Holotype

(♀, NMW): Costa Rica, Carpintera, leg. Nevermann [white hand printed label]/ ♀ [white printed card]/ Cyrtothorax Nevermanni , n. sp./ Allotypus [red printed label]/ Nevermanni, Scheerp. [green hand printed card]/ ex. coll. Scheerpeltz [blue printed label]/ TYPUS, Cyrtothorax , nevermanni, O. Scheerpeltz [red hand printed label]/ Holotype ♀, Cyrtothorax nevermanni Scheerpeltz, 1974, det. A. Brunke 2013 [red printed label] / Bolitogyrus costaricensis (Wendeler) Det. A. Brunke 2012 [white printed label].

The single specimen located in NMW is interpreted as the holotype as Scheerpeltz (1974) stated that only one specimen was seen. Although this holotype is also female, it can be associated with the same species concept as the type of Bolitogyrus costaricensis for the same reasons (above). Therefore, Bolitogyrus nevermanni (Scheerpeltz) becomes a synonym of Bolitogyrus costaricensis (Wendeler).

Diagnosis.

Head without central protuberance; antenna and legs distinctly bicolored (Fig. 5A; 11G); genital and abdominal segments VIII not distinctly paler than previous segments; abdominal sternites with fine transverse microsculpture, interspaces about as wide as lines (Fig. 13D); female procoxa completely dark; median lobe recurved at apex (Fig. 15F); paramere with convergent arms; paramere with fields of peg setae wide and circular at base of arms (Fig. 15 G–H); female tergite X with raised disc converging strongly toward apex, strongly pigmented area not or weakly incised at apicolateral margin (Fig. 25 A–D); female secondary gonocoxite not distinctly swollen at base.

Redescription.

Measurements ♂ (n=5): HW/HL 1.54-1.62; PW/PL 1.29-1.67; EW/EL 1.24-1.26; ESut/PL 0.68-0.80; PW/HW 1.10-1.25; forebody length 4.1-4.9 mm.

Measurements ♀ (n=5): HW/HL 1.50-1.67; PW/PL 1.35-1.47; EW/EL 1.21-1.30; ESut/PL 0.75-0.78; forebody length - 4.5-5.1 mm.

Morphology as in Bolitogyrus buphthalmus , differing only in the following: metallic reflections of body bronze to greenish or grayish-bronze or violet to violet-blue; median lobe in lateral view recurved dorsad (Fig. 15F); peg setae fields broad and circular at base of parameral lobe (Fig. 15 G–H); male sternite IX with apical emargination deeper (Fig. 23B); female tergite X with strongly pigmented area not or weakly incised lateroapically (Fig. 25 A–D).

Distribution.

Figure 29 A–B. Bolitogyrus costaricensis is known from Guatemala, Honduras, Nicaragua and Costa Rica, west to the northern part of the Talamanca Cordillera. Two females from Belize were seen that might belong to this species or Bolitogyrus buphthalmus . The specimen from Limón province in Costa Rica was almost certainly collected from elsewhere as Parismina is a city located on the Caribbean coast, situated at sea level, which is distinctly outside the elevational range of this species.

Bionomics.

Most specimens of Bolitogyrus costaricensis have been collected by pyrethrum fogging of fungusy logs, while others were collected from bracket fungi, dried mushrooms, small crustose polypores, fungi in the family Xylariaceae , various woody debris and in FIT or Malaise traps; one slightly teneral specimen came to light. Bolitogyrus costaricensis has been collected in forests at elevations ranging from 600-2062 m in every month of the year.

Comments.

Bolitogyrus costaricensis is most similar to Bolitogyrus buphthalmus and can only be separated from it by characters on the aedeagus (see above).
