Neoperla securifera Zwick

Neoperla securifera Zwick, 1986a:28 . Holotype ♂ (Rijksmuseum van Natuurlijke Histoire, Leiden), Midden‐ Oost Expedition, between Samarinda and Long Petak, Borneo

Material examined. Brunei Darussalam: Temburong District, Sungai Belalong, Kuala Belalong Field Studies Centre, 04.54822 ° N, 115.15823 ° E, ALS B11‐08, 11 June 2008 , A.L. Sheldon, 1 ♂ (BPS) .

Remarks. Zwick (1986a) found this to be a variable species based on a few males collected at several Bornean sites. The aedeagus of the male listed above is very similar to Fig. 56 in Zwick (1986a) but the median process of tergum 7 more closely resembles that of N. multilobata Zwick. This is the first record from Brunei Darussalam.
