A semantically enriched taxonomic revision of Gryonoides Dodd, 1920 (Hymenoptera, Scelionidae), with a review of the hosts of Teleasinae

Teleasinae are commonly collected scelionids that are the only known egg parasitoids of carabid beetles and therefore play a crucial role in shaping carabid populations in natural and agricultural ecosystems. We review the available host information of Teleasinae, report a new host record, and revise Gryonoides Dodd, 1920, a morphologically distinct teleasine genus. We review the generic concept of Gryonoides and provide diagnoses and descriptions of thirteen Gryonoides species and two varieties: G. glabriceps Dodd, 1920, G. pulchellus Dodd, 1920 (= G. doddi Ogloblin, 1967, syn. nov. and G. pulchricornis Ogloblin, 1967, syn. nov.), G. brasiliensis Masner & Mikó, sp. nov., G. flaviclavus Masner & Mikó, sp. nov., G. fuscoclavatus Masner & Mikó, sp. nov., G. garciai Masner & Mikó, sp. nov., G. mexicali Masner & Mikó, sp. nov., G. mirabilicornis Masner & Mikó, sp. nov., G. obtusus Masner & Mikó, sp. nov., G. paraguayensis Masner & Mikó, sp. nov., G. rugosus Masner & Mikó, sp. nov., G. uruguayensis Masner & Mikó, sp. nov. We treat Gryonoides scutellaris Dodd, 1920, as status uncertain. Gryonoides mirabilicornis Masner & Mikó, sp. nov. is the only known teleasine with tyloids on two consecutive flagellomeres, a well-known trait of Sparasionidae. An illustrated identification key to species of Gryonoides, a queryable semantic representation of species descriptions using PhenoScript, and a simple approach for making Darwin Core Archive files in taxonomic revisions accessible are provided.

MOLECULAR CHARACTERIZATION OF ANISAKID NEMATODES HYSTEROTHYLACIUM SPECIES FROM JAPANESE THREADFIN BREAM NEMIPTERUS JAPONICUS (BLOCH, 1791) (PERCIFORMES, NEMIPERIDAE) FROM IRAQI MARINE WATER FISH

The present study provides a new insight into valuable information on the diverse structure of the Anisakid population and discusses the limited species richness in the Nemipterus japonicus (Bloch,1791) (Perciformes, Nemiperidae). The fishing area consists of various locations in the Arabian Gulf (29°58 0 33 00 N48°28 0 20 E). A total of 315 marine fish were examined, (n=287) were infected. Larval stages (n= 763) encysted within the mesenteries peritoneum and viscera of fish organs were isolated, with a prevalence of 91.11% of infection and, the intensity was 2.65. Molecular analysis was carried out on thirty individuals who have examined the morphology and showed some appearance differences, by amplifying internal transcribed spacers ITS and ITS-1 of nuclear rDNA (rDNA) by PCR using the primer sets NC5/NC2 and SS1/NC13R of thirteen DNA products. Evolutionary analyses were conducted in MEGA X. based on the identity percentage in the GenBank database showed that they belong to anisakid nematodes, in particular, they belong to eleven distinct taxa within the Hysterothylacium Ward & Magath, 1917 (Rhabditida, Raphidascarididae) and one identified species H. amoyense (Hsü, 1933) Deardorff & Overstreet, 1980. The current study records eleven species that belong to a genus of Hysterothylacium; some of the alignment of sequences polymorphisms reveals new different individuals of larvae species that may be adopted as new species if their adult stage is detected, and N. japonicus fish considered as a new host record. The current study provides some insights on the systematic taxonomy of these parasites, in addition, it supports similar studies that have been published elsewhere.

New host record and geographical distribution of Nematoda parasitizing Hypophthalmus marginatus Valenciennes (Siluriformes) from the Tocantins River, Brazil

Hypophthalmus marginatus is among the most commercialized fish from the Amazon region, with fish fillets exported to Southeastern Brazil and other countries. In the present study, the H. marginatus analyzed were parasitized by third-stage larvae of Hysterothylacium sp. and Anisakis sp. These nematodes are being reported for the first time in H. marginatus collected from the Tocantins River, representing a new host and geographical records, and expanding knowledge of the hosts of these nematodes in the Neotropical Region. A brief description with original measurements is presented.

Addendum to a minimalist revision of Costa Rican Braconidae: 28 new species and 23 host records

Twenty-nine species are treated, most of which have host caterpillar and food plant records, and all but one are new to science. The first host record for the agathidine genus Amputoearinus is given. Gnathopleura josequesadai Sharkey, sp. nov. is reported as a hyperparasitoid of fly larvae, the first such record for the genus. The following new species are diagnosed primarily using COI barcode data; Sharkey is the authority for all: Agathidinae: Aerophilus davidwagneri, Aerophilus fundacionbandorum, Aerophilus nicklaphami, Lytopylus davidstopaki, Lytopylus davidschindeli; Alysiinae: Gnathopleura josequesadai; Braconinae: Bracon andreamezae, Bracon franklinpaniaguai, Bracon rafagutierrezi, Bracon guillermoblancoi, Bracon oscarmasisi, Bracon pauldimaurai, Bracon shebadimaurae, Sacirema karendimaurae; Cheloninae: Chelonus minorzunigai; Homolobinae: Homolobus stevestroudi; Macrocentrinae: Macrocentrus michaelstroudi; Orgilinae: Stantonia gilbertfuentesi; Rhysipolinae: Rhysipolis stevearonsoni; Rogadinae: Aleiodes kaydodgeae, Aleiodes kerrydresslerae, Aleiodes josesolanoi, Aleiodes juniorporrasi, Aleiodes rocioecheverri, Aleiodes ronaldzunigai, Choreborogas jesseausubeli, Triraphis doncombi, and Yelicones mayrabonillae.

New host record of microhabitat preferences of the Banggai cardinalfish (Pterapogon kauderni) in the introduced habitat in Luwuk waters, Sulawesi

Banggai cardinalfish Pterapogon kauderni is an endemic apogonid fish from Banggai Islands, Central Sulawesi, which is discovered in strong association with black sea urchin (Diadema spp.). These fish also protected themselves from predators associated with sea anemones, hard coral branching, mushroom coral, soft coral, seagrass, and mangrove roots. The Banggai cardinalfish juveniles generally prefer to associate with sea anemones or mushroom corals as microhabitats. However, they are looking for similar microhabitats if they cannot find sea anemones or mushroom coral Heliofungia actiniformis. Microhabitat observation of Banggai cardinalfish was carried out in Luwuk waters, Banggai Regency. The result showed a new host record for juvenile phases of Banggai cardinalfish associated with upside-down jellyfish Cassiopea andromeda as a microhabitat. Further study is needed to represent areas and seasons to get more evidence between the Banggai cardinalfish and jellyfish association concepts.

Parasitylenchus myiophagus n. sp. (Nematoda: Parasitylenchidae), a tylenchid nematode parasite of long-legged flies (Diptera: Dolichopodidae)

A tylenchid nematode parasite of a male long-legged fly, Tachytrechus sanus Osten Sacken (Diptera: Dolichopodidae) from Montana, USA is described as Parasitylenchus myiophagus n. sp. (Nematoda: Parasitylenchidae). The new species is characterized by the presence of an extremely long first generation female and numerous short and wide second generation males and females produced in “enclosed” clusters in the host’s body cavity. Both generation female nematodes are ovoviviparous, with short stylets lacking knobs and simple tails lacking spikes, palps or mucrons. The second generation males have paired, separate spicules, short stylets, and a bursa but no visible gubernaculum. The fly host shows evidence of demasculinization, which is attributed to nematode parasitism. The gonads of the second generation adults are infected with a microsporidium (Microsporidia), which is a new host record for tylenchid nematodes. A tylenchid-infected Baltic amber dolichopodid shows that associations between these two organisms extend back at least to the Eocene.

Helminths and helminth communities of Carassius gibelio (Bloch, 1782) from the Panicheri Reservoir, Aegean Water Basin, Bulgaria

Ecologoparasitological research was done based on the helminths and helminth communities of the Prussian carp (Carassius gibelio (Bloch, 1782)) from the freshwater ecosystem of the Panicheri Reservoir, Aegean Water Basin, Bulgaria. As a result of the examined nine specimens of the Prussian carp, two species of helminths were found: Ligula intestinalis (Linnaeus, 1758), larvae and Pomphorhynchus laevis (Müller, 1776). The dominant structure of the helminth communities was determined. The Panicheri Reservoir is a new habitat in Bulgaria of P. laevis and L. intestinalis from C. gibelio. C. gibelio is a new host record for L. intestinalis in Bulgaria. The two helminth species are core species for the helminth communities of the examined species of the freshwater fish. P. laevis was distinguished with higher prevalence and mean intensity (P%=33.34; MI=1.34) than L. intestinalis (P%=22.23; MI=1.0). The circulatory pathways of the helminth flow were traced.
