Scarab Beetles

Two new endemic species of scarab beetles are described from Costa Rica, Onthophagus humboldtisp. nov. and Uroxys bonplandisp. nov.Onthophagus humboldtisp. nov. is also the tenth brachypterous Onthophagus species to be described worldwide, representing also a case of extreme brachyptery in Onthophagini. Illustrations for both new species, as well as marking differences with closely related species are included. Maps showing the distribution of the new species, as well as the distribution of brachypterous and endemic scarab-beetle species for Costa Rica are presented and discussed. The Cordillera de Talamanca represents an area where Scarabaeinae (four genera) show very high known levels of brachypterism in Mesoamerica. A reconstruction of the montane environment in the Cordillera de Talamanca during the Last Glacial Maximum (~24 ka) is analyzed, in order to try to understand a possible historical biogeography model that might promote high levels of brachypterism in scarab-beetles. The present study supports previous proposals that brachyptery is correlated with stable environments associated with deeply incised valleys. Tropical mountain ranges are also identified as having more endemics than lowland rain forests, contradicting accepted wisdom. Lastly, a mitochondrial DNA analysis supports the existence of the Onthophagus dicranius and the O. clypeatus species-groups as two well-defined and closely related branches.

Se describe una especie nueva de lagartija del grupo de Norops fuscoauratus de Talamanca, Costa Rica. Difiere de las especies emparentadas de Costa Rica (Norops attae) y Panamá (Norops exsul, N. fortunensis y N. kemptoni) básicamente porque una estructura masculina ("dewlap") se extiende hasta el nivel de la axila y por ser rosado con un margen exterior anaranjado. También tiene patas más largas que N. fortunensis y N. kemptoni; difiere de este último y de N. attae y N. exsut en que tiene 2-4 filas ligeramente agrandadas de escamas medio-dorsales La especie nueva solo se conoce de Cerro Pando (frontera entre Costa Rica y Panamá).

The Neotropical geometrine genus Oospila Warren, 1897 includes seventy-nine species and was revised by Cook & Scoble (1995). The genus is distinctive in having a row of raised abdominal crests, which are composed of specialized, erect, metallic shining scales. This paper focuses on the integrative morphological and molecular delimitation of the smallest Oospila species. The wing patterns and genitalia structures of males and females are illustrated. Cook & Scoble (1995) distinguished 13 species groups within Oospila. We discuss the species of the Oospila flavilimes species group, the O. stigma species group and O. miccularia species group below, and separate the O. arpata species complex into a group of its own. Nine new species and two new subspecies are described in this paper: O. cristae sp. n. from Ecuador, O. falcata sp. n. from French Guiana, O. pallidaria boliviensis subsp. n. from Bolivia, and O. loreenae sp. n. from Bolivia (flavilimes species group), O. ehakernae sp. n. from Costa Rica, O. similiplaga bolarpata subsp. n. from Bolivia (arpata species group), O. brehmi sp. n. and O. bifida sp. n. both from Bolivia, O. moseri sp. n. from Brazil, O. absaloni sp. n. and O. pipa sp. n. both from Ecuador (miccularia species group). Oospila similiplaga (Warren) (stat. nov.) is raised here from synonymy with O. arpata (Schaus) and O. imula (Dognin) from synonymy with O. miccularia (Guenée), respectively. Oospila agnetaforslundae nom. nov. is proposed as a replacement name for Oospila marginata Schaus, 1912 (nec Oospila marginata Warren, 1897), raising it to species rank from synonymy of Oospila permagna (Warren, 1909). With this paper, the number of Neotropical Oospila species is raised to 88.

SUMMARYKudoid parasites are significant pathogens of marine fish. In the past, specific identification has been difficult due to a paucity of detailed morphological and biological information provided in the original description of some species. However, the introduction of DNA analysis has dramatically improved diagnosis. For morphological characterization, this paper proposes a new set of schematics including additional measurements to give a more thorough description of spore morphology, and provides evidence for uniqueness of 4 new species: Kudoa gunterae n. sp. (from 10 pomacentrid species and 1 apogonid species), K. kenti n. sp. (from 4 pomacentrid species), K. paraquadricornis n. sp. (from 4 carangid species), and K. whippsi n. sp. (from 8 pomacentrid species and 1 apogonid species). Subtle morphological differences found between closely related species were reflected in their genetics, with increased resolution provided by the large subunit, compared with that of the small subunit, of the ribosomal DNA gene region. This article proposes comprehensive requirements for species descriptions within the Kudoidae that incorporate biology, morphology, and genetic sequence.

Two species of Monstera, apparently endemic to Costa Rica, are newly described and illustrated. Monstera juliusii occurs in the southern Costa Rican portion of the Cordillera de Talamanca at 1600–2250 m, and has been confused with M. standleyana in herbaria. Monstera monteverdensis occurs in the Guanacaste and Tilarán cordilleras, and the northwestern part of the Cordillera Central, at 500–2300 m, and has been confused with M. epipremnoides, M. lentii and M. lechleriana in herbaria. Phenology and suggested conservation categories according to the IUCN Red List criteria are indicated for both new taxa.

AbstractIndividuals of Perilissus nudus sp.nov. of the Perilissus anatinus species group are described. This species, which occurs in the mountain ranges of southern Mexico and Costa Rica, is compared with the closely related species P. anatinus Barron. Locality data on additional specimens of P. anatinus, found in mountain ranges in Mexico, are included. Study of characteristics of P. nudus in relation to P. anatinus clarifies further the relationship of this species group with the other species groups of Perilissus.

Montane Rainforest

A new species of Craugastor (Anura: Craugastoridae) from the montane rainforest of the Cordillera de Talamanca, Costa Rica. A new dirt frog of the Craugastor podiciferus Species Group is described from Costa Rica; it is restricted to elevations between 2330 and 2700 m a.s.l. in the montane rainforest of the Cordillera de Talamanca. Analysis of DNA sequences of the mitochondrial 16S rRNA (16S) and cytochrome oxidase I (COI) genes reveals a distinct lineage within the C. podiciferus Species Group. Additional morphological and morphometric analyses support the distinctiveness of this lineage that is described as a new species herein. The species is distinguished from other members of the C. podiciferus Species Group by its unique coloration: a violet-brown to blackish brown venter with white pigment forming blotches, and dark brown palmar surfaces with prominent white folds between subarticular tubercles in the adults. The genetic divergence of the species from other members of the C. podiciferus Species Group is signifcant (higher than 9.2% in 16S and 13.3% in COI). Although not closely related, it resembles C. podiciferus morphologically, a species that also inhabits montane rainforest. The discovery of this new species highlights the importance of montane rainforest as a center of species richness and endemism.

We describe five new species of lungless salamanders (Plethodontidae) from high mountain habitats along the border betweenCosta Rica and Panama: Bolitoglossa splendida, Bolitoglossa aureogularis, Bolitoglossa kamuk, Nototriton matama, andOedipina nimaso. We also present phylogenetic hypotheses for the new taxa (with the exception of the Oedipina) and their rel-atives based on mitochondrial DNA sequence data. The new species were discovered on a series of expeditions to remote areas (primarily over 1000 m elevation) of the Cordillera de Talamanca, Costa Rica.
