The fauna of the bryocorine plant bug tribe Eccritotarsini from India and Sri Lanka is reviewed and updated. Ten genera and 20 species are reported from the region including two genera and six species described as new: Harpedona vittlaensis sp. nov., Lopidolon dandeliensis sp. nov., Mertila rubrocephala sp. nov., Namyatovia gen. nov. for N. castlerockensis gen. et sp. nov. (as the type species) and N. sirsiensis gen. et sp. nov., and Stonedahlia gen. nov. for S. mishmiensis gen. et sp. nov. The genus Bromeliaemiris Schumacher, 1919 is synonymized with Lopidolon Poppius, 1911. Dioclerus lutheri (Poppius, 1912) and Ernestinus ramkeshariae Yasunaga & Ishikawa, 2016 are reported from India for the first time. Differential diagnoses, keys, habitus photographs, illustrations of male genitalic structures, host and distributional information are provided for all genera and species.
F.T. Kützing introduced Cocconeis molesta with only an uninformative description and a poor illustration: C. molesta has small, oblong valves and is an epiphyte. Another species, Cocconeis diaphana, described by William Smith, is said to have larger valves than C. molesta, with frustules that are relatively oblong. Smith described two forms: one with a distinct fascia on its raphe valve (var. β), the other without this feature. A third species, Cocconeis dirupta was described by Gregory, who expressed doubts that it differed from C. diaphana. Finally, Cocconeis molesta var. crucifera Grunow was first introduced in Van Heurck’s Atlas but was subsequently treated by Van Heurck as a synonym of C. molesta. No previous account has examined the type material of these species. In this paper, we undertake that task and examine type slides and raw material in order to discriminate these different taxa. We conclude by recognizing three species: Cocconeis molesta Kütz., C. diaphana W.Sm. and C. dirupta W.Greg. Cocconeis diaphana var. β is considered to be a synonym of C. dirupta and C. molesta var. crucifera is considered to be a synonym of C. molesta. Lectotypes are designated for C. diaphana and C. dirupta.
Los ejemplares tipos de Ectinogonia darwini Waterhouse, 1913 y Psiloptera angulicollis Fairmaire y Germain, 1858 (Coleoptera: Buprestidae), fueron localizados, estudiados y establecidos como holotipo por monotipia y lectotipo, respectivamente. Como las descripciones originales son ambiguas e incompletas, ambas especies son redescritas e ilustradas. Basados en estas nominaciones, y en el examen de ejemplares de Ectinogonia Spinola recolectados en el litoral de las provincias de Chañaral (Región de Atacama) y Antofagasta (Región de Antofagasta), y en la zona andina de la Provincia del Tamarugal (Región de Tarapacá), se describen dos nuevas especies del norte de Chile: E. superba Pineda y Mondaca, nueva especie y E. pruinosa Pineda y Mondaca, nueva especie. Se presentan caracteres diagnósticos, fotografías de los adultos y de los órganos genitales del macho y la hembra, junto a observaciones sobre el hábitat, historia natural, y distribución de los taxones tratados.

The original description of Rivudiva trichobasis Lugo-Ortiz & McCafferty, 1998 is short, with few illustrations. The lack of information resulted in a broad specific diagnosis, with emphasis on the spine-like setae on the antenna. Our hypothesis is that the lack of information resulted in many species being hidden behind R. trichobasis name. We evaluated the species R. coveloae (Traver, 1971) and R. venezuelensis (Traver, 1943) considering the new evidence. After analyzing the paratype of R. trichobasis and records of the species in Brazil, the hidden-species hypothesis was corroborated. Five new species were identified among the published records of R. trichobasis of which four are described here: R. amazona sp. nov. (Roraima State), R. oxum sp. nov. (Rondônia State), R. uiara sp. nov. (Amazonas State), R. naia sp. nov. (Roraima State). The fifth species, Rivudiva sp. X from Maranhão State, could not be described due to the poor conservation of the specimen and is therefore left in open nomenclature. Records from Espírito Santo State (Brazil) and from Paraguay are treated as putative and must be evaluated considering the new evidence. Rivudiva venezuelensis and Rivudiva coveloae are diagnosed and illustrated based on type material. After analyzing these two species, we hypothesize that only R. coveloae likely belongs to the genus Rivudiva. However, information on the nymphal stage is needed to corroborate this hypothesis.
