Type material. MYANMAR, Kachin State: Holotype male from Kambaiti Pass [25.40°N, 98.15°E], 2073 m, 23 April 1934, Malaise leg. ( NHRS, NRM0003 ) GoogleMaps . Paratypes: 2 females, with same data as for holotype, except for: 15 April 1934, Malaise leg. ( NHRS, NRM0001 – NRM0002 ) GoogleMaps .
Etymology. The specific name is derived from the Latin adjective acer, -ris, - re meaning “sharp”, referring to the tip of dRTA; adjective.
Diagnosis. The male of P. acris Zhang, Jäger & Liu , spec. nov. is similar to that of P. coenobium Jäger et al., 2015 , P. digitata Jäger & Vedel, 2007 and P. daxing Zhao & Li, 2018 ( Jäger & Vedel 2007; Jäger et al. 2015; Jiang et al. 2018): 1) E extremely broadened, covering more than half of T; 2) E flattened, with EP on its prolateral margin. It can be recognized by the middle part of RTA almost parallel to Ti in longitudinal axis (slightly bent in P. coenobium , P. digitata and P. daxing ). The female of P. acris Zhang, Jäger & Liu , spec. nov. resembles that of P. contentio , P. digitata and P. saetosa Jäger & Vedel, 2007 ( Jäger & Vedel 2007) in having similarly shaped LL, round S visible in ventral view and more or less straight anterior margins of LL, but may be distinguished by: 1) Distance between S and the latero-posterior margin of LL larger than S diameter here (smaller in P. contentio , P. digitata and P. saetosa ); 2) Anterior margin of the EF is trilobate (only bilobate or without distinct bulges in P. contentio and P. saetosa ).
