Morphometry and chaetotaxy of the nymphs of Ectemnostega (Ectemnostegella) quechua (Bachmann 1961) (Insecta: Hemiptera: Heteroptera: Corixidae)

The egg and the five nymphal instars of Ectemnostega quechua are described and illustrated for the first time. The eggs of Ectemnostega have a short stalk, and the shape, size and chorionic structure differ among groups of species. The nymphal characters most useful in identifying instars I–V of Ectemnostega are: body length; number of rostrum sulcations; number of setae on inner surface of protibiotarsus; spines and setae, and spines on posteroventral surface of mesofemur and mesotibia, respectively; setae on posterodorsal surface of mesotibia and mesotarsus; spines and setae on anteroventral surface and setae on posterior surface of metatibia; swimming hairs on anteroventral and posterodorsal surfaces of metatarsus; and the grade of development of wing pads. The nymphs of E. quechua can be easily distinguished from other species of Ectemnostega by the number of spines and setae on the posteroventral surface of mesofemur.

Description of the immature stages of Sigara (Tropocorixa) santiagiensis (Hungerford, 1928) (Insecta: Heteroptera: Corixidae)

The immature stages of Sigara santiagiensis are described and illustrated for the first time. The eggs of Sigara can be distinguished by the chorionic surface. The main characters separating the five nymphal instars of S. santiagiensis are: body and head lengths; body, head and eye widths; ocular index; numbers of transverse sulcations of the rostrum, setae on the inner surface of protibiotarsus, campaniform sensilla on posterior surface of protrochanter, spines on posteroventral surface of mesotibia and on tibial comb of metaleg, long, slender setae on posterodorsal surface of mesotarsus, spines and swimming hairs on anteroventral and posterodorsal surfaces of metatarsus; and grade of development of the wing pads. The body length, the chaetotaxy of the mesonotum, profemora and metafemora, protibiotarsus, metatibia, metatarsus and urosternites distinguish species or group of species of instars I and V of some of the species of the genus Sigara described up to now.

Taxonomic revision of the genus Littorophiloscia Hatch, 1947 (Crustacea,Isopoda, Oniscidea) with description of six new species

In the present revision 15 species of Littorophiloscia are recognized. Six species, namely L. tropicalis, L. koreana, L. amphindica, L. pallida, L. bifasciata and L. hawaiiensis are described as new. Littorophiloscia isabellae (Vandel, 1973) is considered to be a junior synonym of L. albicincta (Vandel, 1973), and Philoscia dartevellei Brian, 1953 and Vandeloscia orientalis Roman, 1977 are considered to be junior synonyms of L. culebrae (Moore, 1901). Alloniscus compar sens. Vandel, 1952 nec Budde-Lund, 1893 is considered to be distinct from L. riedli (Strouhal, 1966) and it has been renamed L. tropicalis sp. nov. The genera Bilawrencia Vandel, 1973, Helenoscia Vandel, 1977, Vandeloscia roman, 1977 and Sayoscia Schultz, 1983 are considered to be synonymous with Littorophiloscia. Diagnostic characters of all the species are illustrated. A map and comments on the distribution of the 15 species are included.

Synopsis of the genus Pseudoperma Dillon and Dillon, 1946 (Coleoptera: Cerambycidae), with description of a new species

A synopsis of Pseudoperma is provided. This genus mainly differs from Onocephala and Stethoperma by the antennal tubercles well separated; antennae relatively short, in the female subequal to the body length; and scape and third antennomere subequal in length. Pseudoperma includes two species, P. chalcogramma (Bates, 1887) and P. patruelis (Breuning, 1940), both from Brazil; herein we describe one new species, Pseudoperma lingafelteri sp. nov. from Brazil (Rio de Janeiro). This species differs from its congeners mainly in having the frons and occiput covered with greyish pubescence, and the sides of the elytra with several interrupted or coalescent vittae. We provide new distribution data for Pseudoperma patruelis (Breuning, 1940) from Brazil, Minas Gerais, São Paulo and Santa Catarina, as well as illustrations and a key to the species of Pseudoperma.

Notes on the Amazonian genus Hyogonia China (Hemiptera: Cicadellidae: Proconiini) with a description of a new species

Oncometopia batesi Distant, described from northern Brazil (State unknown), is transferred to the genus Hyogonia China. Hyogonia brasiliana sp. nov. is described from Northern Brazil, Pará State, the easternmost record of the genus. The new species is easily distinguished from all other Hyogonia species by the following combination of characters: (1) pronotum without distinct transverse contrasting band; (2) pygofer with short processes that do not attain its apex; (3) both pairs of aedeagal atrial processes divergent and short, never longer than aedeagal shaft; and (4) aedeagal caudal pair of atrial processes with bases close to each other, appearing as a single bifurcated robust process. Hyogonia batesi and H. brasiliana, together with an unidentified female from Acre State, represent the first authentic records of the genus Hyogonia from Brazil. Previous records of H. reticulata (Melichar) and H. youngi Emmrich and Lauterer from Brazil are erroneous as their recorded locality ‘Cumbase’ is most probably located in Peru (San Martín Department). Other new records from countries and major federal divisions are noted as follows: the genus Hyogonia (unidentified species) from Barinas State (Venezuela); H. batesi from Ecuador (Orellana Province); H. reticulata from Amazonas and Junín Departments (Peru); and H. youngi from Ecuador (Napo Province). A key to the known species of Hyogonia is provided.     

New species of Australopericoma Vaillant (Diptera: Psychodidae) from the Brazilian semiarid region and key to males of the genus

A key to males of Australopericoma and morphological remarks on Australopericoma caudata (Satchell) are also provided.     

Taxonomic status of Pseudosiphonops ptychodermis Taylor and Mimosiphonops vermiculatus Taylor (Amphibia: Gymnophiona: Caeciliaidae) with description of a new species

Pseudosiphonops ptychodermis Taylor is designated a junior synonym of Mimisiphonops vermiculatus Taylor, and Pseudosiphonops Taylor is designated a junior synonym of Mimosiphonops Taylor. A new species of Mimosiphonops is described and taxonomy of the genus reviewed. Relationships between Mimosiphonops and the closely related caecilian genera Siphonops and Lutkenotyphlus are discussed.     

Monstrilloids (Crustacea: Copepoda) from the Mediterranean Sea (Northern Adriatic Sea), with a description of six new species

Monstrilloid copepods collected during zooplankton surveys carried out over several years (2009–2016) in the Gulf of Trieste, northern Adriatic Sea, were examined. A total of seven species were found, of which six are undescribed, five of Cymbasoma and one of Monstrilla. These new species are described, illustrated and compared herein with its known congeners. Two of them are related to the C. rigidum species complex. One of these species is described based on both the male and the female; sexes were linked by identical details of the cephalic structure and the antennulary armature. Two previous reports of females attributed to C. tumorifrons from the Mediterranean relate to specimens that in fact belong to a new species, C. mediterranea. The most abundant species was M. grandis, which had a remarkable aggregation around the Trieste harbour in 2015. Male and female specimens of this assumedly widespread species were examined and the observed intra-specific morphological variability is reported and compared with previous illustrated reports; this nominal species probably this nominal species, probably represents a species complex. The addition of the new species here described brings the number of nominal species in the Mediterranean-Black Sea region to 26.
