New World species of the histerid beetle genus Xestipyge Marseul (Coleoptera: Histeridae: Dendrophilinae: Paromalini) are reviewed, and X. skelleyi, new species, is described. A dichotomous key and illustrations are provided as identification means for the now five included species from the Western Hemisphere.
A new genus and six new species of the family Gomphodesmidae from the Udzungwa Mts are described, including Pogoro alopias Rosenmejer & Enghoff sp. nov., Pogoro siren Rosenmejer & Enghoff sp. nov., Pogoropsis prolixopes Rosenmejer & Enghoff gen. et sp. nov., Emphysemastix frampt Olsen & Enghoff sp. nov., Agrophogonus hamulus Olsen & Enghoff sp. nov., and Agrophogonus pusillokiellandi Olsen & Enghoff sp. nov. Emphysemastix dracarys Olsen & Enghoff sp. nov. from Iringa city is described. Descriptive notes are given for Pogoro scharffi Hoffman, 2005, and Agrophogonus mwanihana Hoffmann, 2005. General gomphodesmid gonopod morphology is described and illustrated. A key to Udzungwa gomphodesmids is presented, as well as revised keys to all species of Emphysemastix and Agrophogonus. All gomphodesmid species from the Udzungwa Mts are mapped.
Adults of the Neotropical genera Beltia Jacoby (type species: Beltia nicaraguensis Jacoby) and Colaspoides Laporte (type species: Colaspoides limbata [Olivier]) (Chrysomelidae: Eumolpinae: Eumolpini) are difficult to separate. In this paper, the genus Beltia Jacoby is redefined and diagnosed by features of the pygidium, lateral wings of the prosternum, and metatibiae to distinguish it from Colaspoides and other medium-sized, ovate Eumolpini. Fourteen new species from Costa Rica, Panama, Colombia, Ecuador, and Peru are described and illustrated—Beltia awapita, B. confusa, B. gorgona, B. herreri, B. ledesmae, B. napoensis, B. osa, B. rugosa, B. sanchezae, B. talaga, B. tilarana, B. tisingalita, B. tsachila and B. vacilona. A key and range maps for all species recognized herein are provided. Colaspoides placidula Bechyne, Colaspoides placidula angustomarginata Bechyne, Colaspoides chiriquensis Jacoby, and Colaspoides weyrauchi Bechyne are transferred to Beltia and redescribed. Colaspoides turrialbana Bechyne is synonymized with B. chiriquensis, and Colaspoides chanchamaya Bechyne is synonomized with B. weyrauchi. Morphological similarities with Beltia indicate that Old World Colaspoides also should be removed from Colaspoides s. str.
We review the three species currently placed in the genus Xylopertha Guérin-Méneville, 1845, and describe a new species, Xylopertha elegans sp. nov., from Turkey. We propose the following new synonymy: Xylopertha Guérin-Méneville, 1845 (= Paraxylogenes Damoiseau, 1968); Xylopertha reflexicauda (Lesne, 1937) (= Paraxylogenes pistaciae Damoiseau, 1968). We give details of the sexual dimorphism, and summarise information on the distribution and biology of all species. A key to the species of Xylopertha is provided.
Ichneumonopsis Hardy,1973, a genus of oriental fruit flies, is revised and two new species, I. hancocki sp. nov. (from Peninsular Malaysia) and I. taiwanensis sp. nov. (from Taiwan), are described. A key to the three species of Ichneumonopsis is presented. In northern Thailand larvae of I. burmensis Hardy, 1973 develop in bamboo shoots of Pseudoxytenanthera albociliata (Munro) Nguyen and Dendrocalamus strictus (Roxburgh) Nees (Poaceae), not Melocalamus compactiflorus as previously reported. The recently discovered association of I. burmensis with bamboo substantiates our previous assumption assigning Ichneumonopsis to the primarily bamboo-inhabiting tribe Gastrozonini. Hence, we synonymize Ichneumonopsidini under Gastrozonini (syn. nov.).
A revision of the genus Acentroptera Guérin-Méneville, 1844 (Coleoptera: Chrysomelidae: Cassidinae)
(2014)
The species of the genus Acentroptera Guérin-Méneville, 1844 are revised. Thirteen species are treated as valid and are illustrated. A neotype is designated for A. tessellata Baly. Acentroptera maculata Pic from Brazil and A. rubronotata Pic from Brazil are treated as incertae sedis. Acentroptera bita n. sp. and A. lineata n. sp. both from Panama are described as new. A key to the 13 treated species is presented. Five species appear to be associated with bromeliads (Bromeliaceae).
Conidera Rivalier, 1961 is a well-defined subgenus of tiger beetles (Coleoptera: Cicindelidae) hitherto only known from two species endemic to the island of Luzon. This paper describes the first species from Mindoro, with a doubtful record from Mindanao. Cylindera (Conidera) mindoroana Zettel and Wiesner, new species, differs strongly by an unusual shape of the female’s elytra. A diagnosis for Conidera and a key to the species of this subgenus is presented.
