A new species of Ptyctolaemus Peters, 1864 is described from Htamanthi Wildlife Sanctuary, Sagaing Division, Myanmar. The new species differs from P. gularis and Ptyctolaemus aff. gularis from Tibet, China, by having relatively longer limbs and different colorations of the gular region, and it differs from P. collicristatus by having much longer limbs and a less developed nuchal crest in males. Moreover, the new species differs genetically from Ptyctolaemus aff. gularis from Tibet, China, and P. collicristatus by an uncorrected percentage distance of 23.5% and 24.8%, respectively, inferred from mitochondrial NADH dehydrogenase subunit 2 gene sequences. This discovery increases the number of known Ptyctolaemus species to three.

A new species of Oligodon Fitzinger, 1826 is described based on specimens collected from Churah Valley of Himachal Pradesh. The new species is related to O. arnensis based on molecular as well as morphological data, however differs from it in several aspects. The new species shows a pairwise sequence divergence of 6–20% from congeners for mitochondrial cytochrome b gene. Lack of pterygoid and palatine teeth of the new species suggests that the diet may largely comprise of eggs. Discovery of the new species is not surprising, as the Western Himalayas has been poorly explored in terms of its herpetofaunal diversity. Considerable genetic divergence in the sampled sequence suggests Oligodon arnensis is a species complex, likely represents multiple species and a revision of the group would be desirable.

The new genus Hortophora in the orb-weaving spider family Araneidae Clerck, 1757 is established to include 13 species from the Australasian-Pacific region, with ten species known from Australia (five of which new to science): Hortophora biapicata (L. Koch, 1871), comb. nov. (type species) (= Araneus biapicatifera Strand, 1907, syn. nov.; = Epeira frosti Hogg, 1896, syn. nov.); H. cucullussp. nov.; H. lodicula (Keyserling, 1887), comb. nov. (= Epeira scutigerens Hogg, 1900, syn. nov.); H. megacanthasp. nov.; H. porongurupsp. nov.; H. tatianeaesp. nov.; H. transmarina (Keyserling, 1865), comb. nov.) (also known from Papua New Guinea); H. urbana (Keyserling, 1887), comb. nov.; H. walesiana (Karsch, 1878), comb. nov. (= Epeira rhombocephalaThorell 1881, syn. nov.; = Epeira lutulenta Keyserling, 1886, syn. nov.); and H. yesabahsp. nov. The following species of Hortophoragen. nov. are recognised from the Pacific region but not revised in detail due to a lack of material, specifically mature males: Hortophora capitalis (L. Koch, 1871), comb. nov. (removed from synonymy with H. transmarinacomb. nov.) from Fiji, New Caledonia and Vanuatu; H. flavicoma (Simon, 1880), comb. nov. from New Caledonia (incl. Loyalty Islands) and H. viridis (Keyserling, 1865), comb. nov. (removed from synonymy with H. transmarinacomb. nov.) from Samoa. Epeira thyridota Thorell, 1870 is here removed from synonymy with H. transmarinacomb. nov. and transferred to Backobourkia Framenau, Dupérré, Blackledge & Vink, 2010, B. thyridota (Thorell, 1870), comb. nov.Hortophoragen. nov. includes medium-sized to large, nocturnal orb-weaving spiders typically with subtriangular to ovoid abdomen bearing humeral humps. The tibiae of the second leg in males is usually enlarged with numerous strong spines and an apico-ventral megaspur carrying a large spine in some species. Male pedipalps generally have an elongated, transverse median apophysis ending in a bifid tip in most species, a sinuous to straight embolus and a bubble-shaped terminal apophysis. The female epigyne scape is highly elongated and does not have a terminal pocket. Genital mutilation, i.e. breaking off the epigyne scape during copulation, is common in some species. Hortophoragen. nov. include the most frequently collected nocturnal orb-weaving spiders in Australia.

We provide an updated catalogue of the type material of the lepidopteran superfamily Papilionoidea deposited in the Zoological Museum of Hamburg (ZMH). We report 414 specimens labelled as “types” belonging to nine species (all of valid names), 74 subspecies (44 valid names and 30 synonyms), 59 invalid infrasubspecific names under the ICZN code, and 23 specimens of 16 “in litteris” (= unavailable) names. Out of the 414 specimens labelled as “types”, 171 specimens are primary types (8 holotypes/lectotypes and 163 syntypes) and 80 are secondary types; 120 specimens are infrasubspecific and hence invalid and are considered as “original specimens”; and 43 specimens are treated here as “Non-type” specimens (topotype). We present a full bibliography of the original descriptions and illustrations for all of these taxa, aiming to provide a comprehensive taxonomic guide to this collection.

With 566 species, the neotropical genus Pristimantis is the most speciose vertebrate genus. As a result of its striking diversity, taxonomic reviews remain a challenge. Herein, we present an updated phylogeny of the Pristimantis lacrimosus group and describe a new species from Llanganates and Sangay National Parks. We also report, for the first time, the phylogenetic position of Pristimantis degener, P. eugeniae, P. katoptroides, and P. petersi. Based on our phylogeny, we add two species to the Pristimantis lacrimosus group. Through the integration of molecular and bioacoustic evidence, we describe a new species which was hidden under “Pristimantis petersi”. Pristimantis petersioidessp. nov. is most closely related to Pristimantis petersi and an undescribed species from Peru. It can be distinguished from P. petersi by its advertisement call and large genetic differences (uncorrected p-genetic distances 7.9% to 8.4% for gene 16S). Moreover, the new species and P. petersi are not sister species. We suggest assigning the new species to the Endangered Red List category because it has a small distribution range with deforestation as result of agriculture and other anthropogenic influences.

We describe a new species of frog from the eastern slopes of the Andes in central Peru. Pristimantis sirasp. nov. has a distinctive crossing mark on the iris and no tympanum. The new species is closely related to P. antisuyu Catenazzi & Lehr, 2018, P. cruciocularis Lehr, Lundberg, Aguilar & von May, 2006, and P. erythroinguinis Catenazzi & Lehr, 2018, but is easily differentiable by lacking colour blotches on groins. Pristimantis sirasp. nov. inhabits the mountain forests from 1550 to 2200 m a.s.l., inside a national reserve threatened by illegal mining.

Many regions of the world remain unexplored in terms of the tardigrade diversity, and the islands of the Indian Ocean are no exception. In this work, we report four species of the family Echiniscidae representing three genera from Mauritius, the second largest island in the Mascarene Archipelago. Two species belong in the genus Echiniscus: Echiniscus perarmatus Murray, 1907, a pantropical species, and one new species: Echiniscus insularissp. nov., one of the smallest members of the spinulosus group and the entire genus, being particularly interesting due to the presence of males and supernumerary teeth-like spicules along the margins of the dorsal plates. The new species most closely resembles Echiniscus tropicalis Binda & Pilato, 1995, for which we present extensive multipopulation data and greatly extend its distribution eastwards towards islands of Southeast Asia. Pseudechiniscus (Meridioniscus) mascarenensissp. nov. is a typical member of the subgenus with elongated (dactyloid) cephalic papillae and the pseudosegmental plate IV’ with reduced posterior projections in males. Finally, a Bryodelphax specimen is also recorded. The assemblage of both presumably endemic and widely distributed tardigrade species in Mauritius fits the recent emerging biogeographic patterns for this group of micrometazoans.

A new species of peacock spider, Maratus nemosp. nov., is described from the vicinities of Mount McIntyre and Nangwarry, South Australia. Unusual among members of its genus, the new species appears to inhabit ephemeral wetland complexes on marshy vegetation in shallow water. The discovery of Maratus nemosp. nov. is one of several recently described species attributed to the growing interest in amateur invertebrate macrophotography, with putative new species brought to attention of taxonomists through social media engagement.

A new species of the genus Cnemaspis Strauch, 1887 is described from the Rajgad fort in the northern Western Ghats of Maharashtra, India. The new species, belonging to the flaviventralis clade, is one of the smallest known Indian Cnemaspis and can be distinguished from other congeners by its genetic distinctiveness and few key morphological characters. The new species can be diagnosed from all other Indian congeners by its small body size (SVL < 27 mm), the absence of conical and spine-like tubercles on flank; heterogeneous dorsal pholidosis; presence of only femoral pores and no precloacal pores in males; weakly keeled scales on the ventral surface of neck, pectoral, abdominal region and limbs; granular scales on the tail with whorls of slightly enlarged, strongly keeled tubercles; and the absence of enlarged median subcaudal scales. The new species is currently known to inhabit the man-made historical structures from a single locality in Rajgad, Maharashtra, where it is presumed to be uncommon.
