Macrocheilus taedatus Basilewsky, 1960 Figs. 11d, e, 12c, 14c Studied material. 1 female: “ Tanzania, 10/16.XII.99\near Mitundo, Dodoma prov. \ Werner & Lizler leg.” \\ “Collection\ Th. Assmann \ Bleckede, CAB” (yellow label)\\ “ Macrocheilus \ taedatus Bas. [h]\ det. Th. Assmann, 2008” [t] \\ “ Macrocheilus \ taedatus \ Basilewsky, 1960 ” [h]\ A. Serrano det. 2021” [t] [h]. Remarks. The species is distributed throughout Central and Oriental Africa (Basilewsky 1960; Häckel & Farkač 2013). The female specimen of Tanzania fits the original description of the species, allowing the description of the genitalia for the first time. Male genitalia. Drawings of median lobe in lateral and dorsal views and left paramere were provided by Basilewsky (1960, Figs. 2b, e). Taking into account these drawings the median lobe is slightly arcuate in the ventral edge, straight near apex (lateral view), not constricted between basal bulb and shaft, apical margin acuminated (dorsal view), presenting also a pair of large sclerotized stripes dorsally in the middle of the apical ostium. Female genitalia (Fig. 14c). Gonocoxite 1 subtriangular; gonocoxite 2 slender sickle shaped, apex sharp; dorsal surface slightly concave, covered with few minor setae, outer margin with 4 sub marginal setae and 2 marginal setae, apical half of inner margin with 6–7 setae, longitudinal median rib extending from apex to basal area without setae; ventral surface slightly convex, smooth.

Key to the Afrotropical (excluding Madagascar) Macrocheilus species An identification key for the Afrotropical species/subspecies is provided, including the new species. The Macrocheilus species /subspecies from Madagascar can be identified through Jeannel (1949) and Basilewsky (1953). Since the diagnostic external morphological characters are similar for males and females, the key can be used for both sexes. Macrocheilus basilewskyi and M. dorsalis are identified in any alternative dichotomic step 5 [larger species (length ≥ 10 mm) vs. smaller species (lengthM. labrosus (Dejean, 1831) - Elytra totally black, intervals with a very thin polygonal microreticulation; head and pronotum less densely punctured; posterior angles of pronotum rounded, without any expansion before the angles; male genitalia as in figure 3d..................................................................................................

Macrocheilus alluaudi Burgeon, 1937 Figs. 1f, 1g, 2e, 3d Studied material. 1 male: “ Republic of Congo \ Réserve Naturelle des Gorilles de\ Lésio Louna 17– 28.11.2017 \ Batéké Plateau H. Krahnstôver leg.” (Collection P. Sch ̧le, Herrenberg)\\ “ Macrocheilus \ alluaudi \ Burgeon, 1937 ” [h]\ “ A.Serrano det. 2021” [t] [h]. Remarks. The species was described as a variety of M. labrosus (Dejean, 1831) and later it was elevated to the subspecies level by Basilewsky (1960) due to its well differentiated external morphological characters, such as the absence of a big yellow spot in each elytron (Figs. 1f, 1g) and less dense punctuation on the head and pronotum. Later, it was considered a distinct species without any explanation for the change in taxonomic category (Lorenz 2005; Häckel & Farkač 2013). Taking into account the abovementioned external morphological differences, in addition to the slight different shapes of the labrum and of the median lobe of both forms (cf. Figs. 2e, 3d vs 6e, 7c), we follow the taxonomic treatment given by Lorenz (2005) and Häckel & Farkač (2013). Moreover, the pronotum hind angles in M. alluaudi are rounded while in M. labrosus are dentiform (cf. Figs. 1f, 1g vs Fig. 5i). In addition, the elytral intervals of the former species have a thin polygonal microreticulation not visible in the latter species. The species is known from Democratic Republic of the Congo (Basilewsky 1960) and Republic of the Congo (Lorenz 2021). Male genitalia (Fig. 3d). Median lobe very slightly different from that of M. labrosus, having a lesser rounded apex and the stripes are membranous in its inner sides; the left paramere is very similar in both species (cf. Figs. 3d and 7c). Distribution. Congo (Brazzaville), Democratic Republic of the Congo., Published as part of Serrano, Artur R.

However, the male aedeagi of all specimens are similar (Fig. 7d). Macrocheilus longicollis is recorded for Zambia for the first time. Male genitalia (Fig. 7d). Median lobe dilated in the median region, constricted between basal bulb and shaft, apex acuminated and slightly downward (lateral view), slightly acuminated (dorsal view), apical ostium with one pair of large scaled sclerotized stripes on dorsum, bending downwards, after backwards and finally directed upwards; left paramere large and rounded, without distal tooth.

Scutellum triangular, strongly setiferous punctured. Prosternum coarsely punctured, without microsculpture. Elytra (Fig. 1c) 1.8–1.9 times longer than wide (males: length 6.80–8.38 mm, width 3.68–4.55 mm; female: length 7.06 mm, width 3.89 mm), subparallel-sided, widening slightly towards the posterior third, not covering the last two tergites; only seven striae visible, the first six well-marked, the seventh faint, all slightly punctured and not reaching the base and the apex; intervals slightly convex, coarse setiferous punctures in two rows on 2 nd –7 th intervals and one row on 1 st interval, decumbent seta brown-yellowish sub-erected and directed posteriad; lateral margin rounded in the shoulders, ending in deep furrow densely punctuated towards the scutellum. Scutellar striae hardly visible through the deep punctures in the basal region of first interval. Basal pore present. Just behind the shoulders 3 pores on the very margin. Umbilicate series with about 22 to 29 pores, not interrupted in the middle although pores are more separated from each other in that area; 1 subapical pore shifted inward in the lengthening of the imaginary 8 th interval; apex with 4 extra pores, in the lengthening of the imaginary 7 th striae and 7 th, 6 th and 4 th intervals; apical transparent membrane extending from sutural angle to the lengthening of the imaginary 8 th interval. The longitudinal humeral orange band extends from the base to the median part, extending from the 2 nd striae to the lateral margin; the median dark brown transverse band stops very near the lateral margin, or reaches it, extending backwards to the ending of the imaginary 8 th striae; the oval sub transverse orange band in the last third reaches the apex and part of lateral margins; the dark brown basal marking reaches the basal margin towards the 5 th interval, extending, diamond-shaped, backwards, but not reaching the apex (Fig. 1c). Legs. Reddish-brown coloured; all tarsomeres pubescent, first three fore tarsomeres not dilated, fourth tarsomere slightly triangulate; fore tibiae on the outer edge with two blunt spines. Ventral surface.Almost all underside orange-brownish; whole underside, including abdominal sternites coarsely punctured and pubescent (yellowish color), except gula, ventral and lateral sides of neck. Pubescence of prosternum and proepisternum slightly erected and directed anteriad; pubescence of the remaining ventral sclerites dressed and directed posteriad. Elytral epipleura moderately punctured, pubescence dressed and directed posteriad. Male genitalia (Fig. 3b). Median lobe dilated in the middle of ventral area, apical lamella short, wide and subacuminated at apex (dorsal view), downward (lateral view), ostium with one pair of thin sclerotized stripes in the dorsal median region, bending laterally downwards; endophallus with several minor sclerites just behind the dilated region; left paramere longer than wide, straight, rounded at apex, a tiny tooth in postero-dorsal edge. Female genitalia (Fig. 4b). Gonocoxite 1 subtriangular; gonocoxite 2 slender sickle shaped, apex slightly sharp; dorsal surface concave, strongly setose, four setae on dorsal half basal inner side and other four on dorsal half subapical outer side, several minor setae in a slight submarginal ridge along the half outer side; ventral surface slightly convex, smooth with some minor pubescence. Intraspecific variation. The range of variability observed in M. philippeorum sp. n. (8 specimens) includes the darkness of the general colour of head+pronotum, the lateral extension of the median transverse dark brown band of elytra, reaching, or not, the lateral margin, extending more backwards, or not, or even in its middle width. There is some variability in the number of anterior submarginal setae of clypeus and in the number of umbilicate elytral pores (22 to 29). These values seem to be correlated with the elytral length (longer or shorter lengths correspond to larger or smaller values, respectively). There is also some variation in the location of the 4 apical extra pores, sometimes in the lengthening of the imaginary 8 th interval or 7 th striae and 7 th, 6 th and 3 rd intervals or even 3 rd striae. The medium lobe of aedeagus is very conservative, but in one male specimen there is an unusual asymmetry concerning the dorsal apical area of the left strip, having a sclerotized expansion towards left, not present in the other six males. Etymology. In a modest homage, this species is named in honour of two French entomologists namely Philippe Moretto (Association Catharsius, France), a well-known expert on African Scarabaeinae, who collected the Burkina Faso specimens and other Macrocheilus specimens here studied and the late Philippe Annoyer (1967–2020) (Muséum de Toulouse), who organized the Expedition Sangha 2012 to the Central African Republic. Remarks. The new species is more akin to Macrocheilus persimilis Basilewsky, 1970 and M. longicollis Péringuey, 1904 than to the other African species by the elytral colour pattern (cf. Fig. 1c vs Figs. 9b and 9c). However, Macrocheilus philippeorum n. sp. can be separated from the former species by the less transverse pronotum (cf. Figs. 1c and 9e), the less acuminate apex of median lobe (cf. Figs. 3b and 13a) and different shape of labrum (cf. Figs. 2c and 6b), and from the latter species by the less slender body shape, the bigger size, the more transverse pronotum (cf. Figs. 1c and 9b), the less securiform last maxillary palpomere, the narrower transverse dark brown band (cf. Figs. 1c and 9b) and different shapes of median lobe of aedeagus (cf. Figs. 3b and 7d) and labrum (cf. Figs. 2c and 10a). The new species differs from the remaining African species by elytra colour pattern and the median lobe shape, among other external morphological characters. Distribution.

Remarks. The species was originally described from Natal (D`Urban) (Republic of South Africa) (Péringuey 1896) (Fig. 9f). The MRAC specimens were determined by P. Basilewsky. The elytral black spot pattern of M. proximus is slightly similar to that of the M. basilewskyi, but the pronotum conformation and the aedeagus of both species are quite different (see Figs. 11‒12, 13‒16, 18 in Serrano 2000). The known distribution in Republic of South Africa and the new records for Democratic Republic of the Congo and Ethiopia points to a scattered distribution in Africa. Male genitalia. Drawings of median lobe in lateral and dorsal views and left paramere were provided by Serrano (2000, Figs. 15, 16). Median lobe short, slightly knee shaped at the base, dilated in the middle, apical lamella very short, slightly acuminated at apex (dorsal view), downward (lateral view), ostium with one pair of very large scaled and sclerotized stripes on latero-dorsal region, bending downward near apex (Serrano 2000, Fig. 15); left paramere rounded, slightly longer than wide, without a tooth in postero-dorsal edge (Serrano 2000, Fig. 16). Female genitalia (Fig. 14a). Gonocoxite 1 subtriangular; gonocoxite 2 sickle shaped, apex hardly pointed; dorsal surface concave, almost all covered with numerous setae, inner margin with eight setae, outer margin with a sub marginal setose longitudinal rib; ventral surface slightly convex, some minor setae on surface.

Remarks. The species is distributed throughout western Africa (Basilewsky 1970; Häckel & Farkač 2013). The male adult specimen studied fit very well the original description, including the aedeagus (Basilewsky 1970, Fig. 4a). The presence in Zambia extends its distribution faraway to southern Africa, being a new record for this country. Male genitalia (Fig. 13a). Drawings of median lobe in lateral and dorsal views and left paramere were provided by Basilewsky (1967, Fig. 4a). However, he did not make its description, saying that “est bien different chez les deux formes”, referring to the closer species Macrocheilus cruciatus (Marc, 1840). Median lobe largely dilated in the median region, slightly constricted between basal bulb and shaft, apex long, very acuminated and slightly downward (lateral view), slightly acuminated (dorsal view), apical ostium with one pair of thin scaled sclerotized stripes on middle region of dorsum, bending downward near apex, becoming membranous and ending in a very large sclerotized plate (Fig. 13a); left paramere longer than wide, rounded at apex, without distal tooth (Fig. 13a).

The adult male specimens examined fit very well the original description, including the median lobe conformation (see Basilewsky 1967). Male genitalia (Fig. 3f). A short description and drawings of median lobe in lateral and dorso-apical views of this species were provided in its original description (Basilewsky 1967, Figs. 2d, 3d). Additional characters of the median lobe, which were not given by this author, are the presence of one pair of scaled sclerotized stripes in laterodorsal region, dorsal opening of ostium too far backward and apex acute (dorsal view) (Fig. 3f). Moreover, the left paramere is ovoid shaped, with an expansion in the dorso-posterior edge (Fig. 3f). Distribution.

Remarks. The species was described from the southwestern region of Republic of South Africa (Cape Province) (Hackel & Farkač 2013). During a visit to MRAC, in 1992, we had an opportunity to check a female specimen of this species which was collected in the Kruger National Park (RSA, north-eastern provinces of Limpopo and Mpumalanga) (see studied material). Now, the study of male specimens allows providing the diagnosis of the genitalia. Macrocheilus dorsalis is recorded for Tanzania and Zambia for the first time. Male genitalia (Fig. 7a). Median lobe straight, slightly constricted between basal bulb and shaft, apex roundacuminated and slightly downward (lateral view), apical margin rounded and acuminated (dorsal view), apical ostium with one pair of scaled sclerotized stripes on dorsum which extends backward, endophallus without large curled inward sclerotized plates; left paramere large and rounded, without any distal tooth.

It is easily recognized and differentiated from the other species of the genus by the twisted barrel shape of the last article of maxillary palps plus the orange rounded spot in the end of the middle of the first half of elytra (Fig. 5i). Macrocheilus alluaudi presents the same shape of the last maxillary palpomere, but not the orange rounded spot in the elytra, which is totally black (see also the remarks on this species). The study of males and one female allowed the description of both genitalia for the first time. Macrocheilus labrosus is recorded for Burkina Faso and Central African Republic for the first time. Male genitalia (Fig. 7c). Median lobe long and straight, constricted between basal bulb and shaft, apex largely rounded (dorsal view), straight (lateral view), ostium with one pair of large scaled and slightly sclerotized stripes on dorsum, bending downwards and backwards, increasing sclerotization and ending in a plate directed upwards; left paramere large and rounded, without any distal or marginal tooth. Female genitalia (Fig. 8d). Gonocoxite 1 subtriangular; gonocoxite 2 very largely sickle shaped, apex acuminate-rounded; dorsal surface concave, almost all covered with numerous setae, several setae inserted on an outer sub marginal longitudinal rib, subapical inner margin with five setae; ventral surface convex, smooth.

Thorax. Pronotum cordiform (Fig. 1b), transverse, about 1.5–1.6 times wider than long (males: length 1.47– 1.60 mm, width: 2.29–2.43 mm), maximum width before the middle length; surface covered with coarse punctures, being more dense throughout the discal surface; each puncture bear a long and fine brown-yellowish seta, intervals smooth; anterior angles rounded, anterior margin arcuate; posterior margin straight in the middle, strongly rightangled sinuate towards the posterior angles which bear a tooth and a long seta; posterior margin not margined, anterior margin margined in the middle, lateral margins with complete and distinct margination since the anterior angles, reaching the posterior angles, slightly sinuate just anterior to posterior angles, forming a short tooth just before the angles, a long seta behind the widest part of pronotum, anterior angles with some large bristles; anterior transverse sulcus not distinct, pronotal base with a pair of longitudinal deep foveae separated by a median sulcus in a flat and depressed area that reaches the posterior margin. Scutellum triangular, strongly setiferous punctured. Prosternum coarsely punctured, without microsculpture. Elytra (Fig. 1b) 1.6 times longer than wide (males: length 5.87‒6.07 mm, width 3.68‒3.78 mm), subparallelsided, widening slightly towards the posterior third, not covering the last two tergites; only seven striae visible, well-marked, all punctured and not reaching the base and the apex; intervals slightly convex, almost plane, coarse setiferous punctures in three rows on 2 nd ‒7 th intervals and two rows on 1 st interval, decumbent seta brown-yellowish sub-erected and directed posteriad; lateral margin rounded in the shoulders, ending in deep furrow densely punctuated towards the scutellum. Scutellar striae visible through the deep punctures in the anterior region of first interval. Basal pore present. Umbilicate series with about 25 (holotype) and 30 (paratype) pores, not interrupted in the middle although pores are more separated from each other in this area; 1 subapical pore shifted inward in the lengthening of the imaginary 8 th striae; apex with 4 extra pores, 2 in the lengthening of the imaginary 8 th striae and of 7 th striae, respectively, and 2 in the lengthening of the 6 th and 3 rd intervals; apical transparent membrane extending from sutural angle to the lengthening of the imaginary 8 th interval.

Median lobe short, not knee shaped at the base, slightly dilated behind the middle, apical lamella short, acuminated at apex (dorsal view), downward (lateral view), ostium with one pair of scaled and sclerotized stripes on latero-dorsal region, bending downward near apex, becoming membranous and ending in a very large curled inward sclerotized plate; left paramere slightly longer than wide, rounded at apex, with a tooth in postero-dorsal edge. Female. Unknown. Intraspecific variation. There is variability between the holotype and paratype in the number of pores of umbilicate series (25 vs. 30). Etymology. This species is named in honour of Arnošt Kudrna (Ceské Budejovice, Czech Republic), a wellknown specialist in Cicindelidae, who collected the Benin specimen and other Macrocheilus specimens here studied. Remarks. Taking into account the general shape of median lobe of aedeagus (Fig. 3a), Macrocheilus kudrnai n. sp. seems to be close to M. clasispilus Basilewsky, 1967 (see Basilewsky 1963, Figs. 2b, 3b vs. Fig. 3a, this work). However, some external morphological characters allow separating both species. The pronotum of the new species is slightly less transverse than that of the latter species (1.52–1.56 vs. 1.65–1.67). On the other hand, just anterior to the posterior angles of pronotum, a short tooth occurs in the former species, but it is not present in the latter species (cf. Figs. 1b and 5c). In addition, the elytral intervals of Macrocheilus kudrnai n. sp. are almost plane while the intervals of M. clasispilus are subconvex. The new species also exhibits a more or less similar general shape pattern of the median lobe (in lateral and dorsal views) as in Macrocheilus biguttatus (Reiche, 1832) and Macrocheilus dorsalis Klug, 1834, but is slightly different (cf. Figs. 3a, 3e and 7a). Moreover, the general body colour of the new species and these two species is quite different. Concerning M. dorsalis, its left paramere does not present a tooth at the postero-dorsal edge. The new species differs from the remaining African species by the median lobe shape, among other external morphological characters. Distribution.

Remarks. The species was known only from Republic Democratic of the Congo (Burgeon 1937; Häckel & Farkač 2013). In the Angolan females studied, the head and pronotum are blackish, contrarily to the original description (brownish) (see Figs. 9h, i). However, both specimens fit very well all the remaining morphological characters of the holotype, including the special conformation of mentum of M. quadrinotatus [see final comment on this character provided by Burgeon (1937)]. The female adult specimen of Darfur was determined by P. Basilewsky. The male genitalia is unknown, but the collection of female specimens allowed the description of female genitalia for the first time. The known distribution in Democratic Republic of the Congo and the new records for Angola and Sudan indicates a scattered distribution in Africa. Female genitalia (Fig. 14b).

Etymology. This species is named in honour of Peter Scḩle (Herrenberg, Germany), a well-known specialist on tiger and ground beetles of Africa who has strongly collaborated with us and kindly provided all the specimens of this new species. Remarks. The new species is more akin to Macrocheilus scapularis (Reiche, 1843) and M. allardi Basilewsky, 1957 than to the other African species by the elytral colour pattern (cf. Fig. 1d vs Figs. 11a and 1e). Macrocheilus schuelei n. sp. can be separated from the former species by the more transverse pronotum, the posterior angles of pronotum slightly obtuse and rounded at apex (acute and slightly rounded in M. scapularis), the legs totally brown (tibiae blackish in M. scapularis) and different shape of labrum (cf. Figs. 2d and 12a) and of median lobe of aedeagus (cf. Figs. 3c and 13b). The new species differs from M. allardi by the shorter body, the head, pronotum, scutellum, mouthparts and legs colour (cf. Figs. 1d and 1e), a lesser securiform shape of the last palpomere of maxillary palps, more transverse and different shape of pronotum and of labrum. Macrocheilus schuelei n. sp. differs from the other African species of this genus by the elytral colour pattern and the median lobe shape, among other external morphological characters. Distribution.

Remarks. The species is polytypic, the nominotypical subspecies is spread over southern Africa (Angola, Democratic Republic of the Congo, Kenya, Mozambique, Republic of South Africa, Tanzania, Zimbabwe) (Basilewsky 1960; Häckel & Farkač 2013). Macrocheilus viduatus katanganus was originally described from several localities of the former Belgian Congo (= Democratic Republic of the Congo) and north of Rhodesia (= Zambia) (Basilewsky 1960) based on the well differentiated colour of legs and antennae (black in the nominotypical subspecies vs. reddish brown in M. viduatus katanganus). All the adult specimens studied (e.g. Fig. 11g) have the legs and antennae reddish brown and hence belong to this subspecies. The species is very similar to M. bimaculatus, both presenting distinct microreticulation, extremely fine, in the elytral tegument. However, the aedeagus of both species are very different, allowing their segregation (see Serrano 2000, Figs. 1, 2 and Fig. 13d, this work). Macrocheilus viduatus katanganus is recorded for the Republic of South Africa for the first time. Male genitalia (Fig. 13d). Median lobe slightly dilated in the median region, slightly constricted between basal bulb and shaft, apex acuminated and very slightly upward (lateral view), rounded (dorsal view), apical ostium with one pair of large scaled sclerotized stripes on dorsum; left paramere large and rounded, without distal tooth. Female genitalia (Fig. 14d). Gonocoxite 1 subtriangular; gonocoxite 2 sickle shaped, apex sharp; dorsal surface slightly concave, covered with numerous setae, several setae (9–10) near the outer margin on a sub marginal longitudinal rib, apical half of inner margin with 3 setae; ventral surface slightly convex, smooth.

Four new species of Afrotropical ground beetles of the genus Macrocheilus Hope, 1838 (Coleoptera, Carabidae) are described: M. assmanni n. sp. from Tanzania, M. kudrnai n. sp. from Benin and Burkina Faso, M. philippeorum n. sp. from Benin, Burkina Faso and Senegal and M. schuelei n. sp. from Central African Republic. An annotated checklist of 19 Afrotropical species and subspecies is provided, including data on general distribution and new distribution records at country level. Further, a dichotomic key is made available for the identification of the Afrotropical (excluding Madagascar) Macrocheilus species and subspecies and diagnosing morphological characters of both males and females are illustrated.

The Gorongosa National Park (Mozambique) is one of the most emblematic protected areas in Africa, well known for its vertebrate biodiversity and restoration ecology efforts following the Mozambican civil war in 1992. The invertebrate biodiversity of Gorongosa National Park is still poorly studied, although the scarce information available indicates the existence of a rich number of species, particularly ground-beetles. The study of Caraboidea beetles is key for designing conservation practices since they are frequently used as biodiversity and ecological indicators and provide valuable information to help decision making. Therefore, the diversity assessment of Caraboidea beetles using standardized methodologies, can be used to quantify the effects of climate change in areas identified as vulnerable to antropogenic pressures, such as the Gorongosa National ParkWe report the occurrence of five tiger beetles (Cicindelidae) and 93 ground beetles (Carabidae) species/morphospecies in Gorongosa National Park from a field survey funded by the ECOASSESS project. Sampling was performed in the four main habitat types present in the park (miombo tropical forest, mixed dry forest, transition forest and grasslands) between October 25th and November 25th. In this sampling window, the turnover of Caraboidea species from the dry season to the wet season was recorded for the first time. Twenty-seven species of ground-beetles are new records to Mozambique, including three new subgenera and two new genera. Additional information on species phenology and habitat preferences is also provided.
