Abstract. Saensouk S, Boonma T, Thomudtha A, Thomudtha P, Saensouk P. 2021. Short Communication: Curcuma wanenlueanga (Zingiberaceae), a new species of subgenus Curcuma from Thailand. Biodiversitas 22: 2988-2994. Curcuma wanenlueanga Saensouk, Thomudtha & Boonma, a new species of Curcuma subgenus Curcuma (Zingiberaceae) from Thailand was described with detailed illustrations, and photographs. The dominant morphological description is terminal inflorescence, leaf adaxially green with reddish-purple along the midrib, leaf-sheath with reddish-brown tinge. Moreover, the color and smell rhizome of C. wanenlueanga has yellow with a darker core internally. It is distributed in Mae Hong Son Province, Northern Thailand, and cultivated throughout the country, i.e. Nakhon Nayok, Maha Sarakham, Chiang Mai, Tak, Chantaburi, Suratthani, and Kanchanaburi Provinces. It is used as Thai traditional medicinal. It grows in in sandy loam soil and well-drained in the mixed-deciduous forest, at elevation 700-900 m asl. It is accompanied by a revised key to 26 species of Curcuma subgenus Curcuma from Thailand.

Molecular Description

A new species of Teleopsis (Diptera, Diopsidae) from Chiang Mai, Thailand is described and illustrated. Teleopsis thaii Földvári & Carr is shown to be a member of a species group, termed the dalmanni species group, along with three previously described species. Presented here are a morphological description of T. thaii and an allometric comparison of the species with other members of the Teleopsis genus. We also present multi-gene phylogenetic analyses to highlight the possible position of T. thaii within the dalmanni species group.

Petronymphe rara is described and illustrated as a new species, endemic to the state of Oaxaca, Mexico, which develops in gypsum soils in the tropical deciduous forest of the Oaxacan Mixteca Alta. This species differs from P. decora, the latter distributed in the state of Guerrero, Mexico, in leaf shape, floral tube size and color and stamen size. We also report the rediscovery of P. decora, a species not collected since 1949 and described in 1951 by Harold E. Moore, including a complete morphological description. In addition, we present an expanded genus description to accommodate the new species.

Pariana caxiuanensis (Poaceae) is described and illustrated as a new species from the Brazilian Amazon. The new species is characterized by having the leaves clustered at the apex of the leafy culm, fimbriae few to absent, dimorphic flowering culms, large ligules (2.5–4 mm long), and pubescent to hirsute synflorescences.

Phytoseiid mites have been intensively surveyed in Taiwan during the past decades because of their potential as biological control agent. Despite the fact, many regions of Taiwan remain under-explored especially in mountain areas and neighboring islands. Typhlodromus (Anthoseius) crossostephium sp. nov. was collected from Crossostephium chinense (L.) Makino (Asteraceae) on rocky shore habitat during a survey on Lanyu Island. In this paper, presence of a phytoseiid mite on rocky shores is reported for the first time. A detailed morphological description of the new species and a key to the Taiwanese species of subgenus Anthoseius are provided.

A New Species

A new species, Rhaphidosoma paganicumsp. nov. (Heteroptera: Reduviidae: Harpactorinae: Rhaphidosomatini), is described from the Dry Zone of Myanmar. It is the fifth species of Rhaphidosoma Amyot et Serville, 1843, known from the Oriental Region, and the first record of the genus for Myanmar and Indochina. The structure of the external and internal terminalia of the male and female is described and illustrated in detail. The completely inflated endosoma is described for the first time in reduviids. The complex structure of the ductus seminis is shown; it terminates with a voluminous seminal chamber which opens with a wide secondary gonopore and may be a place where spermatophores are formed. The new species is compared with all congeners from the Oriental Region and Western Asia. It is characterised by the absence of distinct tubercles on the abdominal tergites of the male, the presence only two long tubercles and small rounded ones on the abdominal tergites VII and VI, respectively, in the female, the presence of short fore wing vestiges which are completely hidden under longer fore wing vestiges, and other characters. In addition to the morphological description, an account is given of the male karyotype and the structure of testes of Rh. paganicumsp. nov. and another species of Harpactorinae, Polididus armatissimus Stål, 1859 (tribe Harpactorini). It was found that Rh. paganicumsp. nov. has a karyotype comprising 12 pairs of autosomes and a multiple sex chromosome system (2n♂=24A+X1X2X3Y), whereas P. armatissimus has a karyotype comprising five pairs of autosomes and a simple sex chromosome system (2n♂=10A+XY). The males of these species were found to have seven and nine follicles per testis, respectively. FISH mapping of 18S ribosomal DNA (major rDNA) revealed hybridisation signals on two of the four sex chromosomes (Y and one of the Xs) in Rh. paganicumsp. nov. and on the largest pair of autosomes in P. armatissimus. The presence of the canonical “insect” (TTAGG)n telomeric repeat was detected in the chromosomes of both species. This is the first application of FISH in the tribe Raphidosomatini and in the genus Polididus Stål, 1858.
