A New Species

A new species group, the brevis-group, is established for two new species of the fig wasp genus Sycophaga Westwood (Hymenoptera: Agaonidae) reared from the monoecious fig tree Ficus orthoneura (Moraceae, Ficus, subgenus Urostigma) in China. The two new species, S. brevis n. sp. and S. diutius n. sp. are described and illustrated, supplemented by COI sequence data. In contrast with two other species groups newly recognized in Sycophaga, the explorator-group for species previously classified in Apocryptophagus Ashmead and the sycomori-group for other species previously classified in Sycophaga, the brevis-group is uniquely defined by the long pronotum of females and a Ficus host within the subgenus Urostigma.

A New Species

A new species, Baetis pentaphyllus sp. nov., is described on the basis of larvae from the Far East of Russia (type locality Bolshoi Garmakan River). Larvae of Baetis pentaphyllus sp. nov. may be distinguished from other Baetis species by the presence of only five pairs of tergalii on segments III–VII. The mitochondrial COI sequence obtained from the described species was compared with the data present in GeneBank and BOLD. The DNA barcodes allowed discrimination of B. pentaphyllus sp. nov. from other species of Baetis with available sequence data. The average interspecific K2P distances were 10–15%, which are values well above those associated with intraspecific variation. COI sequences as well as 36 morphological larval characters were analysed using Bayesian inference to relate the described species to the recognized species-groups of the Baetis genus. B. pentaphyllus sp. nov formed a sister clade to B. vardarensis + B. lutheri which belong to the Baetis lutheri species-group.

Subjective Synonym

The genus Thysanoptyx Hampson, 1894 is a member of the subtribe Lithosiina, tribe Lithosiini (Arctiinae). It was described as a monotypic genus for Lithosia tetragona Walker, 1854 from Silhet [Sylhet], [Bangladesh].Hampson (1900) treated Thysanoptyx as a synonym of Eilema Hübner. Daniel (1954) placed it under Lithosia Fabricius, whereas Birket-Smith (1965) treated it as a junior subjective synonym of Teulisna Walker. Later, Kishida (1993) considered Thysanoptyx Hampson as a valid genus. Fang (2000) reported four species from China: Thysanoptyx tetragona (Walker, 1854), T. fimbriata (Leech, 1890), T. signata (Walker, 1854), and T. brevimacula (Alphéraky, 1897). However, the male genitalia of T. tetragona figured by Fang (2000) belong to a probably new species (Singh, pers. obs.). Holloway (2001) considered four species, Thysanoptyx tetragona, T. oblonga (Butler, 1877), T. sordida (Butler, 1881), and T. incurvata Wileman & West, 1928 from Oriental region. Kirti & Singh (2015) described a new species, T. pseudotetragona Joshi, Singh & Kirti from South India (Kerala) and reported T. incurvata for the first time from India. However, the new reporting of T. incurvata seems to be incorrect (see the remark below). Recently, Volynkin & Dubatolov (2017) subdivided Thysanoptyx into five species groups: tetragona species group, oblonga species group, sordida species group, signata species group, and fimbriata species group, with the description of two new species: T. indosinica Volynkin & Dubatolov, 2017 from Thailand, Cambodia and Vietnam and T. mirifica Volynkin & Dubatolov, 2017 from Vietnam. At present the genus comprises 10 valid species distributed from China, Taiwan to India and South East Asia.

The genus Carlogonus Demange, 1961, is diagnosed, and its relationship with other members of the Harpurostreptini Hoffman, 1980 is discussed. A new species, Carlogonus gayathri sp. nov. is described and illustrated from the southern Indian State of Kerala, and its DNA barcoding data is presented. Phylogenetic analysis based on mtDNA sequence data revealed that Carlogonus is sister-taxon to Thyropygus Pocock, 1894. Two species-groups are recognised in Carlogonus: the exaratus-group is characterised by a single tibial spine on the gonopod, while the acifer-group has paired tibial spines. A dichotomous key is presented for the known Carlogonus spp., and the current distribution of the genus is mapped.

A New Species

Two new species-groups of the cantharid genus Stenothmeus Bourgeois are defined, S. laterophysus species-group and S. notaticollis species-group. The S. laterophysus species-group is composed of two species, including S. laterophysus Švihla, 2004 and a new species, S. nigritibius Y. Yang et H. Liu, sp. nov., and characterized by the pitch black elytra and bicolored legs, the subrounded pronotum with widely rounded anterior angles and projecting posterior angles, male genitalia with slender ventral processes of parameres which are slightly bent inwards at apical parts, laterophyses tilting ventrally at an angle of more than 45° with dorsal plates, compressed at apical parts, as well as the slender spermathecal duct, extremely long spermatheca and diverticulum. The S. notaticollis species-group consists of five species, including S. notaticollis (Gorham, 1895), S. bourgeoisi Wittmer, 1974, S. tamil Švihla, 2011 and two new species, S. parameratus Y. Yang et S. Ge, sp. nov. and S. acutiapicis Y. Yang et X. Yang, sp. nov., which is differentiated from the S. laterophysus species-group by the more variable body coloration, elytra pitch black or black brown or pale-yellow, male genitalia with thick or flattened ventral processes of parameres which are diverging apically, laterophyses parallel to dorsal plates, expanded at apices, as well as the stout spermathecal duct, moderately long spermatheca and diverticulum. The above species are illustrated with photographs of habitus, male genitalia, abdominal sternites and internal genitalia of female. A key for the identification of these species is provided and a distribution map is presented.

Tropical South America

The giant water bug fauna from tropical South America remains poorly known. Three species of Belostoma Latreille (Belostoma fittkaui De Carlo, B. sayagoi De Carlo and B. hirsutum Roback & Nieser) have been cited only a few times in the literature. These three species are remarkable since they represent an extreme variation for the genus, with article II of the labium distinctly shorter than article III. Here, the synonymy of B. hirsutum with B. sayagoi is proposed based on examination of type material and additional specimens. Further, B. fittkaui and B. sayagoi are redescribed, including discussion about comparative morphology with congeners. A new species group is proposed for these species and a key to the Belostoma species groups is provided. Distribution records are also updated.

Eutarsopolipus burwelli sp. nov. and E. echinatus sp. nov. (Acari: Podapolipidae) are described from Nurus medius Darlington, 1961 (Coleoptera: Carabidae), a large burrowing carabid beetle found in the rainforests of coastal central Queensland, Australia. Eutarsopolipus burwelli belongs to the ochoai species group, which is herein refined, and E. echinatus is placed tentatively in the pterostichi species group. A revised key to the species groups of Eutarsopolipus is provided. The synhospitalic species of Eutarsopolipus are reviewed and synhospitality within the genus is discussed.

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.

Two new species groups are established for East Palaearctic species of the genus Anthobium Leach, 1819: the atrocephalum group containing the widespread Palaearctic A. atrocephalum (Gyllenhal, 1827), A. formosanum Shavrin, sp. n. (Taiwan), A. hammondi Watanabe, 1990 (Japan), A. lackneri Shavrin, sp. n. (Japan: Hokkaido), and two Chinese species, A. kabateki Shavrin, sp. n. (Yunnan, Gansu) and A. marci Shavrin, sp. n. (Sichuan); the convexior group containing four new species from China: A. convexior Shavrin, sp. n. (Shaanxi, Sichuan), A. auritum Shavrin, sp. n. (Yunnan), A. kabaki Shavrin, sp. n. (Sichuan), and A. semenovi Shavrin, sp. n. (Sichuan). New species are described and illustrated. The species groups are defined, briefly discussed and a key to the species of each group is given. Additionally, a new species of the morchella group, A. inopinatum Shavrin, sp. n. (China: Yunnan) and the nigrum group, A. bengalicum Shavrin, sp. n. (India: West Bengal), are described and illustrated. New faunistic records of A. reflexum (Reitter, 1891) from Kazakhstan, Kyrgyzstan, and Tajikistan are provided.
