Escaryus sibiricus Cook 1899: 304.

Escaryus sibiricus - Attems 1904: 122; 1927: 301; 1929: 95; Titova 1972: 135; 1973: 94, 113; Ganin 1997: 141; Thofern et al. 2021: 30.

Type locality.

Russia: Maritime krai: “Vladivostock” ( Cook 1899) = Vladivostok city, 43°7'N, 131°54'E.

Type series.

Syntypes: 12 specimens, both sexes, including 10 specimens deposited in ZMH ( Thofern et al. 2021) and 2 specimens deposited in NHMW ( Ilie et al. 2009).

Diagnosis.

An Escaryus species with body length reaching 6.5 cm; labral arc relatively shallow, with middle denticles obtuse and lateral ones long and pointed; first maxillae with two pairs of lappets; forcipular trochanteroprefemur with a small distal bulge, other forcipular articles without denticles; 49-51 leg-bearing segments; metasternite of the ultimate leg-bearing segment rectangular, ~ 2 × as long as wide; coxal pores of different size, on both ventral and lateral sides, including a pair of much larger ventral pores on each coxopleuron; anal pores absent.

Distribution.

Far East: Maritime krai ( Cook 1899; Attems 1904) and Amur oblast ( Ganin 1997). Outside Asian Russia: no records.

Remarks.

Titova (1969) reported this species from Western Siberia (Kemerovo oblast) but later ( Titova 1973) she regarded the same record as E. koreanus , even though she also suggested that the latter species can be a junior synonym of E. sibiricus . The anal pores were indicated as absent by Cook (1899) and Attems (1904) but illustrated as present in specimens identified as E. sibiricus by Thofern et al. (2021), and they are known to be present in E. koreanus .
