Cremnops marshi Berta

[ Plate 16 , Figs A–I]

Cremnops marshi Berta de Fernandez, 1998. Female.

Cremnops punctatus Berta de Fernandez, 1998. Female. NEW SYNONYMY.

Diagnosis. This species is distinguished by its distinctive short malar space, primarily black coloration, hind trochantellar carina, and elevated interocellar space.

Description. Holotype: female. Body length 7.5 mm (7.0– 8.5 mm).

Head (Figs C & F). 40 (38–43) flagellomeres. Lateral carina of frons weak, ending immediately anteriad lateral ocellus. Interocellar space elevated, higher than lateral ocelli. Malar space 0.5x (0.5–0.8x) eye height. Apical tooth of mandible not extending past margin of basal lobe.

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 foveolate (to smooth). Scutellar sulcus with 1 longitudinal carina. Hind margin of posterolateral scutal flange not prominent; rather: 90° to obtuse (to lobed). Mesoscutellar trough with (to without) longitudinal carinae laterally. Metanotal trough without extensive longitudinal carinae laterally. Sternaulus with 2 (1–2) pits; about 1/ 4x (or less) length of mesopleuron. Discrimen smooth (to foveolate). Medial propodeal areola with 4 (3–5) transverse carinae. Metapleuron rugose on ventral 1/2 (to almost entirely).

Hind leg (Fig. I). Femur length about 2.5– 4 x width. Trochantellar carina present. Distal tibia with 2 spines. Inner tooth of inner and outer claws symmetrical, broad, angled quadrangular-shaped.

Fore wing (Fig. G). Melanic, or hyaline with melanic tint; veins melanic; stigma melanic. 2nd submarginal cell slightly higher than wide (to 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 1.5x apical width, apical width about 3x basal width.

Body Color Black, except orange as follows: metasoma, and hind leg.

Biology. Host —Unknown.

Adults Collected —June to August.

Geographic Range — Mexico. See map in Appendix II.

Comments. Similar to C. montrealensis . Cremnops marshi can be differentiated by the elevated, as opposed to level, interocellar space.

Etymology. Dedicated to the Braconidae specialist at the National Museum on Washington, Dr. Paul Marsh ( Berta 1998).
