Abstract 

A new genus Pulchricranae gen. nov. (type species: P. mirabilis sp. nov.) is described from grassland in Sakaerat Environmental Research Station in Nakhon Ratchasima Province, Thailand. This genus is similar to the genera Binaluacris Willemse and Bacuita Strand from Philippines by the presence of outer apical spines on hind tibiae; by tegmina abbreviated; by prosternal spine flattened; by lophi of epiphallus large, trapezium with rounded apex; and by basal and apical penis valves separated, without any sclerotized flexure. However, Pulchricranae gen. nov. differs from Binaluacris by fastigium of vertex with rounded margins; by tegmina shorter and slightly broader; by prosternal spine in male with broadly rounded apex, in female apex with rounded triangular notch in median part; by mesosternal lobe broader than long; by male cerci conical, much narrower near apical part. New genus also differed from Bacuita (known by females only) by female fastigium of vertex strongly short and broad; tegmen broader, with apex rounded; hind femur surpassing the apex of abdomen; subgenital plate with apex nearly truncate. The previously ungrouped genera of the subfamily Catantopinae, Binaluacris and Bacuita, are transferred to the tribe Cranaeini of the subfamily Hemiacridinae based on external morphology and male genitalia. The composition of the tribe Cranaeini is briefly discussed.

Abstract

A new genus of Spathosterninae, Tenasserimacris gen. nov. (type species: T. punctata sp. nov.), was discovered and described from a lower montane forest in Tenasserim Mountain Range of western Thailand, Khao Krajom in Ratchaburi Province. Clearly, this genus is similar to Beybienkoacris Storozhenko in the presence of parallel veinlets on the radial area of tegmina. However, this new genus differs from the latter in the temporal foveolae in both sexes, shape of ventral genicular lobe of hind femur in female, shape of furculae on 10th abdominal tergite in male, shape of valves of cingulum and apical valves of penis, shape of epiphallus, and shape of female subgenital plate. Additionally, tribe Tristrini is transferred from subfamily Tropidopolinae to Spathosterninae. Lastly, the composition and distribution of subfamily Spathosterninae are briefly discussed.

Abstract  

The genus Anacranae Miller includes five species distributed in Thailand, Malaysia and Vietnam. A new species, Anacranae maculata sp. nov., is described from northern Thailand. Hitherto unknown male of Anacranae vietnamensis Storozhenko is described and this species is recorded from Thailand for the first time. Anacranae beybienkoi Storozhenko known from northeastern Thailand is also widely distributed in western and northern Thailand. Anacranae nuda Miller and A. gorochovi Storozhenko are endemic to peninsular Malaysia and South Vietnam respectively. A key to species of Anacranae is also given.

Abstract

Four species of the genus Zhengitettix Liang, 1994 from Thailand are listed. A new distribution of Z. albitarsus Storozhenko, 2013 is reported from Ratchaburi Province in the Tenasserim Range with a coloration description of live specimens. Zhengitettix binduseni sp. nov. is described from Ratchaburi Province, Thailand. This new species is easily distinguished from other member in this genus by the larger body size, the fastigium of vertex between eyes distinctly narrower toward end, the slender and long spines of lower part of lateral lobe of pronotum which slightly upward in male, and almost straight in female, and the shaped of female subgenital plate with shallow transversal creases. The updated key to all species occurring in Thailand is provided here.

Abstract

The genus Ultragryllacris was revised. All its species and subspecies, including U. jiaranaisakuli sp. nov., U. chandra sp. nov. from Western Thailand and U. intermediata sp. nov. from Northern Thailand are here described and redescribed. They are known from Thailand and China. The new species differs from all the other representatives of this genus mainly in different body coloration, shape of projection of male 9th abdominal tergite and sclerotized area of female subgenital plate. The following taxonomical changes are also proposed: U. pulchra alboclypeata Gorochov et Dawwrueng, 2015, U. p. nan Ingrisch, 2018 and U. p. rubricapitis Bin et Bian, 2021 are raised to species status (U. alboclypeata stat. nov., U. nan stat. nov. and U. rubricapitis stat. nov.) due to some characteristic structures in both male and female; U. triangula Ingrisch, 2018 is downgraded to subspecies of U. alboclypeata (U. a. triangula stat. nov.). Previously unknown male of U. a. alboclypeata and female of U. nan are described. A key to all known species is given.

Type species Minirhaphidophora (Condylophora) ophioglossa sp. nov. 

Etymology The new subgeneric name originated from the Latinized Greek word “condylus” (tubercle) and the generic name “Rhaphidophora”. This is because the male of this subgenus has a pair of characteristic tubercles on its tenth abdominal tergite. 

Minirhaphidophora (Condylophora) ophioglossa Dawwrueng, Gorochov et Suwannapoom sp. nov.

Etymology The name of the new species originates from the Latinized Greek words “ophis” (snake) and “glossa” (tongue). This is because the apical part of the male epiproct in this species is more or less similar to a snake’s tongue in shape.

Abstract

A new species of dune cricket in the family Schizodactylidae, Schizodactylus salweenensis sp. nov. is described from Salween River, Mae Hong Son Province, northwestern Thailand based on both males and females. The Schizodactylidae is recorded for the first time in Thailand. The new species is most similar to Schizodactylus tuberculatus Ander, 1938 and Schizodactylus burmanus Uvarov, 1935 in the morphology of male subgenital plate, but mainly differs in the shape of subgenital plate apex, and the spurs of hind tibiae. The type series was collected from sand dunes along the river. This cricket reaches adulthood during the rainy season.
