Matrona nigripectus m\u00e2le, Tha\u00eflande, Ban Luang, 06\/06\/2024<\/figcaption><\/figure>\n\n\n\n

Matrona nigripectus est un grand Calopterygidae de 62 \u00e0 70 mm (1). Il est facile \u00e0 identifier en Tha\u00eflande ; c’est le seul de son genre et c’est aussi le seul Calopterygidae aux ailes compl\u00e8tement sombres, \u00e0 part Neurobasis chinensis<\/a>, plus petit (56-60 mm) aux ailes plus claires, plus \u00e9troites et \u00e0 la coloration m\u00e9tallis\u00e9e verte du thorax et de l’abdomen, plus jaune.
Il adopte l’habitat classique de sa famille, c’est-\u00e0-dire des ruisseaux et rivi\u00e8res aux berges garnies d’ombre et de soleil, mais il pr\u00e9f\u00e8re la montagne et ne se rencontre pas en plaine. Par exemple le long de la Mae Klang River<\/a>, o\u00f9 nous \u00e9tions \u00e0 environ 400 m d’altitude.<\/p>\n\n\n\n

Selys qui a d\u00e9crit Matrona nigripectus (2) et basilaris (3), et ne connaissait que ces deux esp\u00e8ces, les a trouv\u00e9es tr\u00e8s proches au point qu’il pensait que la premi\u00e8re \u00e9tait \u00ab\u00a0une race<\/em>\u00a0\u00bb de la seconde. Il a not\u00e9 cependant des diff\u00e9rences comme la nervation de la base de l’aile qui appara\u00eet claire jusqu’au nodus, pour peu qu’on ne soit pas dans une vue de profil stricte. Je remarque \u00e9galement que l’aile sombre est enti\u00e8rement entour\u00e9e d’une ligne claire (mais pas toujours…).
Et si Selys fait une r\u00e9flexion sur la couleur de la face ventrale du thorax de M. nigripectus : \u00ab\u00a0La poitrine noire dans les deux sexes fortement tach\u00e9e de jaune livide chez la basilaris<\/em>\u00ab\u00a0, il n’a pas remarqu\u00e9 que la face inf\u00e9rieure des segments 8 \u00e0 10 est noire pour M. nigripectus, jaune pour M. basilaris. Je regrette de ne pas l’avoir su lorsque j’\u00e9tais sur le terrain et je n’ai donc pas cherch\u00e9 \u00e0 le montrer sur mes photos.
Dans Yu, X., Xue, J., H\u00e4m\u00e4l\u00e4inen, M., Liu, Y., & Bu, W. (2015) (4) on trouve une cl\u00e9 pour identifier les Matrona ; elle souligne une autre diff\u00e9rence que je peux constater en comparant mes photos, la densit\u00e9 plus importante de la nervation \u00e0 la base de l’aile pour M. basilaris.

La situation s’est maintenant compliqu\u00e9e puisque neuf esp\u00e8ces sont connues. Matrona basilaris est cependant pr\u00e9sent dans le nord (nord-est plus pr\u00e9cis\u00e9ment) du Laos (4), il n’est donc pas \u00ab\u00a0impossible\u00a0\u00bb de le voir en Tha\u00eflande un jour.<\/p>\n\n\n\n

Une vue \u00e0 peine d\u00e9cal\u00e9e par rapport au profil permet de nettement voir ces nervures basales color\u00e9es ; sans doute ces nervures ne sont-elles claires que sur leurs faces lat\u00e9rales et pas jusqu’\u00e0 leur sommet…
Noter \u00e9galement la taille impressionnante des \u00e9pines des pattes, ce qu’on voit encore mieux sur la derni\u00e8re photo de ce m\u00e2le immature.<\/p>\n\n\n\n

Je regrette de ne pas avoir r\u00e9ussi \u00e0 le photographier les ailes ouvertes, car il est magnifique, la base des quatre ailes \u00e9tant bleu iridescent alors que le reste est sombre… (on a la m\u00eame surprise en observant Neurobasis chinensis).

On rencontre cette esp\u00e8ce du nord-est de l’Inde et du Bangladesh au nord du Vietnam et au Yunnan (Chine) en passant par le Myanmar, le nord de la Tha\u00eflande et du Laos.
IUCN Red List<\/a>.

J’ai finalement aper\u00e7u un tr\u00e8s jeune m\u00e2le aux yeux encore clairs et aux tr\u00e8s spectaculaires \u00e9pines sur les pattes.<\/p>\n\n\n\n

Matrona nigripectus m\u00e2le immature, Tha\u00eflande, Hua Sai Lueang Waterfall, 04\/06\/2024<\/figcaption><\/figure>\n\n\n\n

\u00c9tymologie<\/strong><\/span>
Matrona<\/strong>, du latin matrona<\/em> qui signifie dame<\/em>, femme mari\u00e9e<\/em>. Le terme \u00ab\u00a0matrone\u00a0\u00bb au XIX\u1d49 si\u00e8cle n’avait pas la connotation parfois p\u00e9jorative qu’il a aujourd’hui. Il d\u00e9signait une femme d’une beaut\u00e9 m\u00fbre, imposante et respect\u00e9e<\/b>. Et c’est sans doute cette imposante beaut\u00e9 que Selys a voulu souligner lorsqu’il a cr\u00e9\u00e9 le nom de genre pour Matrona basilaris.
Nigripectus<\/strong> du latin niger, pour noir<\/em> et pectus<\/em>, pour c\u0153ur<\/em> ou poitrine<\/em>. Et Selys \u00e9crit (2) : \u00ab\u00a0La poitrine noire dans les deux sexes <\/em>…\u00a0\u00bb.<\/p>\n\n\n\n
