TitleA new variety of an Onomarchus from British India (Orthoptera, Tettigoniidae)
JournalZoologische Mededelingen
AbstractThe following description was made after a single female specimen from the "Museum d' Histoire Naturelle" in Geneva. The specimen differs in some respects from the widely distributed and rather common Onomarchus uninotatus (Serville, 1839, p. 468) which is recorded from the southern part of China, Annam, Malay Peninsula, Sumatra, Java, Borneo, Bangka, Amboina, Batu Islands and Australia, but on the other hand these differences are not of such a striking importance to separate it as a new species. I am inclined to consider the specimen as a local variety of O. uninotatus (Serv.) 1).
Onomarchus uninotatus (Serv.) var. carli nov. var.
Holotype: 1 ♀ from Mudomalai near Madura, South India, leg. Carl and Escher, 8-II-1927.
In general shape and measurements the variety is almost conform the average O. uninotatus but it differs in the following details: The tegmina are of a very light green (Ridgway, 1912, pl. 31, a shade between Glass Green and Kildare Green). Along the veins the colour is slightly darker than in the centres of the cells. There is no distinct white patch at the tegminal basis but a whitish line is found posteriorly along the red Nervus Sector Radii (Rs). A yellow spot is found in the area between the Radial and Medial veins, close to the medial vein about halfway between the base and the origin of the Rs. The lateral lobes of the pronotum are dark brown along the anterior part of the ventral border. The meso- and metasternum are somewhat narrower than in uninotatus, but much broader than in O. eretaceus (Serv.) (=O. submuticus Brunner von Wattenwyl, 1895, p. 44).
The fore-border and fore-angles of the mesosternum are of the same bright
