The Prioninae (Cerambycidae) of Hispaniola are reviewed. Twenty-eight species are known from the island, including six new species and a new genus described herein: Elateropsis dichroma Lingafelter, new species, Elateropsis woodleyi Lingafelter, new species, Solenoptera tomentosa Lingafelter, new species, Solenoptera helbi Lingafelter, new species, Solenoptera rugosa Lingafelter, new species, and Derancistrachroma melanoleuca Lingafelter, new genus and new species. Derancistrus furfurosus Galileo and Martins, 1993 is transferred to Solenoptera Audinet-Serville, 1832 as S. furfurosa, new combination; the holotype is determined to be a female, and the male is described for this species. Derancistrodes vittatus (Olivier, 1795) is transferred to Solenoptera as S. vittata, new combination, and Derancistrodes Galileo and Martins, 1993 is a new synonym of Solenoptera. New country records are recorded for Strongylaspis corticarius (Erichson, 1848), Monodesmus atratus Fisher, 1932, Elateropsis quinquenotatus Chevrolat, 1862, Elateropsis sericeiventris Chevrolat, 1862, and Elateropsis trimarginatus (Cazier and Lacey, 1952). The first known female of E. trimarginatus is described. Diagnoses and discussions are provided for each species. A key to all the Prioninae known from Hispaniola is included.

Penichrolucanus alleni Bartolozzi, new species from the Philippines is described and compared to the more closely related species of the genus. The new taxon belongs to the “copricephalus group” having an eight-segmented antenna but possesses a distinctive two-articulated club. A key to all the known species of the genus is also provided.

Three new species of Lamiinae are described and illustrated: Adetus mirabilis Martins, Galileo, and Santos-Silva (Apomecynini) and Euryestola skillmani Martins, Galileo, and Santos-Silva (Calliini) from Bolivia; and Esthlogena (Esthlogena) crassa Martins, Galileo, and Santos-Silva (Pteropliini) from Mexico and Guatemala. Euryestola skillmani is included in an existing key.

Two new species of the pselaphine beetle genus Batriscenellus Jeannel (Coleoptera: Staphylinidae: Pselaphinae: Batrisitae: Batrisini), Batriscenellus abdominalis Yin and Wang, new species from Zhejiang, eastern China, and Batriscenellus hongkongensis Yin and Wang, new species from Hong Kong, southern China, are described, illustrated, and compared with related congeners. A previously published key to the Batriscenellus species of China is modified to accommodate the new taxa.

When attempting to understand a species' distribution, knowing how many collections should be surveyed to achieve an adequate sample (exhaustiveness) is important. A test for exhaustiveness using species distribution models created with Diva-GIS was performed on county level locality information recorded from more than 4,900 specimens of Thoracophorus costalis Erichson (Staphylinidae: Osoriinae) borrowed from 38 collections. Size and location of distribution models based on specimens from single collections varied greatly, indicating “collection bias.” At least 15 collections needed to be combined before the resultant model averaged 90% of the area of a reference model created from all available specimens. By themselves, alternative distribution data from literature, Bugguide.net, and GBIF.org performed poorly, resulting in models with less than 15% the area of the reference model. Comments on the use of online data, the importance of maintaining and growing regional collections, and the future of natural history collections are included.

This study describes the morphometries and chorion microsculpturing of the eggs of 12 species of Melolonthinae and Rutelinae (Coleoptera: Scarabaeidae) belonging to seven genera. Egg size, shape, and color vary among species, and the chorion microsculpturing exhibits variation among and within genera. The length/width ratio was comparatively higher in Lepidiota mansueta Burmeister and Maladera insanabilis (Brenske) (Melolonthinae) while lowest in species of Anomala Samouelle (Rutelinae). Shape was elliptical to cylindrical in Melolonthinae and spherical in Rutelinae. Diagnostic characters with respect to chorion microsculpturing analyzed at the subfamily and species levels revealed variation in patterns exhibiting reticulations in Melolonthinae to projections/protuberances in Rutelinae, respectively. Among melolonthines, the reticulations differed in shape and relief. In rutelines, consistency in protuberances was observed within the genera but varied among genera. These variations in microsculpturing might enable identification of taxa in their egg stage to subfamily, generic, and/or species levels.

Recent systematic and morphological studies on the family Noteridae have suggested that the Neotropical species Noterus buqueti Laporte, 1835 does not fit within the generic limits of Noterus Clairville, 1806 or any other currently described genera within the family. The burrowing water beetle genus Canthysellus Baca and Toledo, new genus (Coleoptera: Noteridae: Noterini) is erected to accommodate this species, Canthysellus buqueti (Laporte, 1835), new combination and two new species: Canthysellus sipaliwini Baca and Toledo, new species (Suriname) and Canthysellus peruanus Baca and Toledo, new species (Peru). Habitus photographs, illustrations of diagnostic characters, distributions, habitat photographs, and a key to all known species of Canthysellus are provided.

The second and third instars of Yola wraniki Wewalka, 2004 are described and illustrated for the first time, with detailed morphometric and chaetotaxic analyses of the cephalic capsule, head appendages, legs, last abdominal segment, and urogomphi. The mature larva of Yola Gozis, 1886 can be distinguished from those of the other known Bidessini genera by the following combination of morphometric and chaetotaxic characters: ratio length of metathoracic leg/head width greater than 2.85; ratio length of urogomphus/head width greater than 2.70; absence of a ventroapical spinula on third antennomere; secondary temporal spine-like setae on parietale; natatory setae on tibia; secondary posteroventral setae on tarsus and secondary setae on urogomphus; presence of pore PAk and secondary dorsal setae on protarsus; and mandibular pore MNa located in a clearly distal position with respect to pore MNb. A key for the identification of the third instars of the genera of Bidessini known in detail is provided.

Belladessus Miller and Short, new genus, is described to include two new species of diving beetles, B. femineus Miller and Short, new species (southeastern Venezuela and Suriname) and B. puella Miller and Short, new species (western Venezuela). The genus is placed in the dytiscid tribe Bidessini due to the presence of a distinctive spermathecal spine, among other diagnostic features. The genus is characterized by the absence of an occipital line, presence of basal pronotal striae, presence of a basal elytral stria, absence of a sutural elytral stria, absence of a transverse carina on the elytral epipleuron at the humeral angle, and presence of a distinct marginal bead on the anterior clypeal margin. No male specimens are present among the more than 125 specimens known, and, from this, it is hypothesized that the species are likely parthenogenetic.

Zimpherus nancae Miller and Wheeler, new genus and new species (Coleoptera: Dytiscidae: Hydroporinae: Bidessini) is described from Cerro de Neblina, Amazonas, Venezuela. Habitus, male genitalia, and other diagnostic features are illustrated.
