“ Chimerothalassius ” sp. 2

( Fig. 3 )

Material. NEW ZEALAND: Three Kings Is., [Great Island,] Castaway camp, Nov. 1970, G. Kuschal, intertidal zone (1♀, NZAC) .

Remarks. While sorting a loan of NZAC Empidoidea in the early 1990s, Brad Sinclair (pers. comm., 2022) noted examining a single female parathalassiine specimen, with wing cell dm absent, from the Three Kings Islands (Manawatâwhi). The specimen, provisionally determined as Microphorella , was returned in 1995, but could not be located in the Diptera holdings of the NZAC (D. Ward, pers. comm., 2022). Although examination of the specimen will be required for precise identification, we strongly suspect it belongs to Chimerothalassius , in which case it would represent the most northerly record of the genus in New Zealand ( Fig. 3 ).
