Genus: Bolitogyrus
Name
Bolitogyrus nigerrimus Yuan et al., 2007 – Wikispecies link – Pensoft Profile
- Bolitogyrus nigerrimus Yuan et al., 2007: 150.
Type locality
Lianhuaping, Leigong Shan, Guizhou, China.
Type material
Bolitogyrus nigerrimus Yuan et al., 2007.
Holotype (♂, SNUC). Lianhuaping, Leigong Mt., Guizhou Prov., alt 1450-1500 m, 15-IX-2005, Zhu li-long leg. [printed] / “[HOLOTYPE]” Bolitogyrus nigerrimus, Yuan, Zhou, Li, & Hayashi, 2007, SHNU Collections [red label] / AJB0000460 [identifier label].
Paratype (♀, SNUC). Same data as holotype, AJB0000461.
Diagnosis
Among the members of the Electus Group: many head punctures confluent (Fig. 3F); elytra not metallic blue-green; median lobe in lateral view with distinct but small lateral teeth, with small subapical expansion (Fig. 9I); paramere distinctly longer than median lobe, weakly constricted in apical fourth (Fig. 9J), with peg setae at middle, not elevated on ridge, medial group not extended basad of marginal group (Fig. 9K).
Redescription
Measurements ♂ (n = 1): HW/HL 1.27; PW/PL 1.25; EW/ EL 1.23; ESut/PL 0.89; PW/HW 1.10; forebody length 4.5 mm.
Measurements ♀ (n = 1): HW/HL 1.29; PW/PL 1.28; EW/ EL 1.23; ESut/PL 0.89; PW/HW 1.13; forebody length 5.0 mm.
Similar to B. electus and differing only in the following: palpi entirely pale; tibia with distal half yellowish-brown, paler than dark apical portion of femur (Fig. 3G); head slightly less transverse, dorsal surface with punctures more deeply impressed and often confluent (Fig. 3F); pronotum with sides more strongly explanate; sternite V with basal line weakly (male) or not projected posteriad (female) at middle; median lobe in lateral view with small expansion in apical fourth, with small pair of lateral teeth (Fig. 9I); paramere distinctly longer than median lobe, slightly constricted in apical fourth, apex not attenuate (Fig. 9J); peg setae in medial group not extended basad of marginal group, both groups becoming indistinguishable at apex, medial groups not divergent and situated on midline (Fig. 9K); male sternite IX not distinctly widened at midlength, markedly more elongate; female tergite X shorter, with slightly broader apex.
Distribution
Figure 19B. Known from a single locality in Guizhou, China.
Bionomics
The type series was collected in September at an elevation of 1450–1500 m.
Comments
Bolitogyrus nigerrimus is most similar to B. metallicus and can only be distinguished by characters on the aedeagus including the median peg setae, which are not on a ridge or extended basad, the larger lateral teeth of the paramere and larger subapical expansion of the median lobe in lateral view. The paramere was drawn in the original description (Yuan et al. 2007[1]) with more than two macrosetae on the lateral margin when, in fact, there are only the usual two.
