Bolbapium howdeni Martínez, 1976: 542–546 (original description)
Diagnosis
Frons without transverse carina between the eyes, formation of interocular tubercles. Pronotum mesoanteriorly with curved structure towards the head, without angulations on each side of structure (Figure 6 (d)).
Type material. The type series are deposited at the MACN. It was possible to analyse the holotype from photo.
Holotype. ‘ BOLIVIA /Dep. Sta. Cruz/Prov. Ichilo/Buenavista/ Coll. Martínez //Oct: 949//; HOLOTYPUS [red rectangular label]; Bolbapium /howdeni/ ♂ /sp.nv./ A Martínez – DET – 76; Fichado’ (MACN-Em/1136).
Redescription
Body size: Legth: 5.91–7.47 mm. Width: 4.48–5.99 mm. Head: Frons without transverse carina between the eye, and presents interocular tubercle, one on each side, the base being wider than the apex; slight slope between the tubercles, marked by unevenly distributed points. Pronotum: Pronotum mesoanteriorly with curved structure towards the head, without angulations on each side of structure, and occupying more than half the interocular width. Disc sides with unevenly distributed points. Legs: Second and third pair of legs with adjacent spurs; both spiniform. The first spur is smaller than the first tarsomere and the second is larger. Male terminalia: In dorsal view, short and flat parameres (Figure 11 (d)). In lateral view posterior margin with rounded projection beyond the apex of the parameres (Figure 11 (f)). Sexual dimorphism: This species does not feature sexual dimorphism. Remarks: Martínez (1976) described the species based on two individuals from Bolivia. The type series consists of the holotype, collected by J.P.R. de Martínez and A. Martínez in the province of Ichilo, Buenavista, and the paratype, collected by A. Martínez in the province of Sara, Santa Rosa. Both are in the Argentine Museum of Natural Sciences, Buenos Aires, Argentina.
Differential diagnosis. Bolbapium howdeni is morphologically similar to B. boillyi sp. nov., B. borgmeieri; B. caesum, B. modestum, B. parcepunctatum, B. sampaioorum sp. nov., and B. santanaorum sp. nov. in not presenting the transverse carina forehead interconnecting the interocular tubercles. However, it is easily differentiated by presenting at the pronotum a curved structure towards the head, without angulations.
Geographical distribution. Brazil (Acre, Amazonas, Mato Grosso and Pará) and Bolivia (Santa Cruz).
Non-type material. 20 specimens.
