Zong, Jing-Song, Qin, Yan-Yan, Li, Kai & He, Zhu-Qing, 2021, Report of a new genus Arboramima belonging to tribe Diestramimini, with a new species A. cattusis from Guangxi, China (Orthoptera: Rhaphidophoridae Aemodogryllinae), Zootaxa 4981 (3), pp. 593-600 : 598

Arboramima cattusis Zong, Qin & He sp. nov.

Holotype: 1 male, CHINA, Guangxi, Guilin , Maoershan. (25.88°N – 110.49°E), alt. 1144m, 10-viii-2020, coll. Zong Jing-Song.

Paratypes: 4 males and 5 females, same data as holotype .

Description. Male. Body small to medium size, pubescence. Head with fastigium of vertex divided by two round tubercles, slightly separated at apex ( Fig. 5A–C ).

Legs long and slender. Fore femur about 2.2 times as long as the pronotum, femora unarmed on ventral surface, internal genicular lobe with 1 small spine, external genicular lobe with 1 long spine; tibiae with 2 external and 2 internal spines on ventral surface, apices with 1 pair of dorsal spines and 1 pair of ventral spines. Middle femora unarmed on ventral surface and with 1 movable spine on the internal and external knee lobe respectively; middle tibiae beneath with 2 internal and 2 external spines, apices with 1 pair of dorsal spines and 1 pair of ventral spines. Hind femora with 12–15 inner spines and 4–6 outer spines on ventral surface; tibiae with 22–28 inner spines and 26–29 outer spines on dorsal surface, subapices with 1 pair of dorsal spines, apices with 1 pair of dorsal spines and 1 pair of ventral spines ( Fig. 5G ).

Apex of paraproct blunt. Process of male 7th abdominal tergite rather short and narrowed into a trapezoid ( Fig. 5D–E ). Genitalia is membranous with 6 membranous lobes. The middle dorsal lobe is obviously longer than the middle ventral lobe, and its top is bifurcated and curved toward the back. The ventrolateral lobe is broad and nearly encompasses the whole dorsolateral lobe. The top of the ventrolateral lobe with bristles and gradually narrows and moves closer to the middle, almost the same length as the middle dorsal lobe ( Fig. 5F ).

Female. Subgenital plate nearly rectangle and with a truncated apex. Ovipositor sickle shaped, apex serrated, slightly longer than fore femur ( Fig. 5H–I ).

Coloration. Face with 4 longitudinal black stripes. Dorsal surface and ventral surface of dark green. Both sides of the abdominal tergite edge in yellow-green. All tibiae and femora with moss-like stripes. This unique color may be related to the environment where they live as their protective coloration ( Fig. 2 ; Fig. 3 ).

Measurements (in mm). Length of body ♂ 8.0–10.5, ♀ 7.7–13.0; length of pronotum ♂ 3.2–3.8, ♀ 3.3–3.9; length of fore femur ♂ 7.7–8.2, ♀ 7.8–8.6; length of hind femur ♂ 13.4–14.4, ♀ 13.7–15.7; length of hind tibiae ♂ 15.4–16.3, ♀ 16.2–16.4; length of hind basitarsi ♂ 3.6–4.2, ♀ 3.8–5.3; length of ovipositor 4.5–5.0.

Distribution. China (Guangxi).

Discussion. The new species is similar to Diestramima (Diestramima) arbora Wang, Zhu & Shi, 2019 , but differs in: smaller body size and more pigment attached to the body; protrusion of 7th abdominal tergite is short and not surpassing apex of paraproct, and the lateral lobes of male genitalia are more obtuse.

Etymology. The new species is named after its type locality Maoershan where means “cat mountain” in Chinese. The new species are also agile and smart as cats.
