A revision of the neotenic genus Scarelus(Coleoptera: Lycidae)
Open accessAbstract
The neotenic net-winged beetle genus Scarelus Waterhouse 1878 is revised and its relationships to other genera of Ateliini, biology, and zoogeography are discussed. Twenty-seven species of Scarelus are recognized, of which eleven are described as new: S. baranciki n. sp.(Borneo), S. pseudoumbrosus n. sp. (Malaysia), S. cibodasensis n. sp.(Java), S. flavicollis n. sp. (Sumatra), S. loksadoensis n. sp. (Borneo), S. pahangensis n. sp. (Malaysia), S. ruficollis n. sp. (Sumatra), S. rufus n. sp. (Sumatra), S. salvani n. sp. (Philippines), S. saranganensis n. sp. (Java), and S. similis n. sp. (Borneo). Scarelus luchti Kazantsev & Yang 1999 is considered to be a nomen nudum due to proposal without any description. All known species are listed with differential diagnoses, redescriptions, data on variability and distribution. A key to Scarelus species and Ateliini genera is provided.

A total lack of metamorphosis via type II paedomorphosis is strongly suspected in at least three other lineages within the Lycidae alone.
“Outside of the Platerodrilini, a total lack of metamorphosis via type II paedomorphosis is strongly suspected in at least three other lineages within the Lycidae alone (Levkanicova & Bocak, 2009; Malohlava & Bocak, 2011; Masek et al. , 2014).”

The Natural history section (page unavailable) says the authors suspect sexually mature Ateliini females remain larviform, but that female neoteny has not been proven by observation. This supports Ateliini as one suspected lycid lineage outside Platerodrilini; the paper does not establish a total lack of metamorphosis, identify it as type II paedomorphosis, or substantiate the count of at least three lineages. (LLM, conf=0.85)
Experimental — accuracy not yet measuredFor many groups, such as Scarelus or Telegeusidae, while extreme paedomorphosis and total avoidance of pupation are suspected, the exact status of pupation and the putative terminal stage when females attain reproductive maturity remain unknown.
“Unfortunately, for many groups, such as Scarelus (Lycidae) (Malohlava & Bocak, 2011) or the Telegeusidae (Jeng, 2008), while extreme paedomorphosis and total avoidance of pupation are suspected, the exact status of pupation and the putative terminal stage when females attain reproductive maturity remain unknown.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
