Diagnosis. Females of this new species are similar to those of G. unilobata ( Redtenbacher, 1908) but differ by the somewhat more elongate shape (mesothorax 7.2x longer than prothorax vs. 6.5x longer in unilobata ), wholly smooth mesonotum (unevenly granulose in unilobata ), more elongate head ( Fig. 21H View FIGURE 21 ), apically narrowed and acute apex of the subgenital plate ( Figs. 22 View FIGURE 22 G-J; rather broadened and rounded in unilobata ) and smaller sub-apical protrusion of the two outer ventral carinae of the meso- and metafemora (rounded and multi-dentate in unilobata ). Males are readily recognised and distinguished from all other members of the genus by the very distinctive colouration, having a bright red medio-longitudinal marking or streak on the mesonotum and metanotum ( Figs. 20D View FIGURE 20 , 22M View FIGURE 22 ).

Etymology. The name refers to the bright red longitudinal median stripe on the meso- and metanotum of ♂♂ this new species ( Fig. 20D View FIGURE 20 ).

Description. ♀♀ ( Fig. 22B View FIGURE 22 ): Moderately sized (body length including subgenital plate 140.0–151.0 mm) and slender for the genus with an elongate-oval, unarmed head, smooth thorax, unarmed legs and slender basitarsi. Dorsal body surface wholly smooth, except for a few small granules along lateral margins of mesonotum and on mesopleurae. General colour of the two specimens at hand pale buff to ochre, the buff specimen with a faint olive wash (both specimens have apparently been provisionally stored in ethanol, which has caused discolouration). Eyes and antennae rather drab.

Head ( Fig. 21H View FIGURE 21 ): Elongate-ovate, widest at the eyes, slightly narrowing toward the posterior and about 1.3x longer than wide; vertex very weakly rounded and with a slightly impressed coronal line. Area between the eyes weakly raised and with a shallow, gently curved transverse furrow behind. Frons with a C–shaped impression between the bases of the antennae. Eyes small, weakly projecting and circular in outline, their diameter contained 2.4x in length of genae. Antennae reaching to abdominal segment III. Scapus strongly compressed dorsoventrally, carinate laterally with both lateral margins very gently convex and 1.5x longer than wide. Pedicellus almost round in cross-section, slightly more than half the length of scapus and weakly constricted at the apex. III somewhat longer than pedicellus, notably slenderer and gradually narrowing towards the apex.

Thorax: Pronotum somewhat shorter and notably narrower than head, the anterior portion somewhat widened and the median portion distinctly narrowed with the lateral margins concave; about 1.4x longer than wide. Transverse median sulcus moderately impressed, gently curved with the median part straight and not just reaching to lateral margins of segment; the medio-longitudinal line somewhat impressed over complete length ( Fig. 21H View FIGURE 21 ). Mesothorax 7.2x longer than prothorax and very slightly narrowing in the anterior on third. Metanotum about half the length of mesonotum, rectangular and 3.6x longer than wide; meso- and metanotum with a fine longitudinal lateral carina and a row of small granules close to lateral margins. Meso- and metapleurae with fine and uneven medio-longitudinal carina, which is supplied with a few granules on mesopleurae. Mesosternum sparsely and minutely granulose in anterior portion.

Abdomen: Median segment less than half the length of metanotum with lateral margins weakly concave and about 1.5x longer than wide. Segment II notably longer than median segment, III–VI longer than II and roughly uniform in length, VII about as long as II and narrowing towards the posterior. II about 2.25x and III–VI on average 3x longer than wide. Praeopercular organ very indistinct and merely formed by a very a shallow posteromedian swelling on sternum VII ( Figs. 22J View FIGURE 22 , 85B View FIGURE 85 ). Tergum VIII about two-fifth the length of VII, as wide as posterior part of VII, rectangular and 1.5x longer than wide. IX somewhat narrowing towards the posterior, scarcely longer than wide and about three-quarters the length of VIII. Anal segment about as long as IX with a fine medio-longitudinal carina dorsally, somewhat narrowing towards the posterior and the posterior margin straight with the outer angles obtusely rounded. Epiproct small, roundly triangular and somewhat projecting over posterior margin of anal segment. Cerci small and narrowing towards an obtuse apex. Gonoplacs spatulate with the dorsal margin concave in the median section, strongly compressed laterally, gradually narrowing towards and obtusely truncated apex and slightly projecting beyond anal segment ( Figs. 4B View FIGURE 4 , 22G View FIGURE 22 ). Gonapophyses VIII slender and somewhat projecting beyond apex of gonoplacs ( Fig. 4B View FIGURE 4 ). Subgenital plate long, naviculate with the lateral margins strongly up-curved and gradually lowering towards the apex; in dorsal aspect with a distinct narrowing medially and the posterior portion somewhat widened before it narrows towards a rather acutely triangular apex ( Fig. 22H View FIGURE 22 ); the basal portion flattened and with a distinct, lamellate carina laterally.

Legs: Fairly long and slender for the genus; wholly unarmed except for a small, obtuse sub-apical tooth on the two outer ventral carinae of the meso- and metafemora. Profemora about as long as mesothorax, mesofemora about as long as metathorax, metafemora projecting over posterior margin of abdominal segment IV and metatibiae reaching to segment VIII. All basitarsi slender and ± as long as the remaining tarsomeres taken together.

♂♂ ( Fig. 22D View FIGURE 22 ): Medium to large (body length 74.0– 97.8 mm) and moderately slender for the genus with very distinctive colouration. Head, prothorax, median segment, abdomen, all coxae and legs basically drab and occasionally with a slight olive wash; abdomen occasionally pale ochre to buff (paratype in MZUSP) and the median segment sometimes with a greyish blue wash (e. g. in the holotype). Posterior margin of all abdominal terga including the median segment black. Meso- and metanotum and pleurae pale greyish blue to turquoise; meso- and metanotum each with most of the dorsal surface bright red. Meso- and metasternum dark yellow. Eyes ochre. Antennae reddish brown and gradually becoming brown towards the apex .

Head ( Fig. 21M View FIGURE 21 ): Shape and proportions generally as in ♀♀. Eyes notably larger although, strongly projecting and their diameter contained 1.5x in length of genae. Antennae almost reaching to apex of abdomen. Scapus oval in cross-section and just weakly compressed dorsoventrally; the lateral margins straight and roughly parallel-sided. Pedicellus and segment III as in ♀♀.

Thorax: Pronotum basically as in ♀♀ but the lateral margins less distinctly concave and the transverse median sulcus less pronounced. Mesothorax narrower than prothorax and uniform in diameter except for a slight widening of the anterior and posterior portions; 7.5x longer than prothorax. Metanotum less than 0.6x the length of mesonotum and weakly constricted medially; meso- and metanotum with a very fine medio-longitudinal line and a lateral row of minute granules parallel to lateral margins. Meso- and metasternum with a weakly defined medio-longitudinal carina.

Abdomen: Median segment about one-third the length of metanotum, slightly widening in the posterior half and the lateral margins gently concave; about 3.3x longer than width of anterior margin. Segment II 1.5x longer than median segment, III–V roughly uniform in length, VI and VII decreasing in length with VII shorter than II; II 3.75x and V about 4.5x longer than wide. Segments II–VII roughly uniform in diameter, but all weakly constricted medially and VII somewhat widening in the posterior portion. Terga VIII–X as a unity scarcely longer than VII but notably broader than all preceding segments. Tergum VIII very short with posterior portion inflated and the anterior portion constricted, distinctly trapezoidal in dorsal aspect with posterior margin considerably wider than anterior margin; lateral surfaces with a distinct and obtuse, gently curved longitudinal bulge. IX almost 1.5x longer than VIII, weakly narrowing towards the posterior, slightly longer than wide and the lateral margins somewhat deflexed and angular posteriorly. Anal segment much shorter than IX, strongly descendant towards the posterior but somewhat cucullate in lateral aspect ( Fig. 23D View FIGURE 23 ); in dorsal aspect basically trapezoidal with the lateral margins somewhat rounded, the posterior margin with a shallow median emargination and the outer angles obtusely swollen ( Fig. 23E View FIGURE 23 ). The swollen outer angles ventrally set with a few small black denticles ( Fig. 23F View FIGURE 23 ). Epiproct minute, roundly triangular and downward directed. Vomer basically triangular with a short but acute terminal hook. Cerci almost as long as anal segment, round in cross-section with a club-shaped apex and only the apical portion gently arcuate. Poculum large, bulgy, somewhat higher than tergum IX ( Fig. 23D View FIGURE 23 ), roundly rectangular in lateral aspect and carinate medio-longitudinally in the vertical posterior portion; the posterior margin triangularly protruded medially with a minute median indention and almost reaching to apex of anal segment ( Fig. 23F View FIGURE 23 ).

Legs: All long, slender and unarmed except for a minute sub-apical tooth on the two outer ventral carinae of the meso- and metafemora. Profemora almost as long as head, pro- and mesonotum taken together, mesofemora almost as long as mesothorax, metafemora reaching to posterior margin of abdominal segment V and metatibiae projecting greatly beyond apex of abdomen. Basitarsi slender and very elongate, all notably longer than remaining tarsomeres combined.

Eggs. There are four eggs extracted from the abdomen of one of the ♀♀ in the collection of ANSP. These are glued to a small piece of cardboard on the specimen’s pin. Since they are not fully developed, only a brief characterisation is provided here.

Fairly small (capsule length 2.8 mm), notably longer than wide, oval in cross-section and higher than wide with the anterior portion of the dorsal surface angular and distinctly concave. Capsule surface coriaceous. Micropylar plate oval, positioned medially on dorsal egg surface and a little less than half the length of capsule. Outer margin of plate somewhat raised and the median portion with an obtuse longitudinal bulge. Operculum missing but anterior opening almost circular in outline. Colour buff, the outer portion of the micropylar plate dull straw-coloured.

Large (capsule length> 4.0 mm), roundly angular in lateral aspect with the anterodorsal portion convex and roundly angular, the lower half somewhat narrowed and the polar area flattened; oval in cross-section. Capsule surface wholly covered with irregular protuberances, ridges and bulges with areas in between distinctly impressed. Micropylar plate slightly displaced towards the posterior, pear-shaped with the posterior portion widened and notched posteromedially and ± half as long as capsule; outer margin ± inflated. Surface of micropylar plate minutely granulose and flat to weakly convex. Micropylar cup small and bowl-shaped. Median line distinct but short and not reaching to polar area. Operculum almost circular and with a large, hollow capitulum that is formed by lamellate extensions of the outer margin. Height of capitulum variable and up to more than half of capsule length. Colour dark grey or brown with the impressed areas of the capsule darker. Micropylar plate dark brown to black. Capitulum straw, yellowish or orange.

Etymology. The name is a combination of “ globus ” (lat. = globose) and the Greek κραΝΊΟΝ or cranium (= skull) used as an epithet to refer to the strongly globose to almost spherical head. Feminine.

Differentiation. Globocrania gen.n. is morphologically similar and apparently closely related to Phanoclocrania gen. n. and Otocrania Redtenbacher, 1908 but differs from both genera by the genital morphology of ♂♂. All three genera share a ± distinct longitudinal median carina or keel on the ventral surface of the thorax, globose and often prominently armed head, black longitudinal median line or stripe on the pronotum and dorsally raised or lobed basitarsi of both sexes. Males of Globocrania gen. n. however are characteristic for the long anal segment, that is strongly widened in the posterior portion and the widest of all abdominal segments, the very slender and digitiform vomer and small, rather flat and scoop-shaped apically bidentate or bilobate poculum ( Figs. 95N–O View FIGURE 95 ). Females differ from those of both genera by the distinctly dentate or spinose meso- and metapleurae ( Figs. 24D–F View FIGURE 24 ) as well as the two longitudinal, parallel rows of tubercles on the meso- and metasternum ( Figs. 86A–B View FIGURE 86 ). For a more detailed differentiation from these two genera see table 8 below.

Comments. Members of this new genus have previously been placed either in Otocrania Redtenbacher, 1908 or Bostra Stål, 1875 (= Phanocloidea Zompro, 2002 ). Unfortunately, there has been some confusion with the authority of this new genus, that was caused by the preliminary use of the name by Conle et al. (2011: 59). Brock & Büscher (2022: 512) therefore listed the genus as “ Globocrania Hennemann & Conle, 2022 ” but unfortunately there has been massive delay of the present work, which now formally describes Globocrania as a new genus. Hence, the authority should be referenced to this current publication.

Distribution ( Fig. 102B View FIGURE 102 ). The four known species of this genus are restricted to the Atlantic Forest (Portuguese Mata Atlântica) along the Atlantic coast of Brazil between the states of Bahía in the north and São Paulo in the south. Biogeographically, this corresponds to the Paraná subregion of the Neotropical Region, comprising the three biogeographic provinces termed Brazilian Atlantic Forest, Paraná Forest and Araucaria angustifolia Forest (see Morrone, 2006: 472, 480, fig. 2).
