The subfamily Trigonurinae Reiche, 1866 is a monogeneric subfamily of the large family Staphylinidae with an Holarctic distribution. The genus was the subject of a revision (Blackwelder, 1941). Seven species are known from northern America (Blackwelder, 1941; Herman, 2001), two species from the western Palaearctic and two, recently described species from China (Schülke & Smetana, 2015; Kishimot...

Two fossil species, Paraphloeostiba electrica sp.n. and Phyllodrepa antiqua sp.n. (Staphylinidae, Omaliinae), are described from Baltic amber. Their external and relevant internal structures are illustrated using propagation phase contrast synchrotron microtomography. The palaeobiogeogaphy of the two genera, the thermophilous Paraphloeostiba, the temperate Phyllodrepa, as well as palaeoenvironm...

The first fossil of the staphylinine tribe Diochini Casey is described and figured from an inclusion in mid-Eocene (Lutetian) Baltic amber. Diochus electrussp. n. is distinguished from its congeners and the diversity of rove beetles (Staphylinidae s.l.) is summarized briefly.

Lobrathium fuscoguttatum sp. n. (type locality: Guangxi) is described and illustrated. The latest key to the Lobrathium species of mainland China is modified to include the new species. Additional data are provided for six previously described species.

Quedius (Raphirus) spencei Jacobs and Bergeron, new species, (Coleoptera: Staphylinidae), is described based on specimens from two localities (type locality: 35 km. E Dixonville, Alberta, Canada) in the Boreal Forest. Male genitalia are illustrated, compared with congeners (Q. rusticus Smetana and Q. simulator Smetana) in the Aenescens species group, and included in a slightly modified key to t...

Two new genera and two new species of Aleocharinae (Staphylinidae) from Malaysia are described: Parawroughtonilla Maruyama, gen. n. (type species: Parawroughtonilla hirsutaMaruyama, sp. n.), Leptogenonia Maruyama, gen. n. (type species: Leptogenonia roslii Maruyama, sp. n.), which are associated with Leptogenys borneensis Wheeler, 1919. They are closely related and share a unique character stat...

rove beetle dermatitis produced by the family staphylinidae genus paederus has world- wide distribution some one hundred species of paederus have been found, but it is believed that only 30 of these produce dermatitis. up to 1976 three species of paederus have been found in iran as: p. fusciped curtis; p. pietschmanni bershaner , and p. spectabilis kraatz . observations on the biology of paeder...

Iotarphia rufobrunnea Lee & Ahn, sp. n. is described from Tasmania. The new species is compared with another species of the genus, Iotarphia australis Cameron. A description, habitus photograph and illustrations of the diagnostic characters are provided.

Two new species, Batricavus abdominalis Yin & Li, sp. n. and Batricavus hainanensis Yin & Li, sp. n. are described from Hainan, South China, with male habitus and major diagnostic features illustrated. Batricavus tibialis Yin & Li is newly recorded from Zhejiang, East China. Keys to both sexes of the genus are included.

Lesteva (s.str.) hartmanni sp. n. (Nepal: Gandaki Province, Manaslu Mts.), L. (s.str.) brevipennis Cameron, 1941 and L. (s.str.) torrentum Cameron, 1924 are (re-) described and illustrated. New records of L. (s.str.) championi Lohse, 1982, L. (s.str.) jaegeri Shavrin, 2012 and a modified identification key to the species of Lesteva Latreille, 1797 of Nepal are provided. L. brevipennis is record...
