Report of a new genus Arboramima belonging to tribe Diestramimini, with a new species A. cattusis from Guangxi, China (Orthoptera: Rhaphidophoridae: Aemodogryllinae)

Abstract

A new genus (Arboramima Zong, Qin & He gen. nov.) with a new species (Arboramima cattusis Zong, Qin & He sp. nov.) is reported from Guangxi, China. The morphology of the new genus and species are provided. Samples of Aemodogryllinae species were selected for the reconstruction of phylogenetic tree based on mitochondrial COI fragment. The results supported the validation of the new genus. The type specimens are deposited in Museum of Biology, East China Normal University (ECNU).

Insights into the evolutionary history of Diestramimini cave crickets (Orthoptera, Rhaphidophoridae)

“…Gigantettix and Arboramima are sister groups, but they are quite different not only in appearance but also in male genitalia. Except for fore femora with inner spines and hind femora with both inner and outer spines on ventral surfaces, we have not found any other plesiomorphic state between them (Gorochov, 1998;Gorochov & Storozhenko, 2015;Zong et al, 2021). This may be due to the fact that too little is known about Arboramima.…”

“…trilobatus ). Specimens were identified using original descriptions (Dawwrueng et al, 2016; Gorochov, 1998; Gorochov & Storozhenko, 2015, 2019; Qin et al, 2019; Qin, Liu, & Li, 2016; Qin, Wang, et al, 2016; Storozhenko & Dawwrueng, 2014; Wang et al, 2019; Zhu et al, 2022; Zhu, Bian, & Shi, 2018; Zhu & Shi, 2018; Zhu, Wu, & Shi, 2018; Zong et al, 2021). Morphological images were acquired using a Leica DFC450 digital imaging system and specimen measurements followed Zhu and Shi (2018).…”

“…Four species belonging to two genera of the tribe Aemodogryllini were selected as outgroups (Diestrammena fengyangshanica, Tachycines asynamorus, T. meditationis, and T. trilobatus). Specimens were identified using original descriptions (Dawwrueng et al, 2016;Gorochov, 1998;Gorochov & Storozhenko, 2015Qin et al, 2019;Qin, Wang, et al, 2016;Storozhenko & Dawwrueng, 2014;Wang et al, 2019;Zhu et al, 2022;Zhu, Bian, & Shi, 2018;Zhu, Wu, & Shi, 2018;Zong et al, 2021). Morphological images were acquired using a Leica DFC450 digital imaging system and specimen measurements followed .…”

“…This may be due to the fact that too little is known about Arboramima. It is a monotypic genus, and the only species A. cattusis is nymph according to the original description and morphological photos (Zong et al, 2021). Therefore, we redescribe the species and provide the morphological photographs of adults (Figures 4 and 5a,b).…”

“…Diestramimini currently includes seven genera ( Adiestramima , Arboramima , Diestramima , Gigantettix , Megadiestramima , Mimadiestra and Tamdaotettix ), which can be distinguished by the shape of seventh abdominal tergite, paraproct and genitalia of male (Gorochov, 1998; Gorochov & Storozhenko, 1992, 2015, 2019; Storozhenko, 1990; Storozhenko & Dawwrueng, 2014; Zong et al, 2021). However, the classifications of genera are only based on morphological data.…”
