A New Species

Haplaxius is a large genus of cixiid planthoppers that is widespread in the New World and economically important due to the role of H. crudus in transmitting palm lethal decline phytoplasmas. A new species of Haplaxius, here described as Haplaxius pocococo sp. n., was discovered during survey work on palms in north-central Costa Rica. Placement in Haplaxius is supported by sequence analysis of the COI and 18S genes relative to congeners and by morphological characters.

AbstractCopris incertus Say, 1835 (Coleoptera: Scarabaeidae: Scarabaeinae: Coprini) has been described as a New World coprophagous scarab distributed from Mexico to Ecuador with large discontinuities in its range between the Yucatán province and Costa Rica. The C. incertus species complex of the Copris minutus (Drury, 1773) species group consists of C. incertus, Copris laeviceps Harold, 1869, and Copris lugubris Boheman, 1858. Based on external morphology and male genitalia, we discovered that multiple species have been classified as C. incertus. Of these species, five are new: Copris amazonicusnew species, Copris brevicornisnew species, Copris davidinew species, Copris moroninew species, and Copris susanaenew species. Herein, we revise the organisation of the C. incertus species complex and propose a new species complex, the C. laeviceps species complex, which includes: C. davidi, Copris igualensis Warner, 1990, and C. laeviceps, formerly included in the C. incertus species complex. We provide an identification key along with species distribution maps, images of habitus, and diagnostic characters.

A New Species

An ongoing survey for planthoppers associated with palms in the Caribbean basin is being conducted with current efforts on the Caribbean lowlands of Costa Rica. In an expedition in June of 2019, a derbid was found on coconut palms in Alajuela province and was determined to be a new species belonging to the genus Anotia. The novel taxon is described and named Anotia firebugia Bahder & Bartlett sp. n. Additionally, molecular barcode data (COI) is provided for the newly described taxon.

The former monotypic genus Armillipora Quate, known only from Costa Rica and Panama, is redescribed, including the type species A. selvica Quate, this time collected on the Caribbean side of Nicaragua, RAAN department, and illustrated based on male morphological characters. The male of a new species, A. suapiensis sp. nov., from Bolivia, La Paz department, is described here and also figured.

A New Species

Morphological characters of well-established taxonomic utility are infrequently examined for their relative phylogenetic consistency. Second only to characters of reproductive anatomy, jaw morphology and dentition commonly are employed as diagnostic characters for hirudiniform leeches, yet these features are highly variable across the group. Patterns of change were investigated for number of jaws and number of denticles per jaw in a phylogenetic context across 17 hirudiniform leeches representing three families. Phylogeny reconstruction employed 16 morphological characters, as well as two nuclear and two mitochondrial loci, and was evaluated with parsimony and likelihood. Rather than constrain the ancestral number of denticles to extant states, this meristic was optimised with squared-change parsimony. The degree to which dentition patterns were explained by phylogenetic relationships was assessed against a null distribution defined by permutation of extant states across terminals. Dentition was found to be non-randomly explained by phylogeny and, thus, corroborative of relationships among hirudiniform leeches as well as of the uniqueness of a new species of Oxyptychus described here from the Peruvian Amazon.

A New Species

Recent survey efforts in the Neotropics have documented a variety of new species of planthoppers associated with palms. Herein, a new species, Herpis soros sp. n., is described from palms in lowland tropical rainforest from Costa Rica. Other species in the genus (H. metcalfi, H. albida, and H. fuscovittata) are evaluated to provide an updated diagnosis of the genus Herpis. The New World Phaciocephalus is examined because two species were described in the genus Herpis with P. fimbriolata being recorded for both Herpis and Phaciocephalus. After examining holotype material for the New World Phaciocephalus, two species were determined to belong to other genera resulting in new combinations Oropuna orba comb. n. and Persis (Anapersis) pallidovenosa comb. n. The synonymy of Syntames with Herpis is reviewed, with S. fuscus moved to Oropuna as Oropuna fusca comb. n. Finally, molecular analysis of the new species based on COI and 18S show strong support for H. soros sp. n. as a distinct clade relative to all other cenchreines available.

A New Species

We describe the new species Norops arenal sp. nov. from Parque Nacional Volcán Arenal, north-central Costa Rica. In external morphology and genetic similarity of the 16S DNA barcode, Norops arenal is most similar to N. altae, N. fortunensis, N. fuscoauratus, N. gruuo, N. kemptoni, N. monteverde, N. pseudokemptoni, and N. tenorioensis. In morphology it shares with these species the following characteristics: (1) short hind limbs; (2) a single elongate prenasal scale; (3) tiny, smooth, often juxtaposed body scales; and (4) a slender habitus, often delicate. Norops arenal differs from these species, among several scalation details, by having a blackish central area in the male dewlap in life and in preservative (vs. no suffusion of black pigment on male dewlap in the other species), and a small red female dewlap in life (vs. dirty white, cream colored, or orange); extremely short hind legs with the tip of fourth toe of the adpressed hind leg reaching only to level of shoulder (vs. usually at least to level of ear in the other species); a short tail with a tail length/SVL ratio of 1.53 in single specimen with complete tail (vs. this ratio >1.6 in the other species); and a tiny size with 41.5 mm in single known adult male and 38.5 mm in single known adult female (vs. SVL of adults usually >42.0 mm). It further differs from N. altae, N. fuscoauratus, N. gruuo, N. pseudokemptoni, and N. tenorioensis by having a unilobed hemipenis (vs. bilobed in these five species).

A new species of Myxia Bahder & Bartlett (Cixiidae: Cixiinae: Oecleini) is established as Myxia baynardi sp. n. collected from native palms in cloud forest habitat in Costa Rica. Placement in the genus Myxia is supported by molecular analysis of the cytochrome c oxidase subunit I (COI) and 18S loci as well as morphological characters. Haplaxius delta (Kramer) was collected along the Caribbean coast as a new country record for Costa Rica. Based on morphological characters observed and molecular analysis of COI and 18S, H. delta is herein moved to the genus Myxia.
