Centromeriana jocosa – Melichar 1912: 45 (record from Sierra Leone).

Diagnosis

Centromeriana lindbergae sp. nov. is very similar to C. jocosa in size, coloration and body structure but can be differentiated from the latter by the structure of the male genitalia: the segment X (anal tube) which is broad in dorsal view and with broad and blunt apical lobes, weakly projecting ventrad in lateral view (in C. jocosa , the segment X is much narrower and elongate in dorsal view and with narrow, sharp, hook-like apical lobes strongly projecting ventrad in lateral view); and the aedeagus which has relatively short and only slightly curved endosomal processes, the apices of which are directed dorso-posteriad (in C. jocosa , the endosomal processes are longer and more strongly curved, with apices directed dorso-anteriad), and the ventral lobes of the phallobase are more slender, convergent and tapering apically, but divergent medially (in C. jocosa , they are robust and thumb-like, broad apically and confluent medially). Centromeriana lindbergae sp. nov. differs from C. rhinoceros sp. nov. in the presence of a brownish macula on the forewing apex and a less inclined cephalic process. Centromeriana lindbergae sp. nov. differs from C. simplex in a darker body coloration pattern, the presence of a brownish macula on the forewing apex, and the structure of the male genitalia, particularly a broader segment X (narrower in C. simplex ), obtusely angled dorsoposterior margin of pygofer (right-angled in C. simplex ), a more slender and sicle-shaped gonostyle (robust and triangular in C. simplex ), and the aedeagus with long endosomal processes (absent in C. simplex ) and differently shaped and sized lobes of the phallobase ( C. simplex has large and broad triangular dorsal lobes, expanded laterally).

Etymology

The new species is named after Ms. Gunvi Lindberg, manager of the Hemiptera collection and the microscopic slide collection at the Naturhistoriska riksmuseet, Stockholm, Sweden, in recognition of her kindest help and support to the first author when he visited NHRS in 2014.

Type material examined

Holotype

SIERRA LEONE: ♂, “Sierra Leone, no date and collector [white printed label]; NHRS-GULI 000009124 [white printed label]; HOLOTYPE [newly added red printed label]; ♂, Centromeriana lindbergae sp. nov., det. Z.S. Song, I. Malenovský & A.P. Liang, 2016 [newly added red printed label]” ( NHRS, dry-mounted: pinned through mesonotum, right wing apex missing, abdomen detached and stored in glycerine in a glass microvial).

Paratype

SIERRA LEONE: 1 ♂, “Sierra Leone [white printed label]; jocosa Gerst , det. Melichar [white handwritten and printed label]; Hung. Nat. Hist. Mus., Budapest, coll. Hemiptera [yellow printed label]; PARATYPUS ♂, Centromeriana lindbergae sp. nov., det. Z.S. Song, I. Malenovský & A.P. Liang, 2016 [newly added red printed label]” ( HNHM, dry-mounted: pinned through mesonotum, abdomen detached and stored in glycerine in a plastic microvial).

Description

LENGTH. Body length (from apex of head to tip of forewings): ♂ 14.3 mm; head length (including two portions: the former is from apex of cephalic process to constricted and curved part, and the latter is from curved part to base of eyes): ♂ (0.7–0.8)+(1.1–1.2); head width (including eyes): ♂ 1.6 mm; forewing length: ♂ 11.4–11.9 mm.

COLORATION AND EXTERNAL MORPHOLOGY ( Figs 1B , 3B , 6 A–C). Largely identical to C. jocosa .

MALE GENITALIA. Pygofer in lateral view ( Fig. 6E ) similar to C. jocosa , ventral margin much longer than dorsal one with ratio of ventral to dorsal length about 4.2:1; dorso-posterior margin obtusely angular. Gonostyles ( Fig. 6 E–G) identical to C. jocosa , sicle-shaped, narrow basally, slightly expanding towards apex, broadest subapically; dorsal claw-like process large, elongate, and acute apically. Aedeagus with endosomal processes ( Fig. 6 H–J) relatively short, membranous, slightly inflated, acute apically, slightly curved with apices directed obliquely dorso-posteriad, apex with minute spines; phallobase sclerotized and pigmented at base, membranous and inflated apically, with one pair of thumb-like dorsolateral lobes, directed anteriad, apex with numerous minute spines ( Fig. 6H ), a pair of long and relatively slender, curved ventral lobes, divergent medially, convergent and tapering apically with some minute superficial spines ( Fig. 6 I–J). Segment X large and broad in dorsal view, ratio of length to width near middle about 1.3:1 ( Fig. 6D ); in lateral view, with broad and blunt apical lobes, weakly projecting ventrad ( Fig. 6E ).

Female unknown.

Distribution

Sierra Leone.

Remark

The paratype specimen from HNHM was misidentified and erroneously reported under C. jocosa by Melichar (1912).
