Two new Hanguana species from Kalimantan, Indonesian Borneo, are described here. Hanguana karimatae from Karimata Island, West Kalimantan province, is characterised by a stout habit, prominently oblique yellow fruits with raised stigma and 1- or 2-seeded fruits. Hanguana nana from Central Kalimantan province is the smallest species in the genus with the stem entirely covered by leaves, deflexed barely branched infructescences with only a few fruits, each with a single bowl-shaped seed with a large and incurved appendage. These are the first descriptions of new Hanguana species from Kalimantan (Indonesian Borneo). Colour plates as well as notes on distribution, ecology, habitat and conservation status are provided.

Avicularia diversipes (C. L. Koch 1842) known previously only from its original description is redescribed along with Avicularia sooretama sp. nov. and Avicularia gamba sp. nov. The three species are endemic to Brazilian Atlantic rainforest. With other Avicularia species, they share a procurved anterior eye row, slender embolus and medially folded spermathecae, whereas they have unusual characters, such as a very long and spiraled embolus (A. diversipes) and spermathecae with multilobular apex (A. sooretama sp. nov.). Furthermore, the three species lack a tibial apophysis in males and share a distinctive color pattern ontogeny that is not known in any other Avicularia species. The conservation status of the three species is discussed, especially with respect to endemism, illegal trafficking and habitat destruction. The creation of protected areas in southern State of Bahia, Brazil, is recommended, as well as the inclusion of these species in IUCN and CITES lists. Appendices with figures and species information are presented to facilitate correct specimen identification by custom officers, in order to limit illegal traffic.

Abstract. Maknoi C, Saensouk S, Saensouk P, Rakarcha S, Thammarong W. 2021. Two new species of Curcuma L. (Zingiberaceae) from Thailand. Biodiversitas 22: 3910-3921. Curcuma aruna and C. pitukii, two new species from northern Thailand, are described, illustrated, and photographed. They are endemic to Sukhothai and Lampang Provinces, northern Thailand, and the morphological characteristics of two new species are compared with their closest species, C. flaviflora, C. eburnea, and C. pierreana. Two new species, C. aruna and C. pitukii are assignable to Curcuma subgenus Ecomata. C. aruna is recognized by leaves ovate with thin chartaceous, fertile bracts 6–12, it’s glabrous on nearly all parts of the plant, flowers yellow and labellum yellow with 2 darker yellow bands in the center. C. pitukii is recognized by bracts 20–40 with purplish white to purple, corolla lobes purplish white to pale purple, staminodes white, and labellum white with an embossed yellow path along the midrib from base to apex. A detailed description, distribution, ecology, etymology, preliminary conservation status, and photographs of two new species are provided. A key to 20 species of Curcuma subgenus Ecomata in Thailand is presented.

Two taxa of Amomum (Zingiberaceae), Amomum erythranthum and Amomum ampliflorum, from Putao, Kachin State of Northern Myanmar are described and illustrated as new to science. Amomum erythranthum is morphologically similar to A. subulatum and A. nimkeyense in having similar yellow flowers, but can be distinguished by its reddish floral tube, red anther connective, red and pubescent fruit. Amomum ampliflorum is similar to A. maximum, A. dealbatum and A. odontocarpum in white flower, but differs in its longer inflorescence and much larger flower. Two species, Amomum pauciflorum and Wurfbainia microcarpum are recorded for the flora of Myanmar for the first time. Data on ecology, phenology, distribution, conservation status, similarities to the related taxa, as well as colour photographs and line drawings of the type, and voucher specimens are provided for all reported taxa.

First Descriptions

Two new species of Geodiidae from the Emperor Seamounts, North Pacific Ocean are described and compared to congeners. Erylus imperator n. sp. differs from all other species of Erylus from the region in having large oxyasters, present in only one other species from which it differs in several other characters. Furthermore these oxyasters most often display the tendency to reduce the number of rays to a degree that they appear as triods, microxeas or even microtylostyles, depending on the number of retained rays. The second new species, Geodia arma n. sp. is a Geodia without triaenes, a group formerly described under the genus Geodinella. We compared G. arma n. sp. with all congeners lacking triaenes and determined that it is the only known species with a cortex of up to 6 mm in thickness and also the only species with oxeas up to 6 mm in length Which range from thin and sinuous to thick and straight. To our knowledge these are the first descriptions of sponge species from the Emperor Seamount region.

High Diversity

Brazil includes a very high diversity of bamboos, but this diversity is far from completely known. We increase the list of Brazilian woody bamboos by describing two new species of Chusquea, which belong to subgenus Rettbergia. Chusquea ciliatifolia sp. nov. differs from other species of this subgenus by its mottled culms, distinctly ciliate margins of the foliage leaf blades and pilose synflorescences; and C. mirabilis sp. nov. by the presence of branches with sericeous girdles. Both C. ciliatifolia and C. mirabilis occur exclusively in the Atlantic Forest, from the states of Bahia and Minas Gerais, known only from five and three populations, respectively. Comments on morphology, taxonomic relationships, ecological aspects, and conservation status of these new species are provided.

The ‘maccullochi species group’ of rainbowfishes are small and distinctly patterned freshwater fishes of streams and swamps, comprising around eight species. The species from which the group bears its name, Melanotaenia maccullochi Ogilby, 1915, has been thought to comprise three forms occurring in distinct geographic areas, and recent mitochondrial genetic data provides matching patterns of likely inter-specific divergence. Here we undertake a detailed investigation of the taxonomic status of M. maccullochi using a combined lines of evidence approach incorporating multiple nuclear genetic markers (55 allozyme loci), mitochondrial DNA sequence data (1141 bp cytochrome b) and morphology (examination of a suite of 38 morphometric and meristic characters). As all three datasets provide support for a three-way split, we accordingly describe two new species and redescribe M. maccullochi sensu stricto. McCulloch’s Rainbowfish M. maccullochi, a species with brown body stripes and red fins occurs in northeast Queensland and is redescribed based on 338 specimens, 13.1–53.0 mm SL. This species was one of the first rainbowfishes to become known in the aquarium hobby. A second form with darker stripes on a contrasting light white-grey body and with distinct sub-marginal black bands in the dorsal and anal fins, distributed across northern and eastern Cape York Peninsula, Torres Strait and southern central New Guinea, is described as Sahul Rainbowfish M. sahulensis sp. nov. based on 267 specimens, 13.4–48.4 mm SL. A diminutive and well geographically isolated form occurring below the escarpment of the Tabletop Range in Litchfield National Park, Northern Territory possessing a more prominent and purplish mid-lateral stripe, is described as the Little Rainbowfish Melanotaenia wilsoni sp. nov. based on 50 specimens, 19.3–33.3 mm SL. A combination of morphological characters is useful for separating the respective taxa with M. wilsoni sp. nov. the most distinctive, typically having fewer vertebrae, lateral scales, cheek scales, procurrent caudal rays and anal rays and proportionally a shorter maxilla and snout than either of the other two species. Useful characters for further separating M. sahulensis sp. nov. from M. maccullochi include slightly higher counts of vertebrae, lateral scales and anal rays and proportionally greater body depth, body width and pre-dorsal distance. Information on the known distribution, habitats and conservation status of the three species is summarised, with the Northern Territory species being a narrow-range endemic with specific environmental requirements.
