Pheidoleklaman sp. nov.: a new addition from Ivory Coast to the Afrotropical pulchella species group (Hymenoptera, Formicidae, Myrmicinae)

Abstract

In this study the taxonomy of the Pheidolepulchella species group is updated for the Afrotropical region and the new species P.klamansp. nov. described. It is integrated into the existing taxonomic system by an updated identification key for the whole group and an update of the known distribution ranges of its members. High quality focus stacking images are provided, with X–ray micro–CT scanned digital 3D representations, of major and minor worker type specimens.

Introduction

The ant genus Pheidole has recently been the focus of extensive taxonomic attention in the Malagasy region. Recent work mainly by Salata and Fisher (2020a, b, 2021) improved the taxonomy of the genus, creating eleven new species groups and adding dozens of new species. Much less attention has been paid to the massive undescribed Pheidole fauna in the Afrotropical region, remaining poorly known with dozens of species waiting to be described. The only modern attempt to organise the genus in the Afrotropics defined six species groups and assigned 67 valid species and subspecies to these groups based on qualitative morphology of the worker caste (Fischer et al. 2012). Fischer et al. (2012) also revised the P.pulchella group containing eleven species, of which seven were newly described. However, despite this work, most of the reorganisation of Afrotropical Pheidole taxonomy is still ongoing, since most valid species and many more undescribed ones need to be assigned to groups, and some new groups will need to be defined. More additions to Pheidole taxonomy are necessary to structure and catalogue their diversity in Africa to create a better base of understanding for the global radiations of Pheidole ants.

Taï National Park (TNP) is the last remaining major intact block of primary forest in West Africa. It was declared a UNESCO World Heritage Site in 1982 due to exceptional richness in fauna and flora. Based on several criteria including species diversity, endemism, presence of rare species and/or endangered and critical habitats, the TNP is considered a priority for the conservation of mammals, birds, amphibians, and invertebrates in West Africa (World Heritage 2022). A recent ant inventory by two of the authors (KG, LMK) in the Taï National Park at Ivory Coast yielded approximately 200 ant species and morphospecies (unpublished data), including undescribed taxa for various genera, including Bothroponera, Carebara, Monomorium, and Pristomyrmex, among others.

One of these new species is hereby described as Pheidoleklaman sp. nov. which we place within the P.pulchella group sensu Fischer et al. (2012). Since more material of the group has been sampled since Fischer et al. (2012), we take the occasion to update the illustrated identification key to incorporate the new species, as well as to provide distribution maps with updated distribution ranges for all species. The new species is described based on qualitative morphology of the worker caste, which we illustrate with high quality coloured focus stacking images and 3D models based on x-ray microtomography.

Materials and methods

Terminology follows Bolton (1994). Measurements follow Fischer et al. (2012).

Specimens were examined under a Leica MZ16A stereo microscope and measured at × 100. All images have been modified from originals and edited using GIMP (to compose the figures), IMAGEJ (to scale and add scale bars), and Polarr Photo Editor freeware (to sharpen and improve exposure and contrast). All micro-CT scans were performed at the Okinawa Institute of Science and Technology Graduate University (OIST), Japan, using a Zeiss Xradia 510 Versa 3D X-ray microscope operated with the Zeiss Scout-and-Scan Control System software (v. 11.1.6411.17883) and saved in DICOM format. 3D reconstructions of the resulting scan projection data were done with the Zeiss Scout-and-Scan Control System Reconstructor (v. 11.1.6411.17883) and saved in DICOM file format. Details on scanning parameters can be found in Table 5. Postprocessing of DICOM raw data was performed with Amira software (version 6.3). Virtual examinations of 3D surface models were performed by using the ‘volren’ function. The desired volume renderings were generated by adjusting colour space range to a minimum so that the exterior surface of specimens remained visible at the highest available quality. The 3D models were rotated and manipulated to allow a complete virtual examination of the scanned specimens in Amira, and in addition, exported in PLY format to be uploaded to the online 3D model platform Sketchfab (https://sketchfab.com).

Table 5.

Summary of micro-CT scanning parameters with resulting voxel sizes (optical magnification was 4 × and image size 1013 × 1013) for all three scanned specimens.

Subcaste	Specimen ID	Magnification	Voxel size (μm)	Exposure (s)	Power (W)	Voltage (kV)	Current (uA)
major	CASENT0764691	4 ×	5,7854	1,2	5,92	70	85
minor	CASENT0745509	4 ×	4,6952	0,6	4,01	50	80
minor	CASENT0764692	4 ×	5,3599	0,6	6,02	70	85

Images of shaded surface display volume renderings were made with the ‘snapshot’ function at the highest achievable resolution (usually at around 1900 × 893 pixels). Surface rendering rotational videos were created in Blender (v. 2.91, Blender Foundation, https://www.blender.org/). For optimal display, surface models exported from Amira were shaded ‘smooth’, scaled to ~ 1 m, illuminated with HDRi lighting, and rotated around their own z-axis based on specimens’ lateral views.

All specimens used in this study have been databased, and the data are freely accessible on AntWeb (2022). Each specimen can be traced by a unique specimen identifier attached to its pin. The Cybertype dataset provided in this study consist of the full micro-CT original volumetric datasets (in DICOM format), 3D surface models (in PLY formats), 3D rotation video files (in MKV format), all stacked digital colour images, and all image plates including all important images of 3D models for each species. All data have been archived and are freely available from the Dryad Digital Repository. In addition to the cybertype data on Dryad, we also provide freely accessible 3D surface models of the holotype and two paratypes of the new species on Sketchfab.

Diagnosis.

Pheidoleklaman is one of the four known yellow to orange species in the pulchella group, and appears closest to P.pulchella. It is easily separable from the other yellow to orange coloured species in the group as follows:

Minor worker: while P.pulchella has appressed scape pilosity, P.klaman possesses long erect setae on the scapes that are as long as or longer than the scape width. Separation from P.heliosa and P.christinae is based on size, with P.klaman clearly smaller (HW: 0.64–0.71) and with relatively longer scapes (SI: 182–189) than the other two species (HW: 0.73–0.83, SI: 143–174).

Major worker: the major of P.christinae is unknown. The absence of setae laterally on the head and the presence of clearly demarcated antennal scrobes separates P.klaman from P.heliosa. Separation from P.pulchella is also unambiguous, P.klaman clearly being smaller (HW: 1.65–1.75 vs 2.0–2.28 for pulchella), with more elongated head (CI: 88–93 vs. 98–104 in P.pulchella) and longer scapes (SI: 62–63 vs. 50–56). Sculpture is another separation character, with P.klaman being uniformly punctate from mesonotum to propodeum, versus more weakly and irregularly punctate sculpture in P.pulchella. In P.klaman the posterior third of face has faint incomplete longitudinal rugulae at most, reduced to weak, superficially reticulate punctures posteriorly, while in P.pulchella the posterior third of the face is longitudinally rugose and weakly to superficially punctate, changing to obliquely and weakly rugulose towards the posterior head margin.

Head longer than wide (CI: 88–93), frontal carinae and antennal scrobes conspicuous. Scapes relatively long for the group (SI: 61–63). Funicular segments slightly longer than wide, the last three more than twice as long as wide, apical one longer. Pronotum shape in dorsal view rhomboid, with clearly demarcated humeral angles. Promesonotal depression and metanotal groove deep. Primary mesonotal process conspicuous, stepping into a much smaller secondary one. Propodeum dorsally with two rugulae proceeding from the metanotal groove and continuing into the well-developed, long, apically curved spines (PSLI: 17–18). Petiole with very narrow anteroventral laminar process, postpetiole with large, rounded–triangular, anteriorly oriented ventral process, in dorsal view with hexagonal to ellipsoidal shape, and two small translucent flanges extending from medial corners to gaster.

Mandibles glassy smooth. Frons longitudinally rugose, with irregular pattern of moderately long to shorter rugae, spaces between rugae weakly punctate to almost smooth. Rugae grading weaker posteriorly with transverse incomplete anastomoses between them at vertex, fading from this point being gradually replaced by weaker rugulose–punctate sculpture becoming smooth at some patches. Pronotum smooth, rest of mesosoma strongly punctate, with some incomplete rugulae laterally, continuing at the base of the spines and propodeal declivity. Mesopropodeal suture with strongly demarcated longitudinal short cross–ribs. Petiole and postpetiole with the same punctuation as mesosoma, weaker to smooth dorsally. Anterior half of first gastral tergite superficially punctate, posterior half smooth.

Scape pilosity appressed. In full–face view, head without standing setae laterally.

Head longer than wide (CI: 79–83), with sides posterior of eye level weakly convex, slightly rounded towards posterior margin. Occipital carina conspicuous, medially and laterally. Mandibles relatively long (MDI: 85–88). Scapes very long (SI: 182–189), the longest in the whole pulchella group. All funicular segments significantly (~ 2 ×) longer than wide, apical three segments at least 3 × as long as wide. Mesosoma as described for the group, with moderately long, apically tapering, posteriorly curved spines (PSLI: 30–34). Pronotal humeri slightly peaked in lateral view, first and second mesonotal processes notorious and pronounced, each of these structures weakly marginate, or at least with some feeble rugulae. Metanotal groove broad and deep. Legs very long (FI: 208–220), relative to body size, the longest of all the pulchella group.

Head, mandibles, pronotum, coxae, legs, postpetiole, and gaster glassy smooth, except for some isolated strong reticulation between eyes and antennal fossae. Mesonotum and propodeum strongly punctate, both laterally and dorsally. Metanotal groove costate. Petiole from micropunctate dorsally to weakly punctate ventrally.

Long, orange erect to semi-erect setae sparsely distributed everywhere, including pro- and mesonotum, propodeum, petiole, postpetiole, and gaster, some longer than spine length. In full-face view, head laterally with semi-erect setae above and below eyes, some longer than eye diameter. Scapes with very abundant semi-erect setae, as long as scape width. Legs also covered with abundant semi–erect to decumbent pilosity.

Colour yellow to pale orange.

Derivatio nominis.

Identification key to P.pulchella group species

Measurements and indices are sometimes crucial for identification, so we have added detailed comparative measurements and indices for each species separated in yellow forms (Table 1 - minors, Table 2 - majors) and dark forms (Table 3 - minors,Table 4 majors).

–	Posterolateral lobes of head punctate, overlain by superficial rugulae (Fig. 8A, F)	8
8	Central rugulae on the head running to occipital line, sometimes broken, separated apart with wide spaces between them, some transverse rugulae may appear on the upper third of the head, but without creating a reticulum (Fig. 8F)	P.semidea
–	Central rugulae on the head not reaching the occipital line, close together and not leaving wide spaces between them and without transverse rugulae of any kind (Fig. 8A)	P.batrachorum

Pheidoledarwini

Republic of the Congo: Env. De Makaba (par Dimonika) (Mayombe) (L. Matile) (1 worker) [EY19812] MNHN.

Pheidoledea

The label for type locality of this species is “Lugombe” with no additional information and Santschi (1921) cites the locality as “Congo Belgue: Lugombe”. The current official type locality is Lugombe (DRC). Congo Belgue comprised several current countries, and Lugombe is a city in Uganda, close to the capital Entebbe, so, we propose to change the type locality from Lugombe (DRC) to Lugombe (Uganda). Our new citation is the first for DRC.

Democratic Republic of Congo: Secteur Nord: Mount Ngulingo, pres Nyamgaleke (Massif Ruwenzori (ex Albert NP)) 2500 m. H. Synave 17-18/08/1953 [RBINSFOR002196] RBINS

Pheidoleglabrella

Previously known from Western Central Africa (Cameroon, Central African Republic, Gabon and the DRC) (Fischer et al. 2012), our findings are first records for the following three countries and expand its distribution from Central to Western Africa:

Ghana: Kumasi, FORIG, near pond, 6.7150, –1.5291, 09/01/2019. Hand collected (Gomez, K.). Fragmented degraded forest (4 workers), ex soil [KG03925C01] KGAC; same data (1 worker), [KGCOL00993] KGAC.

Pheidolerebeccae

Only two series are cited for this species, the type series from Ivory Coast (Abidjan) and a series from the Atewa Forest in Ghana (Fischer et al. 2012). We found it in the Taï Forest National Park in Ivory Coast, where it seems to be abundant, nesting in rotten logs:

Ivory Coast: Montagnes District: Site 02 (Taï N. P.) 200 m, 5.8312, –7.3429 08–10/11/2019. Pitfall (Gómez, K., Kouakou, L.).
