Pseudeuophrys browningi (MILLIDGE & LOCKET, 1955) (Araneae: Salticidae) new to Germany and Enoplognatha caricis (FICKERT, 1876) (Araneae: Theridiidae) new to Brandenburg (Germany)

In den Jahren 1994, 1996 und 1997 wurden in Brandenburg zwei Spinnenarten gefunden, von denen sich eine Art als neu für die deutsche und eine neu für die brandenburgische Fauna erwies. Eine Nachbeschreibung der beiden Arten erfolgt an dieser Stelle nicht, da sich hervorragende Beschreibungen sowie Abbildungen der Genitalorgane bereits in den gängigen Bestimmungswerken (HEIMER & NENTWIG 1991, LOCKET et al. 1974 und ROBERTS 1995) befinden

Gill set is represented by gill I, III, V and VII (Figs. 42–45). Caudal filaments with whorls of small spines and narrow black to brown segments alternately (Fig. 41).</p> <p> <b>Etymology:</b> The name refers to the Nam Lang River, where the species has been found.</p> <p> <b>Diagnosis:</b> The new species is recognized by large brown patches in male forewings (Fig. 21) and by completely brown-tinged hind wings (Fig. 22); in both sexes contrasting with other <i>Compsoneuria</i> Eaton, 1881 species with merely cross veins brown shaded. The only species in having brownish-tinged hind wings is, according to Webb <i>et al</i>. (2006), the Javan <i>Compsoneuria lieftincki</i> (Ulmer, 1939). However, apart from other penial characters (Ulmer 1939: Fig. 164), legs are quite different due to four dark cross bars in each femur and lacking cross bars on the tibiae. The speckled patterns of head, body and legs in adults and larvae are very characteristic for genus <i>Compsoneuria</i> Eaton, 1881 (Braasch & Soldán 1986b; Sartori & Elouard 1996; Ulmer 1939), but difficult to use for separating species, because they are relatively similar among species but rather variable within species. Fortunately, the species are readily distinguished by differences in gill shape of full-grown larvae.</p> <p> <b>Biology:</b> Besides <i>Compsoneuria langensis</i>, a few male specimens of <i>C. thienemanni</i> (Ulmer, 1939) were found in the mountainous region of Soppong in 2001–2005. However, the latter species, although very abundant, was the only species in the larger rivers of lower altitudes, namely Mae Nam Ping and Mae Nam Chaem near Hot, Chiang Mai Province, in IV 2003, alt. ca 200 m, 18°12’07.54’’ N, 98°36’32.85’’ E. Both species are mainly found at floating water plants or even thick pads of green algae.</p> <p> <b>Material examined:</b> HOLOTYPE: male, Thailand, Mae Hong Son Province, Soppong, Nam Lang River, 19°34.447´N, 98°16.727´E, alt. 605 m; 03.–25.IV.03, at light (DB); PARATYPES: 11 males, 17 females, same locality, same time, at light (DB).</p> <p> <b>Further material:</b> 4 La, Soppong, Nam Lang, 03.–25.IV.03, botton sample (DB); 1 La, Nam Lang, 10 km below Soppong, same time, bottom sample (DB); 1 La, same region, Nam Khom River 19°21’N, 97°57’E, alt. ca 600 m, 08.IV.03, bottom sample (DB); 3 La, same region, near village Mena, right tributary of Mae Nam Pai River 19°26’N, 98°23’E, alt. ca 622 m; 25.IV.03, bottom sample (DB); 5 La, same region, Mae Nam Pai River, near village Pai 19°22’N, 98°26’E, alt. ca 622 m; 25.IV.03, bottom samples (DB).</p> <p> <b>Types deposition:</b> HOLOTYPE: <b>male</b> (<b>MNHU</b>, 70% alcohol); PARATYPES: 1 male, 1 female (<b>MNHU</b>); 2 males, 1 female (<b>SMF Eph</b>), 2 males, 2 females (<b>ZMKU</b>); males, females (<b>DBP</b>); some presumed La of species in collections as above.</p>Published as part of <i>Braasch, Dietrich & Boonsoong, Boonsatien, 2010, A contribution to the Heptageniidae (Insecta, Ephemeroptera) of Thailand and Malaysia, pp. 1-26 in Zootaxa 2610</i> on pages 7-11, DOI: <a href="http://zenodo.org/record/197793">10.5281/zenodo.197793</a&gt

Epeorus bifurcatus Braasch & Soldan 1979

<i>Epeorus bifurcatus</i> Braasch & Soldán, 1979 <p> <b>Material examined.</b> 1 La: Thailand, Tak Province, 16°30’ N, 99°00’ E, alt. ca 400 m, XI. 2008, leg. Freitag, Manila, det. Braasch).</p> <p> <b>Diagnosis.</b> <i>Epeorus bifurcatus</i> is a smaller species (length to 12 mm), recognizable by a pair of relatively short submedian spines on terga I–IX, flatly elliptical head (Nguyen & Bae, 2004a: p. 21, Figs. 7,9), posterior margins of terga with densely rowed blunt bristles, surface of terga with very fine scattered setae, only a weak fringe of small setae shorter than spines in the medial groove of terga and with triangular gill I of same length as following gills, all equally ovaloid, and femora with spot (Braasch & Soldán 1979: p.266, Figs. 15–22). Contrastingly, <i>E. rhithralis,</i> as well as <i>E. bifurcatus</i>, have ovaloid shape of head, long elliptic form of first gill, pointed bristles on posterior margins of terga and lack of groove on terga (Braasch 1980: p. 63, Figs. 4 b–l). Other species from the region are either without any spines as <i>Epeorus hieroglyphicus, E. khayengensis</i>, <i>E. papillatus</i>, <i>E. suspicatus</i>, <i>E. tiberius</i> Braasch & Soldán, 1984, or provided with pairs of tubercles like <i>E. rhithralis</i> or with pairs of long spines like <i>E. aculeatus</i>, <i>E. bispinosus</i> Braasch, 1980 and <i>Iron martensi</i>.</p> <p> <b>Discussion.</b> <i>Epeorus bifurcatus</i> is new for Thailand. To date this species is only known from Vietnam (Nguyen & Bae 2004a) and Thailand. Comments on its distribution are seen above under <i>Epeorus inthanonensis.</i> Adults and subadults are unknown.</p>Published as part of <i>Braasch, Dietrich & Boonsoong, Boonsatien, 2010, A contribution to the Heptageniidae (Insecta, Ephemeroptera) of Thailand and Malaysia, pp. 1-26 in Zootaxa 2610</i> on page 23, DOI: <a href="http://zenodo.org/record/197793">10.5281/zenodo.197793</a&gt

Heptageniidae (Insecta, Ephemeroptera) of Thailand

Nine genera and twenty-two species of heptageniid mayflies from Thailand are defined in this present work as well as one suggested further subgenus, Compsoneuria (Siamoneuria) kovaci (species “incertae sedis”) including some particular characters. Taxonomic remarks, diagnoses, line drawings of key characters, distribution, habitat and biological data, and a larval key to the genera and species are provided. The chorionic eggs of eight genera and eight species were observed and shown using a scanning electron microscope

Rhithrogeniella ornata Ulmer 1939

<i>Rhithrogeniella ornata</i> Ulmer, 1939 <p> <b>Material examined.</b> 5 SI males, Malaysia, Gombak River, Research-Station Senckenbergmuseum Frankfurt am Main, 16.– 20.08.2007, leg. D. Kovac, det. Braasch.</p> <p> <b>Diagnosis.</b> The longer male subimagos of <i>Rhithrogeniella ornata</i> (5.5-7.0 mm) can be separated from <i>R. tonkinensis</i> Soldán & Braasch, 1986 by: a pair of brown paramedian bands, and median streak cleft on terga II–VIII (Ulmer 1939: p. 577, Fig. 170), posterior margins of terga with broad darker rim, contiguous to the bands; figure mark on tergum VIII residuary, consisting merely of two median streaks of half tergum length and a cross-streak medio-distally; and terga IX–X light. In contrast to <i>R. ornata</i> from Java and Sumatra (Ulmer 1939), the median streak in the specimens from Malaysia is only faintly cleft and their pattern of tergum V is somewhat blurred or extinguished. The apices of penis are bluntly pointed, and the medial portion of posterior margin of subgenital plate is slightly concave. Ulmer (1939) illustrated the male (p. 577, Fig. 165–168) and described the female (text only) of <i>R. ornata</i>; the larva of this species remains unknown.</p> <p> In the smaller male subimagos of <i>R. tonkinensis</i> (4.1–4.7 mm) throu-going paramedian bands on terga II– VI, on V and VI shortened, median streaks on terga lacking, terga VII–X are light; apices of penis lobes broadly rounded; posterior margin of subgenital plate straight (Soldán & Braasch 1986: p.209, Fig. 19–20). Larvae, and larvae and imagos of <i>R. tonkinensis</i> are respectively figured in Soldán & Braasch (1986: p. 205, Figs. 1–8, p. 207, Figs. 9–12) and Braasch (1990: p.11, fig. 17.1–4).</p> <p> <b>Discussion.</b> The new findings in Malaysia only presented subimago males. Therefore comparison was made along corresponding figures in Soldán and Braasch (1986) and Ulmer (1939). Now, <i>Rhithrogeniella ornata</i> is known from Java, Sumatra and continental West-Malaysia, whereas <i>R. tonkinensis</i> is found in China, Thailand and Vietnam (Braasch 1990, Ulmer 1939, You <i>et al.</i> 1983). We have already previously pointed out (Braasch & Boonsoong 2009) that <i>R. tonkinensis</i> is probably identical with ‘ <i>Afronurus’ sangangensis</i> (You <i>et al.</i> 1982: p. 62, Figs. 1–13), but we had no opportunity to confirm this by comparing Chinese material.</p>Published as part of <i>Braasch, Dietrich & Boonsoong, Boonsatien, 2010, A contribution to the Heptageniidae (Insecta, Ephemeroptera) of Thailand and Malaysia, pp. 1-26 in Zootaxa 2610</i> on pages 23-24, DOI: <a href="http://zenodo.org/record/197793">10.5281/zenodo.197793</a&gt

Iron martinus Braasch & Soldan 1984

<i>Iron martinus</i> Braasch & Soldán, 1984 <p> <b>Material examined</b>. 5 La, Chiang Rai Province, Khun Kon Waterfall, 19°52’59.11’’N, 99°36’58.39’’E, alt. ca 800 m; II. 2004, leg. Braasch; DB.</p> <p> <b>Diagnosis.</b> <i>Iron martinus</i> is easily recognized among the few South-east Asian representatives of the genus (s. above) by having rhomboid head, pairs of moderately long spines on terga I–IX, large but narrow gill I forming a sucking disc, an unfolded gill VII and a dark femur spot (Braasch & Soldán 1984a: p. 113, Figs. 35–44; Nguyen & Bae 2004b: p. 103, Figs. 1–6). Femur spot present in Vietnamese specimens (Nguyen & Bae 2004b: p. 103, Fig. 2) as also proved by (Braasch & Soldán 1984: p. 111: ‘Auf den Femora Femurfleck’), and it is likewise present in specimens from Thailand.</p> <p> Second south-east Asian species of genus, <i>Iron longitibius</i> <b>sp. nov.</b> (s. above) differs from <i>I. martinus</i> by having rounded triangular head with anterior margin straight and slightly emarginated, spine-less terga, relatively long foretibiae (ca. 1.2 length of forefemora), gill I greatly extended, overlapping beneath abdomen and broadened anteriorly forming sucking disc, and gill VII elongated, curved downward, without fold. Comparison with other Asian <i>Iron</i> -species is presented under foregoing <i>Iron longitibius.</i></p>Published as part of <i>Braasch, Dietrich & Boonsoong, Boonsatien, 2010, A contribution to the Heptageniidae (Insecta, Ephemeroptera) of Thailand and Malaysia, pp. 1-26 in Zootaxa 2610</i> on page 23, DOI: <a href="http://zenodo.org/record/197793">10.5281/zenodo.197793</a&gt

Epeorus nguyenbaeorum Braasch and Boonsoong, sp. nov.

<i>Epeorus nguyenbaeorum</i> Braasch and Boonsoong sp. nov. <p> This species was figured by Nguyen and Bae (2004) as <i>Epeorus hieroglyphicus</i> Braasch & Soldán, 1984, from Vietnam. Prof. Dr. Bae, being corresponding author, was informed by personal communication (Braasch, 15.IX.2004) about the misinterpretation of the species in question, of which he has given kindly acknowledgement (Bae, 30.IX.2004 personal communication). In honour of Dr. Van Vhin Nguyen as discoverer of the new species and Prof. Dr. Yoon Jae Bae as his adviser and co-author, we name the new species <i>Epeorus nguyenbaeorum</i> <b>sp. nov.</b></p> <p> <b>Material:</b> HOLOTYPE: <b>Female La</b> (Figs. 19–24), Vietnam, Ha Giang Prov., Vi Xuyen, Than Thuy, 08.XII.2000, leg.

PARATYPES: 2 La, same locality; 2 La, Ha Giang Prov., Vi Xuyen, Tay Con Linh. 09.XII.2000, leg. V.V. Nguyen.</p> <p> <b>Diagnosis:</b> The head of <i>E. nguyenbaeorum</i> with its quadrangular shape and conspicuous pattern contrasts strikingly with that of <i>E</i>. <i>hieroglyphicus</i>, which has a rhomboid head with a central marking according to Braasch & Soldán (1984a: Fig. 22, p.112); marks of the pronotum occupy the anterior half in <i>E. hieroglyphicus</i>, whereas <i>E. nguyenbaeorum</i> has only an anteromedian brown mark. Contrary to <i>E. hieroglyphicus</i>, having a submedian row of oblique streaks along sterna, the new species is without any pattern. Microscopic structure of abdominal terga in <i>E. nguyenbaeorum</i> is quite different in showing hind margin fringes with relatively long setae alternating with short acute bristles (Nguyen & Bae 2004a: p. 24, Fig. 21), lacking in <i>E. hieroglyphicus,</i> which has 2 submedian tubercles covered with 2 minute, spiny bristles and scattered with short hairs at the posterior margin of each tergum (Braasch & Soldán 1984a: p. 112, Fig. 27). The gill set offers distinct differences in gill I being egg-shaped (Nguyen & Bae 2004a: p. 24, Fig. 22) in the new species, but pear-shaped in true <i>E. hieroglyphicus</i> (Braasch & Soldán 1984a: p.112, Fig. 28), and in gill VII being obovate, whereas that of <i>E. hieroglyphicus</i> is somewhat oblong and distally with an asymmetrically pointed tip; gill III is large and elliptical in both species.</p> <p> <b>Type deposition</b>: HOLOTYPE: <b>mature male La</b> (Figs. 19–24 see above), in Department of Invertebrate Zoology, Faculty of Biology, Hanoi University of Science, Vietnam; PARATYPES: 1 La at the same place; 2 La in College of Life Science & Biotechnology, Korea University, Korea.</p>Published as part of <i>Braasch, Dietrich & Boonsoong, Boonsatien, 2010, A contribution to the Heptageniidae (Insecta, Ephemeroptera) of Thailand and Malaysia, pp. 1-26 in Zootaxa 2610</i> on pages 19-20, DOI: <a href="http://zenodo.org/record/197793">10.5281/zenodo.197793</a&gt
