Coccidella HAMBLETON, 1946 b

Type species: Morrisonella poensis HAMBLETON, 1946 b

Description: Body elongate oval. Antennae 5 or 6 segmented, typical for the tribe, but the sensory seta on fifth segment is narrow and long, when the species has five segmented antennae it is situated near to the base of the fifth segment. Legs well developed. Dorsum and venter with tritubular pores (cerores). Tubular ducts absent or present. Anal ring normal, with 6 setae, cells in small number, outer row cells with spicula. Ostioles present, circulus absent. Internal genital organ heavily sclerotized, usually as long as width of one segment.

Distribution: The genus contains eight species, all are from the Neotropical Region ( Fig. 1 ).

Comments: This genus was synonymized by FERRIS (1953), and latter HAMBLETON (1946 b) accepted this act. However, FERRIS (1953) was not entirely sure about his decision and noted “It may seem desirable to resurrect the genus Coccidella and to name even more.” The present re-establishment is based on several newly described species and the study of type material, which gave possibility to find some new characters, and describe more definitely the genus, which follows HAMBLETON’ s (1946 a) description, but adds several new and important characters, which were not considered by him.

Coccidella HAMBLETON, 1946 b , is a replacement name of Morrisonella HAMBLETON, 1946 a . This genus is distinct from other genera by having groups of trilocular pores with special structures on some of the ventral segments of the abdomen.

The 3rd segment is almost parallel sided. The apical segment has four falcate sensory setae, one of them narrow, 31 µm long, blunt seta. Most segments of the antenna have a few hair-like setae; the longest one is 22 µm. Eyes well visible. Anal lobe is slightly developed with three long, hair-like setae.

Venter. Labium appears two-segmented, 76 µm long. Stylet loop three times longer than labium. Cephalic plate not visible. Legs robust: coxa of anterior legs 51 µm, trochanter 48 µm, femur 118 µm, tibia 77 µm, tarsus 67 µm, and claw 24 µm. Coxa of middle legs 65 µm, trochanter 50 µm, femur 103 µm, tibia 70 µm, tarsus 58 µm, and claw 26 µm long. Coxa of posterior legs 72 µm, trochanter 50 µm, femur 122 µm, tibia 98 µm, tarsus 70 µm, and claw 29 µm, tarsal digitules absent, claw digitules short, 8 µm long. Trochanter with two pores on each side. Claw without denticle. Legs with few hair-like setae, tibia and tarsus with 13 µm long setae. On the ventral segments few tritubular pores, 7 µm in diameter present on margin, diameter of tubes 4 µm. Few multilocular pores with ten pores present around vulva, and some scattered in the midline of the thorax, 8 µm in diameter. The diameter of anterior spiracles 17 µm. Venter with a small number of scattered hair-like setae. Circulus absent. Tubular ducts absent. Trilocular pores widely distributed on venter. On the segments IV and V, and on the head a group of special trilocular pores present, 4 µm in diameter, the structure appears as tritubular. Internal genitalia, forming a characteristic, particularly elongate structure, as long as two segments; near the basal part the vagina enlarged; vaginal glands not seen.

Dorsum. Ostioles present, sclerotized. Multilocular pores absent. Anal ring oval, 41 µm wide and 37 µm long. Anal ring with six, 54 µm long hair-like setae. Anal ring pores (cells) typical, in small number, with small spicules on pores of outer row. Tritubular pores of one size, 1–3 on each segment, 10 µm in diameter, ducts short, diameter of tubes 4 µm. Tubular ducts absent. Hair-like setae 11 µm long, trilocular pores 3 µm wide, scattered on the dorsum.

Distribution: Bolivia and Peru ( Fig. 1 ).

Etymology. The species is named after the country of origin.

Affinities: The species is similar to C. theobromae , but differs from it by having short and wide tritubular pores, and five segmented antennae.
