Gregikia pallida, new species

Figures 41–43, Plate 4D

DIAGNOSIS: As for genus.

DESCRIPTION: Body length = 3.77 mm (holotype)/ 3.09 –3.65 mm (paratypes); wing length = 3.26 mm (holotype)/ 2.36–3.76 mm (paratypes). Head: Vertex setose. Scape and pedicel small. Flagellum 14­segmented. Flagellomeres cylindrical, length 2Χ the width, covered by trichia, length of trichia about one­half flagellomere width. Only three segments of palpi visible; segments short, nearly cylindrical, combined length slightly less then head height. Thorax: Scutum with erect setae, arranged in rows with wide bare strips between them, acrostichal setae absent. Antepronotum and proepisternum setose. Proepimeron touches mesepisternum at anepisternal suture. Scutellum with four pairs of setae. Anepimeron very narrow ventrally, so that laterotergite touches katepisternum. Katepisternum larger than anepisternum. Mediotergite, laterotergites, and metepisternum bare. Wing: Costa ends slightly beyond tip of R 5. Sc meets C at level of RS base. R stem, R 1, R 5, and distal parts of M 1 and M 2 with setae. R 5 not reaching wing apex. Section RS1 oblique. R 4 transverse. Ratios of lengths of RS1, RS2, and RS3 is 1:1.5:12– 15. Length of crossvein r­m about equal to RS1 and 0.25Χ M3 section. M 1 subparallel to R 5; veins M 1, M 2, M 3+4, and CuA divergent. Base of fork of M 3+4 and CuA proximal to M3 base. M 3+4 and CuA curved gently. M 1, M 2, M 3+4, and CuA with a few setae on apical part. Legs: Hind coxae with long dor­ solateral setae. Mid tibiae without sensory pit. Tarsal claw with one basal tooth. Abdomen densely setose. Segments 7 and 8 short, about one­half length of segment 6. Tergite 9 short, does not cover gonocoxites. Gonocoxites densely setose, with long, slim apical and basal lobes, pointed caudally and bearing numerous inner setae. Gonostyli ovate, bare, with strong dark apical processes.

ETYMOLOGY: The species epithet is a Latin word pallidus meaning ‘‘pale’’ in reference to state of preservation of the specimen.
