Espeland, Marianne, Sjoeberg, Tin & Johanson, Kjell Arne, 2020, Description of 47 new species of the New Caledonian endemic caddisfly genus Agmina Ward & Schefter (Trichoptera, Ecnomidae), ZooKeys 956, pp. 49-162 : 49

Agmina campanula sp. nov. Figs 64-68

Diagnosis.

This species is very similar to A. semicampanula sp. nov., from which it is distinguished by the rectangular-shaped anterior margin of segment IX in ventral view; the angled sternal process in lateral view; and, in dorsal view, the pair of parameres that have sharply angled instead of rounded posteromesal corners.

Etymology.

Campanula, named for the bell-shaped flowers in the genus Campanula , based on the shape of the inferior appendages in ventral view.

Measurements.

Fore wing length 3.1-4.0 mm (N = 4). Total length of genitalia: 0.4 mm.

Description.

Genitalia: In lateral view, segment IX sharply triangular anteriorly, apex located medially; in ventral view anteriorly obround. Sternal processes, lateral view, with each apex almost reaching apex of superior appendage, narrowing along its length, curving downwards, apex acute; in ventral view, robust, diverging, first 2/3 of equal width, apices parallel, narrowing, acuminate. Tergum X in lateral view irregularly quadrilateral with concave anterior margin, tapering towards posterior, approx. same length as superior appendage; in dorsal view, mesally fused, forming rounded lobe, inner margins forming narrow bell. Parameres starting before tergum X, in lateral view long, slender, straight, acute apex slightly directed dorsad; in dorsal view, long, slender, widening at truncated apex, posterior margin straight. Superior appendages, in lateral view, oblong, with posterodorsal indentation, approx. same length as tergum X; in dorsal view stout, almost semi-circular with rounded outer margin, inner margin semi-straight, at apex large claw-shaped structure directed anteromesad. Inferior appendages, in lateral view, with posterad orientated rectangular dorsal branch and directly adjacent slender ventral branch of equal length, whole structure semi-rectangular; in ventral view bell-flower shaped. Phallus, in lateral view slightly shorter than segment IX, posterior half tapering along its length; in ventral view tubular with small lateral lobes at anterior end.

Additional information.

This species was referred to as "sp. 24" in Espeland and Johanson (2010a).
