A new feather mite species, Dolichodectes hispanicus sp. n. (Astigmata: Proctophyllodidae), is described from the Melodious Warbler Hippolais polyglotta (Vieillot) (Passeriformes: Acrocephalidae) in Spain. The new species is closest to the type species of the genus, D. edwardsi (Trouessart, 1885) from the Grear Reed-Warbler Acrocephalus arundinaceus (Linnaeus) (Acrocephalidae). Adults of D. hispanicus differ from those of D. edwardsi by dimensional characteristics, in particular, by having shorter aedeagus that does not extend to the anal suckers in males and shorter hysteronotal shield in females. Tritonymphs of D. hispanicus are much more distinctive and differ from those of D. edwardsi by having the prodorsal shield covering all the prodorsum, the hysteronotal shield occupying about three quarters of the hysterosoma, and idiosomal setae h3 being filiform. The morphological description of the new species is augmented by sequence data from the mitochondrial cytochrome c oxidase subunit I gene fragment (COI)., Sergey V.

Achorovermis testisinuosus gen. et sp. n. (Digenea: Aporocotylidae) infects the heart of the smalltooth sawfish, Pristis pectinata Latham (Rhinopristiformes: Pristidae), in the eastern Gulf of Mexico. Specimens of the new genus, along with the other blood flukes that infect batoids are similar by having an inverse U-shaped intestine and a curving testis as well as by lacking tegumental spines. The new genus differs from all of the other blood flukes infecting batoids by having an elongate body (>50 × longer than wide), a testis having >100 curves, and an ovary wholly anterior to the uterus. It differs from Ogawaia glaucostegi Cutmore, Cribb et Yong, 2018, the only other blood fluke infecting a rhinopristiform, by having a body that is >50 × (vs <30 ×) longer than wide, a testis that is >75 × (vs <40 ×) longer than wide and has >100 (vs <70) curves, an ovary wholly anterior to (vs lateral and dorsal to) the seminal vesicle, a uterus wholly posterior to (vs overlapping and lateral to both) the testis and ovary, and a sinuous (vs convoluted) uterus. The new species joins a small group of chondrichthyan blood flukes that lack tegumental spines: O. glaucostegi, Orchispirium heterovitellatum Madhavi et Rao, 1970, Myliobaticola richardheardi Bullard et Jensen, 2008, Electrovermis zappum Warren et Bullard, 2019. Blood flukes infecting batoids are further unique by having a curving testis. That is, the blood flukes infecting species within Selachii are morphologically distinct from those infecting species within the Batoidea (excluding Gymnurahemecus bulbosus Warren et Bullard, 2019). Based on the morphological similarity, we suspect that the new species shares a recent common ancestor with O. glaucostegi. The discovery of the new species brings the total number of chondrichthyan blood flukes to 11 species assigned to nine genera., Micah B. Warren, Micah D. Bakenhaster, Rachel M. Scharer, Gregg R.

A new mite species Schizocoptes daberti sp. n. (Acariformes: Chirodiscidae) from Chrysochloris stuhlmanni Matsche (Afrosoricida: Chrysochloridae) from the Democratic Republic of the Congo is described. It differs from the closely related species S. conjugatus Lawrence, 1944 in both sexes by distance si-si at least twice longer than si-se (vs these distances are subequal in S. conjugatus); in females by setae cp 30-40 µm long (vs about 65 µm long), and in males by the very weakly sclerotised posterior parts of the hysteronotal shield (vs strongly sclerotised), setae d1 situated anterior to the hysteronotal shield (vs at the hysteronotal shield), and by opened coxal fields III (vs closed). An amended generic diagnosis, including description of immature stages, and a key to named species of Schizocoptes Lawrence, 1944 are provided., Andre V. Bochkov., and Obsahuje bibliografii
Carcinopodacarus polymorphus gen. n. et sp. n. (Acariformes: Dermationidae: Dermationinae) is described from the guira cuckoo Guira guira (Gmelin) (Cuculiformes: Cuculidae) in Brazil. The new genus differs from the closest genus, Psittophagoides Fain, 1964, by the following features: in both sexes, the anterior spines of trochanters I and II are absent (vs present in Psittophagoides), setae d2 are distinctly developed (vs only alveoli), and genual setae mGI are absent (vs present); in males, the hysteronotal shield is split transversally at the level of trochanters III (vs hysteronotal shield entire); in females, the platelets situated posterior to the propodonotal shield are absent (vs present), the metapodosomal sclerites are present (vs absent), and the adanal shields are fused anteriorly to each other (vs separated from each other). In this species, andropolymorphism is detected for the first time for the family. It involves various characters but the most impressive feature is the structure of legs III. In hetero- and mesomorphic males, these legs are strongly hypertrophied and have a distinct ventral spur on femora III; in homeomorphic males, legs III are not modified and subequal to legs IV., Fabio Akashi Hernandes, Luiz Gustavo A. Pedroso, Andre V. Bochkov., and Obsahuje bibliografii
A new species, Castosyringophilus meropis sp. n., found in quills of feathers of the European bee-eater Merops apiaster Linnaeus (Coraciiformes: Meropidae) is described. This new species is close to C. claravis Skoracki et Glowska, 2008 and differs, in females, by the presence apunctate coxal fields (vs sparsely punctate in C. claravis) and by the lengths of setae d1 145-180 µm, f2 170-185 µm and ag3 190-215 µm (vs d1 200-220 µm, f2 230-250 µm and ag3 150-170 µm). We present a vast mite material collected from bee-eaters originated from different localities in Europe, Asia and Africa, both breeding and wintering grounds of this bird. It indicates that the whole world population of the European bee-eater is parasitised by this quill mite species., Maciej Skoracki, Martin Hromada, Bozena Sikora., and Obsahuje bibliografii
A new species of Lymanopoda Westwood, a cloud forest Neotropical genus of Satyrinae, is described from the páramo grasslands on an isolated, peripheral massif in the Colombian Central Cordillera of the Andes: L. flammigera Pyrcz, Prieto & Boyer, sp. n. The genus Lymanopoda is species-rich (approx. 65 species) and its alpha taxonomy is relatively well researched. Relationships within the genus using molecular data have also been explored. The new species is outstanding for its golden yellow colour in males, not found in any other neotropical Satyrinae. Cladograms were constructed based on COI sequences of 47 species of Lymanopoda (~ 70% of the known species) including 17 from Colombia. The new species segregates in the "tolima" clade, which comprises four other high altitude Colombian species, as well as two from Ecuador. However, it is the comparative analysis of male genitalia, in particular the superuncus and valvae, which identified its closest relatives, thus confirming that genital characters can help refine molecular phylogenies. In addition to identifying species using mitochondrial DNA (mtDNA barcodes), nucleotide sites with unique fixed states used to identify nine species of Lymanopoda from Colombia are also presented., Tomasz W.

A new species of the genus Lemuralges Fain, 1963 (Acariformes: Psoroptidae: Makialginae) is described from the Malagasy lemur Propithecus diadema (Bennett) (Primates: Indriidae) based on all postembryonic instars. This new species differs from the only known species in this genus, Lemuralges intermedius Fain, 1963, by the following features: both sexes of L. propithecus sp. n. show a pair of medioventral projections of the subcapitulum (vs without projections in L. intermedius) and the propodonotal shield is slightly ornamented (vs unornamented); in males the hysteronotal shield is completely covered by longitudinal striae (vs median part without striae), setae c2 are 120-140 µm long (vs 200-210 µm long), and femur III has a short transverse furrow dorsally (vs a longitudinal furrow); in females, setae h2 are, at least, 2 times shorter than h3 (vs slightly longer, or subequal to, h3), tibia IV has a ventro-apical projection (vs without projection). Larvae and protonymphs of the new species show some unique developmental delays. Female and male tritonymphs differ by their external morphology., Andre V. Bochkov, Hans Klompen, Randall E. Junge, Cathy V. Williams., and Obsahuje bibliografii
The morphology of the male salivary glands of eighteen species of Panorpidae from China was studied using light microscopy. The results show that the male salivary glands differ markedly both at generic and specific levels. In Neopanorpa, the salivary glands consist of only two simple long secretory tubes extending to the fifth or sixth abdominal segment, whereas in Sinopanorpa, the salivary glands are composed of six extremely elongated secretory tubes. In Panorpa, the salivary glands are quite diverse, comprising two simple short secretory tubes only extending to the prothorax in the P. amurensis group (P. liui and P. jilinensis), six long tubes in the P. centralis group, eight to twelve in the P. diceras group and of a very variable number in the P. davidi group (especially in P. bifasciata and P. subambra). Morphology of the male salivary glands should be included in future studies on the systematics and phylogeny of the Panorpidae. and Na Ma, Shu-Yu Liu, Bao-Zhen Hua.
A new genus and new species of Cantacaderinae (Heteroptera: Tingidae) is described, Caledoderus monteithi. A key to genera is provided. The phylogenetic relationships among the Cantacaderinae, including this new genus and species, are revisited. The results are congruent with previous studies. However, the Ceratocaderini is a sister group of Carldrakeaninae and not Cantacaderini, even if only weakly supported by the analysis. Therefore, the status of Ceratocaderini and Cantacaderini is maintained, whereas Carldrakeanini stat. nov. is reduced to tribal level and they are all included in the Cantacaderinae., Eric Guilbert., and Obsahuje seznam literatury
Ruavermis mikebargeri gen. et sp. n. infects the yellow-headed temple turtles Heosemys annandalii (Boulenger et Robinson) in the Mekong River Basin. It resembles Platt Roberts et Bullard, 2018 and Coeuritrema Mehra, 1933 by having the anterior to posterior anatomical sequence of a ventral sucker, external seminal vesicle, cirrus sac, anterior testis, ovary, transverse vitelline duct, and posterior testis. These genera are further similar by having the combination of an elongate/ovoid aspinous body, a ventral sucker at the level of the body constriction, an oesophagus that terminates in the anterior 1/5 of the body and that is ventral to the anterior nerve commissure, intestinal caeca that bifurcate in the anterior 1/3 of the body (not immediately anterior to the ventral sucker), a sinistral caecum that bends toward the midline at level of the cirrus and common genital pore, an external seminal vesicle that abuts the anterodextral margin of the cirrus sac, an oviduct that emerges from the dextral margin of the ovary, and an oviducal seminal receptacle that comprises the middle portion of the oviduct. These genera lack lateral oesophageal diverticulae and a median oesophageal diverticulum. The new genus is unique by having a papillate ventral body surface, an external seminal vesicle lateral to the cirrus sac, vasa efferentia that are ventral to the gonads, an oviduct that is convoluted, a Laurer's canal pore that is preovarian, a Laurer's canal that extends anterolaterad, and an excretory vesicle that is Y-shaped. The 28S rDNA phylogenetic analysis recovered the new species sister to Coeuritrema platti Roberts et Bullard, 2016, with that clade sister to Hapalorhynchus spp. and Platt spp. The new turtle blood fluke is the fourth from Vietnam, second from a Vietnam geomydid, and first from Heosemys Stejneger as well as the first endohelminth from the yellow-headed temple turtle., Haley R.
