The Leptophlebiidae : Atalophlebiinae of New Caledonia (Ephemeroptera). Part VII : Systematics

Abstract

The seventh in a series on the Leptophlebiidae O^phemeroptera) of New Caledonia, this papers treats three new genera (Paraluma, Oumas, and Amoa) and 12 new species. For Paraluma gen.n., the type species P. cancellata sp.n., P. triangularis sp.n., P. gilva sp.n. and P. minuta sp.n. are described from male and female imagos and nymphs, P. pulla sp.n. from male imagos and nymphs, and P. maculata sp.n. from male and female imagos. For Amoa gen.n., the type species A. fronini sp.n., A. subsolano sp.n. and A. orthogonia sp.n. are described from male and female imagos and nymphs, A. cressonensis sp.n. from nymphs only and A. hebes sp:n. from the male imago only. Oumas orbis gen.n. sp.n. is described from male and female imagos and nymphs.

Septième d'une série de publications sur les Leptophlebiidae (Ephemeroptera) de Nouvelle-Calédonie, la présente contribution traite de trois genres nouveaux (Paraluma, Oumas etAmoà) et de 12 espèces nouvelles. Pour Paraluma n. gen., l'espèce-type P. cancellata n. sp., P. triangularis n. sp., P. gilva sp. n. and P. minuta n. sp. sont décrites à partir d'imagos mâles et femelles et de larves, P. pulla à partir d'imagos mâles et de larves, et P. maculata n. sp. à partir d'imagos mâles et femelles. Pour Amoa n. gen., l'espèce-type A. frontoni n. sp., A. subsolana n. sp., A. orthogonia n. sp. sont décrites à partir d'imagos mâles et femelles et de larves, A. cressonensis n. sp. à partir de larves seulement et A. hebes à partir d'une imago mâle seule. Oumas orbis n. gen. n. sp. est décrite à partir d'imagos mâles et femelles et de larves.

Big diversity in a small hotspot: two new species of Leptophlebiidae (Insecta, Ephemeroptera) from New Caledonia

“…The only exceptions were two adult specimens of the baetid genus Pseudocloeon (?) found in Rivière Bleue ( Peters et al 1978 ). However, no further specimens of Baetidae have been collected from this area since then, and the occurrence of this family in New Caledonia is therefore doubtful.…”

“…The research on the mayflies in New Caledonia has been led by William L. Peters and Janice G. Peters, who published a series of eight articles focusing on taxonomy and systematics ( Peters et al 1978 ; Peters and Peters 1980 , 1981a , b , 2000 ; Peters et al 1990 , 1994 ; Peters and Mary 2016 ). New Caledonian mayflies belong to a single family Leptophlebiidae and subfamily Atalophlebiinae ( Peters 2001 ).…”

“…In addition to the remarkable number of endemic genera, New Caledonian mayflies are exceptional because they are able to occupy different freshwater microhabitats due to great eco-morphological diversification. Here we describe two new species from morphologically related genera, Fasciamirus and Simulacala , the larvae of which inhabit small stones in quiet sections of streams and burrow in fine gravel in streams and rivers, respectively ( Peters et al 1990 ).…”

Spatio-Temporal Variations in Macroinvertebrate Assemblages of New Caledonian Streams.

“…G2 occur only in peridotitic lands. PETERS et al (1978) and CHAZEAU (1994) suggested a specific endemism of fauna to ultramafic rocks. For example, PETERS et al (1978) examined the distribution of Ephemeroptera Leptophlebiidae Lepeorus over La Grande Terre and showed that the subspecies Lepeorus calidus notialis and L. goyi australis were restricted to the ultramafic South region of La Grande Terre, whereas the subspecies Lepeorus calidus calidus and L. goyi goyi occur everywhere else.…”
