Additions and amendments to the New Zealand Trichoptera

Features of the family Oeconesidae (Tillyard, 1921) are considered with special reference to the recent work of Neboiss (Australian Entomological Magazine 2(4): 79–85). Under Philopotamidae Stephens, 1829, Dolophilodes (Hydrobiosella) mixta n.sp. is described from material hitherto included in: D. (H.) stenocerca (Tillyard, 1924). Pycnocentrodes Tillyard, 1924 (in Sericostomatidae Stephens, 1836) is revised as follows: P. chiltoni Tillyard, 1924 and P. unicolor Wise, 1958 are synonymised with P. aureola (McLachlan, 1868); P. modesta n.sp. is described from material from the northern half of the North Island; and P. aeris Wise, 1958 is confirmed as a distinct species.
