RESUMEN

Among the currently recognized 71 extant genera of Glandulariini, Afroeudesis Franz shows an unusual distribution, with strikingly similar species known from South America, west and east Africa, and the sub-Himalayan region of Asia. Morphological studies revealed that several species placed in other genera share with Afroeudesis several unique characters, among others a symmetrical pattern of numerous setae on the frons and vertex, not known in any other Glandulariini. This 'Afroeudesis group' is here recognized to be composed of the Neotropical genera Meridaphes Jaloszynski, Stenichnoconnus Franz and Pseudoraphes Franz, the broadly distributed Afroeudesis, and the Neotropical Bicarinulodes gen. n. The last is proposed for a species previously misplaced in Microscydmus Saulcy Croissandeau, resulting in Bicarinulodes meridensis (Franz) comb. n. Bicarinulodes is most similar to Afroeudesis, but (among other differences) it lacks the apomorphy that is unique for the latter genus, the raised subtriangular 'platform' on the frons and vertex. Stenichnoconnus minor (Franz), comb. n is proposed for Euconnus minor (Franz), originally published as Venezolanoconnus minor Franz. Stenichnoconnus and Pseudoraphes are redefined and redescribed.

RESUMEN

Morphological structures of several glandulariine genera known to occur only in North America have never been properly described and illustrated. In consequence, status and diagnoses of some potentially key taxa to understand the evolution of the Northern Hemisphere Scydmaeninae remain unclear. Comparative morphological study of Catalinus and Parascydmus is intended to reduce this gap. Examination of type species revealed that both genera belong to glandulariine taxa characterized by the submentum demarcated laterally by sutures. The status as separate genus for Catalinus and Parascydmus is maintained. The most interesting discovery is that the Nearctic Parascydmus resembles most the endemic Japanese Rutaraphes; among other characters, these taxa share a uniquely modified frons and the aedeagus lacking parameres.

RESUMEN

Among previously known Palaearctic species of Chevrolatia Jacquelin du Val, adults of only two have unmodified male protrochanters. Another species showing this character is described, Chevrolatia iberica sp. n., based on a specimen collected in the Spanish province of Alicante. It differs from its two sympatric congeners, C. hispanica Franz and C. sylvanica Hernando Castro, in a combination of conspicuously short apical projections of the aedeagus, a strongly curved median lobe, a short capsular component of the endophallus, and the parameral setae of subequal length and sparsely, evenly distributed.

RESUMEN

Two species of Euthiconus Reitter were previously known to occur in the Palaearctic region, distributed in Europe (E. conicicollis (Fairmaire Laboulbène)) and in the Russian Far East (E. lustrificus Kurbatov). A description of the first Japanese species, Euthiconus nopporoensis sp. n., is given, based on specimens collected on Hokkaido. The new species shares with E. lustrificus unmodified male protrochanters and a similar shape of the pronotum; it differs in a bottle-shaped aedeagus, sparser setae on the pronotum, and a shorter antennomere III. Key morphological structures of all Palaearctic species of Euthiconus are illustrated, to facilitate identifications.

RESUMEN

Borneoconnus, a subgenus of Euconnus endemic to Borneo, is revised. Euconnus laticlava Franz (type species of subgenus), E. eremita Franz and E. sabahanus Franz are redescribed. Morphological structures of E. laticlava are illustrated and described in detail. It is concluded that Borneoconnus is most similar to Euconnus s. str., Napochus Thomson and Psomophus Casey; differences in morphological structures are discussed. Borneoconnus is maintained as a separate subgenus, pending further study, as this name seems to be a candidate to place as a junior synonym of Napochus in a future reclassification of Euconnus subgenera. The variability in the pronotal form found within otherwise morphologically uniform Borneoconnus species supports a weak taxonomic value of this character to use in subgeneric diagnoses. This observation may result in merging Euconnus s. str. and Napochus Thomson, and possibly also Borneoconnus, in one subgenus. However, the yet unrevised subgenera of Euconnus must be studied before such an action is taken.

RESUMEN

Only two genera of the cosmopolitan tribe Cephenniini are known to occur in the People's Republic of China: Cephennodes Reitter and Cephennomicrus Reitter. The former is species-rich and abundant, especially in subtropical and sub-Himalayan areas, and so far nearly 80 species have been recorded in China. Cephennomicrus is rare, and only two species have been found in this vast country, in the south-eastern province of Fujian. Two new species are reported to occur in Yunnan: Cephennomicrus yunnanicus sp. n. and C. andreasi sp. n.

RESUMEN

All species of the cephenniine genus Cephennomicrus known to occur in the Seychelles were described by Scott (as Neseuthia) nearly a century ago. The descriptions were based on external characters, which does not allow for species identification. All the species are redescribed here: C. cordithorax, C. cornutus, C. minor, C. perexiguus, C. politus and C. typicus. Cephennomicrus crenatus is transferred to another genus, resulting in Pomphopsilla crenata comb. n. Lectotypes are designated for Neseuthia minor, N. perexigua and N. crenata. A new species group within Cephennomicrus is proposed to accommodate all species treated here, which share, among other characters, a long flagellum with a broad proximal portion, very short setae on the pronotum and elytra, five pronotal antebasal pits, a transverse groove connecting three of them, and unique modifications of the head in males.

RESUMEN

The genus Microscydmus Saulcy Croissandeau is recorded for the first time from the Japanese Archipelago. Eight species are described: Microscydmus okinawanus sp. n., M. oharaensis sp. n., M. nishimeanus sp. n., M. kochiensis sp. n., M. elytratus sp. n., M. tibialis sp. n., M. yusuharanus sp. n., and M. omogonus sp. n. All new species are placed in the nominotypical subgenus, and Japan becomes a country that houses the greatest recorded species richness of Microscydmus (s. str.). The new species are distributed on Shikoku and in the Ryukyus. A novel character was found, previously unknown in Microscydmus: a pair of long lateral setae on the posterior margin of vertex, clearly visible in some of the newly described species. These setae are not thicker than surrounding ones, but stand out because of their remarkable length. A re-examination of SEM images obtained during previous studies confirmed the presence of these setae also in M. nanus, the European type species of the genus, in which, however, these setae are obscured by surrounding vestiture. Among Glandulariini, such a pair of setae has been known only in the extinct Upper Cretaceous Scydmobisetia Jaloszynski Yamamoto.

RESUMEN

The 'Cephennomicrus group' of Cephenniini includes nine genera distributed mostly in SE Asia (but with some species known also from other continents, except for the Americas). Four new Oriental species are described: Cephennococcus penangensis sp. n. (W Malaysia), Cephennomicrus matangensis sp. n. (E Malaysia), Cephennomicrus selangorensis sp. n. (E Malaysia), and Trurlia nova sp. n. (E Malaysia). Cephennomicrus selangorensis is unique in having the pronotum in both sexes with broad lateral impressions demarcated from the disc by a sharp ridge, a modification slightly similar to that of only one (Australian) congener.

RESUMEN

Five currently known Japanese species of the eutheiine genus Paraneseuthia occur on Honshu, Shikoku, Kyushu, and Ishigaki-jima of the Ryukyu Archipelago. The southernmost Japanese species was separated from its geographically (and very likely phylogenetically) closest relatives that live on Kyushu by over a thousand kilometers of the Pacific Ocean. Paraneseuthia zanetae sp. n., found on Okinawa-jima, the largest Ryukyuan island, is described, filling this wide distributional gap. The new species is yet another member of the informal P. paradoxa group, which comprises all Japanese members of this genus that share similar male protibial modifications and a complicated structure of the aedeagus; also two Russian Far Eastern species show close morphological affinities to those inhabiting the Japanese Archipelago.

RESUMEN

Most species of Euconnus (Cladoconnus) inhabit West Palaearctic, and only three are known from East Asia. The latter form a morphologically uniform group that comprises E. ussuriensis (Primorsky Krai), E. matsuae (Central Honshu) and E. nakahamai (Shikoku). These species cannot be reliably distinguished by external features; they differ mainly in the shape of the endophallic sclerites. Diagnostic characters of these species are summarized, and a new member of the E. ussuriensis species group is described, Euconnus (Cladoconnus) rudimentalis n. sp. (South Korea). Members of this group are restricted to the areas surrounding the Sea of Japan; the known distribution suggests that similar species can be expected to occur also in the northern part of the Japanese Archipelago and in North Korea.

RESUMEN

In 2011 phylogenetic relationships of 'Cephennomicrus group' of Cephenniini were studied and several new genera were described. Two taxa, each represented by a single female and referred to as genus X1 (Sulawesi) and X2 (Philippines), were included in that study. Recently, a new sample of scydmaenines from Luzon has become available to my study, including a series of male and female specimens of the genus X2. Clavomicrus orousseti gen. sp. n. is here described based on this material. SEM data are added to morphological structures previously illustrated on the basis of transparent slide preparations. Clavomicrus is the second genus of Cephenniini with the antennomere X and XI fused together into a histerid-like, abruptly delimited, oval club.

RESUMEN

Until now, Penicillidmus was represented by two Australian and one Papuan species, distributed in Cape York, northern Queensland, and Lavongai Island, Papua New Guinea. Three new species are described, all known to occur in Luzon, the Philippines: Penicillidmus maquilingensis sp. n., P. lagunensis sp. n. and P. luzonicus sp. n. The discovery of Penicillidmus in the Oriental region suggests a broader distribution of this genus in Southeast Asia.

RESUMEN

The genus Stenichnodes is known to occur in Africa and SE Asia, and is divided into two subgenera. The sole African species belongs to Stenichnodes s. str. and is known from a single male specimen found in Chad. A specimen collected in Kenya that has spent nearly 30 years in a museum collection misidentified as a female of Parastenichnaphes cf. sumatrensis (sic!) is here recognized as a male of Stenichnodes s. str. and described as S. error sp. n.

RESUMEN

The genus Marcepania is a sole member of the tribe Marcepaniini, known to occur in SE Asia. The five hitherto described species inhabit the Malay Peninsula and Borneo. The first species discovered in the Philippines, Marcepania princesa sp. n. is described here, based on a male specimen found on the island of Palawan. It is most similar to its geographically closest relative, M. elongata of northern Borneo.

RESUMEN

Three species of the extinct Eocene genus Baltostigus (Mastigitae: Baltostigini) were known in Baltic amber from Poland, Lithuania and Russia. In Rovno amber, although it was relatively well-studied, only one Mastigitae genus and species was recorded, belonging to Leptochromini. We report the occurrence of Baltostigus in the area of the present day Ukraine during the Eocene, on the basis of three inclusions in Rovno amber. One specimen belongs to a newly described species, Baltostigus substriatus sp. n.; two specimens are putatively identified as Baltostigus cf. horribilis, and may represent females of this species. However, further study based on more specimens is necessary to clarify the identity of these specimens.

RESUMEN

Until now, two species of Clidicus were known to occur in the Philippines, both inhabiting Mindanao. The scarcity of published records (merely six known Philippine specimens of this genus) suggested that Clidicus was rare in this country. We here falsify this view, by describing five new species and providing new records of the previously known species, based on a material of over 80 specimens collected on Mindanao and Luzon. Clidicus forceps Cheng, Yin Jaloszynski, sp. n., C. interfector Jaloszynski, Cheng Yin sp. n., C. kalis Jaloszynski, Cheng Yin sp. n., C. occisor Jaloszynski sp. n., and C. shavrini Jaloszynski sp. n., are described. Clidicus crocodylus Jaloszynski, previously known to occur on Mindanao, is for the first time recorded in Luzon.

RESUMEN

Nearctic Microscydmus Saulcy & Croissandeau includes species placed in Microscydmus s. str. and subgenera Delius Casey and Neladius Casey. The two latter taxa were originally described as genera, and all Nearctic species of Microscydmus s. str. were placed in a genus Opresus Casey, currently treated as a junior synonym. Detailed examination of the type species of Opresus, Delius and Neladius leads to the following conclusions and changes: Opresus is removed from synonymy with Microscydmus s. str. and placed as a subgenus of Microscydmus; Delius and Neladius are restored as genera. The two latter taxa belong to a group of glandulariine genera characterized by the submentum with lateral sutures, whereas Microscydmus does not have such structures. The type species of the studied genera and subgenera are redescribed: Microscydmus (Opresus) misellus (LeConte), comb. rest., Delius robustulus Casey, comb. rest., and Neladius tenuis Casey, comb. rest. Lectotypes are designated for Scydmaenus misellus LeConte, Delius robustulus Casey and Neladius tenuis Casey.

RESUMEN

Based on examination of type species, Alloconophron, previously a subgenus of Euconnus, is placed as a subgenus of Anhoraeomorphus, resulting in Anhoraeomorphus (Alloconophron) grucheti (Franz) comb. n. and Anhoraeomorphus (Alloconophron) impressifrons (Franz) comb. n. All species of Anhoraeomorphus are known to occur in Madagascar. Noctophus stat. rest., a North American taxon originally described as a genus and later placed as a subgenus of Euconnus, is restituted as genus and redefined. Noctophus is morphologically surprisingly similar to Anhoraeomorphus, it also shares many structures with the Australo-Pacific Sciacharis. As Noctophus is known from one species represented by a single female holotype only, and the maxillary palps of this specimen are missing, the proposed placement of Noctophus is tentative and requires further study based on complete male specimens.
