Ordo: Coleoptera
Familia: Staphylinidae
Genus: Bolitogyrus
Name
Bolitogyrus longistellus Brunke sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type locality
Panama, Panamá, km 7.5 El Llano-Cartí Road.
Type material
Holotype ♂ (SEMC): PANAMA: Panamá, km 7.5 El Llano-Cartí Road, 9°13'N, 79°05'W [in error, correct is 9.27, -78.96], 14 June 1996, 400 m [370 m in SEMC database], A. Gillogly [white printed label] / SM0016620 [white barcode label] / Holotype, Bolitogyrus longistellus Brunke, sp. n. [red printed label].
Diagnosis
Within the Bullatus Lineage: pronotum with three punctures in dorsal row (c.f. Fig. 7D); lateral margins of pronotum strongly converging anteriad (c.f. Fig. 7C); male sternite VII not distinctly emarginate; median lobe entire and distinctly narrowed in apical third (Fig. 22E); peg setae of paramere in elongate fields (Fig. 22F).
Description
Measurements ♂ (n=1): HW/HL 2.14; PW/PL 1.67; EW/EL 1.32; ESut/PL 0.76; PW/HW 1.16; forebody length 3.9 mm.
Similar to Bolitogyrus cornutus and differing only in the following: dorsal abdomen with tergites dark brown, paler apically; abdominal segment VIII and genital segment pale but tergite VIII with some basal darkening; metafemur with dark subapical band far from reaching apex; frons slightly more densely sculptured; base of head with posterior protuberances less pronounced, flattened; male pronotal protuberance strongly developed, produced into a ‘horn’, but smaller than in males of Bolitogyrus cornutus, apex rounded not truncate; lateral margins of pronotum strongly convergent; with three punctures in dorsal row of pronotum; median lobe entire but apical portion notched and very narrowly divided by median suture; in lateral view, median lobe slightly produced ventrad, narrowed to acute apex; paramere nearly reaching apex of median lobe; in lateral view, paramere slightly sinuate; in parameral view, median lobe strongly narrowed at apical third, converging slightly to narrow apex (Fig. 22E); paramere entire but with median suture, apex distinctly notched triangularly; in parameral view, paramere narrowed at midlength, dilated gradually toward to subapex, then gradually narrowed to notched apex (Fig. 22E); peg setae fields present as a pair of lateral rows 3-5 peg setae wide, widest basally (Fig. 22F); male sternite VII with small, very short, not flattened, glabrous area; male sternite VIII with transverse basal line not broken at middle, with slightly emarginate apex, impressed and glabrous in elongate, triangular area near emargination; male sternite IX with base more strongly asymmetrical, apex as narrow but not as deep (Fig. 24J). Female unknown.
Distribution
Figure 30D. Known only from the type locality in Panamá province, Panama.
Bionomics
The holotype was collected in tropical rainforest at 370 m in June.
Etymology
The species epithet means ‘long constellation’ and refers to the relatively long fields of peg setae (like a constellation of stars) on the paramere, a character that separates it from the similar Bolitogyrus brevistellus.
Comments
As far as known, Bolitogyrus longistellus is not sympatric with any other species of Bolitogyrus but is most similar in habitus to other members of the Cornutus Group. Without distributional information, it can be reliably separated only by the characteristic paramere.
