Abstract— The checkered beetle genus Ababa is revised for the first time. Morphological evidence suggests that Thaneroclerinae and Isoclerinae comprise a monophyletic group. Based on the positional relationships between the pronotal projection and the prothoracic intercoxal process the isoclerine genus Ababa Casey is taken out of synonymy with Isoclerus Lewis. Cleridopsis Champion is considered to be a junior synonym of Ababa Casey. On the basis of the tarsal formula, the genus Allothaneroclerus Corporaal, with a tarsal formula of 5-5-5, is removed from Isoclerinae, whose genera show a 5-4-4 tarsal formula, and placed into the subfamily Thaneroclerinae. Ababa specimens were collected in fungi niches and it is postulated that the elongated stomodaeum found in adults serve as a crop to process soft food such as the eggs, larvae, and pupae of fungivorous prey. Ababa comprises A. adona Opitz, new species, A. epiiska Opitz, new species, A. granaria Opitz, new species, A. latimana (Champion), and A. tantilla (LeConte). A lectotype was designated for Ababa latimana (Champion). It is hypothesized that the ancestral stock of Ababa and Parateneroclerus evolved in the mid-Tertiary forests of South America. Included in this work are: A brief discussion about Ababa natural history, a discussion of Ababa phylogeny based on a phylogenetic tree generated by WINCLADA in conjunction with NONA, a Bootstrap consensus tree, a key to Ababa species, 10 scanning electron micrographs, one distribution map, four photographs of the aedeagus, and six color habitus photographs.
Abstract A total of 93 adult male and 1,191 larval caddisflies (Trichoptera), representing 10 taxonomic families, 16 genera and 39 species, were collected from a total of 46 lotic and lentic sites throughout Broome County, New York during 1973–2014. While this checklist is not an exhaustively complete county distributional inventory, it is intended to serve as a baseline compilation for future work.
We characterized the taxonomic richness of epigean coleopterans and assessed the sampling quality in Llullaillaco National Park (Antofagasta Region, Chile). The study was conducted in representative sites of the national park during the years 2017 and 2018. A total of 185 specimens were captured, belonging to 21 species grouped in 19 genera and 10 families. Entomochilus Solier and Praocis Eschscholtz being the only genera with more than one species. The accumulation curves demonstrating that the inventory of epigean coleopteran richness is still incomplete for the sampled area. This work is the first inventory of arthropod species richness in high-Andean ecosystems, but additional samplings in other habitats and seasons are required to expand the inventory of coleopteran fauna for this protected area.
Notes on nesting and gregarious behavior of the blue nest renting wasp Chalybion japonicum (Gribodo) are presented. Three focal nests, freshly attached to the walls of an abandoned house belonging to the mud dauber wasp Sceliphron madraspatanum were occupied by C. japonicum, suggesting that the wasp is a nest invader of S. madraspatanum. Aggregation of C. japonicum males on the string of the sack, which hung loosely beneath the ceiling, undoubtedly plays a role to help males finding females easily rather than by having to take flight. Discussion on relationship of occurrence between C. japonicum and C. bengalense is included. The new appellation "nest renting wasps" for Chalybion species is suggested.
We surveyed apple orchards in the Finger Lakes region of New York State. Pollinator guilds included many honey bees and native bee species known to be effective pollinators of apples. Of the 31 native bee species collected, 14 species belong to eight subgenera of Andrena. Cavity-nesting mason bees were represented by a single female blue orchard bee, Osmia lignaria Say. The most numerous bees were mining bees in the genus Andrena. This paper serves as a preliminary look at the native bee pollinators in apple orchards in New York State.
Papuamorbus rostellus, new genus and new species, is described from Papua New Guinea, and included in the tribe Amorbini. A dorsal view illustration and drawing of male genital capsule are provided. A key to the known genera of Amorbini is given.
Abstract The apparently aposematic immature stages of a tropical shining leaf beetle, Lema insularis, are described, the host plant is revealed to be Dioscorea mexicana, and observations on the camouflaged larvae of a co-existing herbivore, the sawfly Acorduloceridea compressicornis, and the adults of a co-mimic, Diabrotica godmani, are made.
In 2001 Brood VII of the periodical cicada in central New York emerged over a reduced geographic range, as predicted by Pechuman (1985). We found no evidence in Livingston or Cayuga Counties of periodical cicadas emerging in the populations studied by Pechuman during the 1984 emergence, and the majority of the brood is now limited to populations in Onondaga Nation Territory. The decline of Brood VII during the 20th century has occurred in spite of an increase in the total area of potentially suitable habitat across New York and specifically in the counties in which the cicadas were historically present. The observed reduction in range is discussed in terms of a historical spatial bottleneck followed by fragmentation of historically-occupied habitat combined with the poor abilities of these cicadas to disperse to new habitat.
Eight new species of Hygia from Malaysia (Borneo) are described, and included in the tribe Colpurini. The new species are as follows: H. alta from Sarawak, H. borneensis from Sarawak, H. mjobergi from Sarawak and Sabah, H. murudina from Sarawak and Sabah, H. reyesi from Sarawak and Sabah, H. tomokunii from Sarawak and Sabah, H. vantoli from Sabah, and H. webbi from Sarawak. Dorsal view illustrations and drawings of the male genital capsule, and female genital segments are provided.
Blackburnia riparia, new species is described from the summit of Mt. Waialeale, Kauai, Hawaii, incorporated into a phylogenetic analysis of Blackburnia Sharp, and thereby placed as the adelphotaxon to two other allopatric Kauai species, B. lato Liebherr and B. atra Liebherr. The new species occurs in riparian habitats, including vertical rock-faced seeps and algal mats, and is documented to feed on aquatic larvae of Micropsectra Kieffer (Diptera: Chironomidae). Blackburnia elegans (Sharp) adults also occur in streams on Waialeale summit where they were found walking under water on the undersides of large, flat rocks. Based oil documented prey and observed behavior, both species appear to forage under the waterline. The abdominal and elytral anatomy of adult B. riparia and B. elegans is suitable for retention of a subelytral air bubble, suggesting these species respire underwater. Adults and associated larvae of Blackburnia mandibularis Liebherr inhabit moss-mats along falls' margins at Waipoo Falls, Kokee State Park, Kauai, indicating that this species' active life stages also reside in the riparian zone. Attributes of the larval head capsule and mandibles for B. riparia and B. mandibularis are associated with homologous characters expressed in adult anatomy, ontogenetically linking larval and adult head and mouthpart specializations. The various evolutionary origins of riparian habits are examined across Blackburnia. Via one route, occupation of the montane riparian zone has evolved from terrestrial moss-mat habitation, with concomitant evolutionary reduction of adult compound eyes. A second evolutionary route to the riparian zone is based on occupation of open, disturbed or ephemeral habitats, in some cases assisted by adult winged dispersal.
Blackburnia kavanaughi, new species, previously misidentified as Blackburnia asquithi Liebherr, is described from the western portion of the Alakai Plateau, Kauai, Hawaii. The species is placed phylogenetically based on cladistic analysis including all known Hawaiian Blackburnia, supporting membership in the subgenus Metromenus Sharp. The new species is hypothesized to be most closely related to B. debilis (Perkins) of Molokai and B. kuiki Liebherr of East Maui, sharing enhanced pubescence of the antennal pedicel, reduction in number of the dorsal elytral setae, and elongate ventrolateral setae of tarsomere 5. Individuals of all three species reside in deep arboreal moss mats associated with ohia lehua trees (Metrosideros polymorpha: Myrtaceac). Blackburnia debilis, previously known only from the single male holotype collected in 1902, was recollected in 2005 from Uapa summit, Molokai, in arboreal moss on the mesic leeward edge of ohia lehua forest. Discovery of B. kavanaughi on Kauai implies an additional colonization event from Kauai to newer islands during the diversification of Blackburnia, while corroborating the previous general biogeographic pattern of progressive colonization of the Hawaiian Islands by this clade. Phylogenetic placement of B. debilis + B. kuiki as adelphotaxon to B. kavanaughi results in a hypothesized sister-group relationship between sympatric sister species-the epigean B. calathiformis (Sharp) and the troglobitic B. howarthi (Samuelson and Liebherr)-corroborating F. G. Howarth's general hypothesis for the evolution of Hawaiian troglobites.
The morphology of a macropterous form of Anommatocoris China is described for the first time, based on Anommatocoris bolivianits, new species. Scanning micrographs and line art are provided for most aspects of external morphology; comparative illustrations are provided for members of the tingid subfamilies Cantacaderinae and Tinginae. Characters establishing the relationships of the Vianaidinae with other groups of the Miroidea sensu Schuh and Stys, 1991 are analyzed phylogenetically and discussed.
Certain Holoptilini (Reduviidae: Holoptilinae) have long been believed to attract and paralyze ants through secretions released from a sternal structure on the abdomen termed a "trichome." In this study, the trichome for adults of Ptilocnemus lemur is examined in detail, the first time in any Holoptilini. The trichome comprises a median elevation on abdominal sternite 2, a transverse groove, a median projection on sternite 3, and four groups of setae and hair-like projections. The hair-like projections (hairs of group 3 and 4) are shown to be associated with a layer of glandular units, which may be the source of ant-attracting or paralyzing secretions. Apart from these glandular units, a second type of glands is present on the sternum. These so far undocumented glandular units are arranged in distinct areas on the pregenitalic sternites, and are conspicuous by their large pores. Nymphs of P. lemur do not possess a trichome, but the glandular areas on the pregenitalic segments are already present.
