habitat: fresh to highly saline water collected in rock pools and arti- 

 ficial containers near the seacoast. 



Included species. — A. togoi (Theobald). 



Subgroup VII. SCUTELLALBUM 



De-flnition. — Neotropical. Male palpi as in Subgroup III. Basi- 

 style without specialized scale tuft. Hind tarsi with basal and apical 

 white bands on I-IV, V all white. Postspiracular area and parater- 

 gite scaled. Subspiracular area not scaled in male (could not see 

 this character on female) . 



Suppleinentar^ notes. — Claspette filament narrowly bladelike in 

 lateral view. Female tori scaled medially. Scutum with a pattern 

 of thin distinct lines. Preala scaled below knob. Ppn with narrow 

 scales. Larval head hair 5 behind and slightly internal to 6, 7 on a 

 level just anterior to 6, 4 internal to the base of 6. Comb scales in 

 a patch. Larval habitat : rock pools in stream beds. 



Included species. — A. scutellaXbum Boshell-Manrique. 



Subgroup VIII. GRACILELINEATUS 



Defmtion. — Australasian. Male palpi as in Subgroup III. 

 Basistyle without a specialized scale tuft. Hind tarsi with basal 

 bands on I-V, no apical bands (V may have pale reflections dorsally 

 in some lights) . Postspiracular area bare. Subspiracular area and 

 paratergite scaled. 



Supplementary cliaracters. — Claspette filament bladelike. Female 

 tori unsealed. Scutal linear pattern with broken lateral lines, the 

 median line more or less complete, but the lines tending to be indis- 

 tinctly separated anteriorly in male. Preala scaled below knob. Ppn 

 with narrow-cui'ved scales only. Larva unknown. 



Included species. — A. gracilelineatus Bonne-Wepster. 



Group E (MEDIO VITTATUS-group : GYMNOMETOPA) 



Australasian, Oriental, and Neotropical species. Wings not spotted 

 with areas of pale scaling. Scutal marking pattern consisting of a 

 pattern of narrow distinct longitudinal lines of white to yellow scales. 

 Femora (at least the mid-) , and usually also one or more of the tibiae, 

 with an anterior narrow longitudinal line of pale scales for nearly 

 their whole length; not spotted or ringed with pale scaling. Hind 

 tarsi with basal bands on I to IV or V (V may be all white), apical 

 pale scaling also present on some segments (except in mallochi, niedio- 

 vittatus, and fhegneri) . 



In addition the female tori possess a medial scale patch (only hairs 

 or else just a few scales in qulnquelineatu^s) , and the paratergite is 

 scaled. Larval habitat: Tree holes, bamboos, rock pools, and arti- 

 ficial containers.
