“…According to the keys provided by Lawrence (1980), Ślipiński & Burakowski (1988) and Ivie et al (2016), the new fossil can be easily ruled out from all other colydiine tribes except Synchitini, based on characters including body surface with recumbent setae, antennae 11-segmented with 3-segmented club, procoxal cavities open, metanepisterna narrow, and tibiae simple. The fossil can be further keyed to the entry of Bulasconotus with the key provided by Ślipiński & Lawrence (1997), although this key was designed for Australo-Pacific taxa only.…”

“…Remaks: Bulasconotus is known in the Recent fauna as two described species living in the Melanesian islands (Ślipiński & Lawrence, 1997;Bernard & Gillett, 2020). The presence of B. scaccarius in Hawaii was thought to be invasive.…”

“…This group had long been treated as an independent family (Colydiidae) in the earlier works (e.g., Pope, 1961;Dajoz, 1977Dajoz, , 1980Stephan, 1989;Ivie & Ślipiński, 1990). Ślipiński & Lawrence (1999) merged Colydiidae into Zopheridae based on a morphological phylogenetic analysis, although the analysis suffered from potential defects in taxon sampling and character coding (Ivie et al, 2016). The close relationship between Colydiinae and Zopherinae has been supported by molecular studies (McKenna et al, 2019;Cai et al, 2022).…”

A fossil species of the extant colydiine genus Bulasconotus Ślipiński & Lawrence, B. carinisternus Li, Ślipiński & Cai sp. nov., is reported from mid-Cretaceous Kachin amber of northern Myanmar. The new species shares with extant Bulasconotus the 3-segmented antennal club, externally open procoxal cavities, and similar sculpture on the pronotum and elytra, but could be recognized by the medially carinated prosternal process. The present discovery provides a valuable example of morphological stasis in the cylindrical bark beetles.

“…Interesting morphological modifications can be found within the subfamily Inopeplinae (Salpingidae), which encompasses beetles with flattened bodies and with various degrees of elytral shortening, resulting in a rove‐beetle‐like appearance (Ślipiński et al, 2021). This modification is most likely attributed to life under bark (Ślipiński et al, 2021) and selective pressure on higher body flexibility. Another genus of salpingids, Aegialites Mannerheim (subfamily Aegialitinae), which inhabit intertidal rocks in the northern Pacific region, contains species with variably truncate elytra loosely exposing the pygidium.…”

When a key innovation becomes redundant: Patterns, drivers and consequences of elytral reduction inColeoptera

The transformation of the fore wings into strongly sclerotized protective covers (elytra) is considered a fundamental evolutionary innovation of the megadiverse order Coleoptera. Surprisingly, these multifunctional structures have been reduced in many distantly related groups of beetles. Patterns, drivers and the evolutionary implications of this modification have never been comprehensively discussed. In the present study, we surveyed the entire order Coleoptera to analyse the patterns of elytral shortening and loss, with a special focus on prevalence, forms, degree of reduction and the functional background of this significant deviation from the coleopteran ground plan. Our analysis revealed that about 20% of all extant species (roughly 88,000 out of 442,275 spp.), distributed across all four suborders, have shortened or even absent elytra. The elytral loss was more frequent within the polyphagan series Elateriformia and Staphyliniformia. Moreover, we found that elytral reduction has independently occurred multiple times in the evolutionary history of Coleoptera and that it has been driven by a wide array of selective drivers. One of the main drivers is the improved flexibility of the uncovered abdomen and the correlated increased manoeuvrability in narrow spaces, as well as the option of using the flexible abdomen as a steering organ or to facilitate mating. Another common driver is mimicry, where exposed metathoracic wings potentially improve the overall similarity to hymenopteran models. Exposure of the abdomen can facilitate the targeted release of defensive abdominal gland secretions and was most likely a crucial step towards establishing relations with social insects enhanced by chemical communication. In the Elateriformia, and rarely in other lineages, elytral loss is a consequence of paedomorphosis, related to a specific resource‐allocation strategy. In many groups of beetles with reduced elytra, alternative defensive strategies can be found. This includes, for instance, aposematic coloration, chemical defence, mimicry or bioluminescence. Direct drivers of elytral loss in many groups remain unclear, and more studies are needed to understand the evolutionary background and implications of this significant morphological modification in Coleoptera.
