A new intertidal dwarf bug, Corallocoris xishaensis Luo, Wang & Chen sp. nov., from Xisha Islands of South China Sea is described, and is the first record of the family Omaniidae Cobben, 1970 from China. The new species can be distinguished from its allied Austro-Oriental species C. marksae (Woodward, 1958) by the colour of its body and legs, and the genitalic structures of both sexes. Photographs of the habitus, head, thorax, abdomen, appendages and genitalic structures are provided, additional scanning electron micrographs of the body surface are presented as well. A key to all the species of Omaniidae and distributional maps based on the known records for all species of this family are provided.

[Labrador is a shorthand for Labrador Park, a nature reserve in SW Singapore]; (all in RMNH). Diagnosis: Body length of male (1.15–1.44), female (1.48–1.59). It can be distinguished from other species of Corallocoris by the following characteristics: the body is nearly black, the forewing has a distinct grey transverse fascia and grey apical margin (Fig. 7A–B, F). Habitat and biology. Corallocoris marksae was collected by searching volcanic rocks lying in the intertidal zone of a shallow, protected lagoon, which exposed 25 feet of beach at low tide and was covered by up to 2 feet of water at high tide (Kellen 1960). The motor behaviors of this species in the field were recorded by Kellen (1960) and he reared entire generations in the laboratory. Woodward (1958) recorded finding C. marksae mainly on the moist undersurface of the slabs of porous coral rock and on the sand and rock beneath when these rocks were exposed, together with Collembola, mites (Microtrombidium sp. and Eupodes sp.) and small beetles. Distribution: Australia (Great Barrier Reef); Malaysia (Malaya); New Caledonia (Îlot Croissant); Philippines (Badian, Luzon); Samoa (Tutuila Island); and Singapore (Sentosa Island) (Fig. 9A, Table 3)., Published as part of Luo, Jiu-Yang, Wang, Yan-Hui, Chen, Ping-Ping & Xie, Qiang, 2022, First record of the intertidal dwarf bug family Omaniidae from China, with description of a new species (Heteroptera: Leptopodomorpha), pp. 449-467 in Zootaxa 5195 (5) on page 462, DOI: 10.11646/zootaxa.5195.5.4, http://zenodo.org/record/7223747, {"references":["Woodward, T.

Thus, the number of known species of this genus is increased from eight to eighteen. Photographs of the habitus, forewing, abdomen and genitalic structures; drawings and scanning electron micrographs of male abdomen and genitalic structures are provided. A key to all the species currently recognized in the genus Kokeshia is presented, a distribution map and checklist for all known species is provided.

Basal portion of process with numerous small round pits and micro teeth. Right hemitergite VIII with long, stick shaped process projecting posteriad (Figs 11 E−F, 12E). GENITALIA. Pygophore slightly asymmetrical, dorsal surface with dense microtrichia, posterior area with relatively long setae. Parameres strongly asymmetrical, left paramere (Figs 11E, 12G‒H) with broadly blunt laminate extension directed dorsal near base, and with flattened and relatively broad distal projection, and slightly curved inward from middle of it; right paramere (Figs 11E, 12C‒D) with flattened, round and relatively slender distal projection. Apical portion of phallus (Figs 11D‒E, 12F) tubular, slender, forming less than one and a half coils outside of pygophore. Female Unknown. Distribution China: Yunnan (Fig. 32).

Diagnosis Kokeshia xiei can be recognized from all other species of Kokeshia by tergite VIII subdivided into two hemitergites, left hemitergite VIII with a long, thick and horizontally directed process, with numerous thick spiniform microtrichia at its ventral surface (Figs 23D‒E, G, 24A‒B).

A new genus and species of Schizopteridae, Cornonannus bui gen. et sp. nov. is described from Yunnan Province, China. The new genus is closest to Pachyplagia Gross, 1951, Ogeria, Distant 1913, and Kaimon Hill, 2004 in morphology, but it can be distinguished from these genera by the male having a frontal process, the absence of pronotal collar, the distinct venation of forewing, a tarsi formula of 3-3-3, and the middle area of abdominal tergites I to VII with small, round tubercles. Photographs of the male habitus, head, thorax, abdomen, appendages, and genitalic structures, as well as scanning electron micrographs of the male head, thorax, abdomen, and genitalic structures and drawings of male genitalia, are provided. Moreover, a key to all known Chinese schizopterid genera is presented.
