Aelocampsomeris Bradley, 1957 ( Figs. 1-8)

Aelocampsomeris Bradley,1957:74 (cat.;key)( type species: Campsomeris variegata Fabricius,1793 by designation ofBradley, 1964a. [= Campsomeris costalis Lepeletier, 1845 by original designation]) (as a subgenus of Campsomeris Guérin-Méneville, 1838); Bradley, 1964a: 106 (cat.).

Aelocampsomeris Argaman, 1996: 210 , 219 (cat.; key) (as a genus); Hanson, 2006: 616; Osten, 2005: 3 (cat.).

Diagnosis. Females: Very large, with entirely black vestiture and easily recognizable by their short acute black hind tibial spurs. First hind tarsomere cylindrical, differing from others tropical Campsomerini that have normally conical ones. Head and mesosoma always wholly black, sometimes having yellow marks on T1–T3 or metasoma entirely black. Transition between dorsal and posterior area of propodeum with a projecting point medially. Hypopygium subquadrate apically projected and with two heavy peg-like lateral teeth. Wings hyaline, hyaline with a fuscous costal border, yellow, or uniformly dark brown.

Males: Large and robust, less than females, but above average for others tropical Campsomerini. Posterior tibial spurs are normally black and slightly shortened. T1 and T2 with subapical punctures forming a transversal line. Vestiture is mostly white or yellowish, except in the last segments of the metasoma and in A. variegata , darker pilosity is broadly present. Strongly marked with yellow, as are Dielis dorsata Fabricius, 1787 and Lissocampsomeris wesmaeli Lepeletier, 1845 males, but easily differentiated from them by being larger and having short tibial spurs. Wings hyaline, their membrane bare beyond the cells. Some variations of the typical male coloration may occur.

Redescription. Females: Antennae, especially the flagellum, short and thick. Flagellomeres 2–6 twice wide as long. Clypeus pointed and with apical margin significantly wider medially than on the sides. Vertex and occiput generally with dense punctate, not entirely smooth and shiny. Upper half of mesopleuron with numerous large setigerous punctures, especially on its anterior half. Excavation of pronotum before tegula bordered by a sharp edge but no raised carina. Mesoplera with a distinct epicnemial ridge. Propodeum with a distinct, and sometimes, prominent tubercle. Lateral-dorsal area of propodeum without mirror.Posterior median area of propodeum impunctate. Lateral propodeal carina slightly exceeding beyond spiracle. Hind tibial spurs black, asymmetrical, and acute. Longer spurs of hind tibia short and stout, about 0.4 times length of the metatarsus. Scutum, scutellum, metanotum and propodeum slight to broadly spotted, not entirely smooth and shiny.Hypopygium (S6) subquadrate, with two heavily peg like lateral teeth. Abdominal terga matt. Setae entirely dark brown or black. Head and thorax always wholly black. Abdomen entirely black, or with T1 spotted or banded and, sometimes, with T2 and T3 also spotted. Wings variable: hyaline, hyaline with a fuscous costal border or uniformly dark. Length 24 – 35 mm.

Males: Tegument all black and with yellow markings present on the clypeus, pronotum, tegula , scutellum, metanotum, and propodeum in the medial and lateral areas, and on the legs; T1–T5 banded with yellow apically, bands can be interrupted from T2–T5. These marked areas may have some variations being more or less evident on each specimen. Longer spurs of hind tibia short and stout, about 0.4 times length of the metatarsus. Sternites with dense punctations from which brushes of erect bristles emerge, may occur from S4–S7 or at least S6–S7. Wings hyaline with a fuscous costal border, bare beyond the cells and with hair confined only to the costal margin, and the first submarginal cell with a clear comma shaped mark. There are reports of anomalous males with white or pale tibial spurs. Length 24 – 29 mm.

Cardo is rather elongated, gradually widening in its distal half.

Male genitalia: Pairedsquama, semi-cylindrical in shape, have a strongly reinforced basal opening. Each squama extends into a large paramere, which gradually widens, with its broadly rounded apex surpassing the apex of the penis valves. Paramere bears numerous bristles forming a ventral brush.Volsella are composed of two overlapping parts, separated by a transverse groove and, laterally, by a fairly deep notch. Basal part, or cupsis volsellaris, is wider than it is long and has a short lateral lobe bearing numerous brown cones.Similar cones are also found along the lateral edge of the distal part, called lamina volsellaris. These cones, more or less pointed or rounded at the apex, are articulated on a base and likely function as modified sensory structures. Cupsis volsellaris and the lateral half of the lamina volsellaris bear numerous bristles that form a shorter brush on the ventral side compared to the one on the paramere. Aedeagus is composed of two penile valves joined along the midline. Each penile valve has a long basal apodeme, directed obliquely towards the base of the genitalia; this apodeme serves as an attachment point for the retractor and protractor muscles of the aedeagus. Each penile valve is shaped like a blade, laterally flattened; in lateral view, its ventral edge shows about ten strong, pointed teeth.

Remarks. The genus name appears as both ‘Aelocampsomeris’ ( Bradley, 1957: 74) and ‘Aeolocampsomeris’ ( Bradley, 1957: 68) in Bradley’s work.Then, Bradley’s (1964a) subsequent usage of ‘Aelocampsomeris’ sets that as the correct spelling. Campsomeris has long been treated as a “dumping-ground” genus, containing very different taxa ( Añino et al., 2024). The different subgenera that compose it have profound morphological differences from each other, so that it seems necessary to treat them as genera on its own. Argaman’s work, although highly criticizable, offers some interesting proposals, notably the elevation of a certain number of subgenera to genus level.Like Argaman and Osten, it seems to us more correct to treat Aelocampsomeris as a genus level, so we adopt this position in this manuscript.

Distribution. Aelocampsomeris currently comprises three species that occur in the Neotropical Region, mainly the northern half of the South American continent, but occurring from the South of Mexico to southern Brazil ( De Saussure and Sichel, 1864; Bradley, 1945, 1957; Hanson, 2006; Rasmussen and Asenjo, 2009; Santos et al., 2015; Ramírez-Guillén et al., 2022; Añino et al., 2024).

Vestiture and pubescence predominantly yellowish and white, except for S7 and, sometimes, S6 having dark brown pilosity.

Remarks. Rare species, normally present in central-southern South America. Probably also confused with A.variegata in collections. Bradley and Betrem (1966) designated the lectotype of A. campestris , due to a different female species within Burmeister’s type series. There is a specimen misidentified by Osten in the Museum für Naturkunde, in Berlin (MFN) with the following labels: “Casapava Sella S.; Zool. Mus. Berlin; Campsomeris (Aelocamps.) campestris T.Osten det. Burm; MfN URI ”. This specimen probably belongs to the genus Pygodasis Bradley, 1957 . According to Burmeister, this species lives in large anthills on the ground (“Die Art lebt in den Erdhaufen der grossen Ameise”). No association between ants and Scoliidae wasps have been recorded in the scant literature about the biology of these wasps. To the best of our knowledge all scoliids are parasitoids of Scarabeoidea grubs and therefore it is likely that Burmeister’s observation was simply coincidental. However, it is worth mentioning that there are groups of coleoptera, such as the subfamily Cetoniinae and the tribe Cremastocheilini , strongly associated with anthills ( Puker et al., 2015), which could explain the association with Scoliidae .

Etymology. The word campestris comes from the Latin word campus, campester (neuter), which means “of the fields”. It’s used to describe something that normally occurs in fields or plains.

Distribution. Brazil (Amazonas, Brasilia, Mato Grosso, Minas Gerais, Rondônia).

Genitalia ( Fig.7c). Genitalia are similar in all three species. A.variegata and A. campestris are difficult to distinguish on the base of the genitalia. Unlike A. brethesi , these two species have distal part of the paramere more unpunctuated, aedeagus shorter than paramere, cardo without a three-branched reinforcement on the dorsal surface. A. variegata has a shorter, rounded aedeagus at the apex than A. campestris .

S2-S3 often with two thin yellow lateral bands, sometimes S4 as well. Wings hyaline or hyaline with a fuscous costal bar. Some reduction of the typical male coloration occurs; entirely black males are unknown. Vestiture and pubescence are predominantly white.

Remarks. According to Bradley and Betrem (1966) the type of A. variegata was supposed to be housed in Paris (MNHN) but was not found in that institution nor in the collections of Copenhagen ( Sweden) or Kiel ( Germany), which are known to contain types of Fabricius. The same author then designates the dorsal habitus illustration provided by Coquebert (1801, plate 13, Fig. 6) to represent the type.

Very common species. This species, especially the females, has a wide range of color variation. Therefore, we can identify some variations according to each colour combination that occurs.Overall, we can identify four types of variations in female (these “forms” have no taxonomic value, and intermediate individuals between these forms can be found):

var. fuscata : Mostly black and with dark bristles. T1 with two yellow spots. Dark brown wings with blue reflections; var.costalis : All body and bristles black. Wings hyaline or yellow with a fuscous costal border, sometimes with a clear comma-shaped mark on the bar; var. lucida : Dark and spotless body. Wings uniformly fuscous violet with green reflections; var.lativentris : Dark body with black bristles. T2 and T3 are spotted with yellow marks. Wings orangish brown.

Etymology. The word variegata comes from the Latin wordvariegatus, which means “variously coloured”.It’s used to describe something that has distinct markings of different colors, or is various, diverse, or varied.
