Figure 2. Known distribution of Thorelliola species in tropical southeast Asia and islands of the southwestern Pacific (detail in A). Numbered localities are referenced in Table 1; locality (18) represents our new discovery of this species in Ben Tre Province, Vietnam. Unnumbered localities (white circles) correspond to confirmed records for T. ensifera posted on iNaturalist. With the exception of the widely distributed T. ensifera, each species in this genus appears to be subject to narrow endemicism, with the greatest diversity in tropical Australasia (Sahul) or New Guinea (Papua). The lack of records from most of New Guinea suggests that many more species remain to be found in that place. Four species are known from the transition zone of Wallacea. Thorelliola is presently placed in the Australphryni, a predominantly Australasian clade within the Euophryini with a number of genera that have successfully crossed the islands of Wallacea; this clade also includes the well-know peacock spiders (Maratus), endemic to Australia (Hill 2010, 2022).
