ABSTRACT
 Aenictus shilintongae, a new army ant from Southeast China, is described based on the worker caste. The new species belongs to the A. laeviceps species group and seems to be closely related to A. rotundicollis Jaitrong et Yamane, 2011 and A. sonchaengi Jaitrong et Yamane, 2011, but is easily distinguished from the latter two in having dense pilosity on head and mesosoma. It is named in honor of Her Royal Highness Princess Maha Chakri Sirindhorn of the Kingdom of Thailand after her name in Chinese.

KEY WORDS: Army ants, Aenictus shilintongae, Taxonomy, China.

[Mammalogy • 2017] A Taxonomic Revision of the Kerivoula hardwickii complex (Chiroptera: Vespertilionidae) with the Description of A New Species, Kerivoula furva, from Taiwan


 Kerivoula furva 
Kuo, Soisook, Ho, Csorba, Wang & Rossiter, 2017

Abstract
Since its discovery, the taxonomic status of the only species of Kerivoula (Chiroptera: Vespertilionidae: Kerivoulinae) to be found on Taiwan has been confused. Previous studies have assigned this species to either Kerivoula hardwickii or K. titania, both of which occur on continental SE Asia. This uncertainty supports repeated suggestions in the literature that specimens of K. hardwickii collected and/or sampled across SE Asia are likely to represent multiple cryptic taxa. To address these issues, we combined new and existing data from the genus Kerivoula on Taiwan and continental Asia, and performed diagnostic analyses in steps. First, phylogenetic reconstructions based on mitochondrial and nuclear DNA revealed a well-supported group comprising all taxa currently recognized as K. hardwickii, together with the Taiwanese Kerivoula and Kerivoula kachinensis to the exclusion of all other congeneric species. Second, focusing on all members of this monophyletic clade (i.e., K. hardwickii complex) together with K. titania, we used multivariate statistical methods to separate taxa based on morphometric data. Our results provide strong evidence that among these bats, the Taiwanese Kerivoula is a new species that also occurs on continental Asia, for which we provide a formal description and name. In addition, we show that the subspecies K. hardwickii depressa should be elevated to species status [Kerivoula depressa]. We discuss our findings and the caveats of this and similar studies.

Summary
Four new species of the pantropical genus Xylopia L. (Annonaceae) in East Africa are proposed. Two of the new species, Xylopia lukei D. M. Johnson & Goyder and X. tenuipetala D. M. Johnson & Goyder, most closely resemble the East African species X. mwasumbii D. M. Johnson. This species group is confined to the lowland coastal dry forests extending from central Tanzania to northern Mozambique. Problems with the circumscription of X. parviflora (A. Rich.) Benth. in eastern Africa are presented. East African plants identified as that species differ in numerous ways from the plants in central and western Africa, and in this paper are distinguished as X. parviflora sensu Verdcourt. Complicating the picture further is the fact that two rare but readily distinguishable species, X. tanganyikensis D. M. Johnson and X. keniensis D. M. Johnson, both described here, have been confused with X. parviflora sensu Verdcourt. The newly described species are narrowly distributed and most sites are threatened by habitat alteration, three of the four species having provisional IUCN conservation assessments of EN B1ab(iii)+ B2ab(iii).

Key Words: Coastal dry forest, endemism, Kenya, Mozambique, Tanzania

Larinia dubia  
Ott & Rodrigues, 2017 


Abstract

The araneid genus Larinia Simon currently includes 56 species, eleven of them with New World distribution (World Spider Catalog, 2016). North American species of the genus were revised first time by Levi (1975) and South American species by Harrod et al. (1991). According to these authors there are four species known from subtropical South America (Larinia bivittata Keyserling 1885; L. montecarlo (Levi, 1988); L. t-notata (Tullgren, 1905); L. tucuman Harrod, Levi & Leibensperger, 1991) and also four species known from tropical South America (L. ambo Harrod, Levi & Leibensperger, 1991; L. directa (Hentz, 1847); L. lampa Harrod, Levi & Leibensperger, 1991; L. neblina Harrod, Levi & Leibensperger, 1991). According to Buckup et al. (2010) a total of 209 species of Araneidae are recorded for state of Rio Grande do Sul, including the three species L. bivittata, L. montecarlo and L. t-notata.

[Crustacea • 2017] Euastacus vesper • A New Giant Spiny Crayfish (Decapoda, Parastacidae) from the Great Dividing Range, New South Wales, Australia


Euastacus vesper
McCormack & Ahyong, 2017

DOI: 10.11646/zootaxa.4244.4.6 

Abstract

Euastacus vesper sp. nov., is described from the upper Cudgegong River, Coricudgy State Forest, New South Wales, Australia. The new species occurs in the western drainage of the Great Dividing Range, and is most closely related to E. spinifer (Heller, 1865), which occurs on the eastern side of the range. Euastacus vesper differs from E. spinifer by its considerably smaller maximum size (OCL 67.9 mm versus 116.7 mm), greater degree of thoracic spination loosely arrayed in three instead of two rows and absence of the antennular basipodite and coxopodite spines. Observations on burrowing, ecological preferences and biology are presented.

Keywords: Crustacea, Euastacus, Parastacidae, spiny crayfish, freshwater, Australia


 Euastacus vesper sp. nov., male paratype (ACP1130), Cudgegong River. 

Etymology. Named vesper (Latin), meaning “western”, alluding to the western distribution of the new species relative to its closest relative, E. spinifer.
Suggested common Name: the Cudgegong Giant Spiny Crayfish

Distribution. Presently known only from the Cudgegong River and its tributaries; 743–1123 m a.s.l.

 DOI: 10.3897/zookeys.660.11780 

Abstract
Laos has large areas of primary forest with a largely unexplored fauna. This is evidenced by millipedes, class Diplopoda, with fewer than 60 species being recorded from the country. In the widespread Southeast Asian “Star Millipede” genus Eutrichodesmus Silvestri, 1910 (family Haplodesmidae), only two of 49 recorded species have been found in Laos. Four new species of Star Millipedes are here described from caves in Laos: Eutrichodesmus steineri Liu & Wesener, sp. n.E. deporatus Liu & Wesener, sp. n., Eparaster Liu & Wesener, sp. n. and Eparvus Liu & Wesener, sp. n.. A fifth species, for which only a female is available, remains unnamed. The defensive glands (ozopores) are found to be strongly or entirely suppressed in two of the new species, E. deporatus Liu & Wesener, sp. n. and E. paraster Liu & Wesener, sp. n., both troglobionts, which is new to the family. All of the Star Millipedes were collected during Northern Lao-European Cave Project faunal surveys conducted by the Senckenberg Museum, Frankfurt. A key to the six species of Eutrichodesmus currently known to occur in Laos is provided.

Abstract
Southeast Asia is one of the most geologically dynamic regions of the world with great species diversity and high endemism. We studied the bulbuls of the south and southeast Asian genus Iole (Aves: Pycnonotidae) in order to analyse their evolutionary relationships and describe their patterns of diversification and delimit species boundaries. Our phylogeographic reconstruction, based on two mitochondrial and one nuclear markers, sampled from all 13 recognized Iole taxa, presently grouped as four species, revealing three primary lineages: (1) a Palawan lineage (2) a Sundaic group distributed in the Malay Peninsula, Sumatra and Borneo and (3) an Indochinese group distributed throughout continental Southeast Asia. Divergence time estimation suggested that the Palawan lineage diverged during the Miocene (around 9.7 Mya), a later split between the Sundaic and Indochinese lineages occurring around 7.2 Mya. The present classification of Iole based on morphology does not accurately reflect taxonomic relationships within the genus, in which we recognize five more putative species. An integrative approach that incorporates morphology and bioacoustics should further refine our understanding of species limits among Iole taxa.

4.) Baker’s Bulbul (Iole cinnamomeoventris; ยังไม่มีชื่อภาษาไทยอย่างเป็นทางการ) 
- นกชนิดใหม่นี้เดิมถูกจัดเป็นเพียงชนิดย่อยของนกปรอดเล็กตาขาว เนื่องจากมีลักษณะภายนอกใกล้เคียงปรอดเล็กตาขาวมากๆ จนหลายๆครั้งในภาคสนามไม่เห็นความแตกต่าง 
- แต่จากการวิเคราะห์ DNA พบว่ามันมีความแตกต่างในเชิงวิวัฒนาการมากจนสมควรจะแยกเป็นชนิดใหม่ และยังพบว่ามีสายวิวัฒนาการใกล้ชิดกับ ปรอดเล็กสีไพลตาแดง (แทนที่จะใกล้ชิดกับปรอดเล็กตาขาวอย่างที่ถูกจัดไว้เป็นชนิดย่อยเดิม) 
- พบในภาคใต้ของไทย บริเวณด้ามขวานตั้งแต่ราวๆ จ.เพชรบุรีลงไปถึงราวๆ จ.สงขลา

[PaleoEntomology • 2017] Yijenplatycnemis huangi • Extreme Adaptations for Probable Visual Courtship Behaviour in A Cretaceous Dancing Damselfly


Yijenplatycnemis huangi
 Zheng, Nel, Jarzembowski, Chang, Zhang, Xia, Liu & Wang, 2017

Illustration by D. Zheng. DOI: 10.1038/srep44932 

Abstract
Courtship behaviours, frequent among modern insects, have left extremely rare fossil traces. None are known previously for fossil odonatans. Fossil traces of such behaviours are better known among the vertebrates, e.g. the hypertelic antlers of the Pleistocene giant deer Megaloceros giganteus. Here we describe spectacular extremely expanded, pod-like tibiae in males of a platycnemidid damselfly from mid-Cretaceous Burmese amber. Such structures in modern damselflies, help to fend off other suitors as well as attract mating females, increasing the chances of successful mating. Modern Platycnemidinae and Chlorocyphidae convergently acquired similar but less developed structures. The new findings provide suggestive evidence of damselfly courtship behaviour as far back as the mid-Cretaceous. These data show an unexpected morphological disparity in dancing damselfly leg structure, and shed new light on mechanisms of sexual selection involving intra- and intersex reproductive competition during the Cretaceous.

รักตะนิล |  Peperomia sirindhorniana Suwanph. & Chantar.


Summary
Four new species of Peperomia (Piperaceae) from Thailand, namely Peperomia heptaphyllaPeperomia masuthonianaPeperomia multisurcula and Peperomia sirindhorniana are described and illustrated. The reinstatement of Peperomia dindygulensis is also proposed with supporting morphological evidence.

Key words: IUCN vulnerability; morphology; taxonomy


Taxonomic Treatment


• Peperomia heptaphylla Suwanph. & Hodk., sp. nov. 


Type: Thailand, Prachuap Kiri Khan
Etymology. The specific epithet refers to the number of leaves per node.
Vernacular Name: เบี้ยประจวบ - Bia Pra Chuap.


• Peperomia masuthoniana Suwanph. & Chantar. sp. nov. 


Type: Thailand, Chiang Mai, Doi Chiangdao
Etymology: The specific epithet honours Associate Prof. Sumon Masuthon (1952 – present), Department of Botany, Faculty of Science, Kasetsart University, who encouraged the first author to intensively study the family Piperaceae for the Flora of Thailand project.
Vernacular Name: เบี้ยเชียงดาว - Bia Chiang Dao.



• Peperomia multisurcula Suwanph. & Hodk. sp. nov. 
Type: Thailand, Nan
Etymology: The specific epithet refers to the stems that have many clumps, and many main stems and branchlets.
Vernacular Name: เบี้ยสะปัน - Bia Sa Pan (Nan).




• Peperomia sirindhorniana Suwanph. & Chantar., sp. nov. 
Type: Thailand, Loei, Nong Hin, Pha Hin Ngam

Conservation Status. This species is uncommon and only a few specimens have been collected from the border area between Loei and Khon Kaen provinces in northeastern Thailand. The populations are narrowly distributed in an area of karst limestone and not in a protected area. The populations are threatened by farming and deforestation. The status of Peperomia sirindhorniana is assessed as Critically Endangered (CR), according to IUCN (2011) criteria and the authors consider a category of B1b to be appropriate.

Etymology: The specific epithet honours to H.R.H. Princess Maha Chakri Sirindhorn Mahidol who initiated the Plant Genetic Conservation Project to develop the personnel and plant genetics resources for the maintenance of plant varieties, and for the development to be advantageous for farmers and the business sector of Thailand.
Vernacular Name: Rak-Ta-Nil.


Notes:
 We discovered some unidentified specimens (T. Smitinand & H. Sleumer 1131 in BKF and L that were collected from Pha Nok Khao, Khon Kaen province, northeastern Thailand. They are similar to Peperomia pellucida in gross morphology but differ in some characters. We have subsequently collected living specimens from a nearby locality and they are easily recognised as a species new to science. The distinguishing characteristics of P. sirindhorniana are its red or reddish petioles and stems, and its bright to dark green leaves when fresh (subcoriaceous when dry) as opposed to pale green (membranous when dried) in P. pellucida. Furthermore, its fruits are larger than P. pellucida and are ovoid with a beaked apex formed from the style and it has densely acute papillae on the fruit surface.
