Cremnops tibiomaculatus Berta

[ Plate 25 , Figs A–I]

Cremnops tibiomaculatus Berta de Fernandez, 1998. Female.

Diagnosis. This species is distinguished by the hind trochantellar carina, 3–5 pitted sternaulus, extremely narrow subpronopes partition, pale colored scape, and black abdomen on a mostly orange species.

Description. Holotype: female. Body length 9.5 mm (9–10 mm).

Head (Figs C & F). Forty-one (38–42) flagellomeres. Lateral carina of frons weak, ending immediately anteriad lateral ocellus. Interocellar space not elevated, level with lateral ocelli. Malar space 0.8x (0.8–1.0x) 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. 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 4 (3–5) pits; about 1/ 2x (to 2/ 3x) length of mesopleuron. Discrimen smooth. Medial propodeal areola with 3 (3–4) 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 symmetrical, broad, angled quadrangular-shaped.

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 2.5x apical width, apical width about 1.5x basal width.

Biology. Host —Unknown.

Body Color Orange, except black as follows: metasoma (except first median tergite) distal part of hind tibia; scape orange.

Adults Collected —April and June to August.

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

Comments. This species is probably closely related to C. apicalipennis and C. willinki , as they all have a trochantellar carina and narrow subpronopes partition.

Etymology. The name refers to the dark spot on the hind tibia ( Berta 1998).

Material examined. HOLOTYPE: Cremnops tibiomaculatus , female, 8 mi. south Elota Sin. Mexico, vii- 2–1963, ( CNC) (H8929). Non-Types: 2 ( MCZ), 1 ( FSCA), 3 ( ESSIG), 1 ( CNC), 2 ( MNHN), 2 ( HIC). For holotype and additional images see Appendix VIII.
