Background: Stingless bees is one group of eusocial insects living together in the hive. There are around 46 species of stingless bee in Indonesia with different morphological, morphometric and hive structure characteristics. This study aimed to describe the morphological, morphometric and beehives structure of Tetragonula laeviceps from Yogyakarta. Methods: Survey method is used by taking three sampling points of bamboo, house building and livestock crates in Bantul Regency. Sampling points determined by Purposive sampling method. An XSZ-107 BN binocular microscope analyzed samples of T. laeviceps with Optilab viewer and Image Raster software. Results: The results showed morphological characters of T. laeviceps are dominated shiny-black body, brownish-yellow antennas, klipeus on a head covered by fine silver hair, brownish-yellow mandible with two teeth, mesonotum in thorax covered by brownish to black hair, scutellum extended to propodeum, the ribbon of hair on the dorsal thorax is not very clear, and the hind tibia is rather hairy. Morphometric of T. laeviceps included body length between 3.44 - 3.76 mm, head width 1.55 - 1.70 mm, front wing length with tegula 3.76 - 4.37 mm, length of rear limbs tibia 1.37-1.57 mm, and the number of hamuli as many as 5. The beehive structure consisted of oval-shaped entrance formed funnel and varying internal hive in terms of the number of saplings, pollen cells, and honey cells. Conclusions: T. laeviceps have morphological, morphometric and hive structure characteristics that are different from other species and variated compared to similar species from other regions.

The subfamily Acastinae contains a diverse group of barnacles that are obligate symbionts of sponges and alcyonacean and antipatharian corals. Integrating morphological and genetic (COI) data to compare against known species, this paper reports on nine species of sponge-inhabiting barnacles of the subfamily Acastinae, including three undescribed species (Acasta caveata sp. nov., Euacasta acutaflava sp. nov., and E. excoriatrix sp. nov.) and three species previously not recorded in Australian waters (A. sandwichi, Pectinoacasta cancellorum, and P. sculpturata). The new species are distinguished from similar species by a suite of morphological characters as well as genetic distances. A lectotype for Pectinoacasta cancellorum is designated. Sponge hosts were identified for all specimens where possible and are represented by 19 species from eight families and five orders.

Two new species of the damselfly genus Euphaea Selys, 1840 (Odonata: Euphaeidae) are described from the Western Ghats of Satara District, Maharashtra, distinguished by their distinct morphology and coloration. E. thosegharensis Sadasivan & Bhakare sp. nov. is similar to E. cardinalis (Fraser, 1924), but is distinguished by the extensor and flexor surface of all femora black while all femora bright red in E. cardinalis; apical fourth of Hw black while apical half of Hw black in E. cardinalis; genae reddish-orange, black in E. cardinalis; a tuft of sparse stub black hair on either side of tergite of S9 while both S8 and S9 with tufts of long ventral hairs in E. cardinalis.  Male genital vesicle matt black, with distal border rounded angles, while vesicle black and hexagonal in shape with rounded angles in E. cardinalis and S9 twice the length of S10, while S9 and S10 of equal length in E. cardinalis. E. pseudodispar Sadasivan & Bhakare sp. nov., is very close to E. dispar (Rambur, 1842), but is differentiated easily by the absence of yellow patch on legs as in E. dispar; only apical fifth of Hw black; genae being yellowish-white, while black in E. dispar; male genital vesicle brownish-black & rhomboid-shaped and with no transverse rugosities while black with distal border rounded and with fine transverse rugosities in E. dispar; penis with single seta on each side while E. dispar has three pairs; sternite of S9 very prominently extending ventrally like a beak in comparison with E. dispar.  We have identified additional morphological characters useful in taxonomy of Euphaea of the Western Ghats for example, tufts of ventral hairs on terminal abdominal segments genital vesicle, penile structure of males and sternite of S9 in the males, and vulvar scales of females.  A taxonomic key to all known species of genus Euphaea of the Western Ghats is also provided.

Hypoxys is one of four subgenera of Edessa (Fabricius, 1787) together with Aceratodes (De Geer, 1773), Dorypleura (Lepeletier & Serville, 1825) and Edessa (Fabricius, 1787). This taxon has a very confusing taxonomy due to incorrect use of the names available, imprecise descriptions, and large number of very similar species. To illustrate the confusion, Hypoxys potentially includes a large number of species of Edessa, but actually contains only the type species, according to the most recent catalogue. The name E. quadridens Fabricius, 1803, type species of Hypoxys, was used for more than a century as a label to identify a large group of similar species. In this work we continue revising Edessa elevating Hypoxys to genus based on the following morphological characters: proximal part of costal margin black; evaporatorium with a deep notch on lateral margin; anterior arms of metasternal process acuminate; pygophore longer than wide and subrectangular or barrel-shaped in dorsal view; dorsal rim of pygophore well-projected, almost reaching posterolateral angles and finishing in a small lobe; and posterolateral angles of pygophore not developed. Hypoxys is being divided in four species groups to include 17 species transferred from Edessa. H. quadridens group comprises: Hypoxys quadridens (Fabricius, 1803) (type species), H. boerneri (Breddin, 1904) comb. nov., H. claricolor (Breddin, 1907) comb. nov., H. dolosus (Breddin, 1907) comb. nov., H. eburatulus (Breddin, 1907) comb. nov., H. necopinatus (Breddin, 1907) comb. nov., H. offuscatus (Breddin, 1907) comb. nov. and H. trabeculus (Breddin, 1907) comb. nov. H. triangularis group comprises: H. triangularis (Dallas, 1851) comb. nov. (type species), H. capito (Breddin, 1904) comb. nov. and H. subrastratus (Bergroth, 1891) comb. nov. H. oxyacanthus group comprises: H. oxyacanthus (Breddin, 1904) comb. nov. (type species), H. brachyacanthus (Breddin, 1904) comb. nov., H. infulatus (Breddin, 1904) comb. nov., H. leptacanthus (Breddin, 1904) comb. nov. and H. tragelaphus (Breddin, 1903) comb. nov. H. balteatus group comprises only H. balteatus (Walker, 1868) comb. nov. These groups of species will be useful to organize the new species of Hypoxys that will be described in upcoming papers. Descriptions, measurements, photos of genitalia of both sexes; photos in dorsal and ventral views of the species; and distribution maps are provided. Males of H. capito, H. claricolor, H. eburatulus, H. infulatus, and H. subrastratus are described for the first time. Female of H. necopinatus is described for the first time. Edessa jugalis is considered a junior synonym of H. quadridens; E. rimata a junior synonym of H. offuscatus; E. scabriventris and E. leprosula junior synonyms of H. triangularis; E. pachyacantha a junior synonym of H. tragelaphus; E. orba a junior synonym of E. oxyacanthus. A key to the species of Hypoxys is also provided.

The status of the common intertidal snapping shrimp, Alpheus inopinatus Holthuis & Gottlieb, 1958, is discussed based on newly collected material from Kuwait. Alpheus inopinatus was previously confused with morphologically very similar species in the Alpheus lobidens De Haan, 1849 species complex, formerly identified as A. crassimanus Heller, 1862 and herein tentatively referred to as A. cf. lobidens. The material herein examined strongly supports the validity of A. inopinatus based on several morphological characters, as well as differences in the colour pattern, compared to other members of the A. lobidens complex.

Gymnothorax melanosomatus new species, is described here on the basis of eight specimens collected from eastern coastal Taiwan at a depth 50–180 m. This new moray eel is distinguished from a closely similar species, G. prolatus, by a combination of the following characters: a uniformly black body when fresh (vs. brown), a relatively long preanal length 58.5 % of TL (vs. 48.9), shorter snout length 17.8 % of HL (vs. 20.0), interobital width 12.2 % of HL (vs. 14.3); more preanal vertebrae 105–109 (vs. 74–86) and total vertebrae 201–211 (vs. 174–190). The male and female are not different in body color and pattern, but the numbers of median intermaxillary teeth are different between the sexes, 0 in male and 2–3 in female.

The fern genus Pseudocyclosorus (Thelypteridaceae) from China and the Pan-Himalaya region is revised based on morphological study. Reduced basal pinnae, angles between costule and costae, and glands/hairs on abaxial surfaces/indusia are considered as the most diagnostic morphological characters for species delimitation. Genus Trigonospora was excluded from genus Pseudocyclosorus. This segregation is supported by multiple morphological features. Eight species were recognized here, namely Pseudocyclosorus tylodes, P. pseudofalcilobus, P. falcilobus, P. subochthodes, P. stramineus, P. ornatipes, P. esquirolii and P. canus. Twenty-one names were reduced as new synonyms. One name (P. duclouxii) was considered a dubious species. A key to these eight species, their descriptions, spore morphology and distribution map of each species are given.         Pseudocyclosorus stramineus was a long overlooked species, which has always been misidentified as other similar species, and was wrongly reduced as a synonym of P. duclouxii. Here based on morphology characters, the identity of P. stramineus as a species was reclaimed. A more detailed description with photographs and illustrations, and its whole distribution range are given here.

The systematic status of many Asian Draconine agamids has long been in dispute. Herein, four such species, Mictopholis austeniana, Japalura kaulbacki, Calotes kingdonwardi and Salea kakhienensis are examined on the basis of external morphological characters. The monotypic genus Mictopholis was compared to other Asian Draconine genera and found to be indistinguishable from Pseudocalotes, with which it is here considered a synonym. Japalura kaulbacki is compared to other members of the genus Japalura as well as other similar species. Based on external morphology it is found to be separable from Japalura and conspecific with Calotes kingdonwardi, under which it is considered a junior subjective synonym. Salea kakhienensis is redefined morphologically based on nontype material and shown to represent a close member of this group. C. kingdonwardi is most similar to Salea kakhienensis both of which share a complement of characters with M. austeniana. The generic placement of S. kakhienensis relative to Salea, both with strongly overlapping synapomorphic characters is briefly discussed with respect to biogeographical implications that strongly support the exclusion of this species from the genus. Mictopholis austeniana, Calotes kingdonwardi and Salea kakhienensis are redescribed in detail and transferred to Pseudocalotes. The inclusion of these three species provides a generic range extension of approximately 800 km north-west of the previously considered range. The nomen Oriocalotes discolor is considered a primary objective synonym of Pseudocalotes kakhienensis new comb. and the systematic status of Calotes kingdonwardi bapoensis is briefly discussed.
