Frequent biodiversity sampling and monitoring programs often lead to relevant taxonomic findings. Here, as a product of different field expeditions to two places in the northern Andes, we discover and describe two new species of rain frogs of the genus Pristimantis from the cloud forests of the Central Cordillera of Colombia. Pristimantis chocolatebari sp. nov. is diagnosed by having the following character states: dentigerous process of vomer triangular, snout large and protruding, dorsum smooth, vocal slits and vocal sac present, groin and hidden part of the thighs yellow. Pristimantis carylae sp. nov. is diagnosed by having iris copper red, dentigerous process of vomer oval, snout short and rounded, dorsum finely shagreen with scattered tubercles, double nuptial pad in males, groin and hidden part of thighs pink. We also infer, for the first time, the phylogenetic position of P. permixtus, P. platychilus, and two candidate new species. In addition, we emphasize not to use genetic distance as the only source of evidence for species delimitation, considering the high intraspecific diversity found in one of the species described here. Finally, we highlight the relevance of different habitat and ecosystem conservation strategies to promote amphibian diversity studies in the Andes.

Recent studies have highlighted the underestimated diversity of the genus Diploderma Hallowell, 1861 in the Hengduan Mountain Region in Southwest China, but much of the region remains poorly surveyed for reptile diversity. In this study we describe two new species of Diploderma from the upper Jinsha and middle Yalong River Valley, based on evaluations of morphological, genetic, and distribution data. The two new species are morphologically most similar to D. angustelinea and D. vela, but they can be diagnosed from both recognized taxa and all remaining congeners by a suite of morphological features, particularly the distinct coloration of gular spots. Additionally, both new species either render other recognized species paraphyletic or are allopatric with respect to their morphologically similar congeners. Furthermore, we rediscover D. brevicaudum in the wild for the first time, which was known from historical museum specimens only. We estimate the phylogenetic position of D. brevicaudum within the genus Diploderma based on mitochondrial genealogy, and we provide an expanded diagnosis and comparisons against closely related congeners and provide a detailed description of coloration in life based on newly collected specimens. Our discoveries of the new Diploderma species further highlight the urgent conservation needs of the currently neglected hot-dry valley ecosystems in the Hengduan Mountain Region of China.

The Sierra de Maigualida is a poorly explored mountain range in the central Guayana Shield with high levels of endemism. In the present installment, this area is further delimited and mapped, toponymy is reviewed, and the genus Ilex L. is locally reviewed, with two species, namely I. huberi J.R.Grande sp. nov. and I. maigualidensis J.R.Grande sp. nov., described as new to science. Ilex huberi sp. nov. can be distinguished by its leaf blades strongly revolute, mucronate, and with obscure secondary venation, simple dichasia, and depressed-lunate sepals; I. maigualidensis sp. nov. by its dull leaves, flowers with undeveloped styles, and capitate-subcoronate stigmata. Stem buds and cataphylls are proposed as useful characters in species delimitation within the genus, while I. magnifructa Edwin is illustrated for the first time. A key is presented to differentiate all the species of Ilex of the Sierra de Maigualida.

During surveys for the potential biocontrol agents Merochlorops species complex (Diptera: Chloropidae), to control the invasive weed Hedychium gardnerianum Sheppard ex Ker Gawl. (Zingiberaceae), two new species of Rhogadopsis Brèthes (Braconidae: Opiinae) viz., R. gratia Gupta & van Achterberg, sp. n. and R. macrusa Gupta & van Achterberg, sp. n. were reared as solitary larval-pupal parasitoids of Merochlorops in the stems of H. gardnerianum. Interestingly, both wasp species have very different ovipositor lengths, in addition to other characters for species delimitation. Perhaps parasitism by the respective wasp species depends on the thickness of the stem harbouring the chloropid larvae. In the present study, both these new species of wasps are described and illustrated, together with notes on their biology. For the first time the genus Rhogadopsis has been found associated with Chloropidae; earlier records concern Agromyzidae.

Spiders of the genus Clubiona Latreille, 1804 from Xishuangbanna, Yunnan Province, China are studied. A total of 47 species is reported and illustrated, including 14 new species and two new synonyms. Twelve of the new species belong to four species groups: C. dengpao Yu & Li, sp. nov., C. subdidentata Yu & Li, sp. nov., C. tixing Yu & Li, sp. nov., C. xiaoci Yu & Li, sp. nov., C. xiaokong Yu & Li, sp. nov., C. yejiei Yu & Li, sp. nov., C. zhaoi Yu & Li, sp. nov. and C. zhigangi Yu & Li, sp. nov. from the C. corticalis group; C. mii Yu & Li, sp. nov. and C. subtongi Yu & Li, sp. nov. from the C. ternatensis group; C. banna Yu & Li, sp. nov. from the C. filicata group; and C. menglun Yu & Li, sp. nov. from the C. trivialis group. The remaining two new species, C. shuangsi Yu & Li, sp. nov. and C. wangchengi Yu & Li, sp. nov., are not readily assignable to any of the existing species groups. The female of C. cochlearis Yu & Li, 2019, the female of C. tiane Yu & Li, 2019, the female of C. bicornis Yu & Li, 2019, the male of C. lala Jäger & Dankittipakul, 2010 and the true female of C. suthepica Dankittipakul, 2008 are described for the first time. Two new synonyms are: C. vukomi Jäger & Dankittipakul, 2010 syn. nov. = C. circulata Zhang & Yin, 1998; C. melanothele Thorell, 1895 syn. nov. = Clubiona melanosticta Thorell, 1890. A checklist of Clubiona species from Xishuangbanna is provided. The DNA barcodes of almost all of the species were obtained for species delimitation, matching of sexes and future use.

The family Hahniidae is reported from Thailand for the first time. The genus Hexamatia gen. nov. and two new species, Hexamatia seekhaow gen. et sp. nov. and Hahnia ngai sp. nov., are described and illustrated. DNA sequences are provided for all the species reported here. The phylogenetic position of the novel genus Hexamatia gen. nov. and its relation to Hahnia are discussed. Based on these results, a new combination is proposed for Hexamatia senaria (Zhang, Li & Zheng, 2011) gen. et comb. nov. = Hahnia senaria. Known distribution of the species Hahnia saccata Zhang, Li & Zheng, 2011, originally described from China, is expanded. A brief review and notes on the taxonomy of the six-eyed hahniids are included.

The genus Sphaerocetum Fikáček, 2010 is reviewed on the basis of specimens collected from mixed ant nests shared by Camponotus Mayr, 1861 and Crematogaster Lund, 1831 ants in Peninsular Malaysia. Two new species, S. arboreum, sp. nov. and S. hortulanum, sp. nov., are described. A larva of S. arboreum was collected in the same nest as the adults, implying that it is likely that the entire life cycle takes place inside the ant nest; its association with adults was confirmed by cox1 sequences. It is described in detail and represents the first known larva of the tribe Protosternini. Fragments of four genes (cox1, cox2, 18S and 28S) were amplified for S. arboreum and combined with previously generated data in order to test the position of the genus within the subfamily Sphaeridiinae. The analyses revealed Sphaerocetum as a sister taxon to Protosternum Sharp, 1890, corroborating the monophyly of the tribe Protosternini. Bayesian analysis revealed an alternative hypothesis of the phylogenetic position of the tribe, indicating that Protosternini is a sister-group to Omicrini. This position is supported by the chaetotaxy of the maxillary stipes of the larva, which lacks the increased number of stout setae on the inner face present in all other Sphaeridiinae larvae except Omicrini.

In this paper, M. yanomami n. sp., from Brazilian Amazonia, Chaetacis bandeirante n. sp., from Central Brazil, and the males of M. gaujoni Simon, 1897 and M. ruschii (Mello-Leitão, 1945) n. comb. , respectively from Ecuador and Brazil, are described and illustrated for the first time. An ontogenetic series of the last development stages of both sexes of Micrathena excavata (C. L. Koch, 1836) is illustrated and briefly described. Adult females are larger and have longer legs and larger abdomens than adult males. Probably females undergo at least one additional moult before adulthood, compared to males. Micrathena ornata Mello-Leitão, 1932 is considered a junior synonym of M. plana (C. L. Koch, 1836), and M. mastonota Mello-Leitão 1940 is synonymized with M. horrida (Taczanowski, 1873). Acrosoma ruschii Mello-Leitão, 1945 is revalidated, transferred to Micrathena and considered a senior synonym of M. cicuta Gonzaga & Santos, 2004. Chaetacis necopinata (Chickering, 1960) is recorded for Brazil for the first time. Chaetacis incisa (Walckenaer, 1841) is considered a nomen dubium.

This paper provides a comprehensive check list of Nolinae species recorded in Hong Kong, China based on the collections of the second author, Dr. Roger Kendrick and the Natural History Museum, London. The checklist comprises 30 species.  Two of them are new to science and described here as new species (Spininola kendricki sp. n., and Hampsonola ceciliae sp. n.). Misidentification of the female paratype of Spininola nepali László, Ronkay & Ronkay, 2014 is revealed and the true female of S. nepali is illustrated with its genitalia described here for the first time. The hitherto unknown female of S. armata László, Ronkay & Witt, 2010 is also illustrated here for the first time. All species recorded from Hong Kong are illustrated together with their genitalia on 54 colour and 46 black and white diagnostic figures.
