Paleontology of leaf beetles

`The rate of evolution in any large group is not uniform; there are periods of relatise stability, and periods of comparatively rapid change.' Cockerell and LeVeque, 1931 To Yenli Ych, my beloved wife, a most wonderful person! The fossil record of the Chrysomelidae can be tentatively traced back to the late Paleozoic to early Mesozoic Triassic. Mesozoic records at least 9 subfamilies, 19 genera, and 35 species, are represented by the Sagrinae, the exclusively Mesozoic Proto scelinae, Clytrinae, Cryptocephalinae, Eumolpinae, Chrysomelinae. Galerucinac, Alticinae, and Cassidinae. Cenozoic records at least 12 subfamilies- 63 % of the extant- 12! genera, and 325 species, include the same extant subfamilies as well as the Donaciinae, Zeugophorinae, Criocerinae, and Hispinae and can be frequently identified to genus, especially if preserved in amber. Quaternary records are often identified to extant species. tn total, at least t3! genera about 4 % of total extant, and 357 species < 1 % have been reported. At least, 24 genera <1 % of the extant seem to be extinct. Although reliable biological information associated with the fossil chrysomelids is very scarce, it seems that most of the modern host-plant associations were established, at least, in the late Mesozoic to early Cenozoic. As a whole, stasis seems to be the general rule of the chrysomelid fossil record. Together with other faunal elements, chrysomelids, especially donaciines, have been used as biogeographic and paleoclimatological indicators in the Holocene. I

Eine neue Dactylochelifer-Art aus Spanien (Prov. Tarragona) (Pseudoscorpiones)

Auf einer Reise zusammen mit J. SCHEUERN in Spanien konnte neben zahlreichen, mediterran weiter verbreiteten- Arten im Ebro-Delta eine neue Dactylochelifer- Art aufgesammelt werden. Möglicherweise ist das Verbreitungs gebiet dieser Art recht beschränkt, sonst wäre sie wohl schon früher im verhältnismäßig gut durchforschten Spanien (insbesondere Mittelmeerküste) gefunden worden. Erst vor kurzer Zeit hat MAHNERT (1978) die im westlichen Mediterraneum und in Nordafrika lebenden Arten dieser Gattung zusammenfassend behandelt, die genauen Verbreitungsgebiete dieser Arten sind jedoch noch unbekannt.Peer reviewe

Spiloscapha bryanti, sp. n.

<i>Spiloscapha bryanti</i> sp. n. <p>(Fig. 8)</p> <p> <b>Type material.</b> <b>Holotype: JAVA</b>, ♀, Kawah Manoek, 10.IV.1909, leg. G. E. Bryant, BMNH.</p> <p> <b>Description.</b> Shape and colour pattern of pronotum and elytra see Fig. 8. Head, pronotum, and scutellum brown; elytron brown with a black spot in the posterior part not reaching tip, lateral margin, suture and ventral side of body brown. Head with similar punctation as on pronotum; antenna bicoloured with antennomeres 1–4 brown and antennomeres 5–11 dark brown. Pronotum with fine punctures, distance between punctures 2–8 times longer than puncture diameter, surface between punctures distinctly shagreened; anterior margin medially unbordered, basal margin unbordered. Elytron with 8 somewhat irregular rows of punctures without striae, third row with approximately 38 punctures; intervals flat, with a few scattered punctures, surface between punctures shining; lateral margin visible from dorsal nearly on its entire length. Punctures on metaventrite and abdominal ventrites distinctly coarser laterally than medially. Aedeagus unknown, only female available. Body length 3.0 mm.</p> <p> <b>Diagnosis.</b> <i>Spiloscapha bryanti</i> <b>sp. n.</b> can be recognized by its body shape and dorsal colour pattern. The colour pattern of <i>S. bryanti</i> <b>sp. n.</b> is similar to that of <i>S. palawanica</i> Schawaller, 2004 from the Philippines (Palawan), but the latter species is distinctly flatter, more elongate and parallel sided, the surface between the pronotal punctures is shining, the elytral intervals are posteriorly slightly convex, and the dark elytral spot reaches the lateral margin and suture. The other known species from Java, <i>S. javanicum</i> Gebien, 1925 has a completely different dorsal colour pattern (figured in Schawaller 1997), and also a longer body shape.</p> <p> <b>Etymology.</b> Named in honor of Gilbert Ernest Bryant (1878–1965), former entomologist in BMNH, specialist of Chrysomelidae and collector of the holotype.</p>Published as part of <i>Schawaller, Wolfgang, 2012, New species and records of the genus Spiloscapha Bates (Coleoptera: Tenebrionidae) from the Oriental and Papuan Regions (part 2), pp. 62-68 in Zootaxa 3336 (1)</i> on pages 62-64, DOI: 10.11646/zootaxa.3336.1.4, <a href="http://zenodo.org/record/211183">http://zenodo.org/record/211183</a&gt
