New host and country records for European Tachinidae (Diptera)

The paper presents host records for 17 species of Tachinidae (of subfamilies Exoristinae and Tachininae) from the Czech Republic, Slovakia, Austria, Croatia, Macedonia, Italy, Spain, Portugal, and Bulgaria. New parasitoid-host couples are Exorista larvarum — Melanchra pisi; Exorista segregata — Catocala nymphaea; Sturmia bella — Hadena compta; Spallanzania multisetosa — Cycnia sordida (first host record); Tachina praeceps — Cucullia bubaceki; and Bithia modesta — Bembecia megillaeformis. New country records of tachinid species Rhacodinella apicata from the Czech Republic, Masicera pavoniae from Macedonia and Bithia demotica from Portugal are presented

Annotated host catalogue for the Tachinidae (Diptera) of the Czech Republic

An annotated host catalogue is given for the Tachinidae of the Czech Republic. It comprises 149 of 476 tachinid species which are currently known from this country (included the two new records cited below). 195 hosts are listed. The first host records of Tachinidae date back to the second half of the 19th century. The bibliography for the host records consists of 116 papers of 55 researchers. Several records of hitherto unpublished material are included. Phryxe setifacies and Anthomyiopsis plagioderae are first records for the Czech Republic

Type material examined. None. Type material should be probably housed in MFNB. Arrow (1910) mentioned that the type material of P. montana was stored in Nonfried’s collection. Later, Paulian (1960) wrote in his monograph to P. montana literally: “ Type: Himalaya, Zool. Mus. Humboldt Univ., Berlin ”. However, Mikšić (1987) and Alexis & Delpont (1998) both noted that type of P. montana cannot be found. Unfortunately, according to B. Jaeger (MFNB curator, personal communication, 2021) the database of Cetoniinae stored in MFNB did not list type or non-type material for Protaetia montana, although part of Nonfried’s collection (via Moser) is deposited in this museum. Hence, the type series is probably lost. Due to unavailable type material of P. montana, identification of bellow mentioned specimens is based on Alexis & Delpont (1998) and Jákl (2020).

Simi- anshan Nature Reserve, Dawopu, Jiangjin, Chongqing, alt. 1,060 m, Jing-Qiu CHENG et al. leg. Diagnosis. Elongate, with slender legs, color black (Figs.1–6). Antennae fulvous (with slightly darker scapus); antennal club longer in male. Pronotum suboctagonal, slightly wider at the middle of lateral margins, anterior angles slightly pointed; a narrow chalky band along margins; three chalky maculae on disc (“/ | \” shaped), sometimes partly (Fig. 22) or totally absent (Fig. 4) in female; dorsal surface with dense punctures (punctures larger in female). Elytra regularly covered with sparse yellowish setae (Fig 23); color of the inner area from humeral callus to apicosutural angle gradually from black to orange-brown. Yellowish chalky material on elytra: disc with two sinuate, transverse bands (usually, the anterior one divided into two parts, the posterior one divided into three parts); elytral juxtascutellar area with a narrow band along suture; elytral distal declivity with a crescent narrow transverse band. Pygidium strongly convex in male, while depressed medially in female; surface with concentric wrinkles, covered with pale yellowish chalky material at sides only (Figs. 14, 16). Sides of metasternum covered with chalky material. Abdominal sternite III to VI covered with chalky material (absent in median portion of III to V in female). Protibia bidentate (proximal tooth inconspicuous in male), without terminal spur in male. Parameres broad; apex rounded, slightly arcuate outwards; a short, auriform protuberance laterally protruding from basal part of paramere (Figs. 27–28). Measurements. Body length 14.2–15.1 mm, width 6.1–7.0 mm. Distribution. China: Chongqing (new record), Sichuan. Remarks. The figure numbers of the parameres of Paratrichius circularis and P. rufescens Ma, 1990 are reversed in the original description (Ma 1990), and this mistake was not corrected in Ma (1995). Ma (1990) claimed that P. circularis was closed to P. elegantulus (Moser, 1902) but differed in the body size, the color of elytra, and the shape of spots on elytra and pygidium. Actually, their coloration patterns are distinctly different: P. elegantulus resembles P. flavipes (Moser, 1901) which usually bears six maculae on elytron, while P. circularis has two chalky bands instead of maculae. The adults of P. circularis were observed visiting the flowers of Hydrangea sp. (Rosales: Saxifragaceae) in Mount Zhougongshan, Sichuan (Figs. 32–34) at a high elevation (about 1,600 m). While the label data of several specimens indicated that beetles were caught at an elevation around 1,000 m. These data suggested a broad altitude distribution range for this species.Published as part of Mückstein, Petr, Xu, Hao & Qiu, Jian-Yue, 2020, Description of a new species resembling Paratrichius circularis Ma, 1990 (Coleoptera: Scarabaeidae: Cetoniinae) from China, pp. 259-269 in Zootaxa 4763 (2) on pages 260-262, DOI: 10.11646/zootaxa.4763.2.8, http://zenodo.org/record/376267

Longer than wide, widest before the middle; each elytron with six striae dorsally and one on lateral declivity; each striae with a row of horseshoe-shaped punctures (few C-shaped), from second third more or less merged. Elytral suture black, uniformly narrow throughout its length. The whole area of elytra regularly covered with sparse yellowish setae (Fig. 29). Humeral umbone developed. Macropterous. Pygidium. Convex, wider than long, with apex rounded. Surface with concentric wrinkles, evenly and sparsely covered with slightly recumbent yellowish setae (Fig. 18). Ventral surface. Metasternal and abdominal ventrites covered with long yellow hairlike macrosetae, denser and longer medially than laterally. Anal sternites hollowed medially. Legs. Protibia bidentate, with proximal tooth inconspicuous, lacking terminal spur, inner margin of protibia with a row of yellowish setae. Mesotibia slightly curved, with inconspicuous oblique ridge at the apical third of outer margin and a pair of simply spurs apically; inner margin of mesotibia with a row of longer yellowish setae. Mesotarsi clad with minute yellowish setae, mesotarsomeres with some pale yellow brush-like bristles apically. Metatibia straight, with inconspicuous oblique ridge at the apical third of outer margin and a pair of simply spurs apically, the apical third of metatibia inner margin with a row of longer yellowish setae, outer margin with inconspicuous oblique ridge. Metatarsi extensively prolonged, 1.5 as long as mesotarsi; first metatarsomere as long as second; metatarsomeres clothes with minute yellowish setae and also with some pale yellow brush-like bristles apically.

Measurements. Body length 14.8–15.2 mm (male holotype 15.0 mm), width 6.2–7.0 mm (male holotype 6.8 mm). Variability. The chalky band along the margin of pronotum divided before scutellum in the male paratype (RMHK), and the anterior chalky band of elytra not divided into two parts in some individuals. Differential diagnosis. The new species is very similar to P. circularis, from which can be separated by following characters: anterior angles of pronotum slightly projected (distinctly projected in P. circularis); pronotal disc always without yellow chalky material; the posterior transverse sinuate band on elytra continuous (usually divided into three parts in P. circularis); lateral protuberances of parameres ensiform, distinctly long and slender (protuberance auriform in P. circularis). This new species also resembles Vietnamese species P. pejchai Mückstein, 2018 in appearance and parameres, but the anterior angles of pronotum is slightly projected (distinctly projected in P. pejchai), the color of elytra is darker, the scutellum and pronotal disc without chalky material, and the protuberances of parameres distinctly longer. Etymology. Named after Zdeněk Tesař (1907–1985), well-known Czech specialist on Scarabaeidae, in whose collection this newly described species was firstly found. Distribution. China: Guizhou. Remarks. According to the collecting data, the type specimens of Paratrichius tesari new species in Tesař’s collection were collected by missionary Pére Julien Cavalerie (1869–1927). Father Cavalerie worked at Guizhou province, China from 1894 to 1919, and collected a lot of plants and animals from the places he had worked (Wu & Tan 2003; Moussay & Appavou 2004). Pin-Fa (i.e. Pingfa), the exact locality given on his label of one paratype, is the type locality of many species (Léveillé 1906; Olivier 1909; Tsai & Rédei 2010). Pingfa (107°4′54.35″ E, 26°12′44.34″ N, alt. 1,000 m) is a small village in Yunwu township of Guiding County, located in the Yunnan–Gui- zhou Plateau with limestone mountainous environment. However, nowadays it is difficult to find a fit forest habitat for Paratrichius beetles around the village due to the environment changing. Subsequently, the authors (HX and JYQ) went to Maolan, a nearby nature reserve which is famous for its karst landscape at the edge of Yunnan–Guizhou Plateau. Finally, three males were captured on flowers of Viburnum sp. (Rubiales: Caprifoliaceae) during a one-week investigation (Figs. 35–36), but the amount of adults is distinctly less than other Paratrichius species, such as P. marmoreus (Moser, 1902) and P. tergorufus Ricchiardi, 2019. It is presumed that the peak of activity for adults of P. tesari new species should be slightly later than the collecting date, perhaps later June.Published as part of Mückstein, Petr, Xu, Hao & Qiu, Jian-Yue, 2020, Description of a new species resembling Paratrichius circularis Ma, 1990 (Coleoptera: Scarabaeidae: Cetoniinae) from China, pp. 259-269 in Zootaxa 4763 (2) on pages 262-268, DOI: 10.11646/zootaxa.4763.2.8, http://zenodo.org/record/376267
