The Stenothemus harmandi species-group has 10 species at present. They are S. harmandi (Bourgeois, 1902) (located in N. India, Nepal); S. holosericus Švihla, 2005, S. orbiculatus Švihla, 2005 and S. subnitidus Švihla, 2005 (N. India); S. distortirudis Y. Yang & X. Yang, 2014, S. laticollis Y. Yang & X. Yang, 2014, S. parallelus Y. Yang & X. Yang, 2014 and S. septimus Y. Yang & X. Yang, 2014 (China: Xizang); S. fugongensis Y. Yang & X. Yang, 2014 (China: Yunnan) and S. leishanensis Y. Yang & X. Yang, 2014 (China: Guizhou). In the present study, two previously-known species are classified into this species-group, S. dentatus Wittmer, 1974 and S. alexandrae Švihla, 2004, of which the latter as a subspecies of the former is upgraded to the specific level and another two new species are discovered and described. Two new species of the Stenothemus harmandi species-group are described, S. acuticollis sp. n. (China: Yunnan) and S. nigricolor sp. n. (China: Xizang), which are illustrated with habitus photos and aedeagi of males, abdominal sternites VIII and internal genitalia of females. S. alexandrae Švihla, 2004 stat. n. is upgraded from a subspecies of S. dentatus Wittmer, 1974 and the two species are classified into this species-group. Characters of the female reproductive system are described for the first time for the following species: S. distortirudis Y. Yang & X. Yang, 2014; S. laticollis Y. Yang & X. Yang, 2014; S. leishanensis Y. Yang & X. Yang, 2014; S. orbiculatus Švihla, 2005; S. septimus Y. Yang & X. Yang, 2014 and S. subnitidus Švihla, 2005. Meanwhile, some additional distribution information is added for previously-described species. A key for the identification of all species is updated.

AbstractThree known and two new species of Aphanolaimus are described, viz. A. louisae, A. seshadrii, A. brasiliensis, A. aberrans sp. n. and A. vietnamicus sp. n. New data on the morphology and distribution of A. louisae, A. seshadrii and A. brasiliensis are given. The male of A. brasiliensis is described for the first time: it is characterised by the presence of one pair of neck setae, four tubular supplements, two precloacal and six caudal setae, 13-18 μm long spicules with oval manubrium and gradually narrowing shaft, platelike gubernaculum. Aphanolaimus aberrans sp. n. is characterised by a 495-681 μm long body, longitudinally striated cuticle, presence of 24-34 lateral epidermal glands, weakly sclerotised stoma, amphid with central elevation, lateral field starting on the third to seventh annule, oval ventral gland cell; female reproductive system with developed spermathecae, straight vagina without sclerotisations; male with one pair of neck setae, with two or three small tubular supplements and three or four caudal setae, 13-18 μm long spicules with oval manubrium and gradually narrowing shaft, plate-like gubernaculum. Aphanolaimus vietnamicus sp. n. is characterised by a 544-569 μm long body, longitudinally striated cuticle, presence of 19 lateral epidermal glands, weakly sclerotised stoma, amphid with central elevation, lateral field starting on 14th-18th annule, oval ventral gland cell; female reproductive system with developed spermathecae, straight vagina without sclerotisations; male with one pair of neck setae, with two tubular supplements and four caudal setae, 12 μm long spicules with oval manubrium and gradually narrowing shaft.

The species of Stenothemus Bourgeois, 1907 from Southwest China are reviewed. Three species are transferred to this genus, S. davidi (Pic, 1926) comb. nov. (from Malthacus Kirby, 1837), S. minutissimus (Pic, 1933) comb. nov. (from Micropodabrus Pic, 1920) and S. singularicollis (Pic, 1933) comb. nov. (from Lycocerus Gorham, 1895). Two new synonyms are suggested, S. dinshuiensis Švihla, 2011 syn. nov. is synonymized with S. davidi and S. melleus Švihla, 2005 syn. nov. with S. singularicollis. Stenothemus shaanxiensis Švihla, 2004 stat. nov. is raised to species level from a subspecies of S. benesi Švihla, 2004. Five new species are described, S. gracilis Y. Yang & X. Yang sp. nov., S. chongqingensis Y. Yang & H. Liu sp. nov., S. flavicollis Y. Yang & S. Ge sp. nov., S. jindraimimus Y. Yang & X. Yang sp. nov. and S. laticornis Y. Yang & H. Liu sp. nov., which are illustrated with photographs of habitus, aedeagi, abdominal sternites VIII and internal genitalia of the female. Characters of the female reproductive system are described for the first time for the following species: S. diffusus Wittmer, 1974, S. dundai Švihla, 2004, S. grahami Wittmer, 1974, S. jindrai Švihla, 2004, S. tryznai Švihla, 2004 and S. singularicollis.

The E. ovina group of species is proposed here to include Edessa ovina Dallas, 1851 from Trinidad and Tobago, Colombia, Paraguay, Brazil, Argentina (new records) and Guyana; E. impura Bergroth, 1891 from Brazil and Argentina (new record); E. sahlbergii Stål, 1872 restricted to Brazil; and E. graziae sp. nov. from Brazil and Argentina. The E. ovina group can be identified by the apex of the second pair of wings narrowing distally and by a tumid area on the ventral surface of the pygophore (male genitalia) projected posteriorly. Descriptions, measurements, and illustrations of the metasternal process, external and internal genitalia of male and female are provided. A map with the distribution of the species is presented. The holotype of Edessa ovina is designated here. Edessa argali Breddin, 1903 is considered a junior synonym of E. impura. Females of E. ovina and E. impura, and male of E. sahlbergii are described for the first time.

The Chinese fauna of Themus Motschulsky, 1858 is studied. Two new species are described: Themus (Haplothemus) quadratiformis sp. nov. (China: Shaanxi) and T. (H.) longideverticulum sp. nov. (China: Yunnan). Themus (Haplothemus) mishmiensis Wittmer, 1973 stat. nov. is elevated to the full-species rank from the subspecies of T. (H.) elongatior Pic, 1955, both species are redescribed. The male of T. (H.) quadratus Wittmer, 1983 and the female of T. (H.) weishanensis Kopetz, 2016 are described for the first time. The species are illustrated with aedeagus and habitus of male, abdominal sternite VIII and internal genitalia of female.

Two new species of the genus Agrisius Walker, 1855, A. orhanti Volynkin, Dubatolov & Kishida, sp. n. and A. leloii Volynkin, Dubatolov & Kishida, sp. n. are described from South Laos and Vietnam respectively. A. orhanti sp. n. belongs to the A. japonicus Leech, 1889 species-group. Whereas, the male genitalia structure of A. leloii sp. n. is intermediate between those of the A. japonicus and the A. guttivitta Walker, 1855 species-groups, therefore, it is assigned to a separated species-group (the A. leloii species-group). Agrisius dubatolovi Orhant, 2012 is downgraded as a subspecies of A. japonicus: Agrisius japonicus dubatolovi Orhant, 2012, stat. nov. Female genitalia of species of the A. japonicus and most of the A. guttivitta species-groups are illustrated for the first time.

Two new species of the tribe Helopini (Coleoptera: Tenebrionidae) are described from Turkey: Nalassus (Nalassus) becvari sp. nov. (Elazığ Province) and Hedyphanes (Hedyphanes) kmenti sp. nov. (Artvin Province). The first species is characterized by strongly thickened antennomeres 2–8 and differs from all Turkish Nalassus s. str. Mulsant, 1854 in the ventral aspect of eye, which bears a weak posterior ventral impression (rather than a distinct groove of other species). The second species belongs to the species group with asperate punctation of the prothoracic hypomera and differs from all Hedyphanes Fischer von Waldheim, 1820 in the presence of suberect pubescence on both sides of elytral base. Distribution of some Helopini (the Helops genus-group, subtribe Helopina) from Anatolia and Cyprus is updated with new data. Hedyphanes mannerheimi Faldermann, 1837 is recorded for Turkey (Iğdır Province) for the first time. Helops caeruleus caeruleus Linnaeus, 1758 from Pervolia is a new record for Cyprus and the occurrence is probably a result of anthropogenic introduction.
