(Mexico, Panama) and T. phobos Dantas, Giłka et Andersen, sp. nov. (Peru). Small adult males having wings with a high venarum ratio, unpaired tibial spurs on mid and hind legs, a hypopygial anal point lanceolate without spinulae or bars, a digitus with a well-developed basal tubercle bearing a long seta, a stout median volsella, and a gonostylus distinctly shorter than the gonocoxite, are a set of characters common to the two close species for which a new group is here proposed.

A total of 110 species of Chironomidae are known for Mexico: 52 species in 25 genera belong to the subfamily Chironominae, 30 species in 13 genera to Orthocladiinae, 21 species in nine genera to Tanypodinae, five species in two genera to Telmatogetoninae, and two species in one genus to Diamesinae. In addition, 41 genera without identified species are listed. The highest number of species (29) is recorded from the state of Campeche, while 19 species have been found in Veracruz and 15 in Nuevo León. Few or no records exist for states in Central and Northern Mexico, or those on the Pacific coast. The type localities for 34 species are in Mexico; of these, 27 species (25% of the total number of species recorded in the country) are endemic. Twenty-nine species recorded in Mexico have a Neotropical distribution, 15 a Nearctic distribution, and 39 species are distributed in both the Neotropical and Nearctic regions or more widely. It has been suggested that as many as 1000 species might occur in Mexico; so only a little more than 10% of the expected diversity has so far been recorded.

However, the specimen from Sabah was collected in a special study of rainforest canopy fauna (M. Spies pers. comm.). Wang & Saether (1998) used two variant original spellings of the genus name: Qiniella and Quiniella. Wang (2000), in his checklist of Chinese chironomids, spelled the name Qiniella, and has thus selected the correct original spelling according to Article 24.2.4 of the Code of Zoological Nomenclature (International Commission on Zoological Nomenclature, 1999).

The new species can be separated from its only congener, P. setosus Sublette & Wirth, 1972 from Jamaica, as it is slightly smaller with about 115 dorsocentrals compared to 56 in P. setosus. The inferior volsella is broadly subtriangular, while more lingulate in P. setosus, and the gonostylus has a small, but distinct megaseta and a subapical brush of spine-like seta, which apparently lack in P. setosus. The generic diagnosis is emended including the new species, and the systematic position is briefly discussed.

The 4 previously described species are redescribed and illustrated: T. aethiopica Kimmins, 1963a (Ethiopia), T. brunnea (Ulmer, 1905) (Indonesia), T. fletcheri Kimmins, 1963b (India), and T. sisyroides Banks, 1913 (Indonesia, Philippines). A related new genus, Fernandoschmidia, new genus, and 2 new species, F. amudita, new species, and F. aramaniya, new species, from India are described and illustrated. The phylogenetic position of the new genus is assessed; it is sister to a clade formed by Tagalopsyche and Mystacides Berthold, 1827, the only other genus in the Mystacidini.

Two new Triaenodes McLachlan species belonging to subgenus Triaenodella Mosely, T. akosua sp. n. ... more Two new Triaenodes McLachlan species belonging to subgenus Triaenodella Mosely, T. akosua sp. n. and T. amma sp. n., are described and figured, and four previously described species, T. dolobratus Gibbs, T. ghana Kimmins, T. proszynskii (Marlier & Botosaneanu), and T. serratus Ulmer are redescribed and figured based on males collected in Ghana. The female of T. proszynskii as well as the female holotype of T. palpalis Banks from Cameroon are also redescribed and figured. Further, an additional new species, T. kwadwo sp. n., from Ghana is described and figured; this species does not readily fit into any subgenus. A key to the subgenera of West African Triaenodes males and a key to the males of subgenus Triaenodella are provided.

Neomaruina ghanae n. sp. is described and illustrated based on an adult male specimen from Boti falls in Ghana. Neomaruina usambarica Wagner and Andersen, 2007 is redescribed and illustrated based on type and new material, in order to supplement the original description and to document variation in shape of gonostyli. A key to adults of all described Neomaruina species is presented, and the distribution of the genus within the Afrotropical region is discussed.

New records of thirteen Neotropical Nilothauma species are given and a key to the males of all known species of Nilothauma is provided.
