The new genus Neotrichaphodioides and the new species N. woytkowskii from Peru are described. Aphodius caracanus Balthasar, A. ecuadoriensis Petrovitz, A. forsterianus Balthasar, and A. volxemi Harold are redescribed and figured, and transferred into Neotrichaphodioides, all becoming new combinations. New synonymies of Aphodius martinsi Petrovitz with N. caracanus (Balthasar) and Aphodius squamifer Petrovitz with N. volxemi (Harold) are presented. The lectotype of A. volxemi is here designated.

Sundapyrochroa, a new genus of pyrochroine Pyrochroidae, is described from three Sunda Shelf species most recently assigned to Pseudopyrochroa Pic: Sundapyrochroa atricolor (Pic), comb. nov., recorded from Peninsular Malaysia, Sundapyrochroa nigripennis (Pic), comb. nov., recorded from Peninsular Malaysia, and Sundapyrochroa sumatrensis (Pic), comb. nov., recorded from Borneo (Malaysia: Sabah) and Sumatra (Indonesia). Schizotus rotundicollis Pic, syn. nov., is proposed as a junior synonym of S. sumatrensis. No evidence could be found to support subspecifi c categories for S. nigripennis, thus, Pseudopyrochroa nigripennis notaticeps Pic, syn. nov., is proposed as a junior synonym of S. nigripennis. Gross anatomy of the cranium (female, male), antennae (female, male), and genitalia (male) are both diagnostic and enigmatic, suggesting no clear relationships with other pyrochroine genera.

Pyroghatsiana, a new genus of pyrochroine Pyrochroidae is described from the Southern Ghats of the Indian continental southern tip. The only known specimen is a female, Pyroghatsiana madurensis (Pic), new combination, originally placed in Dendroides Latreille, and subsequently transferred to Pseudodendroides Blair. Several striking differences including the dorsal interocular width between the compound eyes, shape and length of the third antennal segment, and shape of the pronotum preclude placement of Pyroghatsiana in either Dendroides, Pseudodendroides, or any other existing pyrochroine genus.

Two new genera and species of tiger beetles from Baltic amber (Coleoptera: Carabidae: Cicindelinae)
(2017)
Two fossil tiger beetle species (Coleoptera, Carabidae, Cicindelinae) are described from Eocene Baltic amber using light microscopic and X-ray microscopic techniques. Both species are considered representatives of the subtribe Iresina Rivalier, 1971 due to the shared combination of character states: glabrous head, six labral and four suborbital setae, and glabrous pronotum. Palaeopronyssiformia groehni Wiesner, Will, and Schmidt, new genus, new species, is characterized by a glabrous and furrowed head with six labral setae, large eyes, presence of two supraorbital setae on each side, mandibles with two teeth of the incisor region, and a glabrous and furrowed pronotum. Palaeoiresina cassolai Wiesner, Will, and Schmidt, new genus, new species, is characterized by a unicolored, undentated labrum, mandibles with two teeth of the incisor region, glabrous head with six labral setae, two clypeal setae, two supraorbital setae on each side, and a glabrous pronotum, mesepisternum, mesepimeron, and metepisternum. The species described here represent the only known tiger beetle fossils preserved in Baltic amber.

This paper revises the genus Ganelius Benesh, which is endemic to Madagascar, in the stag beetle tribe Figulini Burmeister (Coleoptera: Lucanidae: Lucaninae). Species in the genus are striking in their highly sexually dimorphic mandibles, a character that rarely occurs in the tribe. The genus was previously comprised of four species, but three of these names were problematic or questionably applied. A lectotype is designated for G. madagascariensis Laporte, a neotype is designated for Ganelius oberndorferi Nonfried, and Nigidius passaliformis Benesh is newly synonymized with G. oberndorferi. Two new species, G. gnamptus Paulsen and G. zombi Paulsen, are described from western Madagascar. The identity of the overlooked Ganelius nageli (Kriesche) is fixed through a neotype designation, and the species is moved to the new genus Agnelius, which is distinguished from Ganelius by a lack of sexual dimorphism, serrate protibiae, and a more flattened body.
