A New Species

A new species of the genus Ocnogyna Graslin, [1837], O. mooseri sp. n. is described from north-eastern Libya. The female of the new species is fully winged but differs from all known species groups of Ocnogyna in a number of diagnostic features and is also externally reminiscent of Tajigyna gansoni Dubatolov, 1990 endemic to Tajikistan. The diagnostic comparison is made with the North African Ocnogyna advena (Fabricius, 1787) having externally similar males but brachypterous females and to the externally dissimilar Ocnogyna parasita (Hübner, 1790) species group having the most similar female genitalia structures.

A New Species

The monophyletic agelenid genus Barronopsis Chamberlin & Ivie is revised to include 6 species. The Cuban species B. campephila Alayón and B. cesari Alayón are synonomized under B. barrowsi (Gertsch) and B. jeffersi (Muma), respectively, and B. stephaniae new species is described. Natural history observations, distribution maps, diagnoses and descriptions, and a species identification key including B. texana (Gertsch), B. arturoi Alayón, and B. floridensis (Muma) are provided. Detailed descriptions of the male palpus and female genitalia, a review and evaluation of historical terminology used to describe agelenid palpal bulbs, and a discussion of the utility of certain male palpal characters in resolving phylogeny within Agelenidae are provided. Based on the morphology of the male and female genitalia and morphometric data, two species groups are recognized: a large-bodied B. texana species group (B. texana, floridensis, arturoi, jeffersi) and a small-bodied B. barrowsi species group (B. barrowsi, B. stephaniae). A cladistic analysis of Barronopsis, using Tortolena glaucopis (F. O. P.-Cambridge), Melpomene singula (Gertsch & Ivie), and species of Agelenopsis Giebel as outgroups identified three most parsimonious trees of 37 steps. The strict consensus tree yielded the following species relationships: (Agelenopsis (((B. texana, B. jeffersi), B. floridensis, B. arturoi), (B. barrowsi, B. stephaniae))))).Key words: Agelenopsis, revision, taxonomy, phylogenetic analysis

A New Species

A new species of the genus Cyana Walker, 1854, C. aurantifascia Volynkin, Černý & Dubatolov, sp. nov. is described from Vietnam. The Cyana dohertyi and Cyana phaedra species-groups are established. The new species belongs to the C. dohertyi species-group. Diagnostic comparisons are made with species of similar habitus belonging to the same and to other species-group. Adults, male and female genitalia of the new and related species are illustrated.

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.

The Barsine obsoleta species-group is reviewed. A new species, Barsine fossi Volynkin & Černý, sp. nov. is described from Vietnam. A new combination is established: Barsine obsoleta (Reich, 1937), comb. nov. The neotype is designated for Miltochrista gratiosa f. obsoleta Reich, 1937. Diagnoses for B. obsoleta and B. callorufa Wu et al., 2013 are given. Adults, male and female genitalia of the species reviewed and externally close species are illustrated.

The Neotropical Laccophilinae genus Laccodytes Régimbart, 1895 is redefined and revised. We recognize ten species, six of which are described as new. We define two species groups: the Laccodytes apalodes-group (L. apalodes Guignot, 1955, L. rondonia sp.n.), and the L. phalacroides-group (L. americanus Peschet, 1919, L. obscuratus sp.n., L. bassignanii sp.n., L. neblinae sp.n., L. olibroides Régimbart, 1895, L. phalacroides Régimbart, 1895, L. takutuanus sp.n., L. androginus sp.n.). Laccophilus pumilio LeConte, 1878, assigned to Laccodytes by Young (1954), belongs to an undescribed genus. Laccodytes species are lotic and most of them inhabit the north-eastern part of South America, apparently with Venezuela and Guyana as centre of diversity. Descriptions, illustrations and SEM photos of habitus, genitals and other diagnostic features are provided for each species, together with habitat notes, when known. We provide a key for species identification.

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.

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.
