Abstract:

Structural features of the eggs of a basal phasmatodean, Timema monikensis Vickery & Sandoval, 1998 (Timematidae) were examined. The eggs of this species are soft and deposited coated with soil and/or other extraneous particles. The chorion, which is transparent and weakly sclerotized, is composed of an endochorion and an exochorion. The non-inclined operculum is located at the anterior pole of the egg. The chorion in the marginal region of the operculum is thinned to form an opercular collar together with the chorion of the egg body. An inverted triangular micropylar plate is on the ventral side of the egg attached to the opercular collar. The micropylar plate is without external differentiations but is specialized inside the chorion. A single micropyle, with a simple funnel-shaped chorionic opening, occurs on either side of the micropylar plate. The posterior mound, located at the posterior pole, is a thickened chorion rich in fine vertical striations, and the serosal cuticle beneath is thickened and highly specialized. The eggs of Timematidae were characterized and compared with those of Euphasmatodea and Embioptera. A phylogenetic discussion is presented, strongly supporting the assemblage of Timematodea, Euphasmatodea and Embioptera as monophyletic.

Abstract:

Background: Lonchodidae is the largest family within the order Phasmatodea, and although many studies have been conducted on this family, the monophyly of the family has not been established. Methods: Eight mitogenomes from Lonchodidae, including the first complete mitogenomes of four genera, were sequenced and annotated to explore their features and phylogenetic relationships. Results: The total length ranged from 15,942–18,021 bp, and the mitogenome consisted of 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes, and a control region (CR). atp8 had the highest A + T content in Lonchodidae, except for Neohirasea stephanus and Asceles clavatus, in which the highest A + T contents were detected in nad6. The phylogenetic trees were reconstructed via Bayesian inference (BI) and maximum likelihood (ML) based on the PCG123 and PCG12 datasets. As the phylogenetic trees show, Necrosciinae is recognized as monophyletic, but the monophyly of Lonchodinae has not been supported. Gene deletion and rearrangement have occurred mainly in Lonchodidae and Aschiphasmatidae. The most common reason for gene rearrangements was tandem duplication random loss (TDRL), but trnI of Stheneboea repudiosa inverted into the CR. In addition, genes within the same family or genus share related sequences and conserved gene blocks. Conclusions: we expanded the mitochondrial genomic data for this family, thereby establishing a foundational dataset for future studies.

Abstract:

Extant stick and leaf insects commonly imitate twigs or leaves, with lateral lamellae used to enhance crypsis or achieve mimicry for protection. However, the origin and early evolution of such lateral expansions among Phasmatodea are unknown, because all known Mesozoic phasmatodeans hitherto lack preserved evidence of such structures. We report here the first Mesozoic stick insect, Elasmophasma stictum gen. et sp. nov., with well-preserved, thin, lateral lamellae on the thoracic pleura, the terga of abdominal segments I–X and the ventrolateral margins of all femora. This new species, from the mid-Cretaceous amber of northern Myanmar, has a clear, stick-like body and is assigned to Euphasmatodea. The abdominal structures of E. stictum exhibit traces of multiple expansions of the terga, suggesting that such structure might have been an early development of body expansions used to improve crypsis for stick or leaf insects when they sprawled on twigs or leaves.

Abstract:

AbstractStem-group Phasmatodea, known as the Susumanioidea, are previously established from the Jurassic through the Paleocene. Here, we extend this record to the early Eocene with five new fossils: two forewings from the Klondike Mountain Formation exposures at Republic, Washington, United States of America, and three partially complete specimens from the McAbee locality in southern British Columbia, Canada. We assign both of the Republic specimens to the new genus and species Eoprephasma hichensinew genus, new species. Two of the McAbee fossils appear to represent two further new species, which we refer to as Susumanioidea species A and B for lack of clearly preserved diagnostic species-level character states. The third might belong to one of these two species, but this is unclear. In all three, the mesothorax and metathorax are not notably extended, the forewings are not shortened, the foreleg femur is straight, and species A possesses an extended, external ovipositor with an operculum (unknown in the other specimens). These conditions are rare and never found in combination in Euphasmatodea. All other stem-group Phasmatodea younger than the Early Cretaceous of China are only known from isolated wings.

Abstract:

Two species of stick insect with a distinctive morphology, Candovia evoneobertii (Zompro & Adis, 2001) and Echetlus fulgens Zompro, 2004, were considered to be native to Australia and introduced into Brazil. However, Heteronemia dubia (Caudell, 1904) and Heteronemia fragilis (Brunner von Wattenwyl, 1907), both described more than a hundred years ago from South America, exhibit striking similarities with the two purportedly introduced species and are found to be conspecific with C. evoneobertii. Careful analysis of the literature and specimens revealed that these species belong to the Neotropical tribe Diapheromerini (Diapheromeridae) and represent a new genus, Arumatia Ghirotto gen. nov. We therefore propose Arumatia fulgens (Zompro, 2004) gen. et comb. nov. and Arumatia dubia (Caudell, 1904) gen. et comb. nov. We further redescribe A. dubia (Caudell, 1904) gen. et comb. nov. based on several specimens and synonymize Heteronemia fragilis syn. nov. and Candovia evoneobertii syn. nov. under it. Additionally, five new Brazilian species are described: Arumatia diamante Ghirotto gen. et sp. nov. from Abaíra, Bahia; Arumatia aramatia Ghirotto gen. et sp. nov. from Porto Nacional, Tocantins; Arumatia motenata Ghirotto gen. et sp. nov. from Serra do Cipó, Minas Gerais; Arumatia crassicercata Ghirotto, Crispino & Engelking gen. et sp. nov. from Alto Paraíso de Goiás, Goiás; and Arumatia anyami Ghirotto, Crispino & Neves gen. et sp. nov. from Costa Marques, Rondônia. Species of Arumatia gen. nov. occur mostly in the Cerrado domain, and represent the first Diapheromeridae recorded in this area. Most species are known exclusively from females with only A. aramatia gen. et sp. nov. and A. motenata gen. et sp. nov. known from both sexes. Adult and egg morphology are described and illustrated in detail for all species, as well as the nymph stages for A. dubia. Biological observations are presented, including parthenogeny in A. dubia and one of the few detailed accounts of sexual behaviour in Euphasmatodea (for A. motenata gen. et sp. nov.). Finally, a species of Diapheromerini described in error from Brazil, Diapheromera armata Piza, 1973, is synonymized under the North American Megaphasma denticrus (Stål, 1875) (syn. nov.).

Abstract:

With the recent advance in molecular phylogenetics focused on the leaf insects (Phasmatodea, Phylliidae), gaps in knowledge are beginning to be filled. Yet, shortcomings are also being highlighted, for instance, the unveiling of numerous undescribed phylliid species. Here, some of these taxa are described, including Phyllium iyadaon sp. nov. from Mindoro Island, Philippines; Phyllium samarense sp. nov. from Samar Island, Philippines; Phyllium ortizi sp. nov. from Mindanao Island, Philippines; Pulchriphyllium heracles sp. nov. from Vietnam; Pulchriphyllium delislei sp. nov. from South Kalimantan, Indonesia; and Pulchriphyllium bhaskarai sp. nov. from Java, Indonesia. Several additional specimens of these species together with a seventh species described herein, Pulchriphyllium anangu sp. nov. from southwestern India, were incorporated into a newly constructed phylogenetic tree. Additionally, two taxa that were originally described as species, but in recent decades have been treated as subspecies, are elevated back to species status to reflect their unique morphology and geographic isolation, creating the following new combinations: Pulchriphyllium scythe (Gray, 1843) stat. rev., comb. nov. from Bangladesh and northeastern India, and Pulchriphyllium crurifolium (Audinet-Serville, 1838) stat. rev., comb. nov. from the Seychelles islands. Lectotype specimens are also designated for Pulchriphyllium scythe (Gray, 1843) stat. rev., comb. nov. and Pulchriphyllium crurifolium (Audinet-Serville, 1838) stat. rev., comb. nov. from original type material.

Abstract:

With the first large-scale Phylliidae molecular phylogeny recently published adding a great deal of clarity to phylliid diversity, several of the rarer species which could not be included were methodically and morphologically reviewed. This review resulted in identification of numerous substantial morphological features that suggest there are Melanesian clades that create polyphyletic groups within the phylliids which should instead be taxonomically recognized as unique. These rarer Melanesia species have historically been considered to be southern representatives of the Pulchriphyllium Griffini, 1898 sensu lato. However, there are notable morphological differences between the Pulchriphyllium sensu stricto and the "schultzei" group. Therefore, two new genera are erected, Vaabonbonphyllium gen. nov. from the Solomon Islands and Papua New Guinea and Rakaphyllium gen. nov. from New Guinea and the Aru Islands. Erection of these two new genera warrants the following new combinations: Rakaphyllium schultzei (Giglio-Tos, 1912), comb. nov., Rakaphyllium exsectum (Zompro, 2001b), comb. nov., and Vaabonbonphyllium groesseri (Zompro, 1998), comb. nov. Additionally, while reviewing material an undescribed Vaabonbonphyllium gen. nov. specimen was located and is herein described as Vaabonbonphyllium rafidahae gen. et sp. nov. from Mt. Hagen, Papua New Guinea. Additionally, a morphologically unique clade of several species recovered as sister to the Nanophyllium sensu stricto was recognized and their numerous unique morphological features and monophyly leads the authors to erect the new genus Acentetaphyllium gen. nov. which warrants the following new combinations: Acentetaphyllium brevipenne (Größer, 1992), comb. nov., Acentetaphyllium larssoni (Cumming, 2017), comb. nov., Acentetaphyllium miyashitai (Cumming et al. 2020), comb. nov., and Acentetaphyllium stellae (Cumming, 2016), comb. nov.

Full text

Abstract:

Abstract Background Phasmatodea (stick and leaf insects) play a central role on the debate regarding wing reduction and loss, and its wings are putative reacquisition from secondarily wingless ancestors based solely on extant species. A pivotal taxon in this respect is the species-poor Timematodea, consisting of approximately 21 wingless extant species, which form the sister group of all remaining winged or wingless stick and leaf insects, the Euphasmatodea. Results Herein, the new fossils of Timematodea from mid-Cretaceous Kachin amber are reported, with winged and wingless species co-occurring. The palaeogeographic distributions of all fossils of Holophasmatodea are summarized, showing their wide paleo-distributions. The phylogenetic analysis based on morphological characters confirms the earliest-diverging lineage of winged Breviala cretacea gen. et sp. nov. in Timematodea, and the possible relationships among all families of Holophasmatodea. These are critical for the reconstruction of patterns of wing evolution in early Phasmatodea. Conclusions The new fossils suggest that Timematodea once had wings, at least during the mid-Cretaceous. The palaeogeographic occurrences imply that Timematodea probably have been widely distributed since at least the Jurassic. The phylogenetic analysis with the ancestral-state reconstruction of wings indicates that the common ancestors of Holophasmatodea were winged, the reductions and losses of wings among Timematodea and Euphasmatodea have occurred independently since at least the Cretaceous, and the reduction or loss of the forewing earlier than the hind wings.

Abstract:

Abstract Background Phasmatodea are well known for their ability to disguise themselves by mimicking twigs, leaves, or bark, and are therefore commonly referred to as stick and leaf insects. In addition to this and other defensive strategies, many phasmatodean species use paired prothoracic repellent glands to release defensive chemicals when disturbed by predators or parasites. These glands are considered as an autapomorphic trait of the Phasmatodea. However, detailed knowledge of the gland anatomy and chemical compounds is scarce and only a few species were studied until now. We investigated the repellent glands for a global sampling of stick and leaf insects that represents all major phasmatodean lineages morphologically via µCT scans and analyzed the anatomical traits in a phylogenetic context. Results All twelve investigated species possess prothoracic repellent glands that we classify into four distinct gland types. 1: lobe-like glands, 2: sac-like glands without ejaculatory duct, 3: sac-like glands with ejaculatory duct and 4: tube-like glands. Lobe-like glands are exclusively present in Timema, sac-like glands without ejaculatory duct are only found in Orthomeria, whereas the other two types are distributed across all other taxa (= Neophasmatodea). The relative size differences of these glands vary significantly between species, with some glands not exceeding in length the anterior quarter of the prothorax, and other glands extending to the end of the metathorax. Conclusions We could not detect any strong correlation between aposematic or cryptic coloration of the examined phasmatodeans and gland type or size. We hypothesize that a comparatively small gland was present in the last common ancestor of Phasmatodea and Euphasmatodea, and that the gland volume increased independently in subordinate lineages of the Occidophasmata and Oriophasmata. Alternatively, the stem species of Neophasmatodea already developed large glands that were reduced in size several times independently. In any case, our results indicate a convergent evolution of the gland types, which was probably closely linked to properties of the chemical components and different predator selection pressures. Our study is the first showing the great anatomical variability of repellent glands in stick and leaf insects.

Abstract:

Abstract Background The re-evolution of complex characters is generally considered impossible, yet, studies of recent years have provided several examples of phenotypic reversals shown to violate Dollo’s law. Along these lines, the regain of wings in stick and leaf insects (Phasmatodea) was hypothesised to have occurred several times independently after an ancestral loss, a scenario controversially discussed among evolutionary biologists due to overestimation of the potential for trait reacquisition as well as to the lack of taxonomic data. Results We revisited the recovery of wings by reconstructing a phylogeny based on a comprehensive taxon sample of over 500 representative phasmatodean species to infer the evolutionary history of wings. We additionally explored the presence of ocelli, the photoreceptive organs used for flight stabilisation in winged insects, which might provide further information for interpreting flight evolution. Our findings support an ancestral loss of wings and that the ancestors of most major lineages were wingless. While the evolution of ocelli was estimated to be dependent on the presence of (fully-developed) wings, ocelli are nevertheless absent in the majority of all examined winged species and only appear in the members of few subordinate clades, albeit winged and volant taxa are found in every euphasmatodean lineage. Conclusion In this study, we explored the evolutionary history of wings in Phasmatodea and demonstrate that the disjunct distribution of ocelli substantiates the hypothesis on their regain and thus on trait reacquisition in general. Evidence from the fossil record as well as future studies focussing on the underlying genetic mechanisms are needed to validate our findings and to further assess the evolutionary process of phenotypic reversals.
