First description of the females of Qinorapalaqinlingana Chou & Wang, 1995 (Lepidoptera, Lycaenidae) from Shaanxi and Sichuan Provinces, western China.

Background: The family Lycaenidae is a widely distributed and species-rich group with approximately 5300 described species. The rare genus Qinorapala Chou & Wang, with Q.qinlingana Chou & Wang as its type species was established as monotypic. In the original description, Q.qinlingana was described from a male holotype; the female remained unknown. To date, the genus is only recorded from the Qinling Mountains (Shaanxi and Gansu Provinces). In this study, two female specimens, from Shaanxi Province and western Sichuan Province (bordering Yunnan Province) are described and illustrated for the first time. New information: Female specimens of Q.qinlingana from Shaanxi and Sichuan are described for the first time. The species' distribution is updated and a distribution map is provided.

A new species of Tanna Distant, 1905 from Yunnan, China (Hemiptera, Cicadidae, Cicadinae).

Background: The genus Tanna Distant, 1905 (Hemiptera, Cicadidae, Cicadinae, Leptopsaltriini, Leptopsaltriina) currently includes 23 species (three tentatively placed), with its actual geographical distribution in China, Japan, Nepal, Bhutan, Cambodia, Thailand and Vietnam. Most of them, 16 species, are known from China, including one new species here described. New information: A new species of cicada, Tannafengi Wang sp. nov., is described from Yunnan, southwest China. Colour plates are presented to illustrate all diagnostic characters. An updated list of Tanna species occurring in China is provided.

More than half of them, 10 species, are known from China, including one new species, described in the present study. New information: A new species of cicada, Macrosemiafengi Wang sp. nov., is described from Yunnan and Guizhou, southwest China. Colour plates are presented to illustrate its diagnostic characters. The distribution map of the new species is also given.

Two new species of Hesperopenna Medvedev & Dang, 1981 are described from Singapore: H.temaseksp. nov. and H.bakerisp. nov. The specimens of both new species were collected by Charles Fuller Baker and found in the unidentified Galerucinae material deposited in the National Museum of Natural History, Smithsonian Institution, Washington, DC. Hesperopennatemaseksp. nov. is diagnosed by the black extreme elytral suture in the basal third, antennae longer than the body, the structure of the penis, and the last abdominal ventrite with two deep U-shaped incisions in females. Hesperopennabakerisp. nov. is diagnosed by the black tibia and first two tarsomeres, and the structure of the penis.

Melanasterasinica He & Burckhardt, sp. nov., a new psylloid species (Hemiptera, Psylloidea, Liviidae) from China developing on Grewia sp. (Malvaceae).

Melanasterasinica He & Burckhardt, sp. nov., a new psylloid species developing on Grewia sp., is described from Hainan, China. It is the first Melanastera species reported from Asia and China, and the second species from the Old World. While New World species of Melanastera are mostly associated with the plant families Melastomataceae and Annonaceae, the two Old World species develop on the malvaceous Grewia, a host otherwise used in psylloids by two Haplaphalara species. The new species is described, diagnosed and illustrated, and its host plant and biogeographic ranges are discussed.

Biodiversity and Spatiotemporal Variations of Mecoptera in Thailand: Influences of Elevation and Climatic Factors.

Ecological analyses of the small and lesser-known insect order Mecoptera in Thailand are presented. Specimens were collected monthly over a period of 12 consecutive months, using both Malaise and pan traps, from 29 sampling sites located in 18 national parks throughout Thailand. A total of 21 species in four genera were identified from 797 specimens, including Panorpa (1 species), Neopanorpa (18 species), Bittacus (1 species), and Terrobittacus (1 species), with the latter genus representing a new genus record to Thailand. Neopanorpa harmandi, N. siamensis, N. byersi, and N. malaisei were the most abundant species, representing 27.4%, 11.3%, 10.3% and 8.8% of the total specimens, respectively. The species with the highest frequency, as indicated by the high percentage of species occurrence (%SO), was N. siamensis (51%), followed by N. byersi (34%), N. harmandi (34%), N. spatulata (27%), and N. inchoata (27%). Eleven species (52%) exhibited specific regional occurrences. N. tuberosa and N. siamensis had the widest distribution, being found in almost all regions except for western and southern regions for the first and second species, respectively. The seasonal species richness of Mecoptera was high during the rainy season in the northern, northeastern, central, eastern, and western regions, with the highest richness observed in July (15 species), followed by the hot (10 species) and cold seasons (7 species), while there was no significant difference in species richness between seasons in the southern region. Multiple regression models revealed a negative association between species richness and abundance of Mecoptera with both elevation and temperature, and a positive association between rainfall and species evenness. It is predicted that climatic changes will have a detrimental effect on the mecopteran community. The results of this study enhance the understanding of the ecological aspects of Mecoptera, offering crucial insights into its biodiversity and distribution, which are vital for conservation and forest management.

Taxonomic review of Manocoreini with description of a new species from China (Hemiptera, Heteroptera, Coreidae).

In the present paper, all seven species of Manocoreini are reviewed, and a new species Manocoreushsiaoisp. nov. is described from Guangxi, China.

Two new species of the genus Terrobittacus Tan & Hua, 2009 (Mecoptera, Bittacidae).

Two new species of Terrobittacus Tan & Hua, 2009 are described and illustrated from Sichuan and Guangxi provinces of China, increasing the species number of Terrobittacus to eight. Terrobittacusemeishanicussp. nov. is differentiated from its congeners by wings with distinct markings and a female subgenital plate with a V-shaped carina. Terrobittacuslaoshanicussp. nov. can be recognized by the black terga VI-IX. A key to species of Terrobittacus is updated. The species distribution and the relationship between adult morphology and mating behavior were briefly discussed.

Diversity and distribution of the cladocerans (Crustacea, Branchiopoda) in Thailand.

An updated checklist of the cladoceran fauna from inland aquatic habitats in Thailand (a high-diversity hotspot in Southeast Asia), based on published cladoceran records found in literature is presented. The checklist updates nomenclature and species distributions, especially habitat preferences. A total of 138 valid recorded species is relatively high. However, the estimators indicate that more species are expected to be found with more research. The north-eastern and southern regions of Thailand are well-studied regions of high species richness with 100 and 96 cladoceran species, respectively, whereas the northern and eastern regions have large research gaps that should be studied further. Moreover, each habitat type seems to have a unique cladoceran community as the similarity values amongst them are mostly low (Sorensen similarity index < 0.50). Therefore, it is suggested that habitats with unique characteristics, such as peat swamps, stream and cave pools, are worthy of further exploration. If the current records of cladoceran diversity in Thailand confirms a high diversity of this animal in the tropical region, then the geographical distribution of each species can be properly explained.

Two New Species of Cryptolestes Ganglbauer (Coleoptera, Cucujoidea, Laemophloeidae) from the Philippines and Brazil.

Two new species of Cryptolestes Ganglbauer (Coleoptera, Cucujoidea, Laemophloeidae) are described and illustrated in this paper. Cryptolestes cervus sp. nov. from the Philippines and C. subcalabozus sp. nov. from Brazil are compared to their most similar congeners, from which they are distinguished based on the morphology of the male antennal scape. In addition, Cryptolestes beccarii (Grouvelle) is here redescribed based on the newly designated lectotype, with commentaries on the variation of the male antennal scape.
