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.

The species described below is closely related to Dolichopus dorycerus Loew, 1864, but differs in both sexes in the colour of the lower orbital cilia and, in the male, in many details of the secondary sexual characters.Dolichopus phyllocerus, new speciesMale.–Length 6.3 mm.; wing length 6.2 mm. Face long, narrow, slightly broadened above, pale golden-brown, silvery below. Front metallic copper or coppery-green. Antenna (Fig. 1b) with first two segments yellow, the third black with about basal third yelllow; first segment of normal length; second very short, especially on lateral surface where it is scarcely visible; third short, broad, blunt. Arista black, about 21/2 times as long as rest of antenna, very slender, with a broad, blunt apical lamella. Lateral and lower orbital cilia yellow, upper cilia black.

Secondary Sexual

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.

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.

Junewangia aquatica sp. nov., a new Acrodictys-like fungus was collected on submerged wood from freshwater habitats in Yunnan Province, China. J. aquatica is characterized by its flared conidiophores with percurrent proliferations, monoblastic, terminal or intercalary, cylindrical conidiogenous cells, and subglobose to broadly ellipsoidal conidia with transverse and oblique septa. A phylogenetic tree of Acrodictys-like species was inferred from multi-locus (SSU, ITS and LSU) sequences. A key to the species of Junewangia is provided.

Abstract A new species of freshwater crab of the genus Teretamon Yeo & Ng, 2007, Teretamon husicum sp. nov., is described here from Husa Town, Longchuan County, Dehong Prefecture, Yunnan Province, China. Teretamon husicum sp. nov. can be distinguished from other species by a suite of morphological characters, including a bilobed frontal margin, smooth posterolateral regions, and a broadly rounded dorsal flap on the G1 terminal segment. An updated identification key for the species of the genus Teretamon is provided.

A New Species

Habenaria luquanensis from Yunnan Province is described and illustrated. This new species most closely resembles H. delavayi in having a basal leaf rosette, flowers with a concave and abaxially keeled dorsal sepal and linear petals. It is distinguished by herbaceous, loosely arranged rosette leaves (versus tightly adpressed to each other), a lip which is 3-lobed only to 1/3–1/4 from the base and has narrowly oblong lateral lobes (versus deeply 3-lobed nearly to the base with linear-cuneate lateral lobes). Another similar species is H. finetiana, but this species can be distinguished by its cauline leaves, longer floral bracts, petals forming a hood with the dorsal sepal, a lip which is 3-lobed only in the upper half and  rhombic, serrate lateral lobes, a spur which is nearly as long as the ovary, and central rostellum lobe not clearly visible.
