A New Species ofParamacrochiron(Copepoda: Cyclopoida: Macrochironidae) Associated with the Rhizostome MedusaRhopilema hispidumCollected from the Gulf of Thailand, with a Phylogenetic Analysis of the Family Macrochironidae

Abstract During a parasitological survey of fishes at Iguazu National Park, Argentina, specimens belonging to the allocreadiid genus Auriculostoma were collected from the intestine of Characidium heirmostigmata. The erection of the new species is based on a unique combination of morphological traits as well as on phylogenetic analysis. Auriculostoma guacurarii n. sp. resembles four congeneric species – Auriculostoma diagonale, Auriculostoma platense, Auriculostoma tica and Auriculostoma totonacapanensis – in having smooth and oblique testes, but can be distinguished by a combination of several morphological features, hosts association and geographic distribution. Morphologically, the new species can be distinguished from both A. diagonale and A. platense by the egg size (bigger in the first and smaller in the last); from A. tica by a shorter body length, the genital pore position and the extension of the caeca; and from A. totonacapanensis by the size of the oral and ventral sucker and the post-testicular space. Additionally, one specimen of Auriculostoma cf. stenopteri from the characid Charax stenopterus (Characiformes) from La Plata River, Argentina, was sampled and the partial 28S rRNA gene was sequenced. The phylogenetic analysis revealed that A. guacurarii n. sp. clustered with A. tica and these two as sister taxa to A. cf. stenopteri. The new species described herein is the tenth species in the genus and the first one parasitizing a member of the family Crenuchidae.

A New Species

A new species of the continental shelf hyperbenthic genus Pilarella is described, the first from the Indo-Pacific. This is the second species of Pilarella known, and the first description of a male in the genus. The new species is easily distinguished from other species of Pilarella (P. longicornis) based on: (1) short caudal rami, approximately 1.5 times longer than wide; (2) 2 setae on the mandibular endopod; (3) 6 setae on the maxillular coxal epipodite; and (4) in the female, a short left antennule reaching the posterior border of the genital double-somite. The new diagnosis of Pilarella differs from Metacalanus in the separation of ancestral segments IX–XII and XIV–XV of the antennule, and the presence of 5–6 setae on the maxillular praecoxal arthrite. Pilarella is also separated from Metacalanalis based on the absence of a seta on the third ancestral segment of the antennary exopod, the symmetry of legs 1–3, the presence of a medial basal seta on the female leg 5, and 2 lateral exopodal spines on the female leg 5. A molecular phylogenetic analysis of some representative genera of the family Arietellidae, including the present new species, recovers two arietellid clades (Metacalanus- and Arietellus-clades) as in previous studies. Dichotomous keys for the genera of Arietellidae and the species of Pilarella are included.

A New Species

A new species of glomeridellid millipede is described from Guizhou Province, southern China: Tonkinomeris huzhengkunisp. nov. This new epigean species differs very clearly in many structural details, being sufficiently distinct morphologically and disjunct geographically from T. napoensis Nguyen, Sierwald & Marek, 2019, the type and sole species of Tonkinomeris Nguyen, Sierwald & Marek, 2019, which was described recently from northern Vietnam. The genus Tonkinomeris is formally relegated from Glomeridae and assigned to the family Glomeridellidae, which has hitherto been considered strictly Euro-Mediterranean in distribution and is thus new to the diplopod faunas of China and Indochina. Tonkinomeris is re-diagnosed and shown to have perhaps the basalmost position in the family Glomeridellidae. Its relationships are discussed, both morphological and zoogeographical, within and outside the Glomeridellidae, which can now be considered as relict and basically Oriental in origin. Because of the still highly limited array of DNA-barcoding sequences of the COI mitochondrial gene available in the GenBank, the first molecular phylogenetic analysis of Glomerida attempted here shows our phylogram to be too deficient to consider meaningful.

A phylogenetic analysis of the Mycetophiliformia (= Sciaroidea) was performed to determine the relationships among its families and to place the following genera of uncertain position in the system: Heterotricha, Ohakunea, Colonomyia, Freemanomyia, Rhynchoheterotricha, Chiletricha, Afrotricha, Anisotricha, Kenyatricha, Nepaletricha, Sciarosoma, Sciaropota, Insulatricha, Cabamofa, Rogambara, and Starkomyia. Eratomyia n. gen. is described based on a new species from Ecuador. Colonomyia brasiliana sp.n. and Colonomyia freemani sp.n. are described respectively from southern Brazil and Chile. The male of Cabamofa mira Jaschhof is described for the first time. A total of 64 terminal taxa and 137 transformation series (with 202 characters) were included in the data matrix, with a number of new features from thoracic morphology. Willi Hennig’s 1973 system for the higher Bibionomorpha was adopted using the name Mycetophiliformia for the Sciaroidea. The Mycetophiliformia are monophyletic. The family Cecidomyiidae appears as the sister group of the remaining Mycetophiliformia, followed by the Sciaridae. In the preferred topology, the Rangomaramidae appear as the group sister of a clade consisting of (Ditomyiidae + Bolitophilidae + Diadocidiidae + Keroplatidae) and of (Lygistorrhinidae + Mycetophilidae). The topology within the Rangomaramidae is (Chiletrichinae subfam. n. (Heterotrichinae subfam. n. ((Rangomaraminae + Ohakuneinae subfam. n.))). The Chiletrichinae include the genera Kenyatricha, Rhynchoheterotricha, Insulatricha, Chiletricha, and Eratomyia n. gen. Heterotrichinae and Rangomaraminae are monotypic. The subfamily Ohakuneinae includes Ohakunea, Colonomyia, Cabamofa, and Rogambara. The positions of Freemanomyia, Loicia, Taxicnemis, Sciaropota, Starkomyia, Anisotricha, Nepaletricha, and Sciarosoma are considered. Afrotricha might belong to the Sciaridae. The similarities used by many authors to gather the Sciaridae and Mycetophilidae in a clade are shown to be a combination of plesiomorphies and homoplasies.

AbstractElixia cretica T. Sprib. & Lumbsch is described as a new species from the mountains of western Crete. The second member of the previously monotypic genus and only the third member of the family Elixiaceae, it is distinguished by its surficial thallus, larger ascospores and corticolous habit. Molecular phylogenetic analysis based on a sequence of mitochondrial small subunit DNA confirms the position of the new species. We also report E. flexella from New Hampshire (USA) as new to eastern North America.

Holothurians of the family Psychropotidae are widely distributed, but remain least studied deep-sea holothurians. On an expedition in the Western Pacific, six psychropotid specimens were collected by the Jiaolong human operated vehicle (HOV). Through morphological examination, four of them were identified as a new species, Benthodytes jiaolongi sp. nov., which was characterized as having minute papillae, narrow brims, and terminal anus; the ossicles were either rods or primary crosses. The remaining two specimens were identified as Psychropotes verrucicaudatus Xiao, Gong, Kou & Li, 2019, which was first recorded at the Kyushu-Palau Ridge. The phylogenetic analysis confirmed the classification status of B. jiaolongi and P. verrucicaudatus, and indicated a paraphyletic relationship within the genus Benthodytes. The new species clustered with Benthodytes sanguinolenta and was separated from the clade containing the other Benthodytes species.

Abstract This study describes Henneguya sacacaensis n. sp. in specimens of the Osteichthyes Satanoperca jurupari (Heckel, 1840), collected in the Rio Curiaú Environmental Protection Area in the city of Macapá, state of Amapá Brazil. Using optical microscopy and molecular analysis, these cyst-shaped parasites were analyzed. The gills of 57.14% of the analyzed S. jurupari contained hundreds of spores. The cysts found on the gill lamellae were oval-shaped and whitish. The Henneguya spores had an average length of 46.5 (41.3-56.92) µm. The fusiform body of the Henneguya measured 16.5 (13.16-20.01) µm long and 5.1 (3.91-6.12) µm in width, the two polar capsules had a taper of 3.83 (3.4-4.32) µm and a width of 1.68 (1.4-1.99) µm, and the tail measured 30 (22.47-41.67) µm in length, containing a polar filament coiled seven to nine times. Morphogical and phylogenetic analysis allowed the preposition of a new species, Henneguya sacacaensis n. sp, that belongs to the family Myxobolidae and the genus Henneguya.
