Description.
Male
(
holotype
). Body length
2.8 mm
. Head and pronotum dark brown, elytra yellowish to reddish, with vaguely outlined dark markings: base, transverse band at about midlength, apices and suture all brownish (
Fig. 143
); femora brown, tibiae and tarsi yellowish-brown, antennae reddish-brown in basal half, dark brown in apical half.
Head elongate, 1.2 times as long as wide, somewhat widely rounded posteriorly; eyes large, rather convex. Surface moderately glossy, distinctly and rather densely punctate; punctures well-spaced; setation short, subdecumbent, with scattered erect setae.Antennae slightly enlarged in apical half; antennomeres X 1.2 times, XI 2.4 times as long as wide.
Pronotum nearly as long as wide, distinctly narrower than head including eyes, evenly rounded anteriorly, pronotal disc moderately convex, outline in dorsal view with lateral margins nearly straightly narrowing posteriorly. Surface moderately glossy, minutely, densely punctate; punctation and setation as on head.
Elytra 1.8 times as long as wide; humeri distinctly protruding; omoplates slightly indicated; apices modified, channel of gland forming minute cavity at pointed protrusion of margin. Surface moderately glossy, minutely and rather densely punctate; punctation more delicate than on head, setation as on head, with scattered short erect setae.
Legs slender, simple; all tibiae with paired terminal spurs.
Abdominal sternum VII slightly produced and unevenly rounded apically; sternum VIII forming paired, slender and strongly elongate, sabre-like sclerites (
Fig. 92
). Aedeagus (
Figs 6
,
88
): tegmen flatly produced and narrowly emarginate apically; endophallic armature with two pairs of robust, claw-like spines and some simple, randomly scattered spinules.
Female.
Identical with male for most external characters; elytral apices simple; sternum VII simple; tergum VII simple, subtriangular, evenly rounded apically.
Variation.
Body length (
♀
)
2.2–3.1 mm
; dark markings of elytra varying in extent and prominence, some speci- mens from Wadi Al Mughsayl extremely dark, with two pairs of small yellowish spots on elytra; male abdominal sternum VII unevenly rounded to slightly emarginate apically.
Differential diagnosis.
Microhoria cervi
sp. nov.
belongs to the
M. schimperi
species-group. It is externally very similar to
M. almukalla
sp. nov.
from
Yemen
, differing by its markedly larger eyes, coarser punctation on the head, by the strongly narrowed and elongate sabre-like sclerites of male sternum VIII (simple, subtriangular in
M. cervi
sp. nov.
), and by characters of the aedeagus (cf.
Figs 88
versus
86).
Etymology.
Named in honour of the late Czech entomologist Radek Červenka, nicknamed ‘Červ’ by friends, who collected the
holotype
and some of the
paratypes
of this species.
Distribution.
Oman
