description: 14. Dryinus schueeppi Olmi, sp. nov.
(Figs 2, 3)
Etymology. This species is named after the collector, Christof Schüepp.
Types. Holotype, ♀, BELIZE: Corozal District, Sarteneja, Mesatonich Road, Farmland/Agroforestal, 18°19.847'N 88°8.776'W, 3 m a.s.l., 22–28.i. 2010, Malaise trap 3, C. Schüepp coll. (BER).
Diagnosis. Head rugose, unusually excavated; eye very bulging; POL shorter than greatest breadth of each posterior ocellus; OL about eleven times as long as POL; prothorax black, except lateral and posterior margin of pronotum, including posterior tubercles, testaceous; fore wing with three dark transverse bands; propodeum without strong transverse keel between dorsal and posterior surface.
Description. Female (Fig. 3): fully winged; length 7.6 mm. Head black, except mandible, clypeus, part of gena and anterior margin of face between and around antennal toruli testaceous; palpus brown; antenna testaceous, except segments 4–5 and distal extremity of 3 brown; rest of segment 3 whitish; mesosoma black, except lateral and posterior margin of pronotum testaceous; pronotal tubercle testaceous; metasoma brown-testaceous; proleg brown, except tarsus, stalk of femur and part of tibia testaceous; mesoleg and metaleg brown, except metatrochanter testaceous. Antenna clavate; antennal segments in following proportions: 19:7:41:19:15:12:9:8:7:10; rhinaria present in antennal segments 5–10. Head hairy, dull, rugose, very excavated, with eye very bulging; frontal line complete; occipital carina absent; temple absent; POL = 1; OL = 11; OOL = 10; POL much shorter than greatest breadth of posterior ocelli (1:3.5). Pronotum dull, hairy, sculptured by fine striae situated around disc, crossed by weak anterior transverse impression; pronotal tubercle not reaching fore tegula. Scutum and scutellum dull, reticulate rugose. Notauli absent. Metanotum shiny, hairy, punctate, without sculpture among punctures. Propodeum completely reticulate rugose, without transverse keel between dorsal and posterior surface; dorsal surface with some longitudinal keels connected by short transverse keels or areolae; posterior surface with two longitudinal keels and median area dull, rugose. Mesopleuron and metapleuron densely hairy, reticulate rugose. Fore wing with three dark transverse bands; distal part of stigmal vein longer than proximal part (20:14). Fore tarsal segments in following proportions: 21:4:10:21:40. Enlarged claw not spatulate (Fig. 2), with large subdistal tooth and one row of 15 lamellae and 1 bristle. Segment 5 of fore tarsus (Fig. 2) with two rows of approximately 35 lamellae; distal apex with at least 30 lamellae. Tibial spurs 1, 1, 2.
Male: unknown.
Distribution. Only known in the type locality.
Hosts. Unknown.
Comments. According to the systematics of the Neotropical Dryinus proposed by Olmi (1993b), D. schueeppi belongs to ruficauda group. Because of the head rugose and unusually excavated, the eye very bulging and POL shorter than greatest breadth of each posterior ocellus, the female of D. schueeppi is similar to that of D. putus Olmi 1998. The main differences between these two species are the following:
1 Prothorax testaceous-reddish; fore wing with two dark transverse bands; propodeum with strong transverse keel between dorsal and posterior surface; head with OL about three times as long as POL........................... D. putus (Olmi)
- Prothorax black, except lateral and posterior margin of pronotum, including posterior tubercles testaceous; fore wing with three dark transverse bands; propodeum without strong transverse keel between dorsal and posterior surface; head with OL about eleven times as long as POL................................................ D. schueeppi Olmi sp. nov.
