A description of four new species of fleas (Insecta, Siphonaptera) from Angola, Ethiopia, Papua New Guinea, and Peru

Four new species of fleas are described: Aphropsylla truncata sp. n. (Ethiopia), Ectinorus hirsutus sp. n. (Peru), Rhinolophopsylla traubi sp. n. (Angola), and Thaumapsylla wilsoni sp. n. (Papua New Guinea). Our understanding of the genus Aphropsylla is deficient, therefore a discussion of host/parasite relationships and new records from Uganda are provided. A key is provided for the genus Aphropsylla, while representatives of the other three genera are associated with existing keys to facilitate their identification. The presence of lucodiscs on Apropsylla and other genera is briefly discussed. The occurrence of lucodiscs among representatives of the order Siphonaptera deserves further investigation

Ascodipteron siamense Speiser 1903

Ascodipteron siamense Speiser, 1903 Ascodipteron siamense Speiser, 1903: 121–126. Nomen dubium. Remarks. Speiser described A. siamense from three syntypes, none of which could be located and are presumed lost. The brevity of Speiser’s description, lack of illustrations, and missing type material, renders an identification of A. siamense impossible. The name is therefore considered a nomen dubium.Published as part of Hastriter, Michael W., 2007, A review of Ascodipterinae (Diptera: Streblidae) of the Oriental and Australasian regions with a description of three new species of Ascodipteron Adensamer and a key to the subfamily, pp. 1-32 in Zootaxa 1636 (1) on page 18, DOI: 10.11646/zootaxa.1636.1.1, http://zenodo.org/record/510336

Jobling described <i>A. megastigmatos</i> from a single specimen from <i>Hipposideros caffer guineensis</i> = <i>H. ruber</i>, Ivory Coast. Both Maa (1965a) and Theodor (1968) expressed doubts on the validity of this species suggesting that it was a possible synonym of <i>A. jonesi</i> whose primary type specimen was collected from Sierra Leone on <i>H. abae</i>. In addition, a large series of <i>A. jonesi</i> was collected from <i>H. caffer</i> from Ghana. The characters used by Jobling (1956) to distinguish <i>A. jonesi</i> and <i>A. megastigmatos</i> included the relative position of the post-gena and mesopleuron and the differing position of the humeral callus of each. These characters are variable from specimen to specimen within the same species and the former character is particularly subject to distortion in mounted material. Maa (1965a) never examined the holotype of either species, nor was the holotype of <i>A. mesostigmatos</i> ever examined by Theodor (1968). Since the holotype of <i>A. mesostigmatos</i> is missing and additional topotypic material is unavailable, this species is considered a <i>nomen dubium</i>.</p>Published as part of <i>Hastriter, Michael W., 2007, A review of Ascodipterinae (Diptera: Streblidae) of the Oriental and Australasian regions with a description of three new species of Ascodipteron Adensamer and a key to the subfamily, pp. 1-32 in Zootaxa 1636 (1)</i> on page 29, DOI: 10.11646/zootaxa.1636.1.1, <a href="http://zenodo.org/record/5103367">http://zenodo.org/record/5103367</a&gt

Echidnophaga suricatta (Siphonaptera: Pulicidae), a new species of flea from the Northern Cape Province, South Africa

Echidnophaga suricatta (Pulicidae), a new species of flea collected from the meerkat (Suricata suricatta Schreber, 1776) near Garies (30°22’S, 17°31’E) and Brandvlei (30°27’S, 20°29’E), Northern Cape Province, South Africa, is described. Based on chaetotaxy of the tarsal segments, this new species is most closely related to E. bradyta Jordan & Rothschild, 1906, E. iberica Ribeiro, Lucientes, Osacar & Calvete, 1994, E. macronychia Jordan & Rothschild, 1906, and E. ochotona Li, 1957.

A Study of MLFMA for Large -Scale Scattering Problems

137 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2003.This research is centered in computational electromagnetics with a focus on solving large-scale problems accurately in a timely fashion using first principle physics. Error control of the translation operator in 3-D is shown. A parallel implementation of the multilevel fast multipole algorithm (MLFMA) was studied as far as parallel efficiency and scaling. The large-scale scattering program (LSSP), based on the ScaleME library, was used to solve ultra-large-scale problems including a 200lambda sphere with 20 million unknowns. As these large-scale problems were solved, techniques were developed to accurately estimate the memory requirements. Careful memory management is needed in order to solve these massive problems. The study of MLFMA in large-scale problems revealed significant errors that stemmed from inconsistencies in constants used by different parts of the algorithm. These were fixed to produce the most accurate data possible for large-scale surface scattering problems. Data was calculated on a missile-like target using both high frequency methods and MLFMA. This data was compared and analyzed to determine possible strategies to increase data acquisition speed and accuracy through multiple computation method hybridization.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD

Description of Lentistivalius philippinensis, a new species of flea (Siphonaptera, Pygiosyllomorpha, Stivalidae), and new records of Ascodipterinae (Streblidae) on bats and other small mammals from Luzon, The Philippines

During May 2009 and July 2011, we collected 357 mammals and examined each for ectoparasites. Among the ectoparasites collected, a new species of flea was discovered. This new species, Lentistivalius philippinensis, is described from the male sex only. Two males were recovered from two specimens of the soricid Crocidura grayi Dobson in Municipality Maria Aurora, Aurora Province, Luzon, Philippines. Additional fleas included Thaumapsylla breviceps orientalis Smit, Thaumapsylla longiforceps Traub, and Ischnopsyllus indicus Jordan. Although the latter species is common in Japan and documented in Guam (as well as mainland Southeast Asia) also on Pipistrellus javanicus (Gray), I. indicus represents a new record in the Philippine Islands. The ascodipterinae (Streblidae) Maabella stomalata and Ascodipteron speiserianum Muir collected from Rhinolophus inops K. Andersen and Rhinolophus subrufus K. Andersen, respectively, also represent new host records. A key to the species of the flea genus Lentistivalius Traub is provided
