The first comprehensive phylogenetic analyses of the plant bug subfamily Deraeocorinae is presented. A total of 86 morphological characters and 3899 base pairs of mitochondrial (16S, COI) and nuclear (18S, 28S) sequences were analysed separately for each partition and combined datasets, using parsimony, maximum likelihood and Bayesian inference. The fossil species Amberderaeous gigophthalmusKim, Taszakowski & Jung, 2020 was analysed in the morphological and combined datasets in order to assess its systematic position. The phylogenetic results revealed that Deraeocorinae as presently constituted is not monophyletic, with the tribe Termatophylini nested separately to the other deraeocorine supraspecific lineages analysed. The remaining Deraeocorinae was found to be monophyletic as well as Clivinemini, Hyaliodini and Saturniomirini. Clivinemini + Saturniomirini is the sister group of the remaining Deraeocorinae. Deraeocorini, which is the most diverse tribe in the subfamily, was found to be non-monophyletic, with Surinamellini nested within it. Based on the results, we proposed that the clade including the questionably placed taxa and a temporarily placed fossil taxon is synonymized from Surinamellini to Deraeocorini, and that Surinamellini is treated as paraphyletic. The nominate genus Deraeocoris s.l. was found to be non-monophyletic. Termatophylini was provisionally retained within Deraeocorinae, pending broader taxon sampling of Deraeocorinae and other mirid subfamilies.

We summarize the knowledge on Australian Cylapinae and review all recorded genera. Two species, Lygaeoscytus carnarvon sp. nov. and Phyllofulvius tarkine sp. nov., are described as new to science. Schizopteromiris Schuh, S. lordhowensis Schuh, S. montheithi Schuh, S. queenslandensis Schuh, Howefulvius Schmitz & Stys, H. elytratus Schmitz & Stys, Lygaeoscytus Reuter, Lygaeoscytus cimicoides Reuter, Phyllofulvius Carvalho and Phyllofulvius australianus Carvalho are redescribed. Rhinomiriella Gorczyca is synonymised with Ceratofulvius Reuter. Cylapofulvius listeri Izzard is transferred to Micanitropis Namyatova & Cassis. Peritropisca Carvalho & Lorenzato is recorded from Australia for the first time. The identification key to Australian genera, images of some holotypes, diagnoses, digital habitus images, scanning electron micrographs, illustration of genitalia and distribution maps are provided for new species and some other taxa. Considering the results of this work, 23 genera and 48 species of Cylapinae are currently recorded from Australia. The distribution and collection techniques are discussed.

Known only from the two localities in Cape Range National Park, Western Australia (fig 5). Hosts. Initial series collected from flowering Ipomoea yardiensis A.S. George shrubs (fig 6A). This species is narrowly distributed in the Exmouth local government area of northwest Western Australia, where it is commonly found. It is a perennial shrub of about 1.5 metres, with broad grey-green leaves and purple tubular flowers. Additional specimens were subsequently collected from the dried base of Triodia epactia S.W.L. Jacobs (fig 6B). This tussock-forming perennial is a “soft spinifex and is coated with sticky resin on its green surfaces. DNA sequence data. Nucleotide data amplified from the holotype male WAME106179 and paratype female WAME106180 for the mitochondrial gene regions COI (accession numbers OL457614 and OL 457615) and 16S (OL 462857 and OL 462858) are available on GenBank. Remarks. Turrana ejuncida sp. nov. and T. abnormis are similar in morphology, with the new species differing by the longer labial segment which reaches beyond the midpoint of the mesosternum (cf. restricted to procoxae in the type species), the sparser distribution of scalelike setae, the absence of a keeled scutellum. Turrana abnormis is known from tropical Australia, with collection records from northern parts of Queensland, the Northern Territory, and the Kimberley region of Western Australia (Cassis & Gross 2002) (fig 5). Presently T. ejuncida sp. nov. appears to have a more southwestern distribution, known only from the Gascoyne Region of Western Australia (fig 5). The erection of T. ejuncida sp. nov. as a new species is based on comparison to the original description of T. abnormis by Distant (1911), observation of the syntype photograph of the species available online through the Coreoidea Species File (CoreoideaSF Team 2021), and observation of a single female specimen collected during a Bush Blitz survey in the Kimberley region of Western Australia (Palmer Creek, 15.956°S 127.57627°E, 5 June 2014, N.J. Tatarnic & J. Karras, WAM), and an additional six specimens from nearby Kununurra, as well as the diagnostic characters, including genital illustrations, given by Brailovsky (2007).

Head (figs 1; 2A���C): subrectangular in dorsal view, longer than wide; dorsally mostly flat; frons with short midline sulcus; clypeus vertical, barely visible from above, without apical spine; mandibular plates (= jugae) large, apically rounded, projecting well beyond clypeus, separated at midline; maxillary plates small and tumescent, projecting anteriorly just beyond clypeus; ocelli small and flattened with a diagonal slit-like scar; bucculae small with margins arcuate. Eyes (figs 1A���D; 2A���D): small, suboval, positioned between midpoint of head or caudal to the midpoint. Antennae (figs 1A���D; 2C): greatly enlarged, inserted at front of head; subequal to length of head to apex of scutellum; AI���AIII cylindrical, thickened, and subequal in length; AIV clavate and shortest antennomere Labium (figs 1B, D; 2A, C): extending between posterior margin of prosternum or beyond midpoint of mesosternum. Thorax (figs 1A���D; 2A���B, D���E): pronotum nearly flat, with lateral margins weakly divergent caudally; anterolateral angles acute; humeral angles rounded; callosite region medially divided by pair of longitudinal sulci; pronotal disc with pair of minor swellings; posterior margin rounded with medial concavity; scutellum short, flat, with or without midline weakly raised or keel-like; pro- and mesosternum with conspicuous midline furrow to receive labium. Hemelytra (fig 1A, C): brachypterous, narrower than abdomen, contiguous with the medial margin of the laterotergites, reaching abdominal terga V���VI; clavus short, commissure a little longer than scutellum; corium with raised veins and closed cells; membrane with anastomosing venation.

Male genitalia (fig 2A���C): pygophore cupshaped, caudal margin projecting, partly visible from above, genital opening dorsal in orientation. Female genitalia (fig 4A���C): elongate, tubelike. Distribution. Two species distributed in Australian Monsoonal Tropics (fig. 5). Remarks. Brailovsky (2007) hypothesised that Turrana is allied to Postleniatus, because of the elongate head (longer than wide), absence of a postocular tubercle, the concave posterior margin of the pronotum, the short legs, the unarmed femora, the flat ocelli and the deeply punctate hemelytra. Brailovsky (2007) distinguished Turrana from Postleniatus by AIII being longer than AII, the smaller eyes, the shorter labium (not reaching beyond the prosternum), the labial groove not extending to the metasternum, and the elongate female terminalia. Brailovsky (2007) also differentiated the other Australian acanthocorine genus Pomponatius from Turrana by its transverse head, ventrally armed femora, and the presence of a postocular tubercle, as well as it having shallower punctures. We have observed armed femora in Pomponatius, which were not illustrated in the habitus images of Brailovsky (2007). Turrana ejuncida sp. nov. is mostly consistent with the diagnostic characters given by Brailovsky (2007) but differs by the longer labium, which reaches near the posterior margin of the mesosternum: this character state separates it from T. abnormis and is more like Postleniatus glycosmisus. Nonetheless, T. ejuncida sp. nov. is undoubtedly congeneric with T. abnormis, and the revised diagnosis of Turrana herein excludes the very short labium character as given in Brailovsky (2007). Both Turrana species also have a clavate AIV as opposed to the fusiform shape found in Postleniatus glycosmisus., Published as part of Tatarnic, Nikolai J. & Cassis, Gerasimos, 2022, Turrana ejuncida, a new species of Acanthocorini (Hemiptera: Heteroptera: Coreidae) from Cape Range, Western Australia, with discussion of its systematic position and host plant associations, pp. 85-96 in Zootaxa 5092 (1) on page 87, DOI: 10.11646/zootaxa.5092.1.4, http://zenodo.org/record/5869600, {"references":["Distant, W.
