The genus chiton Loricella is revised. It comprises nine species. Two of these species, L. neoguinensis n. sp. and L. solomonensis n. sp., are described as new. Based on the analysis of morphological features studied using a scanning electron microscope, a revised diagnosis of the genus is provided. The characters diagnostic for this that distinguish it from the related genus Squamophora are as follows: a tubular hollow inside the dorsal scales, bristles on the dorsal side of the girdle, a wide ventral mouth region, a narrow mantle fold covered with simple longitudinally ribbed scales, smooth ventral scales, pits arranged in longitudinal rows in the central area of the tegmentum, and a bicuspid head of the major lateral teeth of the radula.

Stalked Crinoids

Two new species of deep-sea stalked crinoids belonging to the family Hyocrinidae were collected in the northeastern Pacific. The descriptions contain detailed information on character variations and ontogeny. The five specimens of Gephyrocrinus messingi n. sp. lived at depths ranging from 1,777 m to 2,110 m off British Columbia and California. This new species is the first record of the genus Gephyrocrinus in the Pacific Ocean, which was previously known from only a single species, G. grimaldii, from the northeastern Atlantic at the same depth range. The two species illustrate opposing phenotypes within the same genus. Fifty-eight specimens of the second new species, Ptilocrinus clarki n. sp., were dredged off British Columbia close to the type-locality of P. pinnatus, the type species of the genus Ptilocrinus, but at shallower depths ranging from 1,178 to 1,986 m. This exceptional collection provides significant data on intraspecific variation in the main morphological characters, especially arm pattern. The ontogeny of stalk articulations and the main traits of adoral plate differentiation are described in detail. A complementary investigation on P. pinnatus was conducted using specimens collected by the “Albatross” expedition at a depth of 2,906 m. Despite similarities in external morphology, tegmen and cover plates, the two ptilocrinid species display significant differences in pinnule architecture, aboral cup and stalk articulations. From comparison with Gephyrocrinus messingi n. sp. and Ptilocrinus clarki n. sp., G. grimaldii and P. pinnatus are interpreted as the result of heterochronic development by paedomorphy after ecological or geographic isolation. Pinnule architecture in the two new species suggests first steps in an evolutionary trend toward a rigid box which protects gonad inflation in the proximal part of the pinnule. These new data on Ptilocrinus and Gephyrocrinus create problems in the current taxonomy of the family Hyocrinidae. The main derived characters, especially in pinnule and arm pattern, are used to propose new hypotheses for hyocrinid phylogeny.

This paper deals with some new material of Iranian harvestmen accumulated during and after 2017. These recent collections yielded 11 species from six families, including five species that had previously been known from Iran, and two families and six species which are established as being new for the fauna of the country. The latter include two newly described species of Phalangiidae, namely Homolophus airyamani spec. nov. (male; Hormozgan Province, southern Iran) and Phalangium martensi spec. nov. (male; Khuzestan Province, southwestern Iran). With the study of new specimens and the recording of previously known material, 28 species from six families of Opiliones are currently known from Iranian territories. The records include one species of Biantidae, one species of Dicranolasmatidae, five species of Nemastomatidae, 19 species of Phalangiidae, and a single species each for Sclerosomatidae and Trogulidae.

Abstract The male genitalic characters of Hexapoda are well known for their great taxonomic and systematic value. Despite insect male genitalia displaying large diversity, variation, and modification across orders, some structures are consistently present, and such characters can serve as the basis for discussion regarding homology. In the order Lepidoptera, a male genitalic structure widely known as the ‘juxta’ is present in many taxa and absence or modification of this character can be phylogenetically informative at the generic or higher level. We here focus on the systematics of the so-called ‘Taygetis clade’ within the nymphalid subtribe Euptychiina, and report an unusual case of ‘juxta loss’ in a single species, Taygetina accacioi Nakahara & Freitas, n. sp., a new species from Brazil named and described herein. Additionally, we describe another west Amazonian Taygetina Forster, 1964 species, namely Taygetina brocki Lamas & Nakahara, n. sp., in order to better document the species diversity of Taygetina. Our most up-to-date comprehensive molecular phylogeny regarding ‘Taygetis clade’ recovered these two species as members of a monophyletic Taygetina, reinforcing the absence of juxta being a character state change occurring in a single lineage, resulting in an apomorphic condition, which we report here as a rare case in butterflies (Papilionoidea).

Two new species, Anafroptilum orthostylus sp. n. and Anafroptilum odontostylus sp. n. are described from Thailand based on imagoes reared from larvae. Both new species lack hind wings; larvae of both species have an unusual prominent spine near cercus apex; other characters, especially shape of male imaginal gonostyli and shape of larval tergalii, are quite diverse in these two species. The genus Anafroptilum, hitherto known from the East Palaearctic [as a single species A. kazlauskasi (Kluge 1983)] and from Nearctic [as eight species reported by Jacobus & Wiersema (2014)], is reported from Oriental Region for the first time.

The first verified records of Rhynchelmis from the southeastern Nearctic represent two new species. Both belong to R. (Rhynchelmoides) (Hrabě) n. comb., which is defined here. Rhynchelmis bolinensis n. sp. resembles other R. (Rhynchelmoides) species with elongate spermathecae, but differs in details of the reproductive structures. Rhynchelmis croatanensis n. sp. is similar in many respects, but the gonads and male and female pores are shifted anteriad by one segment, a character previously unknown within the genus. Pararhynchelmis murdocki n. gen., n. sp. has the spermathecal pores in VIII and IX and male pores in X, and the spermathecae connect to the gut. These characters associate the new species with Rhynchelmis, but the combination of differences in morphology or arrangement of atria, spermathecae, blood vessels and nephridia, and the absence of a proboscis, suggest that it be placed in a related genus. Rhynchelmis bolinensis was collected at several sites in North Carolina, but the other two species are known only from single localities.

Two new Dactylellina (nematode-trapping fungi) species, D. yushanensis and D. cangshanensis from the burned forest soil in Cangshan Mountain, Yunnan Province, China are introduced in this paper based on morphology and phylogenetic analysis. Their descriptions and illustrations are provided. Dactylellina yushanensis is characterized by its geniculate branched conidiophore, two types conidia and fusiform, clavate or drop-shaped microconidia grown in conidiophore or produced by macroconidia with micro-cycle conidiation pathway. Dactylellina cangshanensis is characterized by its fusiform, spindle-shaped, clavate or drop-shaped conidia with 2-4-septate. Phylogenetic analysis based on combined ITS, EF1-α and RPB2 sequence showed that these two species cluster together with D. ellipsospora with obvious genetic differentiation.

Aphid Host

Species from the genus Paralipsis are obligatory endoparasitoids of root aphids in the Palaearctic. It is known that these species are broadly distributed, parasitizing various aphid hosts and showing great biological and ecological diversity. On the other hand, this group of endoparasitoids is understudied and was thought to be represented by a single species in Europe, viz., Paralipsisenervis (Nees). However, recent description of two new species indicated the possibility of cryptic speciation and recognition of additional Paralipsis species in Europe. In this research, Paralipsis specimens collected during the last 60 years from eight European countries, as well as one sample from Morocco, were subjected to molecular and morphological characterization. Newly designed genus-specific degenerative primers successfully targeted short overlapping fragments of COI of the mitochondrial DNA. Molecular analyses showed clear separation of four independent lineages, two of which are the known species P.enervis and P.tibiator, while two new species are described here, viz., P.brachycaudi Tomanović & Starý, sp. n. and P.rugosa Tomanović & Starý, sp. n. No clear specialization of the taxa to a strict root aphid host has been determined. The recognized mitochondrial lineages were distinct one from another, but with a substantial within-lineage divergence rate, clearly indicating the complexity of this group of parasitoids, on which further research is required in order to clarify the factors triggering their genetic differentiation. We reviewed literature data and new records of Paralipsisenervis aphid host associations and distributions. A key for the identification of all known Paralipsis species is provided and illustrated.

Abstract. Mennerotodus Zhelezko, 1994, is an extinct lamniform shark known to occur in Paleogene strata of the Tethyan region of Asia and Europe. Although only a single species has been named, multiple subspecies have been erected and used as biostratigraphic tools in Asia. The genus has not been reported with confidence outside of the Tethyan region, but we have identified two new species of Mennerotodus from Paleogene deposits of the southeastern United States. Mennerotodus mackayi sp. nov. is described by teeth occurring in the lower Paleocene (Danian Stage) Pine Barren Member of the Clayton Formation of southern Alabama. A middle Eocene (Bartonian) species, Mennerotodus parmleyi sp. nov., is based on material occurring in the Clinchfield Formation in central Georgia. The early Paleocene record could indicate a North American origin for Mennerotodus relatively soon after the K–Pg event, with subsequent radiation to other parts of the world. The genus is likely more widely distributed than is currently known, but teeth can easily be overlooked due to their similarity to other taxa.
