A new genus and two new nematode species (Drilonematoidea: Ungellidae: Synoecneminae) parasitic in two morphs of Drawida ghilarovi Gates,endemic earthworm from the Russian Far East

Drasico n. g. is erected to accommodate two new species of nematode, Drasico nemoralis n. sp. and D. paludigenus n. sp., recovered from coelomic cavities of Drawida ghilarovi Gates, endemic earthworms of the Russian Far East. The new genus is characterised by the following unique for the Synoecneminae characters: apical portion of the head attenuated, cephalic hooks displaced to the base of attenuated portion, amphids displaced posterior to cephalic hooks, excretory duct short and weak, males possessing several genital papilliform sensilla. The new species are differentiated by the size, number and disposition of the male genital sensilla (larger and more numerous in D. nemoralis n. sp.); the body shape of females (with thinner neck and wider mid-body in D. paludigenus n. sp.) and the ovarian tube arranged in transversal folds in D. paludigenus (vs longitudinal folds in D. nemoralis n. sp.). Nucleotide sequences of D2–D3 expansion segment of 28S rDNA for the two new species differed at 13 positions. Phylogenetic analysis revealed close relationships of Drasico n. g. with species of Siconema Timm, 1966. The host species was represented by two morphs (blue-grey forest and tar-black meadow-swamp morph) with intraspecific divergence of 16–17% for cytochrome c oxidase subunit 1 (COI) gene, and each host morph was found infected by a different nematode species. A co-infection with the plectid nematode Creagrocercus drawidae Ivanova & Spiridonov, 2011 was recorded together with D. nemoralis n. sp. in the blue-grey forest morph.

Revision of the genus Adorodocia Brenske 1893 (Coleoptera: Scarabaeoidea: Rutelinae: Adoretini) endemic to Madagascar

Summary. The Adoretini of the Malagasy endemic genus Adorodocia Brenske 1893 is revised. Fourteen new species and one new subspecies are described and compared with their most closely related species: A. constricta n. sp., A. cuccodoroi n. sp., A. flava n. sp., A. liliae n. sp., A. marginata n. sp., A. peyrierasi n. sp., A. pseudoconstricta n. sp., A. pseudoflava n. sp., A. pseudostrigata n. sp., A. recta n. sp., A. robusta n. sp., A. sogai n. sp., A. vadoni n. sp., A. viettei n. sp. and A. vittaticollis flavipes n. ssp. The synonymy between Adoretus strigatus Waterhouse 1878, and Pseudadorodocia aenigma Arrow 1901, is confirmed. Thus, based on the results of this study, the genus Adorodocia includes 16 species, and one of them is represented by two subspecies. Diagnostic characters to separate the species in the genus deal mostly with the shape of parameres, color of body and legs, shape of pronotum and female eighth tergite, setation of pronotum and elytra. Key to species, diagnoses and distribution for each species are provided. Endophallus and female genitalia are illustrated for the first time for this genus.

Diversity starts early: notharctid primates from the Sandcouleean (Early Eocene) of the Powder River Basin,Wyoming, USA

Abstract

Abundant specimens, mostly isolated teeth, of the Primate family Notharctidae occur in the Early Eocene rocks of the Powder River Basin of northeastern Wyoming, USA. Very early in the North American history of the family, the notharctid species diversified and this diversity may have been widespread, and not restricted to more southerly areas in the Rocky Mountains. The diversity is shown by detailed analysis of the molar dentition. Two new genera are established: Megaceralemur with Megaceralemur trigonodus as its type and Megaceralemur matthewi sp. nov. as a Sandcouleean species and Pinolophus, with Pinolophus meikei sp. nov. as its type, for a form with an entoconid notch on lower molar 1. Megaceralemur has a prominent nannopithex-fold which dominates the posterior cingulum of upper molars 1–2 and a cristid obliqua on lower molar 1 which attaches to the metaconid, not the metalophid as it does in Cantius and other genera. A small species, Cantius lohseorum sp. nov., is named for a derived lineage the size of Cantius torresi.

Two Anthocoris bugs as predators of glasshouse aphids – voracity and prey preference

Voracity and prey preference were evaluated for adult females of the predatory bugs Anthocoris nemorum (L.) and Anthocoris nemoralis (Fabricius) (Heteroptera: Anthocoridae) preying upon five species of aphids (Homoptera: Aphididae), of which Myzus persicae Sulzer, Aulacorthum solani (Kaltenbach), Macrosiphum euphorbiae (Thomas), and Aphis gossypii Glover are common pests in Danish glasshouse crops. Aphis fabae Scopoli was included to determine the influence of food quality on the preference of the predators, since A. fabae has proved to be of poor nutritional value to Anthocoris spp. The experiments were carried out over 24 h in climate cabinets at 20 °C, 60–70% r.h., L18:D6. The aphids were offered in equal amounts in combinations of two species in instars of comparable size. Myzus persicae served as a reference species in all combinations. Both predators accepted all five species of aphids as prey. The numbers of aphids killed per 24 h period varied between 3.7 and 18.0 for A. nemorum and between 3.6 and 12.7 for A. nemoralis. Field collected A. nemorum females, presumably in a state of reproductive diapause, killed in three of four prey combinations significantly more aphids than did ovipositing A. nemoralis females which originated from a commercial rearing. When A. nemorum females had terminated their reproductive diapause and commenced oviposition, voracity increased approximately threefold. When prey preferences were evaluated as a total number of killed prey, no difference in preference was found between the two Anthocoris species. Both predatory bugs preferred M. persicae to the other species, the most accepted alternative prey were A. gossypii, A. fabae, A. solani, and M. euphorbiae, in descending order. However, evaluating preference by number of aphids consumed, A. nemoralis showed a more pronounced preference for M. persicae, especially when combined with A. fabae. In nearly every case, A. nemoralis rejected A. fabae as a food item after killing the aphid. Thus, A. nemoralis exhibited a more specific food choice than A. nemorum. By killing and consuming different aphid species found in glasshouse crops – particularly M. persicae– both A. nemorum and A. nemoralis showed preliminary qualities as agents for the biological control of aphids.

Six new species of Rhamnocercus Monaco,Wood & Mizelle, 1954 (Monogenea: Diplectanidae) infecting the gills from South American sciaenid fishes

A parasitological survey searching diplectanids (Monogenea: Diplecatnidae) infesting the gills of marine fishes from South America was carried out during the 2019–2020 period. The gills of four sciaenid species, 2 Cheilotrema fasciatum Tschudi, 1 smalleye croaker Nebris microps Cuvier, 2 royal highhat Pareques lanfeari (Barton), and 1 minor stardrum Stellifer minor (Tschudi), were sampled. Six new species of Rhamnocercus Monaco, Wood & Mizelle, 1954 were described: Rhamnocercus chacllae n. sp. and Rhamnocercus chaskae n. sp. from P. lanfeari, Rhamnocercus fasciatus n. sp. from C. fasciatum, Rhamnocercus microps n. sp. from N. microps, and Rhamnocercus rimaci n. sp. and Rhamnocercus tantaleani n. sp. from S. minor. Rhamnocercus chacllae n. sp. can be differentiated from its congeners by its L-shaped male copulatory organ (MCO) and by having an anteromedial slight notch at ventral bar. Rhamnocercus chaskae n. sp. differs from the other species of the genus by its long and straight MCO with bifid distal end and by having haptoral accessory spines at level of ventral bar with quadrifid distal portion. Rhamnocercus fasciatus n. sp. is characterized by possessing a straight and long MCO with truncated distal end, haptoral accessory spines at level of ventral bar with bifid distal portion, dorsal bars with a knob at lateral extremity, and a large vagina with bell-shaped. Rhamnocercus microps n. sp. differs from all congeners mainly by having a short and straight MCO with the distal end of internal tube spatulate and uncovered by external tube. Rhamnocercus rimaci n. sp. is can be distinguished from all other species of Rhamnocercus by having an almost J-shaped MCO with the distal end of external tube slight expanded and the distal end of internal tube narrow and uncovered by external tube. Rhamnocercus tantaleani n. sp. is mainly characterized by its MCO, which is tubular and straight, having the distal end of external tube bifurcated (right branch well-expanded and left branch narrow) and the distal end of internal tube enveloped by left branch of the external tube. This is the first data on the parasites of P. lanfeari, a little known, but popular fish in local markets from Peru. Rhamnocercus microps n. sp. is the first described species of Rhamnocercus in Brazil. The present finding brings to 12, the number of known species of Rhamnocercus. A key to Rhamnocercus species is provided.
