Male
(
Fig.11A
): Very similar to female, except by the lateral height of head 0.86–0.89× the size of mesopleuron; mandibular apex 0.72–1× as wide as base; malar space 0.29–0.37× as long as basal width of mandible; width of supraclypeal area 1.16–1.25× its height; spiracle width 0.5–0.62× the spiracle height; propodeum neck 0.63–0.86× the size of hind coxae; fore leg with height of t1 0.72–0.78× height of fore t2–t5, mid legs with height of t1 0.8–0.9× height of mid t2–t5 and hind legs with height of t1 0.74–0.91× height of mid t2–t5; length of tergite II 0.75–0.82× length of tergite I;
2/RS
0.5–0.77× the size of
2/M
; hind legs with t2–t4 or t3–t4 pale-yellow; metasomal tergites I–II and V–VIII darker than female; gonoforceps and cercus also black.
Biology
: Host unknown.
Comments
: Very similar to
Charops angelicae
sp. nov.
from which it can be differentiated by the dark brown scape, with a thin pale-yellow line on its apex; dark brown pedicel (vs the bicolored scape and pedicel, anteriorly yellow and posteriorly brown) and width of supraclypeal area 1.20–1.37× its height (vs width of supraclypeal area 1.11–1.18× its height).
Etymology
: This species is named in honor of Maria Tereza Guarnieri Doria first author’s grandmother.
