Megymenum lisi View in CoL n. sp.

ETYMOLOGY The new species is dedicated to Professor Jerzy A. LIS (University of Opole, an eminent specialist in Dinidoridae and Cydnidae )

DIAGNOSIS

Megymenum lisi is very similar to M. salebrosum LIS in its body outline and sculpture. Nevertheless, it can easily be separated by its smaller preocullar processes (figs 1, 5), larger and sharper processes of collar­like structure, larger antero­lateral margins projecting forwards to form rounded processes (figs 2, 6) and less pointed hypophysis of parameres (figs 4, 8).

DESCRIPTION

Body brown without metallic tinge, elongate, abdomen slightly broader than pronotum.

Head (fig. 5) slightly punctate; paraclypei concave, much longer than clypeus and joined in front of it; preocular surface distinctly swollen with very small processes, eyes round, protruding, brown, ocelli of the same colour as head; ocular index about 5.6; distance between ocelli about 1.21 times longer than distance between ocellus and eye; antennae similarly coloured as head, 4­segmented, 1 st segment short and not reaching apex of head, 2 nd longest, 3 rd and 4 th subequal and slightly dilated; rostrum light brown, reaching mid­coxae, 1 st segment extending beyond base of head, buccula lobed anteriorly incrised, surface convex and rugose.

Pronotum (fig. 6) with numerous fine ridges and puncture­like spots; anterior border drawn forwards to form a collar­like structure behind base of head, with sharp and narrow teeth at the corners; antero­lateral margins projecting forwards to form small, rounded processes, lateral borders irregular, with small projections; posterior angles rounded; posterior border straight at base of scutellum, anterior median tuberosity very large and conspicuous.

Scutellum with dispersed puncture­like spots; cavity­like depressions present at basal angles of scutellum.

Hemelytra narrower than abdomen, corium slightly longer than scutellum, membrane creamy coloured, not reaching posterior extremity of abdomen.

Legs uniformly coloured, as rest of body, femora with small spines on undersurface, spines extending in 2 rows only near apex of femora (about 4 spines), female hind tibia slightly dilated.

Meso­ and metasternum with a deep median groove; scent gland spout large and conspicuous, evaporatoria wrinkled.

Abdomen. Abdominal connexivum not covered by hemelytra, conspicuous; posterior lateral corners of segment with a rounded apical lobe and a small median lobe occupying more than half­length of abdominal segments (fig. 7); sterna punctate; spiracles of first visible abdominal sternum not covered by metasternum, placed in linear arrangement near lateral margins and closer to anterior intersegmental border of each segment.

Male genitalia very similar to M. salebrosum , but differ in the shape of paramere (figs 4, 8).

Female genitalia: 9 th paratergite similar to M. salebrosum , 1 st valvifers with distinguished median and lateral elevation.

Measurements (in mm) (male followed by female): body length 14.82, 16.0; body width 8.56, 8.86; head length 2.4, 2.65; head width 3.15, 3.2; pronotum length 4.3, 4.5; pronotum width 7.05, 7.45; scutellum length 3.95, 4.1; scutellum width 4.0, 4.25; antennal segments: 0.85:2.3:1.6: and 0.8:2.3:1.55:1.5.
