(Hemiptera: Heteroptera: Reduviidae: Emesinae) is described based on four specimens collected in a cave of the Namoroka Karstic System, Madagascar, and deposited in the Collection of the Muséum National d Histoire Naturelle, Paris. The dorsal habitus as well as diagnostic characters of male and female genitalia are extensively illustrated and imaged. A key to species of the genus Mangabea Villiers, 1970 is provided and the degree of cave specialization of the new species is discussed. Key words: Heteroptera, Reduviidae, Emesinae, Mangabea, Madagascar, new species, cave, taxonomy Introduction Reduviidae is the second largest family of true bugs (Hemiptera: Heteroptera), which comprises of approximately 6,500 described species (Putshkov & Putshkov , Maldonado Capriles 1990). Given that Madagascar is considered one of the world s richest biodiversity hotspots, the fauna of Madagascan Reduviidae is particularly rich, comprising of 342 described species (Maldonado Capriles 1990 Labina & Kerzhner 2001, Villiers 1979). In recent years there has been a surge in studies describing new reduviid taxa from Madagascar (e.g. Chłond 2010a, 2010b, 2010c, 2011a, 2011b, 2014; Chłond & Junkiert 2010, 2011; Hwang & Weirauch 2010; Zhang & Weirauch 2011; Chłond & Guilbert 2012; Chłond & Baňař 2013; Chłond 2016; Chłond et al. 2016; Baňař et al. 2016; Forthman et al. 2016; Weirauch 2008), indicating that our knowledge on the island s reduviid fauna still remains far from complete. The Collartidini are a tribe of Emesinae of particular phylogenetic significance, as they have traditionally been considered as the sister-group to all other Emesinae (Wygodzinsky 1966). In addition, the biogeography of this tribe is interesting due to its strongly disjunct distribution, with species ranging from the Canary Islands, the Afrotropics, the Middle East, Sri Lanka and Taiwan (Rédei & Tsai, 2010; Wygodzinsky 1966). Concerning the Madagascan Collartidini, only one genus is known, among 28 genera and 99 species of Madagascan Emesinae (Villiers 1979). Mangabea was first described as a monotypic genus by Villiers (1970), initially including M. orientalis Villiers, 1970, until the description of a second species, M. barbiger Weirauch, 2008, almost 40 years later. The genus was erected by Villiers based on the distinctly elongated head with the anteocular part longer than the first visible labial segment and large eyes almost connected (holoptic) dorsally. These morphological characters differentiate Mangabea from other representatives of the tribe Collartidini. 372 Accepted by D. Redei: 10 Apr. 2018; published: 30 May 2018

2 Examination of unidentified specimens of Emesinae collected by Arnaud Faille during the 2016 expedition of the Muséum National d Histoire Naturelle (MNHN) in the Tsingy de Namoroka National Park, Madagascar, deposited in the MNHN, Paris revealed a remarkable undescribed species of Mangabea living in the caves of Namoroka. The type material is represented by three males and one female, while additional specimens comprise of two larvae. In this study, we describe the new species and also provide an identification key for the species of Mangabea. Material and methods The type material and the additional specimens are deposited in MNHN. External structures were examined using a stereoscopic microscope Nikon SMZ25 with a DS-Ri2 digital camera. All drawings were made using a camera lucida. Genitalia of the holotype male and paratype female were macerated in 10% KOH for 16 hours in 38 C or boiled for 10 minutes in 10% KOH, then rinsed in distilled water, and subsequently dissected under the stereoscopic microscope. Male genitalia were imaged at the Oxford University Museum of Natural History using a Leica M165c microscope with a Leica DFC490 camera, while stacked images were combined using Helicon Focus. Measurements are given in millimeters. All specimens were originally preserved in 70% ethanol, but were subsequently dried and pinned. The holotype male was observed and imaged by an environmental Phenom XL scanning electron microscope (SEM) (Phenom-World B.V., The Netherlands), which did not require destructive coating of the specimen. SEM imaging took place in low vacuum conditions at 10, 15 and 20 accelerating voltage with a secondary electron detector. Key to the species of Mangabea 1 Micropterous; anterior pronotal lobe distinctly enlarged (Fig. 2); posterior pronotal lobe reduced, not covering mesonotum; eyes reduced; 4 or more pairs of setae on ventral surface of head; legs extremely slender and long (Fig. 16) M. troglodytes sp. nov. - Macropterous; anterior pronotal lobe relatively short; posterior pronotal lobe covering mesonotum; eyes almost connected dorsally (holoptic); 3 or 2 pairs of setae on ventral surface of head Fascicle of stout setae on gena; anterior pronotal lobe not swollen, slightly smaller than posterior lobe; 3 pairs of setae on ventral surface of head M. barbiger Weirauch, Gena armed with 2 pairs of single setae; anterior pronotal lobe swollen, slightly longer than posterior lobe; 2 pairs of setae on ventral surface of head M. orientalis Villiers, 1970 Taxonomy Mangabea Villiers, 1970 Type species: Mangabea orientalis Villiers, 1970, by original designation. Revised diagnosis: Mangabea is recognized among the extant genera of Collartidini by moderate body size ( mm), elongate head, first visible labial segment not reaching anterior margin of eye, ventral surface of all visible labial segments or only second and third visible labial segments with dense vestiture, fore coxa with five or less spine-like setae. In macropterous forms basal cell pentagonal; discal cell long, more than three fourths of length between rm and tip of wing; crossvein proximal to rm vein present.

Distribution and ecology: West Madagascar: Namoroka Canyon (Fig. 26). The type locality is located in a remote area of Tsingy de Namoroka National Park. Grotte Canyon is a large cave with various galleries, most of them dry during the time of the year when the specimens were collected. Individuals of the new species were found in the deepest part of the cave, on a vertical surface of the cave wall covered by a prominent network of roots, together with the cave-inhabiting Cixiidae Typhlobrixia namorokensis Synave, 1953, a potential prey organism of this species. The fauna of this cave consists of a rich assemblage of troglobitic species, e.g. spiders, Opiliones, Blattodea (Nocticolidae) as well as two new species of Coleoptera (Staphylinidae) including the first cave beetle known from Madagascar (Löbl & Faille 2017, Faille & Lecoq in press). 378 Zootaxa 4425 (2) 2018 Magnolia Press CHŁOND ET AL.

Discussion Troglobitic adaptations in Emesinae. Although many species of Emesinae frequently inhabit caves, most are trogloxenic or troglophilic and have not evolved conspicuous adaptations for a strictly cave-inhabiting life style (e.g. e.g. reduction or loss of eyes) other than becoming paler than their free-living relatives (Pope 2013, Wygodzinsky 1966). The elongate body of most emesines is considered by some authors as a preadaptation (exaptation) for the cave niche, which might explain the repeated colonisation of caves by many emesine genera (reviewed by Wygodzinsky 1966 and Pope 2013). There are only three troglobitic emesine species, two pertaining to the Collartidini (Collartida anophthalma Espanol & Ribes, 1983 and C. tanausu Ribes, Oromi & Ribes, 1998) and one to the Ploiarolini (Nesidiolestes ana Gagné & Howarth, 1974) (Gagné & Howarth 1974, Ribes et al. 1998). Several traits of M. troglodytes sp.nov. may represent adaptations for a fully troglobitic life style and are shared with the other two troglobitic Collartidini: eyes reduced, pale cuticle, body and appendages much longer than freeliving congeners. The micropterous condition may not necessarily be a troglobitic adaptation, although many cave specialists (e.g. C. anophthalma, C. tanausu, many nocticolid cockroaches and dolichopodid crickets) are also characterized by the reduction or absence of wings. The enlarged anterior pronotal lobe, and the strip-like posterior pronotal lobe are correlated to microptery and the reduction of the flight apparatus, following a similar pattern to other heteropteran taxa with reduced wings (e.g. Davranoglou 2014). Additional ecological observations may shed light on the degree of cave-specialisation of the newly described species.

9 Relationships. The highly specialized morphology of M. troglodytes sp. nov. makes it difficult to elucidate its relationships to its free-living congeners, coupled with the fact that internal genitalia are known only from M. barbiger. However, the two species share raised lines on the endosoma (Fig. 12, el; Weirauch 2008), which may indicate a close relationship. However, if this trait is found in M. orientalis and other undescribed congeners (P. Baňař, unpublished) as well, it may suggest that this could represent an apomorphy for the genus, as the endosoma of other Collartidini is of very different form (e.g. Rédei & Tsai 2010, Wygodzinsky 1966).
