A New Species

Eurystyles comprises about 23 species ranging from Mexico to northern Argentina. Six species are recognized in Mexico and Central America and three in Costa Rica. A new species, named E. uxoris, is here described and illustrated based on Costa Rican material. The species is similar to Eurystyles auriculata and E. standleyi, however, it differs by the smaller plants up to 3 cm tall, smaller leaves of less than 1.6 cm long, flowers with brown dorsal sepal and brown lip apex, petals callose or thickened at apex, and a pandurate lip. Information about distribution, habitat, ecology, etymology and phenology of the newspecies is provided. An updated key to the Costa Rican species of Eurystyles is presented.

A New Species

A new species of bee fly of the genus Chrysanthrax Osten Sacken, C. pennyi, n. sp., is described and illustrated. It was reared from the larva of a myrmeleontid, which marks the first record of parasitism by the genus of that family. The pupal exuvium is described and illustrated and a key to species known from Central America is given.

Twenty-five new species of neotropical Limacodidae, primarily from Central America, are described. The majority of these species (n=15) are from Parasa and Natada generic complexes, both presently known to contain only spiny caterpillars. In the Parasa complex, they include: Parasa figueresi, new species, Parasa joanae, new species, Parasa sandrae, new species, Parasa shirleyae, new species, Euclea mesoamericana, new species, Euclea zurquicola, new species, Euclea microcippus, new species, Euclea costaricana, new species, Euclea gajentaani, new species, Euclea josepsi, new species, Talima beckeri, new species, Talima weissi, new species, and Talima erojasi, new species. In the Natada complex, two new taxa are Natada delgadoi, new species, and Natada varablancana, new species. In a generic complex with hairy caterpillars, the Phobetron complex, six new taxa are: Phobetron guzmanae, new species, Isochaetes dwagsi, new species, Isochaetes kenjii, new species, Isochaetes heevansi, new species, Isochaetes tapantiensis, new species, and Vipsophobetron davisi, new species. In the Prolimacodes and Perola complexes, caterpillars are known to be smooth. New species in the Prolimacodes complex are Prolimacodes montanus, new species, and Dichromapteryx saborioi, new species, while the Perola complex includes Perola aenea, new species, and Epiperola browni, new species. Euclea microcippus, Parasa sandrae and Vipsophobetron davisi are the smallest species known to occur in their genera. Euclea mesoamericana and Parasa figueresi are relatively common in collections but have been mistakenly grouped with Euclea cippus (Cramer) and Parasa schausi Dyar, respectively. Each was reported from both Central and South America, but is now considered to be limited to South America. Talima weissi is closely related to the Mexican species T. assimilis (Dyar), sharing both a detachable clump of hairs on 8 th abdominal segment in males and large ductus seminalis, which hold the hairs, in females. Larval descriptions or hostplants are presented for P. sandrae, P. joanae, E. mesoamericana, E. gajentaani, T. beckeri, T. weissi, I. dwagsi, I. kenjii, I. heevansi, and V. davisi. Euclea zurquicola, E. josepsi, T. erojasi, N. delgadoi, N. varablancana, P. guzmanae, I. tapantiensis, and E. browni are known from only one locality, each in Costa Rica, while the last four are known only from unique specimens.

A new species of pseudothelphusid crab, Allacanthos yawi n. sp., from the Río Volcán drainage, Puntarenas Province, southern Costa Rica, Central America, is described and illustrated. This is the second species to be assigned to the genus Allacanthos Smalley, 1964. The new species is distinguished by its congener by having a first gonopod with a mesiolaterally flattened distal portion, a concave and nearly smooth subdistal portion of the lateral and cephalic sides, a narrow marginal process with a nearly straight distal border, and a lateral lobe with a sharp tip on the apex. An amended diagnosis for Allacanthos is provided.

A New Species

Bothriomyrmex paradoxus Dubovikov and Longino sp. nov. is described from Costa Rica, based on two collections from widely separated localities. These are the first collections of the genus Bothriomyrmex in the Americas. The genus Bothriomyrmex can be divided into Palearctic species (Both- riomyrmex s.s.) and Oriental and Australian species, based on differences in palp formula and queen wing venation. Bothriomyrmex paradoxus shares palp and wing characters with the Palearctic species. It is probably native to Central America and long separated from its Old World relatives.

A New Species

Dussia atropurpurea is a new species found in Costa Rica and Panamá. It differs from all other Dussia species in this region in its dark purple sarcotesta. The only other species of Dussia with a sarcotesta of this colour is the Amazonian D. tessmannii which is clearly distinct morphologically. Sarcotesta colour is an important character for species delimitation in Dussia, but is infrequently recorded.

A New Species

New taxa of the family Ropalomeridae from Costa Rica are described, and additional records of ropalomerid flies fromMexico and Central America are provided. The new genus and species Acrocephalomyia zumbadoi can be easily distin-guished from all other ropalomerid genera by the following combination of characters: angular forward projection of head,absence of ocelli, flat face, bare arista, long scutum, and scutellum triangular-shaped and dorsally flattened with only onepair of apical bristles with bases approximated. The new species Ropalomera aterrima can be recognized from congenersby remarkable differences of the head, the shape of the scutellum, the absence of scutal vittae, fumose wings, and by theblack coloration of the body, ocellar bristles large, one postpronotal bristle, scutum without pollinose vittae and flat scutellum. Lenkokroeberia chryserea Prado and Kroeberia fuliginosa Lindner are newly confirmed for Costa Rica.

A New Species

A new species, Macrobiotus huziori sp. nov. is described from moss samples collected in Costa Rica (Central America). The eggs of the new species have a unique, never described before, type of multi-level areolation which makes M. huziori sp. nov. easily distinguishable from all the known species. We also provide SEM pictures revealing the complex structure of the granulation on the legs (each granule consists of many smaller cones/granules).

A New Species

A redescription of Pagurus albus (Benedict, 1892) is presented together with a description of a new species of hermit crab, Pagurus pseudoalbus sp. n., from the Pacific coast of Costa Rica. Pagurus pseudoalbus sp. n. differs from P. albus and P. perlatus by the length of antennal acicles, which do not exceed the distal margin of the 4th antennal segment, whereas in the latter two species, the antennal acicles exceed the 4th antennal segment; the antennular peduncle is proportionally longer than the ocular peduncle in the new species compared to P. perlatus, but shorter than in P. albus; the palm of the right cheliped in P. pseudoalbus sp. n. is 1.3 times as long as broad, while in P. albus and P. perlatus it is 1.0 and 1.4 times as long as broad, respectively. Including the new species, the genus Pagurus in the Eastern Tropical Pacific currently includes 16 species.

A New Species

The genus Neophyllaphis (Takahashi) (Aphididae: Neophyllaphidinae) is composed of 18 species; however, in the Americas only nine species have been reported previously. A new species, Neophyllaphisvaricolor Miller & Halbert, was described in 2014 in USA. Colonies resembling those of this new species have been observed in Costa Rica on Podocarpus spp. In order to determine if N.varicolor is also present in Costa Rica, we sampled Neophyllaphis colonies from Podocarpusfalcatus and P.chinensis. Additionally, we sampled individuals from Podocarpus sp. in Spain and Vietnam. DNA of each sample was extracted and used to amplify and sequence the cytochrome c oxidase subunit I (COI) and elongation factor I (EF-1α) partial regions. According to morphological characteristics, sequences comparisons done in GenBank and BOLD, and phylogenetic analyses, the colonies collected from Podocarpus spp. in Costa Rica and the colony from Vietnam corresponded to the species N.varicolor. To the best of our knowledge this is the first report of the presence of N.varicolor in Central America and Vietnam.
