Termites live in a pear-shaped world: a response to Platnick

The six primarily Neotropical species groups of the genus Rachispoda are revised, comprising a total of 50 species, of which 35 are newly described. The aequipilosa group comprises nine species in the Neotropical and southeastern Nearctic regions: R. aequipilosa (Duda) comb. n., R. spuleri (Sabrosky) comb. n., and the new species R. alces, R. chisholmae, R. intonsa, R. joycei, R. laureata, R. luciana, and R. paludicola. The divergens group comprises ten Neotropical species: R. decimsetosa (Richards) comb. n., R. divergens (Duda) comb. n., R. multisetosa (Duda) comb. n., R. pluriseta (Duda) comb. n., and the new species R. condyla, R. forficula, R. luisi, R. merga, R. thaliathrix, and R. villosa. The fuscinervis group is a Neotropical and southern Nearctic group of 21 species: R. fuscinervis (Malloch) comb. n., R. schildi (Spuler) comb. n., R. striata (Duda) comb. n., R. trigonata (Spuler) comb. n., R. trochanterata (Malloch) comb n., and the new species R. aeditua, R. amarilla, R. andina, R. cesta, R. clivicola, R. colombiana, R. geneiates, R. justini, R. luminosa, R. meringoterga, R. oreadis, R. recavisterna, R. synoria, R. thermastris, R. trichopyga, and R. zygolepis. The maculinea group comprises seven Neotropical species: R. maculinea (Richards) comb. n., and the new species R. altimontana, R. baezensis, R. caesia, R. kaieteurana, R. lucaris, and R. praealta. The marginalis group contains the single Neotropical species R. marginalis (Malloch) comb. n. The m-nigrum group contains two species in the Neotropical and southeastern Nearctic regions: R. bipilosa (Duda) comb. n. and R. m-nigrum (Malloch) comb. n. Six described species are newly synonymized: Leptocera ensenada Richards (=R. divergens), L. limbinervis Duda and L. ruficornis Duda (=R. fuscinervis), L. paraguayensis Duda and L. weemsi Sabrosky (=R. m-nigrum), and L. rossi Richards (=R. multisetosa).     

The haemoproteids of the Old World avian families Alaudidae (larks), Irenidae (leaf birds), and Motacillidae (wagtails and pipits)

The haemoproteids of the Old World passeriform families Alaudidae, Irenidae and Motacillidae are reviewed. Haemoproteus alaudae Celli and Sanfelice, 1891 of the Alaudidae and H. aegithinae de Mello, 1937 of the Irenidae are re-described and neohapantotypes designated. Haemoproteus anthi de Mello, 1937 from the Motacillidae is re-described and H. motacillae n. sp. is also described from this family.     

A new species of Didogobius (Teleostei: Gobiidae) from the Adriatic Sea

Didogobius schlieweni sp. nov. is described from a single specimen collected among pebbles in shallow water at Unije island, near Cres, in the northern Adriatic Sea. The holotype has vivid dark and pale patterning, and is assigned to Didogobius on the basis of head neuromast patterns and meristic features. Diagnostic values of the latter are D2 I/12, A I/11, P 17, and LL 55–56. A key to species of the Chromogobius and Didogobius complex is provided.     

Systematics and fossil evidence of host-parasitoid relationships of Calamiscus Borgmeier (Diptera: Phoridae)

The life history and hitherto unknown males of Calamiscus cryptopalpis are described. A second species of this genus, C. inflativenis n. sp. is described from Costa Rica. The species C. cryptopalpis is a gregarious parasitoid of injured stingless bees in Costa Rica. The co-occurrence of a specimen of the genus Calamiscus in a piece of amber with the oldest known fossil bee is hypothesized to be the most ancient host-parasitoid relationship between a pair of insect species documented thus far. The otherwise rarely-seen fly was probably lured to the amber site by the alarm pheromones of the bee, and then trapped in the sticky tree resins.     

The aberrant and monotypic soft coral genus Malacacanthus Thomson, 1910 (Octocorallia: Alcyoniidae) endemic to southern Africa

The monotypic soft coral genus Malacacanthus has recently been rediscovered by means of scuba and is shown to be locally common and endemic in the shallow sublittoral of South Africa. Malacacanthus capensis (Hickson, 1900) is shown to be the proper taxonomic designation for the species. This species has previously been a problematic one due to the possession of several unusual morphological characteristics, including the total lack of sclerites and possession of a tough horny cuticle covering the stalk. The taxon is here shown to belong in the family Alcyoniidae by the possession of a full complement of mesenterial filaments, and not to the family Xeniidae as assigned by several previous authors. The species is here redescribed and the systematic status is revised. New observations on ecology and natural history from living colonies are also included.     

Eustigmaeus floridensis sp. nov., a new mite species of the genus Eustigmaeus Berlese, 1910 (Acari: Stigmaeidae) from citrus in Florida

Eustigmaeus floridensis sp. nov. is described and illustrated based on female specimens collected from citrus trees in Florida, USA. The new species is closely related to Eustigmaeus arcuata, Eustigmaeus segnis and Eustigmaeus microsegnis, all known to occur in Florida. Eustigmaeus floridensis sp. nov. can be distinguished by larger dimples associated with setae sce, d₂ and e₁ containing at least four or more vacuoles centrally; dorsal body setae broadly lanceolate and feather-like, except c₂, which is slender; anogenital area with striae and one pair of serrated aggenital (ag1) and three pairs of serrated pseudanal (ps_1?3) setae. A key to the Eustigmaeus species known to occur across USA is also provided.     

Contribution to the systematic revision of the African cyprinid fish genus Labeo: species from the Lower Zaire river system

The species of the genus Labeo from the Lower Zaire river system have been revised on the basis of 284 preserved fishes, including type material of 18 nominal species cited or described from this region. Morphometrics, meristic counts, morphological observations and radiographs have been used for this study. All results obtained are supported by statistical analyses. From the 18 nominal species reported, only 12 species are recognized as valid. Two major groups were identified: one group has rows of conical papillae on the inner surface of lips; and the other group presents rows of transverse plicae on the inner surface of lips. The first group has two species: L. lineatus and L. weeksii. One synonymy is proposed: L. lineatus (partim) = L. weeksii. In the second group, 10 species have been identified: L. longipinnis, L. degeni, L. barbatus, L. macrostoma, L. falcipinnis, L. cyclorhynchus, L. parvus, L. greenii, L. nasus and L. sorex. One unidentified taxon apparently represents a species new to science, but this must be confirmed by a wider revision of the genus which is the subject of further research. Some synonymies in this group are proposed: L. brichardi (partim) = L. barbatus; L. lineatus (partim) = L. degeni. Other synonymies already established by Reid (1985), have been confirmed: L. lividus = L. barbatus; L. brichardi (partim) = L. macrostoma; L. variegatus = L. cyclorhynchus. One synonymy has been restored: L. velifer = L. longipinnis. Finally, one synonymy remains in question: L. chariensis = L. parvus. A key to species is provided.
