Edmunds, 24 &amp;female; (BPS). <b>Remarks.</b> Although there are two apparent Bornean <i>Tetropina</i> species, the small number of specimens available and the fact that the type specimens of <i>T. fulgescens</i> and <i>T. larvata</i> are opposite sexes led Zwick (1984) to suggest the possibility that the two names might represent only one species. We are able to formally establish this synonymy on the basis of the long series of males listed above which share hemiterga of the “ <i>T. larvata</i> ” type (<i>sensu</i> Zwick 1984) and are associated with females (and mature egg bearing nymphs) of the <i>T. fulgescens</i> type. Zwick’s (1984) figure of an egg taken from the holotype shows the chorionic surface to be coarsely punctate with shallow, widely spaced pits, and a distinct operculum is present. This figure is in agreement with scanning electron micrographs prepared from eggs taken from the females listed above (Figs. 26&amp;hyphen;27) and from mature nymphs (Figs. 28&amp;hyphen;29) from the same sites. Eggs taken from females of a Sabah population are also shown to indicate variation in chorionic morphology for this species (Figs. 30&amp;hyphen;31). Zwick (1984) suggested the anchor might be mushroom shaped but these figures clearly show the medusoid character of the structure which Zwick (2000) discovered. A consequence of this synonymy is the female specimen of “ <i>T. larvata</i> ” from “Midden, O. Borneo, 24.VIII.1925 (Siebers; ML)” in Zwick 1984, and the three male specimens of <i>T. fulgescens</i> (Zwick 1984) are left without a name. We are not proposing a new name (or names) at this time, however, since we have not studied these specimens.
