Nine new species of Hyperaspis from various South American localities are described, illustrated, and compared with previously described taxa. New taxa are: Hyperaspis luciae, H. corcovado, H. divaricata, H. humboldti, H. mimica, H. praecipua, H. unimaculosa, H. drechseli, and H. esmeraldas. Hyperaspis pectoralis Crotch is recognized as a valid species of Hyperaspis and integrated into the existing classification.
The quasi-free scattering reactions 11C(p, 2p) and 10,11,12C(p, pn) have been studied in inverse kinematics at beam energies of 300–400 MeV/u at the R3B-LAND setup. The outgoing proton-proton and protonneutron pairs were detected in coincidence with the reaction fragments in kinematically complete measurements. The efficiency to detect these pairs has been obtained from GEANT4 simulations which were tested using the 12C(p, 2p) and 12C(p, pn) reactions. Experimental cross sections and momentum distributions have been obtained and compared to DWIA calculations based on eikonal theory. The new results reported here are combined with previously published cross sections for quasi-free scattering from oxygen and nitrogen isotopes and together they enable a systematic study of the reduction of singleparticle strength compared to predictions of the shell model over a wide neutron-to-proton asymmetry range. The combined reduction factors show a weak or no dependence on isospin asymmetry, in contrast to the strong dependency reported in nucleon-removal reactions induced by nuclear targets at lower energies. However, the reduction factors for (p, 2p) are found to be ’significantly smaller than for (p, pn) reactions for all investigated nuclei.
Species of Calloeneis Grote (Coleoptera: Coccinellidae) are discussed, and a key to all recognized species is provided. New species described are C. alexandra, C. angelica, C. blanca, C. bennetti, C. bethany, C.brooke, C. francis, C. jacquelin, C. johnnie, C. kara, C. krista, C. leticia, C. lynne, C. robyn, C. marianne, C. myra,C. rosalie, C. roxanne and C. sheri, all authored by Gordon and Hanley.
Twenty new species are described in Pentilia Mulsant (Coleoptera: Coccinellidae: Scymninae: Cryptognathini) by Gordon and González: Pentilia bernadette, P. chelsea, P. dianna, P. elena, P. ernestine, P. estelle, P. kari, P. jasmine, P. jody, P. kendra. P. krystal, P. lora, P. mable, P. muriel, P. nichole, P. nadine. P. paulette, P. rachael, P. sadie and P. traci. A lectotype is here designated for Pentilia egena Mulsant.
Genera of Cryptognathini (Coleoptera: Coccinellidae) are discussed and a key to all recognized genera is provided. Cryptognatha is revised, and species of this genus are keyed. New species, authored by González and Hanley, are Cryptognatha pam, C. kellie, C. hannah, C. whitney, C. karla, C. celia, C. shelia, C. gayle, C. della and C. vicki. The following new synonymies are proposed: Cryptognatha simillima Sicard = Cryptognatha gemellata Mulsant, Cryptognatha fryii Crotch = Cryptognatha pudibunda Mulsant, Cryptognatha bryanti Brèthes = Cryptognatha pudibunda Mulsant. Lectotypes are here designated for Cryptognatha amicta Gorham, C. weisei Brèthes, C. pudibunda Mulsant and C. fryii Crotch.
The Colombian fluted scale (CFS), Crypticerya multicicatrices Kondo & Unruh (Hemiptera: Monophlebidae) is a polyphagous scale insect which affects about 100 species of plants. Between 2010–2013, the species was reported as an invasive pest on the islands of San Andres and Old Providence, Colombian territory in the Caribbean sea.
Currently, populations of the CFS also have increased in the city of Cali, Valle del Cauca State, mainland Colombia, affecting different host plants, especially leguminous trees such as Caesalpinia peltophoroides Benth., Pithecellobium dulce (Roxb.) Benth., P. saman (Jacq.) Benth. (Fabaceae) and mango, Mangifera indica L. (Anacardiaceae). With the aim of searching for natural enemies to control the CFS, field studies were conducted in the city of Cali between February 2013 and October 2014. As a result of this study, two species of lady beetles were found feeding on CFS, i.e., Anovia punica Gordon and Rodolia cardinalis (Mulsant) (Coleoptera: Coccinellidae). This is the first record of R. cardinalis preying on CFS.
The ladybeetle Anovia sp. (Coleoptera: Coccinellidae: Noviini), known as an important natural enemy of the Colombian fluted scale, Crypticeria muticicatrices Kondo and Gullan (Hemiptera: Coccoidea: Monophlebidae) is here identified as A. punica Gordon, 1972, and reported for the first time from Peru. Here we provide information and illustrations of the great variation in color and dorsal patterns of A. punica found in Colombia and Peru.
The first reports of the multicolored Asian lady beetle Harmonia axyridis (Pallas, 1773) (Coleoptera: Coccinellidae) in Colombia appeared in 2011. However, based on museum insect specimens, the introduction of H. axyridis in Colombia occurred in 1989 or earlier, making it the second oldest record of the species in South America after the deliberate releases of the species in Argentina in 1986. Currently in Colombia, H. axyridis is well established and is here recorded from the States of Antioquia, Caldas, Cauca, Cundinamarca, Nariño, Tolima and Valle del Cauca.
Delphastus quinculus Gordon and Diomus seminulus (Mulsant) (Coleoptera: Coccinellidae) are reported for the first time feeding on eggs and first-instar nymphs of Crypticerya multicicatrices Kondo and Unruh (Hemiptera: Monophlebidae). Diagnosis and illustrations are provided for both species. Updated information on their biology, hosts and geographical distribution is also provided.
