A new species of Caenis Stephens, 1835 (Ephemeroptera: Caenidae) from Tamil Nadu, Southern India

A new mayfly species Caenis maduraiensis sp. nov. is described and illustrated from nymph and adults collected from lentic habitat around Madurai. The nymph can be distinguished by the following characters: anterior margin of labrum with row of bipectinate setae longer laterally and a group of highly fringed setae behind emargination; and hind claw long, slender and hooked with row of denticles. Adults are characterized by prosternal triangle with slightly concave sides, tip acutely pointed; apical part of forceps abruptly narrowed to the tip, with a long apical spine, and few trichomes on surface.

Revision of the Theopea genus group (Coleoptera, Chrysomelidae, Galerucinae), part III: Descriptions of two new genera and nine new species

This publication treats species within Theopea and closely allied genera that were not covered in the previous two revisions. Three species of Theopea Baly, 1864 are treated herein, with T. bicolor Kimoto, 1989 and T. mouhoti Baly, 1864 redescribed, and T. bicoloroidessp. nov. described. A new genus that we consider closely related to Theopea, Pseudotheopeagen. nov., is described. This new genus can be recognized with the presence of reticulate microsculpture on the vertex of the head and pronotum and presence of an apical spine on each metatibia. The following species are transferred to Pseudotheopea as new combinations: Theopea aeneipennis Gressitt & Kimoto, 1963, T. azurea Gressitt & Kimoto, 1963, T. clypealis Medvedev, 2015, T. nigrita Medvedev, 2007, T. smaragdina Gressitt & Kimoto, 1963, T. similis Kimoto, 1989, and T. subviridis Medvedev, 2012. Theopea subviridis Medvedev, 2012 is regarded as new synonym of Pseudotheopea similis (Kimoto, 1989). In addition, six new species of Pseudotheopea are described: P. borerisp. nov. from India, P. gressittisp. nov. from Philippines, P. hsingtzungisp. nov. from Laos, P. kimotoisp. nov. from Laos, Thailand, and Vietnam, P. leehsuehaesp. nov. from Laos, and P. sufangaesp. nov. from Taiwan. A second new genus regarded as closely related to Pseudotheopea, Borneotheopeagen. nov., can be recognized by possessing uniform antennae in both sexes and lacking an apical spine on each metatibia. Two new species of Borneotheopea are described from Borneo: B. jaklisp. nov. and B. kalimantanensissp. nov.

Gynacantha dryadula sp. nov. from the Guiana Shield (Odonata, Anisoptera: Aeshnidae)

The new species is described and illustrated on the basis of two reared, subteneral males from Brazil, their larval exuviae, a mature male from French Guiana, a mature female from Venezuela, and a mature female from Surinam. One of the Brazilian males is the holotype (BRAZIL, Amazonas State, Manaus, Reserva Florestal Ducke, BR 174-km 26, trail to Acará creek, 02º55’47”S, 59º58’22”W, 0.7 m elevation, deposited in INPA). The new species (total length 50–54 mm) differs from other small species of same genus by color pattern of thorax, middle and hind tibiae dark with external (dorsal) yellow streak, male cercus with truncated tip lacking apical spine, and male epiproct reaching or slightly surpassing midlength of cercus. The larva, besides of its small size (28–31 mm), has an epiproct with well-developed and slightly diverging apical spines and an unusually long paraproct.

Supplementary description of Cycas hongheensis (Cycadaceae) from Yunnan, China and its phylogenetic position

Cycas hongheensis was firstly proposed as a distinct taxon in 1994 and formally described two years later based on vegetative materials only. Here, the reproductive organs of this species, namely, the female cone, male cone and seeds are supplemented for description as these fertile materials were found for the first time at the type locality. Furthermore, the phylogenetic position of this species as being the only endemic member of Cycas sect. Indosinenses in China was investigated. The conflicting phylogenic results between chloroplastic (cpDNA) and nuclear DNA (nDNA) are corresponded with the inconformity characters of morphology of this species. The characters of lacking indumentum on ovules and the distinct apical spine of megasporophyll are corresponding to nDNA result while the characters such as the soft and rudimentary apical spine of the microsporophyll and the absence of fibrous layer inside the sarcotesta comform to cpDNA result. For the taxonomy, we agree this species to be classified into Cycas sect. Indosinenses for the obvious morphological characters of megasporophyll and ovule as well as deeper evidence from phylogeny based on nuclear data, as biparental inherited nuclear genes could offer more comprehensive genetic information than maternal inherited cpDNA.

Chrysoteuchia ningensis sp. n., a new pyralid moth (Lepidoptera: Crambidae) from China

A new species Chrysoteuchia ningensis Li, sp. n. is described from China. The new species is similar to C. pyraustoides and C. shafferi by the phallus produced to a long and thin apical spine in the male genitalia. Images of both adult and genitalia of the new species are provided, along with two topographic maps of China showing the localities where Chrysoteuchia are recorded. Type specimens are deposited in the Insect Museum, Jiangxi Agricultural University, Nanchang, China.

Two new species of Halicyclops (Copepoda, Cyclopoida) from the estuarine interstitial waters in South Korea

Two new cyclopoid species belonging to the genus Halicyclops Norman, 1903 are described from brackish waters in South Korea: H. lanceolatus sp. nov. and H. pumilus sp. nov. Halicyclops lanceolatus was collected from two river mouths, both connected to caves. It belongs to the thermophilus group in showing 3,4,4,3 spine formula on legs 1-4 and lateral process on the genital double-somite. Among the members of the species group, it is closely allied with H. thermophilus Kiefer, 1929 and H. uncus Ueda and Nagai, 2009. However, it differs from them by a stout, lanceolate inner apical spine on leg 5 exopod, very short lateral process of the genital double-somite, short caudal rami, and shorter inner apical spine on the third endopodal segment of leg 4. Halicyclops pumilus was collected from interstitial waters of estuarine sandy beaches, and it is characteristic in having a single inner seta on the second endopodal segments of legs 2-3, and quadrate shape of leg 5 exopod with stumpy spines.

On a second species of Envia Ott & Höfer, 2003 (Araneae, Microstigmatidae), with notes on the sympatric type species

A second species of the microstigmatid spider genus Envia Ott & Höfer, 2003 is described from Manaus, Amazonas, Brazil. A new diagnosis, new records and notes on intra-specific variation in the tibial apophysis of the first leg of the male Envia garciai Ott & Höfer, 2003 are also provided. Males of Envia moleque n. sp. are readily recognizable by the copulatory bulb with a strong apical spine on weakly differentiated paraembolic apophysis and by tibia I lacking an apophysis, which is instead represented by a modified retroventral apical spine in the type species. Females can be recognized by the spermathecae with globose distal receptaculum. Both known species in the genus are sympatric at least at the UFAM Experimental Farm, Manaus, Amazonas, Brazil, the type locality of the new species.

A new species of copepod (Siphonostomatoida: Caligidae) parasitic on the striped trumpeter, Latris lineata (Forster), from Tasmania

A new species of caligid copepod (Siphonostomatoida), Caligus nuenonnae n. sp., is described based on material collected from the body surface of striped trumpeter [Latris lineata (Forster)] reared at the Tasmanian Aquaculture and Fisheries Institute, Marine Research Laboratories, Australia. Caligus nuenonnae n. sp. is characterised by the following combination of features: 1) female genital complex with a mid-lateral indentation and highly concave posterior margin; 2) 1-segmented abdomen in the female that is about one-third the length of the genital complex; 3) distinctly broader first abdominal somite relative to the second abdominal somite in the male; 4) antenna with a spatulate process on the proximal segment; 5) recurved postantennal process without a basal accessory process; 6) female maxilliped with a proximal ridged protrusion on the corpus; 7) sternal furca with widely separated, apically truncate tines; 8) distal exopodal segment of leg 1 with a lateral flange on each apical spine and an accessory process on apical spines two and three; 9) leg 3 protopod with two adhesion pads on the dorsolateral surface; 10) leg 4 exopod 2-segmented, with I-0; I, III armature; 11) terminal exopodal segment of leg 4 with the outer apical spine being slightly shorter than the middle apical spine; 12) male maxillulary dentiform process with numerous small points embossed on the surface; and 13) male legs 5 and 6 represented by distinct lobate projections.

Metahadzia Uncispina, A New Amphipod from Phreatic Ground-Waters of the Guadalquivir River basin of Southern Spain

Metahadzia uncispina n. sp. is described, being the second species of the genus on the Iberian Peninsula. The new species, well characterized by the transformation of the apical spine on the endopodite of the male uropod 2, is undoubtedly closely related with M. tavaresi (Mateus & Mateus, 1972) from the south of Portugal. Comments are made about recent emendations of the original concept of the genus Metahadzia Stock, 1977.

KEY TO ADULT MALES OF CONIFER-FEEDING SPECIES OF CHORISTONEURA LEDERER (LEPIDOPTERA: TORTRICIDAE) IN CANADA AND ALASKA

A key, based on morphological characters of adult males, separating six traditionally recognized conifer-feeding Choristoneura species, C. pinus Freeman, C. lambertiana (Busck), C. fumiferana (Clemens), C. occidentalis Freeman, C. biennis Freeman, and C. orae Freeman occurring in Canada and Alaska is provided and illustrated. The newly discovered morphological features, the aedeagus of C. fumiferana and C. pinus with a short apical spine and with many microscopic spicules on the distal half, are used to separate these two species from their western allies C. occidentalis, C. biennis and.C. orae.
