Northern area of Okinawa Island.	en	Jałoszyński, Paweł (2025): A new species and new records of Cephennomicrus Reitter on the island of Okinawa (Coleoptera, Staphylinidae, Scydmaeninae).

03F4D8397C04C35AFF03FB2F55E99C08.taxon	etymology	Etymology. The adjective crypticus refers to rather unremarkable external features that make this species difficult to distinguish from a more common C. nagoanus.	en	Jałoszyński, Paweł (2025): A new species and new records of Cephennomicrus Reitter on the island of Okinawa (Coleoptera, Staphylinidae, Scydmaeninae). Zootaxa 5620 (3): 493-500, DOI: 10.11646/zootaxa.5620.3.9, URL: https://doi.org/10.11646/zootaxa.5620.3.9
03F4D8397C04C35AFF03FB2F55E99C08.taxon	discussion	Remarks. Adults of this species are externally most similar to C. nagoanus; they can be distinguished by a much stronger and denser punctures on the pronotal disc and a slightly narrower pronotum in relation to elytra. The long and medially looped tubular structure in the endophallus of C. crypticus is unique and allows for unambiguous identification. Among congeners that belong to the C. taiwanensis group, no other species has the tubular endophallic structure shaped like the one in C. crypticus; if it forms a loop (in four other species), its placement and / or shape are clearly different (see Jałoszyński, 2009 b: figs 21 – 32).	en	Jałoszyński, Paweł (2025): A new species and new records of Cephennomicrus Reitter on the island of Okinawa (Coleoptera, Staphylinidae, Scydmaeninae).

03F4D8397C06C35CFF03FA0050B699FC.taxon	discussion	Remarks. This species was previously recorded from Mt. Nago-dake, Nago Castle Site in Nago City, and Nekumachiji-dake north-east of Nago City. New records demonstrate that this is most likely the most common and broadly distributed species of Cephennomicrus in the northern region of Okinawa-jima. Moreover, collecting more specimens than those previously known made it possible to compare females with males and identify the former. All newly recorded specimens were collected by sifting leaf litter and rotten wood followed by extraction using a Winkler apparatus. The aedeagus of this species (Figs 13 – 15) is relatively delicate and prone to distortions during preparation; slightly erected aedeagi (Fig. 15) must be carefully studied to identify displaced endophallic components (Fig. 13).	en	Jałoszyński, Paweł (2025): A new species and new records of Cephennomicrus Reitter on the island of Okinawa (Coleoptera, Staphylinidae, Scydmaeninae).

03F4D8397C00C35CFF03FEED52A29A2C.taxon	discussion	Remarks. This is one of two Okinawan Cephennomicrus species described based on specimens collected not in the northern, but in the southern half of the island (in Chibana), on the southern border of the northern forest. The type series (6 exx.) has been collected by a flight intercept trap. The newly recorded specimens were collected by sifting leaf litter and rotten wood and extraction by Winkler apparatus. The two new records demonstrate that C. disjunctus is distributed also in the northern region.	en	Jałoszyński, Paweł (2025): A new species and new records of Cephennomicrus Reitter on the island of Okinawa (Coleoptera, Staphylinidae, Scydmaeninae).

03F4D8397C00C35CFF03FCDD52B99C5B.taxon	discussion	Remarks. This is one of two Okinawan Cephennomicrus species previously known only from the southern half of the island (Chibana), the same area where C. disjunctus occurs. The holotype has been collected by a flight intercept trap, and the paratype by sifting leaf litter. All newly recorded specimens were collected by sifting leaf litter and rotten wood and extraction by Winkler apparatus. The two new records demonstrate that C. disjunctus has a broader distribution and also occurs in the north.	en	Jałoszyński, Paweł (2025): A new species and new records of Cephennomicrus Reitter on the island of Okinawa (Coleoptera, Staphylinidae, Scydmaeninae).
