Aedeagus in dorsal view, parameres elongated and with twisted base, greatly separated; in side view, the parameres are concave and extend beyond the posterior margin ( Figure 10(d), (e), (f)).   Type material.The typeseries is deposited at BMNH.

Width: 4.44–6.10 mm. Head: Frons with interocular tubercles between eyes, not connected by transverse carina; region between the tubercles almost flat and with deep points. Pronotum: Pronotum mesoanteriorly with little elevated tubercle, almost bidentate, which can be more or less developed; depression marked by points behind the tubercle. Disc with sparse points, unevenly distributed. Male terminalia: In dorsal view, parameres elongated and with twisted base, greatly separated ( Figure 10(d)); In lateral view, the parameres are concave and extend beyond the posterior margin ( Figure 10(f)). Sexual dimorphism: Males have weak, almost imperceptible punctuation and the setae are absent in the clypeus; well developed frons tubercle, while females have up to four setae in the posterior region of the clypeus and the rough and carenaded surface; underdeveloped frons tubercles. Remarks: Arrow (1913)described the species based on a series collected in Bahia, by Alexander Fry in 1860; a male specimen of the series was designated as a type.  Bacchus (1978)provided the following information about the type series: Holotype(male) Brazil: Bahia.  Paratypes, Brazil: ( 1 male, 4 females) same data as the holotype; 1 female Ceara-Mirim, Rio Grande do Norte( W. M. Mann); 1 female, Independência, Parahyba( Mannand Heath). The type series is deposited at BMNH.   Differential diagnosis.  Bolbapium parcepunctatumis morphologically similar to  B. borgmeieri,  B. boillyi sp. nov.,  B. caesum, B. howdeni, B. modestum, 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 a bituberculated projection. In addition, it is only possible to distinguish the species from  Bolbapium santanaorum sp. nov.by male terminalia and geographic distribution, with  B. parcepunctatumoccurring exclusively in the northeast of the country while  B. santanaorum sp. nov.occurs in the Central-West region, in the north of the southern part of the country and part of the northeast.  Geographical distribution.  Brazil( Bahia, Ceará, Paraíba, Pernambucoand Rio Grande do Norte).  Non-type material. 14 specimens.   BRAZIL: Bahia, without data ( 1♀ CEMT); Ubaíra, parc 32, 13°7 ʹ6”S, 39°41 ʹ24”W, 416mols, xi.2011, pitfall, C .M.P.
