The final stadium larva of Megalestes heros Needham, 1930 is redescribed and illustrated in detail. It is characterized by having a long and cylindrical body, a very long prementum with two end hooks of unequal size on lateral lobe, parallel wing sheaths, long and slender legs, female ovipositor short reaching the basal third of S10, and based on a distinct abdominal color pattern. The major diagnostic characters of the larvae of the genus Megalestes are as follows: (1) body smooth and slender, with long abdomen and leaf-shaped caudal gills; (2) antenna filiform, seven-segmented,third segment longest; (3) median cleft present in median lobe of prementum; lateral lobe with two end hooks of unequal size, the inner one being longer and larger than the outer, movable hook without setae; (4) wing sheaths parallel to each other.

Two new species of Diplura C. L. Koch 1850 are described from Brazil: Dipluramapinguari sp. n., from the state of Rondônia in southeastern Amazonia, northern Brazil, and Diplurarodrigoi sp. n., known from southeastern and central west regions of Brazil. Diplurarodrigoi sp. n. is morphologically similar to D.lineata (Lucas, 1857), D.sanguinea (F. O. Pickard-Cambridge, 1896), and D.mapinguari sp. n. Comments on diagnostic characters of Diplura are included. The synonymy of D.maculata (Mello-Leitão, 1927) with D.catharinensis (Mello-Leitão, 1923) is corroborated. A classification of color pattern of the dorsum of the abdomen is given.

A new species of the genus Hydaticus Leach, 1817, subgenus Prodaticus Sharp, 1882 (Coleoptera: Dytiscidae) has been discovered in the mountains of Cerros del Sira, Peru. It is here described as Hydaticus (Prodaticus) hauthi sp. nov.. It is morphologically similar to the Peruvian H. panguana Megna, Balke, Apenborn & Hendrich, 2019. The new species differs from H. panguana by its almost complete black dorsal surface and the shape of the median lobe. Diagnostic characters of both species, including illustrations of male genitalia and habitus, are presented, and a modified key for the 12 Neotropical species is provided.

A New Species

Liolaemus dorbignyi is re-described, and its type locality restricted to the Sierra de Fiambalá, Catamarca Province, Argentina. Also, Liolaemus scrocchii sp. nov., a new species of Liolaemus belonging to the L. montanus series, previously confused with L. dorbignyi , is described. This new species inhabits the phytogeographic region of Puna in Argentina at 3500 m. and is distributed in Jujuy and northwestern Salta provinces. Diagnostic characters include the color pattern, (composed of transverse paravertebral spots, that are band shaped and never reach the lateral region, and never contact the vertebral zone), and the number of scales around midbody. Several populations from different localities were considered L. dorbignyi because of their color pattern and squamation. Even though part of this confusion is clarified in this contribution, some populations still require further study.

A New Species

A new species of Garra with a rostral proboscis is described from the Barak River drainage in Manipur, India. Garra paratrilobata, new species, is distinguished from its congeners in having the combination of the following characters: a prominent trilobed proboscis, the median lobe with 5–7 uni- to tricuspid tubercles on its anterior margin and 4–6 minute tubercles on its anteroventral margin; lateral lobe of the proboscis with 3–4 minute tubercles; lateral surface of the snout lobular, with 6–9 tubercles; 33–34 lateral-line scales; and the rostral surface concave, creased and depressed.

AbstractAtheta (Badura) ehnstroemi n.sp. is described from material collected in central and northern Sweden. The lectotype of A. macrocera (Thomson) is designated. A key to the known species of Badura is given. Their diagnostic characters and taxonomic relationship to each other is discussed. Species of Badura can easily be distinguished by the shape of median lobe and copulatory piece of aedeagus but a number of other important characters are also mentioned. Ecological and distributional information is given for each species.

The Family

Notomicrus petrareptans sp. n. is described from an inselberg seepage in southwestern Suriname. This species is diagnosable by a combination of its weakly punctate elytra, respective shapes of the pro- and mesotarsal claws (males), and long and slender median lobe of the aedeagus. This is the first member of the subfamily Notomicrinae to be described from hygropetric seep habitats and only the second known seep-dwelling species of the family Noteridae. Diagnostic characters are illustrated and habitat images are provided.

Wing Coloration

In certain times of the year, Actinote butterflies can be vastly abundant in Southeastern Brazil, thus representing conspicuous denizens of our fauna. Their wing coloration allows for the recognition of five major patterns, which probably resulted from mimicry. Furthermore, examination of series of field-collected and reared specimens clearly demonstrates a high intra-specific variation in wing color pattern. In concert, inter-specific resemblance (mimicry) and intra-specific variation make it difficult to discriminate Actinote species from each other. This key aims at providing a tool for identification of male Actinote. To that effect, we provide diagnostic characters and illustrations of wings and male genitalia for 22 species. We hope that the clear identification of these species will lead to the discovery of species yet unrecognized in Southeastern Brazil.

Distinctive Cell

Salivary glands of female Aedes aegypti are made up basically of two lateral lobes consisting of proximal, intermediate, and distal portions, and a median lobe consisting of intermediate and distal portions. Branches occur in the lateral lobes and to a lesser extent in the median lobe, resulting in varying degrees of duplication of these portions. Each portion is composed of a distinctive cell type. The proximal and distal portion of the lateral lobe and the distal portion of the median lobe are glandular in function. Non-glandular intermediate portions of the lateral and median lobes have membrane developments similar to tissues functioning in water transport and thus may hydrate the dense secretory material of the distal portions of the salivary gland by the active secretion of water.

Diagnostic Characters

Genus Lepidocyrtus is represented by 25 species in Europe and the correct identification of some of them is difficult to achieve due to lack of diagnostic characters and some published errors description. In this paper I have studied specimens of Lepidocyrtus flexicollis, L. curvicollis, L. monseniensis and L. nigrescens and I have found several diagnostic characters very useful for their differentiation. The total chaetotaxy of fourth abdominal tergum is very informative for these four species and could be for the whole European species. I have consulted the literature that describes the European species and I made a diagnosis of all of them using the best diagnostic characters possible, with which I have elaborated an identification species key. The high chromatic variability of some European species makes the use of color pattern for taxonomy on this region problematic.
