Crassomicrodus mariae Figueroa, Sharkey & Romero ZBK sp. n. Fig. 7 a–e
Description female.
Body. Length. 5.13-5.38 mm. Color (Fig. 7e). Integument black except yellowish-orange as follows, basal area of mandible, tegulae, femora, fore and middle tibia; medial area of hind tibia pale yellow; ocelli translucent yellow; apical area of mandible reddish; tarsomeres and apical area of hind tibia blackish; tergum dark brown; sternum and wing veins brown; forewing lightly infumate with a hyaline spot on the first submarginal cell that is similar in size to the parastigma. Head (Fig. 7ab). Transverse in frontal view; face with longitudinal ridge dorsomedially; eye height/width = 1.35-1.42; eye height 0.67 –0.72× inter-ocular distance; area between antennal sockets with a median pyramidal-shaped elevation; frons not excavated; posterior surface of antennal sockets smooth; groove between lateral ocelli smooth; median ocellus separated from lateral ocellus by smooth groove; gena bulging; malar space 0.38 –0.43× as long as eye height; clypeus 2.53 –2.67× wider than high; length of ventrolateral margin of clypeus distinctly longer than diameter of tentorial pit; antenna with 25 flagellomeres; setae at base of mandible distinctly longer than setae on rest of body surface. Mesosoma (Fig. 1cde). Pronotum punctuate; lateral pronotal margins with weakly crenulate groove; notauli not impressed; anterolateral edges of scutellum lacking small acute projection; scutellar disc convex with sparse setae from 0.09 to 0.10 mm in length; scutellar disc sloped posteriorly and rounded; lateral scutellar depression smooth centrally and microfoveolate on the margins; carinae of central metanotal area almost circular shaped; propodeum reticulate rugulose, more pronounced on lateral margins; subalar lobe separated from mesopleuron by narrow rugulose groove, width distinctly shorter than the subalar lobe; ventral one-fourth of metapleuron reticulate punctuate, remainder smooth. Legs. Inner spur of middle tibia 0.67 –0.74× length of basitarsus; inner spur of hind tibia 0.52 –0.53× length of basitarsus; metabasitarsus 1.35 –1.42× length of tarsomeres III, IV, and V combined; hind tibia 2.21 –2.30× longer than basitarsus; hind femur length 3.14 –3.23× its maximum width. Wings. Forewing length/width = 2.07-2.17; stigma 2.65 –2.75× longer than maximum width; forewing vein R1 0.48 –0.50× as long as vein RS; vein RS slightly sinuate; vein r arising at middle of stigma; second submarginal cell triangular, with petiole 0.03-0.06 mm long; vein M+CU not pigmented throughout; hind wing length/width = 2.96-3.30; hind wing vein 1M 2.00 –2.35× longer than 1r-m; hind wing with 4 hamuli. Metasoma. Apical width of petiole (tergum 1) 2.17 –2.38× wider than basal width; minimum width of petiole 0.70 –0.77× apical width; length of ovipositor sheath 0.76-0.78 mm.
Male.
Similar to female except male has 26-28 flagellomeres, carinae of central metanotal area almost pentagonal shaped, 4-5 hamuli.
Host.
Unknown
Distribution.
USA.
Diagnosis.
Distinguished from other Crassomicrodus species by the following combination of characters: area between antennal sockets with a median pyramidal-shaped elevation, frons not excavated, antenna with 25 flagellomeres, notauli not impressed, length of ovipositor sheath 0.76-0.78 mm, forewing vein R1 0.48 –0.50× as long as vein RS, head and mesosoma black, and wings lightly infumate.
Remarks.
This species is near to Crassomicrodus muesebecki , but differs in that Crassomicrodus muesebecki measures 6.08 a 6.95 mm, area between antennal sockets with a median transverse elevation and two weakly defined lateral tubercles, frons deeply excavated, antenna with 28-29 flagellomeres, pronotum more smooth, sparse setae on scutellar disc from 0.18 to 0.20 mm in length, length of ovipositor sheath 1.83-2.33 mm, and coloration of metasoma is black.
Etymology.
This species is named in honor of María Espinosa Morales, wife of the first author.
