Box 141874 Gainesville, FL 32614-1874 USA http://www.centerforsystematicentomology.org/ Insecta Mundi is a journal primarily devoted to insect systematics, but articles can be published on any non- marine arthropod. Topics considered for publication include systematics, taxonomy, nomenclature, checklists, faunal works, and natural history. Insecta Mundi will not consider works in the applied sciences (i.e. medical entomology, pest control research, etc.), and no longer publishes book reviews or editorials. Insecta Mundi pub- lishes original research or discoveries in an inexpensive and timely manner, distributing them free via open access on the internet on the date of publication. Insecta Mundi is referenced or abstracted by several sources including the Zoological Record, CAB Abstracts, etc. Insecta Mundi is published irregularly throughout the year, with completed manuscripts assigned an indi- vidual number. Manuscripts must be peer reviewed prior to submission, after which they are reviewed by the editorial board to ensure quality. One author of each submitted manuscript must be a current member of the Center for Systematic Entomology. Manuscript preparation guidelines are availablr at the CSE website.

Chromosomes of four rare and localized Caribbean Prioninae (Coleoptera: Cerambycidae) species were analysed. All have 26, XY karyotypes. Those of Solenoptera canaliculata (Solenopterini) from Guadeloupe nearby islands Les Saintes and Marie-Galante and S. quadrilineata from Martinique look similar. They have a single pair of sub-metacentric autosomes. The karyotype of S. touroulti from St. Lucia has three sub-metacentric pairs. It appears closer to that of Hovorodon maxillosum (Mallodontini) from Marie-Galante which has ten sub-metacentric pairs. The CO1 gene sequence, taking two European species Aegosoma scabricorne (Prioninae: Aegosomatini) and Ergates faber (Prioninae: Ergatini) as external groups was analysed in S. canaliculata and S. quadrilineata. In spite of their karyotype similarity, their CO1 genes differ by a strong accumulation of mutations. Thus, either chromosomal or genetic data confirm the species status of the three closely related Solenoptera species. Ten different CO1 haplotypes are found among the 21 specimens of S. canaliculata studied from les Saintes and Marie-Galante. Both different haplotypes were found in each island and identical haplotypes were found in different islands. Hence, the gene flow was not interrupted. Biogeographical parameters favor the hypothesis that repeated passages between islands were made possible by floating trunks, principally from Les Saintes to Marie-Galante. Key Words.

Introduction The genus Solenoptera Audinet-Serville, 1832 belongs to the tribe Solenopterini, one of the 21 tribes of Prioninae longhorn beetles (taxonomy following Tavakilian and Chevillotte 2012). This tribe com- prises six other genera (Derancistrodes Galileo and Martins, 1993, Derancistrus Audinet-Serville, 1832, Elateropsis Chevrolat, 1862, Holonotus Thomson, 1861, Prosternodes Thomson, 1861 and Sphenostethus Haldeman, 1848) and is composed of 47 species spread in the Antilles and in the American continent from southern USA to Colombia. The genus Solenoptera includes 16 species, 8 of which occur in Lesser Antilles, 5 in Greater Antilles, 2 in both Lesser and Greater Antilles and one in Colombia.
