Ecnomina zealandica is a species of caddisfly belonging to the family Ecnomidae.[2] The species was first described by Keith Arthur John Wise in 1958,[2] and is endemic to New Zealand.[3]
Taxonomy
[edit]The species was identified by Wise in 1958, and is the only known member of the genus Ecnomina in New Zealand.[3] Because of this, observations of Ecnomina larvae in New Zealand are assumed to be Ecnomina zealandica.[4]
Description
[edit]Wise's original text (the type description) reads as follows:
HEAD fuscous; ANTENNAE ochraceous. THORAX fuscous, LEGS ochraceous. ANTERIOR WING light fuscous, fringe darker. VENATION. In anterior wing apical forks 3 and 4 sessile, the median cell extending between them. In posterior wing apical fork 3 about as long as its footstalk. Length of anterior wing, 3.5 mm (0.14 in).[3]
Wise noted that the species could be distinguished from Australian Ecnomina species by the apical forks 3 and 4 of the anterior wing being sessile and not stalked.[3] The larvae are 4.8 mm (0.19 in) in length.[4]
Distribution and habitat
[edit]The species is endemic to New Zealand.[3] While specimens have primarily been collected from the Auckland Region and Waikato Region, the species' range is likely wider.[4][5] It has been described as one of the rarest caddisflies in New Zealand,[6] with no observations of the adults of the species between the 1940s and 2002, when specimens began to be identified in Malaise traps.[7] Drinan et al. (2020) speculate that the species' rarity may point to a behavioural difference in the species, such as being diurnal, or not being attracted to ultraviolet light.[7]
Larvae of E. zealandica have been collected from Fissidens moss from stream banks.[4]
