Length: male 3.9–4.3 mm, female 4.0–4.2 mm.

Ground colour of body reddish brown. Vertex yellow posteriorly, gradually suffused with reddish orange anteriorly, or sometimes almost entirely reddish orange; borders at eyes yellow; ocelli greyish surrounded with whitish yellow; coronal suture reddish brown. Frontoclypeus orange except basal part reddish orange, anteclypeus light orange, in some specimens frontoclypeus and anteclypeus entirely orange except base of frontoclypeus reddish orange; genae, anteocular areas and antennal bases whitish. Pronotum mostly orange brownish, surrounded with irregular arch of patches along anterior margin in addition to three sordid creamy patches. Scutellum centrally with a broad sordid cream stripe, basal angles brownish orange, scutoscutellar sulcus black. Forewing hyaline, costal margin, wax field and most of part of vein c and cell c tan. Thorax and legs beige except 1st tibia and tarsus brown. Abdomen blackish brown, laterally sordid yellow sprinkled with irregular blackish brown patches and spots on sternites. Female abdomen sordid brownish ventrally, ovipositor sordid brown to brown ochre.

Abdominal apodemes reaching end of segment 6 ( Fig. 12 ). Male Pygofer elongate, caudal 1/3 narrowed, terminally rounded with about 10 rigid setae, anterior margin sinuate ( Fig. 5 ); ventral appendage narrow and nearly parallel sided, slightly sinuate over whole length with indistinct ledge marking elongate apical area ( Figs 5, 6 ). Subgenital plate in profile long, basal 1/3 broad and nearly parallel sided, gradually tapering apicad dorsally, with 3–5 setae in basal group, about 25 marginal microsetae, 22 lateral macrosetae and several long fine setae in 2–3 rows ( Figs 5, 7 ). Paramere broad, apically with short and compact dentifer bearing 5–6 teeth, 2–3 setae and 5–7 sensory pits below ( Fig. 8 ). Aedeagal shaft declined at almost right angle from preatrium, in profile nearly same width over whole length, curved upwards with notched apex, gonopore apical on dorsal surface; atrial rim scoop like laterally with pair of short laterally curved processes caudo-ventrally ( Figs 9, 10 ). Connective broad, apical margin deeply emarginate medially ( Fig. 11 ). Anal tube process long, reaching further basad than half height of pygofer, sinuate and tapering to acute apex ( Figs 5, 9 ).

Etymology. The name refers to the similarity of the new species to A. fuscus Dworakowska.

Diagnosis. Alebroides parafuscus n. sp. is a member of the A. fuscus species group based on the following combination of characters: anal tube process reaching further basad than half the height of pygofer ( Fig. 5 ); subgenital plate gradually tapering apicad ( Fig. 7 ); paramere with short dentifer ( Fig. 8 ); connective broad ( Fig. 11 ); aedeagal shaft declined from preatrium, the latter scoop like laterally, gonopore dorsal ( Fig. 9 ). It differs from A. fuscus by: pygofer with caudal 1/3 narrowed and terminally rounded with anterior margin sinuate ( Fig. 5 ); abdodminal apodemes reaching end of segment 6 ( Fig. 12 ); anal tube process sinuate towards apex ( Figs 5, 9 ); aedeagus with paired atrial processes curved and separate from the aedeagal shaft in caudal view ( Figs 9, 10 ).
