Type material.
HOLOTYPE: 1 ♂ (UMM172, AMNH) from Honduras,
14.5036
-86.3206
9, 650 m a.s.l.. PARATYPE: 1 ♀ (8568, SMF) from Finca San Jorge, Santa Ana, Santa Ana, San Salvador,
13.9778
-89.5647
5, 1000 m a.s.l., 25.iv.1951. Female paratype was originally misidentified as
Ummidia zilchi
(Krauss, 1955).
Etymology.
The specific epithet is a noun (feminine, singular) taken in apposition and is in reference to the type locality and its people.
Diagnosis.
Ummidia hondurena
can be differentiated from all other geographically proximate species except
U. riverai
and
U. rugosa
by the presence of a comb of alternating large and small strong setae on the retrolateral face of tarsus IV (Fig.
3C
). Males can be differentiated from
U. zilchi
,
U. carlosviquezi
,
U. varablanca
, and
U. quepoa
by possessing a sinuous embolus, rather than one with an even single curve and from
U. yojoa
and
U. varablanca
by having many more prolateral (26 vs 0) and retrolateral (29 vs 2-3) spines on tibia I. Males can be further distinguished from
U. riverai
and
U. rugosa
by lacking a pale dorsal heart patch on the abdomen. Females can be distinguished from all geographically proximate species except
U. rugosa
and
U. erema
by having spermathecae which bend first medially and then anteriorly.
