Species of the genus Nesolotis Miyatake (Coleoptera: Coccinellidae: Sticholotidinae) endemic to China are reviewed, and the genus is removed from synonymy of Sticholotis Crotch. The following eight species are described as new to science: N. magnipunctata Wang et Ren, sp. nov., N. gladiiformis Wang et Ren, sp. nov., N. denticulata Wang et Ren, sp. nov., N. nigra Wang et Ren, sp. nov., N. centralis Wang et Ren, sp. nov., N. quadratimaculata Wang et Ren, sp. nov., N. cordiformis Wang, Ren et Chen, sp. nov. and N. daweishanensis Wang, Ren et Chen, sp. nov. A diagnosis of the genus and a key to known species from China are also provided.
The Australian species classified in the cosmopolitan genus Scymnus are revised. Nomenclatural history, diagnoses, illustrations and distribution are provided for each of the eleven recognized species. Scymnus fuscatus Boheman, 1859 is recorded from Australia for the first time. Four new species, Scymnus alligator, S. bunya, S. leai and S. tasmanicus are described. Lectotypes are designated for: Midus pygmaeus Blackburn, 1892, Scymnomorpha duplopunctulata Blackburn, 1892, Scymnus ambulans Blackburn, 1895, S. mitior Blackburn, 1895, S. parallelus Blackburn, 1889, S. queenslandicus Blackburn, 1892 and S. varipes Blackburn, 1895. A new name Scymnus blackburni nom. nov. is introduced for Scymnus pygmaeus (Blackburn, 1892) preoccupied by Scymnus pygmaeus (Fourcroy, 1785). Scymnus varipes Blackburn, 1895 is recognised as a junior synonym of Scymnus ambulans Blackburn, 1895 (syn. nov.)
Species of Anisorcus Crotch are revised, diagnosed and illustrated. Notes on the genus and nomenclatural history for each species are provided. Lectotypes are designated for Anisorcus affinis Crotch and Anisorcus fryi Crotch. Anisorcus malayanus Crotch is recorded from Solomon Islands and Vanuatu for the first time. Keys to Australasian genera of Chilocorini and to Anisorcus species are presented.

Two new species of Monocoryna (Coleoptera: Coccinellidae: Monocorynini) are described from the Philippines, Mindanao: Monocoryna nicolebertiae sp. nov. and M. philippinensis sp. nov. Monocoryna borneensis Arrow, 1926 is synonymized with Monocoryna moultoni (Sicard, 1913), and Monocoryna javanica Miyatake, 1988 with Monocoryna decempunctata Gorham. The lectotypes of Walteria (=Monocoryna) antennalis Sicard, 1913 and M. borneensis Arrow, 1926 are designated. A catalogue of all known Monocoryna is provided.
The Australian members of the coccinellid tribe Sticholotidini are revised. The tribe in Australia consists of the genus Sticholotis Crotch and a new monotypie genus Chaetolotis gen. nov. (type species: Ch. amy sp. nov.) and is restricted in its distribution to the tropical and subtropical parts of Queensland and coastal New South Wales. Nesolotis Miyatake, 1966 and Paranesolotis Hoang, 1982 are synonymised with Sticholotis Crotch, 1874 (new synonyms). Among five currently recognized species of Sticholotis in Australia, three are described as new (S. culleni, S. cooloola, S. tozer). Gymnoscymnus explanatus Blackburn, 1895 is synonymised with G. quadrimaculatus Blackburn, 1892 (=Sticholotis quadrimaculata). The lectotypes are designated for: Gymnoscymnus explanatus Blackburn and Sticholotis redimita Weise. Nomenclatural history, diagnoses and distribution are provided for each species. Keys to the genera and species are also presented.
Sticholotidini (Coleóptera: Coccinellidae) from Western Ghats, a designated biodiversity hotspot in India, are poorly known. Fourteen species of Sticholotidini from southern Indian plantations, Western Ghats, are treated here. Most of these species are endemic to Western Ghats and are not commonly seen in collections and there is little information on their habitat / biology. Diagnostic information on these species is given here with illustrations of male genitalia wherever possible to facilitate their identification. Sticholotis húmida sp. nov. is described and illustrated. Lectotypes are designated for Orcus (?) ferrugineus Gorham (1894), Clanis binotata Gorham (1894), Sticholotis cribellata Sicard (1910), Sticholotis obscurocincta Sicard (1911), Sticholotis obscurella Weise (1908), Sticholotis nilgiriensis Weise (1908), and Sticholotis tredecimmaculata Weise (1908). Synonychimorpha immaculata Poorani (2003) is reduced to a new junior synonym of S. chittagongi (Vazirani, 1983) (new synonym). A checklist of Sticholotidini known from the Western Ghats is given.
Demographic toxicology is recommended for toxicity determination of the long term effects of a pesticide since it gives a more accurate and efficient measure of the effect of a pesticide. Thus, in the current study the sublethal effects of pirimicarb (carbamate insecticide) two concentrations of LC30 and LC10 were used against third instar larvae of Hippodamia variegata (Goeze) in order to determine the effects of the pesticide on demographic parameters of the predator under laboratory conditions. Results showed that pirimicarb did not affect individual life parameters such as development time of larva, pupa, adult longevity, female and male longevity, adult preoviposition period (APOP), and total preoviposition period (TPOP). However, population parameters such as intrinsic rate of increase (r), net reproductive rate (R0), mean generation time (T), and finite rate of increase (λ) was affected by sublethal treatment. For example, intrinsic rate of increase (r) was 0.18 day–1 in the controls but it was 0.13 and 0.14 day–1 in the treated insects with LC10 and LC30 concentrations, respectively. Also, there were significant differences between mean generation time (T) of the treatments and the controls i.e. mean generation time of the controls was 29.03 days while mean generation time in the two treatments of LC10 and LC30 was 33.93 and 31.66 days, respectively. The finite rate of increase was also significantly affected by sublethal effects of the pesticide. The results showed that pirimicarb, even at low concentrations, has potential to adversely affect the predatory ladybird, therefore care should be taken when this insecticide is used in the Integrated Pest Management (IPM) program.
The subgenus Scymnus of Scymnus Kugelann, 1794 from China is revised. Fifty-six species of the subgenus Scymnus known to occur in China, including twenty seven new species are documented: Scymnus (Scymnus) impolitus sp. nov., S. (S.) obesus sp. nov., S. (S.) zhangmuensis sp. nov., S. (S.) byssinus sp. nov., S. (S.) makuensis sp. nov., S. (S.) extumidus sp. nov., S. (S.) comosus sp. nov., S. (S.) choui sp. nov., S. (S.) trachypus sp. nov., S. (S.) deltatus sp. nov., S. (S.) leigongicus sp. nov., S. (S.) arciformis sp. nov., S. (S.) luxiensis sp. nov., S. (S.) acerbus sp. nov., S. (S.) pingqianensis sp. nov., S. (S.) deflexus sp. nov., S. (S.) plautus sp. nov., S. (S.) xiongfeii sp. nov., S. (S.) recavus sp. nov., S. (S.) nabangicus sp. nov., S. (S.) fasciculatus sp. nov., .S. (S.) fusinus sp. nov., S. (S.) guniujiangicus sp. nov., S. (S.) caiyanghensis sp. nov., .S, (S.) serratus sp. nov., S. (S.) biconvexus sp. nov., and S. (S.) clavellatus sp. nov. Scymnus (Scymnus) sufflavus Canepari, 1997 and S. (S.) trisulicus Canepari, 1997 are recorded from China for the first time. Nomenclatural history, diagnoses, illustrations and distribution are provided for fifty-five recognized species. A key to the species from China is presented.
In the present, the second part of the series titled “Beetles (Coleoptera) of the Rogów region” presents a family of ladybirds (Coccinellidae), as one of the better-known families of beetles occurring in the Rogów area. The faunistic data of presented species enriched by bionomical informations. In addition, the study showed a new species of ladybird for the Polish fauna and it is Nephus (B.) bisignatus (Boh.).
