Cremnops bertae NEW SPECIES

[ Plate 3 , Figs A–I]

Diagnosis. This species is distinguished by its prominent scutal flange, 4–8 hind tibial spines, and symmetrical hind claw inner teeth.

Description. Holotype: female. Body length 7.0 mm (7.0–8.0 mm).

Head (Figs C & F). 35 (34–37) flagellomeres. Lateral carina of frons weak, ending immediately anteriad lateral ocellus. Interocellar space not elevated, level with lateral ocelli. Malar space 1.1x (0.8–1.2x) eye height.

Mesosoma (Figs D, E & H). Subpronopes adjacent, separated by a partition narrower than (or about to equal) the longitudinal length of the dorsomedial portion of pronotum. Median mesonotal lobe weakly depressed medially. Notaulus smooth. Scutellar sulcus with 1 longitudinal carina. Hind margin of posterolateral scutal flange prominent; strongly acute (straight to weakly curved, but NOT as strongly curved as in C. comstocki ). Mesoscutellar trough without (to with) longitudinal carinae laterally. Metanotal trough without extensive longitudinal carinae laterally. Sternaulus with 5 (4–6) pits; about 1/ 2x (1/3–1/ 2x) length of mesopleuron. Discrimen smooth (to foveolate). Medial propodeal areola with 4 (3–4) transverse carinae. Metapleuron rugose on ventral 1/2 (to 1/3).

Hind leg (Fig. I). Femur length about 3x width. Trochantellar carina absent (or present, but weak). Distal tibia with 6 (4–8) spines. Inner tooth of inner and outer claws symmetrical, narrow and angled (to curved), with 4 basal pectines.

Fore wing (Fig. G). Melanic; veins melanic; stigma melanic. 2nd submarginal cell about as high as wide. Hyaline spot in anterior part of 1st submarginal cell and basal part of 2nd discal cell.

Metasoma (Figs A & B). 1st median tergite length about 2x apical width, apical width about 2.5x basal width.

Body Color Orange, except black as follows: head, sternum, mid leg, and hind trochanter, trochantellus, tibia and tarsus (head color varies to all orange).

Biology. Host —Unknown.

Adults Collected —March, May, June–August, October.

Geographic Range —Nova Scotia, west to Colorado, and south to Florida. See map in Appendix II.

Comments. Cremnops bertae is similar to C. shenefelti and C. haematodes , but can be distinguished by the prominently projecting scutal flange (compared to non-prominent 90° to obtuse hind angle of the scutal flange in C. shenefelti and C. haematodes ) and narrow hind femur (length 3x width in C. ashmeadi compared to 2x width in C. shenefelti ). Cremnops bertae can be distinguished from C. ashmeadi by the greater number of hind tibial spines (4–8 in C. ashmeadi compared to 2–3).

Etymology. Dedicated to Dominga Carolina Berta De Fernandez for her work on Neotropical Cremnops .
