description: Coridiellus pseudocyclopeltus sp. nov. (Figs. 1, 2)
Diagnosis. Externally the new species is similar to Coridiellus cyclopeltus (Fig. 3), but could easily be separated by the color of the 5 th segment of antennae, which is light brown or almost yellow, legs light brown, and also by the shape of paramere (Fig. 2). The same characters in C. cyclopeltus are, respectively: the color of 5 th segment of antennae is black, legs dark brown or black, shape of paramere is different (Fig. 4).
Description:
Body elongate ovoid, black and blackish brown, with pale scutellum, legs and 5 th antennal segment.
Head. Small, triangular almost flat, paraclypei longer than anteclypeus and joined in front of it, lateral margin very slightly sinuated in front of eyes; eyes blackish brown with the yellow tinge; antennae almost black colored but 5 th segment with a tinge of yellow, 1 st segment reaches apex of head, 2 nd minute, 3 rd and 5 th almost the same length, 4 th slightly smaller than 5 th; rostrum 4 segmented, extending to middle of mesocoxae, 2 nd longest, 3 rd and 4 th short and subequal; bucculae rounded.
Thorax. Pronotum with black band along anterior border; surface with puncture like spots; anterior margin deeply concave; lateral margins widely arched; posterior margin sinuate at ends and almost straight at base of scutellum.
Scutellum the same color like corium and membrane, lateral margin sinuate, apex large and rounded.
Corium longer than scutellum.
Membrane exceeds posterior extremity of abdomen, some basal cells distinct, with numerous longitudinal veins. Mesosternum grooved medially; scent gland spout prolonged into a tongue-like extension, brown.
Legs almost similarly colored as venter but lighter than dorsum, femora finely spined (four very small spines present on undersurface of femora), posterior tibiae of female slightly dilated, tarsi 3 segmented.
Abdomen. Connexivum exposed, black; spiracles of 1 st visible abdominal sternum covered by metasternum; spiracles placed in linear arrangement near lateral margins of abdomen and closer to antherior intersegmental border of segments.
Male genitalia. Pygophore with distinct ventral rim, paramere with characteristic thumb-like processus with some hairs at the apex and with rounded and swollen border with distinct appendix (Fig. 2).
Female genitalia. Spermatheca sac-like, lightly sclerotized, spermathecal bulb round, flanges well separated, sclerite with two horns.
Etymology. The name of new species is related to similar Coridiellus cyclopeltus (Distant, 1890).
