Basionym:— Cnemidostachys glandulosa Martius & Zuccarini (1824: 139); Martius (1824: 71). — Sebastiania corniculata var. obtusifolia forma glandulosa (Mart. & Zucc.) Müller (1866: 1168).— Sebastiania glandulosa (Mart. & Zucc.) Pax in Pax & Hoffmann (1912: 100).— Sebastiania glandulosa var. obtusifolia forma calvescens Pax in Pax & Hoffmann (1912: 101), nom. inval. Lectotype (designated here): BRAZIL. Minas Gerais: in campis, without date, C. F. P. von Martius s.n. (M-0164455!, isolectotypes M- 0164454!, M-0164456!). Cnemidostachys glandulosa had been overlooked by Esser (1998), and was later listed as synonym of M. corniculata (Vahl) Griseb. by Govaerts et al. (2000: 1186), which was certainly erroneous. It is a separate species, characterized by broadly elliptic to suborbicular, pubescent leaves with an obtuse to rounded (never cordate) base, an obtuse to subacute apex and several distinct marginal glands on the lower surface, which are situated in small lateral lobes that give the leaves a slightly dentate appearance (hence the appropriate epitheton). The species is very similar to M. hispida; the latter species shows, however, elliptic-lanceolate leaves with usually acute to acuminate apex, shoots and twigs are hollow or not in cross section, the fruits are regularly tricarpellate, with conspicuous appendages often pointing upwards, the pubescence is velutinose in addition to hispid and never uncinate hairs, the growth of the plants is erect and never caespitose. M. glandulosa differs from it, in addition the leaf shape, by the stems never hollow, the fruits quite often showing one or two aborted carpels with only vestigial to reduced appendages, the trichomes hispid and often uncinate, and the plants are often caespitose. Among the three type sheets in M, the only one with the original label of Martius is selected as lectotype (the others being duplicates with copied labels), which is also the only one with an annotation label of Müller Argoviensis attached to it. The leaves of the lectotype are slightly larger (30–35 × 13–15 mm) than those of the duplicates (15–25 × 8–12 mm).Published as part of Silva, Marcos José Da & Esser, Hans-Joachim, 2011, Two new taxa and two new combinations in Microstachys (Euphorbiaceae) from South America, pp. 18-26 in Phytotaxa 32 on pages 19-20, DOI: 10.11646/phytotaxa.32.1.2, http://zenodo.org/record/489476
Cryptophagus grahammontanus Esser 2018, nov.sp.
No full textCryptophagus grahammontanus nov.sp. T y p e m a t e r i a l: Holotype ♂: " Arizona: Graham Mts., May 18 1969, K. Stephan leg [FSCA]. Paratypes: 2♂♂, 1♀ with the same data as the holotype [FSCA, cES]; 1♀: " Arizona Graham Mts., 9200 ft., April 25 1971, K. Stephan leg [FSCA]." E t y m o l o g y: Named after the Graham Mountains in Arizona (USA) where the types were collected. D e s c r i p t i o n: Male, 1.8 mm, hind wings absent, humeral callus nearly absent, with small tooth. Reddish-brown with legs and antennae paler, eyes of normal size. Punctation fine and moderately dense on head and pronotum, less dense on elytra (basal third). Covered with yellowish and decumbent pubescence. Pronotum hardly wider as long. Anterior callosity short but prominent, forming a hook. Lateral tooth in the middle, lateral margin concave before the tooth and convex behind the tooth. Rim of the margin indistinct before and distinct behind the tooth. Elytra strongly elongated. Legs more stout, antennae slender without any features, segment IX and X slightly transverse. C o m m e n t: Typical species which is similar to C. stephani (fig. 7) and very similar to C. bussi ESSER, 2017 (fig. 6). C. stephani has a strongly elongated pronotum, C. bussi a less elongated pronotum which is more elongated as in grahammontanus with more convex posterior margin. Legs and antennae are in grahammontanus more slender than in bussi. Cryptophagus bussi was described from the Magdalena Mountains in New Mexico. So far known, the species seems to be restricted to this mountain range. It is obvious, that C. grahammontanus is also restricted to mountain range of the Graham Mountains.Published as part of Esser, Jens, 2018, New Cryptophagus H, 1792 (Coleoptera: Cryptophagidae) from Arizona (United States of America), pp. 1067-1071 in Linzer biologische Beiträge 50 (2) on page 1069, DOI: 10.5281/zenodo.377644

Sinop [ZMB, cES].</p> <p> Das Taxon <i>Dapsa nigripennis</i> REITTER, 1879 wurde von AUDISIO & DE BIASE (1996) mit <i>Dapsa limbata</i> MOTSCHULSKY, 1835 synonymisiert (Abb. 2, 4). Die Grundlage dafür waren ein als <i>limbata</i> MOTSCHULSKY gedeutetes Weibchen aus der nordwestlichen Türkei (Umg. Bolu) und ein weiteres Weibchen (der Typus von <i>D. nigripennis</i> REITTER) aus der Umgebung der heute Gjumri genannten armenischen Stadt (ehemals Alexanderhilf, Alexandroupolis oder Leninakan).</p> <p>Aufgrund einer ähnlich geringen Anzahl von Tieren kamen auch SEMENOV & NIKITSKY (2001) zu keinem anderen Schluss und behielten die Synonymie bei.</p> <p> Da das typische Material beider Arten weiterhin als verschollen gelten muss (<i>D. limbata</i> MOTSCHULSKY) oder nur noch aus einem einzelnen Weibchen besteht (<i>D. nigripennis</i> REITTER - REITTER (1879) nannte allerdings zwei Exemplare), ist auch die hier vorgenommene Revalidierung nicht gänzlich frei von Zweifeln. Doch der Zugriff auf Material (inkl. männlicher Tiere) aus der Nähe der beiden Typenfundorte lässt das Vorhandensein zweier Arten zweifelsfrei erkennen und eine Anwendung auf die beiden vorhandenen Namen erscheint als die naheliegende Lösung.</p> <p> Der Typenfundort von <i>D</i>. <i>limbata</i> wird von MOTSCHULSKY (1835) mit "sur les montagnes d'Akhalzik en Arménie " angegeben. Die Region liegt heute im Grenzgebiet von Georgien (Provinzen Adscharien und Samzche-Dschawachetien) und der Türkei (Provinzen Artvin, Ardahan und Ezurum). Aktuelles Material liegt aus der weiter westlich gelegenen türkischen Provinz Kastmonu und der weiter östlich gelegenen armenischen Provinz Kotajk vor.</p> <p> Von <i>D</i>. <i>nigripennis</i> REITTER liegt der Typenfundort in der Nähe des heutigen Gjumri in Armenien. Jüngeres Material wurde in der türkischen Provinz Sinop gesammelt.</p> <p> Demnach scheinen beide Arten von Armenien und Georgien entlang der türkischen Schwarzmeerküste nach Westen verbreitet zu sein. AUDISIO & DE BIASE (1996) geben noch die türkische Provinz Bolu an, von wo ihnen ein Weibchen vorlag. Es wäre aber empfehlenswert, männliche Exemplare (so vorhanden) aus dem Nordwesten der Türkei auf die Artgleichheit mit <i>D. limbata</i> MOTSCHULSKY oder <i>nigripennis</i> REITTER zu prüfen, da in anderen Fällen die kaukasischen Arten dort bereits durch verwandte Arten ersetzt werden (ESSER 2017, ESSER 2019).</p> <p>Im Grunde sind beide Arten gut unterscheidbar, v. a. die Männchen mittels Aedoeagus. Bei den Weibchen wie bei Männchen ohne Genitalpräparat bietet der Fühlerbau eine gute Unterscheidungsmöglichkeit (Tab. 1).</p>Published as part of <i>Esser, Jens, 2019, Anmerkungen zur Gattung Dapsa L, 1829 (Coleoptera, Endomychidae), pp. 907-914 in Linzer biologische Beiträge 51 (2)</i> on page 908, DOI: <a href="http://zenodo.org/record/3741910">10.5281/zenodo.3741910</a>

E t y m o l o g y: Named after Richard J. Buss, Albuquerque (USA), who collected the most of the type-specimens. D e s c r i p t i o n: Male, hind wings absent, 2,2 mm. Body elongate, elytra broadest in the middle, pronotum 1,4 times broader than long. Pubescence light and fine, only with procumbent hairs. Punctation of the pronotum relatively fine, distance between the punctures in the middle of the surface like the diameter. Punctation of the elytra (basal third) like that of the pronotum. Eyes small but convex, head above the eyes wide as the pronotum between the anterior angles. Antennae slender, 11-segmented with a 3- segmented club (fig. 4). Pronotum 1,4 times broader than long, anterior callosity thickened, with a prominent tooth. Tooth on the margin of the pronotum in the middle, sides behind the tooth convex, in front of it strong concave. Elytra elongate oval, widest in the middle, humeral callus absent. C o m m e n t: Quite characteristic wingless species. The shape of the pronotum resembles C. porrectus CASEY, 1900 (fig. 6) and C. varus WOODROFFE & COOMBS, 1961 (fig. 7), but both are fully winged. C. porrectus was found together with C. bussi in the same pitfall-traps. C. porrectus has a wide distribution throughout the USA. D i s t r i b u t i o n: As far as known restricted on the Magdalena Mountains in New Mexico (fig. 8, 9 and 10). A wider distribution in the mountains ranges of New Mexico is conceivable, also in the neighbouring states.Published as part of Esser, Jens, R, Nearctic, Usa & M, New, 2017, Two new species of Cryptophagus HERBST, 1792 (Coleoptera: Cryptophagidae) from New Mexico (United States of America), pp. 571-576 in Linzer biologische Beiträge 49 (1) on pages 574-575, DOI: 10.5281/zenodo.535733
