered by the female's nuchal hairs.

Abdominal Tympanic Organs: Auditory organs have evolved in only about 15 of the 119 families of Lepidoptera

The tympanic organs of the Harmacloninae are situated at the base of the abdomen on the anterior half of the second sternum, in a position similar to those of the Pyraloidea. The tympana are elliptical in outline and extend approximately half the length of the second sternite in both sexes. A shallow, external cavity is formed immediately anteroventral to the tympanum by the concavity of the adjacent metacoxae.

Dissection of the abdomen revealed a single air chamber, lined with membrane, beneath the tympanic membrane. A broad, thin band of tissue, perhaps containing the scoloparium, was attached to the inner wall of the tympanic membrane in the region of the spinula (Figure 107).

Enlargement of Sternal Apophyses: The slender apo- physes projecting anteriorly from abdominal sternum II

Harmaclona cossidella: 9, male; 10, female; 11, enlargement of figure 9, showing spherical sensory cavities in flagellomeres 1–5 (see arrow); 12, enlargement of figure 10, showing sensory cavities in flagellomeres 1–9 (see arrow). As a result, attempts to remove the abdomen for genital dissection often result in a separation between the meso- and metathorax. A cursory examination of dried and cleaned specimens revealed no evidence of hard-walled internal cavities or remnants of scolopia attached to the tympanic spinula.

Aedoeagus with Basal Midventral Keel: The ridge-like keel developed at the base of the aedoeagus (Figures 166,184)

Analysis of the data for 22 taxa (excluding Micrerethista fused) by the implicit summary option (ie*) of Hennig86 initially resulted in 496 trees (length = 106; Harmaclona hilethera is believed to be more derived (Figure 91) than suggested by his more apomorphic anellus—the most specialized form within the genus. The apex of the valva is entire in Gerontha (Moriuti, 1989) and is rarely divided or deeply notched in Myrmecozelinae (Zagulajev, 1975).

The presence of the basal midventral keel on the aedoeagus constitutes an autapomorphy for the Harmacloninae. This characteristic cluster of spines constitutes a synapomorphy of the Micrere-Thista entripta species group (Figs.
