Here we report on a new firefly species, Photinus interdius, which is remarkable for its fully diurnal and luminescent courtship protocol. Males slowly flew near the ground searching for receptive females and emitted 800 ms, bright yellow light flashes at 3–4-s intervals. Male flights occurred as early as 13:10 and ceased before 18:00. We sequenced two mitochondrial loci and one genomic locus and combined these with those from 99 specimens representing 45 Photinus and 25 related firefly species. Bayesian inference resulted in a well-resolved phylogeny that placed this new species as the closest relative of, but basal to the Photinus clade. We propose that the adaptive significance of this extraordinary temporal shift in courtship niche is the outcome of a selective landscape that has optimized the trade-off between reduced predation risk and ease of mate-localization.","PeriodicalId":54975,"journal":{"name":"Insect Systematics & Evolution","volume":"48 1","pages":"512-531"},"PeriodicalIF":1.2,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/1876312X-48022162","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45503782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the reduced size, the morphology of the maxillolabial complex of scelionids is very diverse and phylogenetically informative. 81 characters are scored for 129 genera (representing 75% of the total number of known extant genera of scelionids), as well as for seven outgroup taxa. All taxa examined are illustrated with images, SEM micrographs and/or line drawings. Phylogenetic trees resulting from analyses conducted in TNT under various settings were not fully resolved, but some relationships were repeatedly retrieved. The Platygastroidea are usually corroborated. Nixoniini, Sparasionini, Plaumannion and Huddlestonium are frequently retrieved as the most basal platygastroid lineages. Psix and Paratelenomus often form a monophyletic group close to Gryonini. The Scelioninae, Teleasinae and Telenominae are not supported as monophyletic. However, some major scelionid clades are frequently retrieved, but these are not recognized in the current classification of Platygastroidea. The evolution of the palpal formula, highly variably in scelionids, and previously used in platygastroid systematics, is explored. The number of maxillary palpomeres in the ground plan of platygatroids is probably five, that of labial palpomeres two or three, given the variation among basal scelionids. Our study provides relevant information for resolving the phylogeny of the Platygastroidea, but additional character sources have to be explored to obtain a robust phylogenetic hypothesis.","PeriodicalId":54975,"journal":{"name":"Insect Systematics & Evolution","volume":"48 1","pages":"315-439"},"PeriodicalIF":1.2,"publicationDate":"2017-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/1876312X-48022156","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44207302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(Diptera: Fergusoninidae) from Leptospermum madidum A.R. Bean in far north Queensland and a new species of nematode, Fergusobia leptospermum Davies sp.n. (Tylenchida: Neotylenchidae) from L. laevigatum (Gaertn.) F. Muell. in southern Victoria, Australia are described. These represent the first species of the Fergusonina fly/ Fergusobia nematode mutualism to be described from the genus Leptospermum (Myrtaceae). Fergusonina madidum sp.n. forms lateral and terminal multilocular shoot bud galls enclosed in subterminal leaflets. It can be distinguished from all other species of Fergusonina by the lack of dorsal setae on abdominal segment 7 of the female. Unlike most described species of Fergusonina it also lacks the posterior cross vein m-cu in the wing. It shares this character with F. giblindavisi Taylor and F. thomasi Taylor from flower bud galls on Corymbia , but both these species are large and abdominal segment 7 of females is densely setose. Its larva is unknown but from the morphology of puparia the dorsal shield comprises 3 broad transverse bands comprising lateral rows of raised ridge-like sclerotised spicules. Its associated species of nematode is not known. Fergusobia leptospermum sp.n. is associated with cryptic lateral and terminal usually unilocular shoot bud galls. It is characterised by the combination of an open to tight C-shaped parthenogenetic female having a small ‘a’ ratio, with a short but sturdy stylet, flat anterior end; huge dorsal pharyngeal gland, reproductive system with a relatively long uterus, and a sub-conoid tail with a broadly rounded tip; a C-shaped infective female with an almost hemispherical tail tip which may or may not be ventrally hooked; and an open C-shaped male with angular spicules and peloderan bursa arising near the anterior end, and a relatively long (c’ = 2.2–3.2) sub-conoid tail with a bluntly to broadly rounded tip. Its status as a distinct species is confirmed by molecular analyses. Its associated species of fly is known only from several larvae and a puparium, and remains undescribed. The dorsal shield of this Fergusonina species comprises 7 broad bands, the first six having heavily sclerotised raised ridges and the seventh with a medial field of weak spicules. The widely separated collection localities, together with the large number of species in Leptospermum suggest that the mutualism is likely to be speciose and occupy a broad geographic range on this host.","PeriodicalId":54975,"journal":{"name":"Insect Systematics & Evolution","volume":"49 1","pages":"183-206"},"PeriodicalIF":1.2,"publicationDate":"2017-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1163/1876312X-00002166","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46992929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
