A review of the Malagasy species of the genus Trigonochilus Brenske (Coleoptera: Scarabaeidae: Rutelinae: Adoretini) with description of a new species

Africa and Madagascar have a large and diverse fauna of the chafers of the ruteline beetle tribe Adoretini (Ohaus 1912, 1918). Many nominal taxa from Madagascar are still poorly known and many new ones were described recently (Akhmetova & Montreuil 2010; Montreuil 2010, 2013; Montreuil & Frolov 2014; Frolov & Montreuil 2018). One of the poorly known Adoretini taxa is the genus Trigonochilus Brenske, 1896. Trigonochilus was proposed to accommodate the East-African species T. coriaceus Brenske, 1896, based on the enlarged and curved metatibiae and a short, spur-like process of the labrum (Brenske 1896). Arrow (1901) noted that the enlarged metatibiae of this species (described from a single male) is a secondary sexual character and added another species to this genus, T. politus Arrow, 1901, from Angola. These species were revised by Krikken (1979). Fairmaire (1903) described Adoretus oedipus from Madagascar (without any precise locality) and noted its enlarged metatibia and the shape of the labrum similar to that in Trigonostonum Burmeister, 1844. Fairmaire was apparently unaware of the Brenske’s and Arrow’s works as he did not discuss the possible affinities of A. oedipus with Trigonochilus species. Ohaus (1912) moved A. oedipus to Trigonochilus after examination of the type series but he did not discuss the characters of the species in detail as well as its distribution on the island. Therefore, the genus Trigonochilus Brenske comprised three species described so far, two from Africa and one from Madagascar.

Lithobius (Monotarsobius) meifengensis, a new species of centipede from high altitude forest in central Taiwan (Chilopoda, Lithobiomorpha, Lithobiidae)

Lithobius (Monotarsobius) meifengensissp. n.occurring at Mei-Feng Farm, Highland Experimental Farm of National Taiwan University, Nantou, Taiwan, is characterised by a male secondary sexual character on leg 15, a very large ventral swelling occupying almost 50% of the ventral surface of the femur; the gently curved apical region bearing approximately 20 short setae and numerous very small pores of flexo-canal epidermal glands. This male secondary sexual character is described for the first time in the genusLithobius.

Turner’s Syndrome in Adulthood and Cytogenetics

Aims: Turner’s syndrome is a chronic disease of chromosomal aberration. The purpose of the study was to find out the accurate identification of cell line, which is critical for cytogenetic studies, genetic counseling, phenotypic studies carried out with few reconstructive procedures to plan future sexual and reproductive life. Methods: This study design was a prospective hospital based clinical study. In this study, ninety six patients were studied with secondary sex characters with relevant ultrasonogram findings and hormonal assay who underwent karyotyping in Bangabandhu Sheikh Mujib Medical University, Dhaka for a study period of ten years from October 1997 to October 2007. Results: Among 96 patients, 62.5 % of the patients were from 15-18 years. Four girls who were less than 15 years came with Turner’s and testicular stigmata. Twenty women aged more than 26 years presented with coital problems. Around 72.9% had no secondary sexual character, 20.83% had normal female type of secondary sex character, and 6.25% had virilizing type of secondary sexual character. Karyotyping of the cases revealed 72.9% (n = 70) had 45XO pattern, which belong to the Turner's stigmata and correlated well with the hormone profile. Whereas, 20.83% (n = 20) had 46XX pattern and 6.25% (n = 6) had 46XY pattern with testicular feminization syndrome with inguinal testis. Conclusions: About 60% of cases were in the 15-18 years age group. Most of the patients presented with no secondary sexual characteristics. 45XO chromosomal pattern was the most common presenting in 72.9% cases. DOI: http://dx.doi.org/10.3126/njog.v9i2.11744

The cumacean Genus Eudorella (Crustacea: Peracarida) from Japanese Waters, Northwest Pacific, and E. suluensis sp. nov. from the Sulu Sea, Indo-West Pacific

Cumacean crustaceans in the genus Eudorella (Leuconidae) from Japanese waters, in the Northwest Pacific, were examinedand the following 15 species were recognized: E. acuticaudata sp. nov.; E. æquiremis Hansen, 1920; E. bathyalis Vassilenko &Tzareva, 2004; E. bathyhwanghaensis sp. nov.; E. breviflagella sp. nov.; E. dentata Lomakina, 1955; E. emarginata (Kroer,1846); E. fusafusa sp. nov.; E. haradai sp. nov.; E. hwanghaensis Hong & Park, 1999; E. ohtai sp. nov.; E. orientalis sp. nov.;E. parahirsuta sp. nov.; E. ryukyuensis Akiyama & Gamô, 2005; and E. setoensis Akiyama & Gamô, 2006. In addition,Eudorella suluensis sp. nov., was collected from the Sulu Sea, Philippines, Indo-West Pacific, 688–693 m. These speciesinclude 2 groups on the basis of shared morphological characters. Eudorella bathyalis, E. breviflagella sp. nov., E. fusafusa, E.orientalis, and E. setoensis are characterized by a row of simple setae on each side of the carapace, with both E. breviflagellaand E, setoensis also characterized by a short flagellum on antenna 2 in adult males. The other group consists of Eudorellahwanghaensis, E. bathyhwanghaensis, and E. ryukyuensis, from southern Japan, and E. suluensis; with E. hwanghaensis and E. bathyhwanghaensis also characterized by a peculiar secondary sexual character on the tip of the 3rd pereopod in adult males.
