1. Comparative morphology and evolution of the cranial musculature in bees (Hymenoptera: Apoidea)

Author:

Arthropod structure & development 2021 v.65 pp. 101112
ISSN:

Subject:
Apoidea; arthropods; muscles; proboscis; skeleton; synapomorphy; terminology
Abstract:
... Comparative morphological studies in bees are mostly restricted to the skeleton, and the musculature of bees has not been explored much from this perspective. Here we investigate the head extrinsic musculature under an evolutionary perspective. The musculature of 34 bee species belonging to six major lineages and 26 tribes plus two apoid wasps is described, illustrated, and compared. A standardize ...

Abstract:
... The male reproductive system and spermatozoa of spiders are known for their high structural diversity. Spider spermatozoa are flagellate and males transfer them to females in a coiled and encapsulated state using their modified pedipalps. Here, we provide a detailed overview of the present state of knowledge of the primary male reproductive system, sperm morphology and the structural diversity of ...

Abstract:
... External and internal head structures of adult Coniopteryx pygmaea Enderlein, 1906, one of the smallest known lacewings, are described in detail for the first time. Possible effects of miniaturization and two hypotheses on the phylogenetic position of Coniopterygidae are evaluated and compared with data from literature. Several convergent modifications in C. pygmaea and other miniaturized insect s ...

4. Morphological study of the ovary in Hanseniella caldaria (Myriapoda; Symphyla): The position of oocyte-growth and evolution of ovarian structure in Arthropoda

Subject:
Chilopoda; Diplopoda; Pauropoda; Symphyla; arthropods; basement membrane; hemocoel; oocytes; synapomorphy
Abstract:
... In Arthropoda, the ovary is classified into Chelicerata-type and Mandibulata-type, based on the oocyte-growth position within the ovary. By contrast, oocytes of Diplopoda and Chilopoda grow within the hemocoelic space. However, as the position of oocyte-growth in Symphyla and Pauropoda has not been confirmed, whether the hemocoelic nature of oocyte-growth is common among myriapods remains ambiguou ...

5. Morphology of sting apparatus of Chrysidoidea (Hymenoptera, Aculeata)

Hymenoptera; area; arthropods; females; hosts; muscles; ovipositor; sting apparatus; synapomorphy
Abstract:
... The main synapomorphy for Aculeata is the sting apparatus, which allows the female to envenom potential prey or hosts. The sting is the modified ovipositor which is not used for laying eggs anymore. Here, we explore the morphology of the sting apparatus within the families of Chrysidoidea. 27 skeletal structures were recognized, including three (dp1vf, dorsal projection of first valvifer; ppa, pro ...

6. On the morphology and evolution of cicadomorphan tymbal organs

Subject:
Cicadidae; Fulgoroidea; arthropods; innervation; musculoskeletal system; synapomorphy; taxon descriptions; terminology
Abstract:
... Cicadas and many of their relatives (Hemiptera: Cicadomorpha) generate vibroacoustic signals using tymbal organs located on their first two abdominal segments. Although tymbals are well-studied in Cicadidae, their systematic distribution in other Cicadomorpha and their possible homologies to the vibroacoustic mechanisms of other Hemiptera have been debated for more than a century. In the present s ...

Abstract:
... The tarsal setae in 97 species of Leiodidae and eight outgroups were examined using SEM imaging and dissections. Modified adhesive setae present in males are referred to as “male tenent setae” (MTS). In most cases, dilated tarsomeres were associated with MTS, which were always present on the protarsi and sometimes the mesotarsi. MTS are reported for the first time on the mesotarsi of Leptodirini a ...

Abstract:
... Megasecoptera is an extinct group of insects with specialized rostrum-like mouthparts, which is a synapomorphy shared with all members of the Late Paleozoic Palaeodictyopterida, and markedly slender wings that are unable to flex backwards. Here we describe the close up morphology of Protohymenidae and Scytohymenidae and uncover new aspects of the endoskeleton (tentorium) of the head, structure of ...

Abstract:
... The egg structure of Zorotypus magnicaudelli, Zorotypus hubbardi and Zorotypus impolitus was examined and described in detail. Major characteristics of zorapteran eggs previously reported were confirmed in these species, with the partial exception of Z. impolitus: 1) a pair of micropyles at the equator of the egg's ventral side, 2) a honeycomb pattern on the egg surface, 3) a two-layered chorion, ...

Abstract:
... Termites have developed many exocrine glands, generally dedicated to defence or communication. Although a few of these glands occur in all termite species, or represent synapomorphies of larger clades, others are morphological innovations of a single species, or a few related species. Here, we describe the nasus gland, a new gland occurring at the base of the nasus of Angularitermes soldiers. The ...
