Note

Nonfried (1894) erected Trichoderma for T. ceylanica based on an undetermined number of specimens from Kandy, Sri Lanka (“Ceylon”). Dalla Torre (1913) proposed Junkia as a replacement name for Trichoderma Nonfried, 1894 (non Stephens, 1848). In the same year Moser (1913) proposed the synonymy of Junkia with Philochlaenia [sic] Blanchard, 1850 and noted that the type locality “Ceylon” was probably a labelling error due to the fact that the genus occurs in South America. Frey (1967) synonymized Junkia with Plectris , and reported its occurrence in Brazil. The original collection of Nonfried is currently housed in ZMHU, but the type series of T. ceylanica was not found. However, two of Moser’s homeotypes of the species from Paraguay were examined ( ZMHU, Fig. 22 E View Fig ). The revalidation of Junkia proposed by the present study is based on these specimens and the original description. Further studies are needed to find or designate primary types, check the taxa systematics, and find the correct occurrence of the species.

The present study revalidates Junkia , formerly a synonym of Plectris , based on the following characters (opposition to Plectris ): labrum transverse, not prominent (prominent and deeply emarginate), metatarsomere I as long as II (metatarsomere I as long as II–IV, Fig. 4 A View Fig ), internal area of metatarsomere V without spine-like setae (with spine-like setae, Fig. 4 A View Fig ).
