The adult stage of a new flower fly species, Copestylum enriquei sp. nov. (Diptera: Syrphidae) is described based on a single male collected in pristine rainforest in the Amazonian region of Colombia (type-locality: Florencia, Caquetá) and two females from a conserved forest in Suriname (Para and Brokopondo). Copestylum enriquei sp. nov. belongs to the C. vagum species group and is similar in appearance to Copestylum vagum (Wiedemann), C. musicanum (Curran), C. tenorium Ricarte & Rotheray, and C. chapadensis (Curran) from which it differs by the gena and face separated by a very broad brown vitta; scutum orange except for the wide medial vitta, which is dark and metallic, ending before the prescutellar region, with the apical margin M-shaped; tibiae dark-brown, except yellow on basal 1/4. The male genitalia of C. enriquei sp. nov. are unique and striking among the C. vagum species group, characterized by the epandrium and cercus black, contrasting with the colour of hypandrium and surstylus, which are orange; epandrium with a dorsal extension, a novel character among this species group, in addition to the L-shaped surstylus, with two pairs of rounded ridges in the dorsal edge, similar to a small deer antler in velvet. Images of type material, including photographs of male genitalia are provided. A comparison of the diagnostic characters is provided as well as modifications to the previous keys to distinguish C. enriquei sp. nov. from the other species of the C. vagum group. The species Copestylum araceorum Ricarte & Rotheray and C. tenorium Ricarte & Rotheray are recorded for the first time in the Amazonian rainforest in Colombia.

A New Species

Dichagyris is a diverse genus with a Holarctic distribution. Only a few taxa of the subgenus Albocosta Fibiger & Lafontaine, 1997 occur in the northwesternmost part of the Oriental region. The genus is most diverse in Turkey, Iran and the Central Asiatic high mountains. However, there is a distinct Sino-Tibetan group of species, possibly representing an undescribed subgenus. However, this idea is provisional and awaits revision of the genus. For present purposes, we assign these species to the subgenus Dichagyris. They share the following putative synapomorphies: black, dark brown or dark greyish forewing ground colour (with one exception), with obscure, reduced wing pattern and a broad-based, short, conical harpe in the male genitalia. Species of this group can be subdivided to two species-groups. In the astigmata-group which was mentioned for the first time by Hreblay et al. (1998) but without description or diagnosis from the minuta-group, the vesica is elongate and tubular (males), the appendix bursae and corpus bursae are long, sack–like, almost equal in size (females). In the minuta-group, the vesica is more ample than in the astigmata-group, and coiled, and the appendix bursae is globular and much shorter than the corpus bursae. The astigmata-group includes Dichagyris astigmata (Hampson, 1906), D. gansuensis Hreblay & Ronkay, 1998, D. geochroides (Boursin, 1948) and D. vargazoli (Gyulai & Ronkay, 2001). The minuta-group comprises D. minuta Hreblay & Plante, 1998 and D. kormos Gyulai & Ronkay, 2001. During a research expedition in Sichuan in 2019, the existence of a third species in the minuta-group was recognized, which is described here. In addition, the female and its genitalia of D. gansuensis, which was described by Hreblay & Ronkay (1998) based on a single male, are illustrated here for the first time.

Two new species of the genus Agrisius Walker, 1855, A. orhanti Volynkin, Dubatolov & Kishida, sp. n. and A. leloii Volynkin, Dubatolov & Kishida, sp. n. are described from South Laos and Vietnam respectively. A. orhanti sp. n. belongs to the A. japonicus Leech, 1889 species-group. Whereas, the male genitalia structure of A. leloii sp. n. is intermediate between those of the A. japonicus and the A. guttivitta Walker, 1855 species-groups, therefore, it is assigned to a separated species-group (the A. leloii species-group). Agrisius dubatolovi Orhant, 2012 is downgraded as a subspecies of A. japonicus: Agrisius japonicus dubatolovi Orhant, 2012, stat. nov. Female genitalia of species of the A. japonicus and most of the A. guttivitta species-groups are illustrated for the first time.

Since its original description from the Amazonian region, the tick species Amblyomma goeldii Neumann, 1899 has been misidentified with Amblyomma rotundatum Koch, 1844 in different countries of the Neotropical region. Because of this, some authors have considered that the only confirmed records of A. goeldii were from French Guyana. Herein, we reviewed all specimens of A. goeldii that have been deposited at two tick collections in Brazil. In addition, we describe the nymphal stage of A. goeldii for the first time. A total of 10 unpublished records of the adult stage of A. goeldii are recorded from the Amazonian region of Brazil, confirming the occurrence of A. goeldii in this country. Except for one record on the snake Boa constrictor Linnaeus, all records of A. goeldii reported in the present study were from anteaters (Pilosa: Myrmecophagidae). Our results, in conjunction with previous literature records, indicate that anteaters and large snakes are important hosts for the adult stage of A. goeldii. The nymph of A. goeldii is morphologically similar to the nymphs of Amblyomma romitii Tonelli-Rondelli, 1939, Amblyomma dissimile Koch, 1844, and A. rotundatum. We present a modification of a previously published taxonomic key of Amblyomma nymphs from Brazil, in order to perform taxonomic identification of the nymph of A. goeldii based on external morphology. The geographical distribution of A. goeldii appears to be restricted to the Amazonian region. There were no previous host records for the immature stages of A. goeldii, thus it is expected that the present nymphal description will facilitate further works on the ecology of this poorly studied tick species.

Chrysoclista karsholti Šumpich, sp. n., is described from a single male collected in Turkey. This species most resembles C. germanica Šumpich & Huemer, 2016, but differs in the colouration of the dorsum of the forewing and in the shape of the valva in the male genitalia. Differences in the DNA barcode region between these two species are rather low compared to differences between other species of the genus. Chrysoclista germanica, previously known only from the holotype, is recorded from the Czech Republic for the first time. An updated checklist of western Palaearctic Chrysoclista Stainton, 1854 is provided.

A New Species

The spider genus Austrochilus comprises only six species known from Chile and Argentina. Here, we describe a new species, Austrochilus parwis sp. n., based on a single male and several females. The new species was found in Chile (Region IX) and, based on characters in the male and female genitalia, seems to be closely related to A. forsteri Grismado, Lopardo & Platnick, 2003. The female genitalia were investigated using X-ray microscopy, revealing for the first time the internal organization of austrochiline female genitalia. Furthermore, we provide a comparative documentation of the male genitalia of austrochilines based mainly on type material, and comment on the recently proposed nomenclatorial changes to the family name Austrochilidae.

The holotype of Cyana bianca (Walker, 1856) is examined. As a result, the species previously considered as C. bianca is described as new: C. abrupta Volynkin & Černý, sp. nov. (NE India, Nepal and Bangladesh). Cyana bianca is assigned with Cyana insularis (Draudt, 1914) species-group. Another taxon of this group, C. malacca Lourens, 2017 is synonymized with C. carmina (Černý, 1993) and downgraded to the subspecies level: Cyana carmina malacca Lourens, 2017, syn. & stat. nov. The male genitalia of the recently described C. juliettae Lourens, 2017 are illustrated for the first time.

Sabethes (Sabethoides) glaucodaemon was described for the first time by Dyar & Shannon (1925) based on the adult female. Later, descriptions of the male genitalia and parts of the fourth-instar larva and pupa were published by other authors. No one has described the female genitalia or made a complete description of the larva and pupa. The aim of this study was to redescribe Sa. glaucodaemon in the adult stage, including the male and female genitalia, and the pupa and fourth-instar larva. All stages are illustrated. Distinctions from Sa. (Sbo.) tridentatus are discussed.

Here we present a synthesis on the current knowledge of sphodrine carabids of the southern Levant (Israel, areas under Palestinian control, Lebanon, Jordan, Egypt east of Suez Channel: Sinai). A key for the identification of genera, subgenera and species is provided. Two new species are described: <em>Taphoxenus</em> (<em>Lychnifugus</em>) <em>ziegleri</em> sp. n. is described from Jordan (Type locality: Madaba), close to <em>T</em>. (<em>L</em>.) <em>meridionalis</em> Casale, 1988 (valid species), but markedly distinct for several characters both in external features and male genitalia. <em>Laemostenus</em> (<em>Laemostenus</em>) <em>sinaiticus</em> sp. n. is described from southern Sinai (Type locality: St. Catharina Monastery). This species belongs to the <em>L. quadricollis</em> species group (in the sense of Casale, 1988), and is close to <em>L. aegyptiacus</em> Schatzmayr, 1936. An updated key for the identification of the species of this group known so far in that area, which includes both epigean and subterranean species, is provided. The diagnostic features of all species newly described are illustrated, and their possible relationships are discussed. Furthermore, the features of male genitalia of <em>Laemostenus</em> (<em>Laemostenus</em>) <em>aegyptiacus</em> Schatzmayr, 1936 and <em>Laemostenus</em> (<em>Laemostenus</em>) <em>libanensis</em> (Piochard de la Brûlerie, 1876) are illustrated for the first time. The latter, known so far from the remains of the holotype specimen, is redescribed from material recently sampled in Lebanon.
