Schuelkelia gen. n., a new eastern Palaearctic ant-like stone beetle, with synopsis of Eurasian genera of Cyrtoscydmini (Coleoptera: Staphylinidae: Scydmaeninae).

Schuelkelia unicornis gen. & sp. n. is described from Yunnan, China. The new taxon belongs to a group of genera characterized by the submentum lacking lateral sutures, and is most similar to Euconnus. Among the Eurasian genera Schuelkelia can be easily identified on the basis of the broad occipital constriction, pronotum lacking antebasal pits or grooves, elytra lacking externally visible basal foveae; mesoscutellum not visible between elytral bases; long and slender but weakly elevated mesoventral intercoxal process, and other features which are described and illustrated in detail. Morphological structures of Schuelkelia are compared with those of all other Palaearctic and Oriental Cyrtoscydmini, and keys to identification of all Eurasian and separately Chinese genera of Cyrtoscydmini are given. A brief illustrated synopsis of all genera of Cyrtoscydmini known to occur in the Oriental and Palaearctic regions is given, to facilitate identifications and future studies.

A new Cephennium of Kyrgyzstan, with notes on subgenera and distribution (Coleoptera, Staphylinidae, Scydmaeninae)

Cephennium chirgisianum sp. n. of western Kyrgyzstan is described. This is the easternmost known locality where this predominantly western European genus occurs. This new species is not placed in any subgenus, and problems with subgeneric diagnoses and systematics of Cephennium are discussed. The distribution of Cephennium is summarized and possible dispersal routes or areas where this genus can be expected to occur are indicated.

Confused identity: subgenera of Pseudoeudesis Binaghi belong in two tribes (Coleoptera: Staphylinidae: Scydmaeninae)

Afroeudesis Franz and Oreoeudesis Franz, Afrotropical subgenera of Pseudoeudesis Binaghi (Scydmaenini), are elevated to the genus rank and transferred to Cyrtoscydmini. The East Palaearctic genus Nanoscydmus Jałoszyński is reduced to a subgenus of Afroeudesis stat. n., resulting in Afroeudesis (Nanoscydmus) baoshanus (Jałoszyński), comb. n. and Afroeudesis (Nanoscydmus) nepalensis (Jałoszyński), comb. n. Morphological structures of the type species of Afroeudesis and Oreoeudesis are illustrated and described in detail, and the following species are redescribed: Afroeudesis (s. str.) basilewskyi Franz (Tanzania), Oreoeudesis lindneri Franz (Tanzania), Oreoeudesis aberdarensis Franz (Kenya) and Oreoeudesis camerunensis Franz (Cameroon).

Late-instar larva of Scydmaenus (Parallomicrus) rufus Müller & Kunze (Coleoptera: Staphylinidae, Scydmaeninae).

The late-instar (most likely the last instar) larva of Scydmaenus (Parallomicrus) rufus is described. A comparative study with other known larvae of Scydmaenus (belonging to Scydmaenus s. str. and the subgenus Cholerus) is carried out and it is concluded that while the general body form and some characters are shared by immature Parallomicrus and Cholerus, there are nevertheless features present in Parallomicrus and Scydmaenus s. str. that are absent in Cholerus. A subcylindrical and strongly elongated body differentiates immature Parallomicrus from Scydmaenus s. str., while the following characters, present in Parallomicrus, are not known in Cholerus: a pair of long lateral setae on head capsule, four (and not five) pairs of dorsoanterior setae on the nasale, more than 10 teeth on the anteroventral margin of nasale instead of five only, three (and not two) solenidia on the antennomere III, three (and not two) pairs of labial setae, slightly (and not strongly) elongate abdominal segment IX, and abdominal segment X not constricted near base.

Notes on the systematic placement of Sciacharis ( Anthicimimus ) (Coleoptera: Staphylinidae: Scydmaeninae)

The entangled history of Sciacharis Broun, 1983, a genus in which nearly 240 species were placed by Herbert Franz who has apparently never studied its type species, was recently summarized by Jaloszynski (2014a, b). A synonymy of Chatchamaenus Franz with Sciacharis s. str. was demonstrated, and Maorinus Franz, 1980 was placed as a subgenus of Sciacharis (Jaloszynski 2014a). Still, the systematics of Sciacharis , a genus currently comprising nearly 300 species and distributed in the Southern Hemisphere, is far from clarity.

The Cephenniini of China. VII. New species and new records of Cephennodes Reitter of Shaanxi, Gansu and Sichuan (Coleoptera: Staphylinidae: Scydmaeninae)

Nine new Chinese species of Cephennodes are described: C. (s. str.) intricatus sp. n. (Gansu), C. (s. str.) cryptointricatus sp. n. (Gansu), C. (s. str.) monofoveatus sp. n. (Shaanxi), C. (s. str.) pinnapes sp. n. (Sichuan), C. (s. str.) elegantissimus sp. n. (Sichuan), C. (s. str.) palpalis sp. n. (Gansu), C. (Fusionodes) corpulentus sp. n. (Sichuan), C. (Fusionodes) gutta sp. n. (Shaanxi) and C. (Fusionodes) medusa sp. n. (Sichuan). Cephennodes elegantissimus and C. palpalis are not placed in any species group within Cephennodes, while the remaining new taxa belong to the excavatus group (C. intricatus and C. cryptointricatus), the taurus group (C. monofoveatus), the inflatipes group (C. pinnapes), the graeseri group (C. gutta and C. medusa) and the newly established serratus group (C. corpulentus). Additionally, new records of previously described species are given: C. (s. str.) subcaudatus Jałoszyński (Shaanxi), C. (s. str.) parabdominalis Jałoszyński (Shaanxi) and C. (s. str.) pteroscapus Jałoszyński (Sichuan).

The Cephenniini of China. VI. New species and new records of Cephennodes Reitter from Hainan, Guangxi and Guangdong (Coleoptera: Staphylinidae: Scydmaeninae)

Five new Chinese species of Cephennodes (s. str.) are described: C. bicavatus sp. n. (Guangdong), C. pseudobos sp. n. (Guangxi), C. huapingensis sp. n. (Guangxi), C. elevatus sp. n. (Guangxi), and C. gaozhaianus sp. n. (Guangxi). Cephennodes qiongdaoanus Jałoszyński and C. capricornis Jałoszyński are recorded for new localities in the provinces of Guangxi and Hainan, respectively. Diagnostic characters of all hitherto known representatives of the Cephennodes taurus, Cephennodes bos and Cephennodes impressifrons species groups are compiled.

Taxonomy of the Alloraphes - Stenichnaphes - Parastenichnaphes complex: Stenichnodes complicates the picture (Coleoptera: Staphylinidae: Scydmaeninae)

Examination of the holotype of the type species of Stenichnodes Franz revealed that morphological structures of this Afrotropical genus are nearly identical with those of later described Oriental Parastenichnaphes Franz. Consequently, Parastenichnaphes is reduced to a subgenus of Stenichnodes, resulting in Stenichnodes (Parastenichnaphes) sumatrensis Franz, comb. n. and Stenichnodes (Parastenichnaphes) ceylonensis Franz, comb. n. The subgenus Parastenichnaphes differs from Stenichnodes s. str. in notosternal sutures of the prothorax complete (and not obliterated anteriorly), subtriangular (and not very narrow and carinate) prosternal process and absence of lateral metaventral carinae. Stenichnodes and its type species are redescribed.

Ruthmuelleria, a new genus of Carinodulini (Coleoptera: Coccinellidae: Microweiseinae) from South Africa.

A new genus of ladybird beetles, Ruthmuelleria, belonging to the pantropical tribe Carinodulini, is described based on a new species R. grootdrifensis from South Africa. The genus is diagnosed by the unique 8-segmented antennae and posteriorly-directed metaventral postcoxal lines. A key to the genera and discussion of diagnostic characters of Carinodulini are also included.

Three new species of Neuraphes in eastern Qinghai-Tibet Plateau (Coleoptera, Staphylinidae, Scydmaeninae)

Three new ant-like stone beetle species: Neuraphes (Pararaphes) sichuanus sp. n., N. (P.) tuyuhun sp. n., and N. (P.) miniqinghaiensis sp. n. are described from Sichuan and Qinghai provinces of China. Another species, close to N. qinghaiensis Jałoszyński, is illustrated, but not formally described because of unclear diagnostic characters. The placement of Neuraphes species that inhabit mountain ranges surrounding Qinghai-Tibet Plateau in the subgenus Pararaphes is discussed and their distribution is summarized.
