Lannapsyche Malicky 1989

Oláh & Johanson (2010) summarized the characters of genus Lannapsyche . Based on specimens from Oriental China, additional diagnostic characters for males are as follows: 1) Segment X tall and hood-like, divided apicomesally or completely divided into 2 tall, vertical lobes, each with dorsal margin flattened, setose, and longitudinally strap-like in dorsal view, extended laterad as longitudinal carina, especially subbasally (Figs. 1B, 2B); 2) harpago of each inferior appendage fleshy, with expanded apex covered with short, stout spines (Figs. 1A, 2A). The mesal setal wart (= mesal nodule, Oláh & Johanson 2010) on the first segment of each maxillary palp (Fig. 1E) is also present in both male and female in all 3 Chinese species. The Chinese Lannapsyche species can be collected during daytime along small brooks or spring-fed streams (Oláh & Johanson 2010), but at least some species also come to light traps.
