Diolcus thomasi Eger new species (Hemiptera: Heteroptera: Scutelleridae: Pachycorinae), is described from Cayman Brac and Little Cayman Island and compared to D. chrysorrhoeus (Fabricius), its closest congener. Nesogenes boscii (Fabricius) is removed from the Elvisurinae and placed in the Pachycorinae. The relationship of N. boscii to D. thomasi and D. chrysorrhoeus is discussed.

The following Silvaninae (Coleoptera: Silvanidae) are included: Synobius Sharp, 1899, with its species, Synobius lobicollis Sharp, 1899 and Synobius lobatus (Grouvelle, 1896); Neocorimus thomasi, new genus and new species; Austronausibius wagneri (Grouvelle) new combination, a species originally placed in Nausibius Lentz by Grouvelle (1913); a third species of Pensus Halstead, 1973, is described, Pensus hirtus new species, and a short key given for distinguishing it from the already known species, Pensus gilae (Casey) and Pensus guatemalenus (Sharp); also Coccidotrophus Schwarz and Barber, 1921,including Coccidotrophus socialis Schwarz and Barber, 1921, Coccidotrophus cordiae Barber, 1928, Coccidotrophus wheeleri (Schwarz and Barber) new combination (a species originally placed in Eunausibius Grouvelle by Schwarz and Barber (1921)) plus two new species, Coccidotrophus platyops, new species;Coccidotrophus trinidadensis, new species making a total of five in this genus; other taxa included are, Eunausibius Grouvelle, 1913, with its described and a new species as follows, Eunausibius tenebrionoides (Grouvelle), Eunausibius jatahyensis, new species, Eunausibius elongatus (Grouvelle); and finally Annomus bolivianus, new genus and new species. Additionally, taxonomic changes are made for two species originally described in Eunausibius: Nausibius lophius (Parsons) new combination (= Eunausibius lophius Parsons) and Nausibius salutaris (Parsons) new combination (= Eunausibius salutaris Parsons). Descriptions, diagnoses, and illustrations (habitus and male genitalia line drawings plus four color habitus photographs) are provided.

Two new species of Carpophilus Stephens, 1829 in the subgenus Ecnomorphus Motschulsky, 1858 (Coleoptera: Nitidulidae) were recovered in material from the Caribbean. Descriptions and detailed diagnoses are provided for Carpophilus (Ecnomorphus) jamaicensis Powell and Schnepp, new species and Carpophilus (Ecnomorphus) thomasi Powell and Schnepp, new species. A key to the Carpophilus (Ecnomorphus) of the West Indies is appended.
839
Glaresis franki Keller and Skelley new species and Glaresis thomasi Keller and Skelley new species (Coleoptera: Scarabaeoidea: Glaresidae) are described and illustrated. They represent the first record of the family for the West Indies. Both species are placed into the phoenicis species group. A key to the two West Indies species is presented.

837
Two species of the early-diverging lineages of Pharaxonotha Reitter (Coleoptera: Erotylidae: Pharaxonothinae) are described: Pharaxonotha taylori Skelley and Tang, new species, and Pharaxonotha thomasi Skelley and Tang, new species. A new key to described species of Pharaxonotha, based on previously unused characters, is presented.

Dyslexia Skelley and Gasca-Álvarez, new genus (Coleoptera: Erotylidae: Erotylinae: Erotylini), is described and illustrated. The genus is comprised of four new species, all described by Skelley and Gasca-Álvarez: D. belamyi, D. dathomirria, D. pulcricolor, and D. tomasi. The unique broad head structures of this genus are characterized and compared with other genera. Problems associated with the taxonomy of Erotylini are discussed.

Description of two new genera and a taxonomic key to the world genera of Cybocephalidae (Coleoptera)
(2020)
The sixteen genera of Cybocephalidae (Coleoptera) occurring worldwide are listed and keyed. The genera included are Amedissia Kirejtshuk and Mantič, Apastillus Kirejtshuk and Mantič, Cybocephalus Erichson, Endrodiellus Endrödy-Younga, Eupastillus Lawrence, Hierronius Endrödy-Younga, Horadion Endrödy-Younga, Pacicephalus Kirejtshuk and Mantič, Pastillocenicus Kirejtshuk and Nel, Pastillodes Endrödy-Younga, Pastillus Endrödy-Younga, Pycnocephalus Sharp, Taxicephomerus Kirejtshuk, Theticephalus Kirejtshuk, a description of a new genus, Microthomas T. R. Smith, with one new species, M. brevicornis T. R. Smith, from Bolivia, and a new genus, Conglobatus T. R. Smith, with two new species, C. armatus T. R. Smith from Central and South America and C. fullertoni T. R. Smith from Dominica. A key to genera, illustrations of morphological features, and distributional data are provided. The genus Nodola Bréthes is found to be a new synonym of Cybocephalus Erichson. The transfer of Nodola chilensis Bréthes into Cybocephalus creates a secondary homonymy with C. chilensis Reitter. Nodola chilensis Bréthes is here given a new name, Cybocephalus brethesi T. R. Smith.

The two new species Phyllobaenus thomasi (Campeche, Oaxaca, Quintana Roo and Yucatán, Mexico, and Belize) and P. turnbowi (San Luis Potosi, Mexico), are described (Coleoptera: Cleridae: Hydnocerinae: Hydnocerini). The primary types are photographed and intrageneric relationships of the species are discussed.

The Colaspis suilla species group (Coleoptera: Chrysomelidae: Eumolpinae) is defined relative to other species of the genus Colaspis Fabricius occurring in the United States. The group is composed of five species, of which three from Florida are described as new species: C. ansa Riley from the Florida Panhandle, C. skelleyi Riley from Central Florida, and C. thomasi Riley from the southern Lake Wales Ridge. Colaspis suilla borealis Blake is reduced to a full synonym of C. suilla Fabricius, new synonymy. Comparative remarks, habitus images, images of male and female genitalia, range maps, specimen data, and a key to species are presented.

Nothochodaeus marsupialis Paulsen, new species (Coleoptera: Ochodaeidae), is described from Aceh Province, Indonesia, on the island of Sumatra. The species possesses deep abdominal cavities behind a shield-like central process, as well as rows of conical tubercles laterally on the second and third ventrites. These structures have not been found in any other members of the genus or family.

Four online photographs from Oaxaca, Mexico taken by N. R. Jenzen-Jones and posted on inaturalist.org reveal Selenops sp., probably S. mexicanus Keyserling (Arachnida: Araneae: Selenopidae), as a new host spider species, genus and family for the common and widespread American spider wasp Tachypompilus ferrugineus (Say) (rusty spider wasp). The wasp transported the immobilized spider up an exterior stucco wall of a house, dorsal side upward, walking backwards for 3m to her nest in a gap between the wooden planking and stucco wall beneath the roof, while grasping the femur of its right pedipalp with her mandibles.

New species of Trachyderini from Mexico and Central America (Coleoptera: Cerambycidae: Cerambycinae)
(2020)
Three new trachyderine species in the subtribe Trachyderina (Coleoptera: Cerambycidae: Cerambycinae: Trachyderini) are described: Entomosterna kovariki Wappes and Santos-Silva, new species, from Belize; Gortonia sumideroensis Wappes and Santos-Silva, new species, from Mexico (Chiapas); and Sphaenothecus vandenberghei Wappes and Santos-Silva, new species, from Nicaragua. A new key to Entomosterna species, and a previous Sphaenothecus key by Chemsak and Noguera (1998) is modified to include the new species, with both provided herein.
