Crotonia borbora

description: Borbora species-group
This is a new species-group, established to accommodate Crotonia sterigma sp. nov. and C. borbora Luxton, 1987, previously considered to be a member of the Capistrata species-group (cf. Colloff, 2009b for definitions of species-groups). The Borbora species-group differs from the Capistrata group (see below) in having greatly elongated setae c 1 and c 2 which originate on compound apophyses with bifurcating apices emerging from a single base. The caudal apophyseal cluster is on a stalk, the notogastral plate is narrow with parallel sides and the outline of the opisthosoma, delineated by the lateral margins of the notogastral shield, is lozenge-shaped. The anteriolateral part of the notogastral shield is waisted, and the prodorsum may be expanded posteriolaterally.

This is a new species group, established to accommodate Crotonia raveni sp. nov. The apophysis of setae f 1 are the longest of the caudal series, rather than those of h 2 or h 3, the lateral notogastral setae are elongated and flagelliform, and it has the full complement of setae in the c series. The apophyses of setae c 1-2 are long and cylindrical. The caudal apophyses are separated into two groups, with f 1 and h 1 positioned dorsally and h 2 and h 3 ventrally, rather than fused into one group. The broad strip of cuticle lateral of suprapleural scissure bears lyrifissures im and ip and the apophyses of setae e 2 and f 2.

Material examined. Holotype. Female (HNHM). Vietnam, Da Lat, Cam Ly area, moss sample from a fallen tree trunk in the rain-forest, 8 December 1994, S. Mahunka, Gy. Sziráki and L. Zombori coll.
Description. Female. Length of idiosoma 340 μm, width 270 μm (n=1). Shape circular, posterior margin rounded.
Dorsal idiosoma (Fig. 58). Marginal and dorsal shields fused. Dorsal setae marginally pilose. Dorsal idiosoma covered by small oval pits.
Ventral idiosoma (Fig. 59). Sternal and ventral shields without sculptural pattern. All sternal setae smooth and needle-like, St1 at mid-level of coxae II, ca 8 μm long, St2 at level of anterior margin of coxae III, ca 15 μm, St3 at level of posterior margin of coxae III, as long as St2, St4 at level of anterior margin of coxae IV, ca 8 μm long. Ventral setae smooth except V6 with one pair of lateral spines, V2 ca 9 μm long, V7 and ad ca 32–34 μm, V8 ca 20 μm long. V2 near posterior end of genital shield, V6 near edges of genital shield, V8 near fossula tarsales, setae ad situated on small protuberances lateral to anal opening, V7 placed between V8 and ad. One pair of lyrifissures situated near posterior area of coxae IV. Stigmata situated between coxae II and III. Peritremes hook-shaped. Genital shield narrow, long and subtriangular, surface covered by oval pits, its apical margin serrate. Base of tritosternum narrow, vase-like, tritosternal laciniae smooth, subdivided into two short lateral brances and one long central point (Fig. 60).
Gnathosoma (Fig. 60). Corniculi horn-like, internal malae short and smooth. Hypostomal setae h1 not clearly visible, h2 needle-like, ca 13 μm long, h3 and h4 smooth, needle-like, ca 10–11 µm long. Apical part of epistome marginally pilose. Chelicerae not clearly visible.
Etymology. The name of the new species is from the Latin word ‘scrobia’ and refers to the pitted surface of the dorsal idiosoma.
Remarks. The new species is known from the female holotype only and more collections are needed from the type locality, but the differences between the previously known and A. scrobia are enough to define it as new species. The shape of the genital shield of the female is similar to that of A. aokii (Hiramatsu), but the other Angulobaloghia species have different genital shield (Kontschán 2010b). The ventral shield is ornamented by oval pits in A. aokii, while the new species has a smooth ventral shield, V6 setae are smooth in A. aokii, but V6 with lateral spines in the new species.

description: The $^{19}$F$(p,γ)$$^{20}$Ne reaction is the only process to break out of the CNO cycle at temperature below 0.1 GK and may serve as the origin of calcium in first generation of stars after the Big Bang. In the recent measurement, the Jinping Underground Nuclear Experiment (JUNA) obtained the rate of $^{19}$F$(p,γ)$$^{20}$Ne reaction, significantly larger than the previously recommended values. In this work, we perform the theoretical studies of the $^{19}$F$(p,γ)$$^{20}$Ne reaction using the Gamow shell model in the coupled-channel representation (GSM-CC). At temperature around 0.1 GK, the predicted rate by GSM-CC is close to the rate found by JUNA. Thus, based on GSM-CC, the break-out reaction $^{19}$F$(p,γ)$$^{20}$Ne from the CNO-cycle might win over its competing reaction $^{19}$F$(p,α)$$^{16}$O, and produce enough calcium in the metal poor stars.

description: Dicerura yezoensis Jaschhof & Spungis sp. nov.
Figs 6–8
Diagnosis. Dicerura yezoensis, a member of the formosa group, is distinguished as follows: the gonostylus has a broadly rounded, not pointed, apex (Fig. 6, ↓1); the ventromedial gonocoxal processes are big and subglobular rather than ovate (Fig. 6, ↓2); and the posterior edge of the ninth tergite is provided with a pair of pointed, microtrichose lobes (Fig. 7, ↓3).
Other male characters. Body length 3.3 mm. Head. Eye bridge 3–4 ommatidia long dorsally. Antenna clearly
shorter than body; scape and pedicel yellowish, lighter than flagellum. Circumfila with 1, seldom 2 short
extensions. Neck of fourth flagellomere slightly shorter than node. Palpus 4-segmented, 0.7 times the head height.
Thorax. Scutum with dark stripes dorsally and laterally. Anepisternum with 10 setae. Wing as long as body, with
brownish tinge. Veins thick, distinct; Rs long, ¼ the length of R1, r-m slightly longer than Rs, apical portion of M1+2
distinct, basal portion vanished. Legs. Empodia rudimentary. Claws slightly bent, 4 basal teeth gradually
decreasing in size. Genitalia. Ninth tergite subtrapezoid, with setae of various lengths except along median;
anterior edge straight, faintly contoured (Fig. 7). Gonocoxites: ventral surface densely setose; ventral emargination broadly rounded, sclerotized basally; dorsolateral processes larger than ventromedial processes, both with fine setae; dorsal portions angular-shaped posteriorly; dorsal apodemes moderately long (Fig. 6). Gonostylus twice longer than broad, slightly bent, slightly tapered towards apex, large setae laterally, both small setae and dense, short microtrichia medially (Fig. 6). Tegminal apex with collar of 5 inconspicuous knobs (Fig. 8).
Etymology. The species epithet is derived from Yezo, a now historical name of Hokkaido, where the holotype of this species was collected.
Type material. Holotype. Male, Japan, Hokkaido, Tomakomai, Hokkaido University Experimental Forest, mixed broadleaf deciduous forest, 30 June–26 July 1999, Malaisetrap, M. & C. Jaschhof (in KUEC).

description: Dicerura barbata Mamaev, 1966
Figs 9–12
Dicerura barbata was previously known only from the original material, referred to by Mamaev (1966) as consisting of four males (including the holotype) and a female, from two separate localities in Ukraine. The morphological description in the same publication takes no account of the female; rather it is stated there that females of this species were unknown. We identified a male from northern Sweden as conspecific with D. barbata based on the genitalic drawing provided with the original description (Mamaev 1966: fig. 6.3).
Diagnosis. The gonocoxites of D. barbata are quite unlike that of all other Dicerura in having an extremely
large emargination ventrally, which leaves just a short, asetose intercoxal bridge; the emargination is partly filled with an ovate, microtrichose lobe (Fig. 11, ↓1). The large, subtriangular gonocoxal processes are densely microtrichose medially; the dorsal apodemes are conspicuously long and thin (Fig. 11, ↓2). The elongate gonostylus
has a small side lobe subapicomedially, which is covered apically and dorsally with dense, large microtrichia, a few setulae, and 1–2 short bristles (Fig. 10, ↓3). The apical fork of the ejaculatory apodeme is perfectly V-shaped (Fig.
12). The elongate, parallel-sided tegmen, which is membranous for the most part, has a broadly rounded apex and a single pair of small, sclerotized processes subapicolaterally (Fig. 12, ↓4). The apex of the ninth tergite is bilobed
and densely covered with short, thick microtrichia, especially along the edge and on the inside (Fig. 9).
Remarks. The only specimen of D. barbata examined here is remarkable for the presence of a distinct,
complete M1+2, a vein usually regarded as vestigial in Dicerura. Mamaev (1966) did not mention this vein in his
description of D. barbata.

description: Dicerura foliicola Mamaev, 1968
Figs 13–15
This Far East Russian species is known only from the type series, which consists of two specimens of each sex reared from larvae (Mamaev 1968). With a male body length of two millimeters, D. foliicola is one of the smaller species of Dicerura. The holotype male, which we studied here, is a pale, yellowish specimen with poorly contrasting genitalia; it is therefore possible that we missed inconspicuous substructures of the tegmen or ejaculatory apodeme.
Diagnosis. Characteristic of the gonocoxites is a rounded, asetose protrusion at the base of the ventral emargination, which has a glabrous border on either side (Fig. 13, ↓1). The medial gonocoxal bridges, which are
slightly protruding, are conspicuously densely setose. The gonostylus is characterized by the large medial lobe, which is strongly bulging (Fig. 13, ↓2), and the small, narrow apex, which is densely setose (Fig. 13, ↓3). The apical
fork of the ejaculatory apodeme consists of two lance-shaped rami, which are broader than in other species of Dicerura (Fig. 15, ↓4). The tegmen ends in a long, sharp point, which apparently is not an artifact of preparation
(Fig. 15). The ninth tergite, whose outline is broad-subtrapezoid, is very slightly concave and densely
microtrichose posteriorly (Fig. 14).
Material examined. Holotype male (specimen no. P-Di0137 in ZMUM), with the data as specified in the
original description (Mamaev 1968).

description: We use first-principle Quantum Monte-Carlo (QMC) simulations and numerical exact diagonalization to analyze the low-frequency charge carrier mobility within a simple tight-binding model of molecular organic semiconductors on a two-dimensional triangular lattice. These compounds feature transient localization, an unusual charge transport mechanism driven by dynamical disorder. The challenges of studying the transient localization of charge carriers in the low-frequency/long-time limit from first principles are discussed. We demonstrate that a combination of high-precision QMC data with prior estimates of frequency-dependent charge carrier mobility based on the static disorder approximation for phonon fields allows for improved estimates of mobility in the low-frequency limit. We also point out that a simple relaxation time approximation for charge mobility in organic semiconductors is not consistent with the QMC data. Physical similarities with charge transport in quark-gluon plasma are highlighted.

description: Dicerura stipator Mamaev, 1972
Figs 25–27
Dicerura stipator, another species found only in the Far East of Russia, is known from two males and one female, all mounted by Mamaev on one and the same microscope slide. Mamaev (1972) did not indicate which of the
males is to be regarded as the holotype, so both are referred to here as syntypes. The genitalia of both specimens are
partly distorted and collapsed, which is why the gonostylar structure cannot be described here. From what is left of
the gonostyli, we assume that their outline is similar to that in D. penttineni (Fig. 3). Mamaev’s (1972) original
description of D. stipator, which does not refer to characters of the female and lacks illustrations, is too unspecific
for the purpose of identification.
Diagnosis. Dicerura stipator is a typical member of the iridis group. It is the only species of Dicerura in which the two tines of the apical fork of the ejaculatory apodeme are serrate medially (Fig. 27, ↓1). Of the gonocoxites, the
ventral emargination is wide and shallow; the two pairs of processes bordering the emargination are approximately same size; the ventroposterior edge is broadly pigmented (Fig. 25, ↓2); and the dorsal portions are strongly bulging
medially. The tegmen of D. stipator, which is generally similar to that of D. penttineni (cf. Fig. 3), has a pair of small, sclerotized barbs and, behind the barbs, short appendages (Fig. 27, ↓3); its narrowly rounded apex is
reinforced by a roundish, sclerotized knob, which resembles the condition found in D. unidentata. The ninth tergite
of D. stipator is again similar to that of D. penttineni (cf. Fig. 4), but the narrow, apical portion, which is darkly
pigmented and provided with dense microtrichia on the inside, is larger (Fig. 26).
Material examined. Two syntype males, mounted on one and the same slide (no. P-Di0139 in ZMUM), with
the data as specified in the original description (Mamaev 1972).

Dicerura formosa

description: Dicerura formosa Mamaev, 1998
Figs 16–18
We identified our specimens from sketches made by one of us (MJ) while examining the holotype of D. formosa in 2012. Mamaev’s (1998) description of this species, whose only illustration was a schematic drawing of the gonostylus, is insufficient for specific identification. Dicerura formosa, described originally from southern Siberia, is newly reported here from two additional northern European countries.
Diagnosis. Characters to differentiate D. formosa from the other species of the formosa group are as follows.
The slightly bent gonostylus, whose apex is clearly tapered, bears large setae posteriorly and clearly smaller setae medially, the latter intermingled with short, dense microtrichia (Fig. 16, ↓1). The ventral gonocoxal emargination is
slightly convex basally, reinforced by sclerotization, and bordered by two pairs of gonocoxal processes, of which the ventromedial processes are ovate (Fig. 16, ↓2), while the dorsolateral processes are elongate and slightly bent (Fig. 16, ↓3). The semicircular collar of the tegmen has 5 inconspicuous, sclerotized knobs (Fig. 18). The ninth
tergite is unusual in two different aspects. First, the posterior edge has a small, broadly V-shaped incision (Fig. 17, ↓4) that is bordered on the inside by subtriangular, densely microtrichose protuberances, and second, the anterior edge is broadly rounded (convex) and reinforced by sclerotization, not straight and faint as in other Dicerura. Two non-genitalic characters uncommon in Dicerura, which were not mentioned in Mamaev’s (1998) description of D. formosa, are the presence of setae on the anepisternum and the long, sometimes even complete M1+2.

Dicerura unidentata

description: Dicerura unidentata Spungis, 1987
Figs 28–31
Spungis (1987) based his description of D. unidentata on three larvae found in Latvia, of which one developed into
a male adult. Subsequent records of males of this species are from Finland (Jaschhof et al. 2014) and, as shown
here, from Estonia, Slovakia, and Ukraine. The female of D. unidentata remains unknown.
Diagnosis. Dicerura unidentata is a typical member of the dentata group. Characteristic of the gonocoxites,
the ventral emargination is angular-shaped and bordered by small, inconspicuous protuberances with both setulae and large microtrichia (Fig. 28, ↓1); around the emargination is a darkly pigmented area. The subrectangular
tegmen is 2.5 times longer than broad and provided with 4–6 small barbs of various sizes apicolaterally (Fig. 31, ↓2). The additional, single barb present at the tegminal apex (therefore the species’s name, unidentata) is in most of the specimens studied here reduced to a roundish, sclerotized knob (Fig. 31, ↓3), in other specimens it is
untraceable. The subtriangular gonostylus is about 1.5 times longer than broad; the mediobasal lobe is somewhat
angular and provided with 5–15 short bristles among sparse, large microtrichia (Fig. 30). The apical fork of the
ejaculatory apodeme takes up more than one third of the apodeme’s total length (Fig. 31). The apex of the ninth tergite, which is broadly rounded to truncate, is covered with dense, thick microtrichia (Fig. 29, ↓4). Species with
similar genitalia are D. dentata and D. dispersa. In distinction from D. unidentata, the tegmen of D. dentata is provided with more and slightly larger barbs that together form a saw-blade structure on either side (Jaschhof & Jaschhof 2013: fig. 50E), while the tegmen of D. dispersa is constricted subapically, not parallel-sided (Jaschhof & Jaschhof 2013: fig. 51C).
Remark. Unlike stated by Spungis (1987), and in accordance with most Dicerura, the palpus of D. unidentata has four segments.

Dicerura iridis

Figs 22–24
Dicerura iridis, the most commonly found species of Dicerura in Europe, is redescribed here based on specimens
from Latvia (Spungis 1987).
Diagnosis. This is the only Dicerura in which the apices of the ejaculatory apodeme are not smooth but appear frayed (Fig. 24, ↓1), a detail discernible only at high magnification. Other characters of diagnostic merit are as
follows. The gonostylus, which is 2.5 times longer than wide, has a pointed, slightly bent apex and a long
mediobasal lobe that is only slightly protruding and provided with dense, large microtrichia, a few setulae, and 5–6
short bristles (Fig. 22). The gonocoxites have conspicuously few ventral setae; the ventral emargination is shallow and angular (Fig. 22, ↓2); the two pairs of processes bordering the emargination are same size, rounded, and
provided with both microtrichia and fine setae; the dorsal portions are angular-shaped posteriorly; and the dorsal apodemes are conspicuously long and thin (Fig. 22, ↓3). The apical portion of the tegmen, whose outline is
basically semicircular, is truncate to slightly concave on the crest and provided with 4–5 inconspicuous barbs on either side (Fig. 24, ↓4). The bilobed apex of the ninth tergite is covered with dense, thick microtrichia, especially
along the posterior edge and on the inside (Fig. 23).
Material examined. Latvia: 3 males, Sigulda, 20 May 1978, V. Spungis (in IBUL).

Dicerura scirpicola

description: Dicerura scirpicola Kieffer, 1898
Dicerura scirpicola, the generic type, was described from France based on larvae and adults of both sexes (Kieffer 1898, 1899). According to Kieffer’s (1899) paper, which contains an illustration of the male genitalia (fig. 2), the following male characters could help to positively identify this species: the color of the body is generally yellow without dark markings on thorax and abdomen; the ninth tergite is bilobed posteriorly; the gonostylus is almost three times longer than wide, bent slightly inwards, and provided with a small, slightly protruding lobe mediobasally; and the apical fork of the ejaculatory apodeme is strongly diverging. The latter character in particular might be specific to D. scirpicola. We suppose that this species is a member of the iridis group. Kieffer (1898, 1899) described larvae of D. scirpicola as living under the leaf sheaths of wood club-rush Scirpus silvaticus L. Prompted by that information, one of us (VS) investigated Latvian stands of S. silvaticus for larvae of D. scirpicola, which did not produce the anticipated result but brought forth the discovery of D. unidentata, whose larvae were found to live in the same microhabitat (Spungis 1987).

description: Dicerura infundibularis Fedotova & Sidorenko, 2005
This is another species described from a single male from the Russian Far East. Fedotova & Sidorenko’s (2005) description is confusing, for the wording does not always correspond with the illustrations, and illustrations are not consistent with one another. What is clear is that D. infundibularis is another species with a lobed gonostylus and a furcate ejaculatory apodeme. The gonocoxites have a broad, darkly pigmented margin ventroposteriorly, a not so common character in Dicerura. It is likely that D. infundibularis is a member of the iridis group.

description: Dicerura divaricata Fedotova, 2004
This species is known from a single male collected in the Far East of Russia. From Fedotova’s (2004) illustrations it is obvious that the genitalia of this specimen are strongly distorted, so that details of their structure remain obscure. There is no doubt that the gonostylus has a distinct basomedial lobe and the ejaculatory apodeme a furcate apex, but those characters do not distinguish D. divaricata from many other Dicerura. Fedotova’s (2004: fig. 320.3) illustration of the tegmen of D. divaricata suggests that this species might belong to the iridis group. One is left with the hope that fresh specimens will be found that can be assigned to this species and serve to describe its specific traits.

description: The Pegomya fulgens species group
This species group includes only two morphologically poorly differentiated species, Pegomya fulgens (Meigen) and P. transgressa (Zetterstedt), one western Palearctic, the other boreal Holarctic in distribution. P. transgressa is an exclusively northern species replacing P. fulgens in the subarctic and low arctic parts of Fennoscandia. Surprisingly, the only species found in Iceland is P. fulgens, which suggests that it has been accidentally introduced there.
Species of the Pegomya fulgens species group may in both sexes be separated from the very similar species of the Pegomya furva species group by the slightly longer aristal pubescence; males further differ by the different structure of male sternite V lobes (Figs 11, 12) and the presence of a pv seta on middle third of hind femur; females further differ by the non-expanded tips of the dense ventral sensilla on the mid and hind tarsi, and by the longer oviscapt (Fig. 64). Females as a rule with the pair of interfrontal setae fully developed.
