Type locality.

Karen Hills, Kayin State, Myanmar.

Type material.

Holotype (♂, IRSNB): Carin Cheba, 900-1100m, L. Fea, V XII-88 [printed] / Coll. et det. A. Fauvel, Cyrtothorax vulneratus , R.I.Sc.N.B. 17.479 [printed] / HOLOTYPE Bolitogyrus feai Brunke, des. A. Brunke 2017 [red label] / AJB0000426 [identifier label].

Diagnosis.

This species may be recognized by the following: head entirely dark; pronotum widest in posterior third; elytra partly dark, discal markings of elytra extending onto epipleuron, forming v-shape (as in Fig. 2E); epipleuron entirely pale (as in Fig. 7C); antennomere 8-9 weakly transverse (Fig. 7E); frons with only vague traces of microsculpture.

Description.

Measurements ♂ (n = 1): HW/HL 1.42; PW/PL 1.33; EW/ EL 1.22; ESut/PL 0.86; PW/HW 0.94; forebody length 4.6 mm.

Similar to B. solodovnikovi and differing only in the following: epipleuron entirely pale (Fig. 7C); pronotum with broad medial darkening; apical antennomere slightly paler (Fig. 7E); elytral suture relatively longer than pronotum at midline; pronotum slightly narrower than head; abdominal tergite VI entirely dark and punctate medially; antennomeres without distinctly darkened apices; median lobe in lateral view with apical portion more strongly narrowed to apex and slightly sinuate, not distinctly hooked, without basal teeth (Fig. 16M); median lobe in parameral view with shorter, acuminate apical portion (Fig. 16L); paramere about as long as median lobe, less elongate, peg setae arranged in shorter marginal group, median group composed of larger peg setae placed in a broader row basad of marginal group (Fig. 16O); male sternite VIII with shallower emargination. Female unknown.

Distribution.

Figure 21A. Known from the Karen Kills (Kayin State) in Myanmar.

Bionomics.

The holotype was collected in May at 900-1100 m.

Etymology.

This species is named after Leonardo Fea (1852-1903), an Italian explorer and naturalist who collected a rich variety of Bolitogyrus specimens from Myanmar.

Comments.

Bolitogyrus feai is most similar to B. mulayitensis from southern Myanmar but can be distinguished by the longer apical antennomeres and the presence of only traces of microsculpture on the frons.
