BB28BA3B958B54458D7A490593DE77BB.taxon	etymology	Etymology. The scientific name of the new species is derived from Qu Yuan’s work “ Ai Ying ”: 惨郁郁而不通兮 [Can Yu Yu Er Bu Tong Xi], 蹇侘傺而含戚 [Jian Cha Chi Er Han Qi]. This couplet can be translated as: My mood is heavy with melancholy. I stand alone, filled with sorrow. It describes the poet’s sorrowful mood after the fall of the capital of Chu and the humiliation of King Chu by the people of Qin. Chachi (侘傺) describes a scene of standing alone in dejection in the poem. As a specific name, chachi implies that the new species is very rare, with only one sex having been discovered. The name is treated as a noun in apposition.	en	Wu, Zou-Yan, Chen, Jia-Heng, Shi, Hong-Liang (2025): Revision of the subgenus Morphohaptoderus Tschitschérine, 1898, in Hubei, China, with descriptions of ten new species (Coleoptera, Carabidae, Pterostichus).

27DCEAF8E3A25697A0064F8C6A9A0643.taxon	diagnosis	Diagnosis. Medium- to large-sized species for the subgenus (BL = 9.3 – 11.3 mm); elytral microsculpture linear in males, granular in females; antennomere 3 without accessory seta; pronotum relatively wide and slightly narrowed to base; pronotal basal foveae densely punctate; area between lateral channel and outer sulcus shallowly ridged, usually with a few fine punctures; lateral channels finely punctate along their full length; elytral interval 3 usually with two, sometimes three, setigerous pores, all adjacent to stria 2; fifth tarsomeres setose ventrally; male sternite VII asymmetrically depressed, with distinct oblique wrinkles. Median lobe of aedeagus with a sinuate ventral ridge; lamellar denticle large, nearly twice length of lamellar apex. Gonocoxite 2 of ovipositor crescent-shaped, dorsal margin ridged on apical half, outer margin with two or three ensiform setae of normal size. Comparison. The new species, P. quyuani sp. nov., is externally very similar to P. shennongjianus Facchini & Sciaky. These two species are sympatric and have often been confused with each other. Generally, they present the following differences in external characters: (1) In P. quyuani sp. nov., the region between the pronotal lateral channel and the outer sulcus of the basal fovea is typically less convex, forming a shallower ridge (Fig. 3 B). The outer surface of this ridge usually has a few fine punctures; in contrast, in P. shennongjianus this area is usually more convex, forming a more prominent ridge, and the surface of the ridge is usually impunctate (Fig. 3 C). (2) In P. quyuani sp. nov., the pronotal lateral channels are usually wider and finely punctate along their entire length. Conversely, in P. shennongjianus, the lateral channels are slightly narrower and at most punctate only behind the middle. (3) In P. quyuani sp. nov., elytral interval 3 usually has two setigerous pores, whereas, in P. shennongjianus, it usually has three or four pores. However, the external characters mentioned above can sometimes vary individually. In fact, it is extremely difficult to distinguish these two species (as well as the other two new species described herein, P. lisao sp. nov. and P. lingjun sp. nov.) based only on external features. Nevertheless, they can be reliably differentiated by the stable characteristics of male sternite VII, male genitalia, and gonocoxite 2 of the ovipositor. The male sternite VII of P. quyuani sp. nov. is shallowly depressed. There are shallow oblique wrinkles on the left side of this depression, and the apex of sternite is slightly truncated (Fig. 2 B). Conversely, the male sternite VII of P. shennongjianus has a much fainter depression, lacks wrinkles, and the apex of sternite is more rounded (Fig. 2 C). Compared to all other similar species from Hubei, the presence of wrinkles on the male sternite VII is a characteristic exclusive to P. quyuani sp. nov. (Fig. 2). Regarding the male genitalia, in P. quyuani sp. nov., the median lobe is very stout (Fig. 8 B). On its ventral surface, there is a sinuate short ridge that extends from the middle of the aedeagal base to the right margin and then terminates at the left margin (Fig. 8 C). In contrast, in P. shennongjianus, the median lobe is more slender (Fig. 10 B) and has a straight short ridge on the left margin of the ventral surface (Fig. 10 C). Furthermore, when considering the apical lamella of the aedeagus, in P. quyuani sp. nov., the lamellar denticle is very large, being nearly twice as long as the lamellar apex (Fig. 12 F – I). However, in P. shennongjianus, the lamellar denticle is smaller and approximately equal in length to the lamellar apex (Fig. 13 F – J). For the female ovipositor, in P. quyuani sp. nov., gonocoxite 2 shows the typical form of the subgenus: strongly curved, with a sharp apex, dorsal ridge absent on basal half, and ensiform setae large (Fig. 5 C). But in P. shennongjianus, gonocoxite 2 has a distinct form: nearly straight, with an obtuse apex, dorsal ridge almost reaching base of gonocoxite 2, and ensiform setae minute (Fig. 5 B). The newly described species P. quyuani also strongly resembles three other new species within the maximus group: P. lingjun sp. nov., P. lisao sp. nov., and P. wangshu sp. nov. Their comparison will be presented in the descriptions of those new species. When compared to species from other provinces, P. quyuani sp. nov. is most similar to P. lingshanus Sciaky & Wrase, 1997 from Shaanxi province, since both share characteristics such as the granular microsculpture in females, antennomeres 3 without accessory setae, and the pronotum not strongly constricted towards the base. However, P. lingshanus differs from the present new species in several ways: size generally smaller, male sternite VII not wrinkled, and lamellar denticle of the male genitalia much smaller, shorter than the lamellar apex when in lateral view. Regarding the depressed and wrinkled male sternite VII, the present species may also be related to P. maximus Tschitschérine, 1889, from Gansu, and P. dundai Sciaky, 1994, from Shaanxi. Nevertheless, compared to P. quyuani sp. nov., P. maximus is easily distinguishable by its elytral striae distinctly punctate and the male sternite VII more strongly wrinkled. P. dundai, on the other hand, differs in its pronotum more constricted towards base, male sternite VII depressed but not wrinkled, and the apex of the right paramere of male genitalia strongly elongated.	en	Wu, Zou-Yan, Chen, Jia-Heng, Shi, Hong-Liang (2025): Revision of the subgenus Morphohaptoderus Tschitschérine, 1898, in Hubei, China, with descriptions of ten new species (Coleoptera, Carabidae, Pterostichus).

The new species is named after Qu Yuan (屈原), a renowned poet and statesman in ancient China who lived in the State of Chu (centered around today’s Hubei Province) during the Warring States Period. His works, like “ Li Sao, ” shaped Chu Ci (also known as Songs of Chu, a significant genre in ancient Chinese literature). To commemorate Qu Yuan and promote the culture of Chu, the scientific names of all new species discovered in Hubei Province hereinafter are derived from Qu Yuan’s poems. The specific epithet is a genitive noun. Remarks. We examined one paratype of P. shennongjianus (Fig. 9 B, C).

E01713ABC2AA542B9045BD7B3D4CB1A1.taxon	etymology	Etymology. The scientific name of the new species is derived from Qu Yuan’s work “ Xiang Fu Ren ”: 时不可兮骤得 [Shi Bu Ke Xi Zhou De], 聊逍遥兮容与 [Liao Xiao Yao Xi Rong Yu]. This couplet can be translated as: The wonderful moments have passed, never to return. Let me roam at ease, with a leisurely air. Rongyu (容与) is a term used to depict a carefree scene in the poem. The name rongyu is proper for a Pterostichus species because these beetles are often seen running freely in the forest. The name is treated as a noun in apposition.	en	Wu, Zou-Yan, Chen, Jia-Heng, Shi, Hong-Liang (2025): Revision of the subgenus Morphohaptoderus Tschitschérine, 1898, in Hubei, China, with descriptions of ten new species (Coleoptera, Carabidae, Pterostichus).

This couplet can be translated as: Let Wangshu in front be the vanguard, and make Feilian closely follow behind. In “ Li Sao, ” Wangshu (望舒) is the name of the fairy who drives the chariot for the moon. It can also be referred to as the moon itself in other literature. The name wangshu is proper for a Pterostichus species because these beetles often run in the moonlight.

The scientific name of the new species is derived from Qu Yuan’s work “ Huai Sha ”: 玄文处幽兮 [Xuan Wen Chu You Xi], 蒙瞍谓之不章 [Meng Sou Wei Zhi Bu Zhang]. This couplet can be translated as: If delicate black carvings were placed in the darkness, they would remain unseen by the obtuse. This implies that Qu Yuan’s talent was not appreciated by others. Xuanzhang (玄章) refers to the delicate black carvings. The name xuanzhang is appropriate for a Pterostichus species, because these beetles are almost always black-colored with an elegant structure.
