Type species

Gompholopium quercicola gen. et sp. nov.

Diagnosis

The new genus differs from all other genera of the tribe Monophlebini in the presence of lanceolate conical setae, densely covering the body and in the presence of the discoidal wax glands with stalked centre.

Morphologically, the new genus seems to be the most similar to the Palaearctic Pseudaspidoproctus Morrison, 1927 and Nearctic Llaveiella Morrison, 1927 in the presence of numerous conical setae (see the figure and the key for genera in Gavrilov-Zimin 2018: 154, 158).

Etymology

The generic name was constructed from the Ancient Greek words ‘γόμφος’ (‘nail, spine’) + ‘λωπίον τό’ (‘clothes’), the gender is neuter.

Description

Adult female

Body broadly oval, covered by solid wax plates ( Fig. 1 ). Antennae 9-segmented. Legs normally developed; claw without denticle; claw digitules short, setose. Mouthparts well developed. Abdominal spiracles numbering 7 pairs; each abdominal spiracle with unilocular atrium, without wax pores inside or just near spiracular atrium. Anal apparatus represented by a short tube with internal sclerotized anal ring. Fifteen round cicatrices forming semicircle on abdominal sternites. Wax glands represented by four main types of discoidal wax glands: 1) variable pores with stalked centre; 2) usual multilocular pores with round or oval central loculus and 10–12 peripheral loculi; 3) irregular multilocular pores with multiform central loculus and 6-10 peripheral loculi; 4) simple pores. Conical setae very numerous, with more or less lanceolate apices. Flagellate setae of different size and thickness numerous.

Male and larval instars

Unknown.
