Costarina.
No full text67 pages : illustrations (some color) ; 26 cm. Parts 1 and 2 issued as no. 3730 and no. 3794 of American Museum novitates. Part of the oonopid PBI project. (Acknowledgments)The Costarina faunas of Panama and Colombia are revised. Because Chickering described the sexes from his Panamanian collections separately, several of his names based only on females are placed as junior synonyms of names based only on males: C. humphreyi (Chickering) is newly synonymized with C. recondita (Chickering), as are C. belinda (Chickering) with C. intempina (Chickering), C. rigida (Chickering) with C. abdita (Chickering), C. silvatica (Chickering) with C. dura (Chickering), and C. improvisa (Chickering) with C. seclusa (Chickering). The Costa Rican species C. pittier Platnick and Berniker is newly recorded from Panama. Nine new species are described from Panama (C. sorkini, cerrocol, bocas, chiriqui, clara, fortuna, almirante, dybasi, and tskui), as are 11 from Colombia (C. sasaima, suiza, otun, choco, yotoco, saladito, antonio, anchicaya, gorgona, helechal, and taraira). Previous studies on more northern species are supplemented; newly available collections from Nicaragua reveal the presence there of two new species (C. kilambe and diablo), and locality records are provided for the Costa Rican members of the genus
Sulawesi Bunomys.
No full text313 pages : illustrations (some color), maps ; 26 cm.Two new species of of Bunomys are described, B. karokophilus and B. torajae, both from the west-central mountain region of central Sulawesi. The descriptions are presented within the context of a systematic review of Bunomys in which are provided characteristics of the genus and species (external form, secondary sexual traits, spermatozoa, stomach morphology, skull, dentition, chromosomes); diagnoses, geographic and elevational distributions; sympatric, syntopic, and parapatric distributional relationships; morphological, distributional, and in some cases ecological comparisons among the species; natural histories for certain species derived from field observations; parasites; allocation of generic and specific synonyms; and documentation of subfossils for two of the species. Eight species are recognized; all are nocturnal, terrestrial, and endemic to the island of Sulawesi. Bunomys chrysocomus has been collected from most regions of the island and inhabits both lowland tropical evergreen and montane rain forests (elevational range = 250-2200 m). Bunomys coelestis is endemic to montane forests on Gunung Lompobatang, the high volcano at the southern end of the southwestern peninsula (1829-2500 m). Bunomys prolatus has been reported only from mountain forest on Gunung Tambusisi at the western end of the eastern peninsula (1829 m). Bunomys torajae, n. sp., is described from a small sample collected in montane forest on Gunung Gandangdewata at the southern end of the west-central mountain block (2500-2600 m). Bunomys fratrorum is currently documented only from the northeastern area of the northern peninsula where it occupies habitats in lowland tropical evergreen and montane rain forests (coastal plain to 1982 m). Bunomys andrewsi has been collected primarily in lowland tropical evergreen rain forests in the core of Sulawesi and on the eastern, southeastern, and southwestern peninsula (coastal plain to 1600 m). Bunomys penitus is strictly montane and recorded only from the west-central mountain block and Pegunungan Mekongga on the southeastern peninsula (1285-2287 m). Bunomys karokophilus, n. sp., is currently known only from lowland tropical evergreen rain forest in the northern portion of the west-central mountain block (823-1150 m). Analyses of morphometric traits (cranial and dental measurements) results in a phenetic relationship among the species in which B. chrysocomus, B. coelestis, B. prolatus, and B. torajae, n. sp., form one group characterized by small physical size and small molars, and B. fratrorum, B. andrewsi, B. penitus, and B. karokophilus another group in which larger physical size and heavier molars are the phenetic definers. Whether or not the integrity of this phenetic pattern will withstand testing by analyses of DNA sequences, it remains a convenient arrangement in which to present and define the eight species. The morphological, elevational, and ecological relationships among the four species of Bunomys (B. chrysocomus, B. andrewsi, B. penitus, and B. karokophilus, n. sp.) collected along my transect area in the northern portion of the west-central mountain block (presently known as Lore Lindu National Park) and comparison between them and the elevational distributions of the other murids encountered along the transect are described...
Phylogenetic relationships of mouse opossums (Didelphidae, Marmosa) with a revised subgeneric classification and notes on sympatric diversity. (American Museum novitates, no. 3817)
No full text27 pages : illustrations, map ; 26 cm.To resolve phylogenetic relationships among species of Marmosa we analyzed DNA sequences from one mitochondrial and three nuclear genes for every member of the nominotypical subgenus and from four species of the subgenus Micoureus. As reported in previous studies, the subgenus Marmosa was found to be paraphyletic, whereas Micoureus was recovered as a robustly supported clade. Species currently referred to the subgenus Marmosa form four strongly supported and morphologically diagnosable groups. Based on these results we recognize a total of five subgenera: Marmosa Gray, 1821 (for macrotarsus, murina, tyleriana, and waterhousei); Micoureus Lesson, 1842 (for alstoni, constantiae, demerarae, paraguayana, phaea, and regina); Stegomarmosa Pine, 1972 (for andersoni and lepida); Eomarmosa, new subgenus (for rubra); and Exulomarmosa, new subgenus (for isthmica, mexicana, robinsoni, simonsi, xerophila, and zeledoni). The best-supported hypothesis of relationships among these clades is ((Stegomarmosa (Marmosa + Micoureus)) (Eomarmosa + Exulomarmosa)), and our results additionally resolve many interspecific relationships within each subgenus. These clades have broadly overlapping geographic distributions, especially in western Amazonia, where the arboreal insectivorous-frugivorous niche of Marmosa is apparently partitioned among multiple sympatric congeners

Reductoonops.
No full text75 pages : illustrations (some color) ; 26 cm. Part of the oonopid PBI project. (Acknowledgments)A new genus, Reductoonops, is established for a group of New World soft-bodied oonopine spiders, found from Mexico south to Chile, characterized by reduced size, a flattened clypeus, loss of the posterior median spinnerets, and often by loss of the four posterior eyes. Members of this group resemble those of Stenoonops Simon but lack the clump of short setae found on the dorsal surface of the palpal tarsus of both sexes in that genus, and often have four pairs of deep channels at the sides of the sternum, the most anterior pair of which demarcate a short, trapezoidal, anterior portion of the sternum. A total of 34 new species are described from Mexico (chamela, armeria, niltepec, real, nubes, jabin), Costa Rica (monte, lucha), Costa Rica and Panama (naci), Panama (almirante, escopeta, bayano), Jamaica (ferry), Curaçao (hato), Martinique (diamant), Colombia (marta, sasaima, meta, leticia), Ecuador (tandapi, pichincha, tina, domingo, otonga, palenque, napo, jatun, hedlite, molleturo, celica, yasuni), the Galapagos Islands (pinta), Peru (carpish), and Chile (elqui)
Nests of Lithurgopsis apicalis.
No full text24 pages : illustrations (some color) ; 26 cmThis paper reports on the biology of Lithurgopsis apicalis (Cresson) that were found excavating nests in the dead and dying flower/seed stalks of Agave in southern Arizona. Females normally gain entry to the soft inner tissue of the stalk by seeking out naturally occurring longitudinal cracks in the hard outer surface of the stalk. Once inside they chew branching tunnels through the soft plant tissue, at the end of which are one or more extremely elongate brood cells. The cells were normally found to contain one or more eggs, each in a small empty pocket entirely within the provisions of soft pollen, which completely filled the cell. The attachment of the egg to the provisions is described, as is the egg itself. The first four larval instars remain attached to the provisions while the elongate fifth (final larval) instar is free from the provisions and starts defecating while still eating the food, which gradually intermixes with fecal pellets. Toward the end of defecation, larvae start spinning strands of silk to form cocoons. After finishing spinning, larvae enter diapause, becoming quiescent over a period of more than a week. However, when in diapause, they still react to touch by curling and uncurling their bodies unlike totally quiescent diapausing larvae of most bees. Cocoon structure and function are described. Throughout the paper, aspects of nesting biology of this species are compared with those of other lithurgines. New details concerning the cocoon of Trichothurgus dubius (Sichel) are presented, and ovarian statistics for Lithurgopsis apicalis are appended

Biology of Lithurgus chrysurus.
No full text12 pages : illustrations ; 26 cm.This, the second study of the nesting biology of Lithurgus chrysurus Fonscolombe found at Palmerton, Carbon Co., Pennsylvania, describes its nest construction, provisioning, egg deposition, and larval development. The first study (Rozen, 2013) was based on observations on the late-stage nesting biology in early fall, when these activities were no longer being performed. Comparisons are made with activities of the native Lithurgopsis apicalis (Cresson); in general, the two species have similar, but not identical, nesting biologies. Because Lithurgus chrysurus is an adventive bee native to the Mediterranean regions and is capable of constructing nests in both soft wood as well as firmer wood, it is unclear why it has not expanded its range to any great extent in the New World
