Abstract:

Intraproboscis sanghae Amin, Heckmann, Sist, Basso, 2021 (Acanthocephala: Gigantorhynchidae) was described from 4 females of 7 specimens obtained from a black-bellied pangolin, Phataginus tetradactyla Linn. (Manidae) in the Central African Republic. No males were available at the time. We, however, came upon two specimens of the same species, a male and a female, collected from a white-bellied pangolin, Phataginus tricuspis Rafinesque in central Africa which makes this finding a new host record for I. sanghae. The female specimen was whole and its measurements fell within the range of measurem

Abstract:

The use of non-invasive techniques to study a wide array of zoological specimens has been increasing considerably during the 21st century. Among these techniques, micro-computed X-ray tomography (μ-CT) is gaining much attention. This method may allow access to hardly visible and internal structures of valuable specimens (e.g. type specimens) through virtual dissections. We studied two type specimens of Ephemeroptera belonging to the family Heptageniidae using μ-CT; the male lectotype of Epeorella borneonia Ulmer, 1939 (pinned specimen) and the male holotype of Rhithrogeniella ornata Ulmer, 193

ABSTRACT Stenogeocoris Montandon, 1913 was described to include S. horvathi based in one specimen from Córdoba Province, Argentina. The type specimen is lost and there are no records or additional material since the Montandon's description; thus, the identity of this taxon has remained uncertain until now. In this contribution, we redescribe the genus Stenogeocoris and the species S. horvathi, based on male and female specimens, including characters from the male genitalia, and compare Stenogeocoris with the other Neotropical genera

The morphological description of P. drogon is expanded here, based on the male holotype and the newly collected female specimen.

Abstract:

Natural history specimens are widely used across ecology, evolutionary biology and conservation. Although biological sex may influence all of these areas, it is often overlooked in large-scale studies using museum specimens. If collections are biased towards one sex, studies may not be representative of the species. Here, we investigate sex ratios in over two million bird and mammal specimen records from five large international museums. We found a slight bias towards males in birds (40% females) and mammals (48% females), but this varied among orders. The proportion of female specimens has no

Abstract Haemaphysalis longicornis Neumann, the Asian longhorned tick (ALT), has quickly established widespread invasive populations in the United States since its first at-large detection in 2017. Until recently, no male ALT has been verifiably collected in the United States, despite examinations of tens of thousands of individual specimens, thus affirming that the US incursion was founded by ticks from a parthenogenetic source population of ALT.

Abstract:

Sakai (2015) erected a new callianassid ghost shrimp taxon Gilvossius chichijimaensis diagnosed on the basis of Komai & Tachikawa’s (2008) text and figures of a male specimen originally identified as Paratrypaea bouvieri (Nobili, 1904). A holotype was designated “CBM-ZC 7244, holotype male (cl 7.4 mm), Chichijima Island, Tokyo Prefecture”. This registration number appears to be a mistranscription from Komai & Tachikawa’s (2008) list of specimens which includes “Chichi-jima Island: … CBM-ZC 7422, 2 males (5.2 mm, 7.4 mm), 1 ovigerous female (cl 6.9 mm), Okumura River, rivermouth, tidal

Abstract:

A male and female specimen of Prorates ballmeri Nagatomi and Liu were collected while in copula. The specimens were dissected to find that the elongate distiphallus of the male had been inserted within the spermathecal ducts of the female. The association of the male and female genitalia for this species is figured and discussed in relation to associated taxa with similar genitalic features. The species was originally described from three male specimens, which did not allow for comprehensive study of the variation in many characters. The male is redescribed based on many newly collected specim

Abstract:

The labrid fish Cirrhilabrus sanguineus Cornic is redescribed on the basis of the neotype, two male specimens, and an additional female specimen recently collected from the northern coast of Mauritius. We provide new live and nuptial colouration descriptions, as well as the first documented female specimen for the species. we also include a molecular phylogenetic analysis of related species, with brief comments on phylogenetic interpretation of putative relationships amongst members of the genus Cirrhilabrus.

Abstract:

Two Lophocampa species previously known only by females are paired with morphologically highly different male specimens. This pairing was initiated after the discovery of a mosaic gynandromorph specimen and then confirmed using the mitochondrial COI gene (the so-called DNA barcode). Following the discovery of a labeling error by Rothschild during the original description of two species, two recombinations are proposed. Pairs for each species are illustrated and the male specimens are described for the first time.

The diploid number was found to be constant, i.e., 2n = 42 chromosomes, although two karyotypic forms were found: karyotype A, characterized by 22M + 20SM chromosomes, observed only in a male specimen, and karyotype B, characterized by 24M + 16SM + 2ST and 24M + 17SM + 1ST chromosomes in female and male specimens, respectively. This sex difference found in karyotype B is related to an XX/XY sex chromosome system. Another female specimen

Abstract:

The small upogebiid shrimp, Upogebia miyakei, was originally described from a female collected from Ishigaki-jima Island, Ryukyu Islands, southern Japan. However, no male specimen has been reported since the discovery of the holotype. During surveys at Iriomote-jima Island and its type locality, both females and males of U. miyakei were collected from the intertidal zone. Based on this material a full description of the male is given, and comparison with the female reveals the sexual dimorphic characteristics. The palm of the first pereiopod of male specimens is about 1.5 times wider than that

Abstract:

Ring-shaped specimen is commonly used in tests for determination of mechanical properties for arteries in hoop direction, especially for small mammals such as rats or mice. Although ring test is a lot more convenient than the tests concerning strip specimens, interpretation of the experimental data might be inconclusive – it is difficult distinguish whether it's still straightening up or the actual tension begins. The basic problem is to properly define initial length of specimen, which is essential for strain calculation. The purpose of this study was to evaluate various methods for strain ev

Seventy-six years later, the first male specimen of the genus Mopla was discovered in the Western Ghats, Kerala, India, in 2016. This paper describes the specimen, thought to be of Mopla guttata, and reconsiders its systematic placement.
