Masasatoi View in CoL group

Quedius masasatoi Smetana, 2007 , from China (Fujian, Yunnan), Laos and Vietnam, was previously included in the Apicicornis group of Smetana (2017a), likely out of convenience as it is rather different in habitus. In a similar way, Smetana (2007) placed Q. masatakai Smetana, 2007 , from Laos and Vietnam ( Smetana & Brunke 2021), in the Ripicola group even though it was rather different in habitus. Recently, these two species were shown to be sister groups within ‘Clade E’ of the Microsaurus lineage, and together were sister to a species here described as Malaisdius smetanai gen. et sp. nov. ( Brunke et al. 2021). Quedius masasatoi and Q. masatakai are here included in a newly delineated group, which also includes Q. piceolineatus Scheerpeltz, 1965 from the Malaise material collected in northern Myanmar. A new genus will need to be described for this group but additional morphological study is required in order to provide a more robust diagnosis. The Masasataoi group is provisionally diagnosed within the Microsaurus lineage by the following combination of characters: head with eyes large, clearly longer than temples but temples well-developed ( Fig. 2D View Fig ), eyes protruding from lateral head margin, posterior frontal puncture situated at about hind margin of eye, without additional punctures between posterior frontal puncture and basal punctures; antennomeres 6–10 flattened as typical for Quediini , not inflated; pronotum slightly explanate, marginal punctures not removed from marginal bead, anterior angles with marginal bead partly hidden in dorsal view, dorsal row with second and third punctures rather close together (about one puncture diameter or less) and separated from the first by a long gap ( Fig. 5F View Fig ), at least on one side; sublateral row not extended posteriad of large lateral puncture, without additional punctures between dorsal and sublateral rows ( Fig. 5F View Fig ); scutellum impunctate but sometimes with micropunctures or scratch-like elements, elytra sparsely but evenly punctate, punctures setose ( Fig. 5F View Fig ); abdominal tergites III or III–IV with median impunctate area ( Fig. 2D View Fig ); mesotarsomeres 2–4 short, triangular.
