Diagnosis
Ornebius aperta can be reliably differentiated from other species of Ornebius , and from the population further north in Northland, only by its song, a sequence of chirps made of three pulses at a peak frequency between 4.5 and 5.6 kHz. The interval between the first two pulses is much longer than the interval between the second and third pulses.
Male paraprocts pale brown, club-like in shape, narrowest at the base and widest one fifth of the length from the apex.
Etymology
After aperta , ‘hill’, because of its origin from Tamborine Mountain in Australia. From one of “several small dictionaries covering a number of languages spread across Australia ” (D. Otte pers. com. 2023). Aperta is used as a name in apposition.

Description
For a detailed description of Ornebius aperta see Otte & Alexander (1983: 396–397) and Ramsay (1991). Images of the main characters are in Fig. 33 View Fig . The male genitalia and the song are described in detail below, since they are the only traits that differentiate Ornebius aperta from other species in the genus, including Ornebius aff. aperta in Northland.
MEASUREMENTS. See Table 8 View Table 8 . Females are larger than males.
MALE TERMINALIA ( Figs 33D–E, G–I View Fig , 36A–D View Fig ). Suranal plate without hair spikes projecting backwards from posterior margin ( Fig. 33D–E View Fig ). Paraprocts pale brown, club-like in shape, narrowest at base and widest one fifth of length from apex ( Figs 33G–I View Fig , 36D View Fig ).
SONG. A melodious sequence of chirps with a peak frequency between 4.5 kHz and 5.6 kHz, separated by intervals of approx. 1 second; each chirp consisting of 3 pulses, the first two pulses 280 ms apart, the second and third pulses 40 ms apart. Pulse duration is approx. 30 ms. See also Fig. 34 View Fig and Table 8 View Table 8 .
Habitat and ecology
An arboreal scaly cricket, nocturnal, locally abundant. Its melodious song is heard from dusk into the night in urban parks and in the streets of Auckland; the cricket is common in hedges in residential areas.
Distribution
Auckland and surrounds; also Coromandel, Waikato and New Plymouth, Taranaki. Introduced to New Zealand by anthropogenic means. Origin in Tamborine Mountain, Queensland, Australia; accidentally introduced to Perth, Western Australia.
