A new and very unusual species of green lacewings, Ungla pseudomeleoma sp. nov. is described from Peru. Males of this species exhibit a remarkable example of generic-level homoplasy with Meleoma. Its abdominal and genitalic features are completely consistent with the genus Ungla. However, its external sexually dimorphic features resemble those of both Ungla and Meleoma. Females of the new species also express cranial modifications that resemble those of some female Meleoma species.

A new species Sybistroma genriki sp. n. from the Yunnan province of China is described. It belongs to S. incisa group of species, differing from other species in mostly yellow antenna with arista-like stylus much longer than postpedicel; postpedicel elongated, much longer than wide, acute apically; stylus apical, with dark and white apical swelling; lower postocular setae white; legs mostly yellow except mostly black mid and hind coxae and brown-black distal spot on hind femur. A key to 11 species from Sichuan and Yunnan is provided, based mainly on male secondary sexual characters. The known distribution of the dolichopodine genus Sybistroma Meigen, 1824, is briefly discussed.

Recently, the author described two species of the genus Hoplosaenidea Laboissiere, 1933 (Coleoptera: Chrysomelidae: Galerucinae) where the male having a peculiar secondary sexual characters: clypeus excavated, furnished with projections, and the antennal first segment large, broadened, excavated and spined at apex. The two species are H. takizawai Mohamedsaid, 2001 (Fig. 5) and H. singaporensis Mohamedsaid, 2002 (Fig. 6) described from Bali and Singapore, respectively. The presence of secondary sexual characters in males is most prevalent in the chrysomelid beetles of the subfamily Galerucinae (Mohamedsaid 2004b).

A new species of ciid beetle from southwestern South Africa is described. Images of the habitus, male genitalia and other characters of the external morphology are provided. The observed variations of male secondary sexual characters are briefly discussed. The similarities of external morphological characters of Cis pickeri sp. nov. to other species of Cis Latreille are discussed, and the new species is tentatively included in the bilamellatus species group.

The spoon tarsus species subgroup is revised and this clade is placed in the modified tarsus group of Hawaiian Drosophila. The species boundaries in this group are discussed in light of diagnostic secondary sexual characters of males. Drosophila septuosa Hardy is regarded as a junior synonym of Drosophila percnosoma Hardy. A new species, Drosophila kikalaeleele Lapoint, Magnacca & O’Grady is described. Drosophila fastigata Hardy, a species endemic to O‘ahu, is added to the species subgroup, bringing the total number of known species to 12. An updated key to species is provided to the spoon tarsus subgroup.

Pareiorhaphis nasuta, a new neoplecostomine catfish of the family Loricariidae is described. The species was collected from headwaters of the rio Matipó, tributary of the upper rio Doce basin in State of Minas Gerais, Brazil. The new species is readily diagnosed from all remaining congeners by the longer snout and by the smaller orbital diameter. The new species is the first representative of the genus Pareiorhaphis discovered in the rio Doce basin, thus expanding its geographic distribution. A phylogenetic diagnosis for Pareiorhaphis is presented.

Male Genital

A wasp mimicking praying mantis (Mantodea) of the early evolving Mantoididae family was discovered in 2013 at a research station near the Amazon River in Northern Peru. This adult specimen exhibited a striking bright red/orange and black coloration pattern that was undocumented in all known praying mantis species. We tested the status of this new specimen using external morphology, male genital dissections, and geographic distribution. Our findings demonstrate the specimen to represent a new species, Vespamantoida wherleyi gen. nov. sp. nov., that is closely allied with a recently described species, Mantoida toulgoeti Roy, 2010, both of which are included within the newly erected genus. To support our actions, we present high resolution images of museum preserved and living specimens, morphological illustrations, a generic-level distribution map, and recorded video of the behavior of the holotype taken in the field at the time of collection. The bright red/orange coloration contrasted with black markings, the general appearance of a hymenopteran that includes a narrowed wasp waist, and the locomotory patterns and antennal movements mark this newly discovered species as unique among all hymenopteran mimicking Mantoididae as well as all other praying mantises.

A New Species

A new species of metacrangonyctid amphipod crustacean is described from the Salalah coastal plain aquifer in south-western Oman. This is the easternmost record of the group, with representatives previously thought to span from Hispaniola in the Caribbean to the Sinai Peninsula in Egypt. Metacrangonyx dhofarensis sp. nov. is unique among metacrangonyctids in the display of a sexually dimorphic armature on pereiopod IV. In addition, its hypertrophied coxal plate IV, reduced plates I-III, coxal plate VII lacking anteroventral lobe, and telson longer than broad are also distinctive. The same holds for the proximal segment of peduncle of antennule, provided with two hypertrophied robust setae on dorsolateral margin. The mandibles of the new species are devoid of palp, a feature shared only with Metacrangonyx antennatus Messouli, El Alami, Coineau & Boutin, 2008. The presence of metacrangonyctids on the coasts of the Arabian Peninsula is probably the result of a vicariant event rather than of an episode of trans-Arabian continental dispersal by a Middle East ancestor. This is in accord with the presumed marine origin of the family and with the existence of a shallow water marine continuum between the current south-western Omani coast and the peri-Mediterranean area -where most species of metacrangonyctids are located - until approximately 16 Ma.
