Two New Species

Two new species of the ant genus Myrmecina Curtis, 1829 are described and illustrated based on the worker and queen castes collected in Sumatra, Indonesia under the names M. andalas sp. nov. and M. nitidiuscula sp. nov. Each species displays unique morphological characteristics. Myrmecina andalas sp. nov. is characterized by a combination of the following characteristics: head dorsally sculptured, with the ventrolateral area smooth and shiny; propodeal spine short, triangular, pointing dorsad and with a broad base; propodeal declivity vertical, with the posterodorsal angle almost 90°. Myrmecina nitidiuscula sp. nov. is characterized by a combination of the following characteristics: head dorsum largely smooth and shiny; propodeal spine triangular and pointing posteriad, with a very broad base. Updated key to Myrmecina species of Sumatra is given.

Summary Two new Neomisticius species, typologically and phylogenetically close to each other, are described and illustrated from dead Quercus trees and an ambrosia beetle, Platypus quercivorus. The two species share some stylet morphological characteristics, namely, they both possess a long conus occupying more than half of the total stylet length, a long crustaformeria composed of more than 160 cells (eight rows of more than 20 cells each), and a short and broad female tail with a digitate tip. They are distinguished from each other by N. variabilis n. sp. having a wide, spindle-shaped male bursa with a blunt terminus and N. platypi n. sp. having an oval bursa with a rounded terminus. In addition, the males and females of both species have three large rectal glands and the posterior end of the male testis (distal end of the vas deferens) bears three cells that seemingly function as a valve between the vas deferens and the cloacal tube. These characteristics have not been reported in other tylenchids. Currently, the genus contains only three species: the two new species and N. rhizomorphoides, which has a normal stylet with a short conus, a short crustaformeria, and lacks rectal glands and valve cells in the vas deferens. Therefore, the two new species are readily distinguished from N. rhizomorphoides and, based on the previous definition, may even represent a new genus. However, considering their phylogenetic closeness and biological similarities (e.g., association with ambrosia beetles), the generic definition of Neomisticius was emended to include these new species.

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.

Shoot Blight

Peach shoot blight (PSB), which kills shoots, newly sprouted leaf buds and peach fruits, has gradually increased over the last ten years and has resulted in 30-50% of the total production loss of the peach industry in China. Phomopsis amygdali has been identified as the common causal agent of this disease. In this study, two new species, Phomopsis liquidambaris (strain JW18-2) and Diaporthe eres (strain JH18-2), were also pathogens causing PSB, as determined through molecular phylogenetic analysis based on the sequences of the internal transcribed spacer region (ITS), translation elongation factor 1-α (EF1-α) and beta-tubulin (TUB), and colony and conidial morphological characteristics. Biological phenotypic analysis showed that the colony growth rate of strain JW18-2 was faster than that of strains JH18-2 and ZN32 (one of the P. amygdali strains that we previously found and identified). All three strains produced α-conidia; however, JW18-2 could not produce β-conidia on alfalfa decoction and Czapek media, and the β-conidia produced by strain JH18-2 were shorter in length and thicker in width than those produced by strain ZN32. Pathogenicity tests showed that JW18-2 presented the strongest pathogenicity for peach fruits and twigs and was followed by strains JH18-2 and ZN32. The results shed light on the etiology of PSB and provide a warning that P. liquidambaris or D. eres might develop into dominant species after a few years, while also potentially benefitting the development of effective disease control management strategies.

During survey on rock-inhabiting fungi from karst habitats in Guizhou, China, two new species in Cyphellophora were discovered and identified. Phylogenetic analysis based on combined sequences of the nuclear large subunit (nucLSU) and internal transcribed spacer (ITS) region of ribosomal DNA revealed that the tested isolates, clustered into two clades that well affiliated in the genus of Cyphellophora. Morphological characteristics were also supported the estabolishment of the new species. Herewith Cyphellophora botryose sp. nov. and Cyphellophora guizhouensis sp. nov. were described and their differences from closely related species were discussed.

Morphological Differences

Two new species of Phoxokalliapseudes from the southwestern and southern coasts of Korea are described. Phoxokalliapseudes aculeatus n. sp. is distinguished by the two robust spiniform setae on the ventral margin of the cheliped basis, pereonites 2–6 each with a hyposphaenium and small spinules, and the setiferous lobe on the mandibles with different numbers of serrated spiniform setae in the female and male (five and six, respectively). Phoxokalliapseudes cinctus n. sp. can be distinguished by the propodus of the male cheliped with the largest length to width ratio (2.5: 1) of the genus, and the fixed finger with small denticles on the cutting edge and near the insertion of the dactylus. The female has the largest dactylus to propodus length ratio of pereopod 6 in the genus. Only four species of Phoxokalliapseudes have been described or redescribed previously, of which some exhibit morphological differences with the type specimens, possibly indicating additional new species. To minimize identification difficulties caused by morphometric variations in developmental stages, the morphological characteristics of the new species are described in detail for a fixed size range and compared to different-sized individuals. Additionally, a comprehensive comparison of the new Phoxokalliapseudes species with the other known species is provided and discussed.

First Time

The diversity of Cranichis in Bolivia is evaluated. An updated key for identifying species is provided. Morphological characteristics of 15 species of Bolivian Cranichis are presented together with illustrations of their floral segments. The occurrence of C. diphylla, C. lehmannii, and C. muscosa in this country was not confirmed. In our opinion the previously published Bolivian record for C. polyantha is doubtful. For the first time, C. badia and C. longipetiolata are reported in this country. Two new species of Cranichis are described.
