No full textPolypedilum paranubifer Cranston sp. n. (Figs 1D, G; 2B, 2E, 3E) urn:lsid:zoobank.org:act:063C158B-3D62-4A56-9F52-AD5F84204456 Type material. Holotype: Le /P ♂, AUSTRALIA: Northern Territory, Ranger Uranium mine, retention pond 2, 12°41’S 132°55'E, 31.v.1988 (Cranston) (ANIC). Paratypes: Le/P♀, as holotype, except retention pond 1, 15.v.1992; 4♂, as holotype (ANIC); 11♂, Ranger Uranium mine, Retention pond 4, light trap,. v.1988 (Wells & Suter) (ANIC, 2 to BMNH). Other material examined: 4L, Northern Territory, Ranger Uranium mine, Retention Pond 1, 31.v.1988 (Cranston) (ANIC). Description as for P. nubifer, except as follows. Adults (Figs 1D, G, 2B; female from pharate only). For mensural features see Table 1. Both sexes differ from P. nubifer in non-overlapping ranges of fewer setae on wing veins R and R1 and in the complete absence of setae on R4+5. Tergite VIII anteriorly appearing tapered to connection with T VII (Fig. 1D). Male genitalia (Fig. 1G) with gonocoxite weakly bulging, connected to gonostylus by pale membranous area. Dorsolateral seta present on a superior volsella otherwise similar in shape to that in P. nubifer. Gonostylus broad without bilobed apex, distally rounded. Female genitalia: gonapophysis VIII with dorsolateral lobe scarcely developed; ventrolateral lobe welldeveloped, 55 µm long, highly setose, with apical setae directed mesad (Fig. 2B). Cerci 100 x 100 µm, rounded rectangular. Pupa (Figs 2E, 3E). Exuviae 5.4–5.8 mm long, pale with yellowish highlights and yellow-brown posterolateral comb on abdominal segment VIII. Cephalic tubercles conical, 50 µm high and 100 µm wide at base, bearing 35–45 µm long frontal seta inserted subapically on narrowed apical spine or ‘nipple’ of tubercle. Hook row on II c. 58– 64% of tergite width, with c. 44–45 hooklets. Spinule pattern apparently as in P. nubifer (Fig. 3B). Caudolateral ‘comb’ on VIII ((Figs 2E, 3E) with 2–3 stronger spines, none dominant; 2–5 smaller subsidiary spines, not extending to L4 setal base. Anal lobe fringe uneven, uniserial, with 47–50 taeniae, without dorsal seta. Larva. All measurements and ratios fall within the corresponding ranges for P. nubifer (see Table 2). Microsculpture of ventromental plates as in P. nubifer. Notes. Adult males of P. paranubifer consistently differ from P. nubifer in the presence of a dorsolateral seta on the superior volsella. By itself, this difference could be seen as no more than population level variation, but it is accompanied by a suite of mensural differences in wing setation (Table 1). The pupa seems identical to P. nubifer except for the smaller size and slightly different structure of the ‘comb’ on the posterolateral corner of segment VIII. The latter, however, varies even within ‘true’ P. nubifer, thus probably is unreliable for discrimination. Likewise, the larvae of P. paranubifer cannot be distinguished from those of P. nubifer on morphology. Unreared larvae from retention pond 1, although seemingly identical with those associated by rearing with P. paranubifer adults, cannot be included in the type series since one pupal exuviae clearly belonging to P. nubifer was found also from the same pond system.Published as part of Cranston, Peter S., Martin, Jon & Spies, Martin, 2016, Cryptic species in the nuisance midge Polypedilum nubifer (Skuse) (Diptera: Chironomidae) and the status of Tripedilum Kieffer, pp. 429-447 in Zootaxa 4079 (4) on pages 439-440, DOI: 10.11646/zootaxa.4079.4.3, http://zenodo.org/record/105086

Nubensia Spies, n. gen.
No full text<i>Nubensia</i> Spies n. gen. <p> <b>Etymology.</b> Edwards (1929) named <i>Pentapedilum nubens</i> in view of the cloudy areas on the wing (the Latin verb form <i>nubens</i> translates to clouding, veiling). The new genus name reminiscent of the long established species epithet is intended to help recall which taxon is meant among many others, but also to reflect that the true relations of the animals the name denotes have been curiously veiled. For the purposes of nomenclature, the gender of the genus name is feminine.</p> <p> <b>Species included.</b> Type species (original combination): <i>Pentapedilum (Pentapedilum) nubens</i> Edwards, 1929. No congeneric species is known at this time.</p> <p> <b>Differential diagnoses.</b> Adult males in <i>Nubensia</i> are considered as distinguished from those of other Chironomini by the following combination of characters. Antenna with (normally) 13 flagellomeres; wing extensively setose on many cells and veins, and with a pattern of darkened areas; fore tibia with one scale elongate but without spinose projection; antepronotal lobes reaching near anterior end of scutum but dorsally narrowed and separated; superior volsella with small transverse, setose base and long, strong and bare digitiform part; gonostylus medially with field of moderately long and strong setae, without row of long and fine setae. Single members of <i>Phaenopsectra</i> or <i>Sergentia</i> may share many but not all of these features, especially not the patterned wing.</p> <p> Many adult females in genera of the <i>Endochironomus</i> complex, in <i>Phaenopsectra</i> or <i>Polypedilum</i> —to which <i>Nubensia</i> may be related—are known insufficiently or not at all; therefore, attempts to separate them at genus level seem premature. However, the thorax, wing and leg characters discussed above for the male of <i>Nubensia nubens</i> in combination with genitalia as characterized in the species description below appear to be unique at this time.</p> <p> The pupa cannot be diagnosed simply among other Chironomini with relatively few branches to the thoracic horn and with abdominal tergite armament characterized by anterior transverse point rows. However, <i>Nubensia</i> appears distinguished by the absence of spinules around the frontal setae in combination with the abdominal pattern described below—notably the presence of conjunctive armament (<i>i.e.</i>, an apical band sensu Langton & Visser 2003) on IV/V only, and the relatively few and short taeniae in the anal lobe fringe.</p> <p>The larva stands out from all known Chironomini by the mentum teeth proportions combined with the absence of a labral lamella and the separation between clypeal sclerite and frontal apotome.</p>Published as part of <i>Spies, Martin & Dettinger-Klemm, Andreas, 2015, Diagnoses for Nubensia, n. gen.
