Xizicus (Paraxizicus) Liu 2004
No full textXizicus (Paraxizicus) Liu, 2004 Xizicus (Paraxizicus) Liu & Yin, 2004: Insects from Mt. Shiwandashan Area of Guangxi, 100. Type species: Xizicus (Paraxizicus) anisocercus Liu, 2004 Body brown with blackish stripe, disc of vertex with 4 dark longitudinal bands, tegmina accompanied distinct dark spot, hind femora without dark latitudinal bands. Metazona no longer than prozona; wings fully developed; a forked process present on posterior margin of 10 th abdominal tergite, male cerci lobed or processed, a lump of membrane appears under lateral margin of 10 th abdominal tergite, subgenital plate specialized, apex spinous. Hind margin of female subgenital plate concave in middle. Diagnosis. Paraxizicus differs from the nominate subgenus in absence of hind femora stripes, membranous protrusions under male 10 th abdominal tergite and very specialized male subgenital plate. Discussion. The generic name Paraxizicus first mentioned by Liu in 2004 for the erection of a subgenus which subdivided from Xizicus, while Gorochov used the same in 2005 for the erection of a genus about a group of very different species, apparently Paraxizicus Gorochov, 2005 is a homonym of Xizicus (Paraxizcus) Liu, 2004. In fact Liu have already dealt with it in 2010.Published as part of Wang, Hanqiang, Jing, Jun, Liu, Xianwei & Li, Kai, 2014, Revision on genus Xizicus Gorochov (Orthoptera, Tettigoniidae, Meconematinae, Meconematini) with description of three new species form China, pp. 301-316 in Zootaxa 3861 (4) on page 305, DOI: 10.11646/zootaxa.3861.4.1, http://zenodo.org/record/493037

Bucculatrix nigerivalva Liu & Liu 2022, sp. n.
No full textBucculatrix nigerivalva sp. n. DZNJẇfl [Chinese name] Figures 3, 3a, 9–12 Diagnosis. The new species is closely related to B. crataega and the North American B. pomifoliella on the male genitalia. From B. crataega, the new species can be separated by: i) the strongly sclerotized and black distal part of the valva, ii) the furcated cornutus and iii) the almost semicircular vinculum; in B. crataega, the distal part of the valva is not as such strongly sclerotized and black (Fig. 7), the cornutus is composed of a series of micro spines (Fig. 8) and the vinculum is triangular on anterior margin (Fig. 7). From B. pomifoliella, the new species can be distinguished by: i) the cornutus composing of a series of micro spines and ii) the triangular vinculum (Braun 1963: 175, Fig. 228). Type material. Holotype, ♂, CHINA, Zhejiang province, Tianmu Mt., 30°20.27′N, 119°24.34′E, 700 m, 2018. vi.15, leg. Tengteng Liu, registration SDNU. Ent 000236 (genitalia and DNA barcode no. SDNU.LIU0156). Adult (Fig. 3). Forewing length 2.5 mm. Face and frons white, scale tuft on vertex white, mixed with orange in central. Labial palpus minute and white. Antenna with eye cap white, posterior half with brown scales dorsally, first flagellomere notched in male (Fig. 3a); flagellum blackish gray dorsally, 4 th to 7 th and 10 th to 13 th units counted from apex black dorsally. Legs yellowish white, black on outer surface of tibiae, with dense long yellow piliform scales on hind tibiae. Forewing ground color white, two golden costal streaks at basal 2/5 and 3/5, with scattered black scales near costa, outwards obliquely, jointed at apex of cell, the outer streak continue extending to tornus; a golden stripe along fold, below with a black dot at distal 2/5; a black dot above tornus; apical area golden; cilia grayish white, black distally around apex. Hind wing and cilia yellowish gray. Abdomen yellowish gray dorsally, yellowish white ventrally. Male genitalia (Figs 9–12). Socii developed, about 1/3 length of tegumen, with sparse long setae (Fig. 10). Tegumen sclerotized on lateral margin, straight on posterior margin. Valvae not fused with each other, heavily sclerotized towards apex, black on distal part; bifurcated distally, ventral branch curved inwards distinctively, rounded apically, dorsal branch slightly curved inwards, narrowed towards apex, bluntly pointed apically. Vinculum almost semicircular, more sclerotized and slightly protruded anteriorly. Phallus about 2.5 times as long as length of valva + vinculum, basal 1/3 arched, median 1/3 straight, then curved by 150°, distal 1/3 straight; basal 2/3 spindle-shaped together with membranous phallobase; cornutus a sclerotized spine, about 1/7 length of phallus, unequally bifurcated and curved distally. Scale-sac broad and rounded (Fig. 12). Distribution. China (Zhejiang). Only known from the type locality. Etymology. The specific name is derived from the Latin adjective “ niger ” and “ valva ”, indicating the black distal part of the valva in the male genitalia. Remarks. This species is associated with B. bechsteinella group in the sense of Baryshnikova (2008) and is closest to B. pomifoliella on the basis of morphological characters. However, the genetic uncorrected distance between B. nigerivalva and B. pomifoliella is the largest among the species group (Table 2).Published as part of Liu, Hongxia & Liu, Tengteng, 2022, Two new species of Bucculatrix Zeller from southeast China (Lepidoptera: Bucculatricidae), pp. 137-144 in Zootaxa 5100 (1) on pages 140-143, DOI: 10.11646/zootaxa.5100.1.8, http://zenodo.org/record/612788

TH-li in branching nerves and sensory clusters.
No full textTH-li staining of cilia clusters and nerves is green; DAPI staining of cell nuclei in the epithelium is blue. A, B: Thick branching TH-li nerves (arrows) approach the clusters of cilia (arrowheads) described earlier. Note individual TH-li neuronal cell bodies spread around nerve branches and lateral branchlets near cilia clusters’ bases. C, D: Several TH-li cell bodies (arrows) each produces a single cilia-like projection to the surface. These presumed receptor cells lie at the base of the cilia cluster (arrowhead). Neuropil-like areas are visible below clusters. An axon of a cell body of these TH-li cells at the left arrow in C branches laterally. Scale bars: A and B, 100 μm; C and D, 50 μm.</p

Hind tibia with 3 pairs of apical spurs. Male 10 th tergite extended into a pair of posteriormedian processes separated each other, apex enlarged into 2 hammer-like lobes, bend slightly downwards (Fig. 17a). Male cerci with basal half widened into broad lobe, apical half narrowed lobe and bend inward in right angle. Subgenital plate with roundly even posterior margin, styli short (Fig. 17 a–c).
