A New Species

A new, extremely cryptic dendronotoid nudibranch from southern Spain is described. Lomanotus barlettai sp.nov. is intertidal and has been found under stones together with the thecate hydroids Kirchenpaueria pinnata and Ventromma halecioides. The body is elongate with a maximum of 36 cerata on each side. These are located on three pairs of notal ridges. Each ceras shows one or two characteristic constrictions. The veil bears two pointed processes on either side and there is a cephalic ridge. The body is brown with dense gold–brown pigmented superficial dots. The radular formula is 23 × 17.0.17 (7.5-mm specimen) and the innermost tooth of each half-row is denticulate. The other teeth exhibit more marked denticulation. Extensions of the digestive gland penetrate the cerata. The ampulla is surrounded by the hermaphroditic gland and there is only a curved seminal receptacle and a well-separated prostate. A comparison between L. barlettai and the other known species of the genus is presented. The validity of these species is discussed, together with the suggestion that five valid species can be distinguished: L. genei, L. marmoratus, L. vermiformis, L. phiops, and L. barlettai. The characteristics of these species are tabulated.

A New Species

Three new species of copepod crustaceans are described from material collected from anchialine and brackish habitats inand around the village of Walengkabola on the coast of Muna Island, to the southeast of Sulawesi. A new species of cy-clopoid, Paracyclopina sacklerae n. sp., was described from material collected from the tidal inflow entering into the bot-tom of sinkholes a few metres inland from the shoreline. Detailed comparisons are made with Paracyclopina orientalis(Lindberg, 1941), n. comb., a closely related congener here transferred from its original genus Cyclopetta Sars, 1913. Theassignment of Paracyclopina Smirnov, 1935 to the family Cyclopettidae is followed here despite uncertainty over the va-lidity of some of the families created by the break up of the former Cyclopinidae. Two new species of Boholina Fosshagen& Iliffe, 1989 are described, based on material from the same sinkholes and from caves located up to 700m inland fromthe coast and exhibiting further reduced salinity down to 1.8 ppt. One species, B. parapurgata n. sp., is very closely relatedto B. purgata Fosshagen & Iliffe, 1989 from Bohol island in the Philippines, the other B. munaensis n. sp., is very closelyrelated to B. crassicephala Fosshagen & Iliffe, 1989 also from Bohol island, but a number of fine scale differences in the leg 5 of both sexes are recognised in each case. Keys to valid species of both genera are provided.

A New Species

A new species of Tetragonopterus is described from the rio Jari, a tributary to the left margin of rio Amazonas, at the border between Amapá and Pará States, northern Brazil. It is morphologically diagnosed from the other species of the genus (T. argenteus, T. chalceus, and T. rarus new combination) by the lozenge-shaped spot on the caudal peduncle vs. rounded to square spot on the other species. Partial sequences of the mitochondrial gene Cytochrome Oxidase C subunit I, from representatives of all valid species of Tetragonopterus, including this new species, were analyzed. The obtained results revealed a significant genetic distance between the new species and its congeners. A discussion on the new combination, Tetragonopterus rarus, is also provided.

A New Species

The genus Homatula belongs to the order Cypriniformes and family Nemacheilidae. Nichols (1925) set up the genus as a subgenus of Barbatula by the type species of Nemacheilus potanini. Currently, it is recognised as a valid genus. Nineteen valid species have been already reported in the drainage of the Yellow, Yangtze, Pearl, Lancang, Red and Nujiang Rivers. H. variegata, H. longidorsalis, H. berezowskii and H. potanini are distributed in the Yangtze River drainage in China. H. laxiclathra is mainly distributed in the Weihe River, a tributary of the Yellow River. The remaining species are mainly distributed in the rivers of Yunnan Province. Homatula guanheensis sp. nov., a new species, is described from the Guanhe River of the HanJiang River drainage (a tributary of the Yangtze River), Xixia County, Henan Province, China. It can be distinguished from its congeners by a combination of the following characters: the vertical brown bars on the body are wider than their interspaces, numbering 19–22; predorsal body partially scaled; the lateral line complete; adipose crest on caudal peduncle not reaching forward; the position of the anal-fin origin and the intestinal form. The new species displays distinct molecular divergence in the Cytochrome oxidase I (COI) and Cytochrome b (Cyt b) genes.

The first finding of the genus Greeffiella Cobb 1922 (Greeffiellinae, Desmoscolecidae) in the Black Sea is presented. Two mature females were collected in Northwestern Shelf of Crimea in strongly silted fine sand with detritus at a water depth of 56 m. Greeffiella sp. is described and illustrated. The absence of males in the collections does not allow the authors to present it as a new species for science or to identify it as one of the known species of the genus Greeffiella. Black sea specimen is distinguished from the other known species of the genus Greeffiella with the presence of 8 pairs of thicker specific setae along the body, the basis of which looks like a small lamina, but without hairs, which was previously described for G. pierri Schrage & Gerlach, 1975 and G. australis Schrage & Gerlach, 1975. The short esophagus at the base has two salivary glands and a cardia. Cardia has not been mentioned before for the known species of the genus Greeffiella.

In this paper we describe a new genus and a new species of Chiridotidae based on specimens collected in shallow water off the South-eastern Brazilian coast. Gymnopipina ikamiaba gen. nov. et sp. nov. is characterized by the complete absence of dermal ossicles in the body, and it differs from the other ossicleless apodids in the number of tentacles and of Polian vesicles, and in the morphology of the calcareous ring. Although not formally tested with a phylogenetic framework, apodids have apparently lost their dermal ossicles multiple times. If these reversions hold true, Gymnopipina gen. nov. represents the fourth independent loss of dermal ossicles in the class Holothuroidea. An identification key to the Brazilian apodid species is also provided.

Plesiomorphic State

The number of antennal segments in adults of the different families and genera in the insect order Thysanoptera varies between five and nine. The plesiotypic number is considered to be nine (Zhang et al. 2019), and fossil thrips reported to have 10 to 15 segments (Tong et al. 2019) are generally considered to be aberrations in which the terminal segment bears transverse striae. The 9-segmented condition occurs particularly amongst species that exhibit several other characters in a plesiomorphic state, including all Melanthripidae, two genera of Merothripidae, also most species of Fauriellidae, Stenurothripidae, Heterothripidae, and Aeolothripidae (Mound et al. 1980). Curiously, members of a few genera of Thripidae (Palmer & Mound 1985; Minaei 2012) also have nine antennal segments, but this is considered a reversion from the 8-segmented condition that is assumed to be plesiomorphic for that family (Zhang et al. 2019). Variation between eight and nine segments occurs in the genus Anaphothrips, and within that genus a few species exhibit intraspecific variation in antennal segmentation (Mound & Masumoto 2009). Intraspecific variation in various characters, including body size, color and wing length, is well documented for the order Thysanoptera (Mound 2005 a, b). However, amongst the 207 listed species of Aeolothripidae there has never been any report of a species bearing antennae with other than nine segments, although these vary in length and shape amongst the different genera. We here describe from Iran a curious species of the genus Aeolothrips that is unusual in having only seven antennal segments, with the number reduced to six or even five in a few individuals in which the terminal segments are fused. These females with 7-segmented antennae were initially considered to be aberrant individuals of some other species. However, 25 females with such antennae have been collected over two years, all from a group of Tamarix trees. Despite extensive studies on the genus Aeolothrips in Iran (Alavi & Minaei 2018, 2019), with 30 species now being recorded from this country, no other species has been found with the same colour pattern of the body and fore wings. We therefore conclude that the available specimens represent a valid species in which the antennal segmentation is reduced, and with the terminal segments unstable.
