The new genus and species Margaritabruchus cherylae Romero and Johnson is described. It is distinct from other genera of bruchids because the ventral surface of the narrow hind femur is not in a gentle, convex curve. It is usually concave before and after an expansion near the middle that ends in a large, blunt, lateral spine about 0.66 from the base of the femur of both sexes. The hind femur of males has a hook-like spine on the lateral margin slightly beyond the blunt spine that is curved toward the base of the femur. The affinities of the genus are with other Acanthoscelidini and it is probably most closely related to Meibomeus and certainly to the very large New World genus, Acanthoscelides Schilsky. Margaritabruchus cherylae feeds in seeds of Indigofera densiflora M. Martens and Galeotti.

Staminodeus, new genus, is described for seven species: S. inermis, new species, from Panama; S. curvitibialis, new species, from Colombia and Venezuela; S. denticulatus, new species, from Costa Rica and Panama; S. bispinosus, new species, from Panama; S. forcipis, new species, from Costa Rica; S. dilatatus, new species, from Panama; and S. vectoris, new species, from Costa Rica and Panama. Staminodeus is placed in Derelomini, and is characterized by the putative synapomorphies: carinate rostrum, male with prothoracic leg ventrally denticulate (excepting S. inermis) as well as median lobe internally with complex structures, and female with frontal spine. All species are hypothesized to be associated with the staminodes of the inflorescences of Cyclanthaceae. Field observations on the reproductive behavior of S. vectoris at La Selva, Costa Rica, indicate that the protibia in males is used to displace competitors, whereas the spine in females was used as a point of support while transporting the detached staminodes to oviposition sites on the forest floor. A cladistic analysis with Notolomus basalis LeConte, Perelleschus carludovicae (Günther), and Systenotelus costaricensis Anderson & Gómez as outgroup taxa hypothesizes the phylogenetic relationships (S. inermis, ((S. curvitibialis, S. denticulatus), ((S. bispinosus, S. forcipis), (S. dilatatus, S. vectoris)))).

The following new species of Hemiphileurus are described: H. bispinosus Ratcliffe from Brazil, H. deslislesi Ratcliffe from Colombia, H. quadridentatus Ratcliffe from Guatemala, and H. warneri Ratcliffe from Mexico. The parameres of H. rugulosus Endrödi (Venezuela and Colombia) are illustrated to enable easier identification of this species, and H. kahni Dupuis and Dechambre is redescribed and recorded from Brazil for the first time. Diagnostic illustrations of the male parameres are provided for the above taxa. A checklist for all the species in the genus is given.

Aphodius (Bodilus) kaznakovi Frolov, new species, from central China (Qinghai Province) is described and illustrated. The new species is compared with closely related A. (B.) sordescens Harold.

Harpalus (Pseudoophonus) poncei new species is described from Florida, USA, based on three specimens, all collected in 1963. This species may be a Florida endemic overlooked by collectors or an undescribed adventive species.

Six new species of Euscelus Schoenherr from Central America are described, illustrated and mapped: E. oaxacensis new species, E. stockwelli new species, E. similis new species, E. spinosus new species, E. bivittatus new species, and E. maculicollis new species. These new species and new records for E. submaculatus Voss and E. vittaticollis Voss, previously known only from South America, brings the total number of euscelines in Central America to 22. Male genitalia, including unique endophallic structures, are illustrated for each new species. A key based on external characters is provided to separate the new species from all known Central American euscelines.

The larva of Babalimnichus masamii M. Satô is described. This larva is the first record of the genus and subfamily Thaumastodinae, and is quite easily distinguished from the previously known limnichid larvae in having the mandibular basal process setose.

Presumed to be extinct by some authors, Anomala exigua (Schwarz) was rediscovered in central Florida. A diagnosis of males and females is presented, including a note on the brachypterous female. Comments are made on attempts to find the type locality. Observations on habitat preferences and behavior are discussed.

The long-lipped beetle family Telegeusidae is reported for the first time from Texas and is represented in that state by the new species Telegeusis texensis Fleenor and Taber. The biology and literature of this rare genus are reviewed.

New species of Phyllophaga Harris in the subgenera Phyllophaga (s.str.) and Phytalus Erichson are described from the montane cloud forests located at 1,900–2,300 m of altitude in the Biosphere Reserve Sierra de Manantlán, Jalisco-Colima, México. Phyllophaga (s.str.) sayloriana new species and P. (s.str.) manantleca new species are included in the “pubicauda” species group; P. (s.str.) joyana new species is included in the “xanthe” species group; P. (Phytalus) dugesiana new species and P. (Phytalus) jalisciensis new species are included in the “bucephala” species group. Drawings of male genital capsules, tarsal claws, and female genital plates of the new species are provided.

Lyreus alleni Ivie and Ślipiński, new species, is described from a limestone sinkhole in Alabama. This is the first record of the genus from the New World. Illustrations of the new species and the European L. subterraneus Aubé are provided to aid in identification.

In this paper, Onthophilus lijiangensis, new species, is described based on specimens from Yunnan Province, China. Onthophilus silvae Lewis and O. ordinarius Lewis are newly recorded from China. Thus, the Chinese species of Onthophilus are increased to seven. A key to species is given. Type specimens are deposited in the Institute of Zoology, Academia Sinica.

Epitragosoma arenaria new genus and new species, an unusual brachypterous beetle in the tribe Epitragini, is described. It is locally abundant in the Llano Estacado area of western Texas on stems of the dune-stabilizing grass, Panicum havardii Vasey.
