Acantholimnophila bispina (Alexander, 1922)

( Figs 28–31 )

Acantholimnophila bispina (Alexander, 1922) . Type species: Limnophila bispina Alexander, 1922b: 310 (original description); Alexander, 1924: 368 (taxonomy); Ribeiro, 2008: figs. 96, 170 (illustrations of male genitalia); Oosterbroek, 2011 (catalogue citation).

Diagnosis. Acantholimnophila bispina distinguishes from A. maorica mainly by having the interbase relatively shorter and stouter, terminating in a bifid tip.

Dimensions. Thorax length, 1.00– 1.12 mm; thorax height, 0.82–0.87 mm; wing length, 5.95–7.0 mm; wing width, 1.33–1.68 mm; gonocoxite length, 0.40–0.54 mm; gonocoxite width, 0.18–0.21 mm; clasper of gonostylus length, 0.18–0.19 mm; clasper of gonostylus width, 0.03 mm; lobe of gonostylus length, 0.18–0.21 mm; lobe of gonostylus width, 0.03 mm.

Material examined. Holotype. Male. Graymouth, New Zealand [South Island, 49°27’S 171°12’E], Sea-level, sept. 7, 1921, T.R. Harris.

Preservation. The specimen is nearly intact, with one wing and terminalia mounted in a separate microscope slide.

Non-types. 1 male. New Zealand, Ross [South Island, 42°53’170°48’], Westland, Feb. 21, 1923, T.R. Harris | Acantholimnophila bispina (Alex.) , Det. C.P. Alexander, 1923. 1 male. New Zealand, White Rock, Mt. Thomas, Canterbury, [South Island, 43°09’S 172°21’E] Alt. 800 ft [243.8m], xi–26 –’22 [November 26, 1922], J.W.Campbell | Acantholimnophila bispina (Alex.) . 1 male. New Zealand, Glentui [South Island, 43°13’S 172°17’E], S. Lyndsay | Acantholimnophila bispina (Alex.) , Det. C.P. Alexander, 1921.

Remarks. The diagnostic features of both Acantholimnophila species refer to details of the male genitalia. Malefemale associations are difficult to be defined objectively, and can only be presumed on the basis of co-occurrence.
