Cremnops willinki Berta

[ Plate 31 , Figs A–I]

Cremnops willinki Berta de Fernandez, 1998. Female.

Diagnosis. This species is distinguished by the short malar space, very narrow subpronopes partition, and carina on the hind trochantellus.

Description. Holotype: female. Body length 8 mm (7.5–9.5 mm).

Head (Figs C & F). Forty (38–42) flagellomeres. Lateral carina of frons weak, ending immediately anteriad lateral ocellus. Interocellar space not elevated, level with lateral ocelli. Malar space 0.5x (0.5–0.7x) 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 the longitudinal length of the dorsomedial portion of pronotum. Median mesonotal lobe depressed medially (sometimes weakly). Notaulus smooth. Scutellar sulcus with 1 longitudinal carina. Hind margin of posterolateral scutal flange not prominent; rather: 90° to obtuse (to lobed). Mesoscutellar trough without longitudinal carinae laterally. Metanotal trough without extensive longitudinal carinae laterally. Sternaulus with 1 pit (or absent); about 1/ 4x (or less) length of mesopleuron. Discrimen smooth. Medial propodeal areola with 5 (3–5) transverse carinae. Metapleuron rugose on ventral 1/3.

Hind leg (Fig. I). Femur length about 3x width. Trochantellar carina present. Distal tibia with 2 spines. Inner tooth of inner and outer claws asymmetrical, broad, angled quadrangular-shaped.

Fore wing (Fig. G). Hyaline with melanic tint; 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 1.2x basal width.

Body Color Orange, except black as follows: distal part of hind tibia and hind tarsus.

Biology. Host —Unknown.

Adults Collected —July to September.

Geographic Range — Mexico south to Honduras. See map in Appendix II.

Comments. This species is similar to C. virginiensis and C. ferrugineus , but can be differentiated by the narrow (instead of wide) subpronopes partition.

Etymology. In honor of Dr Abraham Willink's continued support of Berta de Fernandez' s scientific training ( Berta 1998).

Material examined. HOLOTYPE: Cremnops willinki , female, La Primavera, Jalisco, Mexico, 7–8–1956, R. & K. Dreisbach, ( USNM) (H8924). Non-Types: 6 ( ESSIG), 6 ( FSCA), 1 ( CAS), 1 ( CNC), 1 ( MCZ), 1 ( UAIC). For holotype and additional images see Appendix VIII.
