Zyras (incertae sedis) fustigans PACE, 2000

Zyras (Zyras) fustigans PACE, 2000: 77 .

Material examined: Thailand: 1 ♂ [teneral], Mae Hong Son, Ban Huai Po , 1600–2000 m, 9.–16.V.1991, leg. Horák ( NMP) .

Comment: The original description is based on a unique teneral male from “ Thailand, Ban Sai Yok, River Kwae” ( PACE 2000). The specimen is deposited in the currently inaccessible collections of the natural history museum in Torino. However, the morphological details and the illustrations provided by PACE (2000), particularly the conspicuous median keel on tergite VII, leave no doubt that the above non-type male is conspecific with the holotype.

Though sharing some first-glance similarities (habitus, coloration), Z. fustigans differs in numerous and significant respects from the subgenus Zyras , e.g., the morphology of the antennae (antennomeres IV–X strongly transverse and strongly flattened), elongate maxillary palpi, strongly flattened and dilated femora and tarsi of the mid- and hindlegs, the punctation pattern of the abdomen (without non-setiferous punctation), the modifications of the male tergites V (with pronounced antero-median tubercle) and VII (with pronounced median keel, a conspicuously broad male sternite IX, the morphology of the median lobe of the aedeagus (with pronounced long dorso-apical structures), and strongly modified parameres. In fact, the morphology of the aedeagus somewhat resembles that of the subgenus Termidonia MOTSCHULSKY, 1860 .
