Notes of the trichobothrial patterns in damsel bugs (Insecta: Hemiptera: Nabidae).

A trichobothrium is a complex sensory organ, which usually consists of a long, slender mechanoreceptive seta (trich), which is situated in a cuplike depression in the cuticle (bothrium). Nabidae (Hemiptera: Heteroptera: Cimicomorpha), also called damsel bugs, are a relatively small family within which two subfamilies, Nabinae and Prostemmatinae, are distinguished. Trichobothria are present in the number of one to seven pairs located laterally on the scutellum of adult representatives of Prostemmatinae. This feature is commonly used to distinguish this subfamily from Nabinae. Trichobothria are also found on the abdominal tergites of Prostemmatinae nymphs. Similar sensilla have been observed in adult representatives of Nabinae, but their homology has not yet been confirmed. During morphological studies on Nabidae, conducted using scanning electron microscopy, we noticed sensilla resembling trichobothria on the heads of these insects. This discovery prompted us to examine the presence of these structures in damsel bugs more carefully. Imagines of fifteen species of both subfamilies were analysed using a scanning electron microscope. The results present data on the distribution and micromorphology of the trichobothria in damsel bugs. A pair of dorsal and ventral cephalic trichobothria were observed in all of the examined species of subfamily Nabinae. These sensilla were not found on the heads of Prostemmatinae. The results of studies on scutellar trichobothria confirmed the previously known data regarding their occurrence in Prostemmatinae. Moreover, our research showed the presence of these sensory structures in all of the examined Nabinae species: one pair of trichobothria in Arachnocorini, Carthasini, Gorpini and Nabini, and two pairs in Stenonabini. The presence of abdominal trichobothria was shown in Nabini and Stenonabini. In the remaining studied tribes of Nabinae and in the subfamily Prostemmatinae, the presence of structures that could undoubtedly be considered abdominal trichobothria was not found.

Revisiting the Taxonomy of Cylapocoris Carvalho, 1954 (Hemiptera: Miridae: Cylapinae) with Descriptions of Five New Species and Morphology-Based Phylogenetic Analysis of the Genus.

This paper provides descriptions of five new species of the Neotropical genus Cylapocoris Carvalho, 1954 (C. bimaculatus n. sp., C. brooksi n. sp., C. carvalhoi n. sp., C. scutellatus n. sp., and C. simplexoides n. sp.). Cylapocoris and Cylapocoroides Carvalho, 1989 are redescribed and rediagnosed. Illustrations of male genitalia, scanning electron micrographs of selected structures of certain taxa, and an identification key to species are provided. Female genitalia are described and illustrated for the first time for Cylapocoris in nine out of 19 known species. A cladistic analysis of the genus, based on 62 morphological characters, is presented as a contribution to the understanding of relationships within Cylapocoris and its relationships with other groups of Cylapinae. The analysis comprises 16 ingroup species and 15 outgroup taxa. Both equal and implied weighting parsimony analyses were used in the phylogenetic reconstruction. We confirm the monophyly of Cylapocoris and its sister-group relationship with Cylapocoroides. Additionally, we identify subgroupings within Cylapocoris. Intertribal relationships within Cylapinae are briefly discussed.

Closer view of antennal sensory organs of two Leptoglossus species (Insecta, Hemiptera, Coreidae).

Detailed description of antennal sensory organs of Leptoglossus occidentalis Heidemann, 1910 (Insecta: Hemiptera: Heteroptera: Coreidae) and a comparison with L. zonatus (Dallas, 1852) are presented. A novel approach that combines the advantages of field emission scanning electron microscopy (FE-SEM) and atomic force microscope (AFM) was used to detail micromorphological structures. A simplified classification system for sensilla that eliminates the subjective aspects of morphology, such as their shape, is proposed. Fourteen sensory organs have been classified into three main groups: (a) aporous sensilla with a flexible socket, (b) porous sensilla with a flexible socket and (c) porous sensilla with an inflexible socket. A large variety of sensory organs (nine types) with olfactory functions are described. The antennal sensory organs have been recognized as one of the factors responsible for the evolutionary success of Leptoglossus spp. and their status as important pests and invasive species.

Labial Sensory Organs of Two Leptoglossus Species (Hemiptera: Coreidae): Their Morphology and Supposed Function.

A detailed description of the labial sensory organs of Leptoglossus occidentalis Heidemann, 1910 and L. zonatus (Dallas, 1852) (Hemiptera: Heteroptera: Coreidae) is presented. The detailed morphology, location, and distribution of different sensilla types on mouthparts were investigated and shown in micrographs taken with a scanning electron microscope. Nine types of aporous sensilla, and three uniporous sensilla were found. The possible functions of these sensilla as well as similarities and differences between the mouthparts of Leptoglossus and those of other terrestrial Heteroptera are discussed. The tip of the labium constitutes a functional "touch and taste area", combining the chemosensitivity of uniporous sensilla P1-P3 and the mechanoreceptivity of A8 and A9 hair-like sensilla. A set of two cone-like chemosensilla types (9 + 2) was found on each lateral lobe of the labial tip. Literature analysis showed that such a set of cone-like sensory organs on the labial tip may be common in terrestrial Heteroptera. This observation confirms that the number and arrangement of sensilla is conservative and can be important in diagnosing taxa at various levels and in phylogenetic studies based on morphology.

From Asia to Europe? Where Could the Geographical Place of Origin of Polymerus (Pachycentrum) carpathicus (Horváth, 1882) (Hemiptera: Miridae) Be?

This paper presents the first record of a rare species of Miridae, Polymerus (Pachycentrum) carpathicus (Horváth, 1882), in Poland. A broad analysis of its occurrence was conducted, which was based on modelling its potential ecological niche using past and future models, which enabled new and valuable information about the potentially suitable habitats and its possible range of distribution as well as its climatic preferences to be identified. The results of the research indicate that P. (P.) carpathicus prefers habitats in highlands and mountains. This species probably came to Europe from Asia via a postglacial migration and the disjunctive range that characterises P. (P.) carpathicus may be due to a lack of data. Additionally, the key to identifying the Polish species from the subgenera Pachycentrum and Polymerus and maps of their distribution in Poland are also presented.
