Hermanella is divided into two subgenera, Hermanella s.s. and Guayakia, n. subgen. Adults of Hermanella (G.) maculipennis (Ulmer), n. comb., and Needhamella ehrhardti (Ulmer), n. comb., and the nymph of Hermanella (H.) thelma Needham and Murphy are redescribed. The subimago of H. (H.) thelma and the nymphs of H. (G.) maculipennis and N. ehrhardti are described for the first time. Three new species, Hermanella (H.) guttata, Hermanella (G.) grandis, and Hylister plaumanni, are described. Hermanella (H.) guttata is described from the nymph and male and female imagines, Hermanella (G.) grandis from the nymph and female imago, and Hylister plaumanni from the nymph and male and female imagines. Eggs of these genera are described and illustrated, and keys to the nymphs and imagines and oiological notes are presented.

This locality is very distant from the localities in southeast Brazil, where the other two known species of Fractipes Bechynĕ were described. Male and female genitalia are described for the first time in this genus, and F. tayrona is compared with holotype photographs of F. rhabdopteroides Bechynĕ and F. secundus Bechynĕ and Springlová de Bechynĕ. Resumen. Se describe Fractipes tayrona especie nueva (Coleoptera: Chrysomelidae: Eumolpinae: Eumolpini) de la costa Caribe de Colombia. La especie fue recolectada en un bosque seco, en un lugar muy lejos del hábitat de los otros dos especies conocidas de Fractipes Bechynĕ, los cuales están conocidas del sureste de Brasil. Se describe los genitales de los machos y hembras por la primera vez en este género, y se compara F. tayrona a las fotos de los holotipos de F. rhabdopteroides Bechynĕ and F....

The record of the species is based on nymphs collected in San Sebastián de Mariquita city, Tolima department, Colombia.

A numeric score is introduced to objectively describe confidence that a field observation of an interaction between a chrysomelid and a plant represents true herbivory. Literature host plant records, if they exist, are given for included chrysomelid taxa.

Flowers, M. Martínez, M. Navarrete. The habitat comprised plantations of rubber, soybean and palms. Adults (Fig. 14) feed on both fruits and the newly emerged rachis of young palms, but larvae were found exclusively on the fruits (L. Maldonado, pers. comm.) and did significant damage (Fig. 15–16). The larva and pupa are free-living, slug-like in shape and light tan in color. <b>Host plant.</b> Arecaceae: <i>Elaeis guineensis</i> Jacq. (Aslam 1965). This is the first record of a cassidine feeding on fruits. Oil palm has been cultivated in Ecuador since 1953, and studied by INIAP since the 1960's (L. Maldonado, pers. comm.). Damage by <i>D. elaeicola</i> causes a 2% reduction in oil extracted from palm fruits, according to some palm oil extractors (Ortega et al. 2006), and a 5-year study is planned to examine the agricultural problem posed by this cassidine species. <b>Seasonality.</b> This species is present year around but is more numerous at the beginning of the rainy season (December) (A.

Nymphs were found in leaf packs in small streams that can be intermittent in the dry season. This species along with Atopophlebia fortunensis are found associated with the accreted terranes of Central America, the Western Andes of Colombia, and the coastal mountains in northwestern Ecuador.

Carludovica Ruiz and Pav. (Cyclanthaceae) is reported as a new plant family and genus host for two species of Spaethiella Barber and Bridwell. Calathea G. Mey (Marantaceae) is reported as the first host record for Aslamidium capense (Herbst) and Calathea lutea Schult. and Calathea majestica (Linden) H. Kenn. are reported as the first host records for Aslamidium semicirculare (Olivier). Immature stages of Demotispa elaeicola (Aslam) are reported for the first time; larvae are external folivores and both larvae and pupae are solitary and lack exuvio-fecal shields. The adults and larvae of D. elaeicola feed by rasping palm fruits, a rare feeding pattern in Cassidinae.
