Abstract Peyrierocoris seyrigi (Villiers, 1970) is redescribed and its taxonomic position is revised to accommodate Vesbius seyrigi Villiers, 1970, erroneously described under the generic name Vesbius Stål, 1865. Redescription and drawings of the dorsal habitus and characters of the male and female genitalia, as well as a drawing of the ovarian egg of P. seyrigi (Villiers, 1970), are given. Two new species, P. gorczycai sp. nov. and P. herczeki sp. nov., are described and illustrated with 21 figures. Key words: Insecta, Hemiptera, Heteroptera, Reduviidae, Harpactorinae, Peyrierocoris, new synonym, new combination, new species, Madagascar
Introduction The subfamily Harpactorinae Amyot & Serville, 1843, with almost 300 genera and over 2000 species, is the largest subfamily in the family of assassin bugs (Reduviidae) (Maldonado Capriles, 1990). However, the representatives of this subfamily distributed in Madagascar have never been fully studied. There are only 23 genera of Harpactorinae recorded in Madagascar (Maldonado Capriles, 1990; Chłond & Junkiert, 2010; Chłond & Baňař, 2013) so far, and the newly described genus Peyrierocoris Chłond & Junkiert, 2010 belongs to a group of 11 genera distributed exclusively on the island. Vesbius Stål, 1865 is a small genus with 16 species described so far. Almost all of the known species (except one) are distributed in South East Asia, and only Vesbius seyrigi described by Villiers in 1970 has been recorded from Madagascar. An examination of type specimens as well as numerous specimens deposited in European collections clearly shows that this species does not belong to Vesbius but to the Peyrierocoris Chłond & Junkiert, 2010 and the subgenus Sicardicoris Chłond & Guilbert, 2012; consequently, a new combination is proposed to accommodate Vesbius seyrigi Villiers, 1970. Moreover, examination of unidentified materials from Madagascar deposited in the collection of the Muséum national d’Histoire naturelle, Paris, France, Národní muzeum, Praha, Czech Republic, and Koninklijk Museum voor Midden-Afrika, Tervuren, Belgium, revealed also specimens which belonged to two new species described in the present paper.
Material and methods The type specimens are preserved in the collection of the Muséum national d’Histoire naturelle, Paris, France (MNHN). External structures of dry-mounted specimens were examined using a stereoscopic microscopes Olympus SZX9 and Leica MZ16. All drawings were made using a camera lucida. Dissected genitalia were boiled in 10% KOH for 5 minutes to remove soft tissue, rinsed in distilled water, and dissected under a stereoscopic

microscope Olympus SZX9. Genitalia are stored in PVC microvials with glycerol, and attached on the pin with the dissected specimen. Measurements were made with an ocular micrometer under a stereoscopic microscope (Olympus SZX9) and are given in millimeters. Quoting the labels of specimens: (/) is used to divide data on different rows on the label, (;) is used to divide data on different labels, ([]) is used for author’s comments.

Taxonomy Genus: Peyrierocoris Chłond&Junkiert, 2010 Type species: Peyrierocoris (Peyrierocoris) mirabilis Chłond&Junkiert, 2010:34 (by original designation).
Diagnosis. Body medium-sized, slender, and shiny (Fig. 1). Head wide, with short and wide postocular region, distinctly downward clypeus, relatively large eyes and short antennifers (with apices directed frontally). Pronotum gradually expanded, apical lobe with distinct longitudinal suture. Hemelytra with straight margins on apical part of corium. Abdomen slender (males) or quadrangular (females). Posterior pronotal lobe rounded in posterior margin (Figs 21–23)), scutellum elevated in lateral view; median process of pygophore long with divided apex (Figs 6–8). Vesbius Stål, 1865 is similar to Peyrierocoris Chłond & Junkiert, 2010 only with respect to general body shape. It can be easily distinguished from Peyrierocoris by its short globular head (very short anteocular part of the head in dorsal view (Figs 30,31 )), with large eyes, smaller and more convex pronotum (Fig. 33), and a presence of coriaceus part of the hemelytra on membrane (in the basal part of apical internal and external cells) (Fig. 32).

Distribution. North Madagascar: Ampanefena, Nosy-Be—Lokobe Strict Reserve. Etymology. It is a pleasure to dedicate the name of this species to Jacek Gorczyca, the world specialist on Cylapinae and the supervisor of my PhD thesis. Comments. One female was collected on Nosy-Be Island as well as a second female deposited in the collection of Koninklijk Museum voor Midden-Afrika, Tervuren, Belgium (collected probably on the same island); these females have much clearer (yellowish) pronotum, clavus, and apical part of corium; moreover, the pale parts of the legs are red.
Discussion During the study of material from Madagascar deposited in the Muséum national d’Histoire naturelle, Paris, among unidentified material from Madagascar, a type specimens of V. seyrigii Vill. were checked. Examination of this material and comparison with the type specimens of other species of Vesbius deposited in the collection, confirmed that these specimens definitely does not belong to mentioned genus. Based on zoogeographical considerations— distributional data from the labels as well as information on the distribution of the genus Vesbius which has been reported in the catalog of Maldonao Capriles (1990) it was confirmed that the area of distribution of this genus is in South East Asia. Examination of all morphological characters clearly shows that this species does not belong to Vesbius but to Peyrierocoris Chłond & Junkiert, 2010. Besides the obvious differences like the distinctly more robust body and relatively small eyes placed in the middle part of the head in lateral view (Fig. 47), representatives of the genus Vesbius have very slender body and large eyes (relative to the size of the head) placed very near the anterior part of the head (Figs 46,47). Peyrierocoris differs from Vesbius by its distinctly different shape of the head (Figs 40–45). The anteocular part of the head in Vesbius is very short and distinctly rounded; the apical part of the antennifers reach or only slightly surpass the anterior margin of the eyes in dorsally (basal part of antennifers of Peyrierocoris are placed on anteocular part of the head, distinctly behind the anterior margin of the eyes in dorsal view (Fig. 46)). Apically on the femurs of Vesbius are three visible globular enlargements, which are absent in Peyrierocoris. One of the most important and most visible characters is the presence of coriaceus part of hemelytra on membrane (in the basal part of the apical internal and external cells of Vesbius) (Fig. 48); this character is absent in Peyrierocoris (Fig. 50). After examination of all morphological characters of both genera, it can be conclude that they seem not to be closely related. Examination of the morphological characters of the pronotum and scutellum between species described by Villiers (1970) and three species described by Chłond & Junkiert (2010) and Chłond & Guilbert (2012) (Figs 37– 39), as well as the shape and length of the median process of the pygophore (distinctly elongated (Figs 6–8)), confirmed that this species belongs to the subgenus Sicardicoris. With two subgenera Peyrierocoris Chłond & Junkiert, 2010, Sicardicoris Chłond & Guilbert, 2012, and only six known species: P (P.) guilberti Chłond & Junkiert, 2010, P.(P.) mirabilis Chłond & Junkiert, 2010, P.(S.) gorczycai sp. nov., P.(S.) herczeki sp. nov. P.(S.) niger Chłond & Guilbert, 2012 and P.(S.) seyrigi (Villiers, 1970)), is one of the smallest genus belonging to the subfamily Harpactorinae.

Abstract Peyrierocoris seyrigi (Villiers, 1970) is redescribed and its taxonomic position is revised to accommodate Vesbius seyrigi Villiers, 1970, erroneously described under the generic name Vesbius Stål, 1865. Redescription and drawings of the dorsal habitus and characters of the male and female genitalia, as well as a drawing of the ovarian egg of P. seyrigi (Villiers, 1970), are given. Two new species, P. gorczycai sp. nov. and P. herczeki sp. nov., are described and illustrated with 21 figures. Key words: Insecta, Hemiptera, Heteroptera, Reduviidae, Harpactorinae, Peyrierocoris, new synonym, new combination, new species, Madagascar
Introduction The subfamily Harpactorinae Amyot & Serville, 1843, with almost 300 genera and over 2000 species, is the largest subfamily in the family of assassin bugs (Reduviidae) (Maldonado Capriles, 1990). However, the representatives of this subfamily distributed in Madagascar have never been fully studied. There are only 23 genera of Harpactorinae recorded in Madagascar (Maldonado Capriles, 1990; Chłond & Junkiert, 2010; Chłond & Baňař, 2013) so far, and the newly described genus Peyrierocoris Chłond & Junkiert, 2010 belongs to a group of 11 genera distributed exclusively on the island. Vesbius Stål, 1865 is a small genus with 16 species described so far. Almost all of the known species (except one) are distributed in South East Asia, and only Vesbius seyrigi described by Villiers in 1970 has been recorded from Madagascar. An examination of type specimens as well as numerous specimens deposited in European collections clearly shows that this species does not belong to Vesbius but to the Peyrierocoris Chłond & Junkiert, 2010 and the subgenus Sicardicoris Chłond & Guilbert, 2012; consequently, a new combination is proposed to accommodate Vesbius seyrigi Villiers, 1970. Moreover, examination of unidentified materials from Madagascar deposited in the collection of the Muséum national d’Histoire naturelle, Paris, France, Národní muzeum, Praha, Czech Republic, and Koninklijk Museum voor Midden-Afrika, Tervuren, Belgium, revealed also specimens which belonged to two new species described in the present paper.
Material and methods The type specimens are preserved in the collection of the Muséum national d’Histoire naturelle, Paris, France (MNHN). External structures of dry-mounted specimens were examined using a stereoscopic microscopes Olympus SZX9 and Leica MZ16. All drawings were made using a camera lucida. Dissected genitalia were boiled in 10% KOH for 5 minutes to remove soft tissue, rinsed in distilled water, and dissected under a stereoscopic

microscope Olympus SZX9. Genitalia are stored in PVC microvials with glycerol, and attached on the pin with the dissected specimen. Measurements were made with an ocular micrometer under a stereoscopic microscope (Olympus SZX9) and are given in millimeters. Quoting the labels of specimens: (/) is used to divide data on different rows on the label, (;) is used to divide data on different labels, ([]) is used for author’s comments.

Taxonomy Genus: Peyrierocoris Chłond&Junkiert, 2010 Type species: Peyrierocoris (Peyrierocoris) mirabilis Chłond&Junkiert, 2010:34 (by original designation).
Diagnosis. Body medium-sized, slender, and shiny (Fig. 1). Head wide, with short and wide postocular region, distinctly downward clypeus, relatively large eyes and short antennifers (with apices directed frontally). Pronotum gradually expanded, apical lobe with distinct longitudinal suture. Hemelytra with straight margins on apical part of corium. Abdomen slender (males) or quadrangular (females). Posterior pronotal lobe rounded in posterior margin (Figs 21–23)), scutellum elevated in lateral view; median process of pygophore long with divided apex (Figs 6–8). Vesbius Stål, 1865 is similar to Peyrierocoris Chłond & Junkiert, 2010 only with respect to general body shape. It can be easily distinguished from Peyrierocoris by its short globular head (very short anteocular part of the head in dorsal view (Figs 30,31 )), with large eyes, smaller and more convex pronotum (Fig. 33), and a presence of coriaceus part of the hemelytra on membrane (in the basal part of apical internal and external cells) (Fig. 32).

Distribution. North Madagascar: Ampanefena, Nosy-Be—Lokobe Strict Reserve. Etymology. It is a pleasure to dedicate the name of this species to Jacek Gorczyca, the world specialist on Cylapinae and the supervisor of my PhD thesis. Comments. One female was collected on Nosy-Be Island as well as a second female deposited in the collection of Koninklijk Museum voor Midden-Afrika, Tervuren, Belgium (collected probably on the same island); these females have much clearer (yellowish) pronotum, clavus, and apical part of corium; moreover, the pale parts of the legs are red.
Discussion During the study of material from Madagascar deposited in the Muséum national d’Histoire naturelle, Paris, among unidentified material from Madagascar, a type specimens of V. seyrigii Vill. were checked. Examination of this material and comparison with the type specimens of other species of Vesbius deposited in the collection, confirmed that these specimens definitely does not belong to mentioned genus. Based on zoogeographical considerations— distributional data from the labels as well as information on the distribution of the genus Vesbius which has been reported in the catalog of Maldonao Capriles (1990) it was confirmed that the area of distribution of this genus is in South East Asia. Examination of all morphological characters clearly shows that this species does not belong to Vesbius but to Peyrierocoris Chłond & Junkiert, 2010. Besides the obvious differences like the distinctly more robust body and relatively small eyes placed in the middle part of the head in lateral view (Fig. 47), representatives of the genus Vesbius have very slender body and large eyes (relative to the size of the head) placed very near the anterior part of the head (Figs 46,47). Peyrierocoris differs from Vesbius by its distinctly different shape of the head (Figs 40–45). The anteocular part of the head in Vesbius is very short and distinctly rounded; the apical part of the antennifers reach or only slightly surpass the anterior margin of the eyes in dorsally (basal part of antennifers of Peyrierocoris are placed on anteocular part of the head, distinctly behind the anterior margin of the eyes in dorsal view (Fig. 46)). Apically on the femurs of Vesbius are three visible globular enlargements, which are absent in Peyrierocoris. One of the most important and most visible characters is the presence of coriaceus part of hemelytra on membrane (in the basal part of the apical internal and external cells of Vesbius) (Fig. 48); this character is absent in Peyrierocoris (Fig. 50). After examination of all morphological characters of both genera, it can be conclude that they seem not to be closely related. Examination of the morphological characters of the pronotum and scutellum between species described by Villiers (1970) and three species described by Chłond & Junkiert (2010) and Chłond & Guilbert (2012) (Figs 37– 39), as well as the shape and length of the median process of the pygophore (distinctly elongated (Figs 6–8)), confirmed that this species belongs to the subgenus Sicardicoris. With two subgenera Peyrierocoris Chłond & Junkiert, 2010, Sicardicoris Chłond & Guilbert, 2012, and only six known species: P (P.) guilberti Chłond & Junkiert, 2010, P.(P.) mirabilis Chłond & Junkiert, 2010, P.(S.) gorczycai sp. nov., P.(S.) herczeki sp. nov. P.(S.) niger Chłond & Guilbert, 2012 and P.(S.) seyrigi (Villiers, 1970)), is one of the smallest genus belonging to the subfamily Harpactorinae.
